Installing the air conditioner installation rules. Installing an air conditioner with your own hands: we do the installation according to the instructions in the apartment. On economic feasibility

Installing an air conditioner requires experience in similar work, as well as theoretical training. In most cases, violations in the operation of this system occur due to non-compliance with the installation and connection rules.

Self-installation of air conditioning

Before installing the air conditioner, you should know the sequence of steps:

1. Selecting a location for installation.
2. Hang the indoor and then the outdoor unit.
3. Laying communications.
4. Setting up the correct operation of the system.

What do you need to install an air conditioner yourself?

In order to do all the work yourself, you need a set of tools. For installation you will need:

1. High power perforator. With its help, through holes are made that allow pipes and cables to be passed for tying the outer and indoor unit.
2. Pipe cutter. Useful for cutting copper pipes. You will also need a file, with which the burrs on the pipes are removed.
3. Pipe bender or spring to give the pipes the desired shape.
4. Drill and drills of different diameters.
5. Expander and calibrator.
6. Wall chaser, which is useful when laying a groove in the wall. It can be replaced with a hammer or a sledgehammer, but this way the work will be much more difficult and time consuming.
7. Screwdrivers, hexagons, level, hammer and other tools that may come in handy along the way.
8. Building level.

What can be useful for installing an air conditioner

In addition to tools, you will also need materials:

1. Copper seamless pipes, which are necessary for the cooling and air conditioning system. Typically, the length of the pipe is equal to the length of the route in the wall plus 30-40 cm. The diameter will depend on the requirements of the air conditioner manufacturer.
2. Electric cable - its quantity is usually indicated in the instructions for the device, but it is better to take it with a margin.
3. Drainage pipe - this will require a special or plumbing-polypropylene. Its length should be 80 cm more than the track.
4. Pipe insulation - a rubber sleeve is best suited.
5. Plastic box - you will need it to hide the track in the wall.
6. Fasteners for the outdoor unit - usually ready-made corners and brackets are bought.
7. Bolts, fasteners.

How to install air conditioning in the apartment yourself

First you need to decide on the installation location and its method. Air conditioners are installed in the apartments, the external and internal blocks of which are connected by a pipe in which there are wires and freon.

Important! Do it yourself air conditioner installation better in spring or summer.

To install correctly, you should first study the instructions. There are indicated necessary materials that will be required during the work. It is better to buy them in advance.

The sequence of actions will also be indicated there, in almost all cases they are identical:

• The location of the block, the track and all other devices are marked on the wall.

Route for system fixtures

• It is necessary to mark the places where the wiring passes in the wall. This can be done with a special device.
• Next, the plate of the indoor unit is attached. It should be horizontal (building level will help to align). Then the plate itself is applied and places for drilling holes are marked. After that, they are drilled and fasteners are inserted there.
• Then the plate is put into place and carefully fixed.
• The outdoor unit is installed in the same way.

• The evenness of the installation is checked and everything is neatly fixed.
• Using a perforator, a through hole is made through which communications will pass.

After these steps, a route is laid in the wall.

Important! The number of fasteners should be equal to the number of holes in the block. Otherwise, the structure may not support its weight.

How to install an outdoor unit

All work begins with the installation of the condenser, suitable brackets are selected that will support the weight of the air conditioner. It is better to attach them to the wall itself, and not to the insulation or cladding of the room.

Fixing the system on the facade of a high-rise building

To protect the systems from the adverse effects of the environment, it is covered with a visor.

The drain pipe from the outdoor unit must be discharged into the sewer.

How to install the indoor unit

The distance between the two units should be proportional to the capacity of the system. The smaller it is, the better the system works.

It is for this reason that the indoor unit is installed on the same wall as the outdoor unit. If this is not possible, then the closest place is chosen.

It is important to consider that:

1. Air conditioners cannot be installed above the bed.
2. The distance to the ceiling must be at least 10 cm.
3. Do not place above windows and radiators, as well as in an unventilated area.
4. Do not place the air conditioner close to furniture.

You should provide free access to the device, this will improve its performance and allow you to clean it in a timely manner.

The installation of the indoor unit is almost the same as the outdoor unit. First you need to choose a place, then attach the brackets, and on them, the evaporator. The only difference is that before installing the indoor unit, you need to drill a hole for the freon tube.

After installing the entire system, the two units are connected, and the air conditioner is connected to the network.

How to connect blocks

Air conditioner units must be connected with copper pipes (2 pieces) and cable. They can be laid on the wall and hidden in a special box, or in a strobe. In this case, you will need to make a groove. But first you need to drill a hole in the wall, which is done after installing the fasteners. Then the block connection begins, for this you will need:

1. Pipes with a larger and smaller diameter, on which thermal insulation is put on.
2. Then they are pushed through a hole in the wall and bent with a pipe bender.
3. On both sides of the pipes, special tips are put on to protect them.
4. The wire is also led into the hole and connected according to the instructions. Each block has terminal blocks to which the wires will be connected, according to their colors.
5. Then, a drain pipe is connected to the specific outlet of the indoor unit. Its second end is displayed on the street.
6. The drain must be carefully fixed to prevent it from sagging.

Connection of system blocks

If the installation of a plastic box is required, then all communications should be bundled. This can be done with zip ties or metallic tape.

How to connect the air conditioner to the mains

At the final stage of the installation, copper pipes are connected to the mains according to the scheme. With the latter, things are much simpler, at the bottom of the indoor unit there is a conclusion, and this is where the drainage is inserted.

