Installing indoor units
Under 16.0 kW indoor unit : Don’t use Y-connector
16.0 kW ~ 28.0 kW indoor unit : Use Y-connector at the Gas & Liquid line
If you want to continuous cooling operation under -5 ℃, set outdoor ‘Expand operational
temperature range for cooling operation (HR only)’, and use Y-connector on 5.0 ~ 16 kW indoor unit
In case of using Y-connector, it is only connectable for port combination at below
Connectable port combination for Y-connector : A + B port, C + D port, E + F port
Non-connectable port combination for Y-connector : B + C port, D + E port, non-continuous port
Set Dip Switch option for using Y-connector
This unit is only
connectable for one port
under 16 Kw
This unit is impossible
to connect MCU to MCU
in series.
