How to operate a split air conditioner and how to disassemble and assemble a split air conditioner?

The outdoor unit of the air conditioner has two copper pipes, one thin (exhaust) and one thick (return). A set of Allen wrenches and a movable wrench are required. First power on the air conditioner, turn on the machine, refrigerate, set the temperature to a low point, turn on the machine for one minute, there is a three-way control valve on the thin copper pipe (gas outlet) of the outdoor unit, twist the copper nut off with a movable wrench, pay attention, it is the nut facing outward, not the one facing down, the one facing down is used to exhaust air when the machine is installed!

Then use the hexagon to tighten the valve (clockwise). The purpose of this is to prevent the outdoor unit from coming out of the gas, so that the fluorine can not come out, about a minute or two later, and then tighten the valve of the thick copper pipe, the method is the same as above, because after a minute or two, the chlorine is also finished! Tighten the valve of the thick copper tube and shut it down at the same time!

At this time, the fluorine is received into the compressor of the outdoor unit! Finally, you can remove the two copper pipes connected to the outdoor unit! After removing the copper pipe, it is best to wrap the copper pipe nozzle in a plastic bag to avoid water or dust entering the copper pipe!

Finally, you can remove the outdoor unit and indoor unit! Succeed with flying colors!

Turn on the air conditioner to the refrigeration state, turn off the high-pressure valve, turn off the low-pressure valve after running for five minutes, then turn off the air conditioner and cut off the power, remove the pipeline, and finally remove the circuit cable.

Disassembling and assembling split air conditioners requires preliminary work first. Close the high-pressure valve of the outdoor unit (the one connected to the thinner copper pipe). Start the air conditioner for 3 minutes and add the refrigerant** to the outdoor unit.

Close Close the low-pressure valve of the outdoor unit (the one connected to the thicker copper pipe) and shut down. Close the two valves of the indoor unit. Remove the power supply and keep a record.

Remove the pipeline, and plug the end to protect the Senyu socks.

Steps to install a split air conditioner:

1.Install the unit and connect the circuits and piping according to the dismantling record.

2.Open the two valves of the indoor unit, 3Open the high-pressure valve of the outdoor unit and exhaust the low-pressure valve once.

4.Turn on the machine to see the refrigeration effect, if it is not good, it is necessary to supplement the refrigeration.

Air conditioning will be available in every home now, but in fact, air conditioning is also divided into many kinds, such as window air conditioning and split air conditioning. There is a popular saying in the air conditioning industry that "air conditioners are three points of quality, and seven points of installation". So let's find out togetherSplit air conditioningHow to install and how to disassemble the split air conditioner.

1. How to install a split air conditioner.

1. First of all, we need to adjust the system pipeline inside the machine. The installation of split air conditioners must regularly clean the pipes of the indoor unit system of the air conditioner to discharge rust, dust and other debris; Regularly add chemicals to the system to prevent rust from the copper pipes. This can effectively avoid the occurrence of split air conditioner blockage, and is also conducive to improving the service life of the air conditioner.

2. Then we need to fill and exhaust in time. The installation of split air conditioners requires that the indoor unit of the air conditioner is filled with water, and the air is regularly exhausted for the split air conditioner; Also regularly check whether the exhaust valve of the split air conditioner is in good condition. If the exhaust valve of the split air conditioner fails to fail, it will be easy to cause blockage.

3. Adjust the temperature meter of the air conditioner. The installation of split air conditioner first requires the operator to pay more attention to whether the temperature of the instrument is normal, and if the temperature of the split air conditioning instrument is abnormal, it must be dealt with in time. When the temperature is relatively low and calm, we should appropriately increase the opening of the hot water valve.

4. Preheat before use. When installing a split air conditioner, in addition to adding an interlocking electric thermal insulation air volume regulating valve at the fresh air inlet of the indoor unit of the air conditioner, a preheater should be installed between the distance from the fresh air to the surface cooler. In winter, the outdoor fresh air temperature is raised to above zero degrees and then comes into contact with the surface cooler, so that in the event of other unexpected situations such as power failure, failure of the circulating water pump or blockage of the surface cooler, it will not pose a threat to the surface cooler.

2. How to disassemble the split air conditioner.

1. The wrench unscrews the connecting lock nut of the indoor unit, and uses the prepared sealing sodium to unscrew the silk pattern of the connecting joint of the indoor unit to prevent the silk pattern of the joint from being damaged during handling; Then use the cross to remove the control line. At the same time, it is necessary to mark well to avoid the wrong connection during installation. If the signal line 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.

2. After unscrewing the connecting lock nut of the external machine, then the sealing sodium screws are screwed to protect 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 to avoid vibration and bump.

