Noise during operation (only for compact system)
To keep the selected temperature constant when cooling, from time to time, the hot or cold combiplate
switches the compressor of the cooling unit on. The sounds which occur are related to functionality. They
will reduce automatically as soon as the unit has reached operating temperature. The humming noise
comes from the compressor.
