You need to clean the projector's air filters in the following situations:
The filter or vents get dusty.
You see a message telling you to clean it.
The projector's Filter indicator flashes orange.
Turn off the projector and unplug the power cord.
Carefully remove the dust using a vacuum cleaner or a brush.
Turn the projector upside down.
When placing the projector upside down, be sure to place a cloth or other cushioning material underneath the projector to protect the lens. (EB-L790SE/EB-L795SE/EB-L690SE/EB-L695SE/EB-L790SU/EB-L690SU/EB-L695SU)
Loosen the screws and open the air filter cover.
Pull the air filter out of the projector.
Tap each side of the air filter 4 to 5 times to shake off any excess dust.
Do not use excessive force when tapping the air filter, or it may crack and become unusable.
Vacuum the front of the air filter (the side with the tabs) to remove any remaining dust.
Do not rinse the air filter in water, or use any detergent or solvent to clean it.
Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector's optics or other sensitive areas.
Place the air filter in the projector as shown.
Close the air filter cover and tighten the screws.
