EN

English

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 (

)

3.3. 

Models without power supply 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. Copper single core (rigid 

– non stranded) conductor shall be used for the connection 

– cable 3 x 1.5 mm2 for power 2000 W.
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.
In order to fix the power cable to the water heater, it is 

necessary to remove the plastic cover 

(fig.5)

. The power 

leads connections must be in accordance with the terminal 

markings of the thermal circuit breaker:

 •

the phase cable must be connected to the A1 (11) 

terminal 

 •

the neutral, to the B1 (21) terminal

 •

and the protection terminal, obligatory to the marked 

screwed joint 

. 

The power supply cord can be fixed to the plastic control 

panel with a cable stop. After the installation, the plastic 

cover must be replaced in its original position!

V. 

OPERATING THE DEVICE

Before initial start of the device, please make sure that the 

water heater has been correctly connected to the electrical 

network and that it is filled up with water.
Switching on the water heater is done through the device 

incorporated in the installation, which is described in sub-