4.2.2 Other Components

In a normal operating environment check, clean and treat the components listed below every 6 months or so to

help ensure proper lamp and projector function.

A clogged lamp fan impeller or motor can reduce air flow leading to possible overheating and failure of the

lamp. Clean/treat the impeller as follows:

1. Vacuum loose dirt from the lamp fan impeller.

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

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

C or elevation (above sea level) greater than 3000 feet.

The CP2000-ZX uses two airflow interlocks; lamp fan vane switch and extractor vane switch.

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 outside of the building. Inspect regularly and

confirm that 1) there are no obstructions or "kinks" within the ducting, 2) all air intake areas are unobstructed,

and 3) exhaust airflow is at least 450 CFM* (measured at the end of the duct when not connected to the

projector). Refer to

Whenever checking/replacing the air filter on the side of the projector, also visually check the small square

laminar airflow device (LAD) filter just beyond the filter opening. The LAD filter should be nearly white in

color. If it appears a dark gray color (rare) it will require replacement by a qualified technician only. Contact

Christie or your dealer.
