4) Put the tank properly back into place.
The appliance is not able to dehumidify
the room enough.
1) The air inlet or outlet are obstructed (by
curtains, objects, walls, etc.).
2) The set humidity level is not low enough.
3) The windows and doors of the room are
not closed.
4) The room temperature is either too low
(lower than 5°C) or too high (above 35°C).
5) The air lter is clogged.
1) Free the air inlet and outlet.
2) Appropriately adjust the humidity level.
3) Close all windows and doors.
5) Clean the air lter.
The appliance is very noisy. 1) The air lter is clogged.
2) The appliance is inclined.
3) The appliance is resting on a non-at
surface.
1) Clean the air lter.
2) 3) Reposition the appliance.
‘P1’ appears on the display. Anti-frost function active. Wait until the defrosting function ends. ‘P1’ will
disappear automatically.
‘P2’ appears on the display. Tank full. Empty the tank and put it correctly back in
place.
‘AS’ appears on the display. The humidity sensor is disconnected or has
short-circuited.

(1) Relative to operation at 30°C and 80% relative humidity.
(2) Refrigerant loss contributes to climate change. In case of their release into the atmosphere, refrigerants with lower global warm-
ing potential (GWP) have less impact on global warming compared to refrigerants with a higher GWP. This appliance contains a
refrigerant uid with a GWP of 1,300. In other words, if 1 kg of this refrigerant uid were released into the atmosphere, the impact
on global warming would be 1,300 times greater compared to 1 kg of CO
2
, over a period of 100 years. In no case whatsoever
must the user attempt to intervene on the refrigerant circuit or dismantle the product. In case of need, please contact a qualied
professional.
