Lighter units make for easy replacement. Simple, fast plug-in connections to the standard integrated terminal board. Clearly la- beled connection points to reduce in- stallation time. Also, a large control box provides room to work and room to mount Carrier accessory controls. Easy to maintain Easy access handles by Carrier provide quick and easy access to all normally serviced components. Our “no-strip” screw system has superior holding power and guides screws into position while preventing the screw from strip- ping the unit’s metal. Easy to use The optimized, central terminal board by Carrier puts all connections and troubleshooting points in one conve- nient place. Most low voltage connec- tions are made to the same board and make it easy to access it. Carrier roof- tops have high and low pressure switches, a filter drier, and 2-in. filters standard. Our optional digital control- lers allow for seamless and simple inte- gration to the most complex building network. Streamlined control and inte- gration Carrier controllers make connecting WeatherMaster rooftops into existing building automation systems easy. The units are compatible with conventional thermostat controls, Carrier Premier- Link™ communicating controls, Com- fortLink controller, and Carrier RTU Open multi-protocol controller inter- face with BACnet, Johnson Controls N2, LonWorks, or Modbus protocols. WeatherMaster rooftops also seamless- ly integrate with Carrier building sys- tem options like the Carrier VVT® zon- ing system, or the Carrier i-Vu® Building Automation System. Operating efficiency and flexi- bility The 48HC rooftops exceed ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) 90.1-2016, IECC (Interna- tional Energy Conservation Code) IECC-2015 minimum efficiency requirements. Field convertible airflow (3 to 12.5 ton) All WeatherMaster® units are field- convertible to horizontal air flow, which makes it easy to adjust to unexpected jobsite complications. Be- ing able to convert a unit from vertical airflow to horizontal also makes it easy to overcome jobsite complications. 12.5 ton models require a simple sup- ply air ductcover to field convert from factoryvertical to horizontal. EnergyX models are limited to vertical returnbut supply can be field convert- ed. Staged Air Volume (SAV™) Two-Speed Indoor Fan Control System with variable frequen- cy drive (VFD) Optional SAV system utilizes a variable frequency drive (VFD) to automatically adjust the indoor fan motor speed be- tween operating modes. Available on 2-stage cooling models 07-14 with electro-mechanical, ComfortLink, or RTU Open controls. Comfort control Carrier’s patentedHumidi-MiZer adap- tive dehumidificationsystem is an all- inclusive factory installed option on gas heating/electric cooling and electric heat/electric cooling models.

Optimum performance Thermostatic expansion valve (TXV) on each refrigerant circuit helps pro- vide optimum performance across the entire unit operating range. Power exhaust To aid in building pressure control Car- rier EnergyX® systems include ECM power exhaust fans as standard. The ComfortLink controller integrates the power exhaust into ERV operation while also ensuring precise building pressure control. Moisture control Carrier's EnergyX ® system provides the added benefit of significantly rais- ing humidity level of incoming outdoor air in the winter and lowering humidity level of incoming outdoor air in the summer. This humidity control can eliminate additional equipment require- ments, discomfort, health problems, and increase indoor air quality for a building. Humidi-MiZer® adaptive dehu- midification system Carrier's Humidi-MiZer adaptive dehu- midification system is an all-inclusive factory-installed option that can be or- dered with any WeatherMaster® 48HC04-14 rooftop unit (with the ex- ception of single-phase voltage 208- 230/1/60). This system expands the envelope of operation of operation of Carrier WeatherMaster® rooftop prod- ucts to provide unprecedented flexibili- ty that will meet year-round comfort conditions. WeatherMaster® is the next genera- tion version of Carrier's Humidi-MiZer system and includes modulating refrig- erant valves that provide variable flow bypass around the condenser. This in- novative feature ensures exact control of the supply-air temperature as the unit lowers the evaporator temperature to increase latent capacity. The Humidi-MiZer adaptive dehu- midification system has the industry's only dual dehumidification mode setting. The WeatherMaster® rooftop, coupled with the Humidi-MiZer adap- tive dehumidification system, is capable of operating in normal design cooling mode, sub-cooling mode, and hot gas reheat mode. In the normal design cooling mode the unit will operate under the normal sequence of operation. The Humidi- MiZer system is inactive. In the sub- cooling mode the controller will control the refrigeration system to satisfy cool- ing and dehumidification requirements, as well as providing adequate reheat to maintain the desired supply-air tem- perature. Hot gas reheat mode will operate when the space requires dehumidifica- tion only. The controller will control the refrigeration system to provide la- tent capacity similar to that provided in the full sub-cooling mode. In addition, it can increase hot dis- charge gas bypass to the Humidi-MiZer coil in order to heat the air to the exact neutral state required - no over-cooling or overheating.

Outdoor sound data is measured in accordance with AHRI. 2. Measurements are expressed in terms of sound power. Do not compare these values to sound pressure values because sound pressure depends on specific environmental factors which nor- mally do not match individual applications. Sound power values are independent of the environment and therefore more accurate. 3. A-weighted sound ratings filter out very high and very low frequen- cies, to better approximate the response of “average” human ear. A-weighted measurements for Carrier units are taken in accor- dance with AHRI. 48HC UNIT COOLING STAGES OUTDOOR SOUND (dB) AT 60 HZ A- WEIGHTED 63 125 250 500 1000 2000 4000 8000 A04 1 76 78.2 78.0 74.2 73.3 70.6 66.0 62.4 56.9 A05 1 78 84.7 83.6 77.1 74.6 72.3 68.3 64.7 60.9 A06 1 77 87.5 82.5 76.1 73.6 71.3 67.1 64.1 60.0 A07 1 82 90.1 82.6 81.0 79.4 77.0 73.0 70.4 66.7 D07 2 82 90.1 82.6 81.0 79.4 77.0 73.0 70.4 66.7 D08 2 82 90.6 84.3 80.2 79.3 77.1 72.2 67.4 63.7 D09 2 82 88.6 85.0 81.6 79.5 77.4 74.1 71.0 66.3 D11 2 87 85.9 87.9 85.6 84.4 82.8 78.5 74.9 72.5 D12 2 87 85.9 87.9 85.6 84.4 82.8 78.5 74.9 72.5 D14 2 83 89.3 86.0 82.9 80.7 78.5 73.6 69.6 64.5 dB — Decibel Capacity ratings (cont) 7 MINIMUM - MAXIMUM AIRFLOW RATINGS (CFM) — NATURAL GAS AND PROPANE — Not Available * Heating rating values are identical for aluminum heat exchang- ers and stainless steel heat exchangers VOLTAGE 48HC UNIT HEAT LEVEL COOLING HEATING* Minimum Single Speed Fan Motor Minimum 2-Speed Fan Motor (at high speed) Minimum 2-Speed Fan Motor (at low speed) Maximum Minimum Maximum Single Phase 04 LOW 900 — — 1500 900 1970 MED 800 1520 HIGH — — 05 LOW 1200 — — 2000 900 2470 MED 1050 2280 HIGH 1230 2190 06 LOW 1500 — — 2500 900 3290 MED 1050 2730 HIGH 1230 2820 Three Phase 04 LOW 900 — — 1500 990 2190 MED 1010 1550 HIGH — — 05 LOW 1200 — — 2000 990 2190 MED 1330 2460 HIGH 1390 2220 06 LOW 1500 — — 2500 990 2730 MED 1330 2880 HIGH 1390 2780 07 LOW 1800 1800 1200 3000 990 3640 MED 1330 4750 HIGH 1390 3750 08 LOW 2250 2535 1673 3750 1900 4750 MED 2100 3900 HIGH 2270 3780 09 LOW 2550 2550 1683 4250 1900 4750 MED 2100 4560 HIGH 2270 4250 11 LOW 3000 3380 2231 5000 1900 4750 MED 2100 4560 HIGH 2270 4250 12 LOW 3000 3380 2231 5000 2100 5470 MED 2620 5670 HIGH 2650 5290 14 LOW 3750 4225 2789 6250 1880 7500 MED 2450 6750 HIGH 3000 7200 8 HEAT RATING TABLE — NATURAL GAS AND PROPANE NOTES: 1.