After that, you need to connect copper pipes. You need to start work with the indoor unit. There are two ports on its side wall, one with large fittings and the other with small fittings. You can start with anyone.

The whole work process is as follows:

1. Nuts must be removed from the copper pipe connections.
2. Then the plugs are removed and the evenness of the edges is checked.
3. Union nuts are put on the pipes. It is important not to confuse the thread direction.
4. The edges of the pipes are flared and clamped in the holder.
5. The roller is installed and the screw is tightened.
6. Rolling should be completed after the cylinder stops lowering.
7. The flared edge is led to the outlet of the indoor unit and, with the help of a union nut, is connected.
8. The external unit is connected in the same way.

Connecting the air conditioner to the mains with your own hands

The wiring diagram for connecting an air conditioner at home can only be single-phase. This can be done through an outlet or using a wire leading to an electrical panel.

With socket

First, lay the cable from the evaporator to the outdoor unit. For this:

• A wire is laid to connect the blocks.
• A line is drawn to the electrical panel. This includes a cable and an overload protector.
• If the devices have an average power, then they can be connected without such a line. This is done directly to the outlet.

Important! The air conditioner can operate at different capacities, so the circuit breaker should be installed on the connection line and near the outlet.

How to choose an outlet

It must meet the following requirements:

• Have reliable grounding.
• Comply with the specifications of the air conditioner manufacturer.
• All wires must be copper.
• The socket must be connected to the shield through a circuit breaker.

Socket for air conditioning system

With separate cable

This method is considered the most reliable and safe, especially if you install a trip protection device that will protect the system from power surges.

Requirements for this connection:

1. Mandatory presence of a device or automatic shutdown protection.
2. All components must be copper.
3. The diameter of the wires must correspond to the size specified by the manufacturer.
4. A separate ground must be created for the entire line.

Then all cables are laid, and the operation of all components of the system is checked.

Height from air conditioner to ceiling

The most optimal height at which the air conditioner is hung is 10 cm from the ceiling. This will provide the correct flow of cold air that will pass over the top. At the same time, there will be enough space for air circulation. However, for more powerful air conditioners, this distance can be increased by 5-10 cm.

The distance is calculated from the plinth

How to install a mobile air conditioner

A mobile air conditioner is much easier to install than any other. But even here some skills are required. You also need the following set of tools:

1. Dense plastic (thickness 10-12 mm). It will be required to create a barrier between the cool air in the room and the warm outside.
2. Saw for plastic.
3. Masking tape or tape with which the sheet is fixed.
4. Mounting foam or any sealant that will provide water and air tightness.

Mobile device installation option

It is best to place a mobile air conditioner near a window, while avoiding fractures on the air outlet hose. The installation sequence is as follows:

1. All necessary measurements and the diameter of the air outlet are made.
2. Cut a hole for it. It should be 3-4 cm smaller than the pipe itself. This will help keep it firmly in place.
3. Plexiglas is sealed. This can be done with adhesive tape, sealant or polyurethane foam.
4. Need to open window frame and fix the plexiglass insert there. This can be done using the same tape or sealant.
5. After that, you can install the monoblock itself. To do this, a place for its installation is selected, a drainage hose is inserted into the air outlet, and it is inserted into the exhaust port of the monoblock. The other end of the hose goes outside.
6. You can in 2-3 hours.

Installing an air conditioner without a vacuum pump

If the length of the route is less than 5 meters, then the air conditioner can be installed without a vacuum pump. This will require:

1. Unscrew all plugs on the ports.
2. Next, a hex key is taken, which is selected according to the size of the lower port.
3. Next, the key is inserted into the port and scrolled 90 degrees. At this time, freon comes out, which, together with air and freon, creates excess pressure.
4. There is a spool on the port, which is compressed for a while. At this time, a mixture of gases will come out, which will carry out air and argon.
5. Then we repeat the previous steps. If the track is 4 meters, then this will be enough, if 3, then you should repeat it again.
6. A plug is screwed onto the outlet with a spool.
7. With the help of a hexagon, the lower and upper ports are opened, where freon is admitted.
8. The system is ready to go.

Installation of air conditioning on high floors

Installation of air conditioning on the upper floors of the house can be done on the roof. The distance between the blocks will be approximately 15-20 meters. This can be done with a crane and a sliding ladder.

If this option is not suitable, then the system can be installed on a balcony or under a canopy. In this case, the following points must be taken into account:

1. The walls where the system is installed must be strong and able to withstand a lot of weight.
2. Do not install on aerated concrete walls.
3. Do not attach the system to a ventilated façade as this will cause noise and vibration.
4. Everything should be installed evenly and without distortion.
5. The distance between the outdoor unit and the wall should be at least 10 cm.
6. Do not install an air conditioner on a glazed balcony, as this will impair its performance.
7. Be sure to install a visor above the outdoor unit, which will preserve the integrity of the system.

Requirements for installing air conditioners

In order for the air conditioner to bring maximum benefit, you must follow some rules:

1. Choose exactly the model that matches the parameters of the room (size, availability of equipment, etc.).
2. Correct installation.
3. Compliance with the rules of operation and prevention.

The air conditioner has two blocks, each of which has certain functions. The outer one is the condenser and the inner one is the evaporator. They are connected using wires, tubes in which freon functions.

