Notes

1. Nominal cooling capacities are based on the following conditions:
   Indoor temp: 27°CDB, 19°CWB; Outdoor temp: 35°CDB; Equivalent ref. piping: 7.5m (horizontal)
2. Nominal heating capacities are based on the following conditions:
   Indoor temp: 20°CDB; Outdoor temp: 7°CDB, 6°CWB; Equivalent ref. piping: 7.5m (horizontal)
3. Actual noise levels may differ, depending on the room structure, etc, since these noise values are from an anechoic room.

Troubleshooting

Fault Code Table

E0: Indoor unit and outdoor unit communication failure Solution:

1. Check the communication cable between the indoor unit and the outdoor unit, if it is a short connection or broken;
2. Check whether the communication cable is connected corrected or not, if not, correct it;
3. If the cable and connection are both correct, check the connected lines from the communication terminal to the main board are corrected or not, if not, correct it
4. If all the above steps are done, still not solved change the indoor or outdoor main board

E1: Outdoor unit failure

• Check the details of the failure at the outdoor unit.

E2: Indoor ambient temp. sensor fault (T1 sensor) Solution:

1. Check the T1 sensor connection is loosened or not, and inset it firmly, if not solved, go to next step;
2. Take out the sensor, and measure the resistance of the sensor, it is about 5KΩ at 25℃, if not, replace it; if resistance normally, change the indoor main board.

E3: Indoor evaporator pipe temperature sensor (T2) failure Solution:

1. Check the T2 sensor connection is loosened or not, and inset it firmly, if not solved, go to next step;
2. Take out the sensor, and measure the resistance of the sensor, it is about 5KΩ at 25℃, if not, replace it; if the resistance is normal, change the indoor main board

E5: Condenser pipe temperature sensor (T3) failure Solution:

1. Check the T3 sensor connection is loosened or not, and inset it firmly, if not solved, go to next step;
2. Take out the sensor, and measure the resistance of the sensor, it is about 5KΩ at 25℃, if not, replace it; if the resistance is normal, change the main board

F2: Outdoor unit protection

• Solution:
• Follow the F3/F4/F8/F9.

F3: High pressure protection
Solution:

1. If the unit does not have a high-pressure switch, change the outdoor main board; if it has, go to next step
2. Take out the high-pressure switch, and measure its resistance, it is about 0Ω, if not, replace it; otherwise, go to next step;
3. Short-connect the high-pressure switch port on the outdoor board, if it still shows P1, replace the outdoor main board; otherwise, go tothe  next step;
4. Connect the pressure gauge to test the high pressure, if it is really too high, may be caused by too much refrigerant or other gas getting inside the system

F4: Low pressure protection
Solution:

1. If the unit does not have a low-pressure switch, change the outdoor main board; if it has, go to the next step
2. Take out the low-pressure switch, measure its resistance, and confirm whether it is about 0Ω, if not, replace it; otherwise, go to the next step;
3. Short-connect the low-pressure switch port on the outdoor board, if it still shows P2, replace the outdoor main board; otherwise, go to the next step;
4. Connect the pressure gauge to test the low pressure, if it is really too low, may be caused by a lack of refrigerant or leakage in the refrigerant system

F5: Water fulfilled protection (Alarm of condensing water overflow)
Solution:

1. If the unit does not have a water drainage pump:
   • a) Check whether the water level switch short short-connected or not, if not, short-connect it, if it is still not solved, change the main board
2. If the unit has a water drainage pump:
   • a)Check the water level switch if it is connected well, inset it firmly; then check if the switch is blocked or not, if it is blocked, replace it, otherwise go to the next step
   • b) Check the connection between the pump and the main board if it is 220-240V, if it is, change the water pump; if not, change the indoor main board

F7:Ourdoor overcurrent protection
Solution:

1. Check the dial switches is setting corrected or not according to the wiring diagram, if not, set it corrected; if correct, go to the next step
2. Check the condenser whether it is in good ventilation, if not, remove the blockage; otherwise, go to the next step.
3. Measure the current with a multimeter, and check the current via the unit check data also, compare these two data, if they are quite different, change the outdoor main board;
4. If all the above steps are done normally, it may cause the damaged compressor or refrigerant system blocked or dirty or other gas to get inside the system

F8: Outdoor unit exhaust temperature over-high protection
Solution:

1. Check whether the T5 sensor connection is loosened or not, and  inset it firmly, if not solved, go to next step;
2. Take out the exhaust sensor (T5) from the main board, and measure its resistance, it is about 50KΩ at 25℃, if not, change the sensor; if it is, go to the next step
3. Remove the sensor from the compressor, if it is still not solved, change the main board
4. If all the above steps are done normally, it may be caused lack of refrigerant or damaged compressor or refrigerant system being blocked or dirty or other gas get inside the system.

F9: Three-phase electricity power phase sequence failure
Solution:

1. Check whether the 3-phase power connection lines are connected well or not
2. Using the meter to measure the voltage (L1&N, L2&N, L3&N), all of them should be 220V, if not, correct the power supply, otherwise go to next step;
3. If the power supply is corrected, change the main board

P6: EEPROM failure

• Change the indoor mainboard