It communicates with the Weather- Master® ComfortLink controller via a UPC translator mod- ule which connects to the WeatherMaster rooftop unit’s ComfortLink controller via a LEN cable. All controller set- tings and configuration are input via the ComfortLink scrolling marquee display. All control points, including outdoor airflow, exhaust air- flow and CO2 setpoints are configured via the Com- fortLink scrolling marquee interface. NOTE: CO2 sensor requires a factory installed economizer. The EnergyX energy recovery unit pre-conditions the out- door air before it mixes with the return air and enters the rooftop unit evaporator coil. As a result, the EnergyX oper- ation is mostly independent of the rooftop unit operation except to allow the space conditioning needs to be met without RTU compressor operation or RTU heat opera- tion for a significantly wider range of ambient temperatures (than a unit without an energy recovery module). This is achieved either by the pre-conditioning of the EnergyX wheel or the economizer (if equipped). The EnergyX sys- tem will pre-condition the outside air in the cooling and heating modes of operation. Energy recovery devices such as the EnergyX® system typ- ically result in substantial energy savings over other out- door air devices. Specifically, the EnergyX system adds sensible and latent capacity as well as additional stages of cooling and heating operation to the rooftop unit. Due to the EnergyX system’s significantly lower input watts than the corresponding RTU compressor(s), proper control strategies for this device maximize its operation to reduce the run time of the RTU compressor(s). This results in a much higher system efficiency than can typically be achieved by using a rooftop unit of the same total capacity. The EnergyX system with its modulating airflow capabil- ity allows a designer to increase the amount of outside air significantly more than normal with the following benefits: • Reduced rooftop unit sizing - The more air that passes through the energy recovery device reduces the load (and potential unit size) on the rooftop unit’s compres- sors and heating system. • Higher system cooling and heating efficiencies — Since the EnergyX wheel uses the power of ‘rotary enthalpy transfer’ as opposed to mechanical compression condi- tioning of the ventilation air resulting in a much higher operating efficiency (RER) of the energy recovery unit and system Combined Efficiency Factor (CEF). The higher the airflow through the EnergyX wheel, the higher the system efficiency (CEF) value. Since the EnergyX system also conditions ventilation air in the heating mode, the necessary amount and/or operation of the rooftop unit heat system is reduced. • Better part load conditioning — As the EnergyX system is able to modulate its airflow, the ability to match the changing zone part-load capacity (in cooling and in heating) is greatly increased. • Higher air change rates — Larger amounts of ventila- tion air allows the zone air to be flushed out more often. This can contribute significantly to reduced sickness and more productive operating environments. All ventilated spaces are good candidates for energy re- covery systems. The applications that benefit most are those that require a large amount of outside air for a space that has a low internal load. This is true because most out- side air loads are latent which requires a larger rooftop unit to accommodate both internal and ventilation loads. Ad- vantages of the ERV unit include the ability to reduce the size of the rooftop unit, provide better humidity levels and provide a stable, tempered space. Examples of ERV applications are classrooms, church- es, conference rooms, game rooms, auditoriums, movie theaters, day care centers, nursing homes, funeral homes, dormitories, and clinics. Retrofits of existing systems to handle outside air without modifying the rooftop unit are excellent applications. Other examples are bars, restau- rants, casino/game rooms, barber/beauty shops, bingo halls, locker rooms, recreational facilities and health clubs. Animal shelters such as veterinary clinics and kennels have been very successful implementations. Retail spaces and manufacturing facilities are also good applications. If the outside air requirement is greater than 10% of a rooftop unit’s supply air rating the EnergyX unit should be considered to enhance the comfort of the occupants and reduce the tonnage of the rooftop unit. Carrier’s Packaged RTU Builder selection software program offers a quick, simple look at the advantages and payback of the EnergyX system. EnergyX® with economizer (3-phase models only) — Allows true modulating economizer capability when OA is suitable for free cooling. • operates as a true wheel bypass • uses stop/jog operation for wheel required when using CO2 sensor for DCV operation • economizer integrated into EnergyX unit EnergyX® with frost protection (3-phase models only) — Senses pressure differential across the energy re- covery cassette. Uses exhaust air to defrost the wheel when necessary.

This system expands the envelope of operation of Carrier’s WeatherMaster rooftop products to pro- vide unprecedented flexibility to meet year round comfort conditions. The Humidi-MiZer adaptive dehumidification system has a unique dual operational mode setting. The Humidi- MiZer system provides greater dehumidification of the oc- cupied space by two modes of dehumidification operations in addition to its normal design cooling mode. The WeatherMaster® 48HC04-14 rooftop coupled with the Humidi-MiZer system is capable of operating in normal design cooling mode, sub-cooling mode, and hot gas re- heat mode. Normal design cooling mode is when the unit will operate under its normal sequence of operation by cy- cling compressors to maintain comfort conditions. Sub-cooling mode will operate to satisfy part load type conditions when the space requires combined sensible and a higher proportion of latent load control. Hot Gas Reheat mode will operate when outdoor temperatures diminish and the need for latent capacity is required for sole humid- ity control Hot Gas Reheat mode will provide neutral air for maximum dehumidification operation. Thru-the-base connections — Thru-the-base connec- tions, available as a factory option, are necessary to ensure proper connection and seal when routing wire and piping through the rooftop’s basepan and curb. These couplings eliminate roof penetration and should be considered for gas lines, main power lines, as well as control power. Hinged access panels — Allows access to unit’s major components with specifically designed hinged access pan- els. Panels are filter, control box, indoor fan motor and ERV access. Cu/Cu (indoor) coils — Copper fins and copper tubes are mechanically bonded to copper tubes and copper tube sheets. A polymer strip prevents coil assembly from con- tacting the sheet metal coil pan to minimize potential for galvanic corrosion between coil and pan. E-coated (outdoor and indoor) coils — A flexible ep- oxy polymer coating uniformly applied to all coil surface areas without material bridging between fins. Coating pro- cess shall ensure complete coil encapsulation of tubes, fins and headers. Pre-coated outdoor coils — A durable epoxy-phenolic coating to provide protection in mildly corrosive coastal en- vironments. The coating minimizes galvanic action be- tween dissimilar metals. Coating is applied to the alumi- num fin stock prior to the fin stamping process to create an inert barrier between the aluminum fin and copper tube. Condenser coil hail guard — Sleek, louvered panels protect the condenser coil from hail damage, foreign objects, and incidental contact. Smoke detector (supply and/or return air) — Trust the experts. Smoke detectors make your application safer and your job easier. Carrier smoke detectors immedi- ately shut down the rooftop unit when smoke is detected. They are available, installed by the factory, for supply air, return air, or both. Single enthalpy sensor — Prevents the wheel from ro- tating if the outside air conditions are acceptable for free cooling. Both exhaust and supply blowers will remain on. Unit mounted CO2 sensor — Improves productivity and saves money by working with the economizer to intake only the correct amount of outside air for ventilation. As occupants fill your building, the CO2 sensor detects their presence through increasing CO2 levels, and opens the economizer appropriately. When the occupants leave, the CO2 levels decrease, and the sensor appropriately closes the economizer. This intelligent control of the ventilation air, called demand controlled ventilation (DCV) reduces the overall load on the rooftop, saving money. Stainless steel heat exchanger — The stainless steel heat exchanger option provides the tubular heat exchanger be made out of a minimum 20 gauge type 409 stainless steel for applications where the mixed air to the heat ex- changer is expected to drop below 45°F (7°C). Stainless steel may be specified on applications where the presence of airborne contaminants require its use (applications such as paper mills) or in area with very high outdoor humidity that may result in severe condensation in the heat ex- changer during cooling operation. Convenience outlet (powered or un-powered) — Re- duce service and/or installation costs by including a conve- nience outlet in your specification. Carrier will install this service feature at our factory. Provides a convenient, 15 amp, 115v GFCI receptacle with “Wet in Use” cover. The “powered” option allows the installer to power the outlet from the line side of the disconnect or load side as required by code. The “unpowered” option is to be powered from a separate 115/120v power source. The unpowered convenience outlet is available as a 15 amp factory-installed option or a 20 amp field-installed accessory. Non-fused