INSTALLATION
The SG S180 must be installed in accordance with the fol-
lowing instructions:
NOTES
Do not install any bulb type sprinkler if the bulb is
cracked or there is a loss of liquid from the bulb. With the
sprinkler held horizontally, a small air bubble should be
present. The diameter of the air bubble is approximately
1/16 inch (1,6 mm) for the 135°F/57°C to 200°F/93°C tem-
perature ratings.
A leak tight 3/4 inch NPT sprinkler joint should be ob-
tained with a torque of 10 to 20 ft.lbs. (13,4 to 26,8 Nm).
A maximum of 30 ft.lbs. (40,7 Nm) of torque is to be used
to install sprinklers. Higher levels of torque may distort
the sprinkler inlet with consequent leakage or impairment
of the sprinkler.
Do not attempt to compensate for insufficient adjustment
in an Escutcheon Plate by under- or over-tightening the
Sprinkler. Readjust the position of the sprinkler fitting to
suit.
1. The sprinkler must be installed only in the pendent posi-
tion and with the deflector parallel to the mounting sur-
face.
2. After installing the #2086 mounting plate (or other es-
cutcheon, 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.
3. Wrench tighten the Sprinkler using only the W-Type 9
or W-Type 10 Sprinkler Wrench (Ref. Figure 3). The
wrench recess of the W-Type 9 or W-Type 10 is to be
applied to the sprinkler wrenching area (Ref. Figure 1).
The W-Type 10 is principally used for recessed installa-
tions where the sprinkler wrenching area is otherwise in-
accessible.
