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 product is operating, attach a reversed phase protection circuit locally.
Running the product in reversed phase may break the compressor and other parts.
The GND terminal at the main PCB is a ‘-’ terminal for day contact,
it is not the point to make ground connection.