disconnect — This OSHA-compliant, facto- ry-installed, safety switch allows a service technician to lo- cally secure power to the rooftop. HACR circuit breaker — These manual reset devices provide overload and short circuit protection for the unit. Factory wired and mounted with the units with access cov- er to help provide environment protection. On 575V applications, HACR breaker can only be used with WYE power distribution systems. Use on Delta power distribution systems is prohibited. Options and accessories (cont) 19 Foil-faced insulated cabinet — Cabinet is fully insulated with non-fibrous, foil-faced cleanable insulation that is se- cured and encapsulated in unit design. PremierLink™ DDC controller — This CCN (Carrier Comfort Network®) regulates your rooftop’s performance to tighter tolerances and expanded limits, as well as facili- tates zoning systems and digital accessories. It also unites your Carrier HVAC equipment together on one, coherent CCN network. The PremierLink controller can be factory- installed, or easily field-installed. The controller is not avail- able when SAV (Staged Air Volume) 2-speed indoor fan or EnergyX is installed. ComfortLink controller — Models with the optional Carrier ComfortLink controls allow added unit diagnostics and operation setup capabilities. ComfortLink comes stan- dard with units equipped with EnergyX. The ComfortLink control is your link to a world of sim- ple and easy to use rooftop units that offer outstanding performance and value. It optimizes the performance of the refrigeration circuits as conditions change, resulting in the following features: • Better control of temperature and humidity • Superior reliability • Automatic redundancy • Low ambient cooling operation to 0°F (–18°C) • More accurate diagnostics, at unit or remote The ComfortLink scrolling marquee is very easy to use. The messages are displayed in easy to understand English, no decoding is required. A scrolling readout provides de- tailed explanations of control information. Only four, large, easy-to-use buttons are required to maneuver through the entire menu. The readout is designed to be visible even in the brightest sunlight. A hand held Navigator™ acces- sory or wall-mounted System Pilot™ accessory can be used for added service flexibility. The ComfortLink control provides unparalleled service diagnostic information. Temperature and pressure can be read directly from the display with no need for separate gauges. Other data, such as compressor cycles, unit run time hours, current alarms, can also be accessed. A history of alarms is also available for viewing. The service run test can be very helpful when trouble- shooting. The user can run test major components to de- termine the root cause of a problem. The unit can be run- tested before an installation is complete to ensure satisfac- tory start-up. To ensure reliability, the ComfortLink control prevents reverse compressor rotation. No laptop comput- ers are required for start-up. Time schedules are built in and the Scrolling Marquee display provides easy access to setpoints. The ComfortLink control accepts input from a CO2 sensor and a smoke de- tector. Both are available as factory-installed options or as field-installed accessories. RTU Open, multi-protocol controller — Connect the rooftop to an existing BAS (building automation system) without needing complicated translators or adapter mod- ules using the RTU Open controller. The RTU Open controller speaks the 4 most common building automation system languages (BACnet, Modbus, Johnson Controls N2, and LonWorks). Use this controller when you have an existing BAS. Besides the 4 protocols, it also communi- cates with a Carrier Open system (i-Vu® and VVT®). Not compatible when EnergyX is installed. Time Guard II control circuit — This accessory pro- tects your compressor by preventing short-cycling in the event of some other failure, prevents the compressor from restarting for 30 seconds after stopping. Not required with PremierLink™ controller, RTU Open controller, Com- fortLink controller, or authorized commercial thermostats. Condensate overflow switch — This sensor and related controller monitors the condensate level in the drain pan and shuts down compression operation when overflow conditions occur. It includes: • Indicator light — solid red (more than 10 seconds on water contact — compressors disabled), blinking red (sensor disconnected) • 10-second delay to break — eliminates nuisance trips from splashing or waves in pan (sensor needs 10 sec- onds of constant water contact before tripping) • Disables the compressor(s) operation when condensate plug is detected, but still allows fans to run for Econo- mizer. Power exhaust with barometric relief — Superior in- ternal building pressure control. This field-installed acces- sory may eliminate the need for costly, external pressure control fans. Low ambient controller — The low ambient controller is a head pressure controller kit that is designed to maintain the unit’s condenser head pressure during periods of low ambient cooling operation. This device should be used as an alternative to economizer free cooling when economiz- er usage is either not appropriate or desired. The low am- bient controller will either cycle the outdoor fan motors or operate them at reduced speed to maintain the unit opera- tion, depending on the model. This controller allows cool- ing operation down to –20°F (–18°C) ambient conditions. (Not available on size 11 models as standard unit cooling operation down to 0°F /–18°C.) Field-installed accessories Filter maintenance indicator — When the optional fac- tory-installed filter maintenance indicator is used, a factory- installed differential pressure switch measures pressure drop across the outside air filter and activates a field-sup- plied dry contact indicator when the pressure differential exceeds the adjustable switch setpoint. Condenser coil hail guard — Sleek, louvered panels protect the condenser coil from hail damage, foreign ob- jects, and incidental contact. This can be purchased as a factory-installed option or as a field-installed accessory. Differential enthalpy sensor — The differential enthal- py sensor is comprised of an outdoor and return air enthal- py sensors to provide differential 20 Options and accessories (cont) Wall or duct mounted CO2 sensor — The IAQ sensor shall be available in duct or wall mount. The sensor pro- vides demand ventilation indoor air quality (IAQ) control. Propane conversion kit — Convert your gas heat roof- top from standard natural gas operation to Propane using this field-installed kit. High altitude conversion kit — High altitudes have less oxygen, which affects the fuel/air mixture in heat exchang- ers. In order to maintain a proper fuel/air mixture, heat ex- changers operating in altitudes above 2000 ft (610 m) re- quire different orifices. To select the correct burner orifices or determine the heat capacity for a high altitude applica- tion, use either the selection software, or the unit’s service manual. High altitudes have less oxygen, which means heat exchangers need less fuel. The new gas orifices in this field-installed kit make the necessary adjustment for high altitude applications. They restore the optimal fuel to air mixture and maintain healthy combustion on altitudes above 2000 ft (610 m). NOTE: Typical natural gas heating value ranges from 975 to 1050 Btu/ft3 at sea level nationally. The heating value goes down approximately 1.7% per every thousand feet el- evation. Standard factory orifices can typically be used up to 2000 ft (610 m) elevation without any operational issues. Flue discharge deflector (sizes 04-12 only) — The flue discharge deflector is a useful accessory when flue gas recirculation is a concern. By venting the flue discharge up- wards, the deflector minimizes the chance for a neighbor- ing unit to intake the flue exhaust. Display kit for SAV™ system with VFD — Allows the ability to access the VFD controller programs to provide special setup capabilities and diagnostics. The kit contains a display module, mounting bracket, and communication cable. The display kit can be permanently installed in the unit or used on any SAV system VFD controller as needed. Winter start kit — The winter start kit by Carrier extends the low ambient limit of your rooftop to 25°F (–4°C). The kit bypasses the low pressure switch, preventing nuisance tripping of the low pressure switch. Other low ambient pre- cautions may still be prudent. Motormaster® head pressure controller — The Mo- tormaster motor controller is a low ambient, head pressure controller kit that is designed to maintain the unit’s con- denser head pressure during periods of low ambient cool- ing operation. This device should be used as an alternative to economizer free cooling not when economizer usage is either not appropriate or desired. The Motormaster con- troller will either cycle the outdoor-fan motors or operate them at reduced speed to maintain the unit operation, de- pending on the model. This controller allows cooling oper- ation down to –20°F (–18°C) ambient conditions. Roof curb (14-in./356 mm or 24-in./610 mm) — Full perimeter roof curb with exhaust capability provides separate air streams for energy recovery from the exhaust air without supply air contamination. Horizontal roof curb adapter (vertical to horizontal airflow) — horizontal roof curb adapters — Used when horizontal supply and/or return is desired. Filter status indicator accessory — Monitors static pressure across supply and exhaust filters and provides in- dication when filters become clogged. Motorized exhaust damper accessory — Replaces the standard barometric exhaust damper blades with motorized (open/shut) damper (not compatible with EnergyX). 21 OPTIONS AND ACCESSORY WEIGHTS LEGEND — Not Available * For Humidi-MiZer® system and Motormaster® controller.

