General
Operative range
The heat pump is designed exclusively for the heating of
heating circuit water and domestic hot water. Considering
the application limits (see technical data), the heat pump
can be installed on new or existing heating installations.
Functioning of the brine / water heat pump
The heat pump converts the low temperature heat of the
earth to a higher temperature. Brine (a mixture of water
and antifreeze agent) is pumped through coils laid in the
earth and conducted to the evaporator of the heat pump.
The evaporator contains the liquid agent which boils
and vaporizes at low temperatures and low pressure.
The vaporizing heat is transferred from the brine. The
compressor sucks in the vaporized agent and compresses
it to achieve a higher pressure. The compressed gaseous
agent enters the condenser, where it condenses at high
pressure and high temperature. The condensation heat
is transferred to the heating circuit water with resultant
increase in temperature.
The energy transmitted to the heating circuit water
corresponds to the energy transmitted from the brine plus
the small amount of electric energy for the compressor.
Energy-saving use of the heat pump heating
installation
By choosing a heat pump heating installation, you have
acknowledged the need for environmental protection
by lower emissions and less consumption of energy. To
ensure your new heating system works as efficiently as
possible, please note the following:
The heat pump heating installation must be
correctly sized and installed.ks.
Avoid unnecessarily high flow temperatures.
The lower the flow temperature at the heating
circuit water side is, the more efficiently the heat
pump works.
The controller must be set correctly!!
Preferably open the window totally to renew the
air. Compared to constantly pivot-hung windows
opening outward, this kind of ventilation reduces the
energy consumption and saves money!

The hydraulic supply points are on the de-
vice rear:
.
All pipe connections are 2” external threads (conical pipe
threads).
To avoid structure-borne sound transmissions to the
heating system, the connection of the heat pump on
the heating circuit water side and on the heat source
side must be vibration-free.
We recommend the use of compensators (see photo
to the right).
When connecting the heating circuit water pipework,
the connection point on the heat pump must be secu-
red against torsion with a spanner in order to avoid
damage to the copper pipe on the condenser side.
Heat source supply point:
The heat source installation must be sized in accordance with the
prescriptions in the project planning manual.
Please note:
• Before filling the heat source installation, it must be rinsed
thoroughly.
• A mud flap (sieve size 1,0 mm) must be installed in front of
the heat pump input on the brine side (not delivered with the
unit)
• The water/antifreeze-mixture (brine) must be mixed tho-
roughly before filling in the heat source installation.
• The brine concentration must be at least 25%.
The heat source side should be vented by the controller before
the commissioning of the heat pump (see “system venting” under
“service>settings” in the instruction manual of the heat pump
controller).
Upon completion of the venting program, clean the mud flap
again before commissioning the heat pump.
Please ensure the minimum brine flow rate.
Motor circuit switches for the brine circulating pump are integra-
ted in the heat pump. Please find the relevant settings in the
following schedule:
Device Settings motor circuit switch
SWP 230H 1,1 - 1,6 A
SWP 330H 1,1 - 1,6 A

The hydraulic supply points are on device
rear:
.
All pipe connections are 2” external threads (conical pipe
threads).
To avoid structure-borne sound transmissions to the
heating system, the connection of the heat pump on
the heating circuit water side and on the heat source
side must be vibration-free.
We recommend the use of compensators (see photo
to the right).
When connecting the heating circuit water pipework,
the connection point on the heat pump must be secu-
red against torsion with a spanner in order to avoid
damage to the copper pipe on the condenser side.
Heating circuit water supply point:
The heating system must be flushed before connecting the
heat pump to prevent contamination inside the heating system
affecting the function of the heat pump.
On the heat pump side, flow and return must be equipped with
isolating valves to allow eventual flushing of the condenser.
The heat source installation must be sized in accordance
with the prescriptions in the project planning manual.
Please note:
• Ensure the minimum heating circuit water flow rate.
The minimum heating circuit water flow rate depends on the
heating output of the heat pump; for further details see the
technical data sheets of the heat pumps.
• The spread between flow and return must be < 10K
• Buffer storage
A series buffer storage is needed to ensure a minimum run-
ning time of the heat pump and to limit the number of heat
pump timings.
Size of the buffer storage:
• With bivalent installations, the heat pump should never
be flown through by heating circuit water temperatures
exceeding 55°C (M-devices) or 65°C (H-devices).
• Circulating pump
The heating circuit water and sanitary water circulating
pumps must be graded.
The use of variable speed pumps is not
permitted!
• Sanitary water heating
Domestic water heating with the heating pumps takes place
with a second heating circuit run in parallel to the heating
circuit. Please note: during the installation, the return must
not be connected to the buffer storage. Water heating takes
priority, provided it has not been altered within the program-
mer.
• Sanitary water storage
For domestic hot water requirements using a heat pump, it
is vital to have special sanitary hot water storages. It is im-
portant to have a large enough heat exchanger within the
hot water tank to ensure the heating output of the heat
pump is transferred with lowest possible spread with a he-
ating circuit water flow temperature < 55°C (M-devices) or <
65°C (H-devices). The storage volume must be big enough
to ensure the required sanitary hot water quantity even du-
ring off-times by your local energy supply company..
