Care and
Maintenance
The TYCO Model RFII HSW Concealed
Sprinkler must be maintained and ser-
viced in accordance with this section.
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 is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION, such as NFPA 25, in
addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or product
manufacture with any questions.
Automatic sprinkler systems should be
inspected, tested, and maintained by a
qualified Inspection Service in accor-
dance with local requirements and/or
national codes.
When properly installed, there is a
nominal 5/32 in. (4,0 mm) air gap
between the lip of the Cover Plate and
the wall, as shown in Figure 3. This
air gap is necessary for proper oper-
ation of the sprinkler. If the wall is to
be repainted after the installation of
the sprinkler, care must be exercised
to ensure that the new paint does not
seal off any of the air gap.
Factory painted cover plates must not
be repainted. They should be replaced
if necessary, by factory painted units.
Non-factory applied paints may
adversely delay or prevent sprinkler
operation in the event of a fire.
If removal of the Cover Plate is neces-
sary relative to the Enclosure, be con-
scious not to be too forceful, where
separation may result.
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 or over heated sprinklers must be
replaced.
Care must be exercised to avoid
damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced.
If a sprinkler must be removed, do not
reinstall it or a replacement without
reinstalling the Cover Plate Assembly.
If a Cover Plate Assembly becomes
dislodged during service, replace it
immediately.
