Preparing The Projector For Service; Cleaning The Light Engine Prism; Cleaning The Uv Filter - Christie CP2000 Technical Bulletin

Preparing the projector for service

Before performing any service procedure, ensure that the projector is turned off and disconnected
from power.
• Turn the lamp and projector off.
• Allow the projector to cool for a minimum of 15 minutes.
• Disconnect the projector from AC power.

Cleaning the light engine prism

If the entire light engine requires cleaning, contact Christie technical support.
If you do not have 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.
1. Prepare the projector for service.
2. Remove the prism and set it on a clean, lint free cloth. For removal procedures, see the
projector service manual.
The prism is easily damaged. Handle with care.
3. To prepare the Techspray 1671-10S canister for use, firmly attach the red output tube to the
output nozzle on the canister, point the canister away from the optical component, and press
the trigger rapidly 3 times to clear any possible impurities from the tube.
4. To clean the light engine prism, press the trigger of the Techspray canister rapidly 3 times, 6
inches above the optical component.
You must hold the Techspray canister vertically. Holding the canister at an angle can release
liquid refrigerant and contaminate the projector optics.
5. If the prism still appears dirty:
a) Put on a pair of powder-free latex gloves.
b) Dampen a clean, folded lint free cloth with acetone and wipe the surface of the prism
carefully with the smooth portion of the cloth that has no folds or creases. Do not apply
pressure with your fingers. Use only the tension in the folded cloth.
c) Inspect the prism surface with a bright light and verify it is streak free. If streaks are
present, repeat step b.
6. Reassemble the light engine and the projector.
7. Connect the projector to AC power.