Contact your Carrier sales representative for assistance. IDetermine Heating and Cooling Loads II Make an Initial Guess at Cooling Tons: Refrigerant tons = Total Capacity Load / 12 MBH per ton EXAMPLE: Refrigerant tons = 72 / 12 = 6 tons III Look up the RTU (Rooftop Unit) TC and SHC: Page 57 shows that, at the application’s supply air CFM, mixed air and ambient temperatures, the 48HC*A07 supplies: TC = 73.6 MBH* SHC = 53.3 MBH* IV Calculate the Building Latent Heat Load LC LOAD = TC LOAD – SHC LOAD EXAMPLE: 72.0 MBH – 54 MBH = 18 MBH V Calculate RTU Latent Heat Capacity LC = TC – SHC LC = 73.6 MBH – 53.3 MBH = 20.3 MBH VI Compare RTU Capacities to Loads† Compare the rooftop’s SHC and LC to the build- ing’s sensible and latent heat loads. VII Select Factory-Installed Options (FIOP) Local code requires an economizer for any unit with TC greater than 65.0 MBH. VIII Calculate the Total Static Pressure External static pressure 0.67 in. wg Sum of FIOP / Accessory static +0.13 in. wg Total Static Pressure 0.80 in. wg IX Look Up the Indoor Fan RPM (Revolutions Per Minute) and BHP (Breaker Horsepower) Page 83 shows size 07 3 phase vertical fan perfor- mance, at 2100 CFM and ESP= 0.8, RPM = 712 and BHP = 1.17 X Convert BHP Into Fan Motor Heat Fan motor heat = 2.546* BHP/Motor Eff.** Fan motor heat = 3.7 MBH XI Calculate RTU Heating Capacity Building heating load 85.0 MBH Fan motor heat –3.7 MBH Required heating capacity 81.3 MBH XII Select a Gas Heater The heat ratings table on page 8 shows the heating capacities of the 48HCEA07. The 48HCEA07 = 103.0 MBH. Select the 48HCEA07. XIII Determine Electrical Requirements MCA (Minimum Circuit Amps)/MOCP (Maximum Overcurrent Protection) tables show the MCA and Breaker Size of a 48HC*A07 (without convenience outlet) as: MCA = 32.0 amps and MOCP = 50.0 amps Min. disconnect size: FLA (Full Load Amps) = 31.0 and LRA (Lock Rotor Amp) = 148. EnergyX® Unit Selection Procedure — When select- ing the WeatherMaster Series Unit and EnergyX® system to use on a given application, it is strongly recommended that the Carrier Packaged RTU Builder (PRB) Selection Software be used. This is because there are a number of variables which become complex when manual calcula- tions are performed, but can easily be accounted for in a computer operation. Most specifically, the AHRI certified ratings use Standard CFM values, but due to real world op- eration, variances in altitude and air density are very im- portant. The Carrier PRB software uses altitude corrected airflows (ACFM). If the outside air requirement is greater than 10% of a roof- top unit’s supply air rating the EnergyX system should be considered to enhance the comfort of the occupants and reduce the tonnage of the rooftop unit. Carrier’s Packaged RTU Builder selection software program offers a quick, simple look at the advantages and payback of the EnergyX system. Typical Energy Recovery unit selection involves the follow- ing steps: 1. Determine the zone cooling and heating requirements at the design conditions. 2. Select Energy Recovery unit based on desired outdoor airflow rate. * Unit ratings are gross capacities and do not include the effect of evaporator fan motor heat. See Step XI for determining amount of evaporator fan motor heat to subtract from total and sensible capacities to obtain net cooling and net sensible capacities. † Selecting a unit with a SHC slightly lower than the SHC LOAD is often better than oversizing. Slightly lower SHC's will help control indoor humidity, and prevent temperature swings. ** Indoor fan motor efficiency available in Electrical Information Tables. Use the decimal form in the equation, eg. 80% = .8. GIVEN: Mixed air dry bulb 80°F (27°C) Mixed air wet bulb 67°F (19°C) Ambient dry bulb 95°F (35°C) TCLOAD (Total Capacity Load) 72.0 MBH SHCLOAD (Sensible Heat Capacity Load) 54.0 MBH Vertical air supply 2100 CFM Heating load 85.0 MBH External static pressure 0.67 in. wg Electrical characteristics 230-3-60 Selection procedure 50 NOTE: It is recommended that the outdoor airflow and exhaust airflow rates be designed at the same or close to the same value. If the difference between the two airflows becomes large enough, the energy recovery unit’s cooling capacity, heating capacity and overall efficiency will be negatively impacted. 3. Calculate the Energy Recovery unit’s leaving air con- ditions and unit capacities based on the outside air- flow rate, temperature (dry bulb and wet bulb) and exhaust airflow rate and temperatures (dry bulb and wet bulb) at the design temperatures and maximum ventilation rate. 4. Subtract the Energy Recovery unit’s cooling and heat- ing capacities from the design zone requirements. 5. The value that remains is the necessary design size of the rooftop unit. 6. Use the Energy Recovery unit’s leaving air tempera- tures (dry bulb and wet bulb) as the ventilation air temperatures entering the rooftop unit to be mixed with the return air before passing through the rooftop unit’s evaporator. 7. After selecting the desired Energy Recovery unit and rooftop unit, use AHRI’s Guideline V to calculate the Combined Efficiency Factor (system EER).

Interpolation is permissible. Do not extrapolate. 2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static pressure caused by any FIOPs or accessories. 3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accesso- ries may add static pressure losses. Selection software is available, through your salesperson, to help you select the best motor/drive combination for your application. 4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, Carrier recommended the lower horsepower option. 5. For information on the electrical properties of Carrier motors, please see the Electrical Data section of this book. 6. For more information on the performance limits of Carrier motors, see the application data section of this book. 7. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors. Motors regulated by EPACT include any general purpose, T-frame (three-digit, 143 and larger), single-speed, foot mounted, polyphase, squirrel cage induction motors of NEMA (National Electrical Manufacturers Association) design A and B, manufactured for use in the United States. Ranging from 1 to 200 Hp, these continuous-duty motors operate on 230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does not have to be replaced by an EPACT compliant energy-efficient motor. Variable-speed motors are exempt from EPACT compliance requirements. 90 ECONOMIZER, BAROMETRIC RELIEF AND POWER EXHAUST PERFORMANCE — VERTICAL APPLICATIONS (EXCLUDES ENERGYX SYSTEMS) BAROMETRIC RELIEF FLOW - VERTICAL 3-10 TON BAROMETRIC RELIEF FLOW - VERTICAL 12.5 TON 0 500 1000 1500 2000 2500 0 0.05 0.1 0.15 0.2 0.25 0.3RELIEF FLOW (CFM)RETURN DUCT S TATIC PRE SSURE (in. wg) 12½-Ton VERTICAL ECONOMIZERS 0 500 1000 1500 2000 2500 0 0.05 0.1 0.15 0.2 0.25 0.3 RETURN DUCT STATIC PRESSURE (in. wg)RELIEF FLOW (CFM)3 - 5 TON 6 - 10 TON VERTICAL ECONOMIZERS RETURN AIR PRESSURE DROP - VERTICAL 3-10 TON RETURN AIR PRESSURE DROP - VERTICAL 12.5 TON 0 1000 2000 3000 4000 5000 6000 0 0.1 0.2 0.3 0.4 RETURN DUCT STATIC PRESSURE DROP (in. wg)RETURN AIR FLOW (CFM)VERTICAL ECONOMIZERS 3 - 5 TON 6 - 10 TON 0 1000 2000 3000 4000 5000 6000 0 0.1 0.2 0.3 0.4RETURN AIR FLOW (CFM)RETURN DUCT STATIC PRESSURE DROP (in. wg) 12½-Ton VERTICAL ECONOMIZERS 0 1000 2000 3000 4000 5000 0 0.1 0.2 0.3 0.4 0.5 STATIC PRESSURE (in. wg)FLOW(cfm)3 - 5 TON 6 - 12.5 TON VERTICAL POWER EXHAUST PERFORMANCE Performance data (cont) 91 ECONOMIZER, BAROMETRIC RELIEF AND POWER EXHAUST PERFORMANCE — HORIZONTAL APPLICATIONS (EXCLUDES ENERGYX SYSTEMS) BAROMETRIC RELIEF FLOW - HORIZONTAL 3-10 TON BAROMETRIC RELIEF FLOW - -HORIZONTAL 12.5 TON RETURN AIR PRESSURE DROP - HORIZONTAL 3-10 TON RETURN AIR PRESSURE DROP - HORIZONTAL 12.5 TON HORIZONTAL POWER EXHAUST PERFORMANCE 0 500 1000 1500 2000 2500 0 0.1 0.2 0.3 0.4 0.5 STATIC PRESSURE (in. wg)FLOW(cfm)3-12.5 TON 0 1000 2000 3000 4000 5000 6000 0 0.1 0.2 0.3 0.4 RETURN DUCT STATIC PRESSURE DROP (in. wg)RETURN AIR FLOW (CFM)3 - - HORIZONTAL ECONOMIZERS 5 6 TON 10 TON 0 500 1000 1500 2000 2500 0 0.05 0.1 0.15 0.2 0.25 0.3 RETURN DUCT STATIC PRESSURE (in. wg)RELIEF FLOW (CFM)3 - - HORIZONTAL ECONOMIZERS 5 6 TON 10 TON 0 1000 2000 3000 4000 5000 6000 0 0.1 0.2 0.3 0.4RETURN AIR FLOW (CFM)RETURN DUCT STATIC PRESSURE DROP (in. wg) HORIZONTAL ECONOMIZERS 12½ TON 0 500 1000 1500 2000 2500 0 0.05 0.1 0.15 0.2 0.25 0.3RELIEF FLOW (CFM)RETURN DUCT STATIC PRESSURE (in. wg) HORIZONTAL ECONOMIZERS 12½ TON 92 48HC UNITS WITH ENERGYX® SYSTEM — POWER EXHAUST PERFORMANCE 0 200 400 600 800 1000 1200 1400 0.00 0.20 0.40 0.60 0.80 1.00 1.20 1.40 1.60 1.80 2.00 EXTERNAL STATIC PRESSURE (in H20) CFMECONOMIZER MODE ERV MODE CFM0.00 0.20 0.40 0.60 0.80 1.00 1.20 1.40 1.60 0 200 400 600 800 1000 1200 1400 1600 1800 2000 ECONOMIZER MODE ERV MODE EXTERNAL STATIC PRESSURE (in H20) 48HC**04 48HC**05-06 CFM0 500 1000 1500 2000 2500 3000 3500 0.00 0.50 1.00 1.50 2.00 2.50 3.00 3.50 4.00 4.50 ECONOMIZER MODE ERV MODE EXTERNAL STATIC PRESSURE (in H20) 48HC**07 48HC**08-12CFM 0.00 0.50 1.00 1.50 2.00 2.50 3.00 0 200 400 600 800 1000 1200 1400 1600 1800 2000 2200 ECONOMIZER MODE ERV MODE EXTERNAL STATIC PRESSURE (in H20) CFM0 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 0.00 0.50 1.00 1.50 2.00 2.50 3.00 3.50 4.00 4.50 5.00 ECONOMIZER MODE ERV MODE EXTERNAL STATIC PRESSURE (in H20) 48HC**14 Performance data (cont) 93 48HC 08-12 TYPICAL POWER WIRING DIAGRAM, 208/230V AND 460V Typical wiring diagrams 94 48HC 08-12 TYPICAL CONTROL WIRING DIAGRAM Typical wiring diagrams (cont) 95 48HC 08, 09 TYPICAL POWER WIRING DIAGRAM, 208/230V AND 460V WITH OPTIONAL HUMIDI-MIZER® SYSTEM 96 48HC 08, 09 CONTROL WIRING DIAGRAM WITH OPTIONAL HUMIDI-MIZER® SYSTEM Typical wiring diagrams (cont) 97 48HC MODULATING ERV WIRING SCHEMATIC 98 48HC*A04-14 COOLING ELECTRICAL DATA 48HC UNIT*V-Ph-Hz UNIT VOLTAGE COMP 1 OFM (EA) IFM CMBST.

