1.1 Important Information
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 the rotary field is clockwise when connecting the mains cables (if
the rotary field is not clockwise, the heat pump will not work properly, is
very loud and may cause damage to the compressor).
ATTENTION!
If the heat pump or circulating pumps are controlled externally, an
additional flow rate switch is required to prevent the compressor from
being switched on when there is no volume flow.
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 Intended Use
This device is only intended for use as specified by the manufac-
turer. Any other use beyond that intended by the manufacturer is
prohibited. This includes the user's abiding by the manufacturer's
product brochures. Please refrain from tampering with or altering
the device.
1.3 Legal Regulations and
Directives
This heat pump is designed for use in a domestic environment
according to Article 1, Paragraph 2 k) of EC directive 2006/42/EC
(machinery directive) and is thus subject to the requirements of
EC directive 2006/95/EC (low-voltage directive). It is thus also in-
tended for use by non-professionals for heating shops, offices
and other similar working environments, in agricultural establish-
ments and in hotels, guest houses and similar / other residential
buildings.
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.
1.4 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 manager is also important
for energy-efficient use of the heat pump. Further information can
be found in the heat pump controller's operating instructions.
