How to vacuum-clean the dust fi lter?
1. Carefully vacuum the air inlet side of the dust fi lter. Use a vacuum cleaner with a soft brush suction nuzzle. The air inlet side of
the dust fi lter is the side which is surrounded with a glue edge.
Tip: Lightly tap the fi lter on its dusty side to expel heavy dust contamination.
Tip: Compressed air is also permitted to clean the fi lters but take care not to damage them.
Caution: Do not damage the dust fi lter. Replace damaged dust fi lters immediately.
21.5 Washing and drying the dust fi lters

AUTION
:
This procedure only concerns the washable fi lters. Under no circumstances HEPA fi lters (High-
ef fi ciency particulate arresting) should be washed. An used HEPA fi lter must be systematically replaced.
About fi lter washing and drying
For environments where popcorn grease and such can contaminate the fi lters, Barco advises the client to purchase one extra set
of fi lters to cover drying time, as well as taking following extra precautions and instructions pertaining to fi lter cleaning and drying.
Cleansing agent
To clean sticky, greasy dust fi lters we suggest usage of Sodium carbonate crystals (Na

). Sodium carbonate (Often called
washing soda , soda crystals , or sal soda in the detergent section of stores) is widely used to effectively remove oil, grease, alcohol
stains … The product itself is relatively safe, sodium carbonate is used in toothpastes and as a food additive (E500). Potential
Hazards are described in the section "Hazards", page 287.

Sodium carbonate crystals.
This cleaning procedure assumes that the fi lters are already removed from their slots.
Take into account that the time needed to dry the dust fi lters may be 24 hours or more. For that, it’s recom-
mended to have a second set of dust fi lters which can be used while cleaning the fi rst set.
Necessary tools
• Bucket with hot water.
• Sodium carbonate, 30 gram (handful) per liter hot water.
How to wash and dry the dust fi lters?
1. Make a solution with a ratio of 30 gram (a handful) sodium carbonate to 1 liter hot water .
2. Soak the dust fi lters in the solution for 30 to 60 minutes . The grease should be dissolved after 1 hour.
3. If the dust fi lter is still clogged repeat this procedure from step 1.
