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 protec-
tors by undoing the clasp by hand. Do not use tools to remove
bulb protectors.
Model J112SS series sprinklers must be installed with the Re-
liable sprinkler installation wrench identified in this Bulletin.
Any other wrench may damage the sprinkler. Recommended
installation torque is 14 to 20 lb.ft (19 to 27 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.
Recessed pendent sprinklers are to be installed as shown in
Fig. 4 or Fig 5., as applicable to the specific model being in-
stalled. Model J112SS series recessed pendent sprinklers may
only be installed with the Reliable Model F1 or Model FP re-
cessed escutcheon. The use of any other recessed escutcheon
will void all approvals and negate all warranties. The Reliable
Model FP escutcheon may not be used in ceilings having pos-
itive pressure with respect to the space below. Ensure that the
openings in the Model FP escutcheon/can assembly are unob-
structed following installation.
Maintenance
Model J112SS 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 which has been painted (other than factory ap-
plied) 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.
