Listed by Underwriters Laboratories, and certified by UL for Canada (cULus) UL Listing Categories Residential Automatic Sprinklers UL Guide Number VKKW Product Description Model RFC30, RFC43 and RFC49 Concealed Residen- tial Sprinklers are fast response residential fusible solder link automatic sprinklers. Residential sprinklers differ from standard sprinklers primarily in their response time and water distribution patterns. Model RFC30, RFC43 and RFC49 sprinklers discharge water in a hemispherical pattern below the sprinkler de- flector. Residential distribution patterns are higher and generally contain a finer droplet size than standard sprin- kler patterns. The combination of speed of operation and high dis- charge pattern required for residential sprinklers has demonstrated, in fire testing, an ability for controlling residential fires, and thereby providing significant evacu- ation time for occupants. The RFC30, RFC43 and RFC49 Sprinklers provide the best form of fire protection by combining an attractive ap- pearance and ½” (13mm) of cover adjustment for ease of installation. The small diameter cover plate is easily and positively attached and blends into the ceiling, con- cealing the most dependable fire protection available, an automatic sprinkler system. The RFC30, RFC43 and RFC49 are UL Listed Residen- tial Sprinklers to be installed in the residential portions of any occupancy in accordance with NFPA 13, 13R, & 13D. The RFC30, RFC43 and RFC49 can reduce the need for precise cutting of drop nipples. The threaded cover plate assembly can be adjusted without tools to fit ac- curately against the ceiling. The fire protection system need not be shut down to adjust or remove the cover plate assembly. Plain Cover Plate Perforated Cover Plate 2. Application and Installation The RFC30, RFC43 and RFC49, for residential instal- lations, use a 165°F (74°C) fusible solder link in a tun- ing fork style sprinkler frame with a drop-down deflector. This assembly is recessed into the ceiling and concealed by a flat cover plate. The cover plate is attached to the skirt, using 135°F (57°C) ordinary temperature classifica- tion solder. When the ceiling temperature rises, the solder holding the cover plate releases the cover allowing the deflector to drop into position and exposing the sprinkler inside to ceiling temperature. The subsequent operation of the solder link opens the waterway and causes the de- flector to drop into position to distribute the discharging water in a hemispherical pattern below the sprinkler de- flector. Any adjustment of thread engagement between the cover plate and cup will assure that the drop-down deflector is properly located below the ceiling. The resi- dential distribution pattern contains a finer droplet size than a standard sprinkler, and the pattern produces sig- nificantly higher wall wetting. After a 25/8 inch diameter hole is cut in the ceiling, the sprinkler is to be installed with the Model FC Wrench. When installing a sprinkler, the wrench is first positioned into the sprinkler/cup assembly and around the hexago- nal body of the sprinkler frame. The Wrench must bottom out against the cup in order to ensure proper, safe instal- lation. The sprinkler is then tightened into the pipe fitting. When inserting or removing the wrench from the sprin- kler/cup assembly, care should be taken to prevent dam- age to the sprinkler. DO NOT WRENCH ON ANY OTHER PART OF THE SPRINKLER/CUP ASSEMBLY. MODEL RFC30, RFC43 AND RFC49 CONCEALED SPRINKLERS MUST BE INSTALLED ONLY WITH 135°F RATED COV- ERS. Note: A leak tight ½” NPT (R1/2) sprinkler joint can be ob- tained with a torque of 8-18 ft-lbs (10,8 - 24,4 N-m). Do not tighten sprinklers over maximum recommended torque. It may cause leakage or impairment of the sprinklers. Cover assemblies provide up to 1/2” (13mm) of adjust- ment. Turn the cover clockwise until the flange is in con- tact with the ceiling. For the push-on/thread-off option, the cover assembly is pushed onto the cup and final ad- justment is made by turning the cover clockwise until the skirt flange makes full contact with the ceiling. Cover re- moval requires turning in the counter-clockwise direction. In ceilings that have a plenum space above the sprinkler, the plenum space may have neutral or neg- ative pressurization but must not be positively pres- surized. Inspect all sprinklers after installation to en- sure that the gap between the cover plate and ceiling and the 4 slots in the cup are all open and free from any air ﬂ ow impediment.

Maintenance Model RFC30, RFC43 and RFC49 Concealed Sprin- klers should be inspected and the sprinkler system maintained in accordance with NFPA 25. Do not clean sprinklers with soap and water, ammonia or any other cleaning fluids. Remove dust by using a soft brush or gentle vacuuming. Remove any sprinkler cover plate as- sembly which has been painted (other than factory ap- plied) or damaged in any way. A stock of spare sprin- klers should be maintained to allow quick replacement of damaged or operated sprinklers. Prior to installation, sprinklers should be maintained in the original cartons and packaging until used to minimize the potential for damage to sprinklers that would cause improper opera- tion or non-operation.
