●Be sure to connect power wires correctly matching up numbers on terminals of the outdoor unit and respective indoor units A – D.

CAUTION

WARNING

●To avoid the risk of electric shock, each air conditioner unit must be grounded.

●For the installation of a grounding device, please observe local electrical codes.

●Grounding is necessary, especially for units using inverter circuits, in order to release charged electricity and electrical noise caused by high tension.

Otherwise, electrical shock may occur.

●Place a dedicated ground more than 2 meters away from other grounds and do not have it shared with other electric appliances.
