The rated capacity should be determined by observing the table below. The unit's
quantities are limited as shown in the following table 2. For the next step, make
sure that the total rated capacity selected will stay in a range of 50% - 130% of the
outdoor unit capacity.

Combinations in which the total capacity of indoor units exceeds the capacity of the
outdoor unit will reduce the cooling capacity of each indoor unit below their rated
cooling capacity. Thus, combine indoor units with an outdoor unit within the outdoor
unit's capacity, if possible.
