How to connect wiring
Precautions
Remove the control box lid of the indoor unit.
Remove the cover of the outdoor unit.
Follow the "Wiring diagram label" attached to the indoor unit's control box lid to wire the outdoor unit, indoor unit, and remote control.
Securely fix the wires with a field-supplied clamp.
Attach the cover of the outdoor unit.

Observe the notes mentioned below when wiring to the power
supply terminal board.
Use the specified electric wire. Connect the wire securely to
the terminal. Lock the wire down without applying excessive
force to the terminal. (Tightening torque: 1.31 N.m±10%).
- Do not connect wires of a different gauge to the same
power supply terminal. Looseness in the connection may
cause overheating.
- When connecting wires of the same gauge, connect them
according to the following figure:
1
- When attaching the control box lid, make sure not to pinch
any wires.
- After all wiring connections are done, fill in any gaps in the
casing wiring holes with putty or insulation material (field
supplied) to prevent small animals or dirt from entering the
unit and causing short circuits in the control box.
Do not connect wires of a different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
Use only specified wires and tightly connect them to the terminals.
Be careful that the wires do not place external stress on the
terminals. Keep them in neat order so that they do not obstruct other
equipment, such as by popping open the service cover. (Make sure
the cover closes tightly.) Incomplete connections could result in
overheating and, in the worst case, electrical shock or fire.
