• Lens cleaner (e.g. ZEISS lens cleaner, Purosol™ or other water based lens cleaner products)
How to clean the lens?
1. Blow off dust with clean compressed air (or pressurized air cans
6
) .
2. Clean with lens cleaner together with a clean lens cleaning cloth to remove the dust and contamination.
Use big wipes in one single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into
the coating.
3. Use a dry lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
4. If there are still fingerprints on the surface, wipe them off with lens cleaner together with a clean lens
cleaning cloth. Polish again with a dry one.
If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty
cloth.
11.5 Cleaning the exterior of the projector
How to clean the exterior of the projector ?
1. Switch off the projector and unplug the projector from the mains power net.
2. Clean the housing of the projector with a damp cloth. Stubborn stains may be removed with a cloth lightly
dampened with a mild detergent solution.
11.6 Check cooling liquid level
Only for a DP2K-15C and a DP2K-20C projector.
What should be done ?
The projector is liquid cooled. It is important that the liquid level is checked at regular intervals. We advise to
check every 3 months. The liquid level must be between min. and max. Significant drop in liquid level indicates
a major leakage and requires immediate attention.
How to check
1. Remove the side cover on the light processor side, see “Removal of the side cover”, page 126.
2. Look through the small window in the security cover of the light processor and check the liquid cooling
level in the reservoir.
Maintenance
6. Pressurized air cans are not efficient if there is too much dust on the surface, the pressure is too low
