Cleaning the Air Filters

Air filters are attached over the air inlet of the projector to prevent dust. The air filters should be cleaned periodically
in order to maintain projector performance.

WARNING

• Dust in air filters will hinder ventilation of the projector, lead to a rise of the internal temperature and can cause

a fire or malfunction.

• Please do not use a spray containing flammable gas to remove dust attached to the filters, etc. Doing so may

result in fires.

CAUTION

• Before cleaning the filter, first turn off the power, make sure the cooling fan has completely stopped, then turn

off the AC power. Make sure the unit has cooled down completely before cleaning the filter. Removing the filter
cover while the unit is running could result in burns or electric shock from contact with internal parts.

The unit uses a two layer metal-mesh filter installed behind the filter cover. With regular cleaning it can be used
repeatedly.
When cleaning the air filter, clean it all at the same time.
