Compared to other air conditioning devices, the split system has a more complex two-block design. This system consists of an external compressor-condenser module and an internal evaporator module with a corresponding number of communications through which freon and electricity are supplied and condensate is discharged. This scheme complicates installation, but does not exclude self-installation. To install such an air conditioner yourself, just read the instructions, make up for the lack of knowledge and experience through Internet resources, and consult with specialists.
Installation features depend on the design of the indoor module, which can be wall-mounted or floor-mounted. To save space in small apartments they usually use wall mounted air conditioner. This split is somewhat more difficult to install due to the need for durable wall mounting. But regardless of the details, the work is carried out in the following sequence:
To install the split yourself you will need a tool. It is recommended to include in the set:
Before installing split system modules, it is necessary to correctly determine their location. For the external unit, the space should be:
Here such a situation is excluded, and the necessary protection of the unit is provided by the visor. An additional advantage is ease of maintenance. When choosing a location for the compressor you need to:
A split system, even in its most low-power version, requires at least 1.5 kW. Such power requires a separate line, unloaded by other consumers, especially in houses earlier than 1990.
It requires:
If you plan to hide the wiring in a groove, then you should take care of this during the renovation so as not to spoil the expensive interior of the renovated apartment. When the idea to install a split came after a renovation, the solution may be to install additional wiring in the box. In any case, this will allow:
The complexity of this stage depends on the location where you decide to place the air conditioner. Three options can be used:
On the balcony, it is enough to install short brackets and place the module on them. The protection function will be performed by a standard balcony canopy.
When choosing a loggia, you can limit yourself to the same brackets, but you should remember that a closed space does not provide the necessary air circulation, which will damage the air conditioner.
Open doors will help avoid this, which reduces the value of the loggia especially in winter time. It is impossible to mount the module on the wall without reinforced brackets, which must confidently support a weight several times greater than the mass of the unit itself. To attach them, it is better to use long anchors with a diameter of 20 mm.
Before installing it, you need to mark the mounting locations. Check them horizontally and vertically using a level. After this, the work is performed in the following order:
Having completed the above work, you can install the external unit on the previously fixed brackets and lead the route to it. Excessive force should be avoided when bending the tubes to avoid deformation and wrinkles (the permissible bending radius is at least 100 mm). If the air conditioner hangs over the sidewalk, then you need to take care alternative options removal of condensate indoors.
It is impossible to install a split correctly without sealing and vacuuming the communications. Sealing of connections is carried out using a soap solution and a conventional bicycle pump. The solution is applied to the connections and the tubes are pumped using a pump. When bubbles appear, carefully tighten the nuts by 1/8. The procedure is performed until the bubbling stops.
Then vacuuming is performed, which removes air, dust and remaining moisture. For this:
Before checking, fill the split with freon or refrigerant, depending on the requirements of the instructions, to the specified pressure. Testing is activated using a circuit breaker. At correct execution After installing the air conditioner, it will automatically enter test mode. Its result should be:
If all the signs are present, the split can be used every day. Otherwise, you will need to contact specialists. In this case, the warranty for the air conditioner will be lost.
So it is still not recommended to install such an air conditioner yourself. It’s better to immediately weigh your strengths and think about inviting a specialist.
With him in the apartment, the heat in the summer is okay, and the dampness in the fall, when it rains coldly, and the heating system is not yet working. After purchasing and installing an air conditioner, the next stage begins: connecting the air conditioner to power.
This work should be carried out according to the diagrams shown, located on the covers of the air conditioner modules. There is also an instruction manual with power and connection requirements.
The design of a standard climate system includes an outdoor module, which is located outside the window, and an indoor module. Sometimes two indoor or outdoor modules are installed.
Each component of this system performs its own specific tasks. For example, the external module is responsible for condensation, and the internal module ensures the evaporation of water. The modules are interconnected by pipelines and electrical wiring. Freon circulates in the tubes.
The drainage tube is connected to the external module. Condensing moisture is removed through it during system operation. According to the rules, the drainage pipe must be connected to the sewer system of the house.
