IF FINGERPRINTS, SMUDGES, OIL:
1. First brush dust off with a camel-hair brush and/or blow dust away with
compressed air.
2. Fold a clean microfibre cloth and dampen with methanol. Make sure to wipe
evenly with the smooth portion of the cloth that has no folds or creases. Do not
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 —
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 are unobstructed, and 3)
exhaust airflow is within the range shown in Table 2.1. Make sure lamp wiring does
not interfere with vane switch. See also 6.2, Maintaining Proper Cooling.
LAMINAR AIRFLOW DEVICE (LAD) —
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 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.
