Air Filter and Vent Maintenance

Regular filter maintenance is important to maintaining your projector. Clean
the air filter when a message appears telling you the temperature inside the
projector has reached a high level. It is recommended that you clean these parts
over a 10,000‑hour period. Clean them more often than this if you use the
projector in a particularly dusty environment.
Attention
If regular maintenance is not performed, your Epson projector will notify you when
the temperature inside the projector has reached a high level. Do not wait until this
warning appears to maintain your projector filter as prolonged exposure to high
temperatures may reduce the life of your projector or lamp.

telling you to clean them.

Gently remove the dust using a small vacuum designed for computers or a
very soft brush (such as a paintbrush).
You can remove the air filter so that you can clean both sides. Do
not rinse the air filter in water, or use any detergent or solvent to
clean it.
Attention
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.

If dust is difficult to remove or the air filter is damaged, replace the air
filter.