The retail chain has a wide selection of climate systems that can satisfy the tastes of any customer. But their design, operating principle and connection methods do not differ much from each other.
Connecting an air conditioner to the network in an apartment or house is very different from similar connections at production facilities or offices. Household air conditioners are connected only using a single-phase circuit.
The first method is suitable for any household appliances; most often they are connected using this method. Any split system is independently connected in several stages. This order must be followed.
The figure shows the connection of the modules. You will also need an electrical diagram of the split system you purchased.
The internal air conditioner module must be connected to a reinforced socket, installing a circuit breaker near it. It is necessary to take into account that the air conditioner operates in different modes, so its power can significantly decrease and increase, depending on the type of mode. Therefore, the air conditioner power circuit must have separate protection.
Similar information is available at inner surface evaporator covers and on the outdoor unit housing. This greatly simplifies connecting the air conditioner at home.
There is a special box under the front panel of the evaporator. It contains terminals for connecting wires. This system module is always installed indoors.
Conductors from the evaporator are connected to the terminals of the external module. In this case, you should be guided by the numbers of terminals and wires. The ends of unused conductors must be carefully insulated. In order to correctly understand the principle of operation and understand everything, you need to be guided by the circuit diagram.
The integrity of the wire core insulation is the key to the safe operation of the entire system. Therefore, before electrical connection It is necessary to inspect the core insulation for damage.
If you cannot understand the operation of a split system, and have never dealt with such connections, then it is better to seek help from specialists rather than try to do this work yourself .
The split system is a sensitive device. Therefore, it requires a working electrical network to ensure its normal operation. Otherwise, you will waste your money and end up with expensive repairs.
Professionals advise using the safest and most reliable way split system connection: separate cable. This will ensure stable operation of the equipment. An individual line allows the system blocks to be located in any convenient places. When installing a residual current device, protection against current overload of the network will be provided.
Harnesses electrical cables enclosed in a protective sleeve, then placed in a special plastic box, fixed to the wall surface.
Modern Euro electrical sockets are the most suitable for connecting high-power home appliances. In order to maintain the warranty on the split system equipment, it is advisable to connect it to the power supply by a qualified specialist authorized to perform such work. If you connect yourself, the warranty will be void.
When installing an air conditioner that has been removed from another location and does not have a warranty, you can connect it yourself, carefully following all the recommendations.
To ensure quality independent connection air conditioner, it is necessary to use a wire that meets the requirements of the manufacturer. Usually household electrical devices connected with a wire with a cross-section from 1.5 to 2.5 mm 2. In this case, the permissible current can reach 18 A. For a wire length of up to 10 meters, a wire cross-section of 1.5 mm 2 is sufficient; when the length increases, a wire with a larger cross-section is used.
Usage aluminum wire to connect the air conditioning system is prohibited. For a single-phase connection option, a three-wire wire is used, and for a three-phase connection, a five-wire wire is used.
Do not lay the power cable of the air conditioner near heating pipes or gas pipes. The distance between them must be at least one meter.
The general principle of connecting different blocks of the system is the same, apart from some features.
Insert the bare ends of the wires into the corresponding holes in the terminals and secure with screws.
After connecting both units, it is necessary to finally check the correctness of the connection diagram. After a thorough check, a performance test is performed and the air conditioner is connected for a short time.
Errors when connecting a split system can lead to equipment malfunctions and failure of individual elements.

We all want to make our home as comfortable as possible. One of the indicators of comfort is temperature regime. An air conditioner will help us maintain the desired air temperature in the house.
The air conditioner connection diagram is of interest to many, since they are often installed in houses and apartments, as well as in offices, shopping and entertainment complexes and other institutions. Therefore, today we devote our article to such a topic as connecting an air conditioner with your own hands. In it we will tell you how to connect an air conditioner from an outlet, and also consider connecting a split system directly.
