For optimal distribution of the refrigerant, you must use Y-joint as branch joint for connecting outdoor units. (Do
not use T-joint)

When you install the outdoor units in module, there is no restriction of installation order among outdoor units.

Height of the connection pipe should be same or lower than the ones connected to the outdoor units.
