Maintenance
Model MBEC-14 Sprinklers should be inspected and the
sprinkler system maintained in accordance with NFPA 25. 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 that 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 un-
til used to minimize the potential for damage to sprinklers that
would cause improper operation or non-operation.
