1.1. Idea of action for the heat pump
The principle of the heat pump is to collect heat from the so-called low-temperature lower source (-20°C to
+35°C) and transfer the heat to the high-temperature upper source (the central heating and DHW system). This
process is carried out with electricity supplied to drive the compressor.

Fig. 1. Principle of operation of a heat pump
In heat pump systems, it is possible to use both the hot side (upper source), e.g. for heating purposes, and the
cold side (lower source - air), e.g. for air conditioning or refrigeration. In the heat pump settings, we can select
the following modes of operation:
• Plant – central heating,
• DHW – domestic hot water,
• Plant + DHW – central heating + domestic hot water,

INSTRUCTION MANUAL – HEAT PUMP
2.3. Important warnings
The device is not intended for use by children. Read this manual before use.
Assembly, disassembly, installation work
and maintenance of the device must be
performed by qualified personnel.
It is forbidden to make any changes to the
structure of the unit. Failure to do so may result
in injury to persons or damage to the unit.
Before performing any operations on the
unit, make sure that the electrical power
to the heat pump unit is turned o.
If the power cord becomes loose or
damaged, make sure to always call
a qualified person to repair it.
The power supply to the device
must be grounded. The device should be kept away from environments that are flammable or corrosive.
A dedicated electrical connection should be used
to power the device, otherwise, failure may occur. Do not touch the grille of the air exhaust and outlet.
Do not direct a stream of water
directly on the device. Power leakage
or product failure may occur.
When the device is in operation, never cover it
with clothes, cloth or other material that blocks
the ventilation of the product, as this may lead to
low eciency or even malfunction of the device.
If the power cord is damaged, take the device out
of service and call a qualified person to repair it.
It is mandatory to use the appropriate heat
pump circuit breaker and make sure that the
power supply complies with the specifications.
Otherwise, the unit may be damaged.

INSTRUCTION MANUAL – HEAT PUMP
2.4. Risks as a result of product changes
• Never remove, bridge or block safety devices.
• Do not tamper with safety devices.
• Do not make any changes to the product, to the supply lines, to the heating circuit safety valve.
2.5. Risks of personal injury and property damage as a result of improper maintenance
and repair or failure to do so
• Perform maintenance annually before the heating season.
• Never perform repairs or maintenance work yourself.
• Have an authorized installer perform repairs and maintenance work.
• Adhere to designated maintenance intervals.
2.6. Risk related to improper use
Improper use can lead to damage to the heat pump, danger to those operating the unit and
others in the vicinity.
2.7. Risk of burn injury
The pipes from the water exchanger located in the heat pump should be carefully insulated,
since the maximum possible temperature of the pipes is 75 degrees Celsius.
2.8. Risk of malfunction due to incorrect electrical supply
Avoid interference with the operation of the product, the electrical supply should be within the speci-
fied limits:
• 3-phase: ~400 V (+10%), 50 Hz
2.9. Risk of environmental contamination from leaking refrigerant
The product contains refrigerant R290 called natural refrigerant gas. The GWP rating of this refrigerant
is 3.
Only an installer with the
proper licenses issued by the
manufacturer and protective
equipment may perform instal-
lation and maintenance work.
Installation of the unit must
be a minimum of 1m away
from windows, doors, lighting
ducts, roof windows, hatches,
drain pipes and ventila-
tion ducts due to possible
leakage of flammable gas.
R290
In case of repairs, do not use
sparking devices or other
devices that can cause an
ignition of the refrigerant.
R290
Condensate drainage must
not be introduced into the
sewer system, as it may create
an explosive atmosphere.
R290
Do not use open flames or
other devices that can heat up
the temperature to 370°C in
the heat pump environment.
In the event of a leak or suspected leak of
refrigerant, immediately turn o the unit.
Then remove any equipment from the envi-
ronment that may be a potential source of
fire and contact the service department.

INSTRUCTION MANUAL – HEAT PUMP
3. DOCUMENTATION
3.1. Description of Monoblock pump operation
A monobloc heat pump is a compact unit containing all the components of the refrigeration system and the heat
exchanger in which the heating medium for central heating and domestic water is heated.
The outdoor unit contains refrigeration components including the fan, evaporator and compressor, condenser,
valves and auxiliary fittings. The compressor (5) pumps hot gas which goes to the four-way valve which performs
the function of switching heating/cooling modes (defrost), then the gas goes to the condenser (6) in which it gives
up heat to the medium (water, glycol) which then goes to the facility for heating or hot water. The condensed,
subcooled medium in the form of liquid goes to the electronic expansion valve (EEV)(4), where expansion takes
place, then goes to the lower heat source (evaporator)(1) the medium takes heat from the environment this is
done by air flow through a fan forced exchanger (2).
The refrigerant in the evaporator evaporates and returns in the gas fraction to the compressor.
The indoor installation is equipped with a three-way valve (3-WAY), which distributes the heated medium for
central heating or hot water purposes (in priority). In the case of very low ambient temperatures and the required
higher temperature for heating purposes, an electric heater is additionally used to raise the temperature parame-
ter of the medium, which also has a protective function in the event of failure of the refrigeration system to ensure
a positive temperature and minimize the risk of freezing of the medium in the condenser.
3.1.1. Product conformity (CE marking)
CE marking or CE marking placed on a product is a manufacturer’s declaration that the marked product conforms
to the directives so-called New Approach of the European Union.
The declaration of conformity is available for inspection from the manufacturer.
