No refrigerant protection
When in Cooling mode and dehumidifying mode, if the compressor has worked for over 10 minutes, but
the temperature difference between the coil temperature and the room temperature is still less than 3
ºC and this temperature difference has lasted for over 30 minutes, the machine will enter into no-
refrigerant protection. This means, there is no refrigerant in the unit, so the compressor and water
spring motors will stop working, the down fan will stop running, the up fan will run at low speed and
lastly the LCD will display E3.
