1 Outdoor Unit - 3Ø, 208/230V
WARNING
• Indoor Unit ground Lines are required for preventing electrical shock accident during current leakage,
Communication disorder by noise effect and motor current leakage (without connection to pipe).
• Don't install an individual switch or electrical outlet to disconnect each of indoor unit separately from the power supply.
• Install the main switch that can interrupt all the power sources in an integrated manner because this system consists of the
equipment utilizing the multiple power sources.
• If there exists the possibility of reversed phase, lose phase, momentary blackout or the power goes on and off while the prod-
uct is operating, attach a reversed phase protection circuit locally.
Running the product in reversed phase may break the compressor and other parts.
