Stages of installation works

Correctly connect the air conditioner is possible only under the established work sequences. It involves:

  • study of circuit wiring;
  • training tools, equipment and consumables;
  • compound indoor and outdoor units via a cable and terminals;
  • connect the device to the mains;
  • check the functioning of the system.

Driving and connection rules

Before connecting the air conditioner to the power supply should be familiar with the scheme of the connection and installation work sequence.

Typically, such schemes are placed by the manufacturer on the internal and external modules. How to connect the steps covered in the instructions, which is necessarily present in the device configuration.

Tools and equipment

To perform the work required tools. Depending on the connection method it will include a drill, a set of screwdrivers, pliers and other tools. Of supplies may be required dowels, screws, plastic box and a cable such as clamps and other materials. Exact preparation of the list depends on:

  • connection options;
  • device model;
  • manufacturer's requirements.

Particular attention should be paid to the selection of equipment, which affects stable operation of the device. Whatever power the air conditioner from the power supply will be required:

  • the wire;
  • power socket;
  • circuit breaker.

Selection of wire

Wire under the air conditioner is selected in the cross section, length, and number of cores. These parameters are selected on the basis of:

  • current;
  • panel distance or the socket;
  • the number of phases.

For household appliances may be cross section from 1.5 to 2.5 mm.

Appliance conditioner usually has a single-phase connection, for which the selected three-conductor cable. More powerful industrial three-phase devices are different, which requires a five-wire.

Reliable operation of the device being connected via the outlet may be provided only when using copper wires. When using an aluminum conductor unit is powered via a separate line.

Requirements to an outlet

If the power will be supplied from the power outlet, you must first check its ability to withstand the workload.

Modern earthing-pin is typically designed to operate with high power devices. But in any case it is necessary to check compliance with certain requirements. It:

  • an earth and differential switch;
  • appropriate value specified in the instructions;
  • High compliance ratios mains power and low-power cooler;
  • is connected via a machine with a distance between the contacts is less than 3 mm at the open position.

The socket must be located at a certain distance from the floor and grounded metal Appliances:

  • 50 - 80 cm from the floor;
  • not less than 50 cm from the pipes, panels and other grounded objects from metal.

Machine

The circuit breaker is selected based on the rated power of the cooling device with a small margin, taking into account the level of the trigger current which is higher than the nominal. Machine with appropriate value can be selected according to the formula where device power divided by mains voltage and is increased by 30%. The best choice for home cooler Buda Machine type C, which best ensures safe loading and time triggered, if necessary.

Compound blocks and switch network

Before plugging in the connection is external and internal coolant blocks. To properly powered device must adhere to the following sequence during operation with the indoor unit:

  1. remove the outer panel;
  2. remove the cover from the terminals;
  3. dismantle the cable clamp;
  4. run a cable through a special opening in the back of the block;
  5. Strip the cable ends and tighten them to the terminals;
  6. secure lock wire;
  7. return the decorative cover.

Likewise, an external module is connected, in which the protective cover is dismantled. Before switching to the network is required to verify the correctness of the connection diagram.

Connect on a separate line

Such variant powering considered the safest for the smooth, continuous and safe operation. It is recommended:

  • for high capacity coolers;
  • when mounted on the initial stages of repair of the premises.

Line is placed in a plastic corrugated pipe and fastened to Stroebe plastic collars. It is possible without laying pipes Stroebe 20 mm deep. In the final stages of repair, or in the renovated premises of the line is laid in a plastic box. It is attached to the wall with glue or screws. The cable duct is fixed by plastic clips 500 - 600 m.

Precautionary measures

When laying a separate line is necessary to follow some rules that will save the unit from possible malfunctions:

  • all wiring elements must be accessible for maintenance;
  • wire strictly laid horizontally and / or vertically;
  • must not be laid under plaster several wires at a distance of at least 3 mm;
  • compound is not suitable for use by lay no special clips or bolts;
  • it is not necessary to connect the wires with copper and aluminum conductors.

In horizontal installation the cable must be respected distances from the ceiling beams, cornice moldings.

When the vertical distance from the laying openings and corners should be not less than 100 mm.

Particular attention should be paid to a parallel track laying a pipeline or a gas meter, where the recommended distance can not be less than one meter. When the vicinity of the hot pipe to protect cable insulation from the effects of high temperature.
