Care and
Maintenance
The Series TY-FRB, 5.6 K-factor Up-
right and Pendent Intermediate Lev-
el Sprinklers must be maintained
and serviced in accordance with this
section:
Before closing a fire protection sys-
tem main control valve for mainte-
nance work on the fire protection sys-
tem that it controls, permission to shut
down the affected fire protection sys-
tem must be obtained from the prop-
er authorities 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 other-
wise 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. Installa-
tion 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 ad-
dition 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, test-
ed, and maintained by a qualified In-
spection Service in accordance with
local requirements and/or national
code.
