Installing the air conditioner with your own hands

The air conditioner should be selected and installed in advance, without waiting for the summer heat. So you can save a significant amount, especially if you perform the installation yourself. To ensure that the equipment operates smoothly, the installation of the air conditioner by one's own hands must be carried out strictly according to the instructions at the appropriate place. Inconsistency of technical conditions or incorrect selection of parts will lead to a rapid breakdown of the split system.

The principle of the air conditioner

To properly install everything, you should have an idea of ​​the device and how the air conditioner works. It consists of a compressor and an evaporative unit, connected together by tubes. The compressor is mounted from the outside of the wall, and the evaporator is installed indoors. Expensive models have not one internal unit, but several that are connected to one compressor.

A high-pressure refrigerant is fed through the nozzle into the evaporator unit. It enters the evaporator chamber, expands, boils, and its vapors begin to absorb heat intensively. During this process, water condensate is released and settles on the evaporator block radiator. From there, moisture is sent to the reservoir and is led out of the building through the tube.

operation All this time, the compressor pumped the evaporation of the refrigerant from the chamber, increasing the pressure behind the pump. As a result, the refrigerant heats up and from the liquid turns into a fog of high density. In this condition, the coolant enters the radiator-equipped condensate chamber, is cooled by a fan, and again turns into a liquid. In this form, it is again fed under pressure into the evaporator nozzle and the working process is repeated.

The efficiency of the equipment and the power consumption directly depend on the operating conditions. If there is any heating device near the air conditioner, the compressor consumes more energy and more often fails. The usual dust that gets inside the system can also cause a breakdown, and therefore it is necessary to carry out a wet cleaning regularly and very carefully. You can not put the surface of the block various objects, and cover something.

To avoid evaporation of the refrigerant, all joints and joints must be carefully sealed during installation. The outdoor unit must be located lower than the indoor unit and, if possible, in the coolest place. Well, if the unit is constantly in the shade from the overhang of the roof or walls. Compliance with these conditions will ensure the uninterrupted operation of the air conditioner and a comfortable climate in the premises.

1. The	fan generates a flow of air blowing the condenser
2. The	condenser is a radiator in which refrigerant is cooled and condensed. The air passing through the condenser, respectively, is heated by the
3. The compressor	compresses Freon and keeps it moving along the refrigeration circuit. The compressor is of a piston type or a scroll type. Reciprocating compressors are cheaper but less reliable than spiral compressors, especially in low-temperature outdoor air conditions
4. The	control board is installed only on inverter air conditioners. In non-inverter models, all electronics are tried to be placed in the indoor unit, because the high temperature and humidity drops reduce the reliability of the electronic components of the
5. The four-way valve	is installed in reversible( heat-cold) air conditioners. In the heating mode, this valve changes the direction of Freon. In this case, the indoor and outdoor units are interchanged: the indoor unit is used for heating, and the outdoor unit is used for cooling
6. The	connections are connected to them by copper pipes connecting the outdoor and indoor units of the
7. The	freon filter is installed in front of the compressorand protects it from copper chips and other small particles that can get into the system when installing the air conditioner. Of course, if the installation is performed with a violation of the technology and a large amount of debris gets into the system, the filter will not help the
8. The protective quick-detachable cover	closes the choke connections and the terminal block used to connect the electrical cables. In some models, the protective cover covers only the terminal strip, and the union connections remain outside

Indoor unit of air conditioner	Description
1. The front panel of the	is a plastic grill through which air enters the unit. The panel is easily removed for maintenance of the air conditioner( filter cleaning, etc.).
2. The coarse filter	is a plastic mesh and is designed to delay large dust, animal hair, etc. For normal operation of the air conditioner, the filter must be cleaned at least two timesonce a month
3. The	fine filter is of various types: carbon( removes unpleasant odors), electrostatic( retains fine dust), etc. The presence or absence of fine filters has no effect on the operation of air conditioningThe
4. The	fan has 3 to 4 rotational speeds
5. Evaporator	radiator in which the cold freon is heated and evaporated. Air blown through the radiator, respectively, is cooled
6. The horizontal blinds	adjust the direction of the airflow vertically. These blinds have an electric drive and their position can be adjusted from the remote control. In addition, the louver can automatically perform oscillatory movements to evenly distribute the air flow through the room
7. The indicator panel	on the front panel of the air conditioner has indicators( LEDs) showing the operating mode of the air conditioner and signaling possible malfunctions of the
8. Vertical blinds	serve for adjustmentdirection of the airflow horizontally. In domestic air conditioners, the position of these blinds can only be adjusted manually. The possibility of adjustment from the remote control is available only in some models of air conditioners of the premium class
Condensate tray	is located under the evaporator and serves to collect condensate( water formed on the surface of the cold evaporator).From the drip tray, water is discharged through the
drain hose. The	control board is usually located on the right side of the indoor unit. On this board there is an electronics unit with the central microprocessor
. The	connector connections are located in the lower rear part of the indoor unit. They are connected with copper pipes connecting the outdoor and indoor units

Tools for installing the air conditioner

When installing the air conditioner yourself, you must prepare all the tools you may need in advance:

• vacuum and bicycle pumps;
• tester for electrical wiring;
• indicator;
• pipe cutter;
• manometer;
• punch;
• pipe expanding set;
• Example.
  

