CARE AND MAINTENANCE
The Star Galaxy SG-R must be maintained and serviced
in accordance with the following instructions:
NOTES
Wet pipe sprinkler systems must be maintained at a
minimum temperature of 40°F/4°C to prevent freezing
and bursting of the pipe and/or sprinklers.
Automatic sprinklers are not to be tested with a heat
source. Operation of the heat responsive element
(bulb) can result.
Absence of an Escutcheon Plate may delay the time
to sprinkler operation in a fire situation.
Before closing a fire protection system main control
valve for maintenance work on the fire protection sys-
tem which it controls, permission to shut down the af-
fected fire protection system must be obtained from
the proper authorities and all personnel who may be
affected by this action must be notified.
Do NOT enclose sprinklers within drapes, curtains, or
valances.
Do NOT hang anything from the sprinklers.
Do NOT cleanse the sprinklers with soap and water,
detergents, ammonia, cleaning fluids, or other chemi-
cals. Remove dust, lint, cobwebs, cocoons, insects,
and larvae by gently brushing with a feather duster or
gently vacuuming with a soft bristle (i.e., dusting)
brush attachment.
Exercise suitable safety precautions in the use and
storage of highly flammable materials. The rapid rate
of fire development and spread of which can be
caused by such materials can reduce the ability of
the sprinkler system to aid in the control of a fire in
which they are involved.
The minimum vertical clearance between the tops of
free standing partitions, room dividers, cabinets, stor-
age racks, stock piles, etc., and the sprinkler deflec-
tor is NOT to be less than the clearance given in Table
B.
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 its temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered 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 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 - both before
and after installation. Sprinklers damaged by dropping,
striking, wrench twist/slippage, or the like, must be re-
placed. Also, replace any sprinkler that has a cracked
bulb or that has lost liquid from its bulb (Ref. Installation
Section).
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.
The Star Galaxy SG-R must only be replaced with pen-
dent sprinklers which are listed for residential fire protec-
tion service and which have the same nominal K-factor,
the same coverage area, and the same or lower flow rat-
ings (as indicated under “Hydraulic Design Criteria”).
When remodeling, such as by adding false beams or light
fixtures or changing the location of compartment walls,
first verify that the new construction will not violate the in-
stallation requirements stated under WARNINGS. Alter
the new construction and/or the sprinkler system to suit
the requirements of this document.
