Installation of air conditioning with their own hands - a detailed overview of the installation and proper connection

Installation of air conditioning with their hands

The question of whether the air conditioning installation is possibledisturbs minds with his own hands, especially the owners of brand new split-systems, already had time to get acquainted with the prices for the installation of HVAC equipment. Indeed, numerous companies to install air conditioners quite appreciate their services, citing the complexity of the installation, the need for highly specialized expensive equipment and highly qualified specialists mandatory. With the last statement you can not argue. Only souped conditioners owners still interested in the possibility of self-installation, in the first place as the prospect of real savings in the payment of services for installation (it is the rather big sum), and secondly, as an opportunity to consolidate their own skills and learn something new. Can we blame our human desire to get to the heart of the matter, in order to understand how to install the air conditioner by yourself and make yourself installation, no worse than zapravsky master? If the desire is accompanied by the ability to realistically assess the level of their skills and capabilities, then it is priceless! The stated contact information on how to correctly install the air conditioner will help you to really appreciate the amount of work on the installation and proportioned with a level of skill required.

Before setting out to explore the detailed installation instructions, refer to the list of necessary equipment.

Necessary tools and equipment

  • Punch with the Boers.
  • Electric drill.
  • Vacuum pump.
  • Cutter.
  • Rolling.
  • Reamer (Flat skimmers).
  • Level.
  • Torque wrench.
  • Pressure collector

Bench tool for the installation of air conditioners will also be no more than (pliers, screwdriver, hammer, etc.)

Choosing a location for installation

Choosing the place of installation, both for internal as well asand outdoor units, consider the following points: It is important to consider the possibility of free access to the device (for in-line works on cleaning and replacing filters).

Consider the feasibility of the shortestcommunication between indoor and outdoor unit (it's not so much the economic benefits from the use of fewer consumables, how to reduce the efficiency of the entire system by increasing the length of interblock communications). Do not place the indoor unit on a high cabinet or furniture (barrier stream of cooled air will cause a decrease in the efficiency of operation of the device). For the same reason, a minimum distance from the ceiling and walls (15 cm). Reconciliation with your neighbors conditioner installation is also very desirable, in order to avoid misunderstandings in the future. Special problems installing the outdoor unit does not create a residents of neighboring apartments, but it is very likely that someone may not like the noise of a fan running or dripping condensate. And the last point, the most obvious - the cold air flow should not cause discomfort to the occupants in the room, so please note the direction of air flow during installation. After space layouts are defined, proceed to installation.

A detailed plan of installation works

  • Installation of the indoor unit;
  • mounting the outdoor unit;
  • channel drilled in the wall;
  • laying and connection of the connecting communications;
  • system evacuation circuit;
  • connect the air conditioner to the power supply;
  • launch sistemy.Pravilno install the indoor unit

The indoor unit of a split system is mounted ona special plate that came with the device. To ensure reliable operation of the unit and prevent leakage of condensate from it afterwards is very important to secure the plate evenly. Therefore, to determine a strict horizontal when marking must use the level. In the marked area in the pre-drilled hole puncher are driven dowels. Then, with screws, screw-in anchors fasten the mounting plate and set it in the indoor unit.

Mount the outdoor unit

The outdoor unit is placed on the preinstalled brackets on the outside of the building, as a rule, under a window or next to it for ease of maintenance. To effectively blowing away from the unit to the wall should be at least 10cm. If you can not fix the brackets out of the window, then to carry out the work required to rent aerial platform or to use the services of climbers.

Interblock communication - how to do?

Hole in the wall for passage of Communicationsare drilled using a rotary hammer drill with a diameter of 4-5 cm. If the inter-unit path will include a drain pipe for condensate drain, the channel needs to be done with a slope (5-10 degrees to the side of the street). The plot line from the indoor unit to the place of entry into the wall, it is desirable to hide in the wall. When shtroblenie produces a lot of dust, so if the room is already made repairs, it is better to pave the road outside, closing it later decorative boxes.

Installation of decorative plastic boxes

Interblock communication can be hidden in a decorative plastic housing

The interconnect includes a communication routecopper tubes freon lines, wires and electrical equipment control and drain piping (condensate from the indoor unit according to the rules must be discharged into the sewer, but many simply render it out). The necessary wiring and piping length is determined by measuring the total path length (plus a small margin of 30-50 cm).

For cutting copper tubing should be usedcutter, not grinders or hacksaw to avoid the sawdust that could subsequently cause damage to the air conditioner. Before installing the pipes are placed in the heat-insulating sheath, to prevent debris from entering the pipe hole is closed with plastic plugs. All components are placed along the track, rewind vinyl tape, after which the trail is put in place.

After laying interblock communicationsbegin connecting wires and freon line. Instructions for installing the air conditioner shall contain the wiring connection diagram, which should be guided in their work.

Adjusted length of the tubes (cut off the rightsize), then you must remove the burrs (chamfer using reamer). After threading nuts each tube is expanded by rolling the edge. Then, the edges connected to the connections on the indoor and outdoor units, tightening the nuts with a torque wrench (connections must be absolutely airtight).

Air conditioning system evacuation system circuit

After checking the tightness of the line by means of a vacuum pump removes the air manifold makes it possible to control the pressure

Finished connecting route, checkand sealing pipe "evacuated" it (remove moisture and air) with a vacuum pump. To this end, through the manifold to the service port of the outdoor unit is connected the vacuum pump, which pumped out the air from the system, creates a vacuum in it. This process continues for about 20 minutes (depending on the volume circuit). After switching off the pump watching for half an hour for the change of pressure, if the pressure gauge needle is not rejected, then the system is tight. Only after a thorough check of tightness possibly opening the outdoor unit valves and filling freon loop. Attention, freon leak can cause damage to the compressor, but more importantly an extremely harmful effect on the human body Freon.

Thus, the system is assembled and filled with refrigerant,remains conditioner electrical connection and check it works. The scheme is simple to connect the air conditioner, most household split-systems power supply is connected to the indoor unit, it is necessary only to bring him an outlet.

Now you have a general idea about how to install the air conditioner by hand. It was about the installation of a split system is the most effective kinds of household air conditioners.

Installation does not require a mobile air conditionerintervention of highly skilled professionals: it is only necessary to place the unit within 2 m from the window (to remove hot air), then connect to the network.
