1.3 Intended use
This device is only intended for use as specified by the manu-
facturer. Any other use beyond that intended by the manufac-
turer is prohibited. This requires the user to abide by the rele-
vant project planning documents.
1.4 Legal regulations and directives
This heat pump is designed for use in a domestic environment
according to Article 1, Paragraph 2 k) of EU directive 2006/42/
EC (Machinery Directive) and is thus subject to the require-
ments of EU directive 2014/35/EU (Low Voltage Directive). It is
thus also intended for use by non-professionals for heating
shops, offices and other similar working environments, agricul-
tural establishments and hotels, guest houses and other resi-
dential buildings.
The construction and design of the heat pump complies with all
relevant EU directives, and DIN/VDE regulations (see CE decla-
ration of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be adhered to. Any fur-
ther connection requirements stipulated by local utility compa-
nies must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
This unit can be used by children aged 8 and over and by per-
sons with limited physical, sensory or mental aptitude or lack of
experience and/or knowledge, providing they are supervised or
have been instructed in safe use of the unit and understand the
associated potential dangers.
Children must not play with the device. Cleaning and user
maintenance must not be carried out by children without su-
pervision.
NOTE
When operating or maintaining a heat pump, the legal
requirements of the country where the heat pump is operated
apply. Depending on the refrigerant fill quantity, the heat
pump must be inspected for leaks at regular intervals by a
certified technician, and these inspections must be recorded.

1.5 Energy-efficient use of the heat
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 sys-
tem.
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
design the heat source and heating system very carefully. A
temperature difference of approx. 1 Kelvin (1 °C) increases
the power consumption by around 2.5 %. When designing
the heating system, it should be borne in mind that special con-
sumers such as domestic hot water preparation should also be
taken into consideration and dimensioned for low tempera-
tures. Underfloor heating systems (panel heating) are opti-
mally suited for heat pump use on account of the low flow tem-
peratures (30 °C to 40 °C).
It is important to ensure that the heat exchangers are not con-
taminated during operation, as this increases the temperature
difference, which in turn reduces the coefficient of perfor-
mance (COP).
When set correctly, the heat pump manager is also an essential
factor in the energy-efficient use of the heat pump. Further in-
formation can be found in the heat pump manager operating
instructions.
