1.
Disconnect the expansion tank from the solar
installation. This avoids the access of dirt
particles present in the pipes to the expansion
tank. Observe the separate instructions
regarding the expansion tank!
2.
The return ball valve [b] must be closed
(90° position, see page 14).
3.
Connect the flush and fill station:
- Pressure hose to the fill valve [d]
- Flush hose to the drain valve [h].
4.
Open the fill and drain valves [d|h] and put the
flush and fill station into operation.
5.
Slowly open and close the return ball valve [b]
and the drain valve [k] during flushing in order
to vent the pump section.
6.
Flush the solar circuit until the solar fluid exits
without bubbles (see page 15).
7.
Close the drain valve [h] with the filling pump
running and increase the system pressure to
about 5 bars. The system pressure can be read
on the pressure gauge [e].
8.
Close the fill valve [d] and switch off the pump
of the flush and fill station.
9.
Check the pressure gauge to see whether the
system pressure reduces and eliminate leaks
where necessary.
Observe the pressure (max. 6 bars)!
