Is the Midea air conditioner you bought still installed within two years after it was removed?

Look at the installation card! Or just find someone to install it, it's not expensive, about 50 yuan, but each area has a different charge.

Midea air conditioner outdoor unit installation:

1.According to the position of the outdoor unit and the hole position on the mounting frame, the expansion bolt holes are punched, and the number and specification of the holes must meet the requirements of the installation manual;

2.To fix the mounting frame of the outdoor unit, the number and specification of expansion bolts must meet the requirements of the installation manual;

3.The outdoor unit is in place and penetrates the bolt, and the bolt is tightened after calibration, and the height difference of the outdoor unit per meter length cannot exceed 5mm;

4.Unscrew the interface cap on the valve of the outdoor unit, connect the refrigerant connecting pipe, be sure to use two wrenches when connecting, use a movable wrench to fix the valve, and use a torque wrench to tighten the joint nut.

5.Connect the refrigerant connection pipe to the pipe joint of the indoor unit, be sure to use two wrenches to fix the joint bolts with a movable wrench, and use a torque wrench to tighten the joint nut. If the condensate drain pipe is not long enough, connect it to the pipe that comes with the machine;

6.Remove the control box cover of the outdoor unit, connect the cables to the corresponding terminals of the terminal board according to the number and color, and then put on the control box cover;

Debugging Wiring Diagram:

After the power is turned on, press the refrigeration and heating to see if the air conditioner can cool and heat. I hope the leopard can help you.

Air conditioners are generally only installed for the first time, and they will definitely not be installed for free after being removed, so they can only find a third party to install them at their own expense.

Appliances are only installed once, not unlimited package installation, as long as they are installed once, whether it is 2 days or 2 years, they are no longer installed for free.

Yes, the cost is about 150.

1.**Refrigerant The refrigerant in the air conditioner must be collected into the outdoor unit. Start the air witherer before dismantling, you can set the refrigeration state, wait for the compressor to run for 5 10 minutes, after the refrigeration state is normal, unscrew the cap on the interface between the liquid pipe and the gas pipe of the external machine, close the cut-off valve of the high-pressure pipe (fine), and condense the surface of the pipe after l minutes, immediately close the low-pressure pipe (thick) cut-off valve, and quickly shut down the machine, unplug the power plug, tighten the safety cap with a wrench, and the refrigerant work is completed so far.

You can also use the forced start button on the indoor unit to turn on the machine, and observe whether there are other faults in the indoor and outdoor units. Avoid the trouble caused by the relocation of the air conditioner.

2.After disassembling the indoor unit refrigerant**, the indoor unit can be disassembled. Use a wrench to unscrew the connecting lock nut of the indoor unit, and use the prepared sealing sodium to unscrew the silk pattern of the connecting joint of the indoor unit to prevent the joint from being damaged during handling; Then use the cross to remove the control line.

At the same time, it should be marked to avoid the wrong connection during installation. If the signal cable or power cable is connected incorrectly, the external unit will not work, or the machine will not be controlled. The internal hanging plate is generally fixed firmly, and it is difficult to unload; After unloading, remove the hanging board, put it on the flat cement floor, and then gently pat it flat and correct.

3.After unscrewing the connecting lock nut of the external machine, the prepared sealing sodium should be used to unscrew the silk pattern of the connecting joint of the external machine. Then use a wrench to loosen the fixing screws on the foot of the outer machine.

When putting down the outdoor unit after disassembly, it is best to hang it with a rope, and pay attention to balance while unloading, avoid vibration and bumps, and pay attention to safety. Slowly straighten the pipe of the outdoor air conditioner and seal the four ports of the connecting pipe with the four plugs prepared to prevent dust and moisture from entering the air. The plug is good, and finally tied with a plastic bag and plated for easy handling.

4.Installation After determining the position of the internal and external machine, immediately install the internal machine hanging plate, and after the external machine and the internal machine hanging plate are installed firmly, then straighten the connecting pipe to see if the pipeline is bent or deflated; Next, check the flare at both ends, if there is a crack, it should be re-flared, otherwise fluorine will leak. Finally, check the control line, and after making sure that the pipeline, control line, and outlet pipe are in good condition, tie them together and seal the connecting nozzle.

