III. DESCRIPTION AND PRINCIPLE OF OPERATION
The appliance is designed to operate in regions where the
water hardness is not more than 10°dH. In case that it is
installed in a region where the water is harder it is possible
that limestone precipitation accumulate very fast. This
can cause a specic noise during heating, as well as fast
damaging of the electrical part. For regions with harder
water yearly cleaning of the limestone precipitation in the
appliance is recommended, as well as usage of not more
than 2 kW of heating power
The appliance consists of a body, ange, 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 ange is tted with electric heater and magnesium
anode protector. The ange is xed 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
o 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 tted
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.
IV. INSTALLATION AND SWITCH ON
Attention! Improper installation and connection of the
appliance may make it hazardous for the health and life
of consumers. It may cause grievous and permanent
consequences, including but not limited to physical injuries and/or
death. Improper installation and connection of the appliance may
also lead to damage to the consumers’ property /damage and/ or
destruction/, or to that of third persons, as a result of, but not
limited to ooding, explosion and/or re.
Installation, connection to the main water and power supply, and
putting into operation must be carried out by certied electricians
and technical personnel certied in installation of this category of
appliances, who have obtained their license in the state where the
installation and commissioning of the appliance are carried out,
and in compliance with its local legislation.
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 axed to a wall by means of mounting
metal brackets. The brakets should be axed with the
expansion bolts rst - see pic. 3.
IMPORTANT: The appliance 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 g.3.
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
outtted with oor 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 oor 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.
