How to install an internal split system unit. How to properly install an air conditioner in an apartment: layout diagrams

Air conditioners are the most popular equipment during the hot season. That is why they are widely used in offices, houses, apartments, etc. Air conditioning systems are characterized by the complexity of installation, so users often turn to specialists for help. If you understand the diagram, you can make a connection.

Installation of indoor and outdoor units

In order to ensure high level performance of air conditioning systems, it is important to correctly install the indoor and outdoor units. Installation of the indoor unit is carried out on special plates, which are supplied in the kit.

The mounting plate is attached to the location where the indoor unit of the air conditioning system is installed. In order to ensure reliable operation block and prevent condensate from leaking out, it is necessary to secure the plates correctly. First, mark the locations of the holes in the plate on the wall and use a hammer drill to drill holes. Dowels are installed in them. The mounting plate is attached to the wall by screwing self-tapping screws into dowels. The final stage is installing the indoor unit on the plate.

The outdoor unit is installed with outside building. To ensure convenience during its maintenance, the mount is made on the side of the window or under it. The outdoor unit of the air conditioner is connected using special device, which is included in the kit.

IMPORTANT! In order to ensure efficient work block, is installed at a distance of 10 centimeters from the wall.

Features of connecting the route

Many people ask how to connect an air conditioner with their own hands. It’s quite easy to do it yourself – you just need to know the air conditioner connection diagram. An important role in it is played by the route, which consists of:

• drainage pipeline;
• power cables;
• equipment management;
• freon line.

Connecting the air conditioner to the electrical network requires measuring the length of the route. 30-50 centimeters are added to this indicator. Initially, copper tubes are wired, which are cut using a pipe cutter.

Attention! When laying copper pipes, using a hacksaw or grinder to cut them is strictly prohibited. This is explained by the fact that during the cutting process with such tools, chips are generated, the entry of which into the air conditioning system leads to its breakdown.

Connecting the air conditioner requires placing the pipelines in a thermally insulating shell before installation, and the holes are closed with plugs to prevent the possibility of dust getting inside. All components of the route are put together and secured with vinyl tape. Next, the route is installed in place.

After the communications have been laid, they begin to connect the freon line and electrical wiring. You can independently connect the air conditioner to the electrical network - the diagram is included in the kit. It shows in detail how to connect the air conditioner to the electrical network.

IMPORTANT! During installation electrical system All actions must be performed strictly according to the scheme. Otherwise, the air conditioner may burn out when first turned on due to a short circuit.

The next step installation is to adjust the length of the tubes and remove burrs. A reamer is used for this purpose. The nut is threaded and each edge of the tubes is flared. Then, we connect the edges of the tubes to the fittings of the indoor and outdoor units. Using a torque wrench, tighten the nuts as efficiently as possible.

WARNING! If the nuts are not tightened enough, they will loosen a little over time, which will negatively affect the operation of the air conditioning system.

After connecting the route, check its tightness. In the video you can see the leak testing technology. Next, moisture and air are removed from the system. For this purpose they use Vacuum pump. Connect it to the service port of the outdoor unit via a pressure gauge corrector. Pumping out air and moisture should be carried out within half an hour. The next step is to fill the circuit with freon.

Warning! If the route is not sealed, a freon leak may occur - common reason breakdowns of air conditioning systems. The air conditioning compressor wiring diagram will show how to tightly connect the route.

Compressor connection features

Let us consider in detail how to connect a compressor from a bk 1500 air conditioner. The connection is made taking into account:

• features of the compressor itself;
• used by the voltage conditioning system;
• power of air conditioning systems.

The air conditioning compressor starts in a few seconds.

Scheme of work

Connecting the air conditioning compressor - simple task. Any of the two compressor outputs are connected to the power supply. A terminal is connected from the third output. Wiring is connected to the second output. We complete the connection of the compressor and check its level of performance. To do this, the air conditioning system is turned on for several minutes and the degree of heating of the compressor is determined.

Attention! If the compressor heats up strongly and quickly, this indicates poor wiring. To correct problems, it is swapped at the compressor outlet.

