1.1 Important Information
ATTENTION!
The device is not suitable for operation with a frequency converter.
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
ATTENTION!
The heat pump and transport pallet are only joined by the packing film.
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.
ATTENTION!
Ensure that there is a clockwise rotating field: Operating the compressor
in the wrong rotational direction could cause damage to the compressor.
ATTENTION!
Never use cleaning agents containing sand, soda, acid or chloride as
these can damage the surfaces.
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!
Before opening the device, ensure that all circuits are isolated from the
power supply.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
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).
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.
When connecting the heating and/or cooling system, all applica-
ble regulations must be adhered to.
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.
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.
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).
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.
2 Purpose of the Heat
Pump
2.1 Application
The air-to-water heat pump is designed for use in existing or
newly built heating systems.
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.
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.
It can be used for silent and dynamic cooling. Minimum water
temperature +7 °C.
ATTENTION!
The device is not suitable for operation with a frequency converter.
