Remove the front panel by screwing off two screws on top of the dehumidifier. Lift the front panel
vertically upwards and then pull it horizontally away from the unit.
The control of the unit is located in a box on top of the compressor. To get access to the control you have
to screw off the screws on front of the box lid. Push the lid towards the rear of the dehumidifier and then
pull it away from the box.

Power is connected to the unit in accordance with the nameplate. Please refer to the wiring diagrams on
the pages 31-32.

4. Operation

4.1. Built in hygrostat

The dehumidifier is controlled by a built-in hygrostat that is set to approx. 60% RH. When the hygrostat
registers a relative humidity of more than 60%RH, the compressor and the fan automatically switch on
and the dehumidifier starts to dehumidify. The hygrostat is located next to the evaporator at the bottom of
the compressor housing.
If you want to set the hygrostat at a lower relative
humidity than 60%, the set screw has to be turned
clockwise.
We recommend installing an external hygrostat if
you want to change/adjust the setting of relative
humidity very often.

4.1.1. Connection of external hygrostat

Disconnect the built-in hygrostat from the terminals
21/22 and connect the external hygrostat instead.
The hygrostat cable is led out through the bottom of
the unit and the hygrostat is then fixed to a wall in
an appropriate place. The outlet for the external hygrostat is 12 V.
NOTE! All electrical connections must be
made in
accordance with local power supply
NOTE! If the air humidity is below 60%RH, the unit
will not start when the power is connected.
