Installation
The Model CC3 Sprinklers must be
installed in accordance with this
section.
General Instructions
The Model CC3 Sprinklers are to be
installed upright and with their frame
arms, see Figure 1, in-line with the
pipe run. See Figures 2 through 8, 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 200°F (93°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 CC3 Sprinklers must
only be installed in the upright posi-
tion with the deector parallel to the
upper deck. With pipe thread sealant
applied to the pipe threads, use only
the W-Type 6 (End A) Sprinkler Wrench,
see Figure 10, for installation of the
Model CC3 Sprinklers by applying the
wrench to the sprinkler wrench ats
only.
