Cooling; Replacing Modules - Christie CP2420-Xe Service Manual

A Horizontal offset
B Horizontal boresight bolt
C Anchor bolt
D Vertical offset
For the best optical performance and to minimize keystone error, use offset rather than aiming
to center the image in off-axis installations. Avoid extreme tilts or offsets. Corner vignettes on
a white test pattern indicate extreme offset that should be corrected by using mechanical
alignment.

Cooling

The high-intensity lamp and electronics rely on a variety of cooling components to reduce internal
operating temperatures. You must do regular inspection and maintenance of the entire cooling system
to prevent overheating and sudden projector failure and helps to ensure reliable operation of all
projector components over time.

Replacing modules

To ensure you have the correct module, check the module markings and parts lists. To ensure you
replace the projector module correctly, check the relevant disassembly and replacement procedures.
Replace components with exact equivalents or Christie-approved replacement parts. Failure to do so
may result in unsafe operation.
