Indoor and Outdoor Connection Wiring
When connecting the wiring harness between the indoor and outdoor unit, align the outdoor side and the indoor side with the terminal board No.
※When the wiring harnesses of the indoor and outdoor unit are not properly connected, it may cause trouble.
Be careful not to allow the indoor and outdoor wirings and power lines to get in contact with the service valve of the refrigerant system or to the pipe without an insulation.

Electrical Wiring
1.Connect it to the terminal board N and L for power cable to the outdoor unit.
In so doing, peel off the end of the power cord by about 5mm, and press the cord to the ring terminal for hooking.
-Make sure to install exclusive power supply.
If you use multiple connecting, there is a risk of electric shock or fire.
-If the outdoor power supply has been selected, install circuit breaker(ELCB). (Purchase separately)
-Make sure to connect earth wire.
-Make sure that the clamping force of the screw (on the terminal) is tightened firmly within the range of rated tightening torque.
-The appliance shall be installed in accordance with national wiring regulations for installation (SASO 2007:2002).
-Disconnection means must be incorporated in the fixed wiring in accordance with the wiring rules.
Connecting the power terminal
Connect the cables to the terminal board using the compressed ring terminal.
Use rated cables only and make sure to fix them without applying any external force to the terminal.
Connect the cables with driver and wrench that can apply the rated torque to the screws.
Make sure that appropriate tightening torque is applied for cable connection. If the terminal is loose, arc heat may occur and cause fire and if the terminal is connected too firmly, terminal may get damaged.

M3.5 | 8.0~10.0 |
M4 | 12.0~15.0 |
M5 | 20.0~25.0 |
