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

Code Description Troubleshooting
E0 Inlet temp sensor fault Check sensor connector
E1 Outlet temp sensor fault Check sensor connector
E2 Low Voltage Check battery or harness
E3 High Voltage Check battery or power
E4 Pressure (system leakage) Check R134a leakage
F0 Disconnected/Blocked compressor Check cooling fan working or not / R134a overcharge
F1 Compressor driver overheat Check cooling fan working or not / ambient>55ºC
F2 Compressor driver wire low-voltage Check harness false connection or not
F3 Compressor driver over voltage Check wire false connection
F4 Compressor driver phase absence Check wire false connection
F5 Driver output overload Check wire false connection
F6 Driver output over current Check cooling fan working or not / ambient>55ºC
F7 Cooling fan fault Check cooling fan working
Ways to deal with the above code: Turn off the power and turn on the machine in 5 minutes If the fault is not
solved please refer to the maintenance manual or contact the local dealer

Maintenance
In order to ensure the normal operation of the air
conditioner please pay attention to the
routine maintenance:
() When idle for a long time please remove the positive
and negative power lines at the battery end and pay
attention to the sealing and to avoid negative connection
direct to ground so as to avoid battery damage caused by
long-term electrification (the power line must be connected
to the battery and it is strictly forbidden to connect negative
direct to ground or connect the generator)
() The air conditioner needs to be maintained every 3
months (cleaning evaporator and condenser checking
internal and external circuits); the maintenance cycle
should be shortened appropriately in special working
conditions such as dusty and high temperature
environment Refer to table 7 of the maintenance manual
for product maintenance
() It is not recommended to install generators solar
energy and other external charging equipment
Discaimer
() We provide installation videos and installation
Instruction users must install strictly in accordance with
the video and instructions If the user fails to install in
accordance with the installation video and instructions
provided human failure or damage and other accidents
occur the user shall bear the responsibility the
maintenance and material costs caused by the user shall
be paid separately and our company will not bear
any responsibility
() The user must pay attention to safety issues during
the installation process in case personal safety issues
occur the user must bear the responsibility
() If the user changes the air conditioning privately or
the replacement of parts and components that are not
the original happens the user shall bear the
responsibility of the caused damage to the air
equipment and personal safety issues our company will
not bear any responsibility
