defrosted
Ice formation
on the
evaporator
Active, demand-controlled defrosting is incorporated into the electronic control. The
evaporator coil is defrosted by means of hot refrigerant bypassing the condenser and
being fed through the evaporator.
If the temperature falls to below 20 °C the evaporator may start to ice up after a short
time. When the evaporator sensor registers a temperature lower than 5 °C it will let the
unit work in dehumidification mode for further 30 °minutes before switching over to
defrosting mode.
If the temperature in the dehumidifier increases to a temperature of more than 55 °C (in
case of fan failure or room air temperature higher than 30 °C), then the compressor
stops automatically to avoid damaging it. After 45 °minutes the compressor starts again
automatically.

Function
The LEDs 4 and 5 light up during defrosting of the
evaporator. In defrosting mode the compressor is
working and the fan is stopped. When the evaporator
sensor has registered a temperature higher than 5 °C
the LEDs 4 and 5 are turned off
The defrost function allows icing up for 30 minutes
before defrosting of the evaporator coil is activated
