A Vent Hole is provided in the Bulb Seat
to indicate if the Dry Sprinkler is remain-
ing dry. (Refer to Figures 1 through 3.)
Evidence of leakage from the Vent
Hole indicates potential leakage past
the Inlet seal and the need to remove
the sprinkler to determine the cause
of leakage; for example, an improper
installation or an ice plug. Close the
fire protection system control valve and
drain the system before removing the
sprinkler.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.

liquid from its bulb. (Refer to Installa-
tion Section.)
