Maintenance and cleaning

Maintain the cleanliness of all internal components during any service procedure. All of the projector

optics must remain free of contaminants to perform at the level specified. Even a small amount of dust

or a fingerprint may degrade the image or cause a noticeable reduction of brightness.

Always power down and disconnect/disengage all power sources to the projector before servicing or

cleaning the lens or before any of the projection head covers or doors are loosened and removed. If

the seal is broken while the intake fans are still operating, internal components are immediately

vulnerable to contamination from inbound particles.

Guidelines for cleaning

Use the following guidelines when cleaning components.

Notice. If not avoided, the following may result in equipment or property damage.

• Avoid touching optical elements.

• Always wear clean, lint-free gloves when handling the product.

Component Preventative measures How to clean

020-001790-01 Rev. 1 (03-2020)

Maintaining the cooling system

The high-intensity laser diode 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.

Illumination system,

internal lenses/prisms

Never touch or blow on interior components.

Wear gloves (supplied)

Normally the internal parts should

not be accessed.

Blow off particles with clean, dry

deionized air. If necessary, wipe in a

single direction with a clean high-

quality optical cloth.

Light engine components

Never touch or blow on components.

Wear gloves (supplied).

Blow off particles with clean, dry

deionized air. If necessary, use a Q-

tip with pure isopropyl alcohol on the

glass surface. Never touch the

imaging panels. The green imaging

panel also has glass behind it.

Light engine, DMD panels

Never touch or blow on the panels. Blow off particles with clean, dry

deionized air.

Fan

Check for dust build-up on blades. Inspect

harness connection for proper seating. Never

touch or blow on the fan blade.

Blow off particles with clean, dry

deionized air.

Projection lens

To avoid the risk of scratching the lens, only

clean the lenses if absolutely necessary. A

small amount of dust on the lenses has little

effect on picture quality. The projection lenses

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.

Use filtered compressed air to blow

out dust and a clean lint-free cloth.

Intake

Christie recommends operating the projector

in environments with an AQI (air quality index)

of 50 or lower. If the projector is operated in

environments with an AQI higher than 50,

additional preventative maintenance may be

required. This additional preventative

maintenance requires returning the projector

to a Christie Service Center to be

disassembled and cleaned. The time between

preventative maintenance cycles varies based

on environmental conditions.

Christie recommends inspecting the

projector for contamination at least

every six months. If a build-up of

dust on the intake exists, use

filtered, compressed air to blow out

the dust and a clean, lint-free cloth

to wipe surfaces and ducts.