Automotive air conditioning systems differ from stationary ones. Therefore, when installing them, the connection diagram for the Panasonic air conditioner on the Lada Granta is used. Correct connection of air conditioning systems in vehicle will guarantee its excellent performance.

Example of connecting air conditioning systems

Connection mobile air conditioner is carried out in the same sequence as the stationary one. Connecting to the electrical network with your own hands is done in several stages. Initially, a separate machine intended for the air conditioner is installed in the electrical panel. Next, the phase wire of a three-core cable, which is black or brown in color, is connected to the phase terminal of the machine. The blue cable wire is connected to the neutral bus of the electrical panel. A yellow-green wire, if available, is attached to the ground wire of the electrical wiring.

IMPORTANT! Electrical wiring must be connected correctly. Otherwise, you can cause the air conditioning system to suffer serious damage or complete failure.

In the absence of grounding, use for protection against damage electric shock differential relay. If you don’t know how to connect an air conditioner with your own hands, the video will tell you about it. With its help, you can also learn about the features of connecting a diffuse relay.

If you want to learn how to connect a floor-standing air conditioner, then you must first install its indoor unit. For this purpose, use a three-phase cable with three wires different color:

• black;
• blue;
• green.

Sometimes the color of one wire may be yellow-green. The electrical connection diagram for the air conditioner will tell you in detail about the installation of the indoor unit. The wire, characterized by the presence of a black braid and coming from the machine, is connected to the L-terminal. Wires coming from the automatic switchboard and having Blue colour, are connected to the N terminal. In the internal block of the device, yellow-green colored wiring is connected to the terminal ground. The connection diagram for the Kalina air conditioner shows exactly the same installation of air conditioning systems.

Attention! The external unit of air conditioning systems is connected according to the same scheme. When installing an outdoor unit, wiring with a cross-section of 3x2.5 millimeters is used.

The output circuit breaker is installed on the load current in the electrical panel. When installing electrical wiring, special tubes are used. If electrical wiring is laid together with drainage or near areas where freon leaks, then use a corrugated tube.

It is quite possible to connect the air conditioning system with your own hands. To do this, you must study the instructions and perform all actions in strict accordance with them.

A split system for indoor air conditioning is a more complex system than a conventional air conditioner. But it is worth noting that installing a split system with your own hands is a completely feasible process for every owner of this device.

Installation instructions

The installation instructions for split systems include the following points:

1. Selecting a location for the system.
2. Air conditioner installation.
3. Installing the internal system compartment.
4. First, test run.

Of course, today there are many specialized companies involved in the installation and maintenance of indoor air conditioning systems. But most owners, in order to save money, prefer to independently install the device on site, and subsequently engage in its maintenance; this is possible, even if you did not have any skills before and have not encountered this equipment. It's just worth considering one factor when you install and configure new system yourself, keep in mind that the store’s warranty will no longer apply to such equipment.

Choosing a location for the system

The air conditioning system should be located in a place that will not be subsequently obstructed by anything. Air intakes and air distribution openings must be completely freely accessible.

The outdoor and indoor units should preferably be on the same level. If this is not feasible, then the maximum permissible difference in height should be no more than 5 meters.

As for the wall on which you will hang the blocks, it must be level and strong enough to withstand the considerable weight of the structure. This is why you should avoid installing an air conditioner on interior partitions.

The rules for installing split systems completely exclude direct sunlight to the internal block of the device. The capacitor array itself must be completely protected from direct rays. If the installed outdoor device will be located on the roof, then its front side should be turned towards the shadow side.

It is also necessary to provide conditions for the device drainage system, through which the condensate generated during operation of the installation will be discharged to the street block.

The plastic from which the indoor unit is most often made is very sensitive to known fluorescent lamps, so it is advisable to install the device in a place that is located far from them.

One more thing important condition. The internal compartment must be no closer than 1 meter from microwave oven, since the radiation emitted by the microwave during operation negatively affects the operation of the installation and causes interference.

Choosing a location for the outdoor unit

When installing an external compartment, the most important thing is a strong mount. The wall must be level, fastenings in the form of special brackets must be installed in such a way as to maximally dampen the vibration that occurs during operation of the device.

It is necessary to install the split system yourself so that the outer part of the system is located in a place accessible for subsequent installation and maintenance work. Of course, all air intakes should not be blocked with anything.

