Cleaning The Lens; Cleaning The Reflector; Other Components - Christie CP2000-XB Setup Manual

Section 4: Maintenance
• Lens cleaning solution such as Melles Griot Optics Cleaning Fluid 18LAB011 or equivalent. For lens only
• Methanol. For reflector only
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfibre such as Melles Griot 18LAB024 or equivalent.

Cleaning the Lens

IF DUSTY:
Brush most of the dust off with a camel-hair brush and/or blow dust away with compressed air.
Fold a microfibre cloth smooth and gently wipe remaining dust particles off the lens. Make sure to wipe evenly
with the smooth portion of the cloth that has no folds or creases. Do not apply pressure with your fingers—use
the tension in the folded cloth itself to collect the dust.
If significant dust is still bound to the surface, dampen a clean microfibre cloth with lens cleaning solution
(damp, not dripping). Wipe gently until clean.
IF FINGERPRINTS, SMUDGES, OIL:
1. Brush most of the dust off with a camel-hair brush and/or blow dust away with compressed air.
2. Roll a lens tissue around a swab and soak in lens cleaning solution. Tissue should be damp but not
dripping.
3. Gently wipe the surface using a figure-8 motion. Repeat until blemish is removed.

Cleaning the Reflector

IF DUSTY:
Brush most of the dust off with a camel-hair brush and/or blow dust away with compressed air.
1. If some dust remains, just leave as is—air circulating at the lamp is unfiltered, so some dust is inevitable.
Avoid unnecessary cleaning.
IF FINGERPRINTS, SMUDGES, OIL:
1. First brush dust off with a camel-hair brush and/or blow dust away with compressed air.
2. Fold a clean microfibre cloth and dampen with methanol. Make sure to wipe evenly with the smooth
portion of the cloth that has no folds or creases. Do not apply pressure with your fingers—use the solution
in the cloth to collect the dirt.

4.1.3 Other Components

In a normal operating environment check, clean and treat the following components every 6 months or so to
help ensure proper lamp and projector function:
LAMP FAN - A clogged lamp fan impeller or motor can reduce air flow, leading to possible overheating and
failure of the lamp. Clean/treat the impeller as follows:
1. Vacuum loose dirt from the lamp fan impeller.
2. If necessary, use a brush with hot water and suitable detergent.
Important! Do not bend the impeller blades or loosen the balancing weights.
IGNITER - Clean the high voltage terminal and insulator to remove accumulated dust or dirt.
