Lamp Replacement - Christie CP2000-XB Setup Manual

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 away from the operating
area surrounding the projector (or any nearby projectors). Inspect regularly and confirm that 1) there are no
obstructions or kinks within the ducting, 2) all air intake areas of the projection head and ballast are
unobstructed, and 3) exhaust airflow at the top vent is 600 CFM. Make sure lamp wiring does not interfere with
vane switch operation. 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.
