6. Connecting the venting pipe.
The DN 50 vent port on top of the tank is open. Connect the
venting pipe to the vent port via a flexible connection piece.
The venting pipe must be led out above the roof into the open
air in accordance with local regulations. A flexible connection
can be ensured if a distance of approx. 3 cm is left between
the venting pipe end and the vent port.
7. Connecting the diaphragm pump (optional).
Fit the diaphragm pump on the discharge side. To facilitate
servicing of the diaphragm pump, we recommend fitting a 1½"
isolating valve to the tank port.
