The presence of other (old) safety return-valves
may lead to a breakdown of your appliance and
they must be removed.
The attaching of the safety return-valve to threads
longer than 10 mm is not allowed; otherwise this
may damage the valve and therefore pose danger
to your appliance.
For water heaters for vertical mounting, the safety
valve has to be connected to the incoming pipe
with the safety plastic panel of the appliance
being taken off. After installing the appliance it
should be in the position shown in Fig.2.
The safety-return valve and the pipe between the
valve and the water heater must be protected from
freezing. In case of 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.
To fill the water heater with water first open the hot-
water tap of the water-mixing faucet. Then open the
cold-water tap of the water-mixing faucet. The appliance
is full when a constant stream of water flows from the
water-mixing faucet. Then close the hot water tap.
When you have to empty the water heater, first you
must cut off its power supply. Then stop feeding water
to the appliance. Open the hot-water tap of the water-
mixing faucet. Open tap 7 (fig. 4) in order to drain the
water from water tank. If there is no such tap built in the
pipeline, than the water can be drained in the following
ways:
•
For models with a safety valve with a lever – lift the
lever and the water will flow out of the drainage
opening of the valve
•
For models with a safety valve without a lever – the
water heater can be drained directly from the inlet
pipe of the water tank, having it disconnected from
the water mains prior to this
When removing the flange, it is normal for several litres
of water, which have remained in the water tank, to be
discharged.
Measures must be taken to prevent damages by
the discharged water.
If the pressure in the water mains piping exceeds
the value specified in paragraph I above, a pressure-
reducing valve must be installed, otherwise the water
heater will not be correctly operated. The manufacturer
will not bear any liability for problems arising from
improper operation of the appliance.

mains
Make sure the appliance is full of water before
switching on the electrical power supply.
For models with a power cord with a plug,
3.1.
connection to the electrical mains is done by
inserting the plug into an electrical socket.
Disconnection from the electrical mains is done by
unplugging the power cord from the socket.
The electrical socket must be properly connected
to a separate current loop that is provided with a
safety fuse. It must be earthed.

without a plug
The appliance has to be connected to a separate current
loop of the stationary electrical installation, and also
it has to be provided with a safety fuse with nominal
current of 16A (20A for power > 3700W). The connection
has to be permanent – with no plug connectors. The
current loop has to be provided with a safety fuse and
with an inbuilt device which would disconnect all poles
in case of category III overvoltage.
The connecting of the conductors of the supply cord of
the appliance has to be carried out in the following way:
•
conductor with brown insulation – to the phase
conductor of the electrical installation (L)
•
conductor with blue insulation – to the neutral
conductor of the electrical installation (N)
•
conductor with yellow-green insulation – to the
safety conductor of the electrical installation (
Water heaters without power cord
3.3.
The appliance has to be connected to a separate current
loop of the stationary electrical installation, provided
with a safety fuse with nominal current of 16A (20A
for power > 3700W). Connection is done using copper
single core (rigid) conductors – cable 3 x 2.5 mm² for a
total power of 3000W (cable 3 x 4.0 mm² for power >
3700W).
In the electrical circuit providing power supply for the
appliance there has to an inbuilt device which would
disconnect all poles in case of category III overvoltage.
To install the power supply wire to the water heater,
remove the plastic cover (Fig.2a).
Connect the power supply wire in compliance with the
marking on the terminals, as it follows:
•
the phase – to marking A or A1, L or L1;
•
the neutral – to marking N (B or B1 or N1)
•
The safety wire must be connected to the screw
joint marked with
After installation, put the plastic cover back in its
place!
