11.3 Vacuum cleaning of the dust fi lters
When to vacuum clean the dust fi lters?
The dust fi lters of the projector should be checked every month. If the fi lters are contaminated with dust then cleaning the fi lters
with a vacuum cleaner should be suf fi cient. In case the fi lters feel greasy these must be washed. See cleaning procedure "Vacuum
cleaning of the dust fi lters", page 96.
Grease on the fi lter can build up after several months in an environment contaminated with greasy air. Note
that areas where popcorn is consumed are subject to greasy air.
This procedure assumes that the dust fi lters are removed from the projector.
Necessary tools
Vacuum cleaner with soft brush suction nozzle.
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 nozzle. 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 use compressed air inside the booth area. Bring the dust fi lters outside the building to blow off the dust.
Caution: Do not damage the dust fi lter. Replace damaged dust fi lters immediately.
11.4 Washing and drying the dust fi lters
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

CO

). 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 107.
