apply pressure with your fingers—use the solution in the cloth to collect the
dirt.
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 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. See also 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.
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 or Lamp 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.
NOTE: For this procedure you will need a compatible Christie Xenon CDXL or CXL
lamp as shown in Section 6, Specifications—never install a lamp intended for a
different projector.
WARNING
Make sure to use the correct wattage lamp supplied by Christie.
