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.

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. The filter can also be
removed from the side of the projector by removing the radiator and radiator fan pack (on page 59).
1. Remove the top cover (on page 38).
2. Loosen the two screws on the air filter bracket and remove the bracket.
3. Lift the air filter out of the projector.
4. Replace the used air filter with a new one.
The airflow indicator on the new filter must point towards the fan assembly.
