How to wash and dry the dust filters?
1.
Make a solution with a ratio of 30 gram (a handful) sodium carbonate to 1 liter hot water.
2.
Soak the dust filters in the solution for 30 to 60 minutes. The grease should be dissolved after 1 hour.
3.
If the dust filter is still clogged repeat this procedure from step 1.
4.
Rinse the dust filters with clean water to flush all grease residue away.
5.
Shake out all excess liquid by repeatedly swinging the filter to-and-fro in a centrifugal action.
6.
Then allow the filters to dry thoroughly.
Note: Drying time of the dust filters can be up to 24h or more. Drying time can be shorter when being
done in a well-ventilated area.
Tip: To speed-up drying, allow the filter(s) to dry at 50°C max in a well ventilated room.
CAUTION: UNDER NO CIRCUMSTANCES SHOULD WET FILTERS BE INSTALLED BACK INTO
THE PROJECTOR. THIS CAN HAVE SERIOUS SAFETY CONSEQUENCES AS WELL AS
JEOPARDIZE THE INTERNAL OPTICS OF THE SYSTEM.
CAUTION: Do not install/use damaged dust filters. Replace damaged dust filters immediately with
new dust filters of the same type. See

How to clean the lens?
1.
Blow off dust with clean compressed air (or pressurized air cans
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.

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.
