THE PRINCIPLE OF OPERATION
The heat pump is
in
fact athermodynamic heat generator, drawing heat from alow
temperature level (e.g.: heat from the ambient air) to ahigher 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.

IINSTALLATION 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
afrost-free room. When selecting aplace 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
aplastic tube with an external
diameter
of
018 mm. This tube should be connected to the external condensate
outlet pipe and led to the sewage system or acontainer. 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 aresidential
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 aflexible 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
aventilated, frost-free
room, possibly
in
the vicinity
of
other heating
sources. For
optim~1
performance
of
the heat
pump, we recommend asufficiently 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
afrost-free
room and the temperature is under
7°C,
the
heat pump operates
in
the normal mode
of
operation.

Operation
using
air
from
ott1er
premises
In
this type
of
operation, the heat pump uses air from other premises via apipeline
system. It
is
advisable to insulate\the pipeline system to prevent the formation at
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 0125 mm or o150x70.
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
domestir,
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.

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 apipeline system for air inlet and outlet.
The air pipeline should consist of round pipes with
an

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

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: a .
*Pressure drop in the pipeline -
in
diagram 1
thiS
is'marked as pressure difference,
Zone
of
operation
of
the
sanitary
heat
pump
On diagram 1there are two zones
of
operation
of
the sanitary heat pump among the
curves:
•The dark green zone represents the area
of
use with higher efficiency. The
volumetric air flow is higher
in
this zone, which requires alower 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
azone 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.
13
I
•Selecting the operating point of the fan for the ventilation system
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 avertical line, then draw ahorizontal 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 3at airflow of 150 m3/h draw avertical 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 ahorizontal 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:

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, arelief 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 asafety 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
aplace with atemperature 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.

•CONNECTING THE HEAT PUMP TO THE POWER'SUPPLY NETWORK
Before connecting to the power supply
network, install apower supply cord
in
the heat pump, with amin. diameter of
1.5 mm2(H05VV-F
3G
1.5 mm2
).
To
do
this, remove the protective cover from the
heat pump. The cover
is
attached using
two screws (Fig. 9). Connecting the heat
pump to the power supply network must
take place
in
accordance with the
standards for electric appliances. To
comply with the national installation
regulations, an all poles disconnect
switch must be installed between the heat
pump and the power supply network.
