You can connect the flat collectors hydrauli-
cally in four different ways, as shown in the
illustration.
However the direction of flow is always from
bottom to top.
If you connect 1 to 5 collectors one after
another, the hydraulic connections can be
laid one below the other on one side.
If you connect 6 to 12 collectors one after
another, the hydraulic connections must be
arranged diagonally, to force a complete flow.