As always, we remind you that work related to electrical installations should be carried out only in compliance with safety regulations. It should also be noted that connecting the air conditioner to the electrical network must be done in accordance with the connection diagram (it is available in the passport of the electrical appliance).
To connect a landline or mobile air conditioner from the socket we will need:
Power cable with 3 copper cores with a cross-section of 2.5 mm² (for example, a cable produced by Cable-Arsenal LLC). The product of this plant has the following color markings for the cores: white, blue, yellow-green (g/g);
. SCHUKO type socket with grounding contact;
. three-core PVA wire with a cross-section of 1.5 mm² and a plug (if the connecting wire is not supplied with the air conditioner). For these purposes, a cable from Cable-Arsenal LLC is suitable - 3x1.5-0.38 with this color coded veins: brown, blue and yellow-green (w/g);
. circuit breaker(if it was not previously installed in the apartment panel).
In a pre-prepared groove from the shield to the installation box, we lay the VVG cable so that the end of the cable in it has a reserve length for reconnection.
Please note that it is recommended to install the socket at a height convenient for use.

After laying and fixing the cable, we carry it out in the shield connection in the following sequence:
Lived with insulation white- free terminal of the machine;
. blue core - free terminal of the zero bus;
. conductor of yellow/green color - any terminal of the grounding bus.
After laying the cables, we perform Finishing work and proceed to the installation of electrical accessories. In the installation box we strip the cable and We connect the socket:
Veins of white and blue colors- extreme terminal of the socket;
. conductor of yellow/grey color - central terminal marked “PE” or.
If there is no connecting wire included with the air conditioner, then take the PVS wire, measure the required length and proceed to install the plug. To do this, we unwind it, pass the wire into a special hole in the housing, clean it, terminate the stranded wires and connect:
Cores with brown and blue insulation - to the outer bolted connections of the plug;
. yellow-green vein - to the central bolted connection plugs with markings.
After making the connection, fix the wire with a special bracket and assemble the plug.
Having disconnected the plug, we proceed to connecting the air conditioner. First you need to remove (lift) the panel, unscrew the screws holding the cover of the air conditioner terminal box, and remove it. We pass the second end of the wire through a special hole, strip it, terminate the stranded wires and
Lived with insulation Brown- to terminal “L”;
. blue wire - to terminal “N”;
. the yellow-green core - to the terminal with the sign or marking “PE”.
Now let's look at how to connect the air conditioner to the electrical network directly. To connect the air conditioner in this way, you must use the same cable as in the previous connection option.
We lay it in a pre-prepared groove to the intended installation location of the indoor unit of the air conditioner. In this case, the end of the cable must have a reserve length for reconnection. After laying and fixing the cable, we connect it in the panel in the same way as the previous option.

After this, work is carried out on laying communications to connect the outdoor unit and finishing work. Next, the outdoor and indoor units of the air conditioner are installed and connected. When installing the indoor unit, remove front panel, unscrew the screws holding the terminal box cover and remove it. We pass the end of the cable through a special hole, strip it and connect to a special terminal block:
Core with white insulation - terminal “L”;
. blue wire - terminal “N”;
. yellow-green core - terminal with a sign or marking “PE”.
Close the lid, tighten the screws, and then close the panel.
So, we have connected the air conditioner to the electrical network. you also can watch our video, which shows in detail how to connect an air conditioner with your own hands.
It's hard to imagine modern life no air conditioning. Almost every home has an air conditioner. But if you have just purchased an air conditioner or are planning to purchase it, then you need to know that the installation of the air conditioner is carried out according to a certain scheme, which is proposed by specialists who install air conditioners. Basically, the air conditioner connection diagram corresponds to the requirements of the room and the wishes of the client. Some amendments may be made to the installation diagram for, for example, a non-standard split system or a room with a number of features.
Each client wants the installation of an air conditioner to be carried out economically, and its further maintenance to be quick and without additional material costs. A typical air conditioner connection diagram involves placing the indoor air conditioner unit on the wall adjacent to the window, which allows the use of a limited amount of materials, which in turn reduces installation costs.
