1.1 Important Information
CAUTION!
The well water must meet the required
water quality standards.
CAUTION!
The heat pump is not attached to the
wooden pallet.
CAUTION!
The heat pump must not be tilted
more than max. 45 ° (in either direction).
CAUTION!
Do not lift unit by the holes in the panel
assemblies!
CAUTION!
Flush the heating system prior to
connecting the heat pump.
CAUTION!
When connecting the load lines be
sure to observe the clockwise phase sequence.
1.2 Legal Provisions and Directives
This heat pump is in compliance with all relevant
DIN/VDE regulations and EU directives. These
are described in more detail in the EC Declaration
of Conformity.
The electrical connection of the heat pump must
be performed according to and conforming with
all relevant VDE, EN and IEC standards. Beyond
that, all connection requirements of the local
electrical utility company have to be observed.
The heat pump is to be plumbed into the heat
source and heating systems in accordance with
all relevant regulations.
1.3 Energy-Efficient Use of the Heat
Pump
By operating this heat pump, you contribute to the
protection of the environment. An important
prerequisite for energy-efficient operation is the
careful sizing of the heating system and the heat
source. 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!
Commissioning of the heat pump
must be performed in accordance with the
operating instructions of the heat pump
controller.
CAUTION!
Any work on the heat pump may be
performed by an authorised and competent
customer service only.
CAUTION!
Before opening the unit, all electrical
circuits must be disconnected from the power
supply.

PURPOSE OF HEAT PUMP
BASELINE UNIT
2
PURPOSE OF THE HEAT
PUMP
3
BASELINE UNIT
The water-to-water heat pump is designed for
use in existing or newly built heating systems.
Water, which can be supplied from wells, or the
like, is used as the heat carrier.
The baseline unit consists of a heat pump, ready
for connection, for indoor installation, complete with
housing, control panel and integrated controller.
The refrigeration cycle contains the refrigerant
R407C. The refrigerant is CFC-free, non-ozone
depleting and non-combustible.
To prevent any corrosion damage to the evaporator, the well water must be evaluated in
accordance with DIN 50930 as to the corrosion
risk of metallic materials.
All components required for the operation of the
heat pump are integrated in the control panel.
The power feed for the load and control current
must be field-installed by the customer.
More details are contained in the Project Planning
and Installation Manual for heat pumps for
heating purposes.
The supply lead of the well pump (to be provided
by the customer) must be connected to the control
panel. When so doing, check whether the capacity
of the factory-installed motor protecting device is
adequate for the field-installed pump.
2.1 Application
CAUTION!
The well water must meet the established water quality standards.
1
2
2.2 Principle of Operation
A well pump conveys the water into the evaporator
of the heat pump where it gives off heat to the
refrigerant in the refrigeration cycle.
The refrigerant is then "sucked 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, but most of the generated heat is
transferred to the refrigerant as well.
Subsequently, the refrigerant is passed through
the condenser where it transfers its heat energy
to the heating water.
3
Based on the thermostat setting, the heating
water is thus heated to up to 55 °C.

TRANSPORT
MOUNTING
4
TRANSPORT
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.
CAUTION!
The heat pump is not secured to the
wooden pallet.
5
INSTALLATION
5.1 General Information
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 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.
1m
1m
1m
CAUTION!
The heat pump must not be tilted
more than max. 45° (in either direction).
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. Any ordinary pipe can be used as a carrying
aid.
CAUTION!
Do not lift unit using the holes provided
in the panel assemblies!
5.2 Sound Emissions
The heat pump offers silent operation due to efficient
sound insulation. To prevent noise transmission to
the foundation, a suitable, sound dampening rubber
mat should be placed underneath the base frame
of the heat pump.
The transmission of noise to the heating system
is prevented by pressure hoses already integrated
into the heat pump.

MOUNTING
6.1 General
The following connections need to be established
on the heat pump:
- supply/return flow of well system
- supply/return flow of heating system
- power supply
CAUTION!
The well water must meet the required
water quality standard.
6.4 Electrical Connection
The following electrical connections must be
established on the heat pump.
-
Connection of the control wire to the control panel
of the heat pump via terminal X1: L/N/PE.
-
Connection of the load wire to the control panel
of the heat pump via terminal X5: L1/L2/L3/PE.
-
Connection of the well pump load wire to the
control panel of the heat pump via terminal
X5: L11/L21/L31/PE.
-
Connection of the well pump (to be provided
by the customer) to the control panel of the
heat pump via terminal X1: PE and pump
contactor K2: 2/4/6.
6.2 Heating-Side Connection
CAUTION!
The heating system must be flushed
prior to connecting the heat pump.
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, deaerated and pressure-tested.
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.
Frost protection for installations prone to frost
Provided the controllers and 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.
6.3 Heat Source-Side Connection
The following procedure must be observed when
making the connection:
When connecting the load wire of the well pump it
must be ensured that the power supply for these
terminals cannot be disconnected by the tariff
contactor in order to ensure the cutout delay of
the well pump.
All electrical components required for the
operation of the heat pump are located on the
control panel.
For detailed instructions concerning the connection
and functioning of the heat pump controller refer to
the operating manual supplied with the controller..
An all-pole disconnecting-device with a contactgap of at least 3 mm (e.g. utility company disable
contactor or power contactor) as well as a 3-pole
circuit breaker with simultaneous tripping of all
external conductors. 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
electrical utility company as well as all applicable
provisions. Details on the power consumption of
the heat pump are contained on the product
information sheet and the rating plate. The terminals
are designed for a conductor cross-section of
max. 10 mm˝.
CAUTION!
When connecting the load line, make
sure that the phase sequence is correct (if the
phase sequence is not correct the heat pump will
not perform properly and generate abnormal
noise).
Connect the well lines to the flow and return pipes
of the heat pump.

