about 5 bars. The system pressure is displayed
on the pressure gauge.
10. Check the pressure gauge to see whether the
system pressure reduces and eliminate leaks
where necessary.
11. Reduce the pressure at the drain valve [3.2] to
the operating pressure of the installation.
12. Connect the expansion tank to the solar circuit
and set the operating pressure of the solar
installation by means of the flush and fill station
(for the required operating pressure, see
instructions of the expansion tank).
13. Close the fill and drain valves [7.3|9.2|3.2].