In addition, this arrangement of indoor and outdoor units allows the split system to work more efficiently and consume less electricity. In addition, the load on the compressor with this arrangement of blocks is reduced, thereby increasing its service life. The external unit of the air conditioner is usually placed under the window, which allows such installation to be carried out without additional funds. Moreover, in the future, servicing air conditioners located in this way is much easier, faster and without the use of additional technical means.
Connecting communications are laid between the internal and external blocks, which are hidden in the decorative plastic block. To hide the block at the entrance to the room, use design techniques. The internal unit of the split system is connected to the electrical network by using an outlet or distribution board. In any case, the cable is hidden in a plastic block. Sometimes it is recommended to connect air conditioning systems via an automatic machine, which requires certain measures that may be impossible due to the distant placement of the switchboard. Then, the only one possible way connecting the air conditioner is to use the closest outlet. This air conditioner connection diagram is the most economical and optimal. It can be used in most cases.
Depending on the power of the air conditioner, it can be built into an existing electrical network or connect to the air conditioner separate line. Be sure to install machine, regardless of whether it is a separate line or a nearby outlet. Wires can be laid together with copper tubes in grooves or decorative boxes.
We need to start by determining exactly how The air conditioner will be connected to the house's electrical network.
There are only two options:
You can connect to existing wiring in the location closest to the air conditioner if:
If the air conditioner is connected to the nearest outlet, the network must be equipped with an RCD and differential. automatic - the air conditioner consumes a lot of electricity over a long period of time. When connecting the air conditioner to the network, be sure to install a 20A or higher circuit breaker at the point where it is turned on.
A separate power supply line is a more preferable option for connecting air conditioners. This will protect the existing network and unit from overloads and voltage fluctuations. A separate line will allow you to supply current directly to the air conditioner, therefore this does not affect its location.
Requirements for a separate power supply line:
It is not advisable to include other units in the line along with the air conditioner. Appliances and lighting. Connect additional systems: heating the air conditioner drainage, heating the external unit, acceptable. It makes no sense to install an RCD and a differential circuit breaker on a separate power supply line.
It is also necessary to provide power supply from the indoor unit of the air conditioner to the outdoor one. if possible, the cable can be laid together with the freon interconnect route.
When connecting the air conditioner, you must follow operating instructions, which, among other things, indicates exactly how to connect electric wires. The instructions also provide detailed diagram wiring connections for that specific model.
The second solution is to obtain information for installing a specific air conditioner - electrical diagram shown at inside air conditioner unit covers, or on the blocks themselves. It details how it is necessary to connect the air conditioner units to each other and how to connect the split system to the existing electrical network.
Let's look at the most common sequence for connecting a home air conditioner.
We connect the power wire to the mounting block. IN mounting block air conditioner, the power cable must be connected strictly according to the diagram on the cover.
Black the wire that comes from the machine is connected to terminal L
Blue the wire is connected to terminal N
Yellow-green the wire is connected to the ground of the air conditioner
The connection of the outdoor unit must be carried out following the user manual or the diagram located on the air conditioner. The split system units are connected to each other using a power cable with a cross-section no less than that indicated on the cover.
Carry out the electrical installation slowly and strictly adhere to the diagram. Place electrical cables in grooves and decorative boxes, not openly, use corrugated pipe suitable diameter. This will allow you to remove or replace the wires if necessary. If you put the drainage together with the cable, do not neglect to hide the cable in a corrugated tube.

Until this time, I had been suffering from the heat for a long time, because our air conditioner had deteriorated, and no one lived here except me, I still didn’t want to call a repairman, I thought to myself. After reading your article, I was easily able to understand what the problem was, thanks to you and yours wonderful section.
Installing an air conditioner is a rather complex undertaking that requires, if not experience in carrying out such work, then at least thorough theoretical training. In more than half of the cases, problems with air conditioning appear due to incorrect installation and errors during the system connection process. Even the most expensive and modern device will not be able to fully realize its potential if its installation is carried out in violation of technology.
