NOTICE
Damage to the compressor by liquid refrigerant
If the unit is switched off via the main switch without first switching off the control (start/stop
button or „state stop“ command), the expansion valve is closed using the battery. When the bat-
tery is discharged, the valve in this case retains its current opening degree. The open expansion
valve allows liquid refrigerant to flow into the evaporator.
