Cleaning The Reflector; Cleaning The Integrator - Christie CP2208 Service Manual

Cleaning the reflector

The reflector must be cleaned with Isopropyl Alcohol Reagent Grade (ACS) 99.9%. Other solvents
can damage the reflective coating on the reflector. Clean the reflector with care. The reflector is
fragile and is easily damaged.
If you cannot access 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. See
2. Remove the lamp. See
3. Remove the reflector. See
4. Put on a pair of powder free latex gloves.
5. Clean the reflector 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 projector optics, press the trigger rapidly 3
times to clear contaminants from the output tube.
c. Press the trigger of the Techspray 1671-10S canister rapidly multiple 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.
6. 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 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 Reagent Grade (ACS) 99.9% 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.
7. 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. This procedure must
be performed by trained Christie service personnel.
If you cannot access 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.
