2. Above or below open-gridded type suspended ceilings.
3. With beams, joists, ducts, or other continuous obstruc-
tions located within the sprinkler coverage areas.
Beams, joists, or ducts may be located with their
centerlines along the boundaries separating adjacent
sprinkler coverage areas.
Cold Soldering Criteria.
With reference to Table A, the
Star Galaxy SG-RES must be located such that
1. The minimum lateral distance “C” between adjacent
sprinklers is 8 feet.
2. The minimum distance “D” between sprinklers located
opposite or with their waterway centerlines at 90° to
each other is 14 feet, except where a portion of the
dwelling structure or a partition will shield the spray of
one sprinkler from the other.
Heat Source Criteria.
Refer to NFPA 13D or NFPA 13R
for the requirements relating to preventing the possible re-
lease of a sprinkler heat responsive element (Bulb), due
to exposure to heat sources other than abnormal fire.
INSTALLATION
The Star Galaxy SG-RES must be installed in accord-
ance 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 with
an approximate diameter of 1/16 inch should be pre-
sent.
A leak tight 1/2 inch NPT sprinkler joint should be ob-
tained with a torque of 7 to 14 ft.lbs. (9,5 to 19,0 Nm).
A maximum of 21 ft.lbs. (28,5 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 adjust-
ment in an Escutcheon Plate by under- or over-tight-
ening the Sprinkler. Readjust the position of the sprin-
kler fitting to suit.
1. The sprinkler must only be installed with the centerline
of the waterway horizontal and perpendicular to the
backwall surface.
2. After installing the #2084 mounting plate (or other ac-
ceptable escutcheon, 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 a W-Type 9
Sprinkler Wrench (Ref. Figure 4) for horizontal sidewall
sprinkler installations or the W-Type 10 Wrench (Ref.
Figure 5) for recessed horizontal sidewall sprinkler instal-
lations. The wrench recess is to be applied to the sprin-
kler wrench flats (Ref. Figure 1). The word “TOP” on the
Deflector is to face towards the ceiling.
CARE AND MAINTENANCE
The Star Galaxy SG-RES must be maintained and serv-
iced 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,
