Instructions for use and maintenance
EN
•
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. КAlterations and modifications shall mean each instances
of removal of elements incorporated by the manufacturer, building in
additional components into the water heater, replacement of elements by
similar elements unapproved by the manufacturer.
•
If the supply cord (of models that have one) is damaged, it must
be replaced by a representative of the service or by an appropriately
qualified person, in order to avoid any risks
•
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 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 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.
