Installation
Model G series sprinklers must be installed with the Reliable Model
W2 sprinkler installation wrench as identified in this Bulletin. Any
other wrench may damage the sprinkler. The Model W2 wrench
has two sets of jaws. Use the smallest set of jaws that fit on the
wrench flats of the sprinkler. A leak tight sprinkler joint can be
obtained with an appropriate thread sealant and a torque of 6 to 12
lb-ft (8 to 16 N
.
m) for 3/8” threads, 8 to 18 lb-ft (11 to 24 N
.
m) for
1/2” threads, and 14 to 20 lb-ft (19 to 27 N
.
m) for 3/4” threads. Do
not tighten sprinklers over the maximum recommended installation
torque. Exceeding the maximum recommended installation torque
may cause leakage or impairment of the sprinkler.
Maintenance
Reliable Model G 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.
