At a room temperature under 20 °C not only condensation
water is generated on the cold evaporator surface, but also ice.
This ice blocks the heat exchanger so that the air flow is
impeded. The built-in automatic defroster removes the ice from
the evaporator. This allows a dehumidification operation down
not
to a temperature of +5 °C.
During defrosting, the
compressor continues to run, the fan is automatically stopped.
Once the defrosting process is finished the air dehumidifier

The air dehumidifier is equipped with an
operating hour counter.
The number of hours during which the device was in operation
in the past is displayed after the dehumidifier is turned on. The
amount of time during which the device remains on will be
added to the already elapsed time.
The water collecting container of the air dehumidifier is
equipped with a float switch which turns off the device when the
collecting container is full.
After 45 seconds, compressor and fan will automatically
stop, and an acoustic signal will sound. The
