All cables need to be secured against shifting using cable clamps. After connecting and fastening the
cables, the plastic covers of the indoor and outdoor unit are placed in their places and secured with
the screws, taking care to free placing of the cables, sensors and capillary tube of the thermal switch.
After connecting the appliance to the electrical installation it is necessary to check its functionality.
WARNING
! Failure to comply with the requirements for connection to the electrical installation
will reduce the safety of the appliance, which prevents it from being used. The consequences
are not within the scope of warranty obligations of the manufacturer and the seller and are at
the expense of the persons that failed to comply with the requirements of this instruction.
WARNING
! If the power supply cable or one of the interconnecting cables of the heat pump
system is damaged, it must be replaced by the manufacturer, its service representative or a
person with a similar qualification in order to avoid danger.
WARNING
! The appliance must be connected to the electrical system and checked for its
functionality by authorized persons only.
The manufacturer has thus installed the water heater to operate without a UPS. If it is necessary to
provide power supply from UPS, it is necessary on the terminal block marked as "
Terminal for UPS
"
to remove the cables (bridges) connecting the terminals
L
out
with
L
in
, and
N
out
with
N
in
. The UPS is
connected to the disconnected terminals. The power supply cable to the UPS is connected to the
terminals
L
out
(phase) and
N
out
(zero). The output of the UPS is connected to the terminals L
in
(phase)
and N
in
(zero)
WARNING
! It is imperative that you properly connect the UPS cables and phase and neutral
compliance!
When removing the UPS, it is necessary to reinstall the bridge cables connecting the terminals
L
out
with
L
in
, and
N
out
with
N
in
.
WARNING
! If the UPS is incorrectly connected or the bridge cables are incorrectly reinstalled,
the electrical block will not work, it may also be damaged and there is an increased risk of
electric shock!
ELECTRICAL CONNECTION OF THE CIRCULATION PUMP AND THE SOLAR
PANEL SENSOR FOR APPLIANCES WITH HEAT EXCHANGER
One of the temperature sensors (included in the set and with wires with teflon cover) designed for the
solar panel, type
Pt1000
is connected to the terminal marked
S3
on the electronic control board of
the indoor unit. If necessary, the sensor cables are elongated to the required length. The electrical
connection of the controlled circulating pump intended for the pump circuit circulating between the
solar panel and the serpentine of the indoor unit is made by connecting the phase and neutral
conductor of the power supply cable to the terminal marked with
PUMP1
on the indoor unit board and
the protective earthing of the pump is made by connecting the earthing wire of the power supply
cable to the protective terminal of the water tank marked with the protective earthing sign. All cables
need to be secured against shifting using cable clamps. After connecting and fastening the cables,
the plastic covers of the indoor and outdoor unit are placed in their places and secured with the
screws, taking care to free the cables, sensors and capillary tube of the thermal switch.
ATTENTION!
The power output of the pump electric motor must be less than 200 W!
