5 .Selection of Installation Position (Indoor / outdoor lens sequence needs adjustment)

Requirements for Installation Position The installation shall be operated at the place which is solid, unlikely subject to shock and able to bear the weight of machine. The outdoor unit shall be installed at the place which with good ventilation, and unlikely subject to rain or direct sunshine. Ensuring that the air conditioner can be easily accessed for maintenance and repair. Keep the indoor and outdoor units as close as possible. The connection pipe shall be short as it might be. To facilitate the air flow, keep adequate space around the indoor and outdoor unit, and avoid flammable or corrosive gas nearby. The drainage shall not affect the constructions of dwellers underneath or the user himself. The machine shall be kept 2m or more away from the electric appliances and heat source. Avoid TV set, sound box, computer and other deluxe home appliances below the indoor unit. The indoor unit shall be able to blow the cold and hot air evenly to everywhere of the room. According to the power supply mode (powered by indoor or outdoor unit) and the length of power cable, select the position which close to the power supply, in order to facilitate the connection of power line. Moreover, ensuring that it is not needed to extend the power cable and selecting a position beyond reach of children. Determination of Installation Position Select the final position of indoor and outdoor unit according to the requirements above (Mark properly if needed).

6 .Execution of Installation

Installation of Wall-mounted indoor unit Unpack the machine and take out the accessories, wall-mounting plate and remote controller. Mount the bundled batteries into the remote controller and observe for abnormality. Before installation, make sure to energize the indoor unit and test it by using the remote controller. Observe the fan and swing louver for their working conditions. If any abnormality occurs, adjust immediately and install again. Fix the wall-mounting plate according to the selected position of indoor unit and the route of the pipe.

Firstly, use a steel nail to fix the wall-mounting plate onto the wall. Level it with the level gauge and then fix tightly.

Note: When installing the models with additional functions (purification device), we shall take the position of this device into consideration for the distance to the ceiling.

Select the position of wall-cross hole according to the position of wall-mounting plate.

Selection of piping mode: Try not to choose the mode of right exit-pipe so as to ensure the orderliness and smoothness of the pipe.

1. Route the pipe directly along the right side of the machine body. 2. Route the pipe directly on the rear. When bending the pipe, please support the elbow with your right hand and then use your left hand to rotate slightly for 90° before stop. 3. Route the pipe along the left side. This step is the same as the above step. The only difference is that the bending angle is higher than that in the previous step, that is, it should be bent to 180°. Take care to rotate this angle slightly and slowly; Otherwise the pipe would be flattened easily . Then, drill a hole (shuld be a little larger than the outer diameter of the wall-cross tube so as to ensure the wall-cross rube can be inserted through). Caution: For easy drainage of the water out of the internal unit, the indoor unit shall be mounted slightly higher than the wall-cross hole. Meanwhile, the wall-cross hole must be inclined outward down.

Make sure to take dustproof measures when drilling holes with the impact drill. Hang the indoor unit onto the clamp of the wall-mounting plate. Move the body of indoor unit left and right, and check if it is fixed tight. When multiple indoor units are to be installed in one room (e.g. guest hall, meeting room, restaurant, etc.), full consideration should be made to the integral appearance and working performance. They should be installed on the same level (with the upper as the benchmark) and keep a certain distance, thus to ensure that the working performance of each indoor unit will not be affected. Installation of Outdoor Unit

1. To install the outdoor unit onto the wall, use the bit of fixed depth to drill holes according to the selected position, but take care to avoid the wall clearance. Firstly, mount an expansion bolt 10x100 (mm). Then, use the rope to move the support outdoors and make a simple fixing. Calibrate the level with level gauge and mark out the other positioning holes. Then, remove the support and use the impact drill with fixed depth bit to drill the other fixing holes of the support. Finally, fix the support onto the exterior wall. 6 pcs required for model 61 or lower, and 8 pcs required for the model over 61.

Note: The expansion tube of the expansion screw must be fully punched into the wall. 1. Move the outdoor unit out of the room and put it onto the support with care. Fix with 4 bolts O10mm. (Note: The installation people working on the 2nd floor or higher must wear safety belt. The outdoor unit must be tied securely with rope before it can be put outdoors. Take anti-fall measures to avoid accident. )

2. The outdoor unit is directly onto the ground (e.g. balcony, roof platform, outdoor ground of the 1st floor, and other platforms that can accommodate the outdoor unit adequately). According to the size of chassis mounting hole, select proper expansion screws to fix tightly. The height difference between indoor and outdoor unit shall not be higher than 5m; otherwise it might cause difficulty to oil return and affect the service performance.

Installation Requirements for Multiple Units

1. To install multiple units on the same wall or on the same direction of a building, all the machines on one floor should be installed on the same level (based on the level of machine leg), and the transverse spacing shall be kept at least 60cm or more, as long as the machine performance will not be affected.

