Installation
The Model CC2 Sprinklers must be
installed in accordance with this
section.
General Instructions
The Model CC2 Sprinklers are to be
installed upright and with their frame
arms (Ref. Figure 1) in-line with the
pipe run (Ref. Figures 2 through 7, as
applicable).
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) for the 175°F (79°C) tempera-
ture rating.
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). Higher levels
of torque may distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler.
The Model CC2 Sprinklers must only
be installed in the upright position with
the deflector parallel to the upper deck.
With pipe thread sealant applied to the
pipe threads, use only the W-Type 6
(End A) Sprinkler Wrench (Ref. Figure
9) for installation of the Model CC2
Sprinklers by applying the wrench to
the sprinkler wrench flats only.
