Product Description
Model RFC Series residential sprinklers are flat cover plate,
concealed pendent sprinklers intended for installation in
accordance with NFPA 13, NFPA 13R, or NFPA 13D. The
sprinklers are cULus Listed as Residential Sprinklers in accordance with UL 1626. In addition, Model RFCLL Series
sprinklers are cULus Certified for Health Effects to NSF/ANSI
standard 61 Annex G (LL) and Australian WaterMark Certified
(WMCS).

Model RFC30 sprinklers have a 165°F (74°C) temperature
rated fusible-link operating element. Model RFC43, RFC49,
RFC58, and RFC76 sprinklers are offered with either a 165°F
(74°C) or 212°F (100°C) temperature rated fusible-link operating element. Sprinklers with a 165°F (74°C) temperature
Model RFC49 & RFC49LL Model RFC58
rating are ordinary temperature classification and are listed
for use with a 135°F (57°C) temperature rated cover plate.
Sprinklers with a 212°F (100°C) temperature rating are intermediate temperature classification and are listed for use with
a 165°F (74°C) temperature rated cover plate.
Model RFC Series sprinklers are installed with a Model RFC
cover plate. Model RFC cover plates may be installed by either pushing or threading the cover plate into the sprinkler
cup. Model RFC30, RFC30LL, RFC43, RFC43LL, RFC49 and
RFC49LL sprinklers allow 1/2” (13 mm) of cover plate adjustment. Model RFC58 and RFC76 sprinklers allow 3/4” (19 mm)
of cover plate adjustment. Model RFC cover plates are avail-
Model RFC76
able in a variety of finishes as listed in Table H.

prior to installation. A 1/2” x 1/2” brass nipple extension (Reliable P/N 6999991900) is available where necessary for replacement of existing
sprinklers.
2. For use with 165°F (74°C) temperature rated sprinklers where the Maximum Ceiling Temperature does not exceed 100°F (38°C).
3. For use with 212°F (100°C) temperature rated sprinklers where the Maximum Ceiling Temperature does not exceed 150°F (66°C).
Installation
Model RFC series sprinklers are intended to be installed in accordance with NFPA 13, NFPA 13R, or NFPA 13D, as well as the
requirements of applicable authorities having jurisdiction. Model RFC series sprinklers must not be installed in ceilings with
positive pressure in the space above. Ensure that the 4 slots in
the cup are open and unobstructed following installation. Model
RFC series sprinklers are shipped with a wrench-able protective cap that should remain on the sprinkler until the sprinkler
system is placed in service following construction.
Model RFC series sprinklers can be installed without removing
the wrench-able protective cap using the Model W3 wrench.
Alternatively, Model RFC series sprinklers can be installed using the Model FC wrench by temporarily removing the protective cap during installation of the sprinkler. The use of any other
wrench to installed Model RFC series sprinklers is not permitted and may damage the sprinkler. Fully insert the Model W3
wrench over the cap until it reaches the bottom of the cup, or
the Model FC wrench over the sprinkler until the wrench engages the body. Do not wrench any other part of the sprinkler/cup
assembly. The Model W3 and FC wrenches are designed to be
turned with a standard 1/2” square drive. Tighten the sprinkler
into the fitting after applying a PTFE based thread sealant to the
sprinkler’s threads. Recommended installation torque is 8 to 18
ft-lbs (11 to 24 N-m) for 1/2” thread sprinklers and 14 to 20 ft-lbs
(19 to 27 N-m) for 3/4” thread sprinklers.
Bulletin 006
May 2019
Do not exceed the maximum recommended torque. Exceeding
the maximum recommended torque may cause leakage or impairment of the sprinkler. Use care when inserting or removing
the wrench from the sprinkler to avoid damage to the sprinkler.
Install the cover plate by hand by pushing the cover plate into
the cup and turning the cover in the clockwise direction until it
is tight against the ceiling.
Application
Model RFC series sprinklers are intended for installation where
residential sprinklers are permitted or required by NFPA 13,
NFPA 13R, and NFPA 13D. The sprinklers are concealed pendent residential sprinklers.
Model RFC 30 and RFC30LL sprinklers are available in ordinary
temperature classification for installation where the Maximum
Ceiling Temperature does not exceed 100°F (38°C). Model
RFC43, RFC43LL, RFC49, RFC49LL, RFC58, and RFC76 sprinklers are available in either ordinary or intermediate temperature classification for installation where the Maximum Ceiling
Temperature does not exceed 100°F (38°C) or 150°F (66°C),
respectively.

Maintenance
Model RFC series sprinklers 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 gentle vacuuming. Replace
any sprinkler cover plate assembly which has been painted
(other than factory applied) or damaged in any way. A stock of
spare sprinklers 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 operation or non-operation.
