Maintenance
Model DH56 Quick Response Dry Sprinklers should be in-
spected and the sprinkler system maintained in accordance
with NFPA 25. Do not remove the factory applied thermally
sensitive wax fillet between the bulb supporting cup and the
wrenching boss. Do not replace this wax with a substitute
substance. An alternate substance may interfere with proper
operation of the sprinkler. 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 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 their original cartons and packaging until used
to minimize the potential for damage to sprinklers that would
cause improper operation or non-operation.