It is very important to choose the right place to install the system. In this case, the weight of the block, free access to it, and so on should be taken into account.

Install the air conditioner closer to the window

The outdoor unit must be located on a solid wall that can support a weight of more than 60 kg. Do not install on aerated concrete. The outdoor unit must be protected from the environment. This can be done with the help of fences and canopies.

When installing the indoor unit, consider:

1. The distance from the outdoor unit to the indoor unit should be as short as possible. This will provide higher efficiency.
2. The evaporator must not be obscured by curtains, furniture, etc.
3. There must be a distance of at least 3 meters between the furniture and the indoor unit.
4. The system must not be installed above batteries.
5. Provide free access.
6. The distance from the block to the ceiling must be at least 10 cm.

It is necessary to ensure the tightness and reliability of fastening the air conditioner. If a line is used to connect the blocks, then the connections will need to be evacuated.

What is the maximum length of the air conditioner route

As already known, the larger the track, the lower the power of the entire system. The passport for the air conditioner indicates the maximum distance of the route. Typically the vertical distance is 7 meters and the horizontal distance is 15 meters.

How to hide the air conditioner in the interior

Usually, the air conditioner is installed during repairs, so it is better to choose an option that will fit into the interior without a win. If this fails, you can try:

1. Paint the air conditioner the same color as the wall.
2. Place it above the front door.
3. Buy a built-in split system that can be hidden in a stretch ceiling.
4. The floor air conditioner can be hidden in decorative panels.
5. Place the air conditioner in a shelf or cabinet in which free air circulation will be ensured.
6. You can make a niche for the block.

In this case, everyone decides which option will be more convenient. In any case, it is not worth cluttering up the passage to the fan, as this can lead to overheating and a quick breakdown.

You can hide the air conditioner under the ceiling

In the hot season, air conditioning is a must. It is very important to install it correctly, otherwise the whole system will not be able to function and will quickly fail. If you do the installation yourself, then you should follow all the rules, and before that, study the manufacturer's installation instructions. This will help you quickly and easily do all the work.

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 each owner of this device.

Installation instructions

Installation instructions for split systems include the following items:

1. Choosing a location for the system.
2. Air conditioner installation.
3. Installation of 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 mount the device on their own on site, and subsequently engage in its maintenance, all this is possible, even if before that you had no skills and did not encounter this equipment. It's just worth considering one factor when you install and configure a new system yourself, keep in mind that the store's warranty will no longer apply to such equipment.

Selecting a location for the system

The air conditioning system must be located in a place that will not be cluttered up later. Air intakes and air distribution openings must be fully accessible.

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

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

The rules for installing split systems completely exclude direct sunlight from entering the indoor unit of the device. The condenser grid itself must be completely protected from direct rays. If the installed outdoor unit will be located on the roof, then its front side should be turned to the shady side.

It is necessary to provide for the conditions for the device drainage system, through which the condensate formed during the operation of the unit will be discharged to the outdoor unit.

The plastic most commonly used for the indoor unit is very sensitive to known fluorescent lamps, so it is desirable to install the device in a location that is far away from them.

And one more important condition. The inner compartment must be at least 1 meter from microwave oven, since the radiation emitted by the microwave during operation adversely affects the operation of the installation and causes interference.

Selecting a location for the outdoor unit

When installing the outer compartment, the most important thing is a strong mount. The wall must be flat, the mountings in the form of special brackets must be installed in such a way as to dampen the vibration that occurs during the operation of the device as much as possible.

It is necessary to carry out the installation of 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 forced by anything.

Air conditioner installation

Before proceeding with the installation of the air conditioner, you need to take care of the availability of the necessary funds. You will need the following tool for installing split systems:

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

Installation of the device includes the following operations:

1. Initially, you should open the front panel and unscrew the screws from the cover that closes the electrical box, it must be pulled out.
2. Connected to the installation electrical cable and the cover is put in place. 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 a ground connection.

Installation of the drainage system

The drain hose must run under the connection pipe. It should not twist or bend. In the future, the hose must be wrapped with heat-insulating materials. Where the drainage route runs close to the wall, it is desirable to lay inserts of heat-insulating material. And the track itself is usually wrapped with felt tape.

Be sure to check the reliability of the connection 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.

Experts are advised to adhere to the following restrictions when connecting a pipe line. From the inside, the number of possible bends in the route should not exceed 10 in total. The radius of the most possible bend should not exceed 10 cm.

The cap on 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. Oil must be applied to the joint.

Hole tightness

Independent installation of a split system must be accompanied by careful sealing of all docking holes. It all starts with sealing the hole in the wall. For this, the usual standard putty is suitable.

The drainage pipe is usually tightly fixed with a special clamp. With regard to the electrical connection and the cable connecting the units for data transmission, they must be connected in accordance with a special diagram. Usually it is attached to the device passport. Depending on the type of installation and the manufacturer, the connection must also be made.

The cable and data line are connected to the appropriate terminals, which are usually marked different color. The cables connecting the two units must also be secured with 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, then the risk of injury increases. electric shock or elementary fire, since dust, dirt or water can easily get inside.
• The electrical connection cable must under no circumstances be connected to the cold pipe. The cable through which the freon passes heats up during the operation of the installation, so their contact should be excluded.

