9. The device’s air dehumidification performance depends on
room design, room temperature and relative humidity of the
room air.
10. Drain the container when it is full. Then, reinsert the empty
water container so that the device can work again.
11. Tranport this device only in upright (vertical) position.
12. If the device does not work or if the operation is suddenly
interrupted for unknown reasons,
¨ see “Possible faults“.
13. When the air dehumidifier is in operation the compressor
generates waste heat and the room temperature slightly
increases. This is considered a normal process.

“Increase RH” button
4 ¨ Operating hour counter
5 ¨ “Reduce RH” button
6 ¨ Defrosting icon
7 ¨ “Fan ON” icon
8 ¨ “Water container full” icon
9 ¨ “Dehumidification mode” icon
Continuous display = dehumidfication is running
(compressor and fan on)
Flashing display = dehumidification is not
running (compressor off - fan
on)
Fault code
If the fault codes E3 – E4 – E5 are indicated in the “RH display”
¨ see “Possible faults”.
Powering up
L
An acoustic signal will sound if you connect the power
cable to an electrical socket.
A fault has occurred when this acoustic signal does not
sound. Check the power supply cable, the electrical socket
and the fuse.
Press the button to switch on the power to the air
dehumidifier.
The display 2 ¨ “RH of air” indicates the factory-set humidity of
air of 60 %. After 5 seconds the display indicates the actual
humidity of air.
The “RH” display indicates the humidity of air in a range
between 30 % and 90 %.
Shutting down
Press the button again to switch off the power to the air
dehumidifier.
Setting the humidity value
Press the button (Increase the RH setting) or (Reduce
the RH setting) to set your desired relative humidity of air.
If the set RH value is lower than 30 %, the device will
continuously dehumidify and the indicator 2 displays “CO”.
Hint: Normally, a relative humidity of air between 50 % and
60 % is sufficient to have a convenient indoor climate
and to prevent condensation on structural
components and furnishing.
L
If your desired RH value is lower than the actual RH by
3
%, the air dehumidifier will automatically start
(compressor). The icon (dehumidification) is
continuously displayed.
If your desired RH value exceeds the actual RH by 3 %,
the air dehumidifier will automatically shut down
(compressor). The
icon (dehumidification) is flashing.
Automatic defroster
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
to a temperature of +5 °C.
During defrosting, the icon is displayed on the display, the
compressor continues to run, the fan is automatically stopped.
Once the defrosting process is finished the air dehumidifier
returns to the dehumidification mode and the
icon turns off.
Operating hour counter
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.