COMMISSIONING
CARE/CLEANING
7
COMMISSIONING
Any malfunctions occurring during operation are
displayed on the heat pump controller and can be
corrected as described in the operating manual of
the heat pump controller.
7.1 General
To ensure proper commissioning it should be
carried out by an after-sales service authorized by
the manufacturer. Only then can an extended
warranty period of 3 years in total be granted (cf.
Warranty service).
7.2 Preparation
Prior to commissioning, the following items need to
be checked:
- All connections of the heat pump must have been
made as described in Chapter 6.
- The heat source system and the heating circuit
must have been filled and tested.
- In the well and heating circuits all valves that
could impair the proper heating water 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.
7.3 Procedure
The start-up of the heat pump is effected via the
heat pump controller.
CAUTION!
Commissioning of the heat pump
must be performed in accordance with the
mounting and operating manual of the heat
pump controller.
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 electric power
consumption. To correctly set the overflow valve, the
following procedure is re-commended:
a) Open all heating circuits and close the overflow
valve. Determine the resulting temperature
difference between supply and return flow.
b) Close all of the heating circuits that may also be
closed during operation (depending on the type
of heat pump usage) so that the most unfavourable operating state - with respect to the water
flow rate - is achieved.
8
CARE/CLEANING
8.1 Care
The heat pump is maintenance-free. To prevent
malfunctions due to sediments in the heat exchangers, care must be taken that no impurities can
enter the heat source system and heating installation. In the event that operating malfunctions due to
contamination occur nevertheless, the system
should be cleaned as described below.
8.2 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.
In the case of severe contamination leading to a
reduction of the performance of the condenser in the
heat pump, the system must be cleaned by a heating
technician.
According to 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. To prevent any damage
caused by cleaning agent residues that may be
present in the system it is important that the system
be thoroughly flushed using appropriate neutralising
agents.
The 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!

CARE/CLEANING
MALFUNCTIONS/TROUBLESHOOTING
DECOMMISSIONING
CAUTION!
Caution - Heating Technicians !
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
proper 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.
8.3 Cleaning of Heat Source Side
A strainer is fitted in the heat source inlet of the
heat pump in order to protect the evaporator
against contamination. Initially, the filter screen
of the strainer should be cleaned at relatively short
intervals. Once there is less contamination, the
intervals can be extended accordingly.
9
MALFUNCTIONS/
TROUBLESHOOTING
This heat pump is a quality product and designed
for trouble-free operation. In the event that a
malfunction occurs nevertheless, you will be able
to correct the problem easily yourself in the
majority of cases. Simply consult the Malfunctions
and Troubleshooting table in the operating
manual of the controller.
Additional malfunctions can be interrogated at the
heat pump controller.
If the problem cannot be corrected by the user,
please contact the after-sales service in charge
(see Warranty Certificate).
CAUTION!
Any work on the heat pump may only
be performed by an authorized and qualified aftersales service.
CAUTION!
Prior to opening the unit, all of its
electric circuits must be disconnected from the
power source.
8.4 Water Quality Requirements
To prevent any so-called "ochredisation" (deposition of iron and manganese) of the heat pump
system from occurring, the ground water must be
free of all substances that could result in mineral
deposits, and the limit values for IRON (< 0.2 mg/
l) and MANGANESE (< 0,1 mg/l) must be complied
with.
The use of surface water or saline water bodies
is not permitted. Consult your local waterworks
for some general information about any possible
ground water usage. Water analyses are prepared
by laboratories specialising in water technology.
No water analysis with respect to any corrosion
of the evaporator is required if the average annual
ground water temperature is not in excess of
13 °C. In this case, only the limit values for iron
and manganese must be met ("ochredisation"
risk).
10
DECOMMISSIONING
10.1 Placing Out of Service in
Summer
Placing the heat pump out of service in summer can
be effected by switching the heat pump controller to
the "Summer" operating mode.
10.2 End-of-Life Decommissioning/
Disposal
Before removing the heat pump, disconnect the
machine from the power supply and close all
valves. Environment-relevant requirements regarding the recovery, recycling and disposal of
service fuels and components in accordance with
all relevant standards must be adhered to. In this
context, particular attention must be paid to the
proper disposal of refrigerants and refrigeration
oils.
