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.
· Unplug fixture from power.
· 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.
