How to wire
1. Remove the terminal cover by taking off the mounting screw (1 piece).
2. Connect the power supply wires and system interconnection wires to the terminal block of the electrical control
box.
3. Tighten the screws of the terminal block, connect the wires matching the terminal numbers (Do not apply
tension to the connecting section of the terminal block.)
4. Attach the terminal cover.
• When connecting the system interconnection wire to the outdoor unit terminal, prevent water from coming into
the outdoor unit.
• Insulate the unsheathed cords (conductors) with electrical insulation tape. Process them so that they do not
touch any electrical or metal parts.
• For system interconnection wires, do not use a wire joined to another on the way.
Use wires long enough to cover the entire length.
