Caution: 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. Do not rinse the air filter in water, or use any
detergent or solvent to clean it. Do not directly vacuum the air filter. Doing so could damage the filter.
If dust is difficult to remove or the air filter is damaged, contact Epson to request help with replacing
the air filter.
