9- OPERATING INSTRUCTIONS

9.5 HEATING MODE (HEAT)

In heating mode, the air conditioning only allows heating.
In order to activate:
With the unit connected:
Press the MODE button.
Select the heating operation mode (HEAT).
Press the + - buttons to select the temperature setting.
Press the FAN SPEED button to select the fan speed.
- Each time the FAN SPEED button is pressed, the fan speed will be modified, increasing its power. There
are three different rates: Low , Med , high and AUTO ( indicator flashes).
- When the fan is configured in AUTO mode, the air conditioning unit automatically sets the fan speed in
accordance with the actual ambient temperature.

9.6 DEFROSTING

When the outdoor air temperature is very low and the humidity level is very high, the heat exchanger of the outdoor
unit will frost causing a negative impact on the efficiency of the heating performance. In these cases, the unit
automatically triggers a defrosting function which causes the heating operation to stop for 5 to 10 minutes::
The fans of the Indoor and the Oudoor unit are stopped.
During defrost, the unit might generate some steam. This is caused by fast defrosting and it does not
mean a performance failure.
Once the unit completes the defrosting process, it resumes the heating operation.

Press the SWING button to direct the airflow upwards or downwards. You can choose between:
- Natural flow
- swing
- Fixed wind

9.8 HORIZONTAL AIRFLOW

Danger of injury and physical damage!
The horizontal airflow can only be adjusted manually. Only do this with the unit switched off.

Direct the flaps manually to direct the airflow to the left or right.
