This appliance can be used by children aged from 8
years and above and persons with reduced
physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given
supervision or instruction concerning use of the appliance
in a safe way and understand the hazards involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be made by
children withoutsupervision.
IV. DESCRIPTION AND PRINCIPLE OF OPERATION
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 enamel coating.
2. The flange is fitted with electric heater and magnesium
anode protector. 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: 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 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(7.5
bar/0.75 MPa) 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 from water supply pressure
exceeding the pressure indicated for the appliance. In the
event of higher water supply pressure (>0.6 MPa) there
will be constant leaks from the appliance drains.

V. INSTALLATION AND SWITCH ON
ATTENTION! Qualified technicians must
perform all technical and electrical assembly
works.
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.
The appliance is affixed to a wall by means of mounting
metal brackets. The brakets should be affixed with the
expansion bolts first - see pic. 1.
IMPORTANT: 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,
