Maintenance And Cleaning; Guidelines For Cleaning - Christie HS 2K Series Service Manual

• Ensure the projection system is securely mounted or immobilized to prevent unintended
movement or misalignment of the projections.
• Temporary show installations containing Risk Group 3 laser-illuminated projectors may be
installed by Christie or sold or leased only to valid laser light show variance holders (laser light
show manufacturers) for image projection applications. Such manufacturers may currently hold
a valid variance for production of Class IIIb and IV laser light shows and/or for incorporation of
the Risk Group 3 laser-illuminated projectors into their shows. This requirement applies also to
dealers and distributors of these laser-illuminated projectors.
• The Christie Laser Projection System Installation Checklist must be fully completed after the
installation and sent to lasercompliance@christiedigital.com. A copy can remain on-site. This
checklist can be found as a separate document in the accessory box with the manual.
If installing in the US states of Arizona, Florida, Georgia, Illinois and Massachusetts, go to
www.christiedigital.com for additional regulatory requirements.

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.
Always power down and disconnect/disengage all power sources to the projector before servicing or
cleaning the lens or before any of the projection head covers or doors 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.
Notice. If not avoided, the following may result in equipment or property damage.
• Avoid touching optical elements.
• Always wear clean, lint-free gloves when handling the product.
