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).
1 Please Read
Immediately
1.1 Important Information
The relevant VDE, EN and IEC standards must be adhered to
when connecting the heat pump to the power supply or carrying
out maintenance work. Any further connection requirements stip-
ulated by local utility companies must also be observed.
ATTENTION!
When connecting the heating system, all applicable regulations
must also be adhered to.
ATTENTION!
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
ATTENTION!
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.
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
Children must be supervised to ensure that they do not play with
the device.
ATTENTION!
1.3 Energy-Efficient Use of the
Heat Pump
ATTENTION!
ATTENTION!
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 system
(radiators and circulation pump).
ATTENTION!
To maintain heat pump efficiency, it is particularly important to
keep the temperature difference between the heating water and
heat source to a minimum. 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 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. DHW preparation should also be taken into con-
sideration 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!
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 operating instructions of the heat pump controller.

3.1
2 Purpose of the Heat
Pump
3 Scope of Delivery
3.1 Basic Device
The heat pump is of compact design and is supplied complete
with the components listed below.
2.1 Application
The air-to-water heat pump is designed for use in existing or
newly built heating systems.
R290 (propane) is used as refrigerant.
It is designed exclusively for heating domestic hot water and
heating water!
The heat pump is suitable for mono energy and bivalent opera-
tion down to an external temperature of -20 °C.
Proper defrosting of the evaporator is guaranteed by maintaining
a heating water return flow temperature of more than 13 °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).
ATTENTION!
The device is not suitable for operation with a frequency converter.
2.2 Operating Principle
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.
The heat is “pumped” to a higher temperature level by increasing
its pressure with the aid of electrically driven compressors. It is
then transferred to the heating water via the liquifier (heat ex-
changer).
1) Evaporator
2) Ventilator
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.
3) Switch box
4) Filter dryer
5) Expansion valve
6) Liquifier
The air-to-water heat pump consists of the main components
evaporator, ventilator and expansion valve, as well as the low-
noise compressors, the liquifier and the electrical control system.
7) Compressor
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.

3.2
3.2 Switch Box
The switch box is located in the heat pump. All electrical compo-
nents are accessible after the front cover and the switch box
cover have been removed.
4 Transport
ATTENTION!
Never install the device in rooms in which there are any permanent
ignition sources.
The switch box contains the supply connection terminals, the
plug connector for the control line, as well as the power contac-
tors and the soft starter unit.
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
3.3 Heat Pump Controller
Use the heat pump controller included in the scope of supply to
operate the air-to-water heat pump.
The heat pump should be transported to its final installation loca-
tion packaged and using the wooden pallet. The device can be
transported to its final location e.g. with a lift truck or one or two
hand trucks.
The heat pump controller is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system on the basis of the external temperature, including do-
mestic hot water preparation and safety systems.
The customer must install the return temperature sensor and the
external temperature sensor, which are supplied with the heat
pump controller / with these instructions together with the neces-
sary fixing accessories.
The operating instructions included in the scope of supply of the
heat pump controller describe its function and use.
The devices LA 12PS and LA 18PS are packaged with transport
pipes on the wooden pallets. These pipes can be inserted using
the boreholes of the heat pump base frame (they are sealed with
cover caps, which can easily be removed), and can be used for
manual transport by securing them on both sides using the
spring cotters to keep them from slipping out of place.
1) Frame
2) Transport pipe
3) Spring cotters
ATTENTION!
The heat pump and transport pallet are only joined by the packing film.

5 Set-up
6 Installation
5.1 General Information
6.1 General Information
The heat pump is suited for outdoor installation. The device
should always be installed on a permanently smooth, even and
horizontal surface and must be aligned vertically. The entire
frame should lie directly on the ground to ensure a good sound-
proof seal and to prevent the water-bearing components from be-
coming too cold. If this is not the case, additional insulation
measures may be necessary. It must be possible to carry out
maintenance work without hindrance. This can be ensured by
maintaining a clearance of 1.2 m to any fixed walls.
The following connections need to be established on the heat
pump:
„ Flow and return flow of the heating system
„ Condensate outflow
„ Control line to the heat pump controller
„ Power supply
6.2 Heating System Connection
The heating system connections on the heat pump have a 1" ex-
ternal thread.
Route the connection hoses out of the device in a downwards di-
rection. Use a spanner to firmly grip the transitions when con-
necting the heat pump. After the heat pump has been installed,
the ductwork must be sealed so that the connection is gastight.
ꢀꢁꢂ P
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc., and to prevent any accumulation of
deposits in the liquifier. A contaminated liquifier may cause the
heat pump to completely break down. Systems in which the heat-
ing water flow can be shut off via the radiator or thermostat
valves must be fitted with an overflow valve downstream from the
heat pump in a heating bypass (to be installed by the customer).
This ensures a minimum heating water flow rate through the heat
pump and helps to avoid faults.
ꢀꢁꢂ P
ꢀꢁꢂ P
ꢀꢁꢂ P
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested (in the heat pump the air-relief cock
is located at or in the water pipes at the condenser).
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
$LUꢃUHOLHIꢄFRFN
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.
&RQGHQVDWRU
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.
E-5

