The connection of the heat pump to the mains should be performed in
accordance with standards for electrical appliances. An all-poles disconnect
switch should be installed between the heat pump and the mains in accordance
with the national installation standards.
The heat pump should not be in operation without water in the hot water
tank, because of danger of destruction of the compressor!
The installation should be performed in accordance with the valid
regulations and the instructions of the manufacturer. It should be performed by
a professionally trained installation expert.
It is necessary to install a safety valve with a rated pressure 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 boiler 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 authorised service provider.

THE PRINCIPLE OF OPERATION
EN
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
EN
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.
If the heat pump is installed in a frost-free
room and the temperature is under 7 °C, the
heat pump operates in the normal mode of
operation.
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 (purple) line represents the curve of air flow depending on the
pressure drop at maximum speed of the fan (100 %). The bottom (brown) 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 (red) 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.
10
EN
Pressure difference [Pa]
Air flow [m³/h]
- 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.
- Operating area with a normal air flow with respect to the pressure drop and fan setting.
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.
Fig. 6: Schematic demonstration of the basic elements in a pipeline system for inlet
and outlet of air
11
Calculation of pressure drops
The values of total static pressure drop can be calculated by adding up the losses
EN
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 no. 2.
Type of element
a.) Spiral ribbed pipe
b.) Rectangular pipe □150x70 mm
c.) Rectangular elbow - horizontal 90° 5 Pa
d.) Elbow 90° 4 Pa
e.) Angular reducer ø125 to □150x70 5 Pa
f.) Rectangular elbow - vertical 90° 5 Pa

Table 3: Example of pressure drop calculation
Note:
As mentioned above, the total loss of static pressure, which can be calculated by
adding up the losses of individual elements built into the pipeline system, may not
exceed 95 Pa. If they do, the values of COP start dropping more dramatically.
DETERMINING THE FAN SETTING
When pressure drop is determined, select the mode in which the fan will operate.
This determines the speed of the fan. The mode is selected using Diagram no. 1,
which shows the aerodynamic characteristics of the fan depending on the air flow and
pressure drop in the pipeline*.
Note:
*Pressure drop in the pipeline – in diagram 1 this is marked as pressure difference.
Zone of operation of the sanitary heat pump
On diagram 1 there are two zones of operation of the sanitary heat pump among the
curves:
Number of
elements
p (Pa) p (Pa)
25
(at 150 m3/h)
The dark green zone represents the area of use with higher efficiency. The
volumetric air flow is higher in this zone, which requires a lower pressure drop
(channel system version with minimum pressure drop).
The light green zone represents the area of use with lower air flow in relation to the
pressure drop and fan setting.
Noise
Like the aerodynamic characteristics rise from the lowest to the highest, the noise
increases as well. Between the aerodynamic characteristics 80% and 100 % there is
a zone with increased noise.
Checking the calculation of pressure drop
Determining the aerodynamic characteristics based on the calculation of pressure
drop while taking into account individual elements of the pipeline and air flow is an
iteration. Once the aerodynamic characteristic has been determined and set, we must
measure the air flow in the pipeline. If the air flow does not correspond to the
ventilation system, we select the next higher or lower aerodynamic characteristic that
corresponds to the ventilation system.
EN
13
Selecting the operating point of the fan for the ventilation system
EN
When determining the speed of the fan, we must know the maximum air flow for
ventilation and pressure drop caused by the pipeline. In Diagram 1, find the desired
air flow and draw a vertical line, then draw a horizontal line at the pressure drop that
you have calculated (based on the existing pipeline). Select the fan characteristic
curve that lies the closest to the point where the lines cross.
Example of selecting the aerodynamic characteristic
In diagram 3 at air flow of 150 m³/h draw a vertical line. The pipeline represents 70
Pa of pressure drop, which is added to the below (red) line**. Total pressure drop is
thus 90 Pa. Draw a horizontal line at the pressure drop of 90 Pa. The point where the
lines meet lies on the curve that corresponds to 60% speed of the fan. This is the
standard setting of the fan that has also been preset by the manufacturer.
Note:
**Line, represents the internal static pressure drop created by the evaporator.

CONNECTION TO WATER SUPPLY MAINS
Water inlet and outlet on the heat pump are marked with colours. Cold water inlet is
marked with blue, and warm water outlet is marked with red. The heat pump is
designed for connection to indoor water supply mains without using the relief valve if
the pressure in the supply mains is lower than 0.6 MPa (6 bar). If the pressure is
higher, a relief valve needs to be installed so as to provide that the pressure at the
inlet to the hot water tank does not exceed the nominal pressure.
Installing a safety valve is mandatory in order to assure safe operation. The valve
prevents an increase of the pressure in the boiler by any more than 0.1 MPa (1 bar)
above the rated pressure. The outflow nozzle on the safety valve must have an outlet
into the atmosphere. To assure correct operation of the safety valve, the valve must
be regularly checked.
When checking the valve, push the lever or unscrew the nut of the valve (depending
on the type of the valve) and open the drain from the safety valve. Water must flow
from the valve nozzle, showing that the valve operation is faultless. During the
heating of water, the water pressure in the hot water tank is increased up to the level
preset in the safety valve. Since the system prevents backflow of water into the water
supply mains, water may be dripping from the outlet opening on the safety valve. The
dripping water may be drained via trap into the drains; the trap is mounted under the
safety valve. The outlet pipe, which is mounted under the safety valve, must be
directed downwards, in a place with a temperature above freezing.
If the installation does not allow draining of the water from the safety valve into the
drains, dripping can be avoided by installing an expansion vessel onto the heat pump
inlet pipe. The volume of the expansion vessel must be ca. 3% of the hot water tank
volume.

SERVICE AND MAINTENANCE
If installed and used correctly, the heat pump will last for years without service.
The exterior of the heat pump should be cleaned with a mild detergent solution. Do
not use solvents or abrasive cleaning agents.
If the heat pump was exposed to dust, evaporator lamellas might become blocked,
which can have a detrimental effect on the functioning of the heat pump. In this case
the evaporator should be cleaned. The cleaning of the evaporator must be carried out
by an authorised service provider.
By performing regular service inspections you can ensure faultless operation and a
long life span of the heat pump. The tank corrosion warranty applies only if the
prescribed regular anode inspections have been performed. The interval between
individual inspections should not be longer than 36 months. Inspections must be
carried out by an authorised service provider that logs each inspection on the
product’s warranty sheet. The service provider inspects the wear and tear of the anticorrosion protective anode and cleans the limescale that accumulates inside the tank,
depending on the quality, quantity and temperature of the water used. Service
providers will also provide you with the following inspection date, depending on the
state of the heat pump.
Before calling your service provider, check the following:
Is everything OK with the power supply network?
Is the air outlet obstructed?
Is ambient temperature too low?
Can you hear the operation of the compressor and fan?
Pipeline system pressure drop
Do not try to eliminate malfunctions by yourself, call your nearest authorized
service provider!

FUNKTIONSPRINZIP DER WÄRMEPUMPE
DE
Die Wärmepumpe ist ein thermodynamischer Wärmegenerator, der die Wärme aus
dem niedrigeren Temperaturniveau (z.B. Wärme der Raumluft) auf ein höheres
Temperaturniveau anhebt (z.B. warmes Brauchwasser).
Diese, der Raumluft entzogene Wärme, schafft zusammen mit der Antriebsenergie
(elektrische Energie) Wärmeenergie, die zum Erwärmen des Brauchwassers zur
Verfügung steht.
