8.2.2
To perform an air purge on the brine
circuit
There are two ways to perform an air purge on the brine circuit:
▪ with a brine filling station (field supply)
▪ with a brine filling station (field supply) in combination with the
unit’s own brine pump
In both cases, follow the instructions included with the brine filling
station. The second method should only be used when the air purge
on the brine circuit was NOT successful using only a brine filling
station. See “To perform an air purge with a brine filling station” in
the installer reference guide for more information.
In case a brine buffer vessel is present in the brine circuit, or if the
brine circuit consists of a horizontal loop instead of a vertical
borehole, further air purging may be required. You can make use of
the
10 day brine pump operation
. See
