Maintenance
Model F1FR-SS series sprinklers should be inspected and

Do not clean sprinklers with soap and water, ammonia or any
other cleaning fluids. Remove dust by gentle vacuuming. Re-
place any sprinkler 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.

Installation
Glass bulb sprinklers have orange bulb protectors to minimize
bulb damage during shipping, handling, and installation. Re-
liable sprinkler installation wrenches are designed to install
sprinklers with bulb protectors in place. Remove the bulb pro-
tector at the time when the sprinkler system is placed in service
for fire protection. Removal of the bulb protector before this
time may leave the bulb vulnerable to damage. Remove bulb
protectors by undoing the clasp by hand. Do not use tools to
remove bulb protectors.
Model F1FR-SS series sprinklers must be installed with the
Reliable sprinkler installation wrench identified in this Bulletin.
Any other wrench may damage the sprinkler. Recommended
installation torque is 8 to 18 lb/ft (11 to 24 N/m) for 1/2” NPT and
ISO7-1R1/2 sprinklers or 14 to 20 lb/ft (19 to 27 N/m) for 3/4”
NPT and ISO7-1R3/4 sprinklers. Do not tighten sprinklers over
the maximum recommended installation torque. Exceeding the
maximum recommended installation torque may cause leak-
age or impairment of the sprinkler.
Recessed pendent sprinklers are to be installed as shown in
Fig. 2 or Fig 5., as applicable to the specific model being in-
stalled. Model F1FR-SS series recessed pendent sprinklers
may only be installed with the Reliable Model F1 stainless steel
or Model FP stainless steel recessed escutcheon. The use of
any other recessed escutcheon will void all approvals and ne-
gate all warranties. The Reliable Model FP escutcheon may not
be used in ceilings having positive pressure with respect to
the space below. Ensure that the openings in the Model FP es-
cutcheon/can assembly are unobstructed following installation.
Application
Model F1FR-SS series sprinklers are standard spray, quick-re-
sponse sprinklers intended for installation in accordance with
NFPA 13 and the requirements of applicable Authorities Having
Jurisdiction. Model F1FR-SS series sprinklers are cULus Listed
as Corrosion Resistant sprinklers. Verify compatibility with the
environment where the sprinkler will be located prior to instal-
lation.
