Description
Heat pump HPM is a device used to heat/cool the building and heat the domestic hot
water.
Device is equipped with two units:
- outdoor unit HPMO, compressor heat pump.
Operation of the device is based on taking heat from the environment and forwarding
it to the heating circuit in the building. Low temperature air heat is transferred through
the evaporator into the heat pump system lled a refrigerant, which evaporated turns
to gas. The gas from the evaporator is sucked in by compressor, which raises its
temperature and transfers it when it is compressed to the condenser. In the condenser,
heat is transferred to the medium lling the central heating system, cooled liquid
ows through the expansion valve and goes back to the evaporator, whereupon the
whole process starts again. In the case of cooling, this cycle is reversed and heat is
extracted from the building and discharged outdoor.
- indoor HPMI unit with a built-in heating system controller.
The principle of operation of the device is based on the need-based regulation of
the capacity of the heat pump compressor with the switching of the electric heater
via the internal module controller. The indoor module control unit regulates the
rated power according to the set heating curve. If the heat pump is unable to cover
the building's heat demand on its own, the controller will automatically start the
additional electric heater which, together with the heat pump, produces the required
temperature of the heating medium.

Conditions for use and reliable operation of the device
1. Reading the contents of this instruction manual will enable proper installation and
operation of the device, ensuring its long-term and reliable operation.
2. The heat pump must be installed in accordance with the guidelines contained in
this user manual.
3. The HPM.P heat pump heating system consists of a set of optimally selected ele-
ments:
- HPMI indoor unit
- HPMO outdoor unit
- DHW cylinder SWPC
- SVK buffer tank
which guarantee the ecient and reliable operation of the HPM heat pump.
4. The manufacturer guarantees the correct operation and effective parameters of
the HPM heat pump only in cooperation with devices of the HPM.P.
5. The manufacturer is not responsible for the installation of the HPM heat pump with
other devices which may result in incorrect operation, lack of effective operating
parameters and increased operating costs of the heating system or a breakdown
of the HPM heat pump.
6. The manufacturer is not responsible for an incorrectly selected device to the heating
needs of the installation.

Heating and DHW mode with the heat pump switched off
When the outdoor temperature drops below the set shut-down temperature value,
the heat pump is automatically turned off and cannot produce heating water. In this
case, the heating and DHW mode is automatically performed by the additional electric
heater of the indoor unit.
Automatic defrost
Defrosting of the evaporator surface is done by reversing the refrigerant's circulation.
During the defrosting process the compressed gas is discharged from the compressor
to the evaporator, which melts the existing frost. The heating system cools down
slightly during this time. Duration the defrosting process depends on the degree of
frosting and the current external temperature. Active defrosting process is signaled
on the control panel by the icon .
Transport and storage
The HPMO heat pump should be transported and stored in a horizontal position.
Assembly
The heat pump is designed for outdoor installation and connection to indoor hydraulic
module with integrated additional electric heater. The device must be placed on a solid,
level base or foundation concrete. For fastening, use the attached vibration isolators.
To protect the device against snow and excessive moisture, base or the foundation
should protrude around 300mm above the ground level.
Prepare the ground under the foundation for free drainage of the condensate from
the drip tray. Drainage should be below the freezing zone. The layer thickness and
level must comply with local requirements and principles of construction technique.
The hole diameter should not be less than 100mm.
Condensate drain pipe should be thermally insulated. Thorough leveling the HPMO
outdoor unit will allow for free drainage of the condensate from the drip tray.
The heat pump should not be placed against the wall of rooms where noise could
interfere; e.g. by the bedroom wall. In order to maintain the high eciency of device it
is necessary to keep minimum distance against building's walls and other obstacles.
Restriction of the air ow can lead to the intake of cooled (heated in cooling mode)
air and lead to an increase in energy consumption of the compressor.
Connect the heating medium pipes to the heat pump and hydraulic module.