How to bleed air

Do-it-yourself installation of a split system implies that you will also have to bring the system itself into working condition with your own hands. Initially, you need to get rid of the airiness of the system. To do this, you need to bleed 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, it is necessary to turn the gas valve by 90 degrees with an ordinary hexagon. counterclock-wise. After counting about 10 s. turn back and close it. Then apply a normal soapy solution to check for gaseous leaks.
3. If you did not find any leaks, repeat the procedure again, but after 10 seconds do not close it back, but press the fitting for service work. Steam should come out, indicating that air has begun to escape from the system.

Extra Freon charge

The maximum length of the connecting hoses through which freon moves must not exceed 7 meters. But in the case when another installation of the system is impossible for one reason or another, it is necessary to increase the length of the route for the refrigerant. In this case, a mandatory refueling of freon into the system will be required.

When all the work has been completed and, if necessary, additional refilling of freon into the system has been made, the next step will be the need to make a trial run of the installation.

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

In order not to languish in the heat in the summer, and to heat the rooms in the cold period, you planned to purchase a split system. Moreover, you want to install and connect it yourself in order to save on professional installation (which is not always the case).

Our publication has 2 tasks: to tell how to properly install an air conditioner with your own hands and to analyze how economically feasible it is. Let's go in reverse order and first compare the costs for our own and custom installation, and for this we list ...

Mounting tools and materials

We will not disclose here the principle of operation of a split system, it is described in detail on our resource. For a general understanding: between two heat exchangers - external and internal, a refrigerant (freon) moves through pipelines in a liquid and gaseous state, transferring thermal energy to the street or to the house, depending on the selected mode (air conditioning or heating).

The task of the installer is to place and fix the blocks in accordance with all the rules, connect them with pipes and connect them to the mains, and at the end to start and check the units.

It also makes no sense to list every screwdriver or key; a skilled owner should have such tools at hand. Let's take into account only the equipment and accessories, without which it is unrealistic to mount and start the air conditioner yourself:

• perforator with a diamond drill or crown drill (depending on the material of the walls) with a diameter of at least 45 mm;
• Vacuum pump;
• manometric manifold.

Note. If work is being carried out in the process of repairing an apartment, then add a grinder with a circle on concrete to this list. It is useful for performing hidden laying of highways in the furrows of the walls (colloquially - strobes).

Specialists in refrigeration machines those involved in the installation climatic equipment, they will immediately ask: where is the kit for cutting and expanding copper pipes with a scraper for stripping (reamer)? The answer is simple: a beginner does not need these devices for a one-time installation of a split system with a power of up to 3 kW. It is easier to buy a ready-made installation kit, which includes all the necessary elements:

• 2 custom length copper tubes 6.35 mm (¼”) and 9.52 mm (3/8”) with correctly flared ends and nuts fitted;
• rubber insulation type K-Flex (already stretched on the highway);
• corrugated hose for drainage;
• electric cable for 4 or 5 cores with a cross section of 1.5 mm²;
• bracket for mounting the outdoor unit.

Why is it better to use a kit to install an air conditioner in an apartment? Firstly, its price is comparable to the cost of rolling fixtures and materials purchased separately. Secondly, the ends of the highways are cut on the machine, and not by hand, which contributes to a reliable connection. Poor manual flaring is the mistake of most inexperienced craftsmen, leading to freon leaks and compressor failure.

Factory (left) and manual rolling (right)

Note. Depending on the conditions for laying communications, you will have to purchase a plastic cable channel, PVC winding tape, mounting foam and a visor.

On economic feasibility

For a correct comparison, we will take as a basis the cost of installing a household split system with a power of up to 3.5 kW (7000-9000 BTU). This includes installation and connection of the outdoor and indoor module with the laying of the bundle (2 lines, cable and drainage) up to 5 m long through the wall. The price includes all related materials listed above.

In Moscow, the installation of low-power home air conditioners costs from 5,500 to 8,000 rubles, which in dollar terms is 98-143 USD. e. In other cities of the Federation, the cost may differ downwards, but the proportions are still preserved. Now we list the average Moscow prices for the purchase of materials and the rental of equipment for self-assembly:

• Makita puncher - about 500 rubles. per day;
• two-stage pump for evacuation together with a manometric manifold - 700 rubles per day;
• installation kit with communications 5 m long - 2500 rubles.

For reference. When renting equipment, it is often required to pay a deposit in the amount of 4-8 thousand rubles in relation to the specified units. Those who wish to roll copper pipelines on their own can rent sets of tools for 300-500 rubles. per day.

Adding these amounts, we get 3700 rubles. or 66 at. e. If you add here 10% for the purchase Supplies and unforeseen costs, it will come out to about 4,000 rubles (71 USD). This means that a do-it-yourself air conditioner installation saves from 1,500 to 4,000 rubles. As a rule, the lowest price threshold declared on the Internet does not correspond to reality, since it does not include part of the work and you will have to pay extra for them.

Hence the conclusion: self-installation of split systems is cost-effective and allows you to save 2500-3500 rubles on low-power units. or 45-62 at. e. One condition: the work must be done with high quality, otherwise the cost of alterations or repairs will make you remember the proverb about how many times the miser pays.

Note. Prices in rubles are taken for the period March - April 2017 and may vary depending on the exchange rate and seasonality.

How to install a cooler - instructions

The split system is mounted in several stages:

1. Decide where to hang the outdoor and indoor unit. Mark the route for laying the harness with communications.
2. Drill through the wall and lay the lines. Fix the indoor unit and connect the refrigerant pipes, wiring and drain to it.
3. Put the outdoor unit, connect all communications to it.
4. Perform commissioning.

