9.4 Defrost function
The defrosting of the evaporator is activated when the temperature monitored by defrost sensor is below
set point. The compressor switches off, and following a temperature rise, the frost on evaporator
becomes water. The water flows into the water pan via the drain system and will eventually evaporate.
