Maintenance
Reliable Model GQR112 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.
