1.3 Energy-Efficient Use of the
Heat Pump
With the purchase of this heat pump you are helping to protect
the environment. A prerequisite for energy-efficient operation is
the correct design of the heat source system and heating (radia-
tors and circulation pump) or cooling system.
1 Please Read
Immediately
1.1 Important Information
ATTENTION!
It is particularly important for the efficient heating operation of a
heat pump to keep the temperature difference between the
heating water and the heat source as small as possible. For this
reason, it is advisable to design the heat source and heating sys-
tem very carefully. A temperature difference of approx. one
Kelvin increases the power consumption by around 2.5%.
When designing the heating system, it should be borne in mind
that special consumers such as e.g. domestic hot water prepara-
tion should also be taken into consideration and dimensioned for
low temperatures. Underfloor heating systems (panel heat-
ing) are optimally suited for heat pump use on account of the low
flow temperatures (30 °C to 40 °C).
ATTENTION!
ATTENTION!
ATTENTION!
It is important to ensure that the heat exchangers are not con-
taminated during operation because this increases the tempera-
ture difference, in turn reducing the COP.
ATTENTION!
Correct adjustment of the heat pump controller is also important
for energy-efficient use of the heat pump. Further information can
be found in the heat pump controller's operating instructions.
ATTENTION!

2 Purpose of the Heat
Pump
ATTENTION!
We recommend the installation of a suitable corrosion protection system
to prevent the formation of deposits (e.g. rust) in the condenser of the
heat pump.
2.1 Application
The air-to-water heat pump is designed for use in existing or
newly built heating systems.
ATTENTION!
It is designed exclusively for heating and cooling heating water!
In heating operation, the heat pump is suitable for mono energy
and bivalent operation down to an external temperature of -
20 °C.
ATTENTION!
Proper defrosting of the evaporator is guaranteed by maintaining
a heating water return flow temperature of more than 18 °C dur-
ing continuous operation.
1.2 Legal Regulations and
Directives
The construction and design of the heat pump complies with all
relevant EU directives, DIN/VDE regulations (see CE declaration
of conformity).
The heat pump is not designed for the increased heat consump-
tion required when a building is being dried out. The additional
heat consumption should be met using special devices provided
by the customer. If a building is to be dried out in autumn or win-
ter, we recommend installing an additional heating element
(available as an accessory).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be fulfilled. Any further
connection requirements stipulated by local utility companies
must also be observed.
In cooling operation, the heat pump is suitable for temperatures
ranging from +15 °C to +40 °C.
It can be used for silent and dynamic cooling. Minimum water
temperature +7 °C.
When connecting the heating and/or cooling system, all applica-
ble regulations must be adhered to.
ATTENTION!
The device is not suitable for operation with a frequency converter.
Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
or their inexperience or lack of knowledge, must not operate this
device without supervision or instruction by the person in charge.
Children must be supervised to ensure that they do not play with
the device.

2.2 Operating Principle
3 Scope of Delivery
Heating
3.1 Basic Device
The heat pump is of compact design and is supplied complete
with the components listed below.
Surrounding air is drawn in by the ventilator and fed via the evap-
orator (heat exchanger). The evaporator cools the air, i.e. it ex-
tracts heat from it. This extracted heat is then transferred to the
working medium (refrigerant) in the evaporator.
R404A is used as the refrigerant.
The heat is “pumped” to a higher temperature level by increasing
its pressure with the aid of an electrically driven compressor. It is
then transferred to the heating water using the liquifier (heat ex-
changer).
ꢁ
ꢀ
Domestic water can be prepared simultaneously, or separately,
via the desuperheater connected in series.
Electrical energy is used to raise the temperature of the heat in
the environment to a higher level. Because the energy extracted
from the air is transferred to the heating water, this type of device
is called an air-to-water heat pump.
The air-to-water heat pump consists of the main components
evaporator, ventilator and expansion valve, as well as the low-
noise compressor, desuperheater, liquifier and electrical control
system.
At low ambient temperatures, humidity accumulates on the evap-
orator in the form of frost reducing the transfer of heat. The evap-
orator is defrosted automatically by the heat pump as required.
Steam may be emitted from the air outlet depending on the at-
mospheric conditions.
Cooling
The functions of the evaporator and the liquifier are reversed in
the “Cooling” operating mode.
The heating water transfers its heat to the refrigerant via the liq-
uifier which is now functioning as an evaporator. The refrigerant
is pumped to a higher temperature level using the compressor.
Heat is passed on to the surrounding air via the liquifier (function-
ing as an evaporator in heating operation).

