Be sure the installation area does not deteriorate with age. If the base collapses, the air conditioner could fall with it, causing property damage, product failure, and personal injury. 1.
There is risk of electric shock or fire. product. To avoid vibration of water leakage. Stop operation and disconnect the power during storm or hurricane. If possible, further secure the product before the hurricane arrives. There is risk of property damage, failure of product, or electric shock. Do not install the product where the noise or hot air from the outdoor unit could disturb the neighbors. It may cause disturbance for your neighbors.
Use a firm stool or ladder when cleaning or maintaining the product. Be careful and avoid personal injury. Replace the all batteries in the remote control with new ones of the same type. Do not mix old and new batteries or different types of batteries. There is risk of fire or explosion. Do not recharge or disassemble the batteries. Do not dispose of batteries in a fire.

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).

Note: When T1-Ts stays in the same temp. zone for 3 minutes, the compressor will run as the below rules: A~E: Increase the frequency to the higher level until reaching F8. F: Keep the current frequency. G: Decrease the frequency to the lower level until reaching F1. H: Run at F1 for 1h. (if T1-Ts<-2℃, the compressor will stop) Meanwhile, the compressor running frequency is limited by the current.
For other models, when the compressor is running, the indoor fan will run at setting fan speed. When the setting temp. is reached, the 34 33 indoor fan will run at lowest fan speed. 28 27 Auto fan running rules: For 9000 BTU, 12000 BTU and 18000 BTU, 20 SEER Cool Only and Heat Pump models: Off Fmax=F2 25 24 Fmax=F3 22 21 Fmax=F4 19 18 Fmax=F5 17 16 Fmax=F6 15 14 Fmax=F7 12 11 Fmax=F8 6 5 Fmax=F9 T1-Ts 6.0 5.0 4.0 2.5 1.0 H a b c d e (H-L)*0.75+L (H-L)*0.5+L (H-L)*0.

and cooling, the compressor will keep stopping for 15 minutes and then choose mode according to T1-Ts. If the setting temperature is modified, the machine will choose running function again. 8.4.6.3 Operation rules: Forced cooling mode: The compressor runs at F2 frequency and indoor fan runs as breeze. After running for 30 minutes. the machine will turn to auto mode as 24℃ setting temperature. Forced auto mode: The action of forced auto mode is the same as normal auto mode with 24℃ setting temperature. 8.
temperature stops rising and indoor fan is fixed as low speed. (Warm-Start function has the priority) 8.4.8.3 Timer setting is available 8.4.8.4 When user uses timer off function in sleep mode (or sleep function in timer off mode), if the timing is less than 7 hours, sleep function will be cancelled when reaching the setting time. If the timing is more than 7 hours, the machine will not stop until reaching the set time in sleep mode.
Press the “silence” button on remote controller to initiate SILENCE function. When the Silence function is activated, the compressor running frequency will keep lower than F2 and the indoor unit will bring faint breeze, which will reduce the noise to the lowest level and create a quiet and comfortable room for you.

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.
Remark: Use a multimeter to test the DC voltage between L2 (or N for 115V) port and S port of outdoor unit. The red pin of multimeter connects with L2 (or N for 115V) port while the black pin is for S port. When AC is normal 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.
9.3.3 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.
9.3.4 Fan speed has been out of control diagnosis and solution (E3/E7/F5) Error Code E3 Malfunction decision When indoor fan speed keeps too low (300RPM) for certain time, conditions the unit will stop and the LED will display the failure.
Index 1: 1.Indoor or Outdoor DC Fan Motor (control chip is in fan motor) Measure the resistance value of each winding by using the tester. If any resistance value is zero, the fan motor must has problems and need to be replaced. Index2: 1:Indoor or Outdoor DC Fan Motor(control chip is in fan motor) Power on and when the unit is in standby, measure the voltage of pin1-pin3, pin4-pin3 in fan motor connector.
9.3.5 Open circuit or short circuit of temperature sensor diagnosis and solution (E5) Error Code E5 Malfunction decision If the sampling voltage is lower than 0.06V or higher than 4.94 V, conditions the LED will display the failure.
9.3.6 IPM malfunction or IGBT over-strong current protection diagnosis and solution (P0) Error Code P0 Malfunction decision When the voltage signal that IPM send to compressor drive chip conditions is abnormal, the display LED will show “P0” and AC will turn off.
