Maintenance and Cleaning
ELECTRICAL SHOCK HAZARD! Disconnect from AC when servicing. Ensure the
proper protective clothing is worn during maintenance.
To help ensure optimized performance and reliability, regularly check electrical, optical and other components
as described below.
2.6.1 Lamp
Check: Every 60 days or 500 hours
Do the following (always disconnecting from AC first, and wearing authorized protective safety gear):
• Check the contact surfaces of anode (positive) and cathode (negative) connections for cleanliness.
• Clean electrical contact surfaces as necessary to prevent contact resistance from scorching connectors. Use
appropriate contact cleaner.
• Verify that all electrical and lamp connections are tight.
2.6.2 Optical
Unnecessary cleaning of optics can be more harmful than helpful, increasing the risk of degrading delicate
coatings and surfaces. In this projector, check only the lens and lamp reflector. Maintenance of other optical
components requires a Christie authorized service technician. Check these components periodically in a clean,
dust-free environment using a high-intensity light source or flashlight. Clean them only when dust, dirt, oil,
fingerprints or other marks are obvious. Never touch an optical surface with your bare hands. Always wear
latex lab gloves.
