Maintenance and Cleaning

To help ensure optimized performance and reliability, regularly check electrical, optical and other
components as described below. Danger! Electrical SHOCK HAZARD. Disconnect from AC when
servicing. Ensure the proper protective clothing is worn during maintenance.

4.1.1 Lamp

CHECK: Every 60 days or 500 hours
Do the following (always disconnecting from AC first and wearing authorized protective clothing):
• 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 connec-
tors.
• Verify that all electrical and lamp connections are tight.

4.1.2 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 qualified 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.

Supplies Needed for Cleaning Optical Components

For cleaning off dust and/or grease, you will need:
• Soft camel-hair brush
• Dust-free blower - filtered dry nitrogen blown through an anti-static nozzle.
• Dust-free lens tissue such as Melles Griot Kodak tissues (18LAB020), Optowipes (18LAB022) or
Kim Wipes or equivalent
