There is a water inlet and outlet per manifold (e.g. per snout, so 2 per module).
The inlet is the copper pipe pointing from flange to FLOBBER (along the snout).
The outlet is the copper pipe pointing vertically (transverse to snout).
The water pump rate per module should be ~1 Litre Per Minute.
The water temperature should be room temperature to avoid condensation.
There is a gas connection on each snout. One is the inlet and the other is the outlet (can be either way around).
The gas flows through the snout into the manifold, then throw the straws into the other manifold and out of the other snout.
The gas flow rate per module should be 0.2 Litre Per Minute.
