Maintenance
Reliable Model LT56 series sprinklers should be inspected and
the sprinkler system maintained in accordance with NFPA 25,
as well as the requirements of any Authorities Having Jurisdic-
tion.
Prior to installation, sprinklers should remain in the original car-
tons 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 facto-
ry applied). Properly installed Model CCP and Model G4 cover
plates will have an air gap that is required for proper operation,
do not seal the gap or paint the cover plates. Model FV and FP
escutcheons as well as Model CCP and Model G4 cover plates
have holes in the ring or cup that must remain unobstructed.
Replace any sprinkler which has been damaged, cracked the
glass bulb, or has lost liquid from the glass bulb. A stock of
spare sprinklers should be maintained to allow quick replace-
ment of damaged or operated sprinklers.
Failure to properly maintain sprinklers may result in inadvertent
operation or non-operation during a fire event.
