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.
ATTENTION!
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and heat
source as small as possible. For this reason, it is advisable to de-
sign the heat source and heating system very carefully. A tem-
perature difference of approx. one Kelvin (1 °C) increases
the power consumption by around 2.5 %. When designing the
heating system, it should be borne in mind that special consum-
ers such as e.g. hot water preparation should also be considered
and dimensioned for low temperatures. Underfloor heating
systems (panel heating) are optimally suited for heat pump use
on account of the low flow temperatures (30 °C to 40 °C).
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.
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.
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.
The heat pump is equipped with an overflow mechanism to pre-
vent very low flow rates in the heat pump.
The installed buffer tank increases the amount of water in the
heating circuit and guarantees reliable defrosting.

2 Purpose of the Heat
Pump
3 Scope of Delivery
3.1 Basic Device
The compact heat pump is supplied complete with all of the im-
portant components of the heating circulation system:
2.1 Application
The air-to-water heat pump is designed for use in existing or
newly built heating systems.
„ Expansion vessel
„ Heat circulating pump
It is designed exclusively for heating and cooling heating water!
„ Overflow valve and safety components (pressure relief
In heating operation, the heat pump is suitable for mono energy
and bivalent operation down to an external temperature of -
20 °C.
valve, pressure gauge)
R404A is used as the refrigerant.
Proper defrosting of the evaporator is guaranteed by maintaining
a heating water return flow temperature of more than 18 °C dur-
ing continuous operation.
ꢀ
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).
ꢁ
ꢀꢁ
In cooling operation the heat pump is suitable for temperatures
ranging from +15 °C to +40 °C.
ꢀꢀ
ꢂ
It can be used for silent and dynamic cooling. The minimum
water temperature is +7 °C.
ꢀꢃ
ATTENTION!
The device is not suitable for operation with a frequency converter.

2.2 Operating Principle
ꢆ
Heating
ꢁ
ꢀ
Outside air is drawn in by the ventilator and fed via the evapora-
tor (heat exchanger). The evaporator cools the air, i.e. it extracts
heat from it. This extracted heat is then transferred to the working
medium (refrigerant) in the evaporator.
ꢇ
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).
1) Evaporator (heating operation)
2) Ventilator
3) 24 l expansion vessel
4) Switch box
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.
5) Liquifier (heating operation)
6) Compressor
The air-to-water heat pump consists of the main components
evaporator, ventilator and expansion valve, as well as the low-
noise compressor, liquifier and electrical control system.
7) Overflow valve
8) Heat circulating pump
9) Buffer tank
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.
10) Filter dryer
11) Inspection window
12) Expansion valve
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 compressor
raises the temperature level of the refrigerant and the heat is
passed on to the surrounding air via the liquifier (functioning as
an evaporator in heating operation).

3.2 Switch Box
The switch box is located in the heat pump. It can be accessed
by removing the lower front cover.
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.
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 control-
ler together with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.

6 Installation
5.1 General Information
6.1 General Information
The heat pump is designed for installation in a corner. Other in-
stallation locations are also possible in combination with an air
duct (available as an accessory) on the air outlet side.
The following connections need to be established on the heat
pump:
„ Fresh and exhaust air
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.
„ Flow and return flow of the heating system
„ Condensate outflow
„ Outflow for the pressure relief valve
„ Power supply
The heat pump must be installed so that maintenance work can
be carried out without being hindered. This can be ensured by
maintaining a clearance of 1 m in front and to the left of the heat
pump. The side panel assemblies must not be covered by
connecting pipes.
6.2 Air Connection
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
The air intake opening of the device is solely designed for direct
connection to a wall opening. The wall opening can be provided
with air duct and sealing collar for this purpose. See the illustra-
tion in the appendix under Installation Dimensions.
ꢄ P
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.
ꢄ 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 0 °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.
It must also be ensured that the interior side of the wall opening
is lined with thermal insulation to prevent the wall from becoming
cold and to prevent moisture from penetrating the wall. The en-
closed fixing accessories can be used for attachment to the wall.
5.3 Sound
To prevent solid-borne sound from being transmitted to the heat-
ing system, a vibration-damped connection should be used for
connecting the heat pump with the heating system (install the
supplied hose connections free of strain).
Installed air ducts should be sound-isolated from the heat pump
to prevent the transmission of solid-borne sound to the ducts.
If both air openings are connected directly to a wall opening, the
ventilator terminals can be reversed from a delta to a star con-
nection (see information in the ventilator terminal box).

