The rated capacity should be determined by observing the table below. The unit’s quantities are limited in 2 to 8 units.
For the next step, make sure that the selected total rated capacity is in a range of 12 ~ 70.2 kBTU/h.
The total indoor unit capacity should be within the outdoor units. (=54.0 kBTU/h is preferred).
Combination of excessive indoor units and an outdoor unit may reduce the capacity of each indoor unit.
The rated indoor capacity is as the table below.
