Condensate present or water loss on the indoor unit.
- The presence of condensate is due to the high level of humidity
in the room
- Check the connection of the condensate drain tube.
- Make sure the condensate drain is not obstructed.
Water loss on the outdoor unit
- In Heating mode, condensate is normal on the outdoor heat
exchanger.
- In Heating mode with low temperatures, the condensate tends
to freeze. This frost is automatically removed by the unit by
activating a defrost cycle. In this case, the loss of water from the
condensate drain is normal.
No air discharging from the indoor unit.
- In Heating mode, to prevent jets of cold air, ventilation is active
only when the indoor unit heat exchanger is hot enough.
- In the Dehumidification mode, the ventilation of the indoor unit
may switch off to keep under control the inside temperature.
PROBLEM
ATTENTION: Do not attempt to repair the unit. An incorrect intervention could cause electric shocks, therefore, please
contact the local After Sales Service after removing the power supply.
To reduce cost and time, before the local After Sales Service, carry out the following controls.
