2.0.2 Inspect Ventilation

Vents and louvers in the projector covers provide ventilation, both for intake and exhaust. Inspect the projector
regularly to ensure these openings are not blocked or covered. Verify the projector is not installed near a
radiator, heat register, or within an enclosure. To ensure adequate airflow around the projector, keep a
minimum clearance on the left, right, and rear sides of the projector.

PREVENTATIVE MEASURES
Wear protective clothing approved by Christie,
and handle by the ends only. Never grip the glass
portion of the lamp. NOTE: Any fingerprints
will reduce output quality and shorten lamp life.
Never touch or blow on exposed components.
Wear nitrile gloves.
Never disassemble the integrator module.
Never touch or blow on interior components.
Wear nitrile gloves. NOTE: Normally the
internal parts should not be accessed.
Never touch or blow on components. Use nitrile
gloves.
Never touch or blow on the panels.
To avoid the risk of scratching the lens, only
clean the lenses if absolutely required. A small
amount of dust on the lenses does not effect
picture quality.
HOW TO CLEAN
Remove fingerprints or dirt with pure
isopropyl alcohol and a clean lint-free cloth.
Use ionized pneumatic guns only. Wear a
ground strap and observe anti-static protocols
when servicing projector components.
Remove visible particles with clean, dry
deionized air.
Remove particles with clean, dry deionized
air. Then, if necessary, wipe in a single
direction with a clean high quality optical
cloth.
Remove particles with clean, dry deionized
air. If necessary, use a Q-tip with pure
isopropyl alcohol on the glass surface. Never
the imaging panels. The green imaging panel
has a glass behind it.
Remove particles with clean, dry deionized
air.
Use filtered compressed air to remove dust
and a clean lint-free cloth.
Use a DRY soft cotton cloth. Rub gently in a
circular motion.
