Indoor unit capacity

Use the above tables to determine the capacities of indoor units to be connected. Make sure the 
total capacity of indoor units connected to each outdoor unit is within the specified value (kW).

!

The total capacity of connected indoor units must be within a range of 50 to 130% of the 
rated capacity of the outdoor unit.

!

In some models, it is not possible to connect the maximum number of connectable indoor 
units. Select models so the total capacity of connected indoor units conforms to the 
specification.
