Product and functional description,
Defrosting If the temperature falls to below 20 °C the evaporator may start to ice up after a short
time. When, caused by a room temperature below 20 °C, the evaporator sensor registers
a temperature lower than 5 °C, it will let the unit work in dehumidification mode for fur-
ther 30 minutes. Then the compressor is stopped and the unit switches over to passive
defrosting, which means that the fan blows room air onto the evaporator coil and melts
the ice on the evaporator. When the evaporator sensor registers that the temperature is
above 5 °C, the compressor starts again.
Safety circuit 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 36 °C), the compressor stops au-
tomatically to avoid damaging it. After 45 minutes the compressor starts again automa-
tically.
