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
2
CO
3
). 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 165.

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.
4. Rinse the dust
fi
lters with clean water to
fl
ush all grease residue away.
5. Shake out all excess liquid by repeatedly swinging the
fi
lter to-and-fro in a centrifugal action.
6. Then allow the
fi
lters to
dry thoroughly
. Typically this can take up to 24h and more, depending on the drying conditions.
Note:
Drying time of the dust
fi
lters 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
fi
lter(s) to dry at 50°C max in a well ventilated room.
C
AUTION
:
UNDER NO CIRCUMSTANCES SHOULD WET FILTERS BE INSTALLED BACK INTO THE PROJEC-
TOR. THIS CAN HAVE SERIOUS SAFETY CONSEQUENCES AS WELL AS JEOPARDIZE THE INTERNAL OP-
TICS OF THE SYSTEM.
C
AUTION
:
Do not install/use damaged dust
fi
lters. Replace damaged dust
fi
lters immediately with new dust
fi
lters of the same type. See
