The knowledge of how to remove the air conditioner from the wall with your own hands may be needed in several cases:
- if you plan to move;
- if it is necessary to carry out repair and restoration work;
- if it is planned to replace the air conditioner with a new one and there is no desire to pay for dismantling the old one.
To begin with, when changing the location, it is worthwhile to deal with completely disconnecting the air conditioner from the wall, that is, both blocks. In this case, it is important not only to make high-quality dismantling, but also to comply with the rules for transporting split-system modules.
How to remove the outdoor unit from the wall
First of all, they provide for the availability of the necessary tools. To remove the air conditioner yourself, you will need:
- adjustable or gas wrench;
- hexagons;
- open-end and socket wrenches;
- indicator screwdriver;
- pipe cutter;
- manometer or gauge station.
Nippers and similar tools cannot be used instead of a pipe cutter, as they spoil the quality of the copper pipeline.
First, dismantle the external module - the condensing unit or KKB.
Step 1. The valve plugs are opened with an adjustable or wrench on the front side of the KKB.
Step 2. Close the liquid valve of the outdoor unit. Use a hex wrench.
Step 3. In order for all the freon to go to the external module, the air conditioner is started in cooling mode for 30-40 seconds. As soon as the compressor began to work only for suction, a gauge station is connected to the valve from the gas pipeline and they wait for the readings to reset to zero. Immediately close the freon return valve.
Step 4. The system is completely de-energized. Before proceeding to the next stage of removing the air conditioner from the wall, check the absence of current with an indicator screwdriver by inserting it into the terminal with a phase.
Step 5. Now the freon line is cut with a pipe cutter, since it is a non-removable structural element. The remaining ends must be insulated from moisture and debris. To do this, you can use electrical tape.
The connecting tubes are cut at a distance of 15-20 cm from the fittings. If the dismantling of the capacitor module is carried out for the purpose of carrying out repair and restoration work, then there is no need to cut the copper pipes.
Step 6... Disconnect the drain piping and interconnect wires carefully. It is also advisable to wrap the ends of the electrical wires and the drainage tube with protective material.
Step 7... Now they begin to dismantle the device itself. How to properly remove the outdoor unit of the air conditioner from the brackets? Use an open-end wrench or socket wrench to disconnect it from the nuts and bolts. Since the KKB usually has a lot of weight, it is advisable to take a second person as an assistant.
Step 8... The brackets are removed from the surface of the building or balcony by unscrewing the shut-off valves with a socket head.
After the air conditioner has already been removed from the wall, proceed to packing it. To do this, you need a multi-layer cardboard box, styrofoam and a roll of soft wrap film.
The KKB can only be transported in an upright position to avoid water hammer during subsequent work. Before mounting the unit in a new place, let it stand for 2-3 hours.
If transportation is planned for the winter, you need to dismantle the air conditioner from the wall so that all the freon does not leak out.For this, a gauge station must be used. But most experts advise draining the refrigerant and then completely recharging the circuit.
How to remove an air conditioner compressor
The most serious malfunction of a split system can be a compressor breakdown. It occurs when:
- poorly performed installation - lack of evacuation, violation of the rules for laying the freon pipeline;
- using a split system in an unacceptable temperature range;
- factory marriage.
In this case, you will also have to independently remove the air conditioner KKB and disassemble it. Some climatic technicians do without complete dismantling, but it is problematic for a layman to do this, since in this version access to many elements is severely limited.
The outdoor unit has been removed, now how to remove the A / C compressor? In fact, there is nothing supernatural here:
- The protective cover is removed from the case of the outdoor unit;
- Disconnect the lines going to the discharge and suction, as well as the electrical wires suitable for the fan and compressor;
- Unscrew the fasteners with an open-end or socket wrench and remove the compressor from the vibration dampers.
It is worth considering that before removing the air conditioning compressor, it is necessary to check the degree of deterioration of the oil. If it has an unpleasant odor and changes color during oxidation testing, then replacement + rinsing of the KKB will be required. Under normal conditions and a negative oil oxidation test, a simple change will suffice.
How to remove the indoor unit from the mounting plate
With how to remove the air conditioner compressor and the outdoor unit itself from the wall, everything is clear. It remains to figure out how to dismantle the indoor module. This process also takes place in several stages:
- Remove the protective cover from the case;
- Unscrew the fasteners;
- Disconnect all connecting communications: freon line, electrical interconnect cables, drainage pipeline. Turn off the power beforehand;
- The block is removed from the plate by opening the fastening latches;
- Unscrew the mounting plate and dismantle the plastic wire with the remaining copper tubes.
When removing the indoor unit of the air conditioner from the wall, be very careful not to damage the fastening latches that hold the unit to the mounting plate.
Be sure to stamp the ends of the copper freon tubes in the same way as in the external block.
The room module is packed in a dense cardboard box, overlaid with foam and wrapped in a soft bubble wrap. The evaporating unit can be transported in any position, unlike the KKB.
If it is required to replace or clean any element of the indoor unit of the air conditioner, then it may also need to be removed from the wall or partially disassembled into components. It looks like this:
- Remove the bezel and wash the back of the bezel with a stream of water and detergent or soap;
- Remove the air flow guide plates by taking them out neatly from the grooves. Some models have special latches for this;
- Unscrew the screws, gently pull the lower protective part towards you and slightly raise its top, then remove it from the latches;
- Disconnect the supply wire and drainage;
- Disconnect the interconnect wires from the corresponding terminals, having previously recorded their location;
- Remove the hose tray. For some models, it can be stationary, then it is lowered a little;
- Now remove the tangential fan by lifting up the evaporative heat exchanger.
All elements are washed with water and a cleaning agent. You can use a steam generator for a more thorough cleaning. When the parts are dry, they are fixed in reverse order in place.
If it is required to dismantle the control board, then first remove the protective cover from the electronic unit, disconnect all wires (connectors of the indicators of the indicator panel, the air damper drive). After that, the board is unscrewed from the fasteners with a screwdriver or simply disconnected from the latches.
When the indoor unit is not dismantled, but disassembled, there is no need to cut off the freon line.
Monoblock systems are dismantled in almost the same way. The only difference is a slightly different circuit diagram and pipes with a working fluid.
When self-dismantling is undesirable
Do not remove the air conditioner with your own hands in the following cases:
- in the presence of a column-type, channel-type or cassette-type split system;
- if the user does not have the necessary tools, materials and instructions for the device;
- with a person's uncertainty in their own abilities.
In these situations, it is better to contact professional installers.
Before proceeding with independent actions, you can watch a video on how to remove the air conditioner yourself:
