defined concerning mini-maxi tolerance limits of the safety valve. If it exceeds this
value, pressure reduction device should be connected in front of the safety valve.
The safety valve is not an accessory of the appliance.
IT IS FORBIDDEN TO BUILD WATER PIPELINE FITTING BETWEEN THE VALVE
Before mounting the valve, the cold water pipeline must be flushed thoroughly,
in order to avoid any damage caused by any possible pollution. The combined safety
valve contains a one-way valve. Therefore, it is not needed to mount a separate one-
way valve. During the heating, the expanding water has to leak through the drainage
pipe branch of the combined safety valve. During installation of the valve, one should
pay attention to ensure that this leaking remains visible.
IT IS FORBIDDEN TO CLOSE THE DRAINAGE PIPE BRANCH OR TO DIVERT
If the pipeline system pressure exceeds the value of 0.6 MPa – only in a
temporary way -, a pressure reduction valve has to be mounted in front of the hot
water tank, at the location of item
No. 3 as described in Figure 7.3.-1. In case of lacking pressure reduction valve, the
safety valve will leak besides heating under this pressure. It is the task of the user to
purchase and mount the pressure reduction valve. If the combined safety valve is
connected to the hot water tank without the reducing device, in order to discharge the
hot water tank, a discharge faucet or valve should be mounted to the cold water pipe
of the appliance, adding a standard T-shaped fitting. It is the task of the user to
purchase the valve (faucet). An arbitrary number of taps and mixing faucets can be
mounted on the hot water tank. It is rational to block the flow back of the hot water
through the outlet towards the cold water pipeline system by mounting a one-way
valve in the cold water pipe in front of the taps. A closing valve needs to be mounted
in the cold water pipeline leading to the tank in front of the fittings (combined safety
valve, one-way valve, etc.) With the help of this closing valve, both the hot water tank
and the water pipeline fittings can be disconnected from the water pipelines system
(in case of failure or other maintenance work).

Electric connection

3.6.
1. The hot water tank should be connected to the electric system only through
permanent connection. It is forbidden to apply any wall socket.
2. The current of the electric system has to be connected to the hot water tank
through an all-pole disconnection device, which has at least 3mm separation distance
in all poles.
3. The required diameter per string of the electric system wire with 3 strings is:
2.5 mm2 – 4 mm2, depending on performance as described on the data table.
The wires adequate for connection to the electric system are the following:
Connection with wire protection tube is not allowed.
4. The connection wire and the wire with green/yellow colour mark have to be
connected in the terminal block. The plastic wire driver marked with a label located at
the lower part of the cover of the fitting house has to be broken out. ("Break out for
connection") The overhang part of the rubber wire driver, which is placed in the bag
attached to the appliance, has to be cut, then the wire driver has to be stitched to the
electric system wire. The connection wire has to be connected in the terminal block of
