2. Wipe lenses in a one single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave the cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the fi rst indication of a dirty cloth.
C
AUTION
:
Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the
cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Other lenses can also be cleaned safely with this Toraysee TM cloth.
11.4 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.
11.5 Check cooling liquid level
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. Signi
fi cant drop in liquid level indicates a major leakage and requires immediate
attention.
How to check
1. Remove the left side cover (Light Processor side). see "Removal of the side cover", page 87.
2. Check the liquid cooling level in the reservoir.

Cooling liquid check
If the current liquid cooling level is somewhere between Min and Max , then no action should be taken.
If the current liquid cooling level is approaching the Min level point, than check for leakage in the cooling system prior starting
the re fi ll procedure.
If you cannot see the level, open the fi ller cap and shine a torch into the reservoir
