Cautions must be understood by all dis-
ciplines (for example, sprinkler fitters,
designers, authorities having jurisdic-
tion, and material handlers) involved
with the installation of automatic sprin-
klers. Care must be exercised during
installation, and the following guide-
lines must be followed to ensure that
the sprinkler will operate properly:
• Store sprinklers properly and shield
them from extreme heat. Do not
store sprinklers in direct sunlight or
in areas of vehicles that are subject.
to extreme temperatures. Over-
heating will damage the sprinkler
by weakening the thermal sens-
ing element resulting in premature
activation.
• Sprinkler cartons are specially
designed to protect the sprinkler
during transit. Do not empty sprin-
klers from their cartons into bags or
buckets prior to installation, since
damage to the sprinklers may result.
Install the sprinklers directly from
their cartons.
• Unless otherwise modified by
NATIONAL FIRE PROTECTION
STANDARDS (NFPA) such as
NFPA 13 “Installation of Sprin-
kler Systems”, sprinkler temper-
ature ratings shall be as follows:

TABLE A
TEMPERATURE
RATINGS
Over-heating will damage the sprin-
kler by weakening the thermal sens-
ing element resulting in premature
activation.
• Do not install any sprinkler that
shows signs of damage. Immediately
replace all sprinklers that are dam-
aged during installation.
• Inspect glass bulb sprinklers at the
time of installation to make sure that
the bulb contains fluid. Inspection of
the glass bulb is to be made with the
sprinkler strap in place by looking
through the openings of the sprin-
kler strap.
Any glass bulb that shows evidence
of leakage or that does not have
any fluid must be discarded. Do not
install any bulb type sprinkler if the
bulb is cracked or there is a loss of
liquid from the bulb. With the sprin-
kler held horizontally, a small air bub-
ble 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.
Loss of liquid from a bulb can cause
the sprinkler to fail to activate in a
fire. Install sprinklers in fittings with
the pipe ‘in place’. Sliding piping
through structural members with the
sprinklers in place can severely dam-
age sprinklers.
• Do not apply any thread roughen-
ing process to the sprinkler thread.
Application of this effect can cause
distortion of the frame, which may
result in leakage or damage to the
actuation mechanism.
• When starting the thread of a sprin-
kler, do not over-tighten by hand.
Excessive tightening by hand can
cause damage to the thermal sens-
ing element without knowledge to the
installer.
• Always wrench tighten the sprinklers
with the sprinkler wrench specified
for use with the specific sprinkler
being installed. Using the wrong
wrench can damage the sprinkler.
• Apply sprinkler wrenches to the
proper sprinkler wrench boss/flats
only. Do not allow the sprinkler
wrench to slip during the wrench
tightening procedure. Wrenching
the sprinkler frame arms, deflector,
or thermal sensing element, and/or
wrench slippage, will severely dam-
age the sprinkler.
• Do not over-tighten (maximum torque
is as follows: 1/2” NPT/14 ft.-lbs.; 3/4”
NPT/20 ft.-lbs.; 1” NPT/30 ft.-lbs.).
Over-tightening can distort the sprin-
kler inlet causing leakage or inability
of the sprinkler to operate properly.
• Do not attempt to make-up for insuf-
ficient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Over-tightening can distort
the sprinkler inlet causing leakage or
inability of the sprinkler to operate
properly. Under-tightening can result
in pipe thread leakage. Relocate the
position of the sprinkler, as neces-
sary, to facilitate the adjustment pro-
vided by the escutcheon.
• Do not remove protective devices (for
example, sprinkler straps or protec-
tive caps for concealed type sprin-
klers) until the water supply, either
temporary or permanent, is made
available to the sprinklers for pur-
poses of fire protection. Failure to
maintain the protective devices
where provided may allow damage to
occur to the thermal sensing element
with increasing risk of the sprinkler
failing to activate in a fire or causing
the sprinkler to activate prematurely.
Note
: For upright sprinklers and sprin-
klers installed more than 10 ft. (3,1 m)
above the floor, protective devices (for
example, sprinkler straps or protec-
tive caps for concealed type sprin-
klers) are permitted to be removed
from the sprinklers immediately fol-
lowing their installation. (Where instal-
lation of mechanical services or other
construction work is expected to take
place following the installation of sprin-
klers, consideration should be given to
leaving protective devices in place until
such time as the water supply is made
available to the sprinklers for purposes
of fire protection.)
• After a protective device (for exam-
ple, sprinkler straps or protective
caps for concealed type sprinklers)
is removed, inspect glass bulb sprin-
klers to make sure that the bulbs
contain fluid, and inspect fusible sol-
der type sprinklers for damage to the
fusible element and associated link
assembly parts.
Any sprinkler having a glass bulb
that shows evidence of leakage or
that does not have any fluid must
be replaced, and any sprinkler that
shows evidence of damage to the
fusible element and associated link
assembly parts must be replaced.
• Sprinklers cannot operate properly
with protective devices in place (for
example, sprinkler straps or protec-
tive caps for concealed type sprin-
klers). As applicable, refer to the
“Sprinkler Strap Instructions” pro-
vided in this data sheet.
• Sprinklers that are found to be leak-
ing or exhibiting visible signs of cor-
rosion must be replaced. Leakage
and/or corrosion may cause the
sprinkler to fail to activate in a fire,
and corrosion may cause the sprin-
kler to activate prematurely.
• Automatic sprinklers (including cover
plates of concealed type sprin-
klers) must never be painted, plated,
coated or otherwise altered after
leaving the factory. Painted, coated,
or otherwise altered sprinklers may
interfere with the sprinkler’s ability to
operate in a fire. Modified sprinklers
must be replaced.
• After a fire, bulb type sprinklers that
have been exposed to corrosive
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.