It is important to follow this sequence of operations. You can not first mount the base plate of the indoor module, and then drill a hole for the harness, because when drilling, you can stumble on the armature, which is why the tool will lead to the side or up. In the first case, the route will look clumsy, and in the second case, you will not meet the requirements for the slope of the pipelines and the plate will have to be rearranged higher.

1. The indoor unit of the air conditioner must be hung in such a way that the air flow does not blow directly on you, otherwise a cold is guaranteed. The optimal location is directly on the outer wall or on the side partition near the window.
2. The minimum distance from the ceiling to the climate unit is 100 mm, but it is better to retreat 30 cm. A minimum clearance of 125 mm is needed between the body and the side wall in order to have enough space for curtains.
3. The outdoor unit must be installed in such a way that it can be safely serviced at height. Most comfortable spot- on the wall within the unglazed loggia or balcony. In their absence, the unit must be placed under the window so that the master can reach the service ports and all the details of the device - the compressor, heat exchanger, and so on.
4. The distance from building structures to the rear wall of the outdoor module is 20 cm, to the sidewall - 300 mm, as shown in the diagram.
5. According to the rules, highways are laid with a slope towards the street. There should be no stagnant sections in the form of loops facing up or down along the way.

Advice. Putting the outdoor module on the wall to the side of the window is wrong. Although you can reach the service ports, you will not be able to disassemble the unit without completely dismantling it. The master who came to repair the compressor has every right to refuse to perform work of increased danger (at height).

Installing the indoor unit

First of all, we advise you to unpack the product, get the instruction manual and carefully study it. The fact is that the diagram given in the technical data sheet shows exactly how to properly install and connect a split system of this particular model. Immediately remove the wall plate from the housing. Next, the procedure is as follows:

1. Drill through the outer wall so that the channel slopes towards the street. Optimum diameter holes - 50 mm. It is highly desirable to put a special plastic sleeve in it.
2. Unpack the installation kit and immediately wrap the ends of the freon tubes so that dust and moisture do not get into them. Connect the second ends to the communications nested in the niche on the rear wall of the room unit.
3. Strip the ends of the electrical cable, run it through the rear opening of the case and connect it to the terminals, drawing a small diagram on paper in order to remember the colors.
4. Form a bundle from the lines and cable as shown in the diagram below, then carefully wrap with PVC tape. Do not twist the pipes together!
5. Now precisely place the mounting plate of the unit and attach it to the partition with dowels, strictly observing the horizontal.
6. Together with an assistant, insert the tourniquet into the hole, while installing the indoor module on the plate (it is fixed with latches).

Interblock communications in a bundle

Advice. If you decide to install a split in the process of repairing a home, then it is better to lay the inter-unit communications hidden, cutting furrows along the route in the walls. Do the same with the power supply cable. How to do it yourself is described in the following video:

What you need to know for successful installation and connection of communications indoors. First, when twisting the refrigerant lines, rotate the union nut while holding the counterpart with a wrench, and not vice versa, as is done in the photo. Otherwise, “turn your head” to the factory tube and you will have to solder it. Also, do not tighten the nut with great force, so as not to squeeze out the rolling, which will subsequently cause a freon leak.

The second nuance: fasten the plate clearly according to the level, the built-in condensate tray is already made with the desired slope. And the last thing: do not plug the power cable into the socket, it looks ugly. Concealedly bring a separate line with your machine from the switchboard.

Since the article a priori cannot contain all the details, otherwise it risks turning into a story, we advise you to watch the installation video, shot by an experienced master:

We put the outdoor module

When installing an outdoor air conditioner unit in an apartment, it is important to be careful and protect yourself with insurance. Have a helper hold you by the belt while you are busy with fasteners, or use safety equipment. The installation technology is simple and step by step looks like this:

1. Using the building level, mark the drilling points on the wall and make holes for the anchors.
2. Insert the mounting bolts of the outdoor unit into the brackets with their heads down, having calculated its position on the site. Fix them with special plastic washers so that they do not fall out.
3. Install the brackets by securing them with anchors. Place the outdoor unit on them, aligning the holes with the bolts. Using a spanner wrench with extension, screw on the fixing nuts and tighten them.
4. Lead to the communication unit - screw the tubes to the ports, and connect the cable to the terminals.

Advice. Do not rush to immediately mount the visor, it will prevent you from working with service ports during the startup process. How the installation of the outer part of the split system is performed is shown in the video:

The final stage is the launch of the system

All new air conditioners from the factory are filled with freon contained in the outdoor unit. Your task is to fill the entire circuit without loss and start the split system. The order of work is as follows:

1. Connect the end hose of the gauge manifold to the service port spool on the gas side (larger diameter tubing will fit). Connect the middle hose to the vacuum pump. In this case, all valves must be closed.
2. Switch on the pump unit and open the manifold valves. During the first 10-20 seconds of operation, bleed air through the fitting provided on the pump.
3. Vacuum the system for at least 20 minutes if the length of the route does not exceed 5 m. The goal is to completely remove moisture from the circuit and pump out air, which will be informed by the pressure gauge on the manifold (it will show a pressure of minus 1 bar).
4. After half an hour, close the valve and stop the vacuum, then wait at least 20 minutes, watching the pressure gauge needle. If it begins to rise to zero, then your system is leaky and needs to be redone.
5. Using a hex wrench, turn off the service port valve on the liquid side, and then on the gas side, thereby filling the circuit with refrigerant.
6. Turn on the air conditioner and check its operation. When the pressure in the system rises, quickly unscrew the hose from the manifold and replace all plugs.

