2. Pull out the dust fi lter.
3. Check the “air in” side of the dust fi lter for dust and/or grease .
In case the fi lter is contaminated with grease wash and dry the dust fi lter. See cleaning procedure "Washing and drying the dust
fi lters", page 275.
In case the fi lter contains dust but doesn’t feel greasy then vacuum clean the dust fi lter. See procedure "Vacuum cleaning of the
dust fi lters", page 274.
Note: 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.
Tip: Take into account that the time needed to dry the dust fi lters may be 24 hours or more. For that, it’s recommended to
have a second set of dust fi lters which can be used while cleaning the fi rst set.
4. Slide in a clean dust fi lter.
Warning: UNDER NO CIRCUMSTANCES SHOULD WET FILTERS BE INSTALLED BACK INTO THE COOLING UNIT.
5. Place the cover plate back on its location and drive in both fi xation screws.
21.4 Vacuum cleaning of the dust fi lters
When vacuum the dust fi lters?
The dust fi lters 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 275.
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 their slots.
