8.3 Piping selection
When several modules are connected, the installation sequence of ODU 1-4 shall meet the following
requirement: ODU 4 ≥ ODU 3 ≥ ODU 2 ≥ ODU 1.
(1) Piping "A"of ODU and ODU branch
Choose pipe diameter according to the ODU capacity connected to the upstream of ODU branch.
Basic module (single module system)

GMV-280WM/G-X
GMV-335WM/G-X
GMV-400WM/G-X
GMV-450WM/G-X
GMV-504WM/G-X
GMV-560WM/G-X
GMV-615WM/G-X
