Clean the fan blades every other year using compressed air or a brush. Each fan blade should
be clean in order to keep the fan balanced. Gently spin the fans and listen for bearing noise. If
so the fan are worn out, and needs to be replaced.
WARNING: Be careful not to remove the metal balancing pieces mounted on the fan blades.
Check the heat exchanger for dust and dirt every other year. Clean the heat exchanger with
a soft brush and a vacuum cleaner at all four inlets. In special cases, e.g. if there are signs of
accumulated, dirty condensate in the heat exchanger, it may be necessary to remove the
exchanger from the unit and clean the exchanger with soapy water.
Turn the four locks, and the heat exchanger can be removed.
