1.1 Important information
ATTENTION!
Any work on the heat pump may only be performed by an authorised and
qualified customer service.
ATTENTION!
When operating or maintaining a heat pump, the legal requirements of the
country where the heat pump is operated apply. Depending on the
refrigerant quantity, the heat pump must be inspected for leaks at regular
intervals by a certified technician, and these inspections must be
recorded.
ATTENTION!
The well water must comply with the required water quality standards.
ATTENTION!
If the heat pump or circulating pump is controlled externally, an
additional flow rate switch is required to prevent the compressor from
being switched on when there is no volume flow.
ATTENTION!
The heat pump must not be tilted more than max. 45° (in either direction).
ATTENTION!
The transport securing device is to be removed prior to commissioning.
ATTENTION!
The heating system must be flushed prior to connecting the heat pump.
ATTENTION!
It is essential that the dirt trap included in the accessories pack is
installed in the return (inlet).
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!
Commissioning is to be effected in accordance with the installation and
operating manual of the heat pump manager.
ATTENTION!
The supplied strainer must be fitted in the heat source inlet of the heat
pump in order to protect the evaporator against the ingress of impurities.
ATTENTION!
Disconnect all electrical circuits from the power supply before opening
the enclosure.

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 requires the user to abide by the manufacturers
product information. Please refrain from tampering with or alter-
ing 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.
This heat pump conforms to all relevant DIN/VDE regulations
and EU directives. For details refer to the EC Declaration of Con-
formity in the appendix.
The electrical connection of the heat pump must be performed
according to and conforming with all relevant VDE, EN and IEC
standards. Beyond that, the connection requirements of the local
utility companies have to be observed.
The heat pump is to be connected to the heat source and heat
distribution systems in accordance with all applicable provisions.
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.
ATTENTION!
Any work on the heat pump may only be performed by an authorised and
qualified customer service.
ATTENTION!
When operating or maintaining a heat pump, the legal requirements of the
country where the heat pump is operated apply. Depending on the
refrigerant quantity, the heat pump must be inspected for leaks at regular
intervals by a certified technician, and these inspections must be
recorded.
More information is available in the chapter Care / Cleaning.
1.4 Energy-efficient use of the heat
pump
By operating this heat pump you contribute to the protection of
our environment. A prerequisite for an efficient operation is the
proper design and sizing of the heating system and the heat
source system. In particular, it is important to keep water flow
temperatures as low as possible. All energy consumers con-
nected should therefore be suitable for low flow temperatures. A
1 K higher heating water temperature corresponds to an in-
crease in power consumption of approx. 2.5 %. Low-temperature
heating systems with flow temperatures between 30 °C and
50 °C are optimally suited for energy-efficient operation.
