Maintaining the cooling system

The high-intensity lamps and electronics rely on a properly functioning cooling system. Regular
maintenance of the cooling system is critical to prevent overheating and sudden projector failure and
helps ensure reliable operation.
Caution! If not avoided, the following could result in minor or moderate injury.
• Do not remove or disable the vane switch.
• Do not attempt to operate the product with inadequate airflow which can result in dangerous
overheating.
• Keep fingers and other body parts away from the moving parts in the product. Tie back long
hair, and remove jewelry and loose clothing before manually adjusting the product.
Notice. If not avoided, the following could result in property damage.
• Use only high efficiency Christie approved filters.
• Do not reuse an old air filter.
• Do not operate the product without the filter installed.

Ventilation

Vents and louvers in the projector covers provide ventilation, both for intake and exhaust.
Never block or cover these openings. Do not install the projector near a radiator or heat register, or
within an enclosure. To ensure adequate airflow around the projector, with a minimum clearance of
25cm (10") on the left, right and rear sides of the projector from any walls or other obstructions.

Replacing the dust air filter

Complete this procedure to replace the dust air filter.
Check projector air dust filters, at minimum, every month.
Dust air filters must be replaced whenever the lamp is replaced or between 200-500 hours, depending
on use. A clogged air filter reduces air flow and can lead to overheating and failure of the projector.
Check monthly by inspecting its color through the side vent grille with a flashlight. Replace grey
colored filters.
Leave the filters in their sealed packaging until ready for use.
1. Unscrew the two captive screws at the top of each filter door. Allow the door to rest down and
away from the projector.
2. Slide the air filter out and replace, vacuum or wash the filter.
Wash using mild soap and water. Dry the filter before using.
3. Insert the new or clean air filter.
