3.5 Installing the PurCon air outlet (option)
We recommend to install the PurCon air outlet if the drain pipe is not
entirely pressure-free. By using the air outlet, no overpressure can
develop in the system which prevents the retentate from running off.
The PurCon air outlet is mounted on the filler nozzle instead of the cap.

tube nozzle and lead the other end of the tube into the open or
into a discharge.
