2.1.2.1 Installation with ball valve and non-return valve
For easy deaeration of the dosing head, we recommend that you install a ball valve (12) with a
bypass line immediately after the outlet valve.
In order to prevent backflow in the outlet line and to simplify startup, we recommend that you in-
stall a non-return valve (13) in the outlet line.
