Installation
Model F1FR Series sprinklers must be installed with the
W2 (pendent) or W4 (recessed pendent) Reliable sprinkler
installation wrench as identified in this Bulletin. Any other wrench
may damage the sprinkler. The Models W2 and W4 wrenches
have two sets of jaws. Use the smallest set of jaws that fit the
wrench flats of the sprinkler. A leak tight sprinkler joint can be
obtained with a torque of 8 to 18 lb-ft (11 to 24 N-m). Do not
tighten sprinklers over the maximum recommended installation
torque. Exceeding the maximum recommended installation
torque may cause leakage or impairment of the sprinkler.
Both the Model W2 and W4 wrench have two sets of jaws.
Use the smallest set of jaws that fit on the wrench flats of the
sprinkler. The Model W4 wrench is used in conjunction with
a nominal 1/2” square drive ratchet with a nominal 5” long
extension (not provided).
Glass bulb sprinklers have orange bulb protectors or protective
caps to minimize bulb damage during shipping, handling
and installation. Reliable sprinkler 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 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.

Sprinkler and Escutcheon Finishes(1)(2) Table B
Maintenance
Reliable Model F1FR series sprinklers should be inspected
and the sprinkler system maintained in accordance with NFPA
25, as well as the requirements of any Authorities Having
Jurisdiction.
Prior to installation, sprinklers should remain in the original
cartons and packaging until used. This will minimize the
potential for damage to sprinklers that could cause improper
operation or non-operation.
Do not clean sprinklers with soap and water, ammonia
liquid or any other cleaning fluids. Remove dust by gentle
vacuuming without touching the sprinkler.
Replace any sprinkler which has been painted (other than
factory applied). A stock of spare sprinklers should be
maintained to allow quick replacement of damaged or
operated sprinklers. Failure to properly maintain sprinklers
may result in inadvertent operation or non-operation during a
fire event.
