Maintenance
Model F1 Res 30 LL, 49 LL, F1 Res 58 LL and F1 Res 44
LL Sprinklers should be inspected and the sprinkler sys-
tem maintained in accordance with NFPA 25, 13, 13D, and
13R. Do not clean sprinkler with soap and water, Ammonia
or any other cleaning fluids. Remove dust by using a soft
brush or gentle vacuuming. Replace any sprinkler which
has been painted (other than factory applied) or damaged
in any way. A stock of spare sprinklers should be main-
tained to allow quick replacement of damaged or operated
sprinklers. Prior to installation, sprinklers should remain
in the original cartons and packaging until used. This will
minimize the potential for damage to sprinklers that could
cause improper operation or non-operation.
