Cleaning The Integrator - Christie CP2000 Technical Bulletin

Cleaning the integrator

Clean the integrator with care. The integrator is fragile and is easily damaged.
This procedure must be performed by trained Christie service personnel. 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 integrator. For removal procedures, see the projector service manual.
3. Put on a pair of powder-free latex gloves.
4. 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.
5. To clean the integrator, 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.
6. If the input end of the integrator still appears dirty:
a) Remove the input aperture.
b) Dampen a clean, folded lint free cloth with acetone and wipe the surface of the input end
of the integrator carefully with the smooth portion of the cloth that has no folds or
creases.
c) Inspect the input end of the integrator with a bright light and verify no streaks appear. If
streaks are present, repeat step b.
d) Carefully place the input aperture on the integrator rod and make sure there is enough
room around the integrator rod and aperture to prevent damage to the corners.
7. Reassemble the projector and connect it to AC power.
8. Align the integrator. For alignment procedures, see the projector service manual.
Cleaning IOS Lens 5
Lens 5 (L5) is part of the illumination optics system (IOS) in the light tube assembly located at the
vignetting aperture, directly underneath the light engine.
Consider cleaning the L5 lens only if you are attempting to resolve a loss of brightness by cleaning or
replacing the projector light engine.
1. Prepare the projector for service. For more information, see Preparing the projector for service
(on page 3).
2. Remove the light engine. For removal procedures, see the projector service manual.
3. Put on a pair of powder-free latex gloves.
4. 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.
5. To clean the L5 lens, press the trigger of the Techspray canister rapidly 3 times, 6 inches above
the optical component.