Attention! If you use an adapter for R410 freon to connect pressure gauges to the port, then to disconnect, unscrew the nut of the adapter itself, and not the hose! Otherwise, all the freon will go into the atmosphere.

When finished, let the air conditioner run in all modes and make sure that the condensate flows from the drain, and not elsewhere (for example, along the wall under the indoor unit). You can get more information about the installation of the street block and the launch of the split by watching the latest video:

Suppose you accidentally released the factory refrigerant into the atmosphere, or the gas escaped through a poor-quality connection. Eliminate the cause of the leak, buy freon in a cylinder and refill the air conditioner using.

It is unnecessary to write hackneyed phrases about the complexity of installing an air conditioner on your own, this is clear from all of the above. For a better understanding, we advise you to carefully watch the videos from different masters, and also read the comments left under these videos on YouTube. Intelligent installers often unsubscribe there and you can get a lot of useful information from them.

The last point - do not try to save on the tool. If you can take a puncher from a neighbor, then you are unlikely to find a vacuum pump for free, and you cannot work without it. Although some unfortunate installers do without evacuation, squeezing air out of the circuit with freon. But moisture remains, and then it disables the compressor.

Installing an air conditioner is not an easy task, but it is doable! At each stage, many questions arise. This is complicated by the fact that it is impossible to give one standard scheme - each case is individual. If you don’t know where to start the installation, in what sequence to perform the operations, then this article is for you!

After that, you can fit the indoor unit to the fixed plate (but do not snap the bottom clips to the plate!). Mark the bottom corners of the body with a pencil. Then remove the block from the plate.

1. We mark where the hole in the outer wall will be.

Carefully cut through the wallpaper and beat off the plaster at the drilling point. If the installation is direct or as in the photo above, then you need to make the so-called "entry" to the hole (where the tubes will go into the wall). So that in this place the bend of the "route" is smooth.

• for brick or concrete walls you will need a large hammer drill and a drill with a pobedite tip. Drill the first 2-3 cm of the wall without tilting (in a straight line) so that the drill enters the wall a little. Then be sure to tilt down. During this operation, it is better to use industrial vacuum cleaner.
• wooden wall it is better to drill with a drill with a pen drill with a diameter of 45 mm. The process will go slowly but surely. Do not forget about the downward slope of the hole.
• it is better to drill a metal profile or “sandwich” with a 45mm bimetallic crown. Also, do not forget about the downward slope of the hole.

1. If the “route” of the air conditioner needs to be pulled through just one hole in the wall, then you can proceed as follows:

We conveniently position the indoor unit and connect materials to it:

• . Open the front cover of the case and find the pads. We drag the cable through the back of the case. We write down the terminal numbers and the colors of the cores that are connected to them;
  
• unscrew the nuts (or plugs) of the tubes with two keys. Usually, air is released at the same time - we are not afraid and make sure that the plug does not fly off anywhere! Further you will need a device such as rolling.
  We roll and connect the tubes, having previously studied how this is done.
  Experience is needed to tighten the nuts with high quality (if you don’t reach them, the freon will “leave”, if you overtighten, you can break the thread). To do this, someone uses a special torque wrench;
  
• we tightly connect the drain hose to the indoor unit;
• if there is an additional wire in the kit for the air conditioner, then we connect it to the intended terminal (you will see it).

1. When the tubes are still without thermoflex, we can gently bend them under the hole (if the “installation is straight”). For "side mounting" we cut out the cap of the case.
   
2. We put thermoflex on both tubes. All tubes (including their nut connection) must be hermetically wrapped in thermoflex so that condensation does not form on the tubes. For fixing it is better to use special tape.
   
3. We compactly lay the “route” inside the block and fix it with tape. Do not forget about the "power" cable (we bring it out where you need it). Also make sure the drain hose is at the bottom.
   

In one compact tourniquet we form the following materials:

1. With the help of a partner, we drag the indoor unit with the “route” through the hole in the wall. We hang it on the plate, but do not snap the lower clips!
   
2. We bring the power cable to the right place inside the room (but do not connect it!). If required, we close the "route" inside the room with a cable channel. Fasten the lower clips of the block.
   
3. We throw the external unit on the brackets and fasten it securely. The "track" from the outside is carefully brought to the taps of the external unit.
   
4. We unscrew the nuts of the taps of the external unit (see that nothing gets into the open fittings). We put the nuts on the tubes, after which we roll them. We fasten the copper pipes to the fittings.
   
5. We connect the interconnect cable in the same way as to the indoor unit. If an additional wire is included with the air conditioner, then we connect it to the appropriate block. We connect the “power” cable if, according to the diagram, it goes to the external unit.
   
6. Further pressure gauges and a vacuum pump are required(pressure gauges must match the type of freon). Be careful here:

• we connect the LEFT hose of the pressure gauge to the fitting of the outdoor unit (to which a large diameter tube fits). We connect the MIDDLE hose of the pressure gauge to the vacuum pump;
  
• start the pump and open the LEFT valve on the pressure gauge (counterclockwise);

installing an air conditioner with your own handsClimatic equipment is installed in advance, before the onset of heat. In some cases, to save financial resources do-it-yourself air conditioning installation. The main condition is to strictly adhere to the instructions, to carry out work in the recommended place. Incorrectly selected parts can cause damage to the climate control device.

