B. Cleaning Enclosure.
The circuit must be turned OFF and allowed to cool to the surrounding ambient temperature before cleaning.
Fixture should be cleaned periodically to maintain maximum light output. Only mild, non-abrasive cleaning
agents should be used. The glass globe should be regularly inspected for scratches and chips, and, if
damaged, must be replaced.
C. Lubrication.
The globe assembly and main housing threads should be well lubricated. If corrosive deposits have
accumulated on the threads and cannot readily be removed with solvents or are severely pitted, the parts
should be discarded and replaced. Re-assemble joint immediately after performing maintenance.
To maintain the integrity of the explosion-proof enclosure never use an abrasive material or file to remove corrosive
deposits from threaded surfaces. In extremely corrosive locations, equipment should be periodically inspected to
guard against unusual deterioration and possible pitting, since this may structurally weaken the enclosure.
D. Service.
Federal Signal will service your equipment and provide technical assistance with any problems that cannot be
handled locally by Federal Signal's Distributor or Manufacturer Representative.
Any units returned to Federal Signal for service, inspection, or repair must be accompanied by a Return
Material Authorization number with a brief explanation of the service being requested and/or the nature of the
malfunction. This R.M.A. can be obtained from a local Federal Signal Distributor or Manufacturer's
Representative.
