• All wires must be firmly connected.
• Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.
• The connecting wire between the indoor unit and the outdoor unit must be clamped by using provided cord anchorage.
• The power supply cord must be equivalent to H07RN-F which is the minimum requirement.
• Make sure no external pressure is applied to the terminal connectors and wires.
• Make sure all the covers are properly fixed to avoid any gap.
• Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching to
the indication on terminal block. (Refer to the wiring diagram attached on the unit).
