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.
