NOTE:
All pumps are self-priming, no overpressure is necessary at the tanks!
If the sample tube waste and the receiver waste shall be collected in the same tank, the Y-piece

Cooling water connection
Screw the cooling water hose to the cooling water inlet on the device side and connect it to the water
