Technical description
•
The flow indicators in the flow
distributor must be in the fully open
position (factory setting). They do not
serve to set the flow rates!
•
The position of the indicator ring in
the sight glass has no direct relation
to the flow rate set on the QM valve
insert.
Install ball valves in front of the flow
distributor/return collector to shut off
the supply and return pipe.
