When both units of the air conditioner are installed, it is necessary to conduct electrical wires and connect them to the network, the electrical circuit of the air conditioner is a guide for this.
We connect the indoor and outdoor units
First you need to connect the two air conditioning units to each other. And only after that an electric cable is mounted connecting the indoor unit to the common apartment system.
The air conditioner circuit is not the same for different models. Appliances for apartments are most often connected to one phase. Three phases are necessary for connecting amplified power devices.
Using existing wiring
Connecting the wires of the air conditioner to the wiring in the apartment is allowed if the electrical circuit allows it and:
- Low power device;
- Window or mobile;
- If the network is designed for high loads;
- As a temporary solution to the problem;
- A separate line has been allocated for the air conditioner, to which powerful appliances are not connected.
The wiring diagram for the air conditioner is the main document to be guided by.
It is forbidden to connect to a ready-made electrical network if:
- The network is laid with aluminum wires;
- Small cross-section wires;
- No grounding and special protective systems;
- Wires are old or damaged.
If the device is connected to a ready-made network, it is necessary to install a differential machine and an emergency shutdown mechanism.
The circuit diagram provides for the installation of the machine at least 20 A.
Separate power line
This type of connection has many advantages.
The device is not subject to power surges, overloading the network itself is impossible. A special wire to the device can be connected anywhere in the room.
The connection diagrams of the outdoor and indoor units, as well as the electrical circuit diagram of the air conditioner, are applied to the back of one of the units of the device.
Power Line Parameters:
- The line must be equipped with an automatic machine;
- Without fail, grounding;
- Only copper wires are laid;
- The cross section of the wire should be no less than 3 to 2.5.
When connecting an air conditioner to the electrical network, you should definitely resort to the user manual, in which there is a circuit diagram for connecting the air conditioner of this particular type.
If there is separate wiring to the device, it is not necessary to mount the differential machine and the emergency shutdown mechanism of the indoor unit.
