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.
Model RFC30, RFC43 and RFC49 Residential
Concealed Sprinkler Specification
Sprinklers shall be cULus Listed low flow residential con-
cealed sprinklers with drop-down deflector and adjust-
able flat cover plate engineered for a minimum design
density of 0.05 gpm/ft2. Sprinkler frame and deflector
shall be of bronze frame construction having a ½” NPT
thread. Thermal element shall consist of an approved
black-painted beryllium-nickel fusible solder link with
symmetric lever mechanism, maintaining a Teflon-coated
Belleville spring washer and machined brass cap water
seal assembly containing no plastic parts. Sprinkler K-
factor shall be nominal 3.0 (43.2), 4.3 (62), and 4.9 (70.6)
having a 5
/
16”, 3
/
8” and 7
/
16” orifice. Temperature rating
shall be Ordinary 165°F (74°C); cover plate temperature
rating to be 135°F (57°C). Cover plate assembly shall
consist of a brass cover plate and copper alloy retainer
flange allowing a ½” cover plate adjustment. Any secure
engagement between the cover plate and the cup will
assure that the drop-down deflector is properly located
below the ceiling. A plastic protective cap shall be
provided and factory installed inside the sprinkler cup
to protect the drop-down sprinkler deflector from dam-
age, which could occur during construction before the
cover plate is installed. Standard cover finish: [Chrome]
[White] [Specialty – specify]. Residential concealed
sprinklers shall be Reliable Model RFC30, SIN RA0611
(Bulletin 006), Model RFC43, SIN RA0612 (Bulletin 006)
or Model RFC49, SIN RA0616 (Bulletin 006).
