Maintenance and Cleaning

To help ensure optimized performance and reliability, regularly check electrical, optical and other
components as described below. Warning! SHOCK HAZARD. Disconnect from AC at BOTH wall
breakers.

4.1.1 Electrical

Do the following every 60 days or 500 hours (always disconnecting from AC first):
• Check the contact surfaces of positive (anode) 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 or other marks are obvious. Never touch an optical surface with your bare hand-
always wear latex lab gloves.

When to Check

LENS:
A small amount of dust or dirt on the lens has minimal effect on image quality-to avoid the risk of
scratching the lens, clean the lens only if absolutely required. See below.
LAMP REFLECTOR:
Inspect the mirror surface (reflector) for cleanliness only during a lamp replacement, when the lamp is
out. If necessary, clean as described below-ensure to wear protective clothing while inspecting or
cleaning. Note that color on the reflector surface may vary-this is normal.

Supplies

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