6.3
The control line (not included in scope of supply) is connected to
the heat pump controller using the two rectangular plug connec-
tors and the single-core wire. The plug connector is located on
the bottom side of the switch box inside the heat pump. More de-
tailed information can be found in the operating instructions of
the heat pump controller.
Antifreeze
Manual drainage should be provided for heat pumps which are
exposed to frost. The antifreeze function of the heat pump con-
troller is active whenever the controller 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, and if required, blown out, at three locations (see illus-
tration). 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 detected (holiday home).
For detailed information, see Circuit Diagrams in the Appendix.
7 Start-up
7.1 General Information
To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorised by the
manufacturer. This may be a condition for extending the guaran-
tee (see Warranty).
ꢅ
7.2 Preparation
ꢀ
The following items need to be checked prior to start-up:
„ The heat pump must be fully connected, as described in
Chapter 6.
„ All valves that could impair the proper flow of the heating
ꢂ
water in the heating circuit must be open.
„ The air intake and air outlet paths must be clear.
6.3 Electrical Connection
„ The ventilator must turn in the direction indicated by the ar-
row.
A standard four-core cable is used for connecting the heat pump
to the power supply.
„ The settings of the heat pump controller must be adapted to
the heating system in accordance with the controller’s oper-
ating instructions.
The power supply and the control line are normally installed in
the ground (in ductwork with a suitable size and resistance) and
routed from the heat pump to the building. This ductwork must
extend into the heat pump by approx. 22 mm and be installed
with a continuous downward slope in order to comply with Sec-
tion 42 of the VDE 0100 regulations. Instead of 90° bends, two
45° bends must be used as pipe bends. The control line and the
cable for the power supply are drawn into this ductwork.
„ Ensure the condensate outflow functions properly.
7.3 Procedure
The heat pump is started up via the heat pump controller. Adjust-
ments should be made in compliance with the instructions.
The cable (power supply) must be provided by the customer. The
conductor cross section is selected in accordance with the power
consumption of the heat pump (see Appendix Device Informa-
tion) and the applicable VDE (EN) and VNB regulations.
If an overflow valve is fitted to assure the minimum heating water
flow rate, the valve must be set in accordance with the require-
ments of the respective heating system. Incorrect adjustment
can lead to faulty operation and increased energy consumption.
We recommend carrying out the following procedure to correctly
adjust the overflow valve:
The power supply line on the heat pump must be fed through the
provided cable feedthrough into the switch box. The line must be
firmly screwed to its feedthrough (vapour sealed pipe union).
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).
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). Ensure that the in-
coming supply has a clockwise rotating field when connecting
multiphase devices.
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.
Phase sequence: 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 is supplied via the heat pump controller.
The heat pump controller has a 230 V AC-50 Hz power supply.
Connect the controller in compliance with its own operating in-
structions (16 A fuse).

To prevent faults due to sediment in the heat exchanger of the
heat pump, ensure that the heat exchanger in the heating system
cannot be contaminated. In the event that operating malfunctions
due to contamination still occur, the system should be cleaned as
described below. The device may only be cleaned according to
the following instructions from the manufacturer.
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.
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.
8.2 Cleaning the Heating System
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.
Observe the following procedure to implement a smooth start-up:
1) Close all of the heating circuits.
2) Fully open the overflow valve.
3) Use the controller to select the automatic operating mode.
4) Wait until the buffer tank has reached a temperature of at
least 25 °C.
ATTENTION!
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.
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.
Residue from lubricants and sealants may also contaminate the
heating water.
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.
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.
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.
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.
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!

8.3
8.3 Cleaning the Air System
Evaporator, ventilator and condensate outflow should be cleaned
of contamination (leaves, twigs, etc.) before each new heating
period.
9 Faults / Trouble-
Shooting
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.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
To prevent the evaporator and the condensate tray from being
damaged, do not use hard or sharp objects for cleaning.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
ATTENTION!
The refrigerating circuit may not be damaged in any way.
Inflammable refrigerant could leak out if the refrigerating circuit is
damaged. Ignition sources and open flames must be avoided
when carrying out any work on the device.
Anyone carrying out work on the refrigerating circuit must be cer-
tified to safely handle inflammable refrigerants or be supervised
by a person having such certification.
Under extreme weather conditions (e.g. snow drifts), ice may
form on the air intake and exhaust air outlet grids. If this happens,
the ice must be removed in the vicinity of the air intake and ex-
haust air outlet grids to ensure that the minimum air flow rate is
maintained.
10 Decommissioning /
Disposal
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.