The principle of operation of the air conditioner, split system

To form a general idea of ​​the organization internal device, and before installing the air conditioner, we recommend that you consider the principle of operation of the system. Climatic consists of 2 equivalent blocks - compressor and evaporator. They are connected to each other by special adapters, branch pipes and tubes.

The evaporation unit is installed inside the dwelling, and the compressor unit is installed outside. High-performance and expensive models are equipped with one compressor and several indoor units.

Refrigerant under high pressure is sent to the evaporator. Then there is an expansion of freon, its gradual boiling and vaporization. It is this cold vapor that absorbs the heat of the air. The air conditioning system works with the active formation of water condensate, which settles on a special radiator. At the final stage, water is discharged from the building through a special tube.

In the process of operation, the compressor pumps out the evaporation of freon. The pressure inside the unit is increased by a built-in pump. Gradually, under the influence of temperature, the refrigerant changes from a liquid state to a vapor state. A dense "fog" is sent to the condensate chamber for gradual cooling (a small fan is used for this purpose) and transition to a liquid state. Then the circle closes and the process loops.

The efficiency and duration of the operation of the house, as well as the amount of electricity consumed by the appliance, are determined by the intensity of operation of the unit, the climatic features of the region. If there is a heater in the room near the climate control device, the level of electricity consumed increases, which is fraught with the failure of the device. Even ordinary dust can provoke a breakdown. The room is scheduled for regular wet cleaning.

Couplings and joints require sealing without fail in order to level the likelihood of freon or other refrigerant evaporation. Install the outdoor unit of the air conditioner so that it is level below the inside of the unit. The outdoor unit is located in a dark place, away from sun rays.

Do-it-yourself air conditioning installation: tools - a complete list

Installation of air conditioning systems is a technically complex, responsible, and therefore expensive event. All aspects are important in this matter - experience, practical skills, theoretical base and availability necessary tool. These factors determine the speed and quality of installation. Let's analyze the feasibility of using the tools that come with the standard installation kit.

Taking into account the scope of their application, they are divided into several functional groups.

power tool

Without a power tool, installing an air conditioner with your own hands is simply impossible. We are not talking about any specialized solutions:

• perforator;
• "Bulgarian";
• drill.

A powerful puncher is chosen so that it can easily make a through hole in the wall through which a line is laid between the indoor and outdoor units. Low-power combined electric drills, where only the function of a hammer drill is provided, are indispensable in this case. They are not able to drill through brickwork.

Before you install the air conditioner yourself, you should make sure that you have all the necessary tools.

For concrete wall in addition, you will need a grinder to remove metal fittings, as well as other consumables - discs, drills, concrete bits.

Measuring tool

Installation of a window air conditioner is carried out with the obligatory control of the horizontal level. You can use markers, marking pencils, building or laser level. You will also need a number of additional equipment. Air conditioners with installation cannot be reliably and efficiently fixed without additional technical means.

Specialized equipment

Specialized tools are necessary for the high-quality and efficient functioning of climate equipment. Copper pipe soldering tools, industrial type vacuum cleaner and vacuum pump.

1. Devices for connecting copper pipes. We are talking about low temperature welding. It is carried out using a special solder and a gas burner. A pipe cutter is used to cut them. It is better to refuse an ordinary hacksaw for cutting metal, since small chips will certainly remain in the line, which is fraught with damage to the climate device. To remove the chamfer, use a rimmer, rolling. The main turns are formed by a pipe bender.
2. An industrial vacuum cleaner is used to suck up dust and small debris. Under no circumstances should they fall into the appliance.
3. Vacuum pump. The unit dries up the line. If you follow the installation rules, then this procedure is mandatory, without it the efficiency of the air conditioner will be nominal.

The listed equipment for installation is basic. You can not do without additional consumables - pliers, drywall, stepladders, metal scissors, screwdrivers. The exact list is determined by the owner, taking into account specific conditions.

Do-it-yourself air conditioner installation: step by step instructions

Do-it-yourself installation of an air conditioner begins only after purchase and preparation necessary equipment, tools and climatic equipment. First of all, the outdoor unit is fixed on the outer wall, after which internal work is carried out.

At all stages, it is extremely important to observe safety precautions, especially when it comes to skyscrapers. Installation of the outdoor unit is one of the most important and crucial stages.

Outdoor unit fixing

Installation of a window in general, and its outer part, in particular, on the walls country houses is not accompanied by any difficulties. But in the case of multi-apartment buildings, not everything is so simple, the place is selected with great care. When deciding where to install the air conditioner, pay attention to areas with minimal natural light.

There are several basic rules:

1. The outdoor unit should not spoil the view from the window to the neighbors in the apartment.
2. A small tube is used to drain condensate.
3. The climatic device is placed in such a way that it is within reach, because. equipment requires periodic maintenance.

In 90% of cases, the block is fixed at the north or east side, under the window or at the bottom of the balcony. These are the unwritten rules for installing an air conditioner, which are mandatory among professionals. If they are observed, it will not be difficult to reach the outside of the climate control device.

