Cleaning projector optics

This document provides information and procedures for cleaning optical components in the Christie

cinema projectors identified in the products list.

Only these optical components can be cleaned:

• reflector

• integrator

• light engine prism

• projection lens

• UV filter

• IOS Lens 5

The procedures in this document must be performed by service personnel trained by Christie following

consultation with Christie support. Failure to follow this recommendation could result in damage to the

projector and void the warranty.

Typically, optical components do not need to be cleaned frequently if they are installed and operated in

a location that meets or exceeds the environmental standard recommended by Christie. Christie

recommends that all cinema projectors are installed and operated in an environment that meets or

exceeds Underwriters Laboratories (UL) standard 609.50 Pollution Degree 2 and ISO Class 9 Standard

for Office Environments.

Removing and cleaning projector optics

For improving brightness and contrast, the procedures are organized from most to least effective.

Cleaning procedures should be performed in a clean, well lit, and dust-free environment that meets or

exceeds Underwriters Laboratories (UL) standard 609.50 and ISO Class 9 Standard for Office

Environments.

For procedures on removing optical components, see the projector service manual. If the

recommended cleaning supplies described in the procedures are unavailable in your area, contact

Christie service.

Notice. If not avoided, the following could result in property damage.

• Always wear clean, powder-free latex gloves when handling optical components.

• Always handle optics by their edges.

• Handling optics increases the risk of damage. You should clean optics only when necessary.

• Only use solvents if dirt remains after dusting with compressed air.
