Installation
The Series EC-5 Sprinklers must
be installed in accordance with this
section.
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 with a torque of 7 to
14 lb-ft (9,5 to 19,0 N
·
m). A maximum
of 21 lb-ft (28,5 N
·
m) of torque may be
used to install sprinklers with 1/2 NPT
connections. Higher levels of torque
may distort the sprinkler inlet and
cause leakage or impairment of the
sprinkler.
Do not attempt to make-up for insuf-
ficient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Readjust the position of the
sprinkler fitting to suit.
Series EC-5 Sidewall Sprinkler
The Series EC-5 Sidewall Sprinklers
must be installed in accordance with
the following instructions.
Step 1.
Horizontal sidewall sprinklers
are to be installed with their center-
line perpendicular to the back wall and
parallel to the ceiling. The word “TOP”
on the deflector is to face towards the
ceiling.
Step 2.
With pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 3.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
6 Sprinkler Wrench (Ref. Figure 3). With
reference to Figures 1, the W- Type 6
Sprinkler Wrench is to be applied to the
sprinkler wrench flats.
