7.3.2

Defrosting when heating water

When the heat pump is running, if the evaporator is frozen owing to a low­
er room temperature, the system defrosts automatically to maintain effi­
cient performance (approx. 5-15 min). During defrosting, the compressor
shuts down but the fan motor continues to run.
