Maintenance
Model F1 Res 30 LL, 49 LL, F1 Res 58 LL and F1 Res 44
LL Sprinklers should be inspected quarterly, and the sprin-
kler system 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 us-
ing a soft brush or gentle vacuuming. Remove any sprin-
kler 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
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.
