2. Keep the vents on the sides, top and bottom of the projector clear. Make sure to keep papers, books and other

tabletop paraphernalia away from the projector. Even partially blocking one vent disrupts the airflow enough to

shorten the life of the lamp and other internal parts.

3. Use your projector in as clean environment as possible. Polluted air can cause dust to build up on filters or vents,

causing the temperature to go up. This is especially true of ceiling mounted projectors. Check and clean your

projector at least every 250 hours of operation. Filter and screen cleaning instructions are available from the ASK

Proxima website.
