lIf the installation is not used during the winter, the heating system must be drained of
water, otherwise there is a risk of frost damage to the installation. (Contact an authorized
installer, see the ”References” section.)
lThe installation can be considered maintenance free but certain checks are necessary
(see “Regular checks” section).
lBefore changing the control computer’s settings, first find out what these changes mean.
lContact your installer for any service work.
!This apparatus is not intended for persons (including children) with reduced physical,
sensory or psychological capacity, or who do not have knowledge or experience,
unless supervised or they have received instructions on how the apparatus functions
from a safety qualified person.
!Children are not permitted to play with the apparatus.
1.1 Safety precautions
1.1.1 Installation and maintenance
lOnly authorized installers may install, operate and carry out maintenance and repair
work on the heat pump. (See the ”References” section)
lOnly authorized electricians may modify the electrical installation. (See the ”References”
section)
!
DANGER TO LIFE! Only authorized refrigeration technicians may work on the
refrigerant circuit. (See the ”References” section).
1.1.2 System modifications
Only authorized installers may carry out modifications on the following components:
lThe heat pump unit
lThe pipes for the refrigerant, brine, water and power
lThe safety valve
You must not carry out construction installations that may affect the operational safety of the
heat pump.
1.1.3 Safety valve
The following safety precautions apply to the hot water circuit’s safety valve with correspon-
ding overflow pipe:
lNever block the connection to the safety valve’s overflow pipe.
lWater expands when it is heated, this means that a small amount of water is released
from the system via the overflow pipe. The water that exits the overflow pipe can be hot!
Therefore, allow it to flow to a floor drain where there is no risk of burning yourself.
1.2 Protection
1.2.1 Corrosion Protection
Due to the risk of corrosion, avoid using different types of sprays in the vicinity of the heat
pump. This particularly applies to:
lSolvents
lChlorinated cleaning agents
lPaints
lAdhesives

2.1 Principles of function
A heat pump utilises the free energy found in a natural heat source, such as rock, ground, or
ground water. The heat pump can be compared to a reversed refrigerator. In a refrigerator, heat
is transferred from the inside of the refrigerator to the outside. In a heat pump the heat that is
stored in a heat source is transferred to the inside of the house. The heat pump uses the energy in
the heat source and gives back two to three times more heat energy than what it uses in electrical
energy. The heat pump is, therefore, a very environmentally friendly and economical way of
heating a house.
In order for the heat pump to be able to retrieve heating energy from the heat source and transfer
it to the heating system of the house, three separate fluid circuits are required.
The circuit that retrieves the heating energy from the heat source is called the brine circuit
and it maintains a low outgoing temperature to be heated by the heat source.
The next circuit is called the refrigerant circuit and is a closed circuit which takes the retrieves
heating energy and transfers it to the last circuit, the heat transfer fluid circuit.
The heat transfer fluid circuit holds the fluid that circulates in the heating system of the house
and in the heat pump’s water heater.
The figure below shows how the different circuits work together in the transfer of heating
energy.
Figure 1: Function principles of a heat pump.
Q A fluid (brine) filled hose is lowered into a lake, buried in the ground or lowered into bedrock. The brine
obtains energy from the heat source by the fluid temperature in the hose being heated a few degrees by
the surrounding heat source. The fluid filled hose is also known as a collector.

Heat transfer fluid circuit - is the circuit that contains
the water that transports the heat/energy to the heating
system and the water heater.
Refrigerant circuit - is the circuit that contains a chlorine
and freon free refrigerant which, inside the heat pump,
transfers the energy retrieved from the brine circuit
through evaporation, compression and condensation,
and supplies it to the heat transfer fluid circuit.
Brine circuit - is the circuit that contains an antifreeze
water based mix that obtains and transports energy from
the heat source to the heat pump. This circuit is also
known as the collector.

W The brine is guided into the heat pump’s evaporator. The enclosed refrigerant in the refrigerant cir-
cuit is forced to boil as the pressure in the expansion valve drops and later evaporates to a gas in
the evaporator. The energy produced during this process is released by the slightly heated brine.
E The refrigerant that now contains a large quantity of energy in the form of heat is transferred to the
compressor, which both increases its temperature and pressure.
R The refrigerant then continues to the condenser. When condensing, the refrigerant supplies its heat
energy to the heat transfer fluid circuit. The refrigerant’s temperature decreases and returns to a
liquid state.
TThe heat transfer fluid circuit transports the heat energy out to the water heater, radiator or the
under floor heating system, which heat up.
YThe refrigerant is then transported through the expansion valve where the pressure drops and the
refrigerant starts to boil and then the process starts again.
2.2 Components
The heat pump you acquired is a complete heat pump installation for heating and hot water.
It has the market’s first compressor developed solely for heat pumps. It has an integrated 180
litre water heater and auxiliary heating. The water heater uses Tap Water Stratificator, which
is technology that results in more effective heat transfer and
effective layering of the water in the water heater.
The heat pump unit is equipped with control equipment,
which is controlled via a control panel.
Heat enters the house via a water borne heating system, a
low temperature system. The heat pump supplies as much
of the heat demand as possible before auxiliary heating is
engaged and assists.
The heat pump unit consists of five basic parts:
QHeat pump
l Scroll compressor
l Stainless steel heat exchanger
l Circulation pumps for brine and heating systems
l Valves and safety equipment for cooling systems and
corresponding electrical components.
WWater heater
l 180 litres
l Internal anti-corrosion protection with copper or stain-
less steel
l It has an anode that does not require replacing,
which means that it is maintenance-free
EExchange valve
l The heated water either passes through to the hea-
ting system or to the water heater depending on whe-
ther heating or hot water is to be produced.
