INSTALLATION
The Luminous S170 must be installed in accordance with
the following instructions:
NOTES
The Luminous S170 must only be installed in fittings that
meet the requirements of the Design Criteria 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
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.
1. The sprinkler must be installed only in the upright posi-
tion.
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.
CARE AND MAINTENANCE
The Luminous S170 must be maintained and serviced in
accordance with the following instructions:
NOTES
Before closing a fire protection system main control valve
for maintenance work on the fire protection system which
it controls, permission to shut down the affected fire pro-
tection systems must be obtained from the proper authori-
ties and all personnel who may be affected by this action
must be notified.
It is recommended that the piping connected to Dry Sprin-
klers be periodically checked to assure that proper pitch
and drainage is in accordance with the minimum require-
ments of the National Fire Protection Association if the
piping is subject to freezing temperatures.
A Vent Hole is provided in the Bulb Seat (Ref. Figure 2)
to indicate if the Dry Sprinkler is remaining dry. Evidence
of leakage from the Vent Hole is an indication that there
may be weepage past the O-ring seal and, therefore, it is
an indication that the sprinkler needs to be removed for
determining the cause of leakage (e.g. an improper instal-
lation or an ice plug). The fire protection system control
valve must be closed and the system drained before re-
moving the sprinkler.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperatures will exceed 100°F/38°C and
they must never be painted, plated, coated or otherwise
altered after leaving the factory. Modified sprinklers must
be replaced. Sprinklers that have been exposed to corro-
sive products of combustion, but have not operated,
should be replaced if they cannot be completely cleaned
by wiping the sprinkler with a cloth or by brushing it with a
soft bristle brush.
Care must be exercised to avoid damage to the sprinklers
— before, during, and after installation. Sprinklers dam-
aged by dropping, striking, wrench twist/slippage, or the
like, must be replaced. Also, replace any sprinkler that
has a cracked bulb or that has lost liquid from its bulb.
(ref. Installation Section Note).
The owner is responsible for the inspection, testing, and
maintenance of their fire protection system and devices in
compliance with this document, as well as with the appli-
cable standards of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the standards of any
other authorities having jurisdiction. The installing contrac-
tor or sprinkler manufacturer should be contacted relative
to any questions.
It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.
