Under the outdoor protection cover marked as
В
on Fig. 1 you will find the terminals marked ‘
Т
R G’. For each selected colour and corresponding letter of the indoor unit must be connected
the terminal with the same letter and colour of the outdoor unit.
WARNING!
Incorrect connection of the communication cable wiring may damage the units!
According to their purpose use the following cables:
Purpose
Cable
Type
Power supply cable to the unit
3G 2.5mm2
H05VV-F
Power supply cable to outdoor unit
3G 1.5mm2
H05RN-F
Communication
3G 0.75mm2
H05RN-F
WARNING!
Under the indoor unit plastic cover you will find its upper gauge. It is a conductor
long two meters. The gauge must be installed within the probe located in the indoor unit left
upper side. The position M is marked on Fig. 1 and next to it is glued a sticker ‘Coupling
thermostat.’ When installing the gauge it must be secured against unauthorized extraction and
transfer. If it is not installed or due to specific reasons the gauge is extracted, the unit shall not
operate correctly.
The manufacturer has installed the water heater so that it can operate without UPS device. If it
is necessary to connect power supply from a UPS device, on the column labeled “UPS terminal”
remove the wires (bridges) connecting terminals L
out
with L
in
and N
out
with N
in
, indicated on Fig. 1
by a broken line. Connect the UPS device to the released terminals. Connect the UPS power
cable to terminals L
out
(phase) and N
out
(zero). Then connect the UPS exit to terminals L
in
(phase) and N
in
(zero).
WARNING! It is imperative to connect properly the UPS outlet cable to the unit terminal,
i.e. to comply with phase and zero!
When removing power supply from the UPS device reconnect the bridging wires to the column
“UPS terminal,” respectively L
out
to L
in
and N
out
to N
in
.
ATTENTION! In case of incorrect UPS connection or improper reconnection of the bridge
links the electronic control unit shall not operate and it is even possible to damage it,
thus causing an increased risk of electric shock!
It is necessary to secure against displacement all power cord to the water heater circuit by using
the cable brackets. Following the connection and fixing of power cables to the electronic unit,
place the plastic covers of the indoor and outdoor units on their locations and screw them
carefully to leave inside the boxes the cables free, as well the gauges and the thermostat
capillary pipe.
WARNING!
IT IS MANDATORY
to install within the device power supply circuit a unit providing
insulation of all poles in case of overvoltage of type
ІІІ
. The wires in the circuit between this unit
and the input terminals of the appliance must not be interrupted by other circuit breaker or fuse.
If the appliance in installed in a bathroom, the disconnecting unit must be located out of the
premise.
Following the appliance connection to the power supply network it is necessary to check its
functionality.
WARNING!
Failure to comply with requirements for connection to the power supply grid shall
harm device safety, thus restricting the right to use it. In such cases eventual damages and
