Cleaning the Air Filter and Vents
Replacing the Air Filter
Parent topic: Maintaining and Transporting the Projector
Cleaning the Air Filter and Vents
Clean the projector's air filter or vents if they get dusty, or if you see a message telling you to clean them.
Clean the air filter immediately when the projector displays a message indicating high temperatures
inside the projector. It is recommended that you clean the filter every 5000 hours. Clean the filter and
vents more frequently if you are using the projector in a dusty or smoky environment.
Caution: If you do not perform regular maintenance, the projector will display a high temperature
warning. Do not wait until this message appears to clean your air filter and vents, as prolonged exposure
to high temperatures can reduce the life of your projector.
1. Turn off the projector and unplug the power cord.
2. Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as
a paintbrush).
Note: You can remove the air filter so you can clean both sides of it. Do not rinse the air filter in
water or use any detergent or solvent to clean it.
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.
3. If dust is difficult to remove or the air filter is damaged, replace the air filter.
