RUST PROTECTION MAGNESIUM ANODE

The magnesium anode protects the water tank’s inner surface from corrosion.

The anode element is an element undergoing wear and tear and is subject to 

periodic replacement.

In view of the long-term and accident free use of your water heater, the 

manufacturer recommends periodic inspections of the magnesium anode’s 

condition by a qualified technician and replacement whenever required, and this 

could be performed during the appliance’s technical preventive maintenance. 

For replacements, please contact the authorized service stations!

VI. 

OPERATION

1. 

Switch on:

Before switching on the appliance for first time, make sure that the water heater is 

properly connected to the power supply network and full with water.

The appliance is switched on by a switch integrated into the installation, described 

in item 3.3 of Section IV, or upon connecting the plug to the electrical contact (in 

the case of an extension cable with plug).

Water heaters with electromechanical control

2 - Power switch   

3 - Indicator lights  

Thermal regulator (1) and indicator light for „heating up / ready to use“ 

Setting of the temperature is provided by a knob for the thermal regulator (1). This setting 

allows for gradual adjustment to the desired temperature.
Fig.2 displays the rotation direction of the knobs.
e  ENERGY SAVING – in this mode the water in the appliance is at a temperature of 

approximately 60°С. Thus thermal loss is reduced.
Indicator light “heating up / ready to use“ 

 - indicates the status/operation mode of the 

appliance: the light is red while the water is heated and it is blue when the water has reached 

the temperature as set by the thermostat. The light is off when the power switch is in off 

position.

Power switch (2) and indicator lights 

Single-level power switch:

Protection according to the temperature (valid for all models)

The appliance is equipped with a special facility (thermal circuit-breaker) for protection 

against over-heating of the water, which is switching off the heater from the electricity 

network, when the temperature reaches too high values.

When this device operates, it does not self-reset and the appliance will not 

work. Please call an authorized service for solving the problem.

VII. 

MODELS EQUIPPED WITH A HEAT EXCHANGER (SERPENTINE TUBE) - FIG.1C, 

FIG.1D, FIG.1E AND TABLES 

3 ÷ 5

These are appliances with inbuilt heat exchanger and are intended to be connected to the 

heating system with maximum temperature of the heat carrier of 80°C. The control over 

the flow through the heat exchanger is a matter of solution for the particular installation, 

whereby the choice should be made at its design (e.g. external thermostat that measures the 

temperature in the water tank and operates a circulation pump or a magnet valve). 
Water heaters with a heat exchanger provide the opportunity for the water to be heated in 

two ways:

1. 

by means of a heat exchanger (coil) – a primary way of heating the water, 

2. 

by means of an auxiliary electrical heating element with automatic operation, built in 

the appliance – it is used only when additional heating of the water is needed or in case 

of repairs to the system of the heat exchanger (coil). The proper way of connecting the 

appliance to the electric network and how to work with it has been specified in the previous 

paragraphs.

Mounting

In addition to the mounting manner outlined above, especially for the latter models, it shall 

be required to connect the heat exchanger to the heating installation. The connections are 

to be carried out in observance of the direction indicated by the arrows on Fig. 1c, 1d, 1e. We 

recommend you mount stopcocks at the heat exchanger’s entry and exit points. By stopping 

the flow of the thermophore via the lower (stopcock) you shall avoid the unnecessary 

circulation of the thermophore during periods of use only of the electric heating element. 
Upon disassembly of you water heater equipped with a heat exchanger you must close both 

stopcocks.

The usage of dielectric bushings for connecting the heat exchanger to an 

installation of copper pipes is obligatory.

For ensuring minimal corrosion, pipes with a limited diffusion of gasses must 

be used in the installation. 

Models with a single heat exchanger and a thermal sensor pocket

Appliance installation is responsibility of the customer hence a qualified 

installation technician has to perform it in accordance with the main user 

guide and the present appendix thereto.

For models with a possibility for installation of the thermal sensor pocket, delivered along 

with the appliance, it has to be installed where the „TS“ lead-in is. The thread needs to be 

tightened.

Models with two heat exchangers and a thermal sensor pocket 

These models allow for connection to two external heat sources – a solar panel and local 

or central water heating supply.  
Serpentine markings:

 •

S1 and an arrow pointing at the serpentine lead-in  – inlet of serpentine S1

 •

S1 and an arrow pointing outwards from the serpentine lead-in  – outlet of serpentine S1

 •

S2 and an arrow pointing at the serpentine lead – inlet of serpentine S2

 •

S2 and an arrow pointing outwards from the serpentine lead-in  – outlet of serpentine S2

There is a connexion with internal thread of ½” welded to the water tank for the purposes 

of installing thermal probe – marked with ‘TS”. The appliance is fitted with brass pocket for a 

thermal probe which should be screwed into the aforesaid connexion.

VIII. 

PERIODIC MAINTENANCE

Under normal use of the heater, under the influence of high temperature, lime 

scale /the so-called lime scale layer/ is deposited upon the heating element’s 

surface. This worsens the heat exchange between the heating element and 

water. The heating element’s surface temperature increases along /of boiling 

water/. The thermoregulator begins to switch on and off more frequently. A 

‘’deceptive” activation of the thermal protection is possible. Due to these facts, 

the manufacturer recommends preventive maintenance of your water heater 

every two years by an authorized service center or service base. This protective 

maintenance must include cleaning and inspection of the anode protector (for 

water heaters with glass-ceramic coating), which shall be replace with a new one if 

need arises. 

In order to clean the appliances use a damp cloth. Do not clean with abrasive or 

solvent content detergents. Do not pour water over the appliance.

The manufacturer does not bare the responsibility for all consequences 

caused by not obeying the instructions, given hereby.

Instructions for protecting the environment

Old electric appliances contain precious materials and thus should 

not be thrown together with the household litter. We kindly ask you 

make your active contribution for protecting the resources and the 

environment by handing over the appliance in the authorized buy-

back stations (if such exist).
