Lightning / Drop / Triangle / Fire
If the unit is switched off and restarted by connecting and disconnecting power, the LEDs will light up in turn
before the operation mode is indicated on the display.

4.5 Defrosting

If the temperature falls to below 20ºC the evaporator may start to ice up after a short time. When the evaporator
sensor registers a temperature lower than 5ºC, it will let the unit work in dehumidification mode for further 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 5ºC, the compressor starts again.

4.6 Re-heating coil

The control of the dehumidifier has an option for connecting a re- heating coil. The heating coil is connected to an
extra PCB and the terminals 23/24.

4.7 Safety circuit

If the temperature in the dehumidifier increases to a temperature of more than 55ºC (in case of fan failure or room
air temperature higher than 36ºC), then the compressor stops automatically to avoid damaging it. After 45 minutes
the compressor starts again automatically.

5. Maintenance

The dehumidifier requires very little attention for trouble free running. All the necessary safety and control
functions have been built in. The fan motor(s) and the compressor have permanent lubrication and require no
particular maintenance.

5.1 Cleaning of the dehumidifier

The air inlet filter is to be cleaned once a month. The filter is placed in a stand behind the grille in the air inlet duct.
Remove the grill from the duct and take out the filter. The filter is washed in tepid soapy water or vacuum cleaned.
Put the filter back in the filter stand and fasten the grille to the duct.
Once a year the front should be removed in order to check the inside of the dehumidifier. If the dehumidifier is
dirty it should be vacuum cleaned. The condenser in particular should be thoroughly vacuumed. If the lamella
evaporator is badly soiled, it may be washed in tepid soapy water.

6. Faults and how to remedy them

The dehumidifier does not work, no light in the LEDs on the display:
1. Check the external fuses.
