this tumble dryer uses a gaseous refrigerant which is condensed by
the compressor. The refrigerant, which is brought to a higher
temperature level and liquefied by condensing, is led in a closed
circuit through the heat exchanger unit where heat exchange with the
circulating drying air takes place.

This can damage the heat pump.
After setting up the tumble dryer wait for at least one hour before
switching it on.
- The humming noises caused by the heat pump during the drying
process are normal. They do not impair the efficient functioning of
the dryer.
- The refrigerant is not flammable or explosive.
