WARNING!
The unit contains coolant!
If the coolant leaks, it poses risk to people and the environment, therefore, you must:
– turn off the system;
– make sure the installation room is well ventilated;
– inform the manufacturer’s customer service.
ATTENTION
For safety reasons, never disconnect the device from the power supply unless the device is open.
Do not use pure water in the outdoor circuit.
PRODUCT PACKAGING AND TRANSPORTATION
After purchasing a heat pump:
Inspect the delivered product for external damage during delivery;
In the event of delivery defects, submit a claim to the company that sold the device immediately.
The heat pump may only be transported and stored in an upright position. The device
can only be temporarily tilted, not laid down. The device can be stored at a temperature no lower
than 10 oC.

6
SELECTION OF THE INSTALLATION PLACE
When choosing the installation place of the heat pump, keep in mind that the heat pump
produces a certain level of noise (see table “Heat pump technical data”).
The device must be mounted on a flat and stationary surface with a permissible load of at least
500 kstr. Minor surface irregularities can be compensated by adjusting the feet of the device.
The ambient temperature near the heat pump must be between 10°C and 35°C, and the relative
humidity must not exceed 80%.
There must be no aggressive chemicals in the environment.
The heat pump should not be installed close to walls; the front of the unit should always be
accessible (see, Annex No 6).
A drainage system must be provided in the room where the unit is installed. In this case, leaking
water can be drained.
Do not use extra platforms.
PRELIMINARY PREPARATION OF THE PIPELINES
The connecting pipes for the outdoor circuit, the heating circuit and, if provided, the hot water
circuit must be laid up to the intended location of the heat pump. Install an expansion vessel, safety
valves, coarse suction filters and pressure gauges for the outdoor, heating circuit and boiler. The
circuits must have a provided filling point.
OUTDOOR CIRCUIT
Installation and filling
The outdoor circuit can be vertical (boreholes) or horizontal. The horizontal circuit must be
installed below the freezing zone, depending on the ground of the installation site. Fill the outdoor
circuit with glycol, which ensures that it does not freeze in temperatures up to -15oC. Do not use the
salt-based solution. The following fluids are approved for the outdoor circuit:
• monoethylene glycol;
• propylene glycol.
It is recommended to use a mixture of water and monoethylene glycol concentrate in a ratio of
3:1. The applicable rules and regulations must be observed when installing and filling the outdoor
circuit. There must be no stones or sharp objects in the ground where the outdoor circuit is installed
that could damage the pipes. Prior to filling the system, make sure that the system is tightly sealed.
When installing the outdoor circuit, it is necessary to protect the pipes from penetration of dirt
or gravel. If the system is dirty, the heat pump may become clogged and individual components of
the device may be damaged or corrupted.
Filling and circulating unit
The outdoor system refiller must be installed next to the circuit inlet so that the system can be
replenished when the system pressure drops and the external and glycol mixing procedure can be
performed when filling the outdoor circuit. The filling unit is not included in the heat pump
package.

7
Automatic air release valves
In order to ensure that no air clogs occur in the outdoor circuit system and that the heat pump
does not signal an alarm as a result, it is necessary to install automatic air release valves on the
outdoor circuit. The air release valves must be installed at the highest points of the circuit.
Outdoor circuit pump
The outdoor circuit pump is included in the heat pump set and is installed in the device at the
factory. The Grundfos UPM3 pump (see, Annex No 2) is the most commonly used for the outdoor
circuit, and the UPMXL heat pumps with a capacity of more than 11 kW (see, Annex No 2). The
circulation pump is controlled by the central processor while maintaining optimal flow. The control
system monitors the operation of the circulation pumps and a warning is received in the event of a
deviation.
INTERNAL CIRCUIT
To avoid gas formation, it is recommended not to use galvanised pipe systems.
WARNING!
The area of the domestic hot water tank heat exchanger must correspond to the capacity of
the heat pump. The water capacity must be such that the heat output of the heat pump is
transmitted as efficiently as possible.
NOTE
Integrate the hot water tank into the heat pump system to match the heating system scheme
you have selected (see, pages 14-17).
Heating system filling
Set the pressure of the heating circuit in the expansion vessel to 1.5 bar. Usually the
replenishment of the heating circuit is stationary, pre-connected to the water inlet, in which case the
replenishment takes place individually according to the system. If the filler in the heating circuit is not
water, then the system is filled with the appropriate liquid. As an additional protection against
freezing, in some cases the water in the heating system may be mixed with glycol, however, this
concentration should not exceed 15%. In this case, the efficiency of the heat pump decreases.

