Section 4: Maintenance

Removing Fingerprints, Smudges, Oil

1. First brush dust off with a camel-hair brush and/or blow dust away with compressed air.

2. Fold a clean microfibre cloth and dampen with methanol. Wipe evenly with the smooth portion of

the cloth that has no folds or creases. Do not apply pressure with your fingers-use the solution in

the cloth to collect the dirt.

OTHER COMPONENTS

In normal operating environments check, clean and treat the following components approximately

every 6 months to ensure proper lamp and projector function.

Clean Lamp Fan: A clogged lamp fan impeller or motor can reduce air flow, leading to possible

overheating and failure of the lamp.

1. Vacuum loose dirt from the lamp fan impeller.

2. If necessary, use a brush with hot water and suitable detergent.

IMPORTANT! Do not bend the impeller blades or loosen the balancing weights.

Igniter: Clean the high voltage terminal and insulator to remove accumulated dust or dirt.

Air Flow Interlocks: The lamp fan vane switch is located within the lamp cooling compartment. The

extractor vane switch is located just inside the top duct on the projector lid. Check and, if necessary,

clean the switches to remove accumulated dust or dirt that could impede movement. Within the

exhaust duct connected at the top of the projector, adequate airflow must be maintained and routed to

outside of the building. Inspect regularly and confirm there are no obstructions or "kinks" within the

ducting, all air intake areas of the CP2000 are unobstructed and exhaust airflow is within the range

shown in Table 2.1. Ensure lamp wiring does not interfere with the vane switch. Refer to 4.2

Maintaining Proper Cooling.

Laminar Airflow Device (LAD): Whenever checking/replacing the air filter on the side of the

projector, also visually check the small square laminar airflow device (LAD) just beyond the filter

opening. The LAD should be nearly white in color. If very dark (rare), it may have to be replaced by a

qualified service technician. Contact Christie or your dealer.

4.4 REPLACING LAMP AND FILTER

The high brightness of your projector is provided by a Xenon lamp mounted at two ends within a

reflector and housed in the locked lamp compartment of the projection head. When the lamp

approaches the end of its life, it must be replaced-do not exceed warranted lamp life by more than

20%, as an old lamp becomes increasingly and dangerously fragile, resulting in possible explosion.

To determine the age of your current lamp, consult the Status menu in the Touch Panel Controller.

Lamp hours appear under Environment: Lamp. Lamp hours are also displayed in the password-

protected Advanced Lamp menu and the Advanced Lamp History menu.

It is recommended that you replace the air filter with every lamp replacement, or sooner in dusty or

dirty environments. Check its condition monthly in all projectors.
