Installation
The Series TY-B Sprinklers must be
installed in accordance with the follow-
ing instructions:
NOTES
Do not install any bulb type sprinkler if
the bulb is cracked or there is a loss of
liquid from the bulb. With the sprinkler
held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm) for the 135°F/57°C to 3/32
inch (2,4 mm) for the 360°F/182°C
temperature ratings.
A 1/2 inch NPT sprinkler joint should
be obtained with a minimum to maxi-
mum torque of 7 to 14 ft.lbs. (9,5 to
19,0 Nm). A 3/4 inch NPT sprinkler
joint should be obtained with a mini-
mum to maximum torque of 10 to 20
ft.lbs. (13,4 to 26,8 Nm). Higher levels
of torque may distort the sprinkler inlet
and cause leakage or impairment of
the sprinkler.
Do not attempt to make-up for insuffi-
cient adjustment in the escutcheon
plate by under- or over-tightening the
