Cleaning
ELECTRICAL SHOCK HAZARD! Disconnect from AC when servicing.
Always wear gloves when handling internal components.
Maintaining the cleanliness of all internal components during any service procedure is critical. In particular, all
of the projector’s optics must remain free of contaminants in order to perform at the level specified for the
projector. Even a small amount of dust or a fingerprint may degrade the image or cause a noticeable reduction
of brightness. During servicing, take all necessary measures to avoid touching or contaminating optical
surfaces. A
MINIMUM
amount of cleaning—hopefully none—should be required during and after servicing. If
during servicing you notice that a component is dirty or dusty, or if you have accidentally contaminated a
component, refer to
to determine the appropriate cleaning action needed.
NOTE:
It is critical the
projector be powered OFF and disconnected from AC before the lens or any of the projection head covers/
doors are loosened and removed.

Components
Preventative Measures
Cleaning Technique
Lamp
Wear protective gear approved by Christie,
and handle by the ends only. Never grip the
glass portion of the lamp.
NOTE:
Any fin-
gerprints will reduce output quality and
shorten lamp life.
Remove fingerprints or dirt with pure isopropyl
alcohol and a clean lint-free cloth.
Lamp Reflector
Wear protective gear approved by Christie.
Remove fingerprints or dirt with methanol and
clean, microfiber cloth such as Melles Griot
18LAB024 or equivalent.
Illumination Optics System,
general
NEVER
touch or blow on exposed compo-
nents. Wear gloves (supplied).
Use ionized pneumatic guns only. Keep imaging
components and yourself grounded at all times.
Integrator
NEVER
disassemble the integrator module.
Blow off visible particles with clean, dry de-
ionized air.
Illumination System, internal
lenses/prisms
NEVER
touch or blow on interior compo-
nents. Wear gloves (supplied). NOTE: Nor-
mally the internal parts should not be
accessed.
Blow off particles with clean, dry de-ionized air.
Then, if necessary, wipe in a single direction
with a clean high quality optical cloth.
Light Engine components
NEVER
touch or blow on components. Use
gloves.
Blow off particles with clean, dry de-ionized air.
If necessary, use a split Q-tip with pure isopro-
pyl alcohol on the glass surface. NEVER touch
the imaging panels. Note that the green imaging
panel has a glass behind it as well.
Light Engine, DMD panels
NEVER
touch or blow on the panels.
Blow off particles with clean, dry de-ionized air.
Projection Lens
To avoid the risk of scratching the lens, only
clean the lenses if absolutely required. A
small amount of dust on the lenses will have
very little effect on picture quality. The pro-
jection lens should be free of dust and fin-
gerprints. If the lenses must be cleaned, use
a DRY soft cotton cloth. Rub gently in a cir-
cular motion.
Use filtered compressed air to blow out dust.
Remove fingerprints or dirt with Melles Griot
Cleaning Fluid 18LAB011(or equivalent) and a
clean lint-free cloth.
