Cleaning The Lens; Cleaning The Lamp Reflector - Christie Solaria CP2220 User Manual

4.4.3 Cleaning the Lens

CHECK: Periodically
A small amount of dust or dirt on the lens has minimal effect on image quality. To avoid the risk of scratching
the lens, clean only if absolutely necessary.
Dust:
1. Brush most of the dust off the lens with a camel-hair brush and/or blow dust away with compressed air.
2. 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 dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with coated optics cleaning
solution (damp, not dripping). Wipe gently until clean.
Fingerprints, smudges, or oil present:
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 it in the coated optics cleaning solution. Tissue should be damp
but not dripping.
3. Gently wipe the surface using a figure eight motion. Repeat this motion until the blemish is removed.

4.4.4 Cleaning the Lamp Reflector

CHECK: Check during each lamp replacement
Inspect the mirror surface (reflector) for cleanliness only during a lamp replacement when the lamp is already
removed. Wear protective clothing while inspecting or cleaning. It is normal for the color on the reflector
surface to vary.
Dusty:
1. Brush most of the dust off the lens with a camel-hair brush and/or blow dust away with compressed air.
2. If some dust remains, leave as is. Since the air circulating at the lamp is unfiltered, some dust is inevitable.
Avoid unnecessary cleaning.
Fingerprints, smudges, or oil is present:
1. Brush most dust off the lens 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.
