Automatic sprinklers must never be shipped or stored
where its temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered after leaving the factory. Modified sprinklers must
be replaced. Sprinklers that have been exposed to corro-
sive products of combustion, but have not operated,
should be completely cleaned by wiping the sprinkler with
a cloth or by brushing it with a soft bristle brush.
Care must be exercised to avoid damage - before, dur-
ing, and after installation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage, or the like, must be
replaced. Also, replace any sprinkler that has a cracked
bulb or that has lost liquid from its bulb (Ref. Installation
Section).
The owner is responsible for the inspection, testing, and
maintenance of their fire protection system and devices in

It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.

dent sprinklers which are listed for residential fire protec-
