Maintenance

This section provides information and procedures for performing projector maintenance. Read
through this section in its entirety before performing maintenance activities. When performing
projector maintenance, obey all warnings and precautions.
Never attempt to access the lamp compartment while the lamp is on. Wait at least 10
minutes after the lamp turns off before powering down, disconnecting from AC and opening
the lamp door.
The arc lamp operates at a high pressure that increases with temperature. Failure to allow
the lamp to sufficiently cool before handling, increases the potential for an explosion causing
personal injury or property damage.
Always wear manufacturer approved protective safety clothing (gloves, jacket, face shield)
whenever the lamp door is open or when handling the lamp.
When accessing the restricted access location for projector service or maintenance, avoid
exposure to the projector beam path by making sure to either:
• Power off the projector and disconnect from AC.
• Shutter the lamp to avoid emissions from the front aperture.
Danger! Failure to comply with the following results in death or serious injury.
ELECTRICAL SHOCK HAZARD! Always turn off, disconnect, and disengage all power sources
to the projector before servicing.
