Step 2: Fastening
Align the centre of the pipes and tighten the screw nuts by

hand.
Tighten the screw nuts with a spanner until they click.

 Torques.
Step 3: Preventing foreign bodies from entering the
unit
Seal all pipe openings well with putty or a different type of

insulation (available separately).
 If insects or small animals enter the outdoor unit, they can
cause short circuits in the control cabinet.
Lay the pipes. To do this, cover the coupling device of the

indoor unit with insulation and fix in place with two adhe-
sive tapes.
Adequate thermal insulation is extremely important.

Putty or insulation (available separately)
CAUTION!
Never open the valves of the outdoor component.
Carry out the work from Cap. 7.2 on page 18
and Cap. 7.3 on page 20 first.

7.2 Electrical connections

7.2.1 Outdoor unit
NOTE
The DIP switches on the circuit boards in the outdoor unit
have no function. The positions of the DIP switches must
remain in their factory default and must not be changed!
Two cables must be connected on the outdoor unit:
A 'mains cable' and a 'data cable'
Both cables must be laid between the indoor and outdoor unit.
The mains cable is used to supply the outdoor unit with power
and the data cable is for communication between the outdoor
and indoor component. The VDE directives and regulations and
local conditions must be taken into account in the design and
installation of the two cables.
The fusing of the outdoor unit and the indoor unit must be ex-
ternal.
The mains cable on the 6/10 kW outdoor unit must be three-
core and be connected to the terminals L/N/PE (power supply).
For the 14 kW outdoor unit, the mains cable must be 3-core or
5-core, depending on the version (230 V or 400 V), and be con-
nected to terminals L1/N/PE or LI/L2/L3/N/PE.
 No cables with different thicknesses may be connected to
the connecting terminal. (One of the cables may come
loose during strong heat development.)
Multiple cables of the same thickness must be connected

as shown in the figure.
A shielded 2-core cable must be used as a data cable.
Connect communication terminal E/P/Q on the outdoor unit to
the J9 BUS terminals on the control module in the indoor unit
switch box.
The connections can be established as follows:
Connecting terminal P (outdoor unit) to J9 negative (-) (in-

door unit)
 Connecting terminal Q (outdoor unit) with J9 positive (+)
(indoor unit)
Connecting terminal E (outdoor unit) with J9 ground (o) (in-

door unit)
To avoid interference and distortion of the communication sig-
nal, the communication cable should not be routed directly
next to the mains cable. Create as much space as possible be-
tween the communication cable and the mains cable. The liq-
uid and gas lines should be laid in the middle and the mains and
communication cables to the sides.
