question of whether it is possible installation of air conditioning with their hands worried minds, especially the owners of brand new split-systems have 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 expensive highly specialized equipment and highly qualified specialists mandatory.With the last statement I will not argue.Only souped owners conditioners still interested in the possibility of self-installation in the first place as the prospect of real savings to pay for the 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 do the installation yourself, no worse than zapravsky master?If the desire is accompanied by

the ability to realistically assess the level of their skills and capabilities, it is not the price!The stated contact information on how to correctly install the air conditioner will help you really appreciate the amount of work on installation and proportioned with a level of skill required.

Before studying the detailed installation instructions, refer to the list of necessary equipment.

Necessary tools and equipment ↑

  1. Hammer with the Boers.
  2. Electric drill.
  3. vacuum pump.
  4. Cutter.
  5. Rolling.
  6. Rimer (faskosnimatel).
  7. level.
  8. wrench.
  9. manifold.
The pump for pumping air from the air conditioning system
Using a vacuum pump removes moisture and air from the system

Bench tool for air conditioning will not be superfluous (pliers, screwdriver, hammer, etc.)

Choosing a location for installation ↑

choosing the installation location,for interior and exterior blocks, consider the following: it is important to consider the possibility of free access to the device (for in-line work on cleaning and replacement of filters).

Consider the feasibility of the shortest connection 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 with an increase in the length of interblock communications).Do not place the indoor unit on a high cabinet or furniture (impedes the flow of cooled air will cause a decrease in the efficiency of the device).For the same reason, a minimum distance from the ceiling and walls (15 cm).Harmonization of the air conditioner with the neighbors is also very desirable, in order to avoid misunderstandings in the future.Special problems installing external power to residents of neighboring apartments does not create, but it is very likely that someone may not like the noise of the fan or dripping condensate.And the last point is the most obvious - the flow of cool air will not cause discomfort to people in the premises, so please note the direction of air flow during installation.Once the location of the blocks defined, proceed to installation.

detailed plan for installation work ↑

  • installation of the indoor unit;
  • mount the outdoor unit;
  • drilled in the wall of the channel;
  • laying and connection of the connecting communications;
  • system evacuation circuit;
  • connect the air conditioner to the mains;
  • system startup.

properly install the indoor unit ↑

indoor unit of a split system is mounted on a special plate that came with the device.To ensure reliable operation of the unit and to prevent leakage of condensate subsequently it is very important to secure the plate evenly.Therefore, to determine a strict horizontal when you must use the level layout.In the marked places in the pre-drilled hole puncher are driven dowels.Then, using the screws, screwed into dowels fasten the mounting plate and set it in the indoor unit.

Mount the outdoor unit ↑

outdoor unit is placed on the pre-installed brackets on the outside of the building, as a rule, under the window or on the side of it for ease of maintenance.To effectively blow away from the unit to the wall should be at least 10cm.If you can not fix the brackets of the window, for the work required to rent or use the aerial platform climbers.

Interconnect communication - how to do?↑

hole in the wall for the passage of communications drilled using the gun drill diameter of 4-5 cm. If the inter-unit path will include a drain pipe for condensate, the channel must be made 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 the wall.When shtroblenie produces a lot of dust, so if the room had been renovated, it is better to pave the road outside, then closed her decorative boxes.

Interconnect communications can be hidden in a decorative plastic case

The interconnect communication route includes copper tubes freon lines, wires power and control equipment, and drain piping (condensate from the indoor unit according to the rules should be discharged into the sewer, but many simplyoutput it to the outside).The required length of the wiring and piping is determined by measuring the total length of tracks (plus a small margin of 30-50 cm).

For cutting copper tubing cutter should be used, rather than a hacksaw or grinder, to avoid any sawdust that could subsequently cause damage to the air conditioner.Before installing the pipes placed in a heat-insulating sheath to prevent the ingress of debris cover the hole with plastic pipe plugs.All components are placed along the track, rewind vinyl tape, after which the route is set in place.

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

Adjusted length of the tubes (cut the desired size), then you must remove the burrs (chamfer using reamer).After threading nuts each region is expanded by rolling tubes.Then the edge of the fittings connected to indoor and outdoor unit, tightening the nuts with a torque wrench (connections should be completely sealed).

System evacuation circuit of the air conditioner
After checking the tightness of the line using a vacuum pump removes the air manifold makes it possible to control the pressure

finished connecting route, check the tightness of lines and "evacuated" it (remove moisture and air) with a vacuum pump.To do this through the manifold to the service port of the outdoor unit is connected vacuum pump, which is pumping out the air from the system creates a vacuum in it.This process takes about 20 minutes (depending on the volume of the circuit).After switching off the pump for half an hour watching the change in pressure when the pressure gauge is not rejected, then the system is tight.Only after a thorough check of tightness possibly opening valves of the outdoor unit and filling refrigerant circuit.Attention, leaking refrigerant may 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, it remains to connect the air conditioner to the power supply and check her work.Wiring the air conditioner is simple, 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.It will help to understand how to install air-conditioning Video instructions given below.

Installing mobile air conditioner does not require the intervention 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.
