word “TOP” on the Deflector is to face
towards the ceiling.
Step B. After installing the Style 10 or
20 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 11). With reference to Figure 2
or 3, the W-Type 7 Recessed Sprinkler
Wrench is to be applied to the sprinkler
wrench flats.
Step D. After the wall has been in-
stalled or the finish coat has been ap-
plied, slide on the Style 10 or 20 Clo-
sure over the Series TY300-FRB
Sprinkler and push the Closure over
the Mounting Plate until its flange
comes in contact with the wall.
Care and
Maintenance
The Series TY300-FRB Sprinklers
must be maintained and serviced in
accordance with the following instruc-
tions:
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
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.
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.