3.2 Switch Box
The switch box is located in the heat pump. It can be swung out
after removing the lower front cover and loosening the fastening
screw located in the upper right-hand corner.
4 Transport
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
The switch box contains the supply connection terminals, as well
the power contactors, the soft starter unit and the heat pump
manager.
Use a wooden pallet for transporting the heat pump to the final in-
stallation location. The basic device can be transported with a lift
truck, hand truck or by means of 3/4" pipes fed through the holes
in the base plate or frame.
3.3 Heat Pump Controller
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating or
cooling system on the basis of the external temperature, includ-
ing hot water preparation and safety systems.
The customer must install the external temperature sensor,
which is included in the scope of supply of the heat pump man-
ager together with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.
ATTENTION!
The heat pump and transport pallet are only joined by the packing film.
Before using the transport holes in the frame, it is necessary to
remove the lower side panel assemblies. This is done by loosen-
ing each of the two screws at the base and then withdrawing the
panels by unhooking them from above. Rehang the panels by
gently pushing them in an upwards direction.
Be careful not to damage any components when inserting the
pipes through the frame.

5 Set-up
6 Installation
5.1 General Information
6.1 General Information
The unit must be installed indoors on a level, smooth and hori-
zontal surface. The entire base of the frame should lie directly on
the floor to ensure a good soundproof seal. If this is not the case,
additional sound insulation measures may be necessary. If the
device is installed on top of a built-under buffer tank, a surface
that fully supports the base is required. The heat pump must be
installed so that maintenance work can be carried out without
hindrance. This can be ensured by maintaining a clearance of
1 m in front and to the left and right of the heat pump.
The following connections need to be established on the heat
pump:
„ Fresh and exhaust air
„ Flow and return flow of the heating system
„ Flow and return flow of the hot water circuit
„ Condensate outflow
„ Power supply
6.2 Air Connection
ꢄꢅꢃ P
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Only operate the heat pump with the air ducts connected.
ꢄꢅꢆꢇP
ꢈꢄꢅꢆꢇPꢉ
The glass fibre reinforced concrete air ducts offered as accesso-
ries are moisture-resistant and diffusion-free.
The sealing collar is used to seal the air ducts on the heat pump.
The air ducts are not screwed directly onto the heat pump. Only
the rubber seal comes into direct contact with the heat pump
when the system is installed correctly. This guarantees easy as-
sembly and disassembly of the heat pump and also ensures that
solid-borne sound is well insulated.
ꢂ P
Never install the device in rooms subject to high humidity. Con-
densation can form on the heat pump and air circuit if the humid-
ity exceeds 50% and the external temperature is below O °C.
If the heat pump is installed on an upper storey, the load-bearing
capacity of the ceiling should be checked. On account of the
acoustics, measures for isolating possible vibrations should also
be very carefully planned in advance as well. Installation on a
wooden floor is not recommended.
5.2 Condensed Water Pipe
Condensed water that forms during operation must be drained
off frost-free. The heat pump must be mounted on a level plane
to guarantee proper drainage. The condensed water pipe must
have a minimum diameter of 50 mm and should be fed frost-free
into a sewer. Condensate should not be discharged directly into
clearing tanks and cesspits because the aggressive vapours
could destroy the evaporator.
If another type of air duct is used, observe the external and inter-
nal dimensions as specified in the figure. Also ensure that the vi-
bration and duct insulation are adequate.
5.3 Sound
If flange-mounted air ducts are used, connecting stubs are se-
cured on the air inlet and air outlet sides of the evaporator with 4
M8 x 16 hexagon bolts in the threaded holes provided. When
doing this, ensure that both air duct stubs only touch the insula-
tion. There should be no contact with the external sheeting.
To prevent solid-borne sound from being transmitted to the heat-
ing system, we recommend connecting the heat pump to the
heating system using a flexible hose. Connect the domestic
water circuit using the same type of connection.
Installed air ducts should be sound-isolated from the heat pump
to prevent the transmission of solid-borne sound to the ducts.

