Cleaning The Projection Lens - Christie CP2208 Service Manual

Cleaning the projection lens

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.
1. Prepare the projector for service. See
2. Put on a pair of powder free latex gloves.
3. Remove the projection lens from the projector and place it on a flat, stable surface. See

4. Clean the input end of the lens 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 input end of the lens, press the trigger
rapidly 3 times to clear contaminants from the output tube.
c. Press the trigger of the Techspray 1671-10S canister rapidly 3 times 6 inches above the
optical component.
You must hold the Techspray 1671-10S canister vertically. Holding the canister at an
angle can release liquid refrigerant and contaminate the projector optics.
5. If the input end of the lens still appears dirty:
a. Dampen a clean, folded lint free cloth with Acetone Reagent Grade and wipe the surface
of the input end of the lens carefully with the smooth portion of the cloth that has no
folds or creases.
b. Inspect the input end of the lens with a bright light and verify no streaks appear. If
streaks are present, repeat step a.
6. Reinstall the lens.
