Cleaning The Integrator; Cleaning The Lamp Blower - Christie CP2420-Xe Service Manual

c) 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.

Cleaning the integrator

Clean the integrator with care. The integrator is fragile and is easily damaged.
Caution! If not avoided, the following could result in minor or moderate injury.
• This procedure must be performed by Christie qualified technicians.
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 Technical Support.
1. Prepare the projector for service.
a) Turn the lamp and projector off.
b) Allow the projector to cool for a minimum of 15 minutes.
c) Disconnect the projector from AC power.
2. Remove the integrator (on page 103).
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 three times to clear any possible impurities from the tube.
5. To clean the integrator, press the trigger of the Techspray canister rapidly three times, 152.4
mm (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.
d) If streaks are present, repeat step b.
e) 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.

Cleaning the lamp blower

The lamp blower is located at the rear of the projector, behind the lamp-access door.
1. Prepare the projector for service.
a) Turn the lamp and projector off.