• The attachment points of the brackets are checked with a building level, and then holes are prepared in the wall. Anchor bolts are used for secure fixation.
• To connect the functional blocks, an 80 mm through hole is made. If possible, it is better to drill a hole between the bricks, along the seam.

According to the previously prepared markings, metal brackets are installed, screwing the bolts as securely as possible. The standard installation of the air conditioner is carried out in such a way that between the climate unit and outer wall a distance of 10 cm was maintained. The gaps are closed at the final stage, after connecting the device.

Installing the indoor unit

Do-it-yourself air conditioning installation indoors, where to start? First of all, it is necessary to pay attention to the fact that it is strictly forbidden to mount the indoor unit behind curtains, near electrical appliances, above heaters or batteries - all these devices often cause failure of the block processor.

Before installing the air conditioner, you should carefully check the wall for laying heating, water pipes, and electrical wiring in it.

The fastening of a metal plate from standard components for the installation of air conditioners begins only if the area for work is completely free: the distance from the ceiling is from 10 cm, from the corner of the walls - at least 5 cm. Two points are connected with a meter and marked horizontal line. The indoor unit is mounted on a fixed metal plate.

The next step in the installation of the air conditioner, or to be more precise, its indoor unit, is the preparation of holes in the wall for connecting communication hoses, electrical wiring, and pipes for draining liquid condensate. The interior space should be sufficient for free placement of all elements in the wall.

Independent installation of the air conditioner is not possible without separate wiring for the indoor unit. For this, wiring with a cross section of at least 1.5 square meters is suitable. mm. It is mandatory to connect a separate machine for the climate control device. Upon completion of the wiring, it is connected to the input of the shield (the indicator can accurately determine the "phase" and "neutral" wire).

The terminals of the outdoor and indoor units are connected to each other with multi-core wiring (it is pushed into the hole prepared in the wall). The installation scheme is clearly described in the instructions that come with each climate control device. At self installation air conditioners at home, it is extremely important that the terminals by name match the wires themselves. Otherwise, there is a danger of a short circuit.

Pipe laying instructions

A standard air conditioner installation kit includes several copper pipes. They are carefully cut with a margin of 1 meter for bends. The tubes are prepared with a special tool - a pipe bender, when using it, the metal does not crack, no dents form. Proper preparation includes the coating of pipes with polyurethane foam hoses, which act as thermal insulation.

Special threaded flanges are put on the ends of the tube. Next stage installation work– high-quality flaring of copper tubes. This process is carried out extremely carefully in order to eliminate the risk of grooves and microcracks. The nut should fit onto the rolling without any problems. As for tightening, it is performed with a special torque wrench.

Do-it-yourself installation of the air conditioner continues: pipelines are attached to the fittings. It is impossible to confuse anything, because. copper pipes have different cross-sections and diameters. The flanges are securely screwed onto the fittings, while the connection must be extremely tight, but at the same time, the tube should not be pinched or damaged.

At the final stage, the installation of air conditioning systems comes down to connecting a plastic pipe to a reinforced housing. For reliable fastening, use a heat-shrinkable tube from the delivery set. It is better to put a drainage tube at a maximum distance from the base of the wall.

Installation and installation of air conditioners will be incomplete without placing pipes in a special hole made in the wall. There they are carefully and extremely accurately aligned. Outside, the outlet and underwater pipes are fixed with clamps for greater reliability. An electrical wire is placed near them for connection to the outdoor unit.

Holes are blown indoors mounting foam, as an alternative - filled with liquid silicone. Installing an air conditioner on a balcony and in a house involves checking the structure for leaks with a soap solution or a bicycle pump. Soap solution is washed with a sponge or cloth. If defects are found, the thread is tightened tighter.

Vacuuming the air exchange system

The correct installation of the air conditioner with your own hands is described above. The owner should know that to remove moisture, dust and the smallest particles from the climate device, the system is evacuated. It is performed upon completion of the final and high-quality sealing of the joints, because it is impossible to get rid of the air completely. The air conditioner with the installation is connected to a vacuum pump, air pumping takes about 1 hour.

Freon or other refrigerant is pumped into the system. The tank on the balcony is filled with a pressure gauge or adapter connected, since it is necessary to strictly control the pressure in the system. After preparing the air conditioner, a special automatic disconnector turns on independently, and the system goes into test mode. With uniform and efficient air circulation, the hole in the wall is sealed with mounting foam, followed by decor.

Installation of industrial air conditioners is carried out exclusively by professionals, because it's costly climatic complexes which require specialized equipment to set up. Spare parts are included in the standard package, you do not have to buy anything in addition.

Now you know how to install the air conditioner yourself and in what sequence to perform the corresponding work.

Installing an air conditioner with your own hands: the secrets of professionals

The scheme of installation of window air conditioners provides for the possibility of installation in winter period. That's just have to be content with not too comfortable conditions. Water or snow must not get into the line. It is better to install and pump in the refrigerant at positive temperatures outside the window (at sub-zero temperatures, the stuffing box often fails, since it is rubber).

To install air conditioners, it is not at all necessary to evacuate the system. The nut is not completely screwed to the copper tube, then the control valve located at the thick tube opens slightly. Under pressure, the air will be forced out by freon, and it will be necessary to quickly tighten the nut.

This method is incorrect, since the quality and sealing of the system cannot be verified. Installation of industrial air conditioners using this technology is not carried out.

Below is detailed video instructions, which demonstrate the main stages of installing climate systems with your own hands.
