1.3 Legal Provisions and Guidelines

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, 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. For details refer to the EC Declaration of
Conformity 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 accord-ance with all applicable provi-
sions.
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!
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 can be found in the accompanying log book.
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-tempera-
ture heating systems with flow temperatures between 30 °C
and 50 °C are optimally 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. The mixture of water and frost protec-
tion (brine) acts as a heat transfer medium in the heat source
system. Ground probes, ground heat collectors or similar sys-
tems can be used as heat source systems.

2.2 Principle of Operation

The heat generated by the sun, wind and rain is stored in the
ground. This heat stored in the ground is collected at low tem-
perature by the brine circulating in the ground collector, ground
coil or similar device.
A circulating pump then conveys the warmed brine to the evap-
orator of the heat pump. There, the heat is given off to the re-
frigerant in the refrigeration cycle. When so doing, the brine
cools so that it can again take up heat energy in the brine cir-
cuit.
The refrigerant is drawn in by the electrically driven compres-
sor, is compressed and "pumped" to a higher temperature
level. The electrical power needed to run the compressor is not
lost in this process, but most of the generated heat is trans-
ferred to the refrigerant.
Subsequently, the refrigerant is passed through the condenser
where it transfers its heat energy to the heating water. Based on
the thermostat setting, the heating water is thus heated to up to
70 °C.