Air conditioner installation

Before you begin installing the air conditioner, you need to ensure that you have the necessary tools. You will need the following tools for installing split systems:

• drill hammer;
• pipe cutter;
• flaring tool;
• pump;
• a device that measures pressure in a liquid.

Installation of the device includes the following operations:

1. Initially, you should open the front panel and remove the screws from the cover that covers the electrical unit; it must be pulled out.
2. Connects to the installation electrical cable, and the cover is replaced. A couple of useful notes: the unit itself should not be lower than 2m 30 cm from the floor surface, the socket should be close to the element, and have grounding.

Installation of drainage system

The drainage hose must pass under the connecting pipe. It should not twist or bend. In the future, the hose must be wrapped in thermal insulation materials. Where the drainage route runs close to the wall, it is advisable to lay inserts from thermal insulation material. And the track itself is usually wrapped with felt tape.

Be sure to check the reliability of the joints of the drainage system, as this can subsequently lead to leaks. Next, the pipe is passed through a hole in the wall, and the block, which will be located indoors, is hung on the wall.

It is recommended that technicians adhere to the following restrictions when connecting the pipe line. WITH inside the number of possible bends in the route should not exceed 10 in total. The radius of the most possible bend should not be greater than 10 cm.

The plug from the evaporator tube must only be removed immediately before installation work. First, air is released, then the nut on the connecting tube of the evaporator is unscrewed. It is necessary to apply oil to the joint.

Sealing of holes

Self-installation of a split system must be accompanied by careful sealing of all connecting holes. It all starts with sealing the hole in the wall. Regular standard putty will do for this.

The drainage system pipe is usually tightly fixed using a special clamp. Concerning electrical connection and the cable connecting the blocks for data transmission, then they must be connected in accordance with a special diagram. It is usually attached to the device passport. Depending on the type of installation and manufacturer, the connection must be made.

The cable and data line are connected to the appropriate terminals, which are usually marked in different colors. The cables connecting the two units must also be secured using a special clamp.

During the installation process, be sure to pay attention to the following factors:

• The electrical unit must be securely fixed and closed. If this condition is not met, the risk of electric shock or simple fire increases, since dust, dirt or water can easily get inside.
• Under no circumstances should the electrical connection cable be included with the refrigeration pipe. The cable through which the freon passes heats up during operation of the installation, so contact between them should be avoided.

How to bleed air

Installing a split system with your own hands means that you will also have to bring the system itself into working condition with your own hands. Initially, it is necessary to get rid of air in the system. To do this, you will need to bleed the air from the system.

1. The nut of the service pipe, as well as the plugs on the liquid and gas valves, must be unscrewed.
2. To do this, you need to turn it with a regular hexagon gas valve at 90 degrees. counterclock-wise. Counting down approximately 10 s. turn back and close it. Then apply regular soap solution to check for gas leaks.
3. If you do not find any leaks, repeat the procedure again, but after 10 seconds you do not close it back, but press the fitting for service work. Steam should begin to appear, indicating that air has begun to escape from the system.

Additional refilling with freon

The maximum length of connecting hoses through which freon moves should not be more than 7 meters. But in cases where another installation of the system is impossible for one reason or another, it is necessary to increase the length of the refrigerant route. In this case, it will be necessary to refill the system with freon.

When all the work has been completed and, if necessary, additional freon has been charged into the system, the next step will be the need to do a test run of the installation.

It is advisable to take care of your own safety before taking this action. Pressing the forced start button will activate the system. Sometimes the system beeps twice when turned on. This means that you can control the device using the item remote control. In order to check its operation, you should also press the remote control buttons one by one.

When purchasing a modern split system, the issue of its installation and connection comes to the fore. Usually service departments They offer quite expensive help. Alternative solution You can connect the air conditioner yourself. This procedure seems quite complicated and time-consuming, however, this is only at first glance. In fact, it is quite possible for an ordinary consumer to produce it.

Before acquiring the skills to independently connect, you must first familiarize yourself with the principles of operation of the split system.

Basic operating principles

In order to install correctly and avoid critical errors, you need to know well how the device works.

