6 Cleaning Projector Optics
This section provides information and procedures for cleaning optical components. Only these optical
components can be cleaned:
The 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.
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.
