①
Install the disconnect device with a contact gap of at least 3mm in all poles nearby the units
(Both indoor unit and outdoor unit).The appliance must be positioned so that the plug is
accessible.
②
The specifications of the breaker and power cable listed in the table above are determined based
on the maximum power (maximum amps) of the unit.
③
The specifications of the power cable listed in the table above are applied to the conduit-guarded
multi-wire copper cable (like, YJV copper cable, consisting of PE insulated wires and a PVC
cable jacket) used at 40°С and resistible to 90°С (see IEC 60364-5-52). If the working condition

changes, they should be modified according to the related national standard.
④
The specifications of the breaker listed in the table above are applied to the breaker with the
working temperature at 40°С. If the working condition changes, they should be modified
according to the related national standard.
