Installation
The Series EC-8 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 3/4 in. NPT sprinkler joint
should be obtained with a torque of 10
to 20 lb-ft (13,4 to 26,8 N
·
m). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment of an escutch-
eon plate by under-or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Step 1.
The sprinkler must be installed
with the deflector parallel to the mount-
ing surface. Pendent sprinklers must
be installed in the pendent position.
Step 2.
After installing the Style 30 or
40 mounting plate (or other escutch-
eon, as applicable) over the sprinkler
pipe threads, and with pipe thread
sealant applied to the pipe threads,
hand tighten the sprinkler into the
sprinkler fitting.
Step 3.
Wrench tighten pendent sprin-
klers using only the W-Type 3 (End A)
Sprinkler Wrench. Wrench tighten the
recessed pendent sprinklers using only
the W-Type 23 Sprinkler Wrench. The
wrench recess of the applicable sprin-
kler wrench (Ref. Figures 4 and 5) is to
be applied to the sprinkler wrench flats
(Ref. Figure 1).
