Operation
When the glass bulb reaches its rated
temperature of 155°F (68°C), 200°F
(93°C), or 286°F (141°C) the glass bulb
bursts allowing the sprinkler to activate
and flow water.
Installation
Install the TYCO Model TY7158 Stan-
dard Coverage Upright Sprinkler 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 horizontal, a small air bubble
should be present. For the Model
TY7158 Sprinkler, the diameter of the
air bubble is approximately 1/16 inch
(1,6 mm).
A leak tight 3/4 inch NPT sprinkler joint
should be obtained by applying a min-
imum-to-maximum torque or 10 to 20
ft.-lbs. (13,4 to 26,8 Nm). Higher levels
of torque may distort the sprinkler inlet
with consequent leakage or impair-
ment of the sprinkler. Only the W-type
8 Sprinkler Wrench (Ref. Figure 2) shall
be used during installation.
Sprinkler Installation
Install the Model TY7158 Upright Sprin-
kler only in the upright position as
follows:
Step 1. Apply pipe-thread sealant to
sprinkler threads.
