Maintenance
To maintain optimum performance and minimize wear, the user should clean this product
frequently. Usage and environment are contributing factors in determining the cleaning
frequency.
As a rule, the user should clean this product at least twice a month. Dust build up reduces
light output performance and can cause overheating. This can lead to reduced light
source life and increased mechanical wear.
To clean a product, follow the recommendations below:
Unplug the unit from power.
Wait until the unit has cooled.
Use a vacuum (or dry compressed air) and a soft brush to remove dust collected on
the external vents and accessible internal components.
Clean all external optics and plastic surfaces with a mild solution of non-ammonia
glass cleaner or isopropyl alcohol.
Apply the solution directly to a soft, lint-free cotton cloth or a lens cleaning tissue.
Wipe any dirt or grime to the outside edge of the lens surface.
Gently polish the lens surfaces until they are free of haze and lint.
Always dry the external optics and plastic surfaces carefully after cleaning them.
Refrain from spinning this product’s fan using compressed air.
