Combination indoor units

The indoor units connectable to the outdoor unit are shown below.

:

1. The total capacity(in Btu/h unit) of connected indoor unit models represents the total sum of the figures

expressed in the indoor model name.

2. Combinations in which the total capacity of the connected indoor units exceeds the capacity of the

outdoor unit will reduce the capacity of each indoor unit below the rated capacity during simultaneous
operation. Therefore, if circumstances allows, combine indoor units within the capacity of the outdoor unit
