Installation and Maintenance Instructions

Maintaining the Model 371LEDX-120

EXPLOSION HAZARD — To prevent the ignition of hazardous
atmospheres, disconnect the beacon from the supply circuit
before opening it.
EXPLOSION HAZARD — Do not disconnect the beacon while
the circuit is live or unless the area is known to be free of
ignitable concentrations. Keep the beacon tightly closed when in
operation.
EXPLOSION HAZARD — To maintain the vapor-tight enclosure,
do not damage the dome or threads while disassembling the
beacon. Lubricated threaded joints that are exposed for long
periods of time may attract small particles of dirt or other foreign
materials. Housing and cover joints should be reassembled
immediately with all the threads fully engaged.
Establishing a regular maintenance schedule for the Model
371LEDX-120 extends the life of the light and ensures safety.
Periodically check that the light operates properly. Also, inspect
the dome for cracks, crazing (hairline cracks), discoloration, and
other defects.
The threaded dome ring joint should be well lubricated with
petroleum or a soap-thickened mineral oil. If corrosive products
have accumulated on joints and cannot readily be removed with
solvents, the parts should be discarded and replaced.

Cleaning the Dome

NOTE: Maintenance procedures sometimes require fixtures to be
hosed down for good housekeeping. The electrical circuit should
be turned off prior to hosing down the light.
Clean the dome periodically to maintain maximum light output.
Use only mild, non-abrasive cleaning agents.
