2.2.2 Maintenance of the Cooling System

The high-intensity lamps and electronics rely on a variety of components to reduce internal operating
temperatures. Regular checkup and maintenance of the entire cooling system is critical to prevent overheating
and sudden projector failure and helps make sure reliable operation of all projector components over time.

2.2.3 Ventilation

To make sure adequate airflow around the projector, see the J Series 1000W and 1200W User Manual,
Section 2 Installation and Setup to make sure the installation meets the proper spacing requirements.
• Do not place the projector near a heat source or in an enclosure, unless proper ventilation is provided.
• Do not insert objects into the ventilation openings of the projector.
• Do not spill liquids of any kind into the projector. Should an accidental spill occur, immediately unplug the
projector and have it serviced by a qualified service technician.

Preventative Measures
Wear protective gear approved by Christie,
and handle by the lamp housing 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 gloves (supplied).
NEVER disassemble the integrator module.
NEVER touch or blow on interior
components. Wear gloves (supplied).
NOTE: Normally the internal parts should not
be accessed.
NEVER touch or blow on components. Wear
gloves (supplied).
NEVER touch or blow on the panels.
To avoid the risk of scratching the lens, only
clean the lenses if absolutely necessary. A
small amount of dust on the lenses will have
very little effect on picture quality. The
projection lens should be free of dust and
fingerprints. If the lenses must be cleaned,
use a DRY soft cotton cloth and gently rub in
a circular motion.
How To Clean
Remove any contaminants with pure
isopropyl alcohol and a clean lint-free cloth.
Use ionized pneumatic guns only. Keep
imaging components and yourself
grounded at all times.
Blow off particles with clean, dry de-
ionized air.
Blow off particles with clean, dry de-
ionized air. Then, if necessary, wipe in a
single direction with a clean high quality
optical cloth.
Blow off particles with clean, dry de-
ionized air. If necessary, use a Q-tip with
pure isopropyl alcohol on the glass surface.
NEVER touch the imaging panels. Note
that the green imaging panel has glass
behind it as well.
Blow off particles with clean, dry de-
ionized air.
Use filtered compressed air to blow out dust
and a clean lint-free cloth.
