Outdoor Unit Type
RAS-3.0HNSKQ
RAS-3.5HNSKQ
RAS-4.0HNSKQ
RAS-4.5HNSKQ
RAS-5.0HNSKQ
RAS-6.0HNSKQ
RAS-6.5HNSKQ
RAS-7.0HNSKQ
NOTE:
◆ The connectable indoor unit capacity ratio can be calculated as follows:
Connectable Indoor Unit Capacity Ratio = Total Indoor Unit Capacity / Total Outdoor Unit Capacity.
◆ For the same system, if the connectable indoor unit capacity ratio is over than 100%, and which all the
indoor units operate simultaneously, the capacity of every indoor unit should be less than its rated capacity.
◆ Indoor unit and outdoor unit connected to the total capacity of indoor units for the outdoor unit rated capacity of
50% to 130%.
