This cleaning procedure assumes that the filters are already removed from their slots.
Take into account that the time needed to dry the dust filters may be 24 hours or more. For that, it's
recommended to have a second set of dust filters which can be used while cleaning the first set.
Required tools
• Bucket with hot water.
• Sodium carbonate, 30 gram (handful) per liter hot water.
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 https://my.barco.com for the correct replacement part.
