11. Maintenance procedures
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 .
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 https://my.barco.com for the correct replacement part.
11.5 Cleaning the lens
W
ARNING
:
Make sure that the lasers are switched OFF before performing this procedure
To minimize the possibility of damage to optical coatings, or scratches to lens surfaces follow the cleaning
procedure as described here precisely.
Necessary tools
• Compressed air.
• Clean Toraysee® cloth or any micro fi ber lens cleaning cloth.
• Clean cotton cloth.
Necessary parts
Lens cleaner (e.g. Carl Zeiss lens cleaner or Purasol® or any water-based lens cleaner)
How to clean the lens?
1. Blow off dust with clean compressed air (or pressurized air cans
1
) .
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.
3. Use a dry lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
1. Pressurized air cans are not efficient if there is too much dust on the surface, the pressure is too low
