To start or stop 10-day brine pump
operation
If a brine buffer vessel is part of the brine circuit, or in case a
horizontal brine loop is used, it may be required to let the brine pump
run continuously for 10 days after the system is commissioned. If 10
day brine pump operation is:
▪ ON: The unit operates as normal, except that the brine pump
operates continuously for 10 days, independent of compressor
status.
▪ OFF: Brine pump operation is linked to compressor status.
Conditions: All other commissioning tasks have been completed
before starting the 10 day brine pump operation. After you have
done this, 10 day brine pump operation can be activated in the
commissioning menu.

operation.
