9.3 Vacuum cleaning of the dust filter foam

When vacuum the dust filter foam

If the dust filter foam is contaminated with dust then cleaning the foam with a vacuum cleaner should be sufficient. In case the dust filter foam feels greasy then it must be washed. See cleaning procedure “Washing and drying the dust filter foam”.

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.
Prerequisites

This procedure assumes that the dust filter foam is removed from the dust filter holder. See procedure “Replacing the dust filter”.

Required tools

Vacuum cleaner with soft brush suction nuzzle.

How to vacuum-clean the dust filter foam

  1. Carefully vacuum the air inlet side of the dust filter foam. Use a vacuum cleaner with a soft brush suction nuzzle.

    Tip: Lightly tap the filter foam on its dusty side to expel heavy dust contamination.
    Tip: Compressed air is also permitted to clean the filter foam but take care not to damage the foam.
    Caution: Replace a damaged dust filter foam immediately.