1. The main part of the device is the refrigerant. Usually it is freon. The refrigerant gradually enters the evaporator container. There, freon is subjected to heat treatment, its expansion and evaporation occurs. Thus, the refrigerant consumes excess heat.
2. Excess moisture enters the radiator in the form of condensation, from there it flows into a special container and is removed from the device through it.
3. Freon vapor is pumped out of the evaporation compartment using a special compressor. The refrigerant undergoes an increase in temperature and changes its state to a foggy-like state.
4. Freon enters the compartment with the capacitor located in it. There the temperature of the refrigerant decreases and it turns into a liquid state.
5. Liquid freon again enters the evaporator compartment, and then the main operating cycle of the device is repeated.

In order for installation and installation to be completed correctly, before connecting the air conditioner yourself, it is recommended to understand and remember the basic principles of the air conditioner.

Basic nuances during installation

Before installing the equipment, you must also familiarize yourself with the basic requirements for proper operation:

• It is imperative to monitor the condition of the drainage pipe. It should not have additional kinks or bends. Excessive kinks are an excellent environment for the emergence of pathogenic bacteria.
• Maximum energy savings. It is worth protecting the compressor from excessive load.
• Carry out the procedure for installing the outdoor unit in the coolest place. Its additional heating ensures unnecessary electricity consumption by the device.
• During installation, it is necessary to prevent dust and dirt from entering the system.
• To save energy and reduce the load on the compressor, it is necessary to mount the indoor unit higher than the outdoor unit.
• When working, you must strive not to break the tightness of the device and prevent the appearance of cracks. Otherwise, it will cause refrigerant leakage.

Before you produce independent connection air conditioner, it is recommended to familiarize yourself with these nuances and observe them during installation.

Choosing an installation location

Before installation, you should carefully study the requirements for the split system. They are outlined in the instructions for the device.

The air conditioner does not require a specific installation location, but when choosing it you should adhere to the following criteria:

• The location of the indoor and outdoor units should be selected by calculating the minimum length of the route. If it is less than 6 m, then additional refilling of the equipment with freon will not be required. If its length is short, the formation of moisture and condensation in the device will be reduced.
• When installing the indoor unit, the distance of the unit from the ceiling should be taken into account. It must be at least 15 centimeters. The distance to the side wall should be higher than 30 centimeters.
• Air flows must circulate without obstacles, freely at a distance of at least 1.5 m.
• The outdoor unit also requires compliance with basic installation rules. It is recommended to install it either directly under the window or with right side From him.

Connecting an air conditioner with your own hands requires compliance with basic installation requirements and the right choice device locations. Only if all these requirements are met can the correct and durable operation of the split system be guaranteed.

Route length

When installing the system, you may encounter the problem of route length. It is necessary to calculate its length as accurately as possible for further maximum efficient operation of the air conditioner.

Remember that after calculating the optimal length, you should add 50 centimeters to it. In this case, you can not be afraid to carry out installation with bends, without fear of damaging the integrity of the pipes.

The optimal length should not exceed 6 meters. If during the calculations it turns out to be significantly higher, it is recommended to change the layout and perform the calculation again.

For any (both low and high) route length, a loop must be installed. It is necessary to suppress vibrations.

After calculating the length, you should purchase a kit for connecting the air conditioner. Its minimum length should be approximately 1.5 meters.

Tools

To carry out the procedure self-installation You will need the following tools:

• Pressure gauge
• Tester
• Power phase indicator
• Hammer
• Chisel for a hammer drill with a diameter of 10 cm
• Pump with vacuum system
• Hand pump
• Pipe cutting device
• Scouring
• Flaring kit.

Installation process

It is worth familiarizing yourself with the installation process of the air conditioner. It is necessary to follow the sequence of work, and it is also necessary to carry out the electrical connection of the air conditioner in compliance with basic safety rules.

Installation of the outdoor unit

It is worth noting that independent work only permissible when installed on the first and second floors of buildings. At higher altitudes, you must contact specialists. An alternative is to install an external unit on loggias or balconies of the upper floors of buildings.

Installing an external unit does not require additional skills and does not cause difficulties in operation. For optimal performance It is recommended to act in pairs.

