6.3.3 Other Components

In a normal operating environment check, clean and treat the following components every 6 months or so to
help ensure proper lamp and projector function:

Lamp Fan

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.
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 that 1) there are no obstructions or kinks within the ducting, 2) all air intake areas of the CP2000-SB
are unobstructed, and 3) exhaust airflow is within the range shown in Table 2.1 on page 11. Ensure lamp
wiring does not interfere with vane switch. Refer to

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.
6.4 Replacing the Lamp & 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.
