When removing the unit to the other place, please firstly contact with the authorized Maintenance Center in the local area.
Installation Safety Requirements For Electric Appliances 1. The power supply should be used the rated voltage and AC exclusive circuit, the power cable diameter should be satisfied. 2. Don't drag the power cable emphatically. 3. It should be reliably earthed, and it should be connected to the special earth device, the installation work should be operated by the professional.
Installation Install the rear panel 1.Always mount the rear panel horizontally. Due to the water tray of indoor unit has been adopted the both-way drainage design, the outlet of water tray should be adjusted slightly down when installing, that is taking the outlet of the water tray as the center of a circle, the included angle between the evaporator and level should be 0 or more, that is good for condensing water drainage. Wall 2.Fix the rear panel on the wall with screws.
Installation NOTE: When connecting the electric wire if the wire length is not enough, please contact with the authorized service shop to buy a exclusive electric wire that is long enough and the joint on the wire are not allowed. ● The electric wiring must be correctly connected, wrong connection may cause spare parts malfunction. Tighten the terminal screw in order to prevent loose. After tighten the screw, slight pull the wire and confirm whether is it firm or not.
Installation Electric wiring 1. Disassemble the handle on the outdoor unit right side plate. 2.Take off cord anchorage. Connect and fix power connect cord (for cooling and heating unit,connect and fix power connect cord and signal control wire)to terminal block. 1 %8 %. %1 <(*1 3.Fix the power connection cable with cord anchorage, (for cooling and heating unit, use the cord anchorage to fix the power connection cable and the signal control wire). Handle 4. Ensure wire has been fixed well. 5.
Troubleshooting Guide Troubleshooting Guide Note: When replacing the controller, make sure insert the wire jumper into the new controller, otherwise the unit display C5 The breaker trips at once when it Measure insulation resistance to ground to see if there is any leakage. is set to "ON". Trip of breaker or blow The circuit or the part of the air conditioner has of fuse malfunction. They heat and break the insulation The breaker trips in few minutes and lead to short circuit or creepage.

Troubleshooting Guide The indoor fan motor is burned or breaks or has the heat protector malfunction. The fan does not run when it is set to supply air. In the cooling and heating mode, the compressor runs, but the outdoor fan does not run. When cooling or heating, outdoor fanruns,compressor doesn't run. The compressor is too hot and leads to the action of the protector. Replace the fan motor or the defective part.
!"#$%&'("")*+,-.#*/&- Controller malfunction (IC2003 broken, creepage of parallel capacitor of relay loop, Change controller relay is broken etc.) In cool, heat mode,the outdoor unit and compressor will not run. Wire loose or wrong connection Correctly wire according to the drawing Improper setting of temperature Adjust setting temp. Drainage pipe blocked or broken Change drainage pipe Wrap of refrigerant pipe joint is not close Re-wrap and make it tight. Water leakage enough.

Troubleshooting Guide (5) Out of step diagnosis for the compressor (AP1 hereinafter refers to the control board of the outdoor unit) Mainly detect: Whether the unit voltage is too high? Whether the work voltage is too low? Out of step occurs once the unit is powered on.
Troubleshooting Guide (6)Overload and air exhaust malfunction detect (following AP1 for outdoor unit control board) Mainly detect: Wether the electronic expansion valve is connected well or not? Is electronic expansion valve damaged? Is refrigerant leaked? 20 minutes after the complete unit is powered off Is the terminal FA for the electronic expansion valve connected correctly? Resistances between the first four pins close to the terminal hole and the fifth pin are almost the same, less than 100 ohm.
Troubleshooting Guide ˄7˅Power factor correction (PFC) fault (a fault of outdoor unit) (AP1 hereinafter refers to the control board of the outdoor unit) Mainly detect: Check if the reactor (L) of the outdoor unit and the PFC capacitor are broken The failure diagnosis process is as follows: Start Check wiring of the reactor (L) of the outdoor unit and the PFC capacitor Whether there is any damage or short-circuit? Y Replace it as per the wiring diagram and reconnect the wires If the fault is eliminated
