<br />Care and
<br />Maintenance
<br />
<br />The Series TV-FRS Sprinklers must be
<br />maintained and serviced in accord-
<br />ance with the following instructions:
<br />
<br />NOTES
<br />Before closing a fire protection system
<br />main control valve for maintenance
<br />work on the fire protection system that
<br />it controls, permission to shut down the
<br />affected fire protection system must be
<br />obtained from the proper authorities
<br />and all personnel who may be affected
<br />by this action must be notified.
<br />
<br />Absence of an escutcheon, which is
<br />
<br />used to cover a clearance hole, may
<br />delay the time to sprinkler operation in
<br />a fire situation.
<br />
<br />Sprinklers that are found to be leaking
<br />or exhibiting visible signs of corrosion
<br />must be replaced.
<br />
<br />Automatic sprinklers must never be
<br />painted, plated, coated or otherwise
<br />altered after leaving the factory. Modi-
<br />fied sprinklers must be replaced.
<br />Sprinklers that have been exposed to
<br />corrosive products of combustion, but
<br />have not operated, should be replaced
<br />if they cannot be completely cleaned
<br />by wiping the sprinkler with a cloth or
<br />by brushing it with a soft bristle brush,
<br />
<br />Care must be exercised to avoid dam-
<br />age to the sprinklers - before, during,
<br />
<br />and after installation. Sprinklers dam-
<br />aged by dropping, striking, wrench
<br />twist/slippage, or the like, must be re-
<br />placed. Also, replace any sprinkler that
<br />has a cracked bulb or that has lost
<br />liquid from its bulb. (Ref. Installation
<br />Section).
<br />
<br />Frequent visual inspections are rec-
<br />ommended to be initially performed for
<br />corrosion resistant coated sprinklers,
<br />after the installation has been com-
<br />pleted, to verify the integrity of the cor-
<br />rosion resistant coating. Thereafter,
<br />annual inspections per NFPA 25
<br />should suffice; however, instead of in-
<br />specting from the floor level, a random
<br />sampling of close-up visual inspec-
<br />tions should be made, so as to better
<br />determine the exact sprinkler condi-
