Safety notes
1.1 Symbols and markings
Particularly important information in these instructions is
marked with CAUTION! and NOTE.
CAUTION!
Immediate danger to life or danger of severe personal injury or
significant damage to property.
NOTE
Risk of damage to property or minor personal injury or
important information with no further risk of personal injury
or damage to property.
1.2 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. Please refrain from
tampering with or altering the device.
1.3 Legal regulations and guidelines
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, guesthouses and other resi-
dential 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 adhered to. Any fur-
ther connection requirements stipulated by the mains supply
network operator 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 the 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.
CAUTION!
Work on the heat pump must only be performed by
authorised and qualified after-sales service technicians!
CAUTION!
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.
More information can be found in the accompanying log book.

1.4 Energy-efficient use of the heat
pump
By operating this heat pump, you are helping to protect the en-
vironment. A prerequisite for energy-efficient operation is the
correct design of the heat source system and heating system.
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 design the heat source and heating system very carefully. A
temperature difference of approximately one Kelvin (1 °C) in-
creases the power consumption by around 2.5 %. When de-
signing the heating system, it should be borne in mind that spe-
cial consumers such as domestic hot water preparation should
also be taken into consideration and dimensioned for low tem-
peratures. 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 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.
