WARNING SHOCK
when power is applied. To reduce shock hazards during maintenance, polarity must be
observed when connecting AC units to the power source.

WARNING EXPLOSION HAZARD
is live or unless the area is known to be free of ignitable concentrations. To prevent
ignition of hazardous atmospheres, disconnect the fixture from the supply circuit before
opening.
Note: Maintenance procedures sometimes 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. Periodic cleaning is important to prevent
the accumulation of dust and dirt, which could impair the light output of the fixture.
Changing The Lamp:
1. Remove the glass dome assembly from the main casting by rotating the dome
counterclockwise.
2. Loosen the lens clip screw (1 to 3 turns) and rotate 90 degrees. Remove the lens
to expose the lamp. Remove the lamp, push it in and turn it counterclockwise 3
degrees and remove from the socket.
3. Replace the lamp.
4. Place the lens in position under the hold-down tabs and rotate the clip into place on
the lip of the lens and tighten the screw.
5. Reassemble the unit by trading the glass dome assembly into the main housing until
tight.
Cleaning The Enclosure:
Fixtures should be cleaned periodically to maintain maximum light output. Only mild,
non-abrasive cleaning agents should be used. The glass dome should be regularly
inspected for scratches and chips, and if damaged, must be replaced.
