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.

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.

6.3.5 Clean 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.
