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.

NOTICE: 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.
