Installation and Maintenance Manual

Cleaning the Fixture

The fixture should be cleaned periodically to maintain maximum
light output. Use only mild, non-abrasive cleaning agents. The
glass dome should be regularly inspected for scratches and chips,
and if damaged, must be replaced.
NOTE: Maintenance procedures sometime require fixtures to be
hosed down for good housekeeping. The circuit must be turned
OFF and the dome MUST be allowed to cool to ambient room
temperature before cleaning.

Lubricating the Threaded Joints

EXPLOSION HAZARD—Never use an abrasive material or file to
remove corrosive products 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.
The threaded joints on the pendant mount should be well lubricated.
If corrosive products have accumulated on the explosion-proof joints
and cannot readily be removed with solvents, the parts should be
discarded and replaced.

Ordering Accessories and Replacement Parts

EXPLOSION HAZARD–Damaged domes can lead to explo-
sions that could result in serious injury or death. If the dome is
damaged, it MUST be replaced.
Typical spare parts are listed in Table 2. Due to certification,
certain component parts are not available for field replacement.
Units with this type of damage must be either replaced entirely or
returned to Federal Signal for service.
