(1) When it's modular units connection, the ODU must be installed in capacity order: ODU 4 ≥
ODU 3 ≥ ODU 2 ≥ ODU 1.
(2) Pipe "A" between the outdoor unit and the manifold of outdoor unit.
The pipe size is based on the capacity of upstream module.
(3) Fitting pipe "B" between outdoor unit manifold; fitting pipe "C" from outdoor unit to indoor
manifold.
Pipe size (between two manifolds from basic modules) is based on the total capacity of upstream
modules.
