Installing the route for the air conditioner

Installing the route for the air conditioner

Installation of a split system is the most important stage on the way to comfortable operation of the air conditioner. Not only the ease of use, but also the reliability of the entire air conditioning system, as well as its service life, largely depends on the correct installation.

During the installation, the communication tab is made. It is important to properly lay the route for the split system, taking into account all the nuances and features. This process looks simple and clear only in words, but in practice it turns out that such work is fraught with many difficulties.

Laying a route for an air conditioner will require a lot of effort and highly specialized knowledge from you. If you are a novice master, read this article. In it, we tell you how to lay a route for a split system yourself.

If you are not confident in your abilities, entrust this work to a professional. He has not only the necessary tools, but also invaluable experience.

General information

laying of the route

The installation of the air conditioner is carried out in several stages. The first and, concurrently, the most important stage is the installation of the air conditioner route. Let’s understand the terminology.

What is an air-conditioned highway? The split system consists of two blocks: external and internal. They are connected to each other using copper tubes and wires. They are just called a highway or highway. The track is mounted into the wall, having previously made a strobe.

Laying the route. Briefly

In short, the installation of the route for the air conditioner looks like this:

1.The exact installation location of the wall unit is indicated. The final height of the ceilings in the room, the width of the ceiling skirting board/baguette, the size of the block are taken into account. A place for installation is marked on the wall;

  1. The wall is drilled with a perforator, and a technological hole is also made in the external load-bearing wall of the house;

  2. Air conditioner pipes and wires are placed in the strobe and through the hole. Then the track is sealed with plaster, and the hole is closed with mounting foam and a decorative plug; 4.Blocks (external block and internal block) are connected to the communications.

Step-by-step instructions

We have divided the process of laying the route for air conditioning into several stages, so that it is clearer to you. Any other questions? Write them in the comments below.

Below we describe the easiest way to lay the route of the air conditioner. This manual is suitable for beginners. Please note that professional craftsmen perform such work with greater care.

Marking and strobing of the wall

First, you need to make a markup where the internal wall unit will be located. It is important to take into account many nuances: where the curtains will be located, what width the ceiling skirting board will be, what is the final height of the ceilings. Taking into account all these features, a marking is made on the wall.

It is also necessary to mark the place for strobling, so that it will be more convenient for you to lay the track in the future. The width of the strobe should be 5-10 cm. It is important that when laying pipes there are no too frequent and diverse kinks, they should be smooth and with the same angle. Also note that the slope should be the same throughout the entire route for air conditioners.

Now you need to drill a hole in the external load-bearing wall of the house. A drainage tube and possibly wires will exit through this hole. Use a hammer drill for drilling. Drill at a slight angle. The diameter of the hole should be 4-5 cm, it should be at a distance of 15-20 cm down from the window sill.

Be careful when performing the work! Fragments of the wall falling from above during drilling can be dangerous for passers-by.

Next, we proceed to the most physically difficult work — strobling. As we said above, its width should be 5-10 cm (depending on the number of tubes and wires). The depth is usually equal to the width of the strobe. Also, some masters reduce the depth, but increase the width of the route.

First, use a grinder to cut through the wall to the required depth and simplify further work. Then, using a puncher, remove unnecessary sections of the wall to form a strobe.

Selection and calculation of the number of materials

Copper tubes. The diameter of the air conditioner pipes is selected based on the power of the device. For low-power split systems (up to 4 kW), choose tubes with a diameter of 6 or 10 mm. The length of the tubes must be calculated. Take into account the length of the gate, the thickness of the external load-bearing wall of the house, add another meter and a half and get the optimal length. This will be enough to make the necessary bends, including on the street.

Cable connecting the blocks. For low-power split systems (up to 4 kW), you will need a five-core wire. A cross-section of 1.5 mm2 is suitable. The cable length should be selected according to the same principle as the length of the tubes, i.e. taking into account the length of the gate, the thickness of the outer wall and other parameters. Usually the length of the interblock wire is 20-50 cm longer than the copper tubes.

Drainage pipe. You will need a corrugated tube with a diameter of about 16 mm. If you do more, dust, insects and poplar fluff will be more likely to get into the tube. They will end up in the tube in any case, but with smaller pipe diameters, you will be less likely to clean the tube from blockages. Choose the length of the drainage hose according to the same principle as the length of the copper pipes and the interblock wire. Usually 1.5 meters is enough.

Other wires. It is better to add an additional three-core cable with a cross section of 1.5 to the air conditioner route. It may be needed for additional power supply to the outdoor unit, or for connecting sensors that can be included with the device.

Correct installation

The most important stage has come — the laying of communications. Start the installation of the route with the removal of communications into the hole on the street. Put thermal insulation-flex on all pipes. Connect the tubes together, fasten their beginning with an adhesive tape. It is this part of the highway that you will stick out into the street through a hole in the wall. You can make a note on the length of the tubes so that only the part of the route that you have designed is located on the street.

Laying a route for an air conditioner in strobe will require you to follow several important rules:

  • The drainage pipe throughout the entire channel under the communications of the air conditioner should be laid at a slight slope so that the condensate can flow through it naturally;

  • All tubes are arranged in the following order: on the left — the drainage tube, on the right-copper tubes and wires (if necessary);

  • If there are other wires in the strobe (for example, leading to the light switch), it is better to remove them so as not to interfere with the laying of the route for the split system;

  • Thin tubes should be bent carefully, avoiding fractures. If the diameter of the tubes is more than 10 mm, use a special tool to bend them.

Do not forget to securely fix the route for the air conditioner. To do this, it is better to use a mounting punched tape. In the required order, fix the route in the place where it exits to connect to the indoor unit.

Last steps

The laying of the route for air conditioning is almost finished. It remains to bring the wires (usually the owner of the air conditioner does this) and connect the blocks. It is also necessary to plaster the strob (finishers are engaged in this). After plastering and finishing, it is important to remember exactly where the highway is located, and inform the household about it, so as not to inadvertently damage the highway in an attempt to hang a picture.

That’s all, the installation process of the air conditioner route can be considered complete. As you can see, laying the route of the air conditioner is a multi-stage, complex process. Before carrying out the work, soberly assess your strength. Make sure that you can really perform the installation efficiently and in compliance with the technology.

Results

Laying the route under the air conditioner is a troublesome matter. It will require not only physical strength from the master, but also an understanding of many important nuances. You need to keep them in mind throughout the installation process.

It is for this reason that we do not recommend that home craftsmen carry out the installation of these air conditioners themselves. In theory, of course, you can conduct a highway without assistance, but it is important to understand that laying a route for an air conditioner is the most important stage when installing a split system.
