Installation
Model F1 Series sprinklers must be installed in accordance with
NFPA13 and the requirements of all applicable authorities having
jurisdiction. Model F1 Series sprinklers must be installed with the
Reliable sprinkler installation wrench identified in this Bulletin. Any
other wrench may damage 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.

Maintenance
Reliable Model F1 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.
