Filters
Clean the filters every two weeks. If the filters become blocked by dust, the efficiency of the
air conditioner will be reduced.

Remove the air filters (items 7 and 11) on the rear of the unit.

Run a vacuum cleaner lightly over the surface of the filters to remove dust. If the filters
are exceptionally dirty wash them in warm water and a mild detergent and allow to dry
thoroughly before refitting.
Note: Do not operate the air conditioner without the filters.