For information regarding a direct digital controller, see the start-up, operations, and troubleshoot- ing manual for the applicable controller. Electro-Mechanical Units with No Economizer Cooling (Single Speed Indoor Fan Motor) When the thermostat calls for cooling, terminals G and Y1 are energized. As a result, the indoor-fan contactor (IFC) and the compressor contactor (C1) are energized, causing the indoor-fan motor (IFM), compressor no. 1, and out- door fan to start. If the unit has 2 stages of cooling, the thermostat will additionally energize Y2. On two compres- sor units, the Y2 signal will energize compressor contactor no. 2 (C2), causing compressor no. 2 to start. On 2-Stage 07 units, the Y1 signal energizes the IFC and C1 contac- tor, causing the indoor fan and outdoor fan to start and the compressor to operate at 66% capacity. The Y2 signal will energize the compressor loader plug, allowing compressor to operate at 100% capacity. Regardless of the number of stages, the outdoor fan motor runs continuously while unit is cooling. Cooling (2-speed indoor fan motor) — Per ASHRAE 90.1-2016 and IECC-2015 standards during the first stage of cooling operation the VFD will adjust the fan motor to provide 66% of the total cfm established for the unit. When a call for the second stage of cooling is required, the VFD will allow the total cfm established for the unit (100%). Heating — NOTE: WeatherMaster® units have either 1 or 2 stages of gas heat. When the thermostat calls for heating, power is sent to W on the Integrated Gas Controller (IGC) board. An LED (light-emitting diode) on the IGC board turns on and re- mains on during normal operation. A check is made to en- sure that the roll-out switch and limit switch are closed. If the check was successful, the induced-draft motor is ener- gized, and when its speed is satisfactory, as proven by the flue gas pressure switch, the ignition activation period be- gins. The burners will ignite within 5 seconds. If the burn- ers do not light, there is a 22-second delay before another 5-second attempt. This sequence is repeated for 15 min- utes or until the burners light. If, after the 15 minutes, the burners still have not lit, heating is locked out. To reset the control, break 24 V power to the thermostat. When ignition occurs, the IGC board will continue to mon- itor the condition of the roll-out switch, the limit switches, the flue gas pressure switch, as well as the flame sensor. 45 seconds after ignition occurs, assuming the unit is con- trolled through a room thermostat set for fan auto, the in- door-fan motor will energize (and the outdoor-air dampers will open to their minimum position). If, for some reason, the over-temperature limit opens prior to the start of the indoor fan blower, the unit will shorten the 45-second de- lay to 5 seconds less than the time from initiation of heat to when the limit tripped. Gas will not be interrupted to the burners and heating will continue. Once the fan-on delay has been modified, it will not change back to 45 seconds until power is reset to the control. On units with 2 stages of heat, when additional heat is required, W2 closes and initi- ates power to the second stage of the main gas valve. When the thermostat is satisfied, W1 and W2 open and the gas valve closes, interrupting the flow of gas to the main burners. If the call for W1 lasted less than 1 minute, the heating cycle will not terminate until 1 minute after W1 became active. If the unit is controlled through a room thermostat set for fan auto, the indoor-fan motor will con- tinue to operate for an additional 45 seconds then stop. If the over-temperature limit opens after the indoor motor is stopped, but within 10 minutes of W1 becoming inactive, on the next cycle the time will be extended by 15 seconds. The maximum delay is 3 minutes. Once modified, the fan off delay will not change back to 45 seconds unless power is reset to the control. A LED indicator is provided on the IGC to monitor operation. Electro-mechanical Units with Factory-Installed EconoMi$er Cooling (Single Speed Indoor Fan Motor, Non-EnergyX units) Cooling — When free cooling is not available, the com- pressors will be controlled by the zone thermostat. When free cooling is available, the outdoor-air damper is modu- lated by the EconoMi$er IV and X control to provide a 50°F (10°C) to 55°F (13°C) mixed-air temperature into the zone. As the mixed air temperature fluctuates above 55°F (13°C) or below 50°F (10°C) dampers will be modulated (open or close) to bring the mixed-air temperature back within control. If mechanical cooling is utilized with free cooling, the outdoor-air damper will maintain its current position at the time the compressor is started. If the in- crease in cooling capacity causes the mixed-air tempera- ture to drop below 45°F (7°C), then the outdoor-air damp- er position will be decreased to the minimum position. If the mixed-air temperature continues to fall, the outdoor-air damper will close. Control returns to normal once the mixed-air temperature rises above 48°F (9°C). The power exhaust fans will be energized and de-energized, if in- stalled, as the outdoor-air damper opens and closes If field-installed accessory CO2 sensors are connected to the EconoMi$er IV and X control, a demand controlled ventilation strategy will begin to operate. As the CO2 level in the zone increases above the CO2 set-point, the mini- mum position of the damper will be increased proportion- ally. As the CO2 level decreases because of the increase in fresh air, the outdoor-air damper will be proportionally closed. For EconoMi$er IV and X operation, there must be a thermostat call for the fan (G). If the unit is occupied and the fan is on, the damper will operate at minimum posi- tion. Otherwise, the damper will be closed. When the EconoMi$er IV and X control is in the occupied mode and a call for cooling exists (Y1 on the thermostat), the control will first check for indoor fan operation. If the fan is not on, then cooling will not be activated. If the fan is on, then the control will open the EconoMi$er IV and X damper to the minimum position. On the initial power to the EconoMi$er IV and X control, it will take the damper up to 2 1/2 minutes before it begins to position itself. After the initial power-up, further changes in damper position can take up to 30 seconds to initiate. Controls 108 Damper movement from full closed to full open (or vice versa) will take between 1 1/2 and 2 1/2 minutes. If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or differential enthalpy), then the con- trol will modulate the dampers open to maintain the mixed- air temperature set-point at 50°F (10°C) to 55°F (13°C). If there is a further demand for cooling (cooling second stage — Y2 is energized), then the control will bring on compressor stage 1 to maintain the mixed-air temperature set-point. The EconoMi$er IV and X damper will be open at maximum position. 2-Speed Note: When operating in ventilation mode only, the indoor fan motor will automatically adjust to 66% of the total cfm established. Heating — The sequence of operation for the heating is the same as an electro-mechanical unit with no economiz- er. The only difference is how the economizer acts. The economizer will stay at the Economizer Minimum Position while the evaporator fan is operating. The outdoor-air damper is closed when the indoor fan is not operating. Refer to Service and Maintenance Manual for further de- tails. Optional Humidi-MiZer® dehumidification sys- tem — Units with the factory equipped Humidi-MiZer sys- tem option are capable of providing multiple modes of im- proved dehumidification as a variation of the normal cool- ing cycle. The Humidi-MiZer system option includes addi- tional valves in the liquid line and discharge line of each refrigerant circuit, a small reheat condenser coil down- stream of the evaporator, and Motormaster® variable- speed control of some or all outdoor fans. Operation of the revised refrigerant circuit for each mode is described be- low. The Humidi-MiZer system provides three sub-modes of op- eration: Cool, Reheat1, and Reheat2. Cool mode — Provides a normal ratio of Sensible and La- tent Cooling effect from the evaporator coil. Reheat1 — Provides increased Latent Cooling while slight- ly reducing the Sensible Cooling effect. Reheat2 — Provides normal Latent Cooling but with null or minimum Sensible Cooling effect delivered to the space. The Reheat1 and Reheat2 modes are available when the unit is not in a Heating mode and when the Low Ambient Lockout switch is closed. The figures on this page depict piping for single stage cooling units.