2. If there are multiple units on different floors on the same wall or the same direction of the building, they should be preferably installed on the same vertical line (based on the left side of the body streamline). To avoid air return or mutual interference at the outlet, the longitudinal spacing shall be kept at least 65cm or more. Requirements for outdoor guardrail (optional): If the user is to install guardrail for the outdoor unit, the spacing to the machine body must be kept 0.5m or more.

Insert through Pipe Bundle the connection wire to the connection pipe and drainage pipe. (The connection wire may also be inserted through PVC pipe) To insert through the pipe, protective measures should be taken to prevent the expanded bell mouth from damage and prevent the sand from entering the connection pipe. Connect to Machine Take a connection pipe with expanded mouth, coat frozen oil evenly onto the connector of the 2-way / 3-way valve and the expanded mouth . Put the expanded mouth and connector on the same straight line and rotate the nut to its end with hands, and tighten it with spanner. Remove the end cover and clip of outdoor connection wire. Then, connect the wire to position according to color or mark indicated in the wiring diagram. When the exposed section is fully inserted, use the screw to press it tightly. Do not cut the round connector at the connection wire end into Y-shape. Fix the wire with clamp and then fix the end cover of the wire. Vacuumming After connecting the pipe between indoor and outdoor unit, it should be vacuumed with vacuum pump. Operate as follows:

Loosen the nut on low-pressure valve element and filling portal, connect the vacuum pump to the filling portal by hose with pin, and then start the vacuum pump. When the indicator gauge points to 15Pa, stop vacuumming and hold for approx. 30s. Pay attention to the vacuum level. If decreased, be sure to eliminate the leakage. Repeat the above procedures. When the vacuumming process is completed, close the vacuum valve and open the high-pressure valve element for 1/4 turn to fill the refrigerant to the low-pressure section. Remove the connection hose. Fully open the high-pressure and low-pressure valves . Tighten the nuts on the valves. Leakage Detection Use a sponge soaked with soap water or a leakage detector to check the connectors and access-valves on indoor and outdoor units. Keep testing for no less than 3 minutes at each position. When the leakage detection is completed, do wash away the residual soap water. (Notes: In summer, leakage detection should be done under stop state. In winter, it should be done under heating mode). )

Position Most Likely to Leak

Besides four connectors connecting outdoor pipes, nuts at high-pressure / low-pressure valve core and filling portal are most likely to leak but often neglected. Therefore, when installing the machine, make sure to fully open the valve core to dead position and tighten every nut and check for leakage. The connector with leakage problem should be reinstalled. Pipe Wrapping and Wall Hole Blocking Sort the pipeline in good order. Use pipe bender when bend the pipe with 90°. To avoid flattening or cracking the pipe without pipe bender, do bend it with a radius as large as possible.

3?when inlet and outlet temp. sensor of indoor evaporator appears malfunction for DC Inverter Multi-Split Air-Conditioner Unit,the current indoor unit will shut down and display the relevant malfunction code?

3.2 communication error protection

If the communication is abnormal for continuous 3min,the system will stop the compressor and display the relevant malfunction code?When the communication is normal and fault code disappears for 1 minute , the system will automatically start?

3.3 PG motor protection function

If the system checks the PG motor has not the feedback signal for continuous 20 seconds in the PG motor running,the PG motor will enter the running within fault;if the system checks the speed of PG motor is lower than 200rpm for continuous 60 seconds,thus the system considers PG motor faulty ,and then the total units stop running and report the relevant malfunction code?

The following is the setting motor speed during operation within fault:

(1) the system will break-over controlled silicon after zero passage 1mS in the high wind;

(2) the system will break-over controlled silicon after zero passage 2mS in the mid wind;

(3) the system will break-over controlled silicon after zero passage 2.5mS in the low wind;

(4) the system will break-over controlled silicon after zero passage 3mS in the slightly wind;

if the feedback signal returns to be normal during PG motor operation within fault,the PG motor still runs within fault,until the system starts again next time?

remark: there is not PG motor protection function in producing self-check?

VII?Reference of the fault code and detecting methods for inverter

Please note: this operation guidance is for maintenance reference only, it can be different from the units you order.

A?F1 (Communication fault) the possible reasons and detecting measures:

1. First, check whether the wires of the indoor and outdoor terminal boards are wrong connection or poor connection.

2. Check whether the alternating current of the outdoor PCB is normal, or whether the fuse is loosened or blew out.

(the input voltage of the outdoor terminal) (the input voltage of the Bridge rectifier)

(the fuse can be gotten through under the normal situation. Change the fuse if it is open circuit.)

3. Check whether the voltage of the DC PN is normal. The normal voltage should be around 300V.

(the output voltage of the Bridge rectifier) (the output voltage of the PN)

4. Check whether the input power cord or the output power cord is mistakenly connected in the controller board.

5. Check whether the communication voltage between the N and S is normal. Use the AC voltage gear to measure the voltage. If it changes from several volts to scores of volts, it means the communication voltage is normal.

