1.3 Energy-Efficient Use of the Heat
connecting the heat pump.
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.
CAUTION!
The supplied strainer is to be fitted in
the heat source inlet of the heat pump to protect
the evaporator against contamination.
CAUTION!
The brine solution must consist of at
least 25 % of a frost and corrosion protection
agent on a monoethylene glycol or propylene
glycol basis.
CAUTION!
The clockwise phase sequence must
be ensured when connecting the load lines.
CAUTION!
Commissioning of the heat pump must
be performed in accordance with the installation
and operating manual of the heat pump controller.
CAUTION!
All electrical circuits must be dis-
connected from the power supply prior to opening
the unit.

3.1 Baseline Unit
The baseline unit consists of a heat pump, ready
for connection, for indoor installation, complete with
sheet metal cabinet, control box and integrated
controller. The refrigeration cycle contains the
refrigerant R404A. Refrigerant R404A is CFC-free,
non-ozone depleting and non-combustible.
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.
All components required for the operation of the heat
pump are located in the control box. A sensor for
the external wall temperature including mounting
hardware as well as a strainer are supplied with
the heat pump. The voltage supply for the load
and control current must be provided by the
customer.
2.2 Principle of Operation
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.
The control wire of the brine pump (to be provided
by the customer) is to be connected to the control
box. When so doing, a motor protecting device is
to be installed, if required.
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.
The collector loops including the 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-
1

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.

6.1 General Information
7.1 General Information
As a rule, the unit must be installed indoors on a
level, smooth and horizontal surface. The entire base
frame should make full 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 estab-
lished on the heat pump:
- supply/return flow of the brine system
- supply/return flow of the heating system
- power supply
The heat pump should be installed to allow easy
maintenance/service access. This is ensured if
a clearance of approx. 1 m in front of the heat
pump is maintained.
7.2 Connection on Heating Side
CAUTION!
The heating system must be flushed
prior to connecting the heat pump.
0,5m
Before completing 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, and the like. Any accumulation of deposits
in the condenser may result in a total failure of the
heat pump.
Once the installation on the heating side has been
completed, the heating system must be filled, de-
aerated and pressure-tested.
1m
The sensor supplied loose in the control box must
be fitted as shown in the block diagram.
Heating water minimum flow rate
The heating water minimum flow rate through the
heat pump must be assured in all operating states
of the heating system. This can be accomplished,
for example, by installing a differential pressure-free
manifold or an overflow valve. The procedure for
setting an overflow valve is described in the Chapter
Commissioning.
6.2 Sound Emissions
The heat pump offers silent operation due to efficient
sound insulation. Any sound transmission to the
foundation or the heating system can be largely
prevented by internal sound decoupling measures.
Frost protection for installations prone to frost
Provided the controller and heating circulating
pumps are ready for operation, the frost protection
feature of the controller is active. If the heat pump
is taken out of service or in the event of a power
failure, the system has to be drained. In heat pump
installations where a power failure cannot be readily
detected (holiday house), the heating circuit must
contain a suitable antifreeze product.

MOUNTING
For more detailed instructions concerning the
connection and functioning of the heat pump
controller (e.g. the supplied external wall sensor)
please refer to the enclosed operating manual of
the controller.
7.3 Connection on Heat Source
Side
The following procedure must be observed when
making the connection:
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 conductors 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 35 mm˝.
Connect the brine line to the flow and return pipe
of the heat pump.
CAUTION!
The supplied strainer must be fitted
in the heat source inlet of the heat pump in order
to protect the evaporator against the ingress
of impurities.
In addition, a powerful vent must be installed at
the highest point of the heat source system. The
hydraulic plumbing diagram must be observed
here.
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.
CAUTION!
The clockwise phase sequence must
be observed when connecting the load lines (the
heat pump will deliver no output and will be very
noisy when the phase sequence is incorrect).
Only antifreeze products on the basis of mono-
ethylene glycol or propylene glycol may be used.
The heat source system must be vented (de-
aerated) and checked for leaks.
CAUTION!
The brine solution must contain at
least 25 % of an antifreeze and corrosion
protection agent on a monoethylene glycol or
propylene glycol basis.
7.4 Electrical Connection
The following electrical connections must be
established on the heat pump:
- Connection of the control wire to terminals X1:
L/N/PE in the control box of the heat pump.
The power cable must be run through the guide
tubes, inserted into the side of the control box and
secured by means of the strain relief.
- Connection of the load wire to terminals X5:
L1/L2/L3/PE in the control box of the heat pump.
- The control of the brine pump is effected via the
controller N1/J12/N03/N + PE (max. 200 W), or
a pump contactor connected to these terminals
(without PE). If a motor protective switch is used,
the auxiliary contact (NC contact) needs to be
connected to N1/J5/ID5 and X2, instead of the
wire jumper which must be removed.
All electrical components required for the operation
of the heat pump are located in the control box.

