Commissioning

8.1 General

To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorised by
the manufacturer. These measures can also include an addi-
tional warranty under certain conditions (see Warranty).

8.2 Preparation

The following items must be checked prior to start-up:
All of the heat pump connections must be installed as de-

scribed in chapter 7.
The heat source system and the heating circuit must have

been filled and checked.
 Dirt traps and breathers must be inserted in the brine inlet
of the heat pump.
 All valves that could impair proper flow in the brine and
heating circuits must be open.
The heat pump manager must have been parametered for

the relevant hydraulics in accordance with its operating in-
structions.

8.3 Start-up procedure

The heat pump is started up via the heat pump manager.
ATTENTION!
The heat pump must be started up in accordance with the
installation and operating instructions of the heat pump
manager.
The overflow valve must be adjusted to the requirements of the
respective heating system. Incorrect adjustment can lead to
faulty operation and increased energy consumption. We rec-
ommend carrying out the following procedure to set the over-
flow valve correctly:
Close all of the heating circuits that may also be closed during
operation so that the most unfavourable operating state - with
respect to the water flow - is achieved. This normally means the
heating circuits of the rooms on the south and west sides of the
building. At least one heating circuit must remain open (e.g.
bathroom).
The overflow valve should be opened far enough to produce
the maximum temperature spread between the heat flow and
heat return flow listed in the following table for the current heat
source temperature. The temperature spread should be meas-
ured as close as possible to the heat pump. The heating ele-
ment of mono energy systems should be disconnected during
start-up.
