Maintenance
Reliable Model F1XLH and F1FRXLH 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.

Installation
Model F1XLH and F1FRXLH Series sprinklers must be installed
with the Reliable sprinkler installation wrench 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 on 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.
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.
