with the valid regulations and according to the in-
structions of the manufacturer and by qualified
staff.
Connection only to fixed installed cables! The hard-
wired electrical installation must be provided with a
disconnect device with a contact grap of at least 3
mm at each pole (e.g. automatic circuit breaker)!
The size indicated on the rating plate maximum
water pressure must be exceeded at any time.
Open never the device to have interrupted previ-
ously the power to the device permanently.
Repairs to the appliance or any other interven-
tions, may only be performed by qualified persons
or the after-sales customer service.
The device must be reliably connected to a protec-
tive earth.
In case of breakdown immediately switch off the
fuse.
If leaks on the unit, close the water supply immedi-
ately.

ATTENTION!
Connection only to fixed installed cables! The
hardwired electrical installation must be provided with a
disconnect device with a contact grap of at least 3 mm
at each pole (e.g. automatic circuit breaker)!
It is advisable to provide for the power supply a
separate circuit (16 A).
Installation should be carried out in accordance
with the valid regulations and according to the in-
structions of the manufacturer and by qualified
staff.
Ensure that the connection cable does not touch
the hot water pipe.
In a closed, pressurised system of installation, it is
obligatory to install a safety valve on the inlet pipe
with a rated pressure of 0.6 MPa (6 bar), 0.9 MPa
(9 bar) or 1.0 MPa (10 bar) (see the label), which
prevents the elevation of pressure in the boiler by
more than 0.1 MPa (1 bar) above the rated pres-
sure.
Water may drip from the outlet opening of the
safety valve, so the outlet opening should be set to
atmospheric pressure.
The outlet of the safety valve should be installed
facing downwards and in a non-freezing area.
To ensure proper functioning of the safety valve,
the user should perform regular controls to remove
limescale and make sure the safety valve is not
blocked.
Do not install a stop valve between the water
heater and the safety valve, because it will impair
the pressure protection of the heater!
Before connecting it to the power supply, the water
heater must be filled with water!
The heater is equipped with an additional thermal
cut-off for protection in case of failure of the operat-
ing thermostat. In this case, however, the tempera-
ture of the water in the heater can reach up to 130
°C according to the safety standards. During the
water supply installation, the possibility of tempera-
ture overloads should be taken into account.
If the heater is to be disconnected from the power
supply, please drain any water from the heater to
prevent freezing.
Water can be drained from the heater through the
boiler inlet pipe. For this purpose it is advisable to
install a T- element with an outlet valve between
the inlet pipe and safety valve.
Please do not try to fix any defects of the water
heater on your own. Call the nearest authorised
service provider.
