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 indoor unit connections must be installed as de-

scribed in Cap. 6.1 on page 12.
 All of the outdoor unit connections must be installed as de-
scribed in Cap. 7 on page 15.
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 settings of the heat pump manager must be adapted

to the heating system in accordance with the manager's
operating instructions.
The heating water circuit, domestic hot water cylinder and

buffer tank of the indoor unit must be completely filled and
purged.
Ensure that the condensate drain functions properly.

 The outflow from the heating water pressure relief valve
must also function correctly.
Purging the heating system:

Ensure that all heating circuits are open, purge the system
at the highest position and refill water if necessary (comply
with static minimum pressure).
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.
