Water heaters  fitted with a supply cord without a plug.  

The appliance has to be connected to a separate electricity circuit of the 

stationary electrical wiring.The connecting has to be constant- with no plug 

contacts. The circuit has to be supplied with a safety fuse (16A) and with 

inbuilt device to ensure disconnection of all pole pieces in the conditions of 

over-voltage from category III. 

The connecting of the conductors of the supply cord of the appliance has to 

be carried out as follows:

•

conductor with brown insulation – to the phase conductor of the 

electrical wiring (L)

•

conductor with blue insulation- to the neutral conductor of the wiring (N)

•

conductor with yellow-green insulation – to the safety conductor of the 

wiring (

)

3.2. 

Models without power cord

The appliance has to be connected to a separate electricity circuit of the 

stationary electrical wiring. The circuit has to be supplied with a safety fuse 

16A (20A for power > 3700W). Copper single core (rigid – non stranded) 

conductor shall be used for the connection – cable 3 x 2.5mm² (cable 3 x 

2.5mm² for power > 3700W).

The electrical circuit supplying the appliance must have an in-built device 

ensuring the splitting of all terminal poles under conditions of super-voltage 

of category III.

To install the power supply wire to the boiler, remove the plastic cover 

(Fig.2). 

Connect the power wires in compliance with the marks on the terminals, as 

follows:

•

the phase - to mark A, A1, L or L1;

•

the neutral - to N (B or B1 or N1)

•

The safety wire must be obligatory connected to the screw joint marked 

with 

 . 

After the installation, put the plastic cover back in its place!

RUST PROTECTION MAGNESIUM ANODE 

(FOR WATER 

HEATERS WITH WATER TANKS COVERED BY GLASS-CERAMICS 

COATING)

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!

VII. 

OPERATION.

1. 

Switch on.

Before switching on the appliance for first time, make sure that the boiler 

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

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

described in item 3.2 of Section V, or upon connecting the plug to the 

electrical contact (in the case of an extension cable with plug).

2 - Light indicator 

3 - Regulator handle (only for models with adjustable thermostat)

When there is in-built in switch in the water heater, you must switch 

it on. 

Electrical switch with one knob: 

0 – switched off;  

I – switched on; 

The knob lit when the switch is on. 

The control lamp on the panel indicates the state (the mode) in which the 

appliance is placed: it is lit when the water is being heated and is switched 

off when the specified by the thermostat water temperature level is reached.

The buttons of the switch lit on, if they are switched on and during heating. 

They stops to lit when the preset temperature of the water is reached and 

the thermostat switch-off the voltage supply.

The control lamp lit on when there is supply voltage from electrical main. 

It does not lit on when there is not supply voltage or the thermal cut-out 

(temperature protection) is switched off (see 3 below).

•

Temperature setup (for models with adjustable thermostat).

This setup allows the gradual setting of the desired temperature, achieved by using a 

handle on the control panel.

Position 

e

 (Energy-save mode) – At this mode, water temperature reaches 

up to approximately 60°С. Heat losses are reduced in this way.

Fig. 2a indicates the direction of rotation of the knob for the other models 

with externally adjustable thermostat. 

Attention! Place the thermostat knob in position for maximum 

temperature (unless it is on this position constantly), for period of one 

day each month. This ensures higher hygiene of the used hot water.

3. 

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. 

Attention! When this device operates, it does not self-reset and the 

appliance will not work. Please call an authorized service for solving 

the problem.

VIII. 

MODELS EQUIPPED WITH A HEAT EXCHANGER (SERPENTINE TUBE).

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. 1е.

Technical parameters (

table 6)

:

Surface of serpentine [m²] - S;

Volume of serpentine [l] - V;

Operational pressure of serpentine  [MPa] - P;

Maximum temperature of heat carrier [°C] - Tmax.

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.

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.

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.

IX. 

PERIODIC MAINTENANCE

In the conditions of normal use of the water heater, under the influence of high 

temperature, limestone (the so-called lime scale) deposits on the surface of the 

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

and the water. The temperature on the surface of the heating element and around 

it increases. Specific noise can be heard – 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 centre or service facility, this service remaining at the customer’s expense. 

This preventive maintenance should include cleaning and examination of the 

anode protector (for water heaters with glass-ceramic coating), which has to be 

replaced with a new one, if necessary.

To clean the appliance, use a damp cloth. Do not use abrasive or solvent-

containing detergents.

The manufacturer does not bear responsibility for any consequences 

arising from non-adherence to these instructions.

Instructions for protection of the environment
