Cleaning Projector Optics; Tools Required For Cleaning Optics; Cleaning Methods - Christie CP2420-Xe Service Manual

Cleaning projector optics

Learn how to clean and maintain optical components in the projector.
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.
Cleaning procedures 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.
Only the following optical components can be cleaned:
• light engine prism
• UV filter
• projection lens
• reflector
• integrator
