ELECTRICAL WIRING CONNECTION
IMPORTANT :
* The figures shown in the table are for information purpose only. They should be checked and selected
to comply with the local/national codes of regulations. This is also subject to the type of installation and
conductors used.
** The appropriate voltage range should be checked with label data on the unit.
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).
