Cleaning the dehumidifier

Once a year the unit should be cleaned internally. Remove filter and loosen screws (1) and (2).
Then handle and cover panels are detached. The inside of the unit is now accessible for vacuum
cleaning. Especially the condenser and the evaporator have to be vacuum cleaned with care. If the
evaporator is very dirty it can be washed with tepid soapy water, but it has to be done with much
care, as the fins will easily become damaged. The drip tray under the evaporator may also need
cleaning, in order not to restrict drainage of the condensate.
