Igniter; Air Flow Interlocks; Laminar Airflow Device (Lad); Lamp Replacement - Christie CP2000-SB Setup Manual

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 3.1. 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.
