• Connect a power cable of the outdoor unit after checking that R-S-T (3 phase 3 wire) is properly connected.
• Malfunction may occur if one or more of the wires among R-S-T phases (3 Phases-3 Wires) are not connected properly.
(*Malfunction: Turning on/off, occurrence of error, consecutive reset)
• Communication cable between indoor and outdoor units and communication cable between outdoor units has no polarity.
• Arrange the cables with a cable tie.