• First you need to choose a place for the brackets, install and secure them.
• Then install outdoor unit onto the brackets and attach it.

Installation of the indoor unit

Basic steps when installing the unit indoors:

• Determining the optimal location
• Installation of electrical wiring
• Installation of communication holes
• Pipeline laying
• Connecting blocks
• Checking the system for leaks
• Establishing a vacuum inside the air conditioner
• Filling the unit with refrigerant
• Connecting the air conditioner to the mains
• Carrying out test work air conditioner
• Insulation of the harness passing between the blocks
• Closing a hole in the wall.

Before carrying out the installation procedure, you should familiarize yourself with the basic requirements:

1. It is prohibited to install the unit in places that obstruct air flow (behind curtains and drapes)
2. Installation above heating appliances is prohibited
3. Installation in rooms with a large number of electrical appliances that create interference is prohibited (for example, electrical appliances in the kitchen interfere with the operation of the air conditioner, so installing an indoor unit in this room is impractical)

Completing the installation

After completing the installation procedure, you should ensure that the device is operating correctly. To do this, you need to turn on the circuit breaker. The device will start operating in test mode. If this mode does not turn on on its own, you should turn it on using the remote control. If in this case it is impossible to enable the test mode, you should disconnect the device from the network and seek help from specialists.

If the air conditioning test system has started and was completed successfully, you should pay attention to the air flow. If cold air enters the apartment, the blinds on the indoor unit have taken the optimal position and are oscillating, then the installation of the split system was carried out correctly. You can begin standard operation of the device.

In order for the air conditioner to work as long as possible and to avoid malfunctions, you should constantly monitor the condition of the device, clean it, disinfect it and refill the freon refrigerant level in a timely manner. If there is the slightest malfunction in the operation of the system and a decrease in operating efficiency, you should disconnect the device from the network and carry out diagnostics.

That's it now more people want to buy and install a split system in their apartment. And it's not just air conditioning. The split system allows you to better freshen the indoor air. What is its advantage? First of all, it does not block natural light, since it does not cut into window frame. The second advantage is that it does not depend on common system air conditioning of the house as a whole. And lastly, it consists of only two blocks: internal and external. The only reason why a large number of consumers hesitate to purchase a split system - this is due to ignorance of the rules for its installation. Let's look at all the steps in order and tell you how to install a split system yourself.

Compound

First of all, you need to know what this air conditioning system consists of. It includes two separate units: an external one - a condenser, and an internal one - an evaporator. They communicate with each other through electrical wires and two tubes made of copper through which the refrigerant circulates. In addition, the indoor unit is equipped with a thin plastic tube that performs a drainage function, that is, it removes condensed moisture from the system. According to the rules, it must be connected to a special drain tank or to sewer pipe, but for some reason, most often it ends up being taken outside, and the water from it drips directly onto the heads or under the feet of passers-by.

Principle of operation

It is quite simple and consists in the fact that if the room needs to be cooled, then freon flows through a copper tube from the heat exchanger of the external unit to the heat exchanger of the internal one. Thus, the refrigerant is processed by the fan, and cold air comes out from inside the air conditioner.

If, on the contrary, the room needs to be heated, then the heat pump of the external condenser begins to work as an evaporator, and the evaporator, in turn, acts as a condenser. The split system is also equipped with a compressor located in external unit. Its main function is to compress freon, which significantly increases the efficiency of the air conditioner.

Mounting methods

Internal units of split systems can be either wall-mounted or floor-ceiling. The latter can be successfully attached to both the ceiling and the floor. Most often in apartments multi-storey buildings wall blocks are used. They are equipped with movable blinds, with which you can change the direction of air flow.

The power of wall-mounted units is specifically limited by the manufacturers themselves, since if the flow of cooled air is too strong in small room it can literally blow away whatever is there. If the room is quite spacious, for example, it is an office or workshop, then a more powerful split system with a floor-ceiling indoor unit is installed in it.

Installation tools

In order to install a split system with your own hands, you will need a number of accessories that you will have to purchase or rent. The quality of the work performed and the durability of your air conditioner directly depend on what tool you use during the installation process. You will need:

● Rotary hammer with a set of chisels. It is useful for making holes in the main wall.

