DESCRIPTION OF FUNCTIONS

Switch on the unit. The green pilot lamp illuminates. The ventilation fan
sucks in the moist ambient air via the air filter, the evaporator and the
condenser. Heat is extracted from the ambient air at the cold evaporator.
The air is cooled to below the dew point, and the water vapour contained
in the air is accumulated as condensate water on the evaporator fins and
then drops down into the water tank. As a low temperature of ambient
air is sucked, the water vapour becomes to hair-frost on the evaporator
fins. When the temperature sensor measures a specific low value of the
evaporator’s surface, a timer is activated with a delay of about 30 minutes.
If during this period the evaporator’s temperature does not rise again, the
refrigeration cycle will switch to hot gas defrost after the time reach. Dur­ing the defrost cycle, the ventilation fan is off. As it has defrosted and the
