15.3 Vacuum cleaning of the dust fi lters
When vacuum 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 "Washing and
drying the dust fi lters", page 135.
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. For removal and installation of
the fi lters see procedures "Check the large dust fi lter", page 130, and "Check the small dust fi lter", page 132.
Necessary tools
Vacuum cleaner with soft brush suction nuzzle.
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.