For more information regarding control- ler operation, see the EnergyX Start-Up, Operations, and Troubleshooting supplement manual. The EnergyX system will not activate unless the RTU fan is on. The EnergyX system default condition is to remain off in the unoccupied mode, however, this can be overridden via the control set points. Cooling operation — When the ComfortLink controller recognizes that the conditioned zone requires cooling (via the space temperature sensor or space thermostat) the En- ergyX module is activated. The EnergyX control module follows the sequence of operation logic as listed below. Step 1 — economizer operation — First, the EnergyX module checks if the outside air is suitable for free cooling via the outside air enthalpy sensor. If the outside air is suit- able for free cooling and the unit has an economizer, the EnergyX will operate in “ventilation mode” where the wheel will remain off but the ERV economizer will modu- late in free-cooling. If the unit is in Unoccupied mode, then the unit will not operate in economizer mode and will pro- ceed to Step 2. Step 2 — wheel operation — If the outside air is not suit- able for free cooling, then the EnergyX system will operate in either cooling or heating mode as called for by the roof- top unit ComfortLink controller. NOTE: If the unit is in Unoccupied mode, the default con- figuration is that the EnergyX module will not operate. This can be overridden by an adjustable setpoint in the En- ergyX controller. If the outside air is not suitable for free cooling then the En- ergyX wheel will activate and the supply fan will activate per the CFM setpoint. If a CO2 sensor is used (connected to the RTU Open or ComfortLink controller) the supply fan will modulate be- tween the DCV (Demand Controlled Ventilation) minimum and DCV maximum setpoints. The exhaust fan will modu- late to follow the supply fan operation per the Exhaust CFM-offset value. If the economizer opens more than 5%, the wheel utilizes a “stop-jog” operation to periodically ro- tate the wheel and minimize potential dirt build-up and ex- cess wear on one section of the wheel. NOTE: CO2 sensor requires a factory-installed economizer. Heating operation — When the ComfortLink controller sees that the space requires heating via the space tempera- ture sensor or when the thermostat or calls for heating, the EnergyX module is activated. The ERV wheel will rotate and the supply fan will activate per the CFM setpoint. If a CO2 sensor is used (connected to the RTU Open or ComfortLink controller) the supply fan will modulate be- tween the DCV minimum and DCV maximum setpoints. The exhaust fan will modulate to follow the supply fan op- eration per the Exhaust CFM-offset value, via the Econo- mizer Control Board (ECB). Supply and exhaust air frost control operation — When the factory-installed frost protection option is used, the EnergyX module will sense pressure differential across the energy recovery cassette. The supply blower will be shut off if the pressure differential across the energy recov- ery cassette exceeds the adjustable setpoint value. The blower will remain off for 5 minutes. The exhaust blower and wheel will remain on, in order to remove any frost build-up on the wheel. EnergyX filter maintenance indicator opera- tion — When the optional factory-installed filter mainte- nance indicator is used, a factory-installed differential pres- sure switch measures pressure drop across the outside air filter and activates a field-supplied dry contact indicator when the pressure differential exceeds the adjustable switch setpoint. EnergyX operation is not interrupted. 110 BASE UNIT APPLICATION DATA Minimum operating ambient temperature (cooling) — In mechanical cooling mode, your Carrier rooftop unit can safely operate down to an outdoor ambi- ent temperature of 35°F (–2°C). It is possible to provide cooling at lower outdoor ambient temperatures by using less outside air, economizers, and/or accessory low ambi- ent kits. Maximum operating ambient temp (cooling) — The maximum operating ambient temperature for cooling mode is 125°F (52°C). While cooling operation above 125°F (52°C) may be possible, it could cause either a re- duction in performance, reliability, or a protective action by the unit’s internal safety devices. Multiple motor and drive packages — Some applica- tions need larger horsepower motors, some need more air- flow, and some need both. Regardless of the case, your Carrier expert has a factory installed combination to meet your application. A wide selection of motors and pulleys (drives) are available, factory installed, to handle nearly any application. Stainless steel heat exchanger — The stainless steel heat exchanger option provides the tubular heat exchanger be made out of a minimum 20 gage type 409 stainless steel for applications where the mixed air to the heat ex- changer is expected to drop below 45°F (7°C). Stainless steel may be specified on applications where the presence of airborne contaminants require its use (applications such as paper mills) or in area with very high outdoor humidity that may result in severe in the heat exchanger during cool- ing operation. Minimum mixed air temperature (heating) — Using the factory settings, the minimum temperatures for the mixed air (the combined temperature of the warm return air and the cold outdoor air) entering the dimpled, gas heat exchangers are shown in the table below. MINIMUM TEMPERATURE FOR MIXED AIR TEMPERATURE Operating at lower mixed-air temperatures may be possi- ble, if a field-supplied, outdoor air thermostat initiates both heat stages when the temperature is less than the mini- mum temperatures listed above. Please contact your local Carrier representative for assistance. Minimum and maximum airflow (heating and cool- ing) — To maintain safe and reliable operation of your rooftop, operate within the heating airflow limits during heating mode and cooling airflow limits during cooling mode. Operating above the max may cause blow-off, un- desired airflow noise, or airflow related problems with the rooftop unit. Operating below the min may cause prob- lems with coil freeze-up and unsafe heating operation. Heating and cooling limitations differ when evaluating op- erating CFM, the minimum value is the HIGHER of the cooling and heating minimum CFM values published on page 7 and the maximum value is the LOWER of the cool- ing and heating minimum values published on page 7. Heating-to-cooling changeover — Your unit will auto- matically change from heating to cooling mode when using a thermostat with an auto-changeover feature. Airflow — All units are draw-though in cooling mode and blow-through in heating mode. Outdoor air application strategies — Economizers reduce operating expenses and compressor run time by providing a free source of cooling and a means of ventila- tion to match application changing needs. In fact, they should be considered for most applications. Also, consider the various economizer control methods and their benefits, as well as sensors required to accomplish your application goals. Please contact your local Carrier representative for assistance. Motor limits, break horsepower (BHP) — Due to in- ternal design of Carrier units, the air path, and specially de- signed motors, the full horsepower (maximum continuous BHP) band, as listed in the Fan Performance tables, can be used with the utmost confidence. There is no need for ex- tra safety factors, as Carrier motors are designed and rigor- ously tested to use the entire, listed BHP range without ei- ther nuisance tripping or premature motor failure. Propane heating — Propane has different physical quali- ties than natural gas. As a result, propane requires different fuel to air mixture. To optimize the fuel/air mixture