● Rebar detector. It may be needed if the walls of the house are made of concrete. If during drilling the tool hits the reinforcement, you will have to make another hole.

● Tube flaring kit. It will not be possible to do this work efficiently using improvised means, since it will be impossible to achieve complete tightness.

● Pipe cutter. Under no circumstances should you cut off the pipes through which the refrigerant circulates with a regular hacksaw. Copper chips always remain in the gap, which can subsequently lead to compressor failure.

● Shabrovka. This tool is used to strip cut ends of pipes. An ordinary file or needle file is not suitable for this purpose precisely because of the sawdust.

● Pressure gauge. Needed to measure the refrigerant pressure in the system.

● Vacuum pump. It is necessary to process the system before filling it. Quite often you can hear advice that it can be washed with refrigerant. This is fundamentally wrong, since it does not remove moisture and spoils the compressor, just like metal chips.

● Hand bicycle pump. It is used to check the system for leaks.

● Tester and phase indicator. These devices are necessary for electrical installation work.

Tubes and working with them

Experts recommend buying in store copper tube a whole bay at once, and it doesn’t matter if there’s an extra one left. It can be used elsewhere. But if iron filings remain in the cut tube, you risk damaging the compressor of your air conditioner. Also, when purchasing it, you need to make sure that there are no visible cracks or dents on the surface, and that its ends are rolled by the manufacturer.

Before installing a split system yourself, you need to practice flaring the pipes. It is worth noting that this procedure is only done special tool and nothing else.

To practice working with flaring, you need to take the same small piece from the store along with the tube, but do not touch the coil itself. At the same time, you can try to cut the tube in a circular motion, and also scrape the product, holding it end down.

Installation

In order to produce high-quality installation split systems with your own hands, you need to know the sequence of actions. Professionals recommend installing air conditioners only before or during renovation, since you will still have to chisel the walls, lay electrical wiring and attach the brackets. If the repairs have already been made, then all communications can be hidden using external boxes, but this, as you yourself understand, will not improve the interior. How to install a split system yourself correctly will help you understand phased implementation this work.

Stage one: electrical wiring

If we take even the lowest-power modern air conditioner, which consumes 1.5 kW of electricity, then it also needs to lay separate wiring with a cross-section of at least 1.5 square meters. mm. In addition, you will need an automatic shutdown.
When connecting the wires to the input panel, you need to find where the phase and zero are located with a special indicator, and after determining, mark them at both ends.

Stage two: outdoor unit

It is strictly not recommended to install an external split system unit yourself if your apartment is not on the first floor, as there is a risk of falling from a height. But on the other hand, thanks to the presence of loggias and balconies on the upper floors, this problem practically does not exist. In addition, maintenance and repair of air conditioners in such cases become more convenient.

Typically, a split system is installed on the east or north side of the house. But even if you had to attach the outdoor unit from the south, the balcony canopy will still protect it from direct exposure to sunlight.

Stage three: indoor unit

In order for the installation of a split system with your own hands to be successful, you must strictly follow the sequence of actions. First, using screws, attach special brackets to the ceiling (if it is a floor-ceiling air conditioner) or to the wall ( wall system). Having completed this work, it is necessary to check the strength of the fastening, namely, install the indoor unit and connect it. If the structure does not wobble or vibrate, then the brackets are securely fixed.

It is easiest to install a split system with a floor-mounted unit, since it usually does not require fasteners. But you still need to finally decide on its location, because after laying communications it will no longer be possible to rearrange it.

Stage four: punching gutters

If you doubt your knowledge or are not sure about something, you can always get advice from a specialist who will tell you how to install the split system yourself and connect the freon pipes and electric wires, thereby connecting the two blocks to each other. To do this, special gutters are usually punched into the ceiling or walls, but only if it is necessary to lay a hidden pipeline.

If you don’t want to hammer, then there is another option. All wires can be covered with skirting boards or decorative plastic boxes.

If multi-storey building consists of blocks, then before you start punching a hole in the wall, you must first use a rebar detector to determine the places where the iron core lies. Under no circumstances should you cut the reinforcement, as it is located in the outer load-bearing wall. According to the standard, the hole diameter must be at least 80 mm. Sometimes you can hear recommendations about 50-60 cm, but here the thickness of the thermal insulation was clearly not taken into account.

