Cleaning projector optics

If the recommended cleaning supplies described in the procedures are unavailable in your area,
contact Christie service. For improving brightness and contrast, the procedures are organized from
most to least effective.
Notice. Failure to comply with the following may result in property damage.
• Always wear powder free latex gloves when handling and cleaning projector optics.
• Handling optics increases the risk of damage. You should only clean optics when necessary.
• Only use solvents if dirt remains after dusting with compressed air.
• Do not reuse lens tissues. Use a clean tissue for each cleaning attempt.
• Handle optics by their edges.
• When using Techspray 1671-10S do not shake the can prior to use.

Preparing the projector for service

1. Turn the lamp and projector off.
2. Allow the projector to cool for a minimum of fifteen minutes.
3. Disconnect the projector from AC power.

Cleaning the light engine prism

If the entire light engine requires cleaning, contact Christie support.
If you cannot access additive free compressed air, use an air bulb or a camel hair brush to remove
dust and debris. If you have questions about the cleaning methodology, contact Christie.

The prism is easily damaged. Handle with care.
3. Clean the prism with Techspray 1671-10S:
a. Firmly attach the red output tube to the output nozzle on the Techspray 1671-10S
canister.
b. While pointing the output tube away from the prism, press the trigger rapidly 3 times to
clear contaminants from the output tube.
