1.1 Important Information
CAUTION!
The supplied strainer is to be fitted
1
in the heat source inlet of the heat pump
in order to protect the evaporator against
contamination.
CAUTION!
The heat pump is not secured to the
wooden pallet.
CAUTION!
Any work on the heat pump may
only be performed by authorised and qualified
customer service agents.
The heat pump must not be tilted
CAUTION!
more than max. 45° (in either direction).
1.2 Legal Provisions and Directives
CAUTION! Do not lift unit by the holes in the
panel assemblies!
This heat pump conforms to all relevant DIN/VDE
regulations and EU directives. For details refer to
the EC Declaration of Conformity in the appendix.
CAUTION! In the case of large-capacity heating
circuits, the installed expansion vessel (24
litres, 1.0 bar admission pressure) must be
supplemented by an additional vessel.
The electrical connection of the heat pump must be
performed according to and conforming with all re-
levant VDE, EN and IEC standards. Beyond that, the
connection requirements of the local utility compa-
nies have to be observed.
CAUTION! The brine solution must contain at
least 25 % of an antifreeze and corrosion
protection agent on a monoethylene glycol or
propylene glycol basis.
The heat pump is to be connected to the heat source
and heat distribution systems in accordance with all
applicable provisions.
CAUTION!
On connecting the electrical load
lines, the clockwise phase sequence must be
observed (in the case of an incorrect phase
sequence the heat pump will deliver no output
and generate a lot of noise).
1.3 Energy-Efficient Use of the Heat
Pump
By operating this heat pump you contribute to the
protection of our environment. A prerequisite for an
efficient operation is the proper design and sizing of
the heating system and the heat source system. In
particular, it is important to keep water flow
temperatures as low as possible. All energy
consumers connected should therefore be suitable
for low flow temperatures. A 1 K higher heating water
temperature corresponds to an increase in power
consumption of approx. 2.5 %. Underfloor heating
systems with flow temperatures between 30 °C and
40 °C are optimally suited for energy-efficient
operation.
Commissioning of the heat pump
CAUTION!
must be performed in accordance with the
installation and operating manual of the heat
pump controller.
Caution - Heating Contractors !
CAUTION!
Depending on the filling water quality and
quantity, in particular in the case of mixed
installations and plastic pipes, mineral deposits
(rust sludge, lime) may form, impairing the pro-
per functioning of the heating installation. A
reason for this is the water hardness and
oxygen dissolved in the filling water as well as
additional oxygen from the air, which may
penetrate via valves, fittings and plastic pipes
(oxygen diffusion). As a preventive measure it
is recommended that a physical water conditio-
ner such as ELYSATOR be used.

PURPOSE OF HEAT PUMP
BASELINE UNIT
PURPOSE OF THE HEAT
BASELINE UNIT
PUMP
2 3
The baseline unit consists of a heat pump of
compact design, ready for connection. In addition to
the control panel with integrated controller, the unit
also contains essential components of the heating
and brine circuits:
2.1Application
The brine-to-water heat pump is designed for use
in existing or newly built heating systems. Brine is
used as the heat carrier in the heat source system.
Ground coils, ground collectors or similar systems
can be used as the heat source.
- expansion vessels
- circulating pumps
- pressure relief valves
- pressure gauges
- overflow valve (heating circuit)
2.2 Principle of Operation
The refrigeration cycle contains the refrigerant
R407C. Refrigerant R407C is CFC-free, non-ozone
depleting and non-combustible.
The heat generated by the sun, wind and rain is
stored in the ground. This heat stored in the ground
is collected at low temperature by the brine circulating
in the ground collector, ground coil or similar device.
A circulating pump then conveys the warmed brine
to the evaporator of the heat pump. There, the heat
is given off to the refrigerant in the refrigeration cycle.
When so doing, the brine cools so that it can again
take up heat energy in the brine circuit.
All components required for the operation of the heat
pump are provided on the control panel. The power
feed for load and control current must be field-
installed by the customer.
The collector loops including brine manifold must
be provided by the customer.

The refrigerant, however, is drawn in by the electrically
driven compressor, is compressed and "pumped"
to a higher temperature level. The electrical power
needed to run the compressor is not lost in this
process, but most of the generated heat is trans-
ferred to the refrigerant as well.
Subsequently, the refrigerant is passed through the
condenser where it transfers its heat energy to the
heating water. Based on the thermostat setting, the
heating water is thus heated to up to 55 °C.

4.1 Brine Manifold
A lift truck is suited for transporting the unit on a level
surface. If the heat pump needs to be transported
on an uneven surface or carried up or down stairs,
carrying straps may be used for this type of transport.
These straps may be passed directly underneath
the wooden pallet.
The brine manifold ties the individual collector loops
of the heat source system into a single main line
which is connected to the heat pump. Integrated ball
valves allow individual brine circuits to be shut off for
venting purposes.
The heat pump is not secured to the

more than max. 45° (in either direction).
Where this is a legal requirement, a low-pressure
brine pressostat may be installed in the unit. In this
case, the connection provided above the brine
expansion vessel should be used.
For lifting the unit without pallet, the holes provided
in the sides of the frame should be used. The side
panel assemblies must be removed for this
purpose. A commercially available pipe can be used
as a carrying aid.

