B When the fluid level has fallen to 25% in the filling
station, the pump should be stopped and more
collector circuit fluid should be filled and mixed.
B When the circuit is full and air no longer comes from
the return pipe, the pump should be run again for at
least 60 minutes (the fluid should be clear and should
not contain any bubbles).
B The circuit must be pressurized when venting is
complete. Turn the valves on the filling unit to
pressure increase position and pressurize the circuit
to 2.5 to 3 bar ( Figure 20).
