How to disassemble the air conditioning method steps to see

How to disassemble the air conditioner when moving? This generally professional moving company has dedicated people in charge, but what should we do if we dismantle it ourselves? Below I will explain to you How to disassemble an air conditioner. The method is suitable for all kinds of air conditioners, and the disassembly and reassembly of air conditioners (universal method).

How to disassemble the air conditioner – steps/methods

Recycling refrigerant The refrigerant in the air conditioner must be collected into the outdoor unit. Before disassembling the machine, start the air conditioner and set the refrigeration status. Wait for the compressor to run for 5-10 minutes. After the refrigeration status is normal, unscrew the protective cap on the interface between the liquid pipe and the gas pipe of the external machine and close the high-pressure pipe (thin). After 1 minute, dew will form on the surface of the pipe. Immediately close the low-pressure pipe (coarse) stop valve. At the same time, quickly shut down the machine, unplug the power plug, and tighten the safety cap with a wrench. At this point, the refrigerant recovery work is completed. You can also use the forced start button on the indoor unit to turn it on, and at the same time observe whether there are other faults in the indoor and outdoor units. Avoid trouble caused by moving the air conditioner.

Disassembly of the indoor unit After the refrigerant is recovered, the indoor unit can be disassembled. Use a wrench to unscrew the indoor unit connection lock nut, and use the prepared sealing sodium to tighten the threads that protect the indoor unit connection joints to prevent the joint threads from being damaged during transportation; then use a cross lift to remove the control wires. At the same time, markings should be made to avoid incorrect connections during installation. If the signal wire or power wire is connected incorrectly, the outdoor unit may not operate or the machine may be out of control. The hanging plate of the indoor unit is generally fixed relatively firmly and is difficult to remove. After unloading, remove the hanging plate, place it on a flat cement floor, then gently tap it flat and correct it. After unscrewing the connecting lock nut of the outdoor unit, use the prepared sealing sodium screw. It is good to protect the threads of the connector connecting the external machine. Then use a wrench to loosen the fixing screws of the outer unit feet. When putting down the outdoor unit after disassembly, it is best to hang it with a rope. When putting it down, pay attention to balance, avoid vibration and bumps, and pay attention to safety. The connecting pipe of the outdoor air conditioner should be slowly opened, and the four ports of the connecting pipe should be sealed with the four prepared plugs to prevent dust and moisture in the air from entering. Plug it, then tie it with a plastic bag and plate it for easy transportation.

Installation After determining the position of the internal and external units, immediately install the hanging plates of the indoor unit. After the hanging plates of the outdoor unit and the indoor unit are firmly installed, straighten the connecting pipes and check whether there are any bends in the pipes; next, check the speakers at both ends. If there is a crack, it should be re-expanded, otherwise fluorine will leak. Finally, check the control line and determine the pipeline and control. After the lines and outlet pipes are in good condition, tie them together and seal the connecting pipe openings. When passing through the wall, two people should work together inside and outside the wall to avoid strain; connect the pipes to the internal and external machines, and Connect the control line. Next, remove the air from the pipe and the internal machine as follows:

(1) Tighten the connected external machine joint (thin), and use a special wrench to loosen the stem of the stop valve about 1 turn

(2) Hear the squeaking sound of the outdoor machine joint (thick) for about 30 seconds , use a hand to tighten the (thick) joint

(3) Loosen the stem of the check valve on the (thick) pipe

(4) Completely loosen the valve stem of the stop valve on the (thin) pipe. At this time, the emptying of the vacuum chamber is completed

(5) Finally, use detergent to detect leaks and carefully observe whether there are bubbles emerging from each joint. After verifying that there is no leakage in the system, tighten the valve safety cap and start the test run

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

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