Cleaning the Fixture
EXPLOSION HAZARD: 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.
Maintenance procedures sometimes require fixtures to be hosed
down for good housekeeping. The circuit should be turned off
prior to hosing down the fixture.
The fixture 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.
