Do not use a lens cleaner that contains flammable gas. The high heat generated by the
projector lamp may cause a fire.

Do not use glass cleaner or any harsh materials to clean the lens and do not subject the lens
to any impacts; you may damage it. Do not use canned air, or the gases may leave a residue. Avoid
touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.

Air Filter and Vent Maintenance
Regular filter maintenance is important to maintaining your projector. Your Epson projector is designed
with an easily accessible, user-replaceable filter to protect your projector and make regular maintenance
simple. Filter maintenance intervals will depend on the environment.
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.
