8.2.2 Indoor component
Two supply cables must be connected to the indoor compo-
nent: The power supply to the heat pump and the control volt-
age for the integrated heat pump manager (see Appendix
Chapter 3.3). (Load: 3~; 1x 5-core; control: 1~; 1x three-core)
The VDE directives and regulations and local conditions must
be taken into account in the design and installation of the ca-
bles.
Only with the heat pump combination with the 6 kW or 9 kW
outdoor unit can the power supply take place with two separate
supply cables (2x 1~/N/PE; 230 VAC; 50 Hz) via load distribu-
tion. Otherwise, the power supply always takes place with one
cable (3~/N/PE; 400 VAC; 50 Hz).
NOTE
The positions of the copper link cables in the terminals for the
power supply must be complied with. In factory default, the
copper link cables come connected correctly for a single
supply cable. For the 9 kW unit and when using two supply
cables, the positions of the copper link cables must be
changed (see Appendix, Load connection diagram Chap. 2.3).
The supply cable for the output section of the heat pump (up to
5-core) is fed from the electricity meter of the heat pump via
the utility blocking contactor (if required) into the heat pump
(see heat pump operating instructions for supply voltage). An
all-pole disconnecting device with a contact gap of at least 3
mm (e.g. utility company blocking contactor or power contac-
tor) as well as an all-pole circuit breaker with common tripping
for all external conductors must be installed in the power sup-
ply for the heat pump (tripping current and characteristic in
compliance with the device information).
The supply cable (1~L/N/PE~230 V, 50 Hz) for the heat pump
manager must have a continuous voltage. For this reason, it
should be tapped upstream from the utility blocking contactor
or be connected to the household current, because otherwise
important protection functions could be lost during a utility
block. The correct control voltage must be ensured according
to the general information leaflet/rating plate.
The utility blocking contactor (K22) with 3 main contacts (1/3/
5 // 2/4/6) and an auxiliary contact (NO contact 13/14) should
be dimensioned according to the heat pump output and must
be supplied by the customer. The NO contact of the utility
blocking contactor (13/14) is looped from terminal strip X3/G
to connector terminal N1-J5/ID3. CAUTION! Extra-low volt-
age!
The power supply must be connected to terminal strip X1 and
the control voltage to terminal X2 in the indoor component.
For detailed instructions on how to connect the external com-
ponents as well as how the heat pump manager functions,
please refer to the device connection diagram and the operat-
ing instructions supplied with the heat pump manager.
In factory default, the 2nd heat generator is connected with a 6
kW heat output. To reduce the output to 4 kW or 2 kW, one or
both of the two copper link cables must be removed from ter-
minal X7 (see circuit diagram).
For detailed information, see circuit diagrams in the Appendix.
The electrical cables can be fed into the unit from below (in the
refrigerant connection area) or from above (a duct moulded in
PU foam is located under the cylinder cover).

8.3 Final work

Once the pipes and electric cables have been connected, the
pipes must be bent and a number of tests carried out. The leak
test must be carried out with particular care, as a refrigerant
leak results in a direct reduction in output.
Leaks are also difficult to identify once the installation is com-
plete.
8.3.1 Pipe bends
Bend the pipe by covering the connection cable and refrigerant
pipe (between the indoor and outdoor unit) with insulation and
fix the insulation in place with two adhesive tapes.
1) Fix the refrigerant pipe, mains cable and connection cable
with adhesive tape from bottom to top. Fix the bound pipe-
work along the wall.
2) Form a siphon to prevent water from entering the chamber
and electrical components.
3) Fix the pipework to the wall using clamps or similar.
Wrap the pipework in adhesive tape
1) Fix the pipes, mains cable and connection cable with adhe-
sive tape from bottom to top. If they are fixed from top to
bottom, rain could enter into the pipes or cables.
2) Fix the bound pipework along the external wall with clamps
or similar.
3) A siphon prevents water from entering the electrics.
