Design Criteria
The 11.2 K-Factor, Model LD (TY5153)
Upright Large Drop Sprinklers are only
for use with National Fire Protection
Association “large drop sprinkler” in-
stallation criteria.
Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb allowing the sprinkler to ac-
tivate and flow water.

IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Installation
NOTE
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 horizontal, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm) for the 155°F/68°C to 3/32
inch (2,4 mm) for the 286°F/141°C rat-
ing.
The Model LD Sprinklers must be in-
stalled in accordance with the follow-
ing instructions:
Step 1. With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the Model LD Sprinkler into the sprin-
kler fitting.
Step 2. UsingtheW-Type3(EndB)
Sprinkler Wrench (Ref. Fig. 2) applied
to the sprinkler Wrench Flats (Ref. Fig.
1), tighten the Model LD Sprinkler into
the sprinkler fitting.
NOTE
A leak tight 3/4 inch NPT sprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Care and
Maintenance
The Model LD Sprinklers must be
maintained and serviced in accord-
ance with the following instructions:
NOTE
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection systems must
be obtained from the proper authori-
ties and all personnel who may be
affected by this action must be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory. Modi-
fied sprinklers must be replaced.
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.
Care must be exercised to avoid dam-
age to the sprinklers - before, during,
and after installation. Sprinklers dam-
aged 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 in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative to
any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
