Cleaning the Reflector

IF DUSTY:

 Brush most of the dust off with a camel-hair brush and/or blow dust away with

compressed air.

 If some dust remains, just leave as is—air circulating at the lamp is unfiltered, so

some dust is inevitable. Avoid unnecessary cleaning.

IF FINGERPRINTS, SMUDGES, OIL:

 First brush dust off with a camel-hair brush and/or blow dust away with

compressed air.

 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:

 Vacuum loose dirt from the lamp fan impeller.

 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 6.2, 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.
