IV. DESCRIPTION AND PRINCIPLE OF OPERATION
EN
The appliance consists of a body, flange, plastic control
panel, safety return valve.
1. The body consists of a steel reservoir (water tank)
and plastic housing (outer shell) with thermal insulation
placed in-between, and two pipes with thread G ½",
for cold water supply (marked with a blue ring) and
hot water discharge (marked with a red ring). The inner
reservoir is made of steel proved against corrosion by a
special glass-ceramic coating
2.
The flange is fitted with electric heater and
magnesium anode protector. The flange is fixed to the
water tank with bolts.
The electric heater heats the water in the tank and
is controlled by the thermostat, which automatically
maintains the preset temperature.
The plastic control panel incorporates: switch (depending
on model), adjustable thermostat (depending on model),
and thermal cut-out and control lamps.
The thermal cut-out is a device, which switches the heater
off the power supply when the water temperature reaches
excessive values. If this device is actuated, you should call a
service station.
The signal lamps (depending on model) on the control
panel indicate the current mode of the unit.
The magnesium protector provides additional anti-
corrosion protection to the internal tank for heaters fitted
with glass-ceramic coating.
3. The safety-return valve prevents the appliance's
complete emptying in the event of cold water supply
interruption. The valve protects the appliance from
pressure increases higher than the allowed value during
heating (! pressure will increase when temperature
increases), by releasing the excess pressure through the
drain outlet. Water dropping out through the drains
during the warming process is a normal event that must
be taken into consideration when the boiler is installed.
ATTENTION! The safety-return valve cannot protect
the appliance in the event of water mains pressure in
excess of the acceptable pressure stated for the appliance.
V. INSTALLATION AND SWITCH ON
ATTENTION! Qualified technicians must perform all
technical and electrical assembly works. Certified
technician is the person who possesses the relevant
competence in accordance with the legislation of the
respective country.
1. Installation
We recommend installation of the device at close
proximity to locations where hot water is used, in order
to reduce heat losses during water transportation. The
selected location must exclude the possibility of water
spray originating from the showerhead or other water
contacts.

Instructions for use and maintenance
The appliance is affixed to a wall by means of mounting
brackets attached to the unit's body. Two hooks are
used to fix the appliance (min. Ø 6 mm) firmly on the
wall (included in the mounting set). The bearing plank
construction for boilers installed above / under sinks is
universal and allows the space between hooks to vary
between 96 and 114mm. (fig.2)
IMPORTANT: The type of boiler designed to be installed
UNDER / ABOVE a sink is marked on the appliance.
Boilers designed for installation above sinks are assembled
in such a manner that the outlet/inlet pipes are pointed
downwards (to the floor of the premise). Boilers designed for
installation under sinks are assembled in such a manner that
the outlet/inlet pipes are pointed upwards (to the ceiling of
the premise).
For clear understanding of wall installation schemes, please
refer to fig.2 (A above sink and B under sink).
ATTENTION! In order to prevent injury to user and
third persons in the event of faults in the hot water
supply system, the appliance must be mounted in premises
outfitted with floor hydro insulation and sewer drainage.
Don't place objects, which are not waterproof under the
appliance under any circumstances. In the event of mounting
the appliance in premises without floor hydro insulation, a
protective tank with a sewer discharge drainage must be
placed under the appliance.
Notice: the set does not include a protective tub and the
user must select the same.
2. Water heater connection to the water supply system
Fig.4a - installation scheme above sink
Fig.4b - installation scheme under sink
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.
