1. The installation step of the indoor machine:

1. After selecting the installation position, fix the installation board.

Take off the installation board on the back of the indoor machine and place it on the pre -selected installation location. When the installation board is placed, it should be kept horizontally with a horizontal or heavy hammer, and the distance between the roof and the left and right walls should be left to facilitate the circulation of the air. Use a pencil or screwdriver to make a fixed -hole position mark on the wall.

2. Drill the fixing hole with an electric hammer determined by the fixed holes determined by the installation board.

Insert the plastic bloating tube in the hole, and fix the installation board on the wall with a self -attack screw. There must be no less than 4 fixed holes in order to better load and fixed indoor machines. In the end, the level or heavy hammer must be used to confirm whether the installation board is horizontal again. If it is not horizontal, it must be adjusted until the level.

3. Drill the wall hole with an electric hammer or rhinestone.

When drilling, try to avoid cables, equipped with other objects or excessive texture. The inside of the hole should be higher than the outer 0.5 -1cm for drainage. The wall holes from the side of the indoor machine should be slightly lower than the lower side of the indoor machine.

4. After the wall holes are drilled, put in the wall protection tube.


The length of the protective tube should be equal or slightly longer than the thickness of the wall. Installing the wall protection tube is to avoid the connection wires of the air conditioner to contact the metal in the wall, or to prevent mice from entering the room from the hollow wall.

5. Install the connection pipe.


Adjust the direction and location of the indoor machine outlets according to the position of the installation board and the wall hole, and then connect the indoor machine to lead the tube and connect the pipe. When the connection pipe is connected, wipe the cone surface of the joints and the bell mouth of the joint first, and apply a small amount of freezing oil in the trumpet mouth and the connector thread. The cone surface of a connector is aligned with the bell mouth of the other connecting tube. First, tighten the nut nuts with your hand, and then tighten with two activity wrenchs at the same time. Remember not to twist the nut with only one wrench, which will cause cracking at the connector and joint welding.

6. Use thermal insulation materials and bandaging bandaging pipes, power cords and signal cables.

When bandaging, the power cord and signal line are on the upper side, the connecting pipe is in the middle, and the drain pipe is on the lower side. When a drainage pipe is needed, the extended part of the drainage pipe should be covered outside the original drainage pipe to avoid leakage. The drainage pipe interface should be sealed with glue. Do not bandage the connecting pipes when bandaging to prepare the leak.

7. Hanging indoor machine.


Put the bandaged connecting pipes and wires into the wall holes. Be careful not to touch the speaker mouth of the connector, and do not let the sediment of the wall enter the connector. Hang the indoor machine on the installation board and check whether the suspension is firm. Finally, adjust the indoor machine level with horizontal or heavy hammer.


Second, the installation step of outdoor machine:

1. Fix the installation bracket with expansion bolts.


When the wall is thinner or inadequate, it should be fixed with a long bolt through the wall. The bolt should be used to prevent loose pads to prevent the bolt loosen or fall. The fixed bolt of the installation bracket must not be less than 6, and the diameter must not be less than 10mm. The fixed installation bracket should bear the weight of 4 times the total weight of the person and the machine and maintain the level.

2. Fix the bolts with a diameter of 10mm in diameter of 10mm on the bracket.


The bolts should be worn from top to bottom, and anti -pine pads are added. After fixing, check whether the outdoor unit is level. If the outdoor unit is installed at a place higher than the indoor machine, the high -voltage connection pipe and the low -voltage connector should set the liquid ring and the oil storage ring, respectively, and the indoor and unit high difference should be less than 5m.

3. Connect the power cord and signal line.

Open the wiring box of the outdoor unit, and connect the power cord and signal line according to the number of pairing in the indoor machine wiring box and the outdoor wire wiring box. When the connection line is extended, the original line should not be cut off, and a new connection line that meets the standards should be replaced. The inverter air conditioner must use the signal line that comes with the machine itself, and it must not be extended or replaced at will.


4. Connect the pipe and use the refrigerant that comes with the outdoor unit to eliminate the air from the indoor machine and the connecting pipe.

Refer to the schematic diagram below, tighten the connecting nut at the A, and then loosen the connecting nut at the B at the B, so that it is leaked. Open the two -way truncation valve with the inner hexagon wrench for about 5 seconds, fill the indoor and connecting tube into the refrigerant, and squeeze the air from the B -joint nut. Then turn off the cut -off valve and quickly tighten the joint nut at B.


Environmental refrigerant must be vacuum. The A and B nut are tightened, and the valve is not opened. Use the vacuum pump to pump from the fluorine port of the three -way valve to be vacuum, and pump the air in the copper tube clean. Normally draw for about 30 minutes.

5. Open the two interception valves.

Note that if the cut -off valve is not enabled, it will cause the air -conditioner system to block and affect the cooling and heat -making effect.

6. Use soapy water or leak detector to detect interfaces everywhere.

The stay time for not less than 3 minutes during leakage.

In summer, you must leak in the state of stop; you must leak in the heating state in winter. After ensuring no leakage, open the panel and inject some water into the evaporator to observe whether the drainage is smooth.

7. Confirm whether the power supply is good and whether there is any error in the wiring.

During the trial operation, carefully check the effects of ventilation, refrigeration and heating by the product instruction manual. In general, when the indoor temperature is above 20 ° C, the cooling mode can be turned on; when the indoor temperature is lower than 15 ° C (below 20 ° C) in winter , Can open the forced refrigeration mode, at least 30 minutes of trial running.

During the trial operation, the indoor machine is measured by the temperature meter to measure the temperature difference between the indoor machine. If the temperature difference is above 8 ° C during the cooling, the temperature difference during heating is above 15 ° C. It is generally believed that the installation is successful.


8. Complete.

The connection tube is re -shaped. The radius of the corner of the connection tube is greater than 10cm. When the bending pipe is bent, the connection tube shall not be flat and flattened. After the plastic surgery, the connecting pipe is fixed with a tube card every 1.5m to prevent noise during the work of the machine. After the installation is over, seal the wall holes with a mud dense to prevent air foreign bodies from entering the room.
