Commissioning
8.1 General Information
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 guarantee (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.
The heat source system and the heating circuit must have
been filled and checked.
The dirt trap 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.
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 hydraulic network, dirt separators or magnetite separa-
tors must be installed on-site before the medium enters
the heat pump. The maintenance intervals must be defined
by a suitably qualified person.
8.3 Commissioning procedure
The heat pump is commissioned via the heat pump manager.
CAUTION!
Start-up must be performed in accordance with the
installation and operating instructions of the heat pump
manager.
