IT IS ABSOLUTELY FORBIDDEN
to proceed to next step in connection process before
completely removing the cause of the fault!
WARNING!
Failure to comply with the procedure for connection to plumbing installation may
cause filling water tank and fault of the water heater, and in cases where the combined valve is
still not installed or installed in wrong way, it may destroy the water tank, the premise and/or
cause other tangible and intangible losses. . 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.
WARNING!
The combined check-safety valve is one of the safety components providing for
water heater harmless operation. It is absolutely FORBIDDEN to use water heater equipped
with defective or removed/not installed combined valve!
Only qualified workers shall carry out the connection of the water heater to the water supply
network.
CONNECTING THE APPLIANCE TO THE POWER SUPPLY NETWORK
WARNING!
Do not proceed to connect the appliance to the power supply grid before being sure
that its water tank is filled with water! Check it!
The heat pump operated water heater is provided with electricity protection Class
І
.
Water heater power supply takes place through separate circuit of three-wire cable with 2,5 mm
2
section of each wire (phase, neutral and earthling). Therefore if the in-wall cable is two-wire, a
qualified electrician must add a third, protective conductor with no interruption on its track from
the switchboard to the water heater. If the earthling conductor/wire has intermediate
connections, latter must be secured against loosening. Otherwise the appliance shall not be
correctly earthed and it shall reduce its safety.
It is imperative that the phase circuit is equipped with 16
А
fuse.
CONNECTION OF HEAT PUMP WATER HEATERS WITHOUT 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. 13, 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.