for pro- pane, Carrier sells different burner orifices in an easy to in- stall accessory kit. To select the correct burner orifices or determine the heat capacity for a propane application, use either the selection software, or the unit’s service manual. High altitude heating — High altitudes have less oxy- gen, which affects the fuel/air mixture in heat exchangers. In order to maintain a proper fuel/air mixture, heat ex- changers operating in altitudes above 2000 ft (610 m) re- quire different orifices. To select the correct burner orifices or determine the heat capacity for a high altitude applica- tion, use either the selection software, or the unit’s service manual. High altitudes have less oxygen, which means heat ex- changers need less fuel. The new gas orifices in this field- installed kit make the necessary adjustment for high alti- tude applications. They restore the optimal fuel to air mix- ture and maintain healthy combustion on altitudes above 2000 ft (610 m). NOTE: Typical natural gas heating value ranges from 975 to 1050 Btu/ft3 at sea level nationally. The heating value goes down approximately 1.7% per every thousand feet el- evation. Standard factory orifices can typically be used up to 2000 ft (610 m) elevation without any operational is- sues. Sizing a rooftop — Bigger is not necessarily better. While an air conditioner needs to have enough capacity to meet the design loads, it does not need excess capacity. In fact, excess capacity typically results in very poor part load performance and humidity control. ALUMINIZED STAINLESS STEEL 50°F (10°C) Continuous 40°F (4°C) Continuous 45°F (7°C) Intermittent 35°F (2°C) Intermittent Application data 111 Using higher design temperatures than ASHRAE recom- mends for your location, adding “safety factors” to the cal- culated load, are all signs of oversizing air conditioners. Oversizing the air conditioner leads to poor humidity con- trol, reduced efficiency, higher utility bills, larger indoor temperature swings, excessive noise, and increased wear and tear on the air conditioner. Rather than oversizing an air conditioner, engineers should “right-size” or even slightly “under-size” air conditioners. Correctly sizing an air conditioner controls humidity better; promotes efficiency; reduces utility bills; extends equip- ment life, and maintains even, comfortable temperatures. Please contact your local Carrier representative for assis- tance. Low ambient applications — The optional Carrier economizer can adequately cool your space by bringing in fresh, cool outside air. In fact, when so equipped, accesso- ry low-ambient kit may not be necessary. In low ambient conditions, unless the outdoor air is excessively humid or contaminated, economizer-based “free cooling” is the pre- ferred less costly and energy conscious method. In low am- bient applications where outside air might not be desired (such as contaminated or excessively humid outdoor envi- ronments), your Carrier rooftop can operate to ambient temperatures down to –20°F (–29°C) using the recom- mended accessory Motormaster® low ambient controller. Staged air volume (SAV™) system with VFD controller (2-stage cooling models only) — Carrier’s staged air volume (SAV) system saves energy and installa- tion time by utilizing a variable frequency drive (VFD) to au- tomatically adjust the indoor fan motor speed in sequence with the units cooling operation. Per ASHRAE 90.1-2016 and IECC-2015, during the first stage of cooling operation the VFD will adjust the fan motor to provide two-thirds of the total cfm established for the unit. When a call for the second stage of cooling is required, the VFD will allow the total cfm for the unit established (100%). During the heat- ing mode the VFD will allow total design cfm (100%) oper- ation and during the ventilation mode the VFD will allow operation to two-thirds of total cfm. Compared to single speed indoor fan motor systems, Car- rier’s SAV system can save substantial energy, 25%+, ver- sus single speed indoor fan motor systems. The VFD used in Carrier’s SAV system has soft start capa- bilities to slowly ramp up the speeds, thus eliminating any high inrush air volume during initial start-up. It also has in- ternal over current protection for the fan motor and a field installed display kit that allows adjustment and in depth di- agnostics of the VFD. This SAV system is available on models with 2-stage cool- ing operation. The SAV system is very flexible for initial fan performance set up and adjustment. The standard factory shipped VFD is pre-programmed to automatically stage the fan speed between the first and second stage of cooling. The unit fan performance static pressure and cfm can be easily adjusted using the traditional means of pulley adjustments. The other means to adjust the unit static and cfm performance is to utilize the field-installed display kit and adjust the frequency and voltage in the VFD to required performance requirements. In either case, once set up, the VFD will automatically adjust the speed between the cooling stage operations. 48HC STAGED AIR VOLUME (SAV) — VARIABLE FREQUENCY DRIVE (VFD) HP RATING IMPORTANT: Data based on .10 ($/kWh) in an office application utilizing Carrier’s HAP 4.6 simulation soft- ware program. 48HC UNIT VOLTAGE STATIC OPTION VFD HP RATING 07 208/230, 460, 575 STD 3.0 208/230, 460 MED 3.0 575 MED 5.0 208/230, 460, 575 HIGH 7.5 08 208/230, 460, 575 STD 3.0 208/230, 460, 575 MED 3.0 208/230, 460, 575 HIGH 5.0 09 208/230, 460, 575 STD 3.0 208/230, 460, 575 MED 5.0 208/230, 460, 575 HIGH 3.0 11 208/230, 460, 575 STD 3.0 208/230, 460, 575 MED 5.0 208/230, 460, 575 HIGH 7.5 12 208/230, 460, 575 STD 3.0 208/230, 460, 575 MED 5.0 208/230, 460, 575 HIGH 7.5 14 208/230, 460 STD 3.0 575 STD 5.0 208/230, 460, 575 MED 5.0 208/230, 460, 575 HIGH 7.5 112 ENERGYX APPLICATION DATA ASHRAE 62.1 air classification requirements — The EnergyX® system allows for easy compliance with the current ASHRAE Standard 62.1 air classification require- ments. Pollutant transfer via Desiccant is a ‘non issue’ since by virtue of the ASHRAE “classes of air” the main determinant is EATR or cross transfer of air by leakage from exhaust to supply. Since the EATR is an AHRI Certi- fied measurement of an AHRI certified wheel device, the user can be assured of meeting the air dilution require- ments of ASHRAE 62.1 and therefore the air classification requirements. Industrial applications are by definition those that are Class 4 air (or worse). Most wheel manufacturers do not encour- age application of wheels to these types of applications. When required, many wheel manufacturers make specialty wheels with specific mechanical purge construction for in- dustrial applications, that can be used to field-replace the factory provided wheels. Contact the applicable wheel manufacture for specific application details. Choosing the proper airflow is essential. Unit selection guidance for the EnergyX system is in definite contrast to typical unit sizing and selections. Typical unit sizing meth- ods are to select the energy recovery device per the desired amount of outdoor air and then calculate the total capacity of the resulting energy recovery unit. This capacity is then subtracted from the desired total capacity for the condi- tioned zone. The remaining value is the necessary capacity of the rooftop unit. By conventional cooling and heating capacity guidance, the effort is to reduce the amount of outside (ventilation air) as much as possible since this addi- tional ventilation air results in increased load on the roof- top unit compressor and heating sections. NOTE: All units can be used in applications that require more or less airflow than the published CFM operating range as long as the airflow range is within the capabilities of the EnergyX fan system. This option can be used for high-static applications. Although performance is optimized at equal exhaust and supply airflow rates, the selection program and the Ener- gyX unit can be used with unequal airflow amounts. The unit must be sized for the largest airflow amount. The smaller airflow used cannot be less than 50% of the larger airflow in the published range. Energy recovery wheels — Carrier’s EnergyX energy recovery wheels consist of a welded stainless steel hub, spoke and rim assembly, which is independent of the heat transfer matrix. The heat transfer matrix is contained in patented energy transfer segments, removable from the wheel without requiring tools. The energy wheel uses a unique parallel plate geometry and polymer film substrate to provide an optimized heat exchanger design. The poly- mer film construction is not subject to corrosion in coastal locations or swimming pool areas. Silica gel technology — The EnergyX energy recovery wheels use the desiccant