INSTALLATION
MOUNTING
INSTALLATION
6.1 General Information
MOUNTING
6 7
7.1 General
As a rule, the unit must be installed indoors on a
level, smooth and horizontal surface. The entire base
frame should thereby make close contact with the
surface in order to ensure adequate sound
insulation. Failing this, additional sound insulation
measures may become necessary.
The following connections need to be established on
the heat pump:
- supply/return flow of the brine system
- supply/return flow of the space heating and
water heating system
- common return of space heating and water
heating system
The heat pump should be located to allow safe and
easy maintenance/service access. This is ensured
if a clearance of approx. 1 m in front of and to each
side of the heat pump is maintained.
- return, overflow valve
- connection for additional expansion vessel
(as required)
- drain lines of overflow valves
- condensate drain
- power supply
7.2 Heating-Side Connection
The heat pump features separate outlets for the space
heating and water heating circuit.
In cases where the heat pump has no water heating
mode, the hot water outlet has to be permanently
sealed.
Prior to establishing the heat pump connections on
the heating water side, the heating installation must
be flushed in order to remove any impurities that
may be present , as well as residues of sealing
material, or the like. Any accumulation of deposits in
the condenser may result in a total failure of the heat
pump.
6.2 Sound Emissions
The heat pump offers silent operation due to efficient
sound insulation. Noise transmission to the
foundation or the heating system is largely prevented
by internal decoupling measures.
In systems equipped with heating water flow shut-
off devices such as radiator or thermostat valves, an
overflow valve is installed. This assures a minimum
heating water flow through the heat pump and
prevents any malfunctions for occurring.
Once the installation on the heating side has been
completed, the heating system must be filled,
deaerated and pressure-tested.
Frost Protection for Installations Prone to Frost
Provided the controller and the heating circulating
pumps are ready for operation, the frost protection
function of the controller is always activated. If the
heat pump is taken out of service or in the event of a
power failure, the system must be drained. In heat

MOUNTING
pump installations where a power failure cannot
readily be detected (e.g. holiday houses), the heating
circuit must contain a suitable antifreeze product.
7.4 Electrical Connection
The following electrical connections must be
established on the heat pump.
The integrated expansion vessel has a capacity of
-

with a heated living space floor area of up to 200 m .
-
Connection of the control voltage wire to the
control panel of the heat pump.
The planner of the heating system should verify that
the capacity of the expansion vessel is adequate. An
additional expansion vessel may have to be
installed, if required (as per DIN 4751 Part 1). Charts
in manufacturer catalogues facilitate the proper
selection of the proper size according to the amount
of water in the system.
All electrical components required for the operation
of the heat pump are located on the control panel..
For detailed instructions concerning the connection
of external components and the operation of the heat
pump controller refer to the heat pump terminal dia-
gram and the operating manual of the controller.
With large-capacity heating circuits,
CAUTION!
Connection of the load wire to the control panel via
the installed expansion vessel (24 litres, 1.0 bar
admission pressure) must be supplemented by
an additional vessel.
terminals X1: L1/L2/L3/PE.
An all-pole disconnecting device with a contact gap
of at least 3 mm (e.g. utility company disable contac-
tor or power contactor) as well as a 3-pole circuit
breaker with simultaneous tripping of all external
conductors must be provided . The required cross-
sectional area of the conductor is to be selected
according to the power consumption of the heat
pump, the technical connection requirements of the
relevant utility company and all applicable regula-
tions. Power consumption data of the heat pump is
provided in the product literature and on the
nameplate. The terminals are designed for a max.
conductor cross-section of 10 mm˝.
7.3 Connection on Heat Source Side
The following procedure must be observed when
making the connection:
Connect the brine line to the flow and return pipe
of the heat pump. The supplied strainer and vent
must be field-installed in the brine inlet of the heat
pump.
The powerful vent must be installed at the highest
point of the heat source system
The hydraulic block schematic must be taken into
account when so doing.
CAUTION!
The clockwise phase sequence
must be observed when connecting the electric
load lines (in the case of an incorrect phase
sequence the heat pump will deliver no output
and generate a lot of noise).
The brine liquid must be produced prior to charging
the system. The brine concentration must be at least
25 %. Freeze protection down to -14 °C can thus be
ensured.
Connection of the control voltage wire is effected via
Only antifreeze agents on a monoethylene glycol or
terminals X1: L/N/PE.
propylene glycol basis are to be used.
If a more powerful brine pump is required than the
one integrated, a motor contactor and an appropriate
motor protecting switch need to be installed. The
contactor must be connected to the terminals of the
internal brine pump (controller terminals J12/N03
and X1-N). The power supply of the larger pump
must be provided by the mains supply.
The heat source system has to be vented and leak-
tested.
CAUTION!
The brine solution must contain at
least 25 % of an antifreeze and corrosion protection
agent on a monoethylene glycol or propylene glycol
basis.
