not clean sprinklers with soap and water, ammonia or any other
cleaning fluids. Remove dust by using a soft brush or gentle vac-
uuming. Remove any sprinkler 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 un-
til used to minimize the potential for damage to sprinklers that
would cause improper operation or non-operation.
