The GND terminal at the
main PCB is a ‘-’ terminal
for dry contact, it is not
the point to make ground
connection.
WARNING
• Indoor Unit ground wires 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.

In case of Heat Recovery System
Between Indoor and Master Outdoor unit
The communication cables between indoor unit and master outdoor
unit are possible to connect with BUS type or STAR type.
The GND terminal at the main PCB is a ‘-’ terminal for dry contact.
It is not the point to make ground connection.
- Make sure that terminal number of master and slave outdoor units
are matched.(A-A, B-B)
WARNING
• Indoor Unit ground wires 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.
!
WARNING
When the total capacity is over than as follow, the power source
do not use in series between the units.
The First terminal block could be burnt out.
!
- Connection of communication
cable must be installed like
below figure between indoor
unit to outdoor unit.
- Abnormal operation can be
caused by communication
defect, when connection of
communication cable is installed
like below figure(STAR type).