A traditional split system includes an external unit, which is placed outside the window, and an internal unit. In some cases, more than 1 block is installed. Such combinations are known as multi-split systems.
Each element of the system performs its own functions. So, outdoor unit is responsible for condensation, while the internal one acts as an evaporator. The blocks are connected using a backbone of tubes and wires. Freon circulates through the tubes. The system also includes a drainage tube. It is connected to the outdoor unit. It is responsible for removing moisture that condenses during operation of the installation. According to the rules, this tube must be connected to the sewer system.
Air conditioning systems are available for sale to suit every taste and requirement. However, in terms of their composition and connection technology, they are practically no different from each other.
Before you begin installing the blocks, you need to decide on a number of important points.
It is important to ensure normal access to blocks for execution preventative work And repair activities. The outdoor unit must be protected from precipitation, icing and other adverse influences.
When choosing the power of a future split system, take into account operational and other important characteristics housing. First of all, take into account the orientation of the apartment or house to the cardinal points. Also important is the number of people inhabiting the home, the total power of electrical appliances, the number of heating radiators, the presence of other ventilation systems and devices.
Before proceeding with the installation of the outdoor unit, you need to make sure that the strength of the balcony railing or wall is sufficient to support the weight of the product. The most powerful models weigh up to 60 kg or even more. On average, household outdoor units weigh 10-15 kg and usually no problems arise with their placement. The wall and all fasteners used must have a minimum of two times the strength factor.
If there is external insulation, be sure to ensure that the brackets are not attached to the thermal insulation, but directly to the wall material.
Quite often, aerated concrete is used in modern housing construction. This excellent material with high thermal insulation properties, however, unfortunately, it cannot boast of great strength. If external walls Since your home is built specifically from aerated concrete, you should refrain from installing the air conditioner directly on the wall.
It is not recommended to hang the block on a ventilated façade., because During its operation, quite strong vibration and noise can be created. In the situations described, the unit should be installed using a special damping seal, which is pre-fixed to the wall. The air conditioner itself rarely produces noise more than 25-30 dB, so in houses with walls made of a material denser than aerated concrete, no inconvenience usually occurs.
Any distortions when installing the external unit are unacceptable. At each stage of installation, you need to check the horizontal installation of the product using building level. Deviations from the horizontal will lead to disruption of the circulation of freon or other refrigerant used.
If possible, the air conditioner should be installed in a place where the wind blows from all sides, but at the same time it is protected from precipitation and other negative influences. The best option is to place the unit under a pre-installed canopy or at least on the balcony. Residents of the upper floors apartment buildings can install an outdoor air conditioner unit on the roof. It is only important to ensure that the main length does not exceed 15-20 m in total. Otherwise, there will be significant losses of cold in the system, and the air conditioner will consume electricity in vain.
Take care to properly arrange the drainage of condensed moisture. Regulations require that this pipe be connected to a sewer. However, this requirement is almost never met, and the moisture simply drips onto the ground under the window. In such a situation, you need to at least make sure that water does not drip on passers-by.
The rules require that the distance between the outdoor unit and the wall surface be at least 10 cm. The problem is that the compressor must have sufficient airflow from all sides. If you install it closer than 10 cm to the wall, in summer the airflow will be insufficient, which will lead to damage to the unit.
Installing an outdoor unit is associated with a certain danger, because... This is still high-altitude work. Therefore, installation can only be carried out if you have the necessary insurance, or it is better to completely entrust it to professional installers.
Inside the premises, the corresponding unit is installed and the pipeline is laid. Special attention should be paid to the process of arranging electrical wiring. Household air conditioners consume about 2 kW of electricity or more. First make sure that the wiring in your apartment or house can withstand such a load. If she is not capable of this, lay an individual line from the shield with a separate fuse. This will protect the wiring from overheating and your property from fire.
Lay the line from the external unit of the air conditioning system to the location of the indoor unit. The line can be laid outside or inside. When installed externally, it is hidden in a plastic box, in accordance with internal installation the line needs to be buried in the wall.
