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 using only the W-Type
7 Recessed Sprinkler Wrench (Figure
3). With reference to Figure 1, apply the
W-Type 7 Recessed Sprinkler Wrench
to the sprinkler wrench flats. Torque
sprinklers 7 to 14 ft.-lbs. (9,5 to 19,0
Nm).
Step C.

Care and
Maintenance
The TYCO Series TY-B, 5.6 K-factor,
Upright (TY315) and Pendent (TY325)
Sprinklers must be maintained and ser-
viced in accordance with this section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the outer piece of an
escutcheon, which is used to cover
a clearance hole, can delay sprinkler
operation in a fire situation.
The owner must assure that the
sprinklers are not used for hanging
any objects and that the sprinklers are
only cleaned by means of gently dust-
ing with a feather duster; otherwise,
non-operation in the event of a fire or
inadvertent operation may result.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro-
sion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory.
Modified 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
replaced. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section.)
Thereafter, annual inspections per
NFPA 25 are required; however, instead
of inspecting from the floor level, a
random sampling of close-up visual
inspections should be made.
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 applicable standards
of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the
standards of any other authorities hav-
ing jurisdiction. Contact the installing
contractor or sprinkler manufacturer
regarding any questions.
Automatic sprinklers are recommended
to be inspected, tested, and maintained
by a qualified Inspection Service in
accordance with local requirements
and/or national codes.
