INSTALLATION
The Luminous S176 must be installed in accordance with
the following instructions:
NOTES
The Luminous S176 must only be installed in fittings that
meet the requirements of the Design Criteria section.
Refer to the Design Criteria section for other important re-
quirements regarding sealing of the clearance space
around the Sprinkler Casing.
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 rating to 1/8 inch
(3,2 mm) for the 360°F/182°C rating.
A leak tight 1 inch NPT sprinkler joint should be obtained
with a torque of 20 to 30 ft.lbs. (26,8 to 40,2 Nm). Higher
levels of torque may distort the sprinkler inlet with conse-
quent 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 horizontal po-
sition, and the word “TOP” on the deflector must face up-
wards toward the ceiling.
2. With pipe thread sealant applied to the pipe threads,
hand tighten the sprinkler into the sprinkler fitting.
3. Wrench tighten the sprinkler by wrenching on the Cas-
ing with a pipe wrench whenever the casing is readily ac-
cessible. Otherwise, use a W-Type 7 Sprinkler Wrench
(Ref. Figure 3). The wrench recess of the W-Type 7 is to
be applied to the sprinkler wrench flats (Ref. Figure 1).
4. After the wall construction is completed or the finish coat
has been applied to the wall (as applicable), slide on the
outer piece of the Escutcheon until it comes in contact with
the wall (Ref Figure 4).
