6.6 Installation tips
•
For easy deaeration of the dosing head, install a ball valve
(11i) with bypass line (back to the dosing tank) immediately
after the discharge valve.
•
In the case of long discharge lines, install a non-return valve
(12i) in the discharge line.

•
When installing the suction line, observe the following:
– Keep the suction line as short as possible. Prevent it from
becoming tangled.
– If necessary, use swept bends instead of elbows.
– Always route the suction line up towards the suction valve.
– Avoid loops which may cause air bubbles.
