Installation
The TYCO Series TY-B, 5.6 K-factor,
Conventional Sprinklers (TY365) must
be installed in accordance with this
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 1/16 in.
(1,6 mm) for the 135°F (57°C) to 3/32 in.
(2,4 mm) for the 360°F (182°C) tempera-
ture ratings.
A leak tight 1/2 in. NPT sprinkler joint
should be obtained with a torque of 7 to
14 lb-ft (9,5 to 19,0 N∙m). Higher levels
of torque may distort the sprinkler inlet
and cause leakage or impairment of the
sprinkler.
Step 1. With pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 2. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 6
Sprinkler Wrench (Figure 2), except that
an 8 in. or 10 in. adjustable Crescent
wrench is to be used for wax coated
sprinklers. With reference to Figure 1,
the W-Type 6 Sprinkler Wrench or the
Crescent wrench, as applicable, is to
be applied to the wrench flats.
