Commissioning

8.1 General

To ensure that commissioning is performed correctly, it should
only be carried out by an after-sales service technician author-
ised by the manufacturer. This may be a condition for an addi-
tional warranty (see "Warranty service").

8.2 Preparation

The following items must be checked prior to commissioning:

All of the heat pump connections must be installed as de-
scribed in Chapter 7.

All valves which could impair the proper flow of the heating
water in the heating circuit must be open.

The air intake and air outlet paths must be clear.

The fan must turn in the direction indicated by the arrow.

The settings of the heat pump manager must be adapted
to the heating system in accordance with the latter's op-
erating instructions.

Ensure that the condensate drain functions properly.

The hydraulic network must be flushed correctly before in-
stalling the heat pump. This includes the supply line to the
heat pump. Only when flushing is complete can the heat
pump be hydraulically integrated.

The dirt traps present as standard or included for assembly
must be inspected between 4 and 8 weeks after the heat
pump is commissioned or changes made to the heating
system and cleaned if necessary. Further maintenance in-
tervals must be scheduled depending on the level of soil-
ing, which must be defined and carried out by a suitably
qualified person.
Special notes for the integration of heat pumps in
existing systems (renovations):
The existing heat distribution network (pipe materials, connec-
tion types, etc.) and the existing heating systems (e.g. radiators,
underfloor heating, etc.) can impact the quality of the water in
existing systems. Particularly when welded steel pipes or pipes
that are not oxygen diffusion-proof are used, deposits, scaling,
silting or similar may be present that can cause damage in the
heat pump system. This can result in a total failure of the heat
pump. The following measures must be observed to avoid this:

Compliance with the water properties and water quality

Flushing of the hydraulic system

Maintenance interval of the dirt traps
If silting or ferromagnetic particles are to be expected in the hy-
draulic network, dirt separators or magnetite separators must
be installed on-site before the medium enters the heat pump.
The maintenance intervals must be defined by a suitably quali-
fied person.

8.3 Procedure

The heat pump is commissioned via the heat pump manager.
Settings should be made in compliance with the HPM's instruc-
tions.
At heating water temperatures below 7 °C, commissioning is
not possible. The water in the buffer tank must be heated with
the second heat generator to at least 18 °C.
To ensure problem-free commissioning, the following proce-
dure is to be implemented:
1) Close all consumer circuits.
2) Ensure that the heat pump has the correct water flow.
3) Select "Winter" mode on the heat pump manager.
4) In the special functions menu, start the "Commissioning"
program.
5) Wait until a return temperature of at least 25 °C has been
reached.
6) Now slowly reopen the heating circuit valves in succession
so that the heating water flow rate is constantly raised by
slightly opening the respective heating circuit. The heat-
ing water temperature in the buffer tank must not be al-
lowed to drop below 20 °C during this process. This en-
sures that the heat pump can be defrosted at any time.
7) When all heating circuits are fully open and a return tem-
perature of at least 18 °C is maintained, the commissioning
is complete.
CAUTION!
!
Operating the heat pump at low system temperatures may
cause the heat pump to break down completely.
