Installation
The TYCO Model LD, 11.2 K-factor
Large Drop Upright Sprinkler, Stan-
dard Response Control Mode Specific
Application must be installed in accor-
dance 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. The diameter of
the air bubble is approximately 1/16
in. (1,6 mm) for the 155°F (68°C) rating
and 3/32 in. (2,4 mm) for the 286°F
(141°C) rating.
A leak tight 3/4 in. NPT sprinkler joint
should be obtained by applying a min-
imum-to-maximum torque of 7 to 20
lb-ft (13,4 to 26,8 N
∙
m). Higher levels
of torque can distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler.
Step 1.
With pipe thread sealant
applied to the pipe threads, hand
tighten the Model LD Sprinkler into the
sprinkler fitting.
Step 2.
Using the W-Type 3 (End
B) Sprinkler Wrench (Ref. Figure 2)
applied to the sprinkler Wrench Flats
(Ref. Figure 1), tighten the Model LD
Sprinkler into the sprinkler fitting.