8
Flow through the heating system
A bypass is required in the mixing circuit, if an adjustable circulation pump is used, which is
controlled by differential pressure. Bypass is not included with the heat pump. If a buffer tank
bypass is installed in parallel with the heating system, no bypass is required.
Heating system filter and valves
The heat pump does not include a filter and a safety valve. These components must be
installed on the pre-prepared heating system return line. The safety valve shall be installed vertically.
WARNING!
Do not leave the safety valve closed.
Internal circuit circulation pump
The internal circuit pump is included in the heat pump set and is installed in the device at the
factory. The Grundfos UPM3 pump (see, Annex No 2) is the most commonly used for the internal
circuit, and the UPMXL heat pumps with a capacity of more than 9 kW (see, Annex No 2). The
circulation pump is controlled by the central processor while maintaining optimal flow. The control
system monitors the operation of the circulation pumps and a warning is received in the event of a
deviation.
Heating system rinsing and filling
The heat pump is an integral part of the heating system. Heat pump failures are usually caused
by poor water quality in the heating system, or by presence of air in the system. The presence of air
in the system produces corrosive products such as magnetite or sediment. Magnetite has an
abrasive effect that is especially enhanced in pumps, valves, or eddy-flow components, such as a
condenser. Prior to installing a heat pump in a heating system that needs to be filled or uses water
that is not pure, auxiliary measures such as the installation of filters and automatic outlets must be
taken. Filling with untreated drinking water will inevitably result in formation of a sediment. Effect:
formation of limescale deposits on the heat transfer surfaces. Decreased efficiency and energy
consumption increases. 1 millimetre of lime deposits causes an energy loss of 10%. In extreme
cases, this can even damage the heat exchangers.
Do not use water treatment additives in the heating system. Additives can be used to adjust the
pH of the water, the recommended pH of the water is 7.5-9. The safest and most efficient operation
of the system is achieved by using low-salt water.
When combining a heat pump with a boiler, it may be necessary to fill the system with
desalinated water to protect the boiler from corrosion. This reduces electrical conductivity and risk of
corrosion.
WARNING!
Sediment in the piping can damage the heat pump. To prevent this, make sure to flush the
pipes.
Damage to sediment and corrosion heating systems is low if:
- planning and start-up are carried out properly;
- the system is closed in terms of corrosion;
- pressure in the heating system is adequate;

9
- regular maintenance and prevention.
It is recommended that a system log be kept containing the relevant maintenance data.
Damage that may occur due to a malfunctioning system
Component failures (e.str., pumps, valves)
Internal and external leaks (e.str., from heat exchangers)
Reduction in cross-section and flow blockage (e.str., heat exchanger, pipes, pumps can
become clogged due to limescale or corrosion)
Faster wear
Gas cushion formation (cavitation)
Adverse effects due to heat transfer (coatings, sedimentation) and associated noise
(e.str., roaring, flow noise)
THERMAL INSULATION
All heat and cold conductive parts of the piping must be insulated with special means of thermal
insulation in accordance with current standards. The main normative document, which defines the
requirements for thermal insulation, is Order No 1-245 of the Minister of Energy of the Republic of
Lithuania “ON THE APPROVAL OF RULES FOR INSTALLATION OF THERMAL INSULATION OF
EQUIPMENT AND HEAT TRANSMISSION NETWORKS” of 20 September 2017.
ELECTRICAL CONNECTION WORKS
DANGER!
Risk of electric shock! Always disconnect the device from the power supply prior to work on
the electrical system parts.
Remove the top cover of the heat pump by unscrewing the screws on the top of the device.
Connect the power cable to the marked heat pump relay terminals 1, 3, 5, respectively L1, L2, L3
(see, Section: “Heat pump electrical connection diagram”) and connect N and PE conductors to the
marked electrical connection diagram contacts, respectively.

10
Temperature sensors
The temperature sensors for the outdoor and water heater are connected to the terminal blocks,
which are shown in the layout diagram of the control elements (see, Section: “Heat pump electrical
connection diagram”). A two-core 0.5 ÷ 1mm2cable must be routed from the heat pump to the
outdoor temperature installation location.
It is recommended that the outdoor sensor be installed on the north side or in a place that is not
exposed to direct sunlight.
In models without integrated water heater, a two-core 0.5 ÷ 1.0 mm2cable must be routed from
the heat pump to the hot water tank.

Phase sequence relay
The heat pump features a built-in phase sequence relay that ensures that the compressor is
running in the correct phase sequence. The relay is equipped with PWR and OUT indicator lights.
When the heat pump is switched on and the phases are in the correct sequence, the PWR display
lights up yellow and OUT lights up green. If it is not connected properly, the PWR indicator lights up
in yellow and the OUT indicator does not light up. In this case, reset the correct phase sequence so
that the OUT indicator lights up in green.

11
WARNING!
Do not connect anything to the terminals that are dark grey
The phase sequence relay also responds to voltage that is too low or too high. If the
voltage is too low or too high, the compressor operation will stop. When the voltage is
within tolerance again, the compressor operation is resumed.
Control panel
The control panel is installed in the room according to which you want to control the heating
temperature. The panel must be easily accessible in a point about 1.5 m above the floor. An online
5cat network cable must be routed from the heat pump to the control panel mounting location.

HEAT PUMP CLASSIC CONNECTION DIAGRAM
The most popular heating system connection diagram, which is the most cost-effective in
terms of cost and installation. When the hot water is heated to the set temperature, a three-way
valve inside the heat pump switches to home heating, where the heat is transferred to the home in a
low-temperature medium. The manufacturer recommends the use of underfloor heating for this
connection method.
Each heat pump has the ability to connect to the Internet, so you can see the heat pump
settings and control the system remotely.

CONNECTION DIAGRAM FOR HEAT PUMP WITH PASSIVE COOLING
This diagram shows the hydraulic diagram of the heating system when passive cooling is
used. This connection method ensures comfort all year round. The heating system is similar to the
classic one, but in this case it is necessary to lay the pipes to the fan radiators (fan coils). In
addition, a three-way valve is installed on the outdoor circuit, which regulates the direction of glycol
flowing from the outdoor circuit during the warm season. The outdoor circuit cannot be used for
cooling and heating at the same time.
Each heat pump has the ability to connect to the Internet, so you can see the heat pump
