1Safety 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

ºººº

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.

2 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.