6. Check whether the bridge rectifiers are damaged

(The forward resistance of every diode in the bridge rectifiers should be around 500?)

(remove one terminal when measuring the output resistance of the bridge rectifiers (the AC input resistance of the bridge rectifier should be infinite)

7. Check whether the electrolytic capacitor is convex or burned out.

8. Check whether the IGBT is damaged

;

9. Check whether the relative electronic components are burned out or loose weld by eyeballing.

10. Check whether the external environment exists the source of the strong electromagnetism, which may cause disturb.

11. If the above procedures cannot solve the problem, please change the outdoor whole set of the electric control boards.

B.F2(Room Temperature sensor fault) F3(Indoor coil exit temperature sensor fault,Indoor coil entry temperature sensor fault or Indoor coil mid point temperature sensor fault)

1. Measure the resistance of the temperature sensor and check it referring to the resistance table. Check if the resistance has a serious deviation to the table.

(the environment temperature is about 32 degrees centigrade)

2. Check whether the inserter or the wires of the sensor are damage by eyeballing.

3. Check whether the sensor's circuit in the electronic control board is loss weld or damaged.

4. If the above procedures cannot solve the problem, please change the indoor electric board.

C?F4: fault of PG fan motor

1? Check whether the contacted terminal of the fan motor is loose.

2? Check whether the startup winding and running winding of the fan motor is broken (open circuit or short circuit)

3? Check whether the fan motor or the blade of it is blocked.

4? Check whether the indoor PCB is faulty (no signal output of the fan motor)

D?F6 fault of the outdoor sensor

1?Measure the resistance of the sensor and check up with the temperature-resistance table, and see if there is a great departure with the resistance.

2?Check whether the contactor and the circuitry is well

3?Check whether there is loose weld or damage of the sensor circuit part, situation like rupture which the finger points at in the following picture:

4? If the above procedures cannot solve the problem, please change the indoor PCB.

E?FC fault of the outdoor drive and failure of the compressor startup

1?Drive module burns out, that is short circuit between P?U?V?W?N terminal.

(Normal forward resistance between P terminal and U,V,W,N terminal should be 380-450?)

(Normal voltage between U terminal and V,W terminal should be 170-270V)

2?Check whether the U,V,W terminals is contacted well

3?Check whether the compressor winding is burnt out.

(Normal resistance of the three windings should be the same and probably equal to 1?)

5?Check whether the compressor is blocked. If blocked, please try to beat the compressor with rubber stick slightly.

F?dI mode conflict or not allowed

We suggest you reset the running mode (cold or heat), and make sure all the indoor units are running in the same mode.

G? dF: defrost

1?Under the heat mode, it's a normal display of defrosting.

2?Under other mode except heat, if there is a dF code, perhaps the anti-jamming capacity of the inductance is too weak which leads to a misinformed faulty code. Please check whether there is a magnetic ring on the connecting pipe of the indoor and outdoor units.

H? P2:fault of the outdoor inverter module protection

1?Check whether the connection of the compressor is reliable. If not, please make it firmly enough.

2?Check whether the fixation between the IPM module and the radiator is firm.

3?Check whether the compressor is well. If not, please replace it.

4?Check whether the IPM module is normal. If not, please replace it.

I?P3 ac current input of the outdoor unit is too large

1?Check whether the ambient temperature exceeds the operation range of the air conditioner

2?Check whether the current detection circuit is abnormal. The electric control should be replaced if it is abnormal.

3?Check whether the outdoor fan motor is broken or not, following is the test method of ac outdoor motor:

4? If the above procedures cannot solve the problem, we suggest changing the inductance.

J? P4 discharge temperature of the outdoor compressor is too high, the outdoor ambient temperature is too high, temperature switch of compressor shell is breaking, the module is over temperature

1?Check whether the pressure is normal when the unit is running. If abnormal, should detect the leakage and welding, and then add refrigerant.

2? Check whether outdoor ambient temp. is too high or too low, when the temp. is more than -20 degree and less than 55 degree, it can disappear automatically.

3?Communicate interference. Earth wire and communicate wire can't put in one cable.

4?Check whether temp. switch of compressor is damage, it should be replace if it's damaged.

K? P7 dc generatrix voltage of outdoor unit is abnormal

1?Check whether the power supply voltage is out of rang from 150 to 270V

2.?Check the voltage detection circuit of the IPM base board is abnormal, if abnormal, the IPM base board or the electric control board should be replaced.

L? P8: gas leakage or fault of the selector valve

1?Check whether the high and low pressure valves have been opened. If not, please open the valves.

2?Check whether the indoor coil pipe temperature sensor is normal. If abnormal, the sensor should be replaced.

3?Check the system pressure is normal. If abnormal, should detect leakage repairing, welding and add the refrigerant

4?Check whether the coil resistance of the electric expansion is normal and the valve body is open completely.
