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.
