Cleaning The Reflector - Christie CP2000 Technical Bulletin

8. To clean the output end of the projection lens, press the trigger of the Techspray canister
rapidly 3 times, 6 inches above the surface of the lens.
You must hold the Techspray canister vertically. Holding the canister at an angle can release
liquid refrigerant and contaminate the projector optics.
9. If the output end of the lens still appears dirty:
a) Dampen a clean, folded lint free cloth with acetone and wipe the surface of the output end
of the lens carefully with the smooth portion of the cloth that has no folds or creases.
b) Inspect the output end of the lens with a bright light and verify no streaks appear. If
streaks are present, repeat step a.
10. Reassemble the projector and connect it to AC power.

Cleaning the reflector

Clean the reflector with care. The reflector is fragile and is easily damaged.
The reflector must be cleaned with isopropyl alcohol, ACS Reagent Grade 99.9%. Other solvents can
damage the reflective coating on the reflector. If you do not have additive-free compressed air, use an
air bulb or a camel hair brush to remove the debris. If you have questions about the cleaning
methodology, contact Christie.
1. Prepare the projector for service. For more information, see Preparing the projector for service
(on page 3).
2. Remove the lamp. For removal procedures, see the projector service manual.
3. Remove the reflector. For removal procedures, see the projector service manual.
4. Put on a pair of powder-free latex gloves.
5. 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.
6. To clean the reflector, press the trigger of the canister rapidly multiple 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.
7. If the reflector still appears dirty:
a) Fold a lint free cloth and wipe the remaining dust particles off the inside of the reflector
with the smooth portion of the cloth that has no folds or creases. Do not apply pressure
with your fingers. Instead, use only the tension in the folded cloth to remove the dust.
b) If significant dust remains on the reflector surface, dampen a clean lint free cloth with
isopropyl alcohol and wipe the surface carefully. Fold a clean, dry, lint free cloth and wipe
the remaining alcohol off the reflector with the smooth portion of the cloth that has no
folds or creases.
8. Reassemble the projector and connect it to AC power.
