83053706dUK – Translation of the operating manual
ATTENTION
Connect the unit to the heating circuit according
to the hydraulic diagram for the respective
model.
“Hydraulic connection” instructions.
ATTENTION
The heat source system must be designed
according to the specifications of the planning
manual.
Planning manual and “Hydraulic connection”
documents.
NOTE:
Check to make sure that the diameters and
lengths of the pipes for the heating circuit and
the heat source are sufficiently dimensioned.
NOTE:
Circulating pumps, which pump the volume flow
through the heat pump, must be designed as
multi-stage pumps. They must at least provide
the minimum throughput rate required for your
model.
In the case of heat source pumps, the viscosity of
the brine liquid must also be taken into account!
Overview “Technical data / scope of delivery”,
“Heat circuit” and “Heat source” sections.
ATTENTION
The hydraulic system must be equipped with
a buffer tank, the required volume of which
depends on the model of your unit.
ATTENTION
When installing the connections, always secure
the connections on the unit against twisting, in
order to prevent damage to the components
inside the unit.
Installation of the hydraulic
connections
BUFFER TANK
The hydraulic connection of the heat pump requires a
buffer tank in the heating circuit. The required volume
of the buffer tank is calculated based on the following
formula:
V
Buffer tank
=
minimum flow rate of heat circuit volume flow / hour

For the minimum flow rate of the heat circuit
volume flow, see overview “Technical data/
Scope of delivery”, “Heating circuit” section.
DOMESTIC WATER HEATING
The domestic water heating with the heat pump requires
an additional hot water circuit, parallel to the heating
circuit. When installing, make sure that the domestic hot
water charge is not fed through the buffer tank of the
heating circuit.
“Hydraulic connection” instructions.
DOMESTIC HOT WATER TANK
If the heat pump is to be used for domestic water
heating, you must integrate special domestic hot water
tanks in the heat pump system. Choose a storage volume
so that the required quantity of hot water is available
even during a power cut.
NOTE:
The heat exchanger surface of the domestic hot
water tank must be dimensioned so that the
heating capacity of the heat pump is transferred
with minimum spread.
We offer a variety of domestic hot water tanks for you
to choose from. They are optimised for use with your
heat pump.
