1.1 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.
1.2 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 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 and VDE regulations.
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 country-specific reg-
ulations 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.

ATTENTION!
Work on the heat pump must only be performed by author-
ised and qualified after-sales service technicians!

NOTE
When operating or maintaining a heat pump, the legal require-
ments 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.
1.3 Energy-efficient use of the heat
pump
By operating this heat pump you are helping to protect our en-
vironment. The heating system must be properly designed and
dimensioned to ensure efficient operation. It is particularly im-
portant to keep water flow temperatures as low as possible in
heating operation. All connected heat consumers should there-
fore be suitable for low flow temperatures. Raising the heating
water temperature by 1 K corresponds to an increase in electric
energy consumption of approx. 2.5 %. Low-temperature heat-
ing systems with flow temperatures between 30 °C and 50 °C
are particularly well-suited for energy-efficient operation.
