Maintenance And Cleaning; Guidelines For Cleaning - Christie CineLife+ CP4415-RGB Service Manual

Maintenance and
cleaning
Maintain the cleanliness of all internal components during any service procedure. All of the projector
optics must remain free of contaminants to perform at the level specified. Even a small amount of dust
or a fingerprint may degrade the image or cause a noticeable reduction of brightness.
In environments where dust, smog, dirt, and other contaminants are higher than normal, Christie
strongly recommends performing more frequent maintenance than your maintenance schedule
indicates.
Always power down and disconnect/disengage all power sources to the projector before servicing or
cleaning the lens or before any of the projection covers or doors (if applicable) are loosened and
removed. If the seal is broken while the intake fans are still operating, internal components are
immediately vulnerable to contamination from inbound particles.
Caution! If not avoided, the following could result in minor or moderate injury.
• Observe all electrostatic precautions. Use a grounded wrist strap and insulated tools when
handling, servicing, or cleaning electronic assemblies.
Notice. If not avoided, the following could result in property damage.
• Avoid touching optical elements.
• Always wear clean, lint-free gloves when handling the product.