COMMISSIONING
8.3 Commissioning Procedure
COMMISSIONING
The start-up of the heat pump is effected via the
heat pump controller.
88.1 General Information
To ensure proper commissioning it should be carried
out by a customer service authorised by the manu-
facturer. Only then can an extended warranty period
CAUTION!
Commissioning is to be effected in
accordance with the installation and operating
manual of the heat pump controller.
of 3 years in total be granted (cf. Warranty service).
Where an overflow valve is fitted to assure the
minimum heating water flow rate, the valve must be
set in accordance with the requirements of the
heating installation. An incorrect setting may result
in various error symptoms and an increased elec-
tric power consumption. To correctly set the overflow
valve, the following procedure is recommended:
8.2 Preparatory Steps
Prior to commissioning, the following items need
to be checked:
-
-
-
-
-
All connections of the heat pump must have
been made as described in Chapter 7.
The heat source system and the heating circuit
must have been filled and checked.
Close all of the heating circuits which may also be
closed during operation (depending on the type of
heat pump usage) so that the least favourable
operating state - with respect to the water flow rate -
is achieved. Normally, these heating circuits are
those of the rooms located on the south and west
sides of buildings. At least one heating circuit must
remain open (e.g. bathroom).
The strainer must have been fitted in the sole
inlet of the heat pump.
In the brine and heating circuits all valves that
might impair the proper flow must be open.
The settings of the heat pump controller must
be adapted to the heating installation in
accordance with the instructions contained in
the controller's operating manual.
The overflow valve is to be opened to such an extent
that based on the current heat source temperature
the maximum temperature difference between
heating supply and return flow temperature is
obtained, as indicated in the table below. The
temperature difference should be measured as
closely to the heat pump as possible. In mono-
energetic systems, the electric heating element is
to be deactivated.

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 additio-
nal oxygen from the air, which may penetrate via
valves, fittings and plastic pipes (oxygen diffu-
sion). As a preventive measure it is re-
commended that a physical water conditio-ner
such as ELYSATOR be used.
9.1 Care
The heat pump is maintenance-free. To prevent
malfunctions due to sediments in the heat
exchangers, care must be taken that no im-
purities can enter the heat source system and
the heating installation. In the event that
operating malfunctions due to contamination
occur nevertheless, the system should be
cleaned as described below.
9.3 Cleaning of Heat Source Side
9.2 Cleaning of Heating Side
The ingress of oxygen into the heating water circuit
may result in the formation of oxidation products
(rust). It is therefore important - in particular with
respect to the piping of underfloor heating systems
- that the installation is executed in a diffusion-
proof manner. Also residues of lubricating
and sealing agents may contaminate the
heating water.
CAUTION!
The supplied strainer is to be install-
ed in the heat source inlet of the heat pump in
order to protect the evaporator against conta-
mination.
The filter screen of the strainer should be cleaned
one day after commissioning, thereafter every week.
If no more contamination can be noticed any more,
the strainer filter can be removed in order to reduce
pressure losses.
In the case of severe contamination leading to a
reduction in the performance of the condenser in
the heat pump, the system must be cleaned by a
heating technician.
Based on current knowledge, we recommend
cleaning with a 5% phosphoric acid solution or, in
the case that cleaning needs to be performed more
frequently, with a 5% formic acid solution.
In either case, the cleaning fluid should be at room
temperature. It is recommended that the heat
exchanger be cleaned in the direction opposite to
the normal flow direction.
To prevent acidic cleaning agents from entering
the circuit of the heating installation we recommend
that the flushing device be fitted directly to the supply
and return lines of the condenser of the heat pump.
Thereafter the system must be thoroughly
flushed using appropriate neutralising agents
in order to prevent any damage caused by
cleaning agent residues that may still be
present in the system.
All acids must be used with great care, all relevant
regulations of the employers' liability insurance
associations must be adhered to.
If in doubt, contact the manufacturer of the
chemicals!
