Maintenance
Model F1 Res 44 Sprinklers should be inspected quarterly and the sprinkler system maintained in
accordance with NFPA 25, 13, 13D and 13R. Do not clean sprinklers with soap and water, ammonia or any
other cleaning 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.
