WARNING
• Indoor Unit ground Lines are required for preventing electrical shock accident in 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 equip-
ment utilizing the multiple power sources.
