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.
