To maintain the explosion-proof integrity of the enclosure, DO NOT damage
the globe or threads while disassembling or reassembling unit.
Lubricated joints exposed for long periods of time may attract small particles
of dirt or other foreign materials.
Body and cover joints should be reassembled as quickly as possible.
A.
Cleaning Enclosure.
Maintenance procedures sometimes require fixtures to be hosed down for
good housekeeping. The circuit should be turned off prior to hosing down.
The 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.
B.
Lubrication.
Threaded joint on cover should be kept well lubricated with a corrosion in-
hibiting grease such a petrolatum or soap-thickened mineral oil. If corrosive materials
have accumulated on the explosion-proof joints and cannot be removed with solvents,
the parts should be discarded and replaced.
Never use an abrasive material or file to remove corrosive materials from
threaded surfaces. In extremely corrosive locations, equipment should be
periodically inspected to guard against unusual deterioration and possible
porosity, since this may weaken the enclosure structurally.
C.
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.
