Common Fault Code Processing Method:
1 The battery power is insufficient and under voltage E2
() Check the battery for aging and replace it
() If the battery is not fully charged it needs to be
charged
() Connect the negative pole of the power line to
the metal or the generator reconnect the wirings
or harness
2 Pressure Fault (System leakage) E4:
-Refrigerant leakage or poor heat dissipation
3 Sensor Fault E0 or E1:
() Check whether the plug-in is loose and re-insert
it tightly
() Sensor quality problem replace the sensor
4 High current protection F6 electronic fan fault F7
() Check the condenser heat dissipation whether
the surface is dirty and blocked
() Check whether the terminal or plug-in of the
power line is loose
() Check if the plug-in of the fan is loose and plug it
in again
() Condenser fan failure replace the fan
