1.3 Energy-Efficient Use of the Heat
Pump
in the heat source inlet of the heat pump in order
to protect the evaporator against contamina-
tion.
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 brine must contain 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 observed when connecting the load
line.
CAUTION!
CAUTION!
Commissioning of the heat pump
must be performed in accordance with the
mounting and operating manual of the heat
pump controller.

PURPOSE OF HEAT PUMP
BASELINE UNIT
PURPOSE OF THE HEAT
BASELINE UNIT
PUMP
2 3
The baseline unit consists of a heat pump, ready for
connection, for indoor installation, complete with sheet
metal cabinet, control panel and integrated controller.
The refrigeration cycle contains the refrigerant R407C.
Refrigerant R407C 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 on the control panel. The power
feed for the load and control current must be field-
installed by the customer.
The supply lead of the brine pump (to be provided by
the customer) must be connected to the control
panel. When so doing, a motor protecting device is
to be installed, if required.
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.
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 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.

ACCESSORIES
TRANSPORT
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.
ACCESSORIES
4.1 Brine Manifold
4 5
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.
CAUTION!
The heat pump is not secured to the
wooden pallet.
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. A commercially available pipe can be used
as a carrying aid.
CAUTION!
Do not use the holes in the panel
assemblies for lifting the unit!

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 heating system
- power supply
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.
7.2 Connection on Heating Side
The heating system must be flushed
CAUTION!
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.
1 m
1 m
Once the installation on the heating side has been
completed, the heating system must be filled, de-
aerated and pressure-tested.
1 m
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. To prevent noise transmission to
the foundation, a suitable, sound dampening rubber
mat should be placed underneath the base frame
of the heat pump.
Any sound transmission to the heating systems is
prevented by means of flexible pressure tubing
already integrated into the heat pump.
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.

MOUNTING
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.
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.
CAUTION!
The clockwise phase sequence
must be observed when connecting the load line
(the heat pump will deliver no output and will be
very noisy when the phase sequence is in-
correct).
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.
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 be 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 the control panel
of the heat pump via terminals X1: L/N/PE.
Connection of the load wire to the control panel
of the heat pump via terminals X5: L1/L2/L3/PE.
Connection of the brine 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 (.. 5-17CS), or motor protection F7: 2/4/
6 (.. 21CS).
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.

COMMISSIONING
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 unfa-
vourable operating state - with respect to the water
flow rate - is achieved.
c) In this operating state open the overflow valve
until approximately the same temperature
difference exists that was measured under a)
when the overflow valve was closed and the
heating circuits open.
COMMISSIONING
8
8.1 General Information
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).
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.
8.2 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 7.
The heat source system and the heating circuit
must have been filled and checked.
The strainer must have been fitted in the sole
inlet of the heat pump.
In the brine 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.
8.3 Commissioning 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 elec-
tric power consumption. To correctly set the overflow
valve, the following procedure is recommended:
a) Open all heating circuits and close the overflow
valve. Determine the resulting temperature
difference between supply and return flow.

CARE/CLEANING
CARE/CLEANING
9.1 Care
CAUTION!
Caution - Heating Technicians !
9
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 waters 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.
The heat pump is maintenance-free. To prevent
malfunctions due to sediments in the heat ex-
changers, care must be taken that no impurities can
enter the heat source system and heating installa-
tion. In the event that operating malfunctions due to
contamination occur nevertheless, the system
should be cleaned as described below.
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.
9.3 Cleaning of Heat Source Side
The supplied strainer is to be install-
CAUTION!
ed in the heat source inlet of the heat pump in
order to protect the evaporator against conta-
mination.
Also residues of lubricating and sealing agents may
contaminate the heating water.
In the case of severe contaminations leading to a
reduction of the performance of the condenser in
the heat pump, the system must be cleaned by a
heating technician.
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.
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!
