Where: 1 – input pipe, 2 – safety valve (0.8 MPa), 3 –
reduction valve (if the water supply pressure exceeds
0,6 MPa), 4 – stop valve, 5 – bell-mouth discharge to the
sewer, 6 – hose; 7 - Drain water tap.
Upon connecting the water heater to the water supply
system, take care of the indicative color markings /rings/
of the pipes:
BLUE - for cold /in-flowing/ water,
RED - for hot /out-flowig/ water.
The mounting of the safety return-valve supplied with the
water heater is obligatory. The safety return-valve must
be installed on the cold water supply pipe, according to
the arrow stamped on its body that indicates the supplied
water direction.
Exception: If the local regulations (norms) require the
usage of another protection valve or mechanism (in
accordance with EN 1487 or EN 1489), then it must be bought
additionally. For mechanisms operating in accordance with
EN 1487 the announced operational pressure must be no
more than 0.7 MPa. For other protection valves, the pressure
at which they are calibrated must be 0.1 MPa lower than the
one marked on the appliance's sign. In these cases the safety
valve which the appliance is supplied with should not be
used.
ATTENTION! Other type of stopping armature is not
allowed between the protection return valve (the
protective device) and the appliance.
ATTENTION! Any other /old/ safety return-valves may
lead to a failure of your appliance, therefore they
must be removed.
ATTENTION! Fixing the safety return-valve to threads
longer than 10 mm is not allowed, as it could
damaged the valve and could make the use of your
appliance dangerous.
ATTENTION! The safety valve and the pipe between the
valve and the water heater must be protected from
freezing. During hose draining - its free end must be always
open to the atmosphere (not to be immersed). Make sure that
the hose is also protected from freezing.
The electric water heater is filled with water by opening
the tap on the cold water supply system and the tap on
the hot water mixing faucet. After the filling process is
complete, a constant stream of water should flow from the
water-mixing faucet. Now you can shut the hot water tap
on the mixing faucet.
When you must empty the water heater, you should first
cut it off the power supply.

In case that the pressure in the water mains is over the
value pointed out in the above paragraph I, then it is
necessary to assemble a pressure reduce valve, otherwise
the water heater would not function properly. The

arising out of the appliance's improper use.
3. Water heater's electrical connection (fig.3)
ATTENTION! Before you switch the power supply,
make sure the appliance is full of water.
