3. Check the "air in" side of the dust filter for dust and/or grease.
In case the filter is contaminated with grease wash and dry the dust filter. See cleaning procedure "Washing and drying the dust
filters", page 143.
In case the filter contains dust but doesn't feel greasy then clean these filters with compressed air. These filters are not fragile
and this method is more easier.
If an air compressor is not available, use vacuum to clean the dust filter. See procedure "Vacuum cleaning of the dust filters",
page 142.
Note: Grease on the filter 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.
Tip:
Take into account that the time needed to dry the dust filters may be 24 hours or more. For that, it's recommended to
have a second set of dust filters which can be used while cleaning the first set.
4. While the filters are removed, pivot the cooling unit to check the fans for dust. Remove that dust if necessary.
Note: Do not neglect this step. Removing dust from the fans must be checked/cleaned regularly. Pay special attention to
cleaning these fans if the cooler is installed above the projector because, due to the heat, this location has a greatest
potential for dust accumulation.
5. Insert a clean dust filter and mount cover plate.
14.4 Vacuum cleaning of the dust filters
When vacuum the dust filters?
The dust filters should be checked every month. If the filters are contaminated with dust then cleaning the filters with a vacuum
cleaner should be sufficient. In case the filters feel greasy these must be washed. See cleaning procedure "Washing and drying the
dust filters", page 143.
Grease on the filter 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 filters are removed from their slots.
Necessary tools
Vacuum cleaner with soft brush suction nuzzle.
How to vacuum-clean the dust filter?
1. Carefully vacuum the air inlet side of the dust filter. Use a vacuum cleaner with a soft brush suction nuzzle. The air inlet side of
the dust filter is the side which is surrounded with a glue edge.
Tip:
Lightly tap the filter on its dusty side to expel heavy dust contamination.
Tip:
Compressed air is also permitted to clean the filters but take care not to damage them.
Caution:
Do not damage the dust filter. Replace damaged dust filters immediately.
