Maintenance
Model F1-SS series sprinklers should be inspected and the sprin-
kler 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
which has been painted (other than factory applied) or damaged
in any way. A stock of spare sprinklers should be maintained to al-
low 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. Reliable sprin-
kler installation wrenches are designed to install sprinklers with bulb
protectors in place. Remove the bulb protector at the time when the
sprinkler system is placed in service for re 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 F1-SS series sprinklers must be installed with the Reliable sprin-
kler installation wrench identied 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 leakage or impairment of the sprinkler.
Recessed pendent sprinklers are to be installed as shown in Fig. 5.
Model F1-SS series recessed pendent sprinklers may only be installed
with the Reliable Model F1 stainless steel, Model F2 Stainless Steel, or
Model FP stainless steel recessed escutcheon. The use of any other
recessed escutcheon will void all approvals and negate all warranties.
Application
Model F1-SS series sprinklers are standard spray, standard-re-
sponse sprinklers intended for installation in accordance with
NFPA 13 and the requirements of applicable Authorities Having
Jurisdiction. Model F1-SS series sprinklers are cULus Listed and
FM Approved as Corrosion Resistant sprinklers. Verify compatibili-
ty with the environment where the sprinkler will be located prior to
installation.
