Solution
Indoor air cools rapidly. Wait for the
indoor temperature and humidity to fall
and the mist to disappear.
The temperature cannot be adjusted in
automatic mode. Change the operating
mode if you want to adjust the
temperature.
The available temperature range is: 16 –
30°C.
Wait for the voltage to return to normal.
Clean the filter.
Adjust the temperature to within the
available range.
Close any doors and windows.
Eliminate the odour source.
Clean the filter.
Disconnect the power supply and then
reconnect it. Turn the unit on again.
Steam production when defrosting in
heat mode is a normal phenomenon.
The noise is produced by the refrigerant
flowing inside the unit (normal
phenomenon).
It is the sound of the friction caused by
the expansion and/or contraction of the
panel or other parts due to temperature
changes.
