When you install the unit, make first refrigerant connections and then electrical connections. Connect the air conditioner to grounding system before performing the electrical connection. If unit is uninstalled, first disconnect electrical cables, then refrigerant connections.
If the outdoor unit is more than 5 meters away from the indoor unit, you must extend the cable. The maximum length of the cable is 15(09/12)/20(18/24) meters.
1. Extend the assembly cable if necessary.
• Do not connect two or more different cables to extend the length. It may cause fire.
2 . Open the front grille.
3 . Remove the screw securing the connector cover.
4 . Pass the assembly cable through the rear of the indoor unit and connect the assembly cable to terminals. (Refer to the picture below)
• Each wire is labeled with the corresponding terminal number.
5 . Pass the other end of the cable through the 65mm hole in the wall.
6 . Close the connector cover by tightening the screw carefully.
7 . Close the front grille.

• After connecting the cables, make sure terminal numbers on the indoor/outdoor unit matches.
• Screws on terminal block must not be unscrewed with the torque less than 12kgf•cm.
10. Connect the grounding conductor to the grounding terminals.
11. Close the terminal board cover by tightening the screw carefully.
• In Russia and Europe, consult with the supply authority to determine the supply system impedance before
installation.
• Connect the wires firmly so that wires can not be pulled out easily. (If they are loose, it could cause
• Connect the wires according to color codes, referring to the wiring diagram.