6.4
An overflow valve is installed in the device for systems in which
the heating water flow can be shut off via the radiator or thermo-
stat valves. This ensures a minimum heating water flow rate
through the heat pump and helps to avoid faults.
ꢁꢆ[ꢆꢁꢇ
0ꢆꢈꢆ[ꢆꢁ
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested.
The integrated expansion vessel has a volume of 24 litres. This
volume is suitable for buildings with a living space area to be
heated of maximum 200 m².
The volume should be checked by the heating system engineer.
If necessary, an additional expansion vessel must be installed
(according to DIN 4751, Part 1). The tables listed in the manufac-
turers' catalogues simplify dimensioning the system on the basis
of the water content. Allow for a buffer tank volume of 80 litres
when making the calculation.
ATTENTION!
In the case of large-volume heating circuits, an additional expansion
vessel must be used to supplement the installed expansion vessel (24
litres, 1.0 bar admission pressure).
The air outlet can be optionally mounted directly to a wall open-
ing or to a longer duct (available as an accessory). Use the same
mounting procedure as for the air inlet.
Antifreeze
If a flange-mounted air duct is used on the air outlet side, it is se-
cured with 4 M8 x 16 hexagon bolts in the threaded holes pro-
vided. When doing this, ensure that the air duct stubs only touch
the insulation. There should be no contact with the external
sheeting.
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 pumps 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).
0 ꢁ [ ꢄꢀ
6.4 Electrical Connection
The power supply and control voltage are supplied using stand-
ard cables (load: 3-core, control: 3-core).
Observe the external and internal dimensions as specified in the
figure. Also ensure that the vibration and duct isolation are ade-
quate.
A disconnecting device with a contact gap of at least 3 mm (e.g.
utility blocking contactor or power contactor) as well as a 1-pole
circuit breaker must be installed in the power supply by the cus-
tomer (tripping current in compliance with the Device Informa-
tion).
6.3 Heating System Connection
To enable connection to the heating system, flexible hose con-
nection pieces and double nipples with a 1" external thread are
included with the heat pump. These allow the optional use of a
threaded or flat gasket connection to the heating system.
If the heat pump is not intended to be used to heat up the hot wa-
ter, the hot water output must be permanently sealed using the
supplied sealing plug.
The control voltage must be protected by a 10 A fuse. See Ap-
pendix Circuit Diagrams for detailed 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.

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.
„ All valves that could impair the proper flow of the heating
Any faults occurring during operation are also displayed on the

row.
„ The heat pump controller must be adapted to the heating
system in accordance with the controller's operating instruc-
tions.
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.
„ The outflow from the heating water pressure relief valve
3) Use the controller to select the automatic operating mode.
must also function correctly.
4) Wait until the buffer tank has reached a temperature of at
least 25 °C.
„ De-aeration of the heating system:
Ensure that all heating circuits are open and the heat circu-
lating pump is operating (level III).
Connect the voltage to the heat pump controller. Select the
heat generator 2 operating mode and de-aerate the system
at its highest point. Top up with water if required (maintain
static minimum pressure).
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.
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.
7.3 Start-Up Procedure
The heat pump is started up via the heat pump controller. Adjust-
ments should be made in compliance with the instructions.
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 2nd 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 performance level of the circulating pump must be adapted
to the respective heating system.
The overflow valve must be adjusted to the requirements of the
respective heating system. Incorrect adjustment can lead to
faulty operation and increased energy consumption. We recom-
mend carrying out the following procedure to correctly adjust the
overflow valve:
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).
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 the heat-
ing period. Do this by opening the left and front sides of the heat
pump. The bottom should be opened first followed by the top.
8.1 Maintenance
To protect the paintwork, avoid leaning 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
operating malfunctions due to contamination still occur, the sys-
tem 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 shown on the heat pump manager display.
Simply consult the Faults and Trouble-shooting page in the oper-
ating instructions of the heat pump manager. If you cannot cor-
rect 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!
Work on the heat pump may only be carried out 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!
The buffer tank is drained using the filling and drain cocks on the
lower left of the device. Also open the ball valve on the pressure
expansion vessel to vent the buffer tank.
