9. Close the filling valve X2.
10.Open the stopcock X0. The valve X0 is open when the handgrip is parallel to the pipe.
11.With the help of the water system's pressure, set the system under a primary pressure of 1,5 bar. Use the filling
hose on filling valve X2 for that.
12.Pump the mixture through the system for about 30 minutes to remove air bubbles through the air vent.
13.Check the system pressure again and fill if necessary to rise the pressure.
14.Close the filling valve X1 and remove the filling hose.
15.Adjust the brine pump to the correct step.