6.3
Antifreeze
A method of manual drainage (see illustration) should be pro-
vided for heat pumps which are exposed to frost. The antifreeze
function of the heat pump controller is active whenever the con-
troller and the heat circulating pump are ready for operation. If
the heat pump is taken out of service or in the event of a power
failure, the system has to be drained. The heating circuit should
be operated with a suitable antifreeze if heat pump systems are
implemented in buildings where a power failure can not be de-
tected (holiday home).

6.4 Electrical Connection
The power supply and control voltage are supplied using stand-
ard cables (load: 4-core, control: 3-core).
6.3 Heating and Hot Water
Connection
The heating system connections on the heat pump have a 1" ex-
ternal thread. Use a spanner to firmly grip the transitions when
connecting the heat pump.
An all-pole disconnecting device with a contact gap of at least
3 mm (e.g. utility blocking contactor or power contactor) as well
as a 3-pole circuit breaker with common tripping for all external
conductors must be installed in the power supply (tripping current
in compliance with the Device Information).
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc. Any accumulation of deposits in the
liquifier could cause the heat pump to completely break down.
For systems in which the heating water flow can be shut off via
the radiator or thermostat valves, an overflow valve must be in-
stalled by the customer in a heating bypass downstream from the
heat pump. This ensures a minimum heating water flow rate
through the heat pump and helps to avoid faults.
Ensure that the incoming supply has a clockwise rotating field
when connecting multiphase devices L1; L2; L3.
ATTENTION!
Ensure that there is a clockwise rotating field: Operating the compressor
in the wrong rotational direction could cause damage to the compressor.
The control voltage must be protected by a 10 A fuse.
For detailed information, see Circuit Diagrams in the Appendix.
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested.
Minimum heating water flow rate
The minimum heating water 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 either a
manifold without differential pressure or an overflow valve. The
procedure for adjusting an overflow valve is described in the
Chapter Start-up.

7.2 Preparation
The following items need to be checked prior to start-up:
„ All of the heat pump connections must be established as de-
scribed in Chapter 6.
Any faults occurring during operation are also displayed on the
heat pump controller and can be corrected as described in the
operating instructions of the heat pump controller.
„ All valves that could impair the proper flow of the heating
water in the heating circuit must be open.
„ The air intake and air outlet paths must be clear.
For external temperatures below 10 °C and heating water tem-
peratures below 16 °C, the buffer tank should be heated up with
the second heat generator to at least 25 °C.
„ The ventilator must turn in the direction indicated by the ar-
row.
„ The settings of the heat pump controller must be adapted to
the heating system in accordance with the controller’s oper-
ating instructions.
Observe the following procedure to implement a smooth start-up:
1) Close all of the heating circuits.
„ Ensure the condensate outflow functions.
2) Fully open the overflow valve.
3) Use the controller to select the automatic operating mode.
7.3 Procedure
The heat pump is started up via the heat pump controller. Adjust-
ments should be made in compliance with the instructions.
4) Wait until the buffer tank has reached a temperature of at
least 25 °C.
5) Now slowly reopen the heating circuit valves in succession
so that the heating water throughput is constantly raised by
slightly opening the respective heating circuit. The heating
water temperature in the buffer tank must not be allowed to
drop below 20 °C during this process. This ensures that the
heat pump can be defrosted at any time.
If an overflow valve is fitted to maintain the minimum heating
water flow rate, the valve must be adapted to the requirements of
the heating system. Incorrect adjustment can lead to faulty oper-
ation and increased energy consumption. We recommend carry-
ing out the following procedure to correctly adjust the overflow
valve:
6) Set the minimum volume flow quantity on the overflow valve
and heat circulating pump when all heating circuits are fully
open and a heating water temperature in the buffer tank of
approx. 20 °C is maintained.
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. This normally means the heating circuits
of the rooms on the south and west sides of the building. At least
one heating circuit must remain open (e.g. bathroom).
7) New buildings have an increased heat consumption on ac-
count of the energy required to dry them out. This increased
heat consumption means that marginally dimensioned heat-
ing systems can not always achieve the desired room tem-
perature. In such cases, we recommend keeping a second
heat generator on standby during the first heating period.
The limit temperature on the heat pump controller should
also be turned up to 15 °C.
The overflow valve should be opened far enough to produce the
maximum temperature spread between the heating flow and re-
turn flow listed in the following table for the current heat source
temperature. The temperature spread should be measured as
close as possible to the heat pump. The heating element of mono
energy systems should be disconnected.

