6.4 Installation for the first time 5) Operate the vacuum pump to evacuate. 6) Make evacuation for 30 minutes and check whether the compound meter indicates -0.1Mpa(14.5Psi). If the meter does not indicate -0.1Mpa(14.5Psi) after pumping 30 minutes, it should be pumped 20 minutes more. If the pressure can’t achieve -0.1Mpa(14.5Psi) after pumping 50 minutes, please check if there are some leakage points. Fully close the Low side valve of the manifold and stop the vacuum pump.
2). Purge the air from the charge hose. Open the valve at the bottom of the cylinder and press the check valve on the charge set to purge the air (be careful of the liquid refrigerant). 3) Put the charging cylinder onto the electronic scale and record the weight. 4) Operate the air conditioner at the cooling mode. 5) Open the valves (Low side) on the charging manifold set and charge the system with liquid refrigerant. 6).
manifold hose with the push pin to the 3-way valve's gas service port. 3). Air purge of the charge hose. Open the Low side valve of the manifold slightly to purge air from the charge hose for 5 seconds and then close it quickly. 4). Set the 2-way valve to the close position. 5). Operate the air conditioner at the cooling cycle and stop it when the gauge indicates 0.1Mpa(14.5Psi). 6). Set the 3-way valve to the closed position immediately Do this quickly so that the gauge ends up indicating 0.3Mpa(43.
2. Refrigerant charging Procedure: 1). Connect the charge hose to the charging cylinder, open the 2-way valve and the 3-way valve Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder. If the refrigerant is R410A, make the cylinder upside down to ensure liquid charge. 2).

8.3 Main Protection recently or if T4＜3℃ and compressor has stopped for over 3 hours, the compressor heating circuit will activate. Preheating mode: A weak current flow through the coil of compressor through the wiring terminal of the compressor, then the compressor is kept warm without operating. Preheating release condition: If T4＞5℃ or the compressor starts running, the preheating function will stop. 8.3.
8.4 Operation Modes and Functions Fmax: The maximum operation frequency of compressor. F1~F8: The detailed value of the compressor operation frequency. If users switch on the unit by remote controller, the compressor will run at the Fmax frequency for 7 minutes according to the outdoor ambient temp. During the 7 minutes, the frequency limitation is active. 7 minutes later, the compressor running frequency will be controlled as below: 8.4.1 Fan only mode (1) Outdoor fan and compressor stop.

The units run with T3＜3℃ for 80 minutes and T3 stays lower than TCDI+2℃ for more than 3 minutes. ----T4＜0℃, If the 1st condition and 2nd condition items are satisfied, then the program judges if T2 has decreased more than 5℃. When T2 has decreased more than 5℃, system will enter the defrost mode.
The louver operates same as in relevant mode. If the machine switches mode between heating and cooling, the compressor will stop for 15 minutes and then choose mode according to T1-Ts. If the setting temperature is modified, the machine will re-determine the running function again. For 18k, 24k models: Frequency F2 Frequency F8 Compressor 4-way valve Outdoor fan Indoor fan on off on off 8.4.5 Drying mode 8.4.5.1 Indoor fan speed is fixed at breeze speed and can’t be changed.
8.4.6.2 In forced operation mode, all general protections and remote control is available. 8.4.6.3 Operation rules: Forced cooling mode: The compressor runs at F2 frequency and indoor fan runs as breeze speed. After running for 30 minutes. the machine will turn to auto mode with 24℃ setting temperature. Forced auto mode: The action of forced auto mode is the same as normal auto mode with 24℃ setting temperature.
9. Troubleshooting Safety Electricity power is still kept in capacitors even the power supply is shut off. Do not forget to discharge the electricity power in capacitor. Electrolytic Capacitors (HIGH VOLTAGE! CAUTION!) For other models, please connect discharge resistance (approx.100Ω 40W) or soldering iron (plug) between +, terminals of the electrolytic capacitor on the contrary side of the outdoor PCB. Note: The picture above is only for reference. The plug of your side may be different.

9.3 Diagnosis and Solution 9.3.1 EEPROM parameter error diagnosis and solution(E0/F4) Error Code E0/F4 Malfunction decision Indoor or outdoor PCB main chip does not receive feedback conditions from EEPROM chip. Supposed causes ● Installation mistake ● PCB faulty Trouble shooting: Shut off the power supply and turn it on 5 seconds later. Is it still displaying the error code ? Yes If the EEPROM chip is welded on main PCB, replace the main PCB directly.
9.3.2 Indoor / outdoor unit’s communication diagnosis and solution(E1) Error Code E1 Malfunction decision Indoor unit does not receive the feedback from outdoor unit during conditions 110 seconds and this condition happens four times continuously. Supposed causes ● Wiring mistake ● Indoor or outdoor PCB faulty Trouble shooting: Power off, then turn on the unit 5 seconds later(reconnect the power wire).
Remark: Use a multimeter to test the DC voltage between L2 (or N on 115 V Models) port and S port of outdoor unit. The red pin of multimeter connects with L2 (or N on 115 V Models) port while the black pin is for S port. When AC is normally running, the voltage will move alternately between -50V to 50V. If the outdoor unit has malfunction, the voltage will move alternately with positive value. While if the indoor unit has malfunction, the voltage will be a certain value.
9.4.3 Zero crossing detection error diagnosis and solution(E2) Error Code E2 Malfunction decision When PCB does not receive zero crossing signal feedback for 4 conditions minutes or the zero crossing signal time interval is abnormal.
9.4.4 Fan speed has been out of control diagnosis and solution(E3) Error Code E3 Malfunction decision When indoor fan speed stays too low (<300RPM) for certain time, conditions the unit will stop and the LED will display the failure.
