There are 2 ways to perform an air purge:
▪ with a brine filling station (field supply),
▪ with a brine filling station (field supply) in combination with the
unit's own brine pump.
10‑day brine pump operation. If a brine buffer vessel is part of the
system, 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.
To perform an air purge with a brine filling station
Follow the instructions included with the brine filling station (field
supply).
To perform an air purge with the brine pump and a
brine filling station
Prerequisite: Performing an air purge on the brine circuit was NOT
successful using a brine filling station only (see "To perform an air
purge with a brine filling station" on page 21 ). In this case, use a
brine filling station and the unit's own brine pump simultaneously.
1 Fill the brine circuit.
2 Start the brine pump test run.
3 Start the brine filling station (MUST be started within a time
frame of 5~60 seconds after starting the brine pump test run).

Result: The brine pump test run starts running, starting the removal
of air from the brine circuit. During the test run, the brine pump
operates without actual operation of the unit.
INFORMATION
For details on starting/stopping the brine pump test run,
see
"6.2.5 To perform an actuator test run" on page 21 .
The brine pump test run stops automatically after 2 hours.
To start or stop 10-day brine pump operation
INFORMATION
The 10‑day brine pump operation procedure includes the
activation of the brine pump test run. Because the
procedure provides limited time for this, it is required that
the brine pump test run be activated as fast as possible.
For instructions, see the "Commissioning" chapter in the
installer reference guide.
Prerequisite: All other commissioning tasks are finished.
1 Start the brine pump test run and leave it on for at least
3 seconds.
Result: A 60‑second timer starts counting down.
2 Stop the brine pump test run before the timer has finished.
Result: A 30‑second timer starts counting down.
3 Start the brine pump test run again and leave it on for at least
3 seconds.
4 Stop it before the timer has finished.
Result: 10‑day brine pump operation switches (OFF→ON or
ON→OFF).

(±30 min). To stop it manually, press , select OK and press .
INFORMATION
If 2 user interfaces are present, you can start a test run
from both user interfaces.
▪ The user interface used to start the test run displays a
status screen.
▪ The other user interface displays a "busy" screen. You
cannot use the user interface as long as the "busy"
screen is shown.
6.2.5 To perform an actuator test run
Prerequisite: Make sure that the leaving water temperature home
page, room temperature home page, and domestic hot water home
page are turned OFF.
1 Set the user permission level to Installer. See "To set the user
permission level to Installer" on page 14 .
2 Make sure the room temperature control, the leaving water
temperature control and the domestic hot water control are
turned OFF via the user interface.

finished. To stop it manually, press , select OK and press .
INFORMATION
If the brine pump test run is activated as part of the 10‑day
