Installation
The TYCO Model WS Specific Appli-
cation Window Sprinklers 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).
A leak-tight 1/2 in. NPT sprinkler joint
should be obtained by applying a min-
imum-to-maximum torque of 7 to 14
ft-lb (9,5 to 19,0 N
∙
m). Higher levels of
torque may distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler.
Step 1.
Install the pendent vertical
sidewall sprinkler only in the pendent
position with the center-line of the
sprinkler parallel to the glass surface.
Orient the sprinkler so that the direc-
tion of flow indicated on the sprinkler
deflector is facing the window.
Step 2.
Install the horizontal sidewall
sprinkler only in the horizontal position
with the center-line of the sprinkler per-
pendicular to the glass surface. Orient
the sprinkler so that the word “Top”
indicated on the sprinkler deflector is
facing the top of window frame.
Step 3.
With pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 4.
With reference to Figures 1 or
2, apply End A of W-Type 20 Sprinkler
Wrench only (Figure 4) to the sprinkler
wrench flats and tighten the sprinkler
into the sprinkler fitting.
