The glass bulb contains a uid which
expands when exposed to heat. When
the rated temperature is reached, the
uid expands sufciently to shatter the
glass bulb, allowing the sprinkler to acti-
vate and water to ow.

section.
General Instructions
Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1,6 mm for
the 57°C to 2,4 mm for the 141°C tem-
perature ratings.
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of
9 to 19 Nm. A leak tight 3/4 inch NPT
sprinkler joint should be obtained with
a torque of 13 to 27 Nm. Higher levels
of torque may distort the sprinkler inlet
and cause leakage or impairment of the
sprinkler.
