Maintenance

This section provides information and procedures for performing projector maintenance. You should
read this section in its entirety before performing maintenance activities. When you perform
projector maintenance, obey all warnings and precautions.

Inspecting ventilation

Vents and louvers in the projector covers provide ventilation, both for intake and exhaust. Never
block or cover these openings. Do not install the projector near a radiator, heat register, or within
an enclosure. To ensure adequate airflow around the projector, keep a minimum clearance of 50cm
(19.69") on the left and right sides of the projector.
It is recommended that you periodically check that the LVPS fan is operating. It is not monitored
and a failure can cause damage to the projector.

Inspecting the lamp

Danger! Failure to comply with the following results in serious injury.
Always disconnect from AC and wear authorized protective safety gear.
• Check the contact surfaces of the anode (positive) and the cathode (negative) connections for
cleanliness.
• Clean electrical contact surfaces every 5000 hours or after two lamp changes to prevent contact
resistance from scorching connectors. Use an approved contact cleaner.
• Verify that all electrical and lamp connections are secure.

Inspecting and cleaning optics

The procedures in this section 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.
