should be left open to the atmosphere. Measures should be taken to lead
and collect the leakages in order to prevent damages, ensuring that this is in
conformation with the requirements described in p. 2 in paragraph V.
•
The valve and the elements linked to it must be protected from freezing.
•
During the heating the appliance could produce a hissing noise (the boiling
water). This is common and does not indicate any damage. The noise gets higher
with the time and the reason for this is the accumulation of limestone. To remove
the noise the appliance must be cleaned from limestone. This type of cleaning is
not covered by the warranty.
•
In order to secure the water heater's safe operation, the safety return-valve
must undergo regular cleaning and inspections for normal functioning /the
valve must not be obstructed/, and for the regions with highly calcareous
water it must be cleaned from the accumulated lime scale. This service is not
provided under warranty maintenance.
All alterations and modifications to the water heater's construction and
electrical circuitry are forbidden. If such alterations or modifications are
established during inspection, the appliance's warranty shall be null and
void. Alterations and modifications shall mean each instances of removal of
elements incorporated by the manufacturer, building in of additional components
into the water heater, replacement of elements by similar elements unapproved by
the manufacturer
•
These instructions shall also apply to water heaters equipped with a heat
exchanger.
•
If the power supply cord (of models that have one) is damaged, it must be
replaced by a service representative or a person with similar qualification, to
avoid any risk.
•
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 without
supervision.
IV. DESCRIPTION AND PRINCIPLE OF WORK
The appliance consists of a boiler shell, a flange at its lower
end /with vertically-installed boilers/ or lateral flange/with
horizontally-installed boilers/, protective plastic panel and non-
return safety valve.
1. The body consists of a steel reservoir (water tank) and
housing (outer shell) with thermal insulation placed in-between
made of ecologically clean high density polyurethane foam, and
two pipes with thread G (table 1 to fig. 1a; table 2 to fig. 1b) for
cold water supply (marked by a blue ring) and hot water outlet
pipe (marked by a red ring).
The inner tank may be of two types depending on the model:
•
Made of steel protected form corrosion by a special glass-
ceramics coating
•
Made of stainless steel
The vertical water heaters may be outfitted with a built in heat
exchange unit (boiler tube). The boiler tube's entrance and exit
are located at the sides and represent pipes with thread G ¾ ".

2. The flange is outfitted with: electric heater and thermostat.
The water heaters with glass-ceramics coating are outfitted with
a magnesium protector.
The electric heater is used for heating the water in the tank and is
managed by the thermostat, which automatically maintains the
set temperature.
The thermostat has a built in overheating safety device, which
switches of power to the heater when the water temperature
reaches excessive values.
3. The safety-return valve prevents the appliance's complete
emptying in the event the cold water supply is interrupted. The
valve protects the appliance from pressure increases higher than
the allowed value during heating (! pressure increases upon an
increase of temperature), via release of excess pressure during
the drainage opening
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.
