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
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, in agri-
cultural establishments and in hotels, guest houses and similar
/ other residential buildings.
This heat pump conforms to all relevant DIN/VDE regulations
and EU directives. Refer to the EC Declaration of Conformity in
the appendix for details.
The heat pump must be connected to the power supply in
compliance with all relevant VDE, EN and IEC standards. Any
further connection requirements stipulated by local utility com-
panies must also be observed.
The heat pump is to be connected to the heat source system
and the heating system in accordance with all applicable regu-
lations.
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!
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 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 our en-
vironment. Both the heating system and the heat source must
be properly designed and dimensioned to ensure efficient op-
eration. It is particularly important to keep water flow tempera-
tures as low as possible. All connected energy consumers
should therefore be suitable for low flow temperatures. Raising
the heating water temperature by 1 K corresponds to an in-
crease in energy consumption of approx.
2.5 %. Low-temperature heating systems with flow tempera-
tures between 30 °C and 50 °C are particularly well-suited for
energy-efficient operation.

Purpose of the Heat Pump

2.1 Application

The brine-to-water heat pump is to be used exclusively for the
heating of heating water. It can be used in new or previously ex-
isting heating systems. A mixture of water and antifreeze (brine)
is used as the heat transfer medium in the heat source system.
Borehole heat exchangers, ground heat collectors or similar
systems can be used as the heat source system.

2.2 Operating Principle

The heat generated by the sun, wind and rain is stored in the
ground. This heat stored in the ground is collected at a low tem-
perature by the brine circulating in the ground collector, ground
coil or similar device. A circulating pump then conveys the
"heated" brine to the evaporator of the heat pump. There the
heat is given off to the refrigerant in the refrigerating cycle. This
cools the brine so that it can once again absorb thermal energy
in the brine circuit.
The refrigerant is drawn in by the electrically driven compres-
sor, compressed and "pumped" to a higher temperature level.
The electrical power needed to run the compressor is not lost in
this process. Most of it is absorbed by the refrigerant.
Subsequently, the refrigerant is passed through the condenser
where it transfers its heat energy to the heating water. Depend-
ing on the set operating point (thermostat setting), the heating
water is thus heated up to a max. of 62 °C.