Be careful when choosing a place to place the indoor unit. The further the blocks are removed from each other, the less efficient the system will be and the higher the energy losses will be.
The indoor unit must be placed so that there are no objects near it that could interfere with the normal flow of cooled air. Appliances, curtains and other objects that are at the same height as the unit must be at least 3 m away from it.
The unit must not be placed directly above a heating radiator. The installation location must be such that the installation can be easily accessed for repair and maintenance work. The distance between the unit and the ceiling should be at least 20-25 cm. It is not recommended to install the air conditioner above appliances and furniture.
The air conditioner must be installed so that the output during operation cold air did not blow directly on the person. Otherwise, bronchitis and sore throats will not take long to appear.
The indoor unit may have a wall or ceiling structure. The latter are extremely rare. However, regardless of the type of system, it is necessary to ensure the most correct and reliable fastening. Installation is carried out using brackets and screws. Brackets must be checked for strength.
After connecting the outdoor and indoor units, it is necessary to remove moisture and air from the line. This process is known as vacuumization. Special equipment is used to pump out air and water.
Air conditioner installation is carried out in several stages. First, the electrical wiring is laid. Further the external unit of the system is installed. The technology requires that it be placed at a height of at least 180-200 cm from ground level. This requirement is relevant for owners of private houses and residents of apartments located on the ground floor.
IN external wall holes are drilled for laying communications. The diameter of these holes should be 500-600 mm. Brackets are installed to ensure the block is secured. A special waterproofing cup is inserted into the prepared hole and the connecting lines are laid directly.
Next you need install the indoor unit. The maximum permissible distance between these two elements is 20 m. A distance of 7-12 m is considered optimal. Specific recommendations are given in the instructions for the equipment; be sure to study it before installation. Install the brackets and secure the indoor unit of the air conditioning system.
At the end, all that remains is to lay the wires that will ensure the functioning of the system. Mount the box. It, as already noted, can be internal or external. Connect the electrical wires and freon tubes. Evacuate the system. Special equipment is used for this. The procedure itself lasts on average 45-60 minutes.
After vacuuming is complete, perform test run air conditioner Professionals at this stage use special software and hardware equipment. If it is absent, at least observe the operation of the system and the state of the electrical network for some time.
Mistakes made during the installation of an air conditioner entail many various troubles. However, services professional installers every year they become more expensive and everything larger number In an attempt to save money, people try to install air conditioning themselves. This, as already noted, is a rather complex and very responsible job, which has many features and requires taking into account a wide variety of nuances.
If these and any other errors were made and led to undesirable consequences, appropriate measures must be taken to correct the violations. If there is a draft from the air conditioner, it is usually enough to change the direction of air flow by adjusting the dampers.
When the system is turned on in heating mode external unit Ice is often found. The reason for this phenomenon is usually that the system does not have an automatic defrost function. To remove ice, it is enough to turn on the equipment for a while to cool. The air conditioner will heat up and the ice will disappear.
If your air conditioner stops cooling properly, you need to check the filters. They require regular cleaning. Detailed recommendations about this are usually given in the instructions.
If water starts dripping from the indoor unit, the cause of this problem in most cases is severe clogging drainage channel. Ice plugs that form also lead to this. It is impossible to eliminate this kind of blockage on your own without the necessary skills. It is recommended to urgently call a technician who can properly warm up the system and correct the situation.
Uncharacteristic noises during system operation usually indicate an imbalance of the fan or severe wear of the bearings. This problem can also be dealt with only by a qualified technician.
If you find that the air conditioner has begun to overheat, you should call a technician to check the freon level and the tightness of the system.
Thus, self installation and connecting the air conditioner is a completely doable job. But you need to be prepared in advance for the fact that this event is not easy. Follow the instructions in everything and promptly eliminate any problems that arise. Then the air conditioner will serve as long as possible, fully performing all the tasks assigned to it.
Good luck!
