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.

4.3.1 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 connectors.
• Verify that all electrical and lamp connections are tight.

4.3.2 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.
Optical Component Cleaning Supplies
• 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), Kim Wipes
or equivalent
• For lens only. Lens cleaning solution such as Melles Griot Optics Cleaning Fluid 18LAB011 or equivalent
• For reflector only. Methanol
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfibre such as Melles Griot 18LAB024 or equivalent

4.3.3 Cleaning the Lens

CHECK: Periodically
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 only if absolutely necessary.
Dust:
1. Brush most of the dust off the lens with a camel-hair brush and/or blow dust away with compressed air.
2. Fold a microfibre cloth smooth and gently wipe remaining dust particles off the lens. Make sure to wipe
evenly with the smooth portion of the cloth that has no folds or creases. Do not apply pressure with your
fingers - use the tension in the folded cloth itself to collect dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with coated optics cleaning
solution (damp, not dripping). Wipe gently until clean.