In addition, you will definitely need an assistant to stand below and warn people passing nearby, since a piece of brick or concrete accidentally falling from a height can injure someone. Such an incident can be very costly for the owner.

Stage five: connecting pipelines

In order not to make a mistake and to correctly connect all the pipes, you need to carefully study the instructions on how to properly install a split system. First, you need to measure the required length of the tube and cut it off with a margin of at least 1 m. All excess will be used for bends.

Professionals warn that bending tubes must be done with great care, as they can break, and sometimes wrinkles form on their surface. They create obstacles to the free flow of refrigerant, which leads to a significant increase in energy consumption. The minimum permissible bending radius is 100 mm.

Then polyurethane foam hoses or flex insulation are put on the tubes. It is highly undesirable to use foam rubber. After this, threaded flanges are put on them, and the ends are flared. Next, the pipelines are connected to the fittings. The main thing in this work is not to confuse the connection. Most air conditioner manufacturers make the cold and hot fittings different in diameter.

For the drainage system you will need a piece of reinforced plastic pipe. It is connected to the waste pipe using a heat-shrinkable tube or threaded flange. The drainage must be installed at an angle of at least 5-10 mm. This is necessary for the natural flow of water.

Sometimes, for some reason, such a tilt cannot be made. In this case, you will have to additionally install a special pump to pump out moisture. I must say that purchasing it can cost about 70-200 dollars. The price depends on the pump model.

Stage six: sealing and vacuuming

The simplest and reliable way checking sealing - soap solution. To prepare it, you need to buy half a liter of distilled water at the pharmacy and heat it, then throw in shavings of laundry soap.

By using a rubber hose from a bicycle hand pump connected to the outlet nipple, you can easily check the seal quality. This is done like this: one worker pumps up the air, and the other spreads a soap solution onto the threaded connection with a brush and watches for the appearance of bubbles. When they stop swelling, tighten them another 1/8 turn. After completion of work soap scum cleans with a damp cloth.

Having completed the seal check, the system must be evacuated, i.e., moisture, dust and air that have entered there must be removed. To do this, return the nipple to its place and tighten it. Next, connect a vacuum pump and pump for about an hour. During this time, the moisture from the system should evaporate along with the remaining air.

Final stage: testing

To carry out the tests, the split system is filled with refrigerant from a cylinder through a special adapter on which a pressure gauge is installed. Wait until the pressure gauge shows the pressure indicated in the instructions. It is worth noting here that air conditioners running on freon cannot be filled with refrigerant, and vice versa.

During testing, the circuit breaker is turned on, and the air conditioner should enter the mode itself. If this does not happen, you need to try running the test using the remote control. If this does not help, you will still have to call specialists, but know that all installation guarantees have already been lost.

In the event that the test is successful, the cold air is released and the blinds are installed in the desired position, you can safely tell yourself and others that you now know how to install a split system yourself. AND finishing touch- You need to repair the hole in the wall. And not with foam, but thoroughly.

An air conditioner is a unit designed to create favorable indoor climate conditions. It is used to reduce temperature in summer period. Connecting the air conditioner to the electrical network has great importance For proper operation device elements. You can perform this procedure yourself, following the instructions and safety rules for handling electric current.

Connection methods

U household air conditioners The electrical connection diagram differs from more powerful industrial units. The latter are usually connected to three-phase network, and at home - only to single-phase. Two main methods are used electrical connection air conditioner:



In the first case, the connection is carried out as in the situation with any other electrical equipment. The disadvantage of this method is the excessive load on the outlet if the device has high power. In addition, protruding wires do not look very attractive and spoil the interior. This method is suitable for mobile and low-power units. The second method is more labor-intensive, but allows you to hide excess wires in the wall groove and connect more powerful devices.



Equipment installation

Structurally, air conditioners are produced in the form of monoblocks and split systems. The second type consists of an external (compressor-condensing) device and an internal (evaporation) device. Before installation internal structure first you have to choose appropriate place for installation. The following rules must be taken into account:

• the distance between the device body and the ceiling is at least 15-30 cm;
• between the side surface and the wall - about 30 cm;
• space for exhaust air - more than 150 cm.




