2.5. Constraints on indoor unit installation
You should note that indoor units that can be connected to this outdoor unit are the following constraints.
• Indoor units with model numbers 04-96 can be connected.
• When using Branch box, Indoor units with model numbers 06-36 can be connected.
• Refer to the table 1 below for possible room, indoor unit combinations.
Verification
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.
• MXZ-SM72 36 – 93 kBtu/h
• MXZ-SM96 48 – 124 kBtu/h
• MXZ-SM120 60 – 156 kBtu/h

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.
