Injuries and environmental damage due to
refrigerant
The unit contains harmful and environmentally
dangerous refrigerant. If refrigerant leaks from the
unit:
1. Switch off unit.
2. Thoroughly ventilate installation room.
3. Notify authorised customer service.
2.5 Disposal
Batteries
Improper disposal of the buffer battery damages the
environment.
►Dispose of the buffer battery in an environmen-
tally compatible way according to the local regu-
lations.
Media harmful to the environment
Improper disposal of environmentally harmful media
(antifreeze, refrigerant) damages the environment:
►Collect media safely.
►Dispose of the media in an environmentally com-
patible way according to the local regulations.
2.6 Avoid damage to property
Improper action
Requirements for minimum scale and corrosion
damage in hot water heating systems:
●
Proper planning, design and start-up
●
Closed system with regard to corrosion
●
Integration of adequately dimensioned pressure
retention
●
Use of deionised heating water (VE water)
●
Regular servicing and maintenance
If a system is not planned, designed, started up and
operated according to the given requirements, there
is a risk that the following damage and faults will
occur:
●
Malfunctions and the failure of components, e.g.
pumps, valves
●
Internal and external leaks, e.g. from heat
exchangers
●
Cross-section reduction and blockages in
components, e.g. heat exchanger, pipes, pumps
●
Material fatigue
●
Gas bubbles and gas cushion formation
(cavitation)
●
Negative effect on heat transfer, e.g. formation
of coatings, deposits, and associated noises,
e.g.boilingnoises,ownoises
►Note and follow the information in this operating
manualforallworkonandwiththeunit.
Unsuitablequalityofthellandmake-up
water in the heating circuit
Theefciencyofthesystemandthelifeoftheheat
generator and the heating components depend
decisively on the quality of the heating water.
Ifthesystemislledwithuntreateddomesticwater,
calcium precipitates as scale. Limescale deposits
form on the heat transfer surfaces of the heating. The
efciency drops and energy costs rise. In extreme
cases the heat exchangers are damaged.
►Fill system with deionised heating water
(VE water) only.
Unsuitable quality of the water-antifreeze
mixture in the heat source
►For operation of the heat source with water-
antifreeze mixture, ensure that the water fulls
the quality specications of the heating water
side.

3.3 Function
Liquid refrigerant is evaporated (evaporator), the
energy for this process is environmental heat and
comes from the “ground” heat source (collector,
borehole heat exchanger or groundwater via
intermediate exchanger). The gaseous refrigerant
is compressed (compressor), this causes the
pressure to rise and therefore the temperature too.
The gaseous refrigerant with high temperature is
liqueed(condenser).
Here the high temperature is discharged to the
heating water and is used in the heating circuit.
The liquid refrigerant with high pressure and high
temperature is expanded (expansion valve). The
pressure and temperature drop and the process
begins again.
Due to the integrated changeover valve and the
integrated energy efciency circulation pump the
heated heating water can be used for charging the
domestic hot water or for heating the building. The
temperatures required and use are controlled by the
heat pump controller. Reheating, drying out screed
or increasing the domestic hot water temperature
can be carried out using the integrated electric
heating element, which is activated by the heat pump
controller as and when necessary.
An integrated overow valve ensures that the heat
pump does not switch to high-pressure fault if all
heating circuits are closed. The integrated vibration
isolators for the heating circuit and heat source
prevent structure-borne sound and vibrations from
beingtransferredontothexedpipesandtherefore
into the building.

Cooling
Cooling is integrated in type K units. Type H units
can be retrotted with the “Cooling package”
accessories. The following options are possible for
units with cooling function (operating manual of
the heating and heat pump controller):
●
Passive cooling (without compressor)
●
Control of the cooling function via the heating
and heat pump controller
●
Switching between heating and cooling
mode; automatically with expansion board
(accessories)
Networkconnectiononthecontrol
The control can be connected to a computer or
network viaa network cable. Theheatingand heat
pump controller can then be controlled from the
computerorfromthenetwork.
4 Operation and care
NOTE
The unit is operated via the control of
the heating and heat pump controller
(operating manual of the heating and heat
pump controller).
4.1 Energy and environmentally
aware operation
The generally accepted requirements for energy-
aware and environmentally-aware operation of a
heating system also apply to use of a brine/water
heat pump. The most important measures include:
●
Nounnecessarilyhighowtemperature
●
No unnecessarily high domestic hot water
temperature (note and follow local regulations)
●
Do not open windows with gap /tilt open
(continuous ventilation), but instead open wide
for a short time (purge ventilation).
4.2 Maintenance
Wipe down the outside of the unit only using a damp
cloth or cloth with mild cleaning product (washing-
up liquid, neutral cleaning product). Do not use any
harsh, abrasive, acid or chlorine-based cleaning
products.
5 Delivery, storage, transport
and installation
ATTENTION
Damage to the housing and the unit components
due to heavy objects.
►Do not place any objects on the unit which are
heavier than 30 kg.
5.1 Scope of supply

5.2 Storage
►Where possible do not unpack the unit until
directly before installation.
►Store unit protected against:
–Moisture/damp
–Frost
–Dust and dirt
5.3 Unpackingandtransport
Notes on safe transport
The housing with the unit components and the
module box are heavy (“Technical data/Scope of
supply” on page 24). There is a risk of injuries
or damage to property if the housing with the unit
components falls or overturns or if the module box
falls.
►The housing with the unit components and
module box must be transported and installed
by several persons.
►Secure the housing with the unit components
during transport. Carry the module box by the
carrying lugs.
Thereisariskofcuttingyourhandsonsharpedges
of the unit.
►Wear cut resistant protective gloves.
The hydraulic connections are not designed for
mechanical loads.
►Do not lift or transport the unit by the hydraulic
connections.
If the module box is tilted by more than 45°,
compressor oil runs into the cooling circuit.
►Do not tilt the unit with installed module box by
more than 45°.
Transport the unit preferably with a pallet truck,
alternatively with a handcart.
Transportwithapallettruck
►Transport the unit to the place of installation
packagedandsecuredonawoodenpallet.
