heated rod, in order to prevent the
installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuc-
cessful, additional wax can be ordered
in the form of a wax stick (the end of
which is color coded). Only the correct
color coded wax is to be used, and
retouching of wrench flats and frame
arms is only permitted at the time of
initial sprinkler installation. With the
steel rod heated as previously de-
scribed, touch the rod to the area re-
quiring additional wax with the rod an-
gled downward, and then touch the
wax stick to the rod approximately
one-half inch away from the area re-
quiring retouching. The wax will melt
and run down onto the sprinkler.
The
Series TY-B Recessed Horizon-
tal Sidewall Sprinklers
must be in-
stalled in accordance with the follow-
ing instructions.
Step A.
Recessed horizontal sidewall
sprinklers are to be installed in the
horizontal position with their centerline
of waterway perpendicular to the back
wall and parallel to the ceiling. The
word “TOP” on the Deflector is to face
towards the ceiling.
Step B.
After installing the Style 10
Mounting Plate over the sprinkler
threads, hand tighten the sprinkler into
the sprinkler fitting.
Step C.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
7 Recessed Sprinkler Wrench (Ref.
Figure 5). With reference to Figure 1,
the W-Type 7 Recessed Sprinkler
Wrench is to be applied to the sprinkler
wrench flats.
Step D.
After the ceiling has been in-
stalled or the finish coat has been ap-
plied, slide on the Style 10 Closure
over the Series TY-B Sprinkler and
push the Closure over the Mounting
Plate until its flange comes in contact
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.
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
shipped or stored where their tempera-
ture will exceed 100°F/38°C and they
must never be painted, plated, coated
or otherwise altered after leaving the
factory. Modified sprinklers must be re-
placed. Sprinklers that have been ex-
posed to corrosive products of com-
bustion, but have not operated, should
be replaced if they cannot be com-
pletely 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