When crossing the wall, two people should cooperate inside and outside the wall to slowly penetrate out to avoid strain; Connect the pipeline with the internal and external units, and connect the control line. Next, remove the air from the ducts and the internal unit.

Here's how:

1) Tighten the connected external coupling (fine) and loosen the stem of the shut-off valve about 1 turn with a special wrench.

2) Hear the squeak of the (coarse) joint of the external machine, and tighten the (coarse) joint with a sheet metal hand for about 30 seconds.

4) Completely loosen the stem of the shut-off valve on the (thin) tube. The space-time witherer empties out.

5) Finally, use detergent for leak detection, carefully observe whether there are bubbles coming out of each joint, and after verifying that the system is indeed leaking, tighten the valve safety cap, and then start the test operation.

6) If the refrigeration effect of the air conditioner is not good during normal operation, and the temperature of the air outlet of the indoor unit does not meet the requirements, consider supplementing Freon refrigerant.

7) The refrigerant charge is completed, and the relocation work is completed.

It is free to install when you buy it, but you will be charged for disassembling and assembling it in the future, and it is generally about 50 yuan for disassembly and assembly.

Of course, you need money, you have to pay the workers. You have to ask the workers to dismantle it separately outside. There is no cost, the cost is manpower. It takes time and physical energy. Such high temperatures, high altitudes, outdoors. Specifically, it's all this.

Dismantling the air conditioner is not to repair the air conditioner, it still costs money, ** in the range of 150-200.

If you still have questions, you are welcome to ask questions to the company in the United States; I wish you a smooth work and a happy life!

If you want money, this is not a warranty.

It's extra business, and it's definitely going to cost you.

Summary. Hello dear<>

If the air conditioner is not used for a long time after disassembly, there will be the following problems when installing it again:1Freon leaks:

When disassembling the air conditioner, it may cause freon leakage, which will reduce the cooling efficiency and energy efficiency ratio of the air conditioner. If the leak is severe, the air conditioner needs to be repaired. 2.

Scale blockage: If not used for a long time, the scale inside the air conditioner may block the pipes and affect the cooling effect of the air conditioner. Therefore, it is advisable to clean the air conditioner before reinstalling it.

3.Damaged air tightness: When removing and reinstalling an air conditioner, components such as pipe joints and refrigerant circulation systems can be damaged, resulting in air leakage.

Dear, the following are related developments, I hope it will help you <>< training

In short, more detailed cleaning and inspection are required before installation, so as to ensure that the air conditioner can work normally and efficiently. It is recommended to find a professional technician for installation and inspection. <>

The inverter air conditioner is not good after being removed and then installed, the refrigeration is not cool, and it is necessary to check whether the refrigerant is leaking, and then it is necessary to vacuum, and the steps of vacuuming are as follows:

If there is still a refrigerant in the outdoor unit, after installing the indoor and outdoor units, the air can be exhausted after connecting the copper pipe.

1. Unscrew the high-pressure valve a little bit, hear the sound of airflow, and then press down the liquid filling port on the low-pressure valve for 7 to 10 seconds (depending on the length of the air conditioning connecting pipe);

2. If you are not sure, in principle, you would rather drain for a few more seconds than less, because the residual air in the pipeline will affect the normal operation of the air conditioner, and the high and low pressure valves will be opened after the air is discharged.

3. The above is the exhaust method without vacuum pump, if there is a vacuum seal, the vacuum pump can be connected to the liquid filling port to directly extract the air in the air conditioning pipeline, and the vacuum will open the high hail and low pressure valves.

It is estimated that the refrigerant inside will leak during the disassembly and assembly process, and the refrigeration effect will be bad if the refrigerant is insufficient.

Air conditioners are semi-finished products, and the installation accounts for half of the effect. Find a master to see if there is no refrigerant.

The refrigerant is not enough, and it needs to be added to cool properly.
