Maintenance
Model RFC43 and RFC49 Concealed Sprinklers should
be inspected quarterly and the sprinkler system main-
tained in accordance with NFPA 25. Do not clean sprin-
klers with soap and water, ammonia or any other clean-
ing fluids. Remove dust by using a soft brush or gentle
vacuuming. Remove any sprinkler cover plate assembly
which has been painted (other than factory applied) or
damaged in any way. A stock of spare sprinklers should
be maintained to allow quick replacement of damaged or
operated sprinklers. Prior to installation, sprinklers should
be maintained in the original cartons and packaging until
used to minimize the potential for damage to sprinklers
that would cause improper operation or non-operation.
