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

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.
All cables must be secured against displacement with cable clips. Following the connection and
fixing of cables, the plastic covers of both indoor and outdoor units are fixed on place and
secured with screws taking care to dispose freely cables; gauges and the thermal switch
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
harms shall not be covered by the manufacturer or seller warranty liabilities and shall be at the
expense of those violating the instructions.
Only qualified workers shall be allowed to connect the device to power supply network and
check its functionality.
CONNECTION OF HEAT PUMP WATER HEATERS WITH SOLAR HEAT EXCHANGER
For connecting the cable to the terminals follow the steps: remove carefully the water heater
(indoor unit) plastic cover, in order to avoid dividing the unit conductors. Connect the phase
conductor of the power supply cable to the terminal marked A1 (or L, depending of
modification), as shown on the electric schema on Fig. 14, then the neutral to terminal
В
1 (or
N), and the earthling to the safety terminal (the screw on the flange bracket) marked with
earthling sign. The power supply cable must be connected so that current carrying connectors
be stretched before stretching the protective earth conductor in cases where the cable
unlooses.
The connection of the outdoor unit power cable to the indoor unit column terminal marked as
‘EXT’ shall take place according the electric circuit schema on Fig. 14 by connecting the phase
conductor to the terminal marked L, the neutral conductor to terminal marked N, and the
14
