2.1.2.2 Installation of the inlet line
When you install the inlet line, observe the following points:
•
Keep the inlet line as short as possible. Avoid tangling.
•
Use swept bends instead of elbows.
•
Always run the inlet line up towards the inlet valve.
•
Avoid loops. Loops may cause air bubbles.
2.1.2.3 Installation with pressure-relief valve
To protect the dosing pump and outlet line from excessive pressure, we recommend that you in-
stall a pressure-relief valve (6) in the outlet line.

2.1.2.4 Installation on a tank
When dosing non-degassing media with a viscosity similar to that of water, the pump can be
mounted on a tank.
•
Observe the maximum suction lift.
•
For sedimenting media, we recommend that you install an inlet line with a filter (14). Install
the foot valve 10 mm above the possible level of sedimentation.
