Exchangment of the filter
Pull with two hands carfully at the front cover, until it is
opening and lift it upwards.
Remove the front cover and the filter.
Press the filter first at the top inside and then down in
the appliance. Take care, that the polybag was removed
before. The white leashes must show to the front lower
side after the filter was inserted.
When putting the cover back on the appliance put the
lower part first inside and then press the cover gently to
the housing until it is correctly inserted.