For installation external structure choose a place next to a window or balcony. It can be installed on the wall inside the loggia if there is free space. On the first floor high-rise building The device can be mounted above a window, placing it out of reach of passers-by.

For installation on upper floors, it is necessary to attract installers with special equipment. During installation, it should be taken into account that the maximum permissible distance between the device blocks should be no more than 5 m.

Self-installation of air conditioning part 3



Connecting blocks together

The electrical circuit of a split system includes the installation of electrical wiring between two air conditioner units. After installation, they immediately begin to connect them together. For this purpose it is used copper wire with three cores and a cross section of 2.5 mm². It is advisable to use a cable with multi-colored cores to avoid mistakes. Otherwise, you will have to determine the required core using a tester. The algorithm of actions is as follows:

Before installing the covers, it is advisable to use a tester to ensure that the wires are connected correctly.



Socket for mobile air conditioner

To connect a mobile or low-power air conditioner, you need to purchase a three-core VVG cable with a cross-section of 2.5 mm², a three-core PVS wire of 1.5 mm², a grounded socket and a plug. If there is no free circuit breaker in the electrical panel, then you should buy one too.

From panel to electrical mounting box the cable is pulled along the groove. The socket can be installed at any convenient height. The cable is fixed with a solution in the channel, the machine is installed in the panel, the stripped copper ends of the wire are connected to it. When the solution has hardened a little, proceed to installation and connection of the socket.

Then the PVA connecting wire with a plug is assembled, and the other end is connected to the air conditioner. To do this, remove the panel and protective cover, loosen the terminal screws, insert the stripped ends of the wire one by one and tighten them securely.

The cover and panel are installed in place. To check the correctness of all connections, a test run of the unit is carried out. To do this include electric machine and air conditioning. It is advisable to check the device in all operating modes.




Attaching the cable to the electrical panel

The connection diagram for the split system to the electrical network involves the use of a three-core copper cable. If the air conditioner has a power of less than 3 kW, then its cross-section is allowed to be 1.5 mm². With a unit power of 3 to 5 kW, the wire cross-section should be 2.5 mm².

A cable marked VVG, which is protected with polyvinyl chloride insulation, is considered more reliable. Its service life is about 30 years. If you plan to lay the wire in a groove, then would be better suited flat cable VVG-P. For installation in a cable duct or in a corrugated pipe, non-flammable VVG-NG wire is used.

After installing the air conditioner, mark the line of the future groove with a pencil from the housing to the electrical panel. A channel is cut with a wall chaser. The bottom shelf should be parallel to the floor so that the cable does not fall out during installation. During installation the wire can be fixed with alabaster, as it hardens faster.

The entire channel must be sealed cement mortar or liquid gypsum with a plasticizer. The ends of the cable should have a small margin to make it easier to connect them to the air conditioner and the switchboard.

Using a Circuit Breaker

In the connection diagram of the air conditioner to the electrical network, the mandatory elements are protection (RCD) and a circuit breaker. In addition, there are differential circuit breakers that simultaneously perform the functions of an RCD and a circuit breaker.

The choice of switch is based on the available space on the electrical panel, the cost of the devices and the ease of installation. The differential switch will take up two places in the electrical panel, and the protective device and circuit breaker will take up three.

If there is not enough free space, then a differential machine is installed. It is much easier to install than protection and a machine gun. But identifying faults in electrical diagram it is more convenient if a protective device is present, since the differential machine is not able to identify the cause of the failure.

When performing repairs in the RCD system and the machine, you can replace one element, which will be much cheaper than changing a completely universal switch. If several air conditioners are installed, then the application here protective device necessary, since this device can serve several lines at once.

INSTALLING AN AIR CONDITIONER WITH YOUR HANDS

In the panel, circuit breakers are mounted on a DIN rail. It should be borne in mind that if several switches are installed nearby, their performance deteriorates due to poor cooling. In addition, as the air temperature in the room increases, the load capacity of the machines also changes for the worse. If you are not confident in the success of self-installation and connection of the device, then you should seek help from specialists.
