Note:
* The environment conditions must be taken into consideration when the connections of power cable are made
(such as the ambient temperature, direct exposure to heat/dirext exposure to sunlight).
* The specifications for the power cable refer to the minimum values of the metal core wires, taking into
consideration the voltage losses, the core wire of power cable must be one size larger than the specifications.
* The grounding wire must be connected to the indoor units and outdoor units.
* The laying of power cables must be done by qualified electricians and comply with the regulations of the local
power supply authorities and with the standards of the electric appliance.
