Air Filter and Vent Maintenance
143
Regular filter maintenance is important to maintaining your projector. Clean
the air filer 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 2000-hour period. Clean them with shorter periodicity 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.