material known as silica gel, which is a highly porous solid adsorbent material that struc- turally resembles a rigid sponge. It has a very large internal surface composed of myriad microscopic cavities and a vast system of capillary channels that provide pathways connecting the internal microscopic cavities to the outside surface of the sponge. Silica gel enthalpy wheels transfer water by rotating between two air streams of different va- por pressures. The vapor pressure differential drives molecules into/from these cavities to transfer moisture from the more humid airstream to the drier airstream. Adsorption: silica gel vs. molecular sieve — The graph on page 113 shows the effect of Relative Humidity on Desic- cant Capacity characteristic curve for adsorption of water on silica gel. It shows the percent weight adsorbed versus relative humidity of the airstream in contact with the silica gel. The amount of water adsorbed rises linearly with in- creasing relative humidity (RH) until RH reaches near 60%. It then plateaus at above 40% adsorbed as relative humidity approaches 100%. For contrast, the curve for molecular sieves rises rapidly to plateau at about 20% absorbed at 20% RH. The Effect of Relative Humidity on Desiccant Capacity graph explains the following application considerations: • Molecular sieves are preferred for regenerated applica- tions such as desiccant cooling and dehumidification systems that must reduce the processed air streams to very low relative humidities. • Silica gel has superior characteristics for recovering space conditioning energy from exhaust air and han- dling high relative humidity outside conditions. The transfer of water by adsorption/desorption is not depen- dent on temperature. Therefore, the silica gel enthalpy wheel works to reduce latent load at difficult part-load conditions. Fungal growth and moisture transfer — Carrier EnergyX units have silica gel-based desiccant wheels. The water molecules are individually transferred by desorption/ad- sorption to and from the silica gel surfaces. Water is pres- ent on the wheel in a molecular layer only, and condensa- tion does not occur. Therefore, Carrier’s energy recovery wheels experience dry moisture transfer; there is no bulk liquid water present that could support fungal growth. Wa- ter transfer to and from the wheel’s desiccantsurfaces oc- curs in the vapor phase;there are no wet surfaces and liq- uid water does not enter the airstream. Silica gel is also highly selective for water, based on the strong preference MICROSCOPIC IMAGE OF SILICA GEL Application data (cont) 113 of the gel surface for the dipolar water molecule over other compounds. Frost control requirements — Energy recovery systems require frost protection or a means of defrosting in cli- mates that experience severe winter conditions. Frost for- mation results in a reduction and eventual blockage of air- flow through the energy wheel. Frost formation causes reduced airflow through the heat exchanger. Without frost control, energy recovery and air- flow may be significantly reduced. The frost threshold tem- perature is the point at which frost begins to ac- cumulate on heat exchanger surfaces. It is a function of both outside temperature and indoor relative humidity. The Frost Threshold Comparison figure compares the frost threshold of a plate-type sensible heat exchanger with that of an enthalpy wheel. Note that frost forms at tem- peratures between 22°F and 30°F in a plate-type heat ex- changer, frost threshold temperatures for enthalpy wheels are generally 20°F to 30°F degrees lower, approximately 0°F to 20°F. This is because the enthalpy wheel removes water from the exhaust air-stream, effectively lowering the exhaust’s dew point. The water removed is subsequently picked up through desorption by the entering outdoor air. Depending on the indoor relative humidity in areas where winter outside temperatures are between –5°F and 22°F, enthalpy wheel based recovery systems have a significant advantage over sensible plate type units because there is no additional cost for frost control. Even in cold areas, in most cases, enthalpy wheel based systems for schools and office buildings can be designed without frost control be- cause most of the frosting hours are at night when the building is unoccupied. Consult bin data, such as that pro- vided by ASHRAE, to qualify daytime applications in cold climates for frost-free operation. The Frost Thresholds Temperatures table lists typical frost threshold temperatures for Carrier’s EnergyX energy re- covery wheels over a wide range of indoor-air tempera- tures and relative humidity. Frost control is not required until outdoor air temperatures are below the threshold. In regions where winter temperatures are ex- treme, Carrier’s energy recovery wheels can be used effectively with the frost protection factory-installed op- tion (FIOP). NOTE: Refer to ASHRAE for bin data in cold climates where the threat of wheel frosting is frequent. Consult this information to ensure appropriate preheat techniques are used during occupied times. Frost prevention for frost control is required in extremely cold climates to preserve performance and assure the con- tinuous supply of outdoor air. Enthalpy wheel frost control strategies take advantage of inherently low frosting thresholds. This results in minimized energy use and maxi- mized design load reductions. In regions that experience extreme winter conditions, the frost protection FIOP al- lows the exhaust fan to operate below the frost threshold temperature; however, a temperature sensor would disable the supply fan when the outdoor-air temperatures reach the frost control set-point. The outdoor-air temperature sensor is located in the outdoor air intake of the ERV sec- tion. To avoid depressurization of the space, fresh air dampers may be required as part of the building’s ventila- tion system. Relative Humidity (%)Wt.

When properly designed (per ASHRAE standards), the economiz- er will control the amount of outdoor air allowed into the building and is integrated with the operation of the com- pressors. Carrier economizers are properly designed and allow free cooling to occur when the outdoor air is suitable depending upon the control strategy chosen. It has also been proven (by multiple independent sources) that using a demand controlled ventilation (CO2) strategy will result in considerable energy savings over a constant outdoor air volume strategy. This is because air to be brought in at a fixed rate has no variability as the outside air conditions change. Modulating EnergyX systems with DCV control allows the outside ventilation air to be re- duced to the minimum building ventilation requirements as required by the actual occupancy load, which in term re- duces the load on the unit compressors or heating system. It is recommended that an economizer option always be used with the EnergyX system. This allows for true free cooling operation when the outside air conditions allow for it. Wheel cleaning — The EnergyX system includes a 5-year wheel warranty as a standard product feature. Wheels are self cleaning from dry dust and dirt due to laminar airflow through the wheel. If volatile organic compounds (VOCs) are present, wheels need to be ‘deep’ cleaned just like evaporator coils must be in order to maintain latent recovery perfor- mance. Since it is easier and less risky to clean a wheel outside of the HVAC unit than within, EnergyX unit construc- tion allows for easy wheel segment removal. It is recommended that a different wheel segment be cleaned each time the unit air filters are changed in order to ensure periodic entire wheel cleaning. Wheel cleaning can be done simply and easily by hand. Proper wheel cleaning does not remove wheel desiccant. See the Ener- gyX Controls and Troubleshooting Supplement Instruc- tions for additional wheel cleaning and service information. Exhaust fan performance — Many applications that uti- lize energy recovery incorporate ducted return/exhaust air paths. In these applications, it is important to consider the duct pressure of the return/exhaust just as a de- signer would consider the effects of the supply duct static pressure on the airflow of the rooftop unit itself. EnergyX modulating volume 3 to 12.5 ton units — The exhaust fan in the Modulating Volume EnergyX unit will assist the rooftop unit fan in pulling air through the ex- haust/return duct. These exhaust fans are backwards curved impeller designs which are capable of significant more static pressure operation than typical forward curved fan designs. NOTE: If application designs require two separate ducts (one for exhaust air, one for return air) contact your Carrier Sales Engineer for additional guidance prior to specifica- tion or ordering.