  Tools for working

In addition, you will need a whole bay of copper tube with factory-sealed ends. Scratches, dents and similar defects are not allowed.

Installing the air conditioner is best during the overhaul, as it will have to pierce the wall and damage the finish.

How to install the air conditioner

If the tools are purchased, the air conditioner is delivered and unpacked, you can start working. The first install an outdoor unit, and then mount the system indoors. During the installation, you must not forget about safety, especially if the work is done at the level of the second floor and above.

Outdoor unit mounting

When installing an air conditioner in a private house, there are no special difficulties for placing an outdoor unit, but in a multi-apartment building a place needs to be chosen very carefully. The body of the unit should not obstruct the view of neighbors, and the condensate should not flow down the wall of the house. At the same time, the air conditioner should be secured within reach from the balcony, since such equipment needs periodic maintenance.

It is best if the unit is fixed to the east or north side of a window or balcony, and preferably at its bottom. So it will not interfere with anyone, and you can reach it without difficulty through an open window. With the help of the level mark the places of fixing the brackets and drill holes in the wall under the anchor bolts. For laying interblock communications, a through hole with a diameter of 80 mm is drilled. In a brick wall, it is recommended to drill at the seam between the bricks - this will take less time and the hole will be more accurate.

Brackets The brackets are aligned, aligned and securely bolted. The outdoor unit itself is fixed so that there is at least 10 cm between the radiator and the wall surface. The connection is made a little later, then the gaps formed are closed. If the unit is securely fastened to a vertical surface, you can proceed to the next step.

Installing the indoor unit

The indoor unit can not be mounted behind curtains, above the battery and in rooms with electrical interference sources, which can cause a breakdown of the block processor. After choosing a place, you must check the wall for the absence of already laid out communications - electrical wiring, water pipes or heating pipes.

indoor unit If the site is free, mount the mounting plate: retreat from the ceiling 10 cm, from the wall angle of 5 cm and mark with a pencilhorizontal line. Drill the holes under the fasteners and screw the plate securely. The inner unit of the air conditioner is mounted on the plate, after which a hole for the communication connection is drilled in the side wall - electrical wiring, pipes, hoses for condensate drainage.

Wiring connection

For indoor unit lay their own wiring, the minimum cross-section of which is 1.5 square meters.mm. It is mandatory to install the circuit breaker. When the wiring is laid, it is connected to the flap on the input: a yellow wire with a green strip is connected to the zero wire. To determine zero and phase, use the indicator.

After this, the isolated terminals of both blocks are connected by insulated multicore wires, passing them through the hole in the wall. The names of the terminals must necessarily coincide with the wires, the entire wiring diagram is clearly indicated in the instructions attached to the air conditioner.

Pipe gasket

Copper tubes must be cut, leaving a margin for bends about a meter. When bending tubes use special tools that avoid wrinkles, dents and cracking of the metal. On the prepared pipes wear thermal insulation - polyurethane foam hoses. Foam as a sealant is not suitable, since it has a short service life.

Insulate threaded flanges on insulated pipes, the thread should be located at the end of the tube. The next stage is flaring the tubes. The flaring should be done very carefully, so that the cracks and grooves do not form on the tubes. The nut should be easy to put on the rolling, and the tightening is best done with a torque wrench - this eliminates the squeezing of the flared connections from the nut.

Alternately, pipelines are fastened to the corresponding fittings, which are difficult to confuse due to different diameters. At the unions, tighten the flanges so that the connection is tight, but not pinched, otherwise there is a risk of damaging the tube. Finally, a piece of plastic tubing with a reinforced shell is connected to the drain connection. Fastening is carried out by a piece of a heat-shrinkable tube or a threaded flange, if it is included in the kit. Drain the tube as far as possible from the supporting wall.

The pipes are now threaded into the hole, aligned, on the outside, fixed tightly to the wall with clamps. Next, fix the wiring cable, connect the pipeline to the external unit. The hole is blown with a mounting foam or filled with silicone. All external connections are checked with a bicycle pump and soap solution for leaks. If somewhere passes the air, thread tightens tight. After checking, the soap coating is wiped off the thread with a clean rag.

Evacuation of

system The vacuuming of the system makes it possible to remove minute dust particles and moisture. This process is carried out after sealing the threaded connections, otherwise it will not be possible to completely deflate the air. For this, a vacuum pump is connected to the system and air is pumped out within an hour.

Filling and testing the air conditioner

Refrigerant from the cylinder must be pumped into the system. An adapter and a manometer are connected to the cylinder, and then, strictly following the pressure, fill the tank. When the process is completed, the air conditioner is equipped with a disconnect switch, after which the system automatically enters the test mode. If everything works without failures, and the circulation of cold air becomes uniform, you can close the hole in the wall, remove the effects of installation and enjoy the coolness.