Slowly straighten the pipes of the outdoor air conditioner and seal the four ports of the connecting pipe with the prepared four plugs to prevent dust and moisture from entering the air. The plug is good, and finally tied with a plastic bag and placed for easy handling.

The above content is based on how to install the split air conditioner and how to disassemble the split air conditioner, I don't know if you have a certain understanding of how to install the split air conditioner after reading this article.

Hello! Air conditioner disassembly and reinstallation (common method).

1. Fluoride collection. After the compressor works, close the high-pressure valve and run for one minute, close the low-pressure valve and stop the machine. Unplug (remember!!

2. Disassemble the copper pipe joint of the outdoor unit (wrapped in plastic cloth to prevent soil from entering), and disassemble the outdoor mechanical and electrical wire joint (remember the order of the line).

3. Remove the indoor and outdoor units.

Installation: 1. According to the position of the indoor unit, hit the wall eye of the pipe, nail the hanging plate of the indoor unit at the predetermined position (the level must be guaranteed and corrected with a level), and hang the indoor unit after the tube is pierced;

2. Determine the position of the outdoor unit according to the length of the tube, and the outdoor unit should also ensure the level;

3. Connect the high and low pressure pipes, open the high-pressure valve first, then loosen the lock nut of the low-pressure pipe (discharge the air in the pipeline), tighten the lock nut after hearing the sound of gas outlet for 8 10 seconds, open the low-pressure valve, and connect the wires in order.

4. Turn on the power supply and test the machine. Check the pipe joints (lock nuts) with soapy water for leaks.

Notes:1The copper pipe of the old air conditioner has poor toughness and is easy to become a dead bend;

2.Fluoride collection and air exhaust should be thorough;

3.The internal and external organs should be horizontal and firm, otherwise the noise will be loud;

4.There must be no leaks.

The above is a personal experience, I hope it will be helpful to you. In addition, the above steps are only applicable in summer (the working state of the air conditioner is cooling).

This can be a professional air conditioner, first of all, power on, after the external compressor is running, the frelinquin is collected into the external compressor, the copper pipe switch is turned off, the power is turned off, and then disassembled. Otherwise, all the gas will run away, and it will be filled with fluorine again after the new arrangement

If you are not a professional installer, you better not install it yourself, it is best to find a professional air conditioner staff to install it.

2. Liquid collection steps: first put the air conditioner in the refrigeration state and start running. Open the brass hexagonal bonnet of the high-pressure valve on the outdoor unit, and close the high-pressure valve with an inner hexagon wrench.

At this time, the air conditioner is still running, because the high-pressure valve has been closed, so the refrigerant can no longer flow to the indoor unit through the high-pressure valve for heat exchange, and is compressed into the outdoor unit. When the air conditioner runs for about 3-5 minutes and there is no more cold air blowing out of the indoor unit, it means that the refrigerant has been fully received into the outdoor unit. At this time, close the low-pressure three-way valve on the outdoor unit.

At this point, the refrigerant is enclosed in the outdoor unit. Turn the air conditioner off.

3. At this time, the disassembly operation can be carried out, the connection pipe of the indoor and outdoor machines can be removed, and the cables between the indoor and outdoor machines can be removed.

4. Pay attention to cleaning when removing the Unicom copper pipe, and seal the interface of the pipe mouth and the three-way valve with a plastic bag to avoid the entry of dust and impurities.

1. How to disassemble the indoor and outdoor units of the air conditioner.

1. Before disassembling the air conditioner, the first thing you need to do is to store the refrigerant of the air conditioner, which is very critical.

2. Next, if you want to formally disassemble the indoor unit of the air conditioner, you can disassemble the outdoor unit first, and at the same time pay attention to keeping both sides of the machine level to prevent it from falling.

3. Fix the internal machine in the prepared hole, and the two machines should also pay attention to synchronization to prevent water leakage in the later air conditioner.

4. Disassemble the cable of the air conditioner, as well as the connected pipe, pay attention to the connection of the copper pipe when removing the wire, keep the connected copper pipe clean, and save the pipe mouth, tee and valve.

5. Next, disassemble the indoor unit, unscrew the connecting lock nut, and then store the screws, and then prepare a cross driver to remove the control line of the inner line of the air conditioner, and at the same time, you can remove the panel and filter screen of the air conditioner and put it on the ground.

