WARNINGS!
Always transport the heat pump in an upright position; exceptionally, it may be
tilted by 35° in all directions. Be careful not to damage the housing or the vital
component parts of the heat pump during transport.
The heat pump is not intended for industrial use and use in premises where
corrosive and explosive substances are present.
The connection of the heat pump to the mains should be performed in
accordance with standards for electrical appliances. An double pole disconnect
switch should be installed between the heat pump and the mains in accordance
with the current wiring regulations.
The heat pump should not be in operation without water in the hot water tank,
because which could result in permanent damage!
The installation should be performed in accordance with all current
regulations and the instructions of the manufacturer. It should be performed by a
professionally trained competent person.
It is necessary to install a safety valve with a rated pressure of 0.6 MPa (6 bar) to
the inlet pipe of the heat pump, to prevent the pressure in the boiler from rising for
more than 0.1 MPa (1 bar).
Water may drip from the outlet opening of the safety valve, so the outlet opening
should be set to atmospheric pressure.
The outlet of the safety valve should be installed facing downwards and in a
non-freezing area.
To ensure proper functioning of the safety valve, the user should perform
regular controls to remove limescale and make sure the safety valve is not blocked.
Do not install a stop valve between the heat pump and the safety valve, because
it will impair the functioning of the safety valve!
Before the beginning of the operation two 90° elbows must be installed to the
top of the appliance (ø125 mm), each facing in the opposite direction. The premises
must be properly ventilated.
The elements in the electronic control unit are live even after pressing the off
field (9) on the heat pump.
If you disconnect the heat pump from the power supply, please drain any water
from the pump to prevent freezing.
Water can be drained from the pump through the water inlet pipe. For this
purpose, it is advisable to install a special element or outlet valve between the inlet
pipe and safety valve.
Please do not try to fix any defects of the heat pump on your own. Call the
nearest authorized service provider.

THE PRINCIPLE OF OPERATION
The heat pump is in fact a thermodynamic heat generator, drawing heat from a low
temperature level (e.g.: heat from the ambient air) to a higher temperature level (e.g.: hot
sanitary water).
The heat drawn from the ambient air, along with the electric energy, generates heating
energy, which is available for heating the sanitary water.

INSTALLATION OF THE HEAT PUMP
The heat pump can be used using the ambient air or air from other premises. The heat
pump must be installed in a frost-free room. When selecting a place for installation,
particular attention should be paid that the selected air intake location is dust free, because
dust has adverse effects on the heat pump performance. When selecting the place of
installation, pay attention to the solidity of the wall –can it take the weight of the heat pump
together with the weight of the water inside the boiler? Take all the necessary precautions
to prevent the operation noise and vibrations from transferring through the walls to the
premises where this would be disturbing (bedrooms, rest areas). Do not install the heat
pump and its air intake in premises with other air consumption appliances (gas boilers,
solid-fuel fireplaces, dust extraction appliances etc.) During installation, please bear in
mind the minimum distances from the wall, ground and ceiling. The condensate outlet from
the heat pump is placed on the bottom left side in the form of a plastic tube with an external
diameter of ø18 mm. This tube should be connected to the external condensate outlet pipe
and led to the sewage system or a container. The quantity of condensate depends on air
temperature and humidity when the heat pump is in operation.
To prevent pressure depression in the building,
fresh air must be regularly supplied to the
premises. The desired rate of air exchange for a
residential building is 0.5. This means that the
entire quantity of air in the building is exchanged
every two hours.
Connecting the heat pump to the same pipeline
as the kitchen extractor fan or taking air out of
several smaller apartments or suites is not
allowed.
Fig. 3: Ventilation
To minimize the transfer of noise and vibrations
through walls into the premises where this would
be disturbing (bedrooms, rest areas), please take the following measures:
- install flexible joints for hydraulic connections
- install a flexible tube for the pipeline of inlet/outlet air
- plan vibration insulation for wall openings
- plan noise dampers for inlet/outlet air
- pipelines for inlet/outlet air should be attached using noise dampers
- plan vibration insulation against the wall

a) Operation using ambient air
In this type of operation, the device heats domestic water
using only the amount of energy generated by the air from
the room where the device is installed. The heat pump
must be installed in a ventilated, frost-free room, possibly
in the vicinity of other heating sources. For optimal
performance of the heat pump, we recommend a
sufficiently large and well ventilated room with the
temperature ranging between 15 °C and 25 °C. It is vital
to ensure sufficient intake of air in the room. Elbows must
be installed on the heat pump and turned so that they
prevent the mixing of air. Heat losses are greater in
premises with colder air.
b) Operation using air from other premises
In this type of operation, the heat pump uses air from
other premises via a pipeline system. It is advisable to
insulate the pipeline system to prevent the formation of
condensate.
In case of using air from outside, the external part must be
covered so as to prevent the intrusion of dust or snow into
the appliance. Besides the drag in the pipes and elbows, the user should be aware that
increased drag also increases noise levels.
In case of using air from outside, the user should adhere to the minimum diameter of the
pipes ø125 mm or □150x70.
To make sure the operation of the pump is effective at all times, you can install dampers to
take air from the premises and then return it either to the premises or outside. If the
temperature of air is under -7 °C, heaters for the heating of domestic water are switched
on. The heat pump operates in reserve mode.

PRESSURE LOSS IN CASE OF USING THE PIPELINE SYSTEM
In planning the pipeline system for the inlet and outlet of air to and from the heat pump, the
key element is to take into account the aerodynamic character of the fan which also causes
the loss of static pressure.
Presentation of the diagram of aerodynamic characteristics for different speeds of
the fan
The diagram (Diagram 1) includes aerodynamic characteristics of the operation of the fan.
The top line represents the curve of air flow depending on the pressure drop at maximum
speed of the fan (100 %). The bottom line represents the operation of the fan at minimum
speed (40 %). The curves between (60 %, 80 %) represent the aerodynamic
characteristics at lowered revolutions of the fan. The bottom line that lies between points
(0,0) and (340,50) represents the internal drop of static pressure created by the evaporator
alone, without overloading the pipeline system. This pressure drop cannot be eliminated.

- Operating area with a normal air flow with respect to the pressure drop and fan setting.
- Area of more efficient use –volumetric flow of air is higher here, which requires a lower pressure drop
(channel system with minimum pressure drop). Fan is set to higher speeds.
Diagram 1: Aerodynamic characteristics
Air inlet and outlet pipeline system
When connecting the sanitary heat pump to an existing pipeline system, we use the basic
pipe elements that we connect into a pipeline system for air inlet and outlet. The air
pipeline should consist of round pipes with an inner diameter of ø125 mm, or rectangular
pipes with a cross section of □150x70 mm.

Calculationof pressure drops
The values of total static pressure drop can be calculated by adding up the losses from
individual elements built into the air pipeline system and the internal static pressure. The
values of static pressure drops of individual elements (static pressure drops of elements
relate to the internal diameter ø125mm or □150x70mm) are shown in Table 1.
