Start-up

8.1 General Information

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 need to be checked prior to start-up:
The heat pump must be fully connected, as described 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 be adapted to the heating

system in accordance with the controller's operating in-
structions.
 Ensure the condensate outflow functions.
The outflows of the brine and heating water pressure relief

valves must not be impaired.

8.3 Start-up Procedure

The heat pump is started up via the heat pump manager.
CAUTION!
The heat pump must be started up in accordance with the
installation and operating instructions of the heat pump
manager.
The performance level of the circulating pump must be
adapted to the respective heating system.
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 correctly ad-
just the overflow valve:
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 rate - 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 heating flow
and return flow listed in the table below 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.
