Std. Response - Std. Coverage
Upright, Pendent, and
Recessed Pendent Sprinklers
Star Galaxy™ SG, K=8.0, 3/4" NPT
GENERAL DESCRIPTION
The Star Galaxy SG, 8.0 K-Factor, Upright, Pendent, and
Recessed Pendent Sprinklers are standard response -
standard coverage, decorative glass bulb type spray
sprinklers designed for use in light, ordinary, or extra haz-
ard, commercial occupancies such as banks, hotels,
shopping malls, factories, refineries, chemical plants, etc.
The recessed version of the Star Galaxy SG, intended for
use in areas with a finished ceiling, uses a two-piece
#2086 Recessed Escutcheon. The #2086 provides 1/2
inch (12,7 mm) of recessed adjustment or up to 3/4 inch
(19,1 mm) of total adjustment from the flush pendent posi-
tion. The adjustment provided by the Recessed Escutch-
eon reduces the accuracy to which the fixed pipe drops to
the sprinklers must be cut.
Wax and lead coatings are utilized to extend the life of
copper alloy sprinklers beyond that which would other-
wise be obtained when exposed to corrosive atmos-
pheres. Although wax and lead coated sprinklers have
passed the standard corrosion tests of the applicable ap-
proval agencies, the testing is not representative of all
possible corrosive atmospheres. Consequently, it is rec-
ommended that the end user be consulted with respect to
the suitability of these corrosion resistant coatings for any
given corrosive environment. The effects of ambient tem-
perature, concentration of chemicals, and gas/chemical
velocity, should be considered, as a minimum, along with
the corrosive nature of the chemical to which the sprin-
klers will be exposed.
An intermediate level version of the Star Galaxy SG Pen-
dent Sprinkler can be obtained by utilizing the Star Gal-
axy SG Pendent Sprinkler (SIN S2811) in combination
with the Model S11 Shield described in Product Data
Sheet 1-4.2.40.
WARNINGS
The Star Galaxy SG Sprinklers described herein must be
installed and maintained in compliance with this docu-
ment, as well as with the applicable standards of the Na-
tional Fire Protection Association, in addition to the stand-
ards of any other authorities having jurisdiction. Failure to
do so may impair the integrity of these devices.
The owner is responsible for maintaining their fire protec-
tion system and devices in proper operating condition.
The installing contractor or sprinkler manufacturer should
be contacted relative to any questions.
OPERATION
The glass bulb contains a fluid which expands when ex-
posed to heat. When the rated temperature is reached,
the fluid expands sufficiently to shatter the glass bulb,
which then allows the sprinkler to activate and flow water.

INSTALLATION
The 8.0 K-Factor, Star Galaxy Sprinklers must be in-
stalled in accordance with the following 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 3/32 inch
(2,4 mm) for the 360°F/182°C temperature ratings.
A leak tight 3/4 inch NPT sprinkler joint should be ob-
tainedwithatorqueof10to20ft.lbs.(13,4to20,4Nm).
A maximum of 30 ft. lbs. (40,7 Nm) of torque may be
used to install sprinklers with 3/4 NPT connections.
Higher levels of torque may distort the sprinkler inlet with
consequent leakage or impairment of the sprinkler.
Do not attempt to make-up for insufficient adjustment in
the escutcheon plate by under- or over-tightening the
sprinkler. Readjust the position of the sprinkler fitting to
suit.
The Star Galaxy SG Pendent and Upright Sprinklers
must be installed in accordance with the following instruc-
tions.
Step 1. Pendent sprinklers are to be installed on the pen-
dent position, and upright sprinklers are to be installed in
the upright position.
Step 2. With pipe thread sealant applied to the pipe
threads, hand tighten the sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the sprinkler fitting us-
ing only the W-Type 9 Sprinkler Wrench (Ref. Figure 3),
except that an 8 or 10 inch adjustable Crescent wrench is
to be used for wax coated sprinklers. With reference to
Figure 1, the W-Type 9 Sprinkler Wrench is to be applied
to the sprinkler wrenching area, and the adjustable Cres-
cent wrench is to be applied to the wrenching flanges.
When installing wax coated sprinklers with the adjustable
Crescent wrench, additional care needs to be exercised
to prevent damage to the wax coating on the sprinkler
wrenching flanges or frame arms and, consequently, ex-
posure of bare metal to the corrosive environment. The
jaws of the wrench should be opened sufficiently wide to
pass over the wrenching flanges without damaging the
wax coating. Before wrench tightening the sprinkler, the
jaws of the wrench are to be adjusted to just contact the
sprinkler wrenching flanges. After wrench tightening the
sprinkler, loosen the wrench jaws before removing the
wrench.
After installation, the sprinkler wrenching flanges and
frame arms must be inspected and the wax coating re-
touched (repaired) whenever the coating has been dam-
aged and bare metal is exposed. The wax coating on the
wrenching flanges can be retouched by gently applying a
heated 1/8 inch diameter steel rod to the areas of wax
that have been damaged, to smooth it back over areas
where bare metal is exposed.
NOTES
Only retouching of the wax coating applied to the wrench-
ing flanges and frame arms is permitted, and the retouch-

ing is to be performed only at the time of the initial sprin-
kler installation.
The steel rod should be heated only to the point at which
it can begin to melt the wax, and appropriate precautions
need to be taken, when handling the heated rod, in order
to prevent the installer from being burned.
If attempts to retouch the wax coating with complete cov-
erage are unsuccessful, additional wax can be ordered in
the form of a wax stick (the end of which is color coded).
Only the correct color coded wax is to be used, and re-
touching of wrenching flanges and frame arms is only per-
mitted at the time of initial sprinkler installation. With the
steel rod heated as previously described, touch the rod to
the area requiring additional wax with the rod angled
downward, and then touch the wax stick to the rod ap-
proximately one-half inch away from the area requiring re-
touching. The wax will melt and run down onto the sprin-
kler.
The Star Galaxy SG Recessed Pendent Sprinklers
must be installed in accordance with the following instruc-
tions.
Step A. After installing the #2086 Mounting Plate over
the sprinkler threads and with pipe thread sealant applied
to the pipe threads, hand tighten the sprinkler into the
sprinkler fitting.
Step B. Tighten the sprinkler into the sprinkler fitting us-
ing only the W-Type 10 Recessed Sprinkler Wrench (Ref.
Figure 3). With reference to Figure 1, the W-Type 10 Re-
cessed Sprinkler Wrench is to be applied to the sprinkler
wrenching flanges.
Step C. After the ceiling has been installed or the finish
coat has been applied, slide on the #2086 Closure over
the Star Galaxy SG Sprinkler and push the Closure over
the Mounting Plate until its flange comes in contact with
the ceiling.

CARE AND MAINTENANCE
The Star Galaxy SG Sprinklers must be maintained and
serviced in accordance with the following instructions:
NOTE
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.
Absence of an escutcheon, which is used to cover a clear-
ance hole, may delay the time to sprinkler operation in a
fire situation.
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 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 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).
Frequent visual inspections are recommended to be in-
itially performed for wax and/or lead coated sprinklers, af-
ter the installation has been completed, to verify the integ-
rity of the wax and/or lead coating. Thereafter, annual
inspections per NFPA 25 should suffice; however, instead
of inspecting from the floor level, a random sampling of
close-up visual inspections should be made, so as to bet-
ter determine the exact sprinkler condition and the long
term integrity of the wax and/or lead coating, as it may be
affected by the corrosive conditions present.
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.
