Care and
Maintenance
The Series RFII-MRI Concealed
Pendent Sprinklers must be maintained
and serviced 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, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the Cover Plate/Retainer
Assembly can delay sprinkler opera-
tion in a fire situation.
When properly installed, there is a
nominal 3/32 in. (2,4 mm) air gap
between the lip of the Cover Plate and
the ceiling, as shown in Figure 2.
This air gap is necessary for proper
operation of the sprinkler. If the ceiling
requires repainting after sprinkler
installation, ensure that the new paint
does not seal off any of the air gap.
Do not pull the Cover Plate relative to
the Enclosure. Separation may result.
Sprinklers which 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.
Exercise care to avoid damage to sprin-
klers before, during, and after instal-
lation. Replace sprinklers damaged
by dropping, striking, wrench twist-
ing, wrench slipping, or the like. Also,
replace any sprinkler that has a cracked
bulb or that has lost liquid from its bulb.
(See the Installation section.)
If you must remove a sprinkler, do not
reinstall it or a replacement without
reinstalling the Cover Plate/Retainer
Assembly. If a Cover Plate/Retainer
Assembly becomes dislodged during
service, replace it immediately.
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 (NFPA) - for example,
NFPA 25 - in addition to the standards
of any other authorities having jurisdic-
tion. Contact the installing contractor
or sprinkler manufacturer regarding 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 code.
