sprinkler. Readjust the position of the
sprinkler fitting to suit.
The Series TY-B Pendent and Up-
right Sprinklers must be installed in
accordance with the following instruc-
tions.
Step 1. Pendent sprinklers are to be
installed in the pendent position, and
upright sprinklers are to be installed in
the upright position.
Step 2. With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
6 Sprinkler Wrench (Ref. Figure 7),
except that an 8 or 10 inch adjustable
Crescent wrench is to be used for wax
coated sprinklers. With reference to
Figures 1, 2, 3, and 4 the W-Type 7
Sprinkler Wrench or the adjustable
Crescent wrench, as applicable is to
be applied to the wrench flats.
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 wrench flats or frame
arms and, consequently, exposure of
bare metal to the corrosive environ-
ment. The jaws of the wrench should
be opened sufficiently wide to pass
over the wrench flats without damag-
ing the wax coating. Before wrench
tightening the sprinkler, the jaws of the
wrench are to be adjusted to just con-
tact the sprinkler wrench flats. After
wrench tightening the sprinkler, loosen
the wrench jaws before removing the
wrench.
After installation, the sprinkler wrench
flats and frame arms must be in-
spected and the wax coating re-
touched (repaired) whenever the coat-
ing has been damaged and bare metal
is exposed. The wax coating on the
wrench flats can be retouched by gen-
tly 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 ap-
plied to the wrench flats and frame
arms is permitted, and the retouching
is to be performed only at the time of
the initial sprinkler 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.
The Series TY-B Recessed Pendent
Sprinklers must be installed in ac-
cordance with the following instruc-
tions.
Step A. After installing the Style 10 or
40 Mounting Plate, as applicable, 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 using only the W-Type
7 Recessed Sprinkler Wrench (Ref.
Figure 8). With reference to Figure 3
or 4, the W-Type 7 Recessed Sprinkler
Wrench is to be applied to the sprinkler
wrench flats.
Step C. After the ceiling has been in-
stalled or the finish coat has been ap-
plied, slide on the Style 10 or 40 Clo-
sure over the Series TY-B Sprinkler
and push the Closure over the Mount-
ing Plate until its flange comes in con-
tact with the ceiling.
Care and
Maintenance
The Series TY-B Sprinklers must be
maintained and serviced in accord-
ance with the following instructions:
NOTES
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 system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
The owner must assure that the sprin-
klers are not used for hanging of any
objects; otherwise, non-operation in
the event of a fire or inadvertent opera-
tion may result.
Absence of an escutcheon, which is
used to cover a clearance hole, may
delay the time to sprinkler operation in
a fire situation.
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).
Frequent visual inspections are rec-
ommended to be initially performed for
corrosion resistant coated sprinklers,
after the installation has been com-
pleted, to verify the integrity of the cor-
rosion resistant coating. Thereafter,
annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating, as it may
be affected by the corrosive conditions
present.
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.
Automatic sprinkler systems should be
inspected, tested, and maintained by
a qualified Inspection Service in ac-
cordance with local requirements
and/or national codes.
