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 globe should be regularly inspected
for scratches and chips, and if damaged, MUST be replaced.
Lubricating the Threaded Joint
The threaded joint on the cover should be kept well lubricated
with a corrosion inhibiting grease such a petrolatum or soap-
thickened mineral oil. If corrosive materials have accumulated
on the threaded joints and cannot be removed with solvents, the
parts should be discarded and replaced.
