General Maintenance
To maintain optimum performance and minimize wear, fixtures
should be cleaned frequently. Usage and environment are
contributing factors in determining frequency. As a general rule,
fixtures should be cleaned at least twice a month. Dust build up
reduces light output performance and can cause overheating.
This can lead to reduced lamp life and increased mechanical
wear. Be sure to power off fixture before conducting
maintenance.
● Use a vacuum or air compressor and a soft brush to remove
dust collected on external vents.
● Clean all glass when the fixture is cold with a mild solution of
glass cleaner or Isopropyl Alcohol and a soft lint free cotton
cloth or lens tissue.
● Apply solution to the cloth or tissue and drag dirt and grime to
the outside of the lens.
● Gently polish optical surfaces until they are free of haze
and lint.
The cleaning of external optical lenses and/or mirrors must be
carried out periodically to optimize light output. Cleaning
frequency depends on the environment in which the fixture
operates. Damp, smoky or particularly dirty surroundings can
cause greater accumulation of dirt on the unit’s optics. Clean
with soft cloth using normal glass cleaning fluid. Clean the
external optics at least every 20 days. Clean the fixture at least
every 30/60 days.
Always dry the parts carefully after cleaning them.
Never spin a fan using compressed air.
