Filtration

Filters help to prevent dust, smoke, fog, and other foreign materials from entering the projector.
In environments where dust, smog, dirt, and other contaminants are higher than normal, Christie
strongly recommends replacing the air filter more frequently than your maintenance schedule
indicates.
Notice. If not avoided, the following could result in property damage.
• Do not operate the product without the filter installed.
• Do not operate the product with an incorrectly installed filter.
• Do not reuse an old air filter.

Replacing the light engine compartment air filter

This air filter is located on the air intake side of the projector, behind the radiator.
These instructions detail accessing the air filter from the top of the projector.
1. Slide the small door on the top of the unit towards the middle and open the door.

Preventative measures
Never touch or blow on the panels.
Normally the internal
parts should not be
accessed.
To avoid the risk of scratching the
lens, only clean the lenses if
absolutely necessary. A small
amount of dust on the lenses has
little effect on picture quality. The
projection lens should be free of
dust and fingerprints. If the lenses
must be cleaned, use a dry, soft
cotton cloth and gently rub in a
circular motion.
Maintenance and cleaning
How to clean
glass surface. Never touch the
imaging panels.
Blow off particles with clean, dry de-
ionized air.
Use filtered compressed air to blow
out dust and a clean lint-free cloth.
