The ow direction of the hot water system must also be
rotated via the switching valve during cooling.

Circulating pumps
ATTENTION
Always note the model.
Do not use unregulated circulating pumps.
Circulating pumps and domestic hot water cir-
culation pumps must be multi-stage, regulated
pumps.
Water heating
Water heating with the heat pump requires an addition-
al hot water circuit, parallel to the heating circuit. Make
sure that the heating water charge is not channelled
through the buffer tank of the heating circuit.
“Hydraulic connection” instructions.
Hot-water tank
If the heat pump will be used for heating hot water, you
must integrate special hot-water tanks in the heat pump
system. The storage volume must be sufcient so that
the required hot water quantity is available even during
a power cut.
Install the condensate water hose in the unit so that
there is no contact with refrigerant pipes.
Make sure that frost-free condensate discharge is
ensured.

Heat pump planning manual.
Seal empty pipes on unit side.
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 sufcient 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.
Pressure relief
Equip the heating circuit in accordance with local
standards and directives with a safety valve and an
expansion tank.
Also install lling and emptying devices, shut-off devices
and non-return valves in the heating circuit.
Separating buffer tank
The hydraulic integration of the heat pump is only
permissible with a separating buffer tank (Isolation
against vapour diffusion).