8.3 Cleaning the Air System
8 Maintenance / Cleaning
Air ducts, evaporator, ventilator and condensate outflow should
be cleaned of contamination (leaves, twigs, etc.) before each
new heating period. Do this by opening the front of the heat
pump. The bottom should be opened first followed by the top.
8.1 Maintenance
To protect the paintwork, avoid leaning anything against the de-
vice or putting objects on the device. External heat pump parts
can be wiped with a damp cloth and domestic cleaner.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
ATTENTION!
Never use cleaning agents containing sand, soda, acid or chloride as
these can damage the surfaces.
Remove and rehang the side panel assemblies as described in
Chapter 4.
To prevent faults due to sediment in the heat exchanger of the
heat pump, ensure that the heat exchanger in the heating system
can not be contaminated. We recommend protecting the evapo-
rator by installing a bird guard in the inlet duct. At least 80% of the
cross section of the grating should be open. In the event that op-
erating malfunctions due to contamination still occur, the system
should be cleaned as described below.
To prevent the evaporator and the condensate tray from being
damaged, do not use hard or sharp objects for cleaning.
9 Faults / Trouble-
Shooting
8.2 Cleaning the Heating System
This heat pump is a quality product and is designed for trouble-
free and maintenance-free operation. In the event that a fault
should occur, it will be indicated on the heat pump manager dis-
play. Simply consult the Faults and Trouble-shooting page in the
operating instructions of the heat pump manager. If you cannot
correct the fault yourself, please contact your after-sales service
technician.
The ingress of oxygen into the heating water circuit may result in
the formation of oxidation products (rust), particularly if steel
components are used. These products enter the heating system
via the valves, the circulating pumps and/or plastic pipes. It is
therefore essential - in particular with respect to the piping of un-
derfloor heating systems - that only diffusion-proof materials are
used.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
ATTENTION!
We recommend the installation of a suitable corrosion protection system
to prevent the formation of deposits (e.g. rust) in the condenser of the
heat pump.
10 Decommissioning/
Disposal
Residue from lubricants and sealants may also contaminate the
heating water.
In the case of severe contamination leading to a reduction in the
performance of the liquifier in the heat pump, the system must be
cleaned by a heating technician.
Before removing the heat pump, disconnect it from the power
source and close all valves. Observe all environmentally-relevant
requirements regarding the recovery, recycling and disposal of
materials and components in accordance with all applicable
standards. Particular attention should be paid to the proper dis-
posal of refrigerants and refrigeration oils.
According to today’s state of knowledge, we recommend using a
5 % phosphoric acid solution for cleaning purposes. However, if
cleaning needs to be performed more frequently, a 5 % formic
acid solution should be used.
In either case, the cleaning fluid should be at room temperature.
We recommend flushing the heat exchanger in the direction op-
posite to the normal flow direction.
To prevent acidic cleaning agents from entering the heating sys-
tem circuit, we recommend connecting the flushing device di-
rectly to the flow and return flow of the liquifier of the heat pump.
It is important that the system be thoroughly flushed using appro-
priate neutralising agents to prevent any damage from being
caused by cleaning agent residue remaining in the system.
Acids must be used with great care and all relevant regulations of
the employers’ liability insurance associations must be adhered
to.
If in doubt, contact the manufacturer of the chemicals!
