16.5 Installation / connection to
heating circuit
IMPORTANT
Dirt and deposits in the (existing) hydraulic
system can cause damage to the heat pump.
► Ensure that a sludge separator is installed in the
hydraulic system.
► Rinse the hydraulic system thoroughly prior to es -
tablishing the hydraulic connection of the heat
pump.
IMPORTANT
Connect the unit to the heating circuit accord -
ing to the hydraulic diagram for the respec -
tive model.

“Hydraulic connection” instructions
NOTE
Check to make sure that the diameters and
lengths of the pipes for the heating circuit (in -
cluding the ground lead between the heat
pump and the building!) are sufficiently di -
mensioned.
NOTE
Circulating pumps must be multi-stage. They
must be able to deliver at least the minimum
hot water flow rate required for your model.

“Technical data / scope of delivery“, from
page 22, “Heating circuit” section
IMPORTANT
The hydraulic system must be equipped with
a buffer tank, the required volume of which
depends on the model of your unit.

page 22, “Heating circuit” section, “buffer tank”
IMPORTANT
When installing the connections, always se -
cure the connections on the unit from twist -
ing, in order to prevent damage to the copper
pipes in the interior of the unit.
1. Install the outside pipes of the heating circuit be -
neath the frost line.
2. Install shut-off devices for the hot water outflow
(forward flow) and hot water inflow (return flow) on
the heat pump side.
NOTE
During installation of the shut-off devices, the
liquefier of the heat pump can be rinsed, if
necessary.
3. Connect the unit to the pipes of the heating circuit
via vibration decouplers.
They must be installed in order to prevent damage
from vibrations to the pipes.
NOTE
If an existing system is being replaced, the old vi -
bration decoupling may not be reused.
Vibration decouplers are available as accessories.
1 Hot water inflow (return flow) connection
2 Hot water outflow (forward flow) connection
3 Condensate water hose
4. Install the condensate water hose in the unit so
that there is no contact with refrigerant pipes.
5. Make sure that frost-free condensate discharge is
ensured.

tive unit model

6. Seal empty pipes on unit side.
16.6 Condensate discharge
The condensate from the air must be discharged frost-
free via a condensate pipe with a minimum diameter of
50 mm. For underlying surfaces that are permeable to
water, it is sufficient to insert the condensate pipe ver -
tically at least 90 cm into the ground. If the condensate
is discharged into drainage or sewage systems, install
frost-free with gradient.
Discharge of the condensate into the sewage system
is permitted only via a funnel siphon, which must be
accessible at all times.