6. Finally, disassemble the outdoor unit of the air conditioner, open the connecting lock nut of the external unit, then loosen the fixing screws, and finally remove the external unit.

a. After determining the installation position, measure the size of the air conditioner and open the installation hole as requested. If the house has been constructed with reserved holes and brackets for air-conditioners, the reserved holes should be reviewed and modified; In some houses, the reserved holes are completely blocked around the perimeter, and the two sides should be opened to avoid obstruction of air absorption.

b. Fix the mounting bracket: firmly fix the mounting bracket in the predetermined installation position, detect and calibrate it to the level with a level, and the outer side of the mounting bracket should be lower than the inner side 6 10mm. Remove the panel and air filter.

c. Remove the chassis fixing plate, pull the chassis and the various parts fixed on the chassis out of the outer box, then put the casing on the mounting bracket, use the degree meter to detect and calibrate it to the level and fix it with bolts, and then push the chassis and all parts horizontally into the outer box, install the chassis fixing plate and pay attention to the air conditioner should be tilted 6 10mm backward and downward, and install the water outlet to ensure that the condensate can be discharged smoothly.

d. Use a level to check whether the air conditioner is level (whether the base is uneven or even twisted), otherwise there will be abnormal noise and vibration during the operation of the air conditioner, which will affect the relative position of the parts of the air conditioner.

e. Install the air filter and panel and fix them. Check the side air intakes for blockages and fill the perimeter of the case with sponge or foam. Special-shaped fastener drainage:

Generally, condensate will be discharged from the back of the air conditioner, and the installation should be responsible for the direction of drainage, and listen to the user's views to discharge the water into the appropriate place.

f. Grounding: Safety should be the priority to consider, and the power socket should be reviewed to see if it has been effectively grounded during installation. Test run: After all the installation is stopped, it can be powered on for trial operation.

Generally, the refrigerant is transferred to the indoor unit, and then the machine is disassembled, which is best to ask a professional to get it.

The simple method is to use a hot water bottle (30 to 40 degrees Celsius) to heat the temperature sensor of the indoor unit, so that the air conditioner is in a refrigerated state, use an Allen wrench to close the outlet pipe valve of the outdoor unit (the thin copper pipe), wait until the current no longer changes, close the return pipe valve (the thick copper pipe), and then shut down, turn off the power, and disassemble the air conditioner. When installing the air conditioner, after the copper pipe is laid in place, first install the air outlet pipe, the return air pipe is not in a hurry to tighten the copper nut, slowly open the air outlet valve, feel the refrigerant coming out of the air return pipe, quickly tighten the copper nut, and then slowly open the air return pipe valve, wait for the system pressure to balance and then fully open, the air conditioner stands for more than half an hour, and finally check the leak, turn on, and then check the leak. It can be used normally without problems.

The adjustment of the four-way valve is too professional, and it is convenient to use a hot water belt.

Retract the air conditioner first, and then you can disassemble the machine.

You still have to find a professional to do it, outdoor work, safety first, the operation process is not clear in a few words.

Tools required for disassembly: hexagon socket, live wrench, generally Phillips screwdriver operation: 1. The low-pressure pipe (thin tube) of the outdoor unit is closed with the hexagon socket, and the fluorine in the tube is returned to the compressor for 2 to 3 minutes.

2. The high-pressure pipe (thick pipe) of the outdoor unit is closed with an inner hexagon.

3. Use a wrench to remove the low-pressure pipe, high-pressure pipe and outdoor unit.

4. Dismantle the indoor unit and pull out the connecting pipe from the wall and tidy it up.

5. Remove the panel with a Phillips screwdriver. Use a wrench to remove the bracket of the outdoor unit and remove the outdoor unit.

This is the general step of disassembling the air conditioner. It depends on the body and brand.

Steps to relocate and disassemble the air conditioner.

1 **Refrigerant.

Whether it is a winter or summer move, the refrigerant in the air conditioner must be collected into the outdoor unit. Before the air conditioner is moved and disassembled, the air witherer should be started, the refrigeration state can be set by the remote control, and the compressor will run for 5 10 minutes, after the refrigeration state is normal, use a wrench to 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 after l minutes, the surface of the pipe will be condensed, and the low-pressure pipe (coarse) cut-off valve will be closed immediately, and the machine will be shut down quickly, unplug the power plug, and tighten the safety cap with a wrench, so that the refrigerant work is completed. (If it is winter, cover the temperature sensor probe of the indoor unit with a warm towel first, and then control the cold state to set the power on.)

Disassemble the indoor unit. After refrigerant**, the air conditioner can be relocated to the detachable indoor unit. 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. Relocate the air conditioner and disassemble the outdoor unit.

The outdoor unit should be disassembled by a professional refrigeration maintenance worker to ensure safety. After unscrewing the connecting lock nut of the external unit, the prepared sealing sodium should be used to unscrew the silk pattern of the connecting joint of the external unit. Then use a wrench to loosen the fixing screws on the foot of the outer machine.

When the outdoor unit is put down after the air conditioner is moved and disassembled, 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.
