Installation Safety and Warning Guidelines

WARNING
• QUALIFIED TECHNICIAN REQUIRED for all installations. This product must be installed in a
restricted access location.
• Never operate the projector without the covers in place.
• The projector uses a high-pressure lamp that may explode if improperly handled. Always
wear manufacturer approved protective safety clothing (gloves, jacket, face shield) when-
ever the lamp door is open or when handling the lamp. Only qualified technicians should
install projector lamps.
• To prevent the projector from tipping unexpectedly, you must install the safety strap on the
rear of the projector.
• Four or more people are required to safely lift and carry one projection head a short dis-
tance. Remove the lamp before transporting the projector.
• Keep the projector level when you lift or transport it. Avoid tilting the projector to the
right. This can introduce an air bubble into the coolant hoses that can result in an air lock
and the overheating of the projector.
• Perform a automatic LampLOC™ adjustment when you move, level, or install a new lamp in
the projector.

Position the Projector

1. If you are installing the projector in the optional rack stand (P/N 108-282101-02) follow the instructions
provided with the rack stand to install it.
2. Position the projector at an appropriate throw distance (projector-to-screen distance) and vertical position.
Ideally, center the projector with the theatre screen. If space is limited, you can aim the projector slightly
off-center. This increases side keystoning, but reduces the horizontal lens offset required.
NOTE: Unlike film projectors, it is best to keep the projector lens surface as parallel to the screen as pos-
sible, even if significantly above the screen center. When a particularly short throw distance combines with
a very wide screen, you may have to forfeit some aim and stay more parallel to the screen. In such cases,
some lens offset can reduce the keystone distortion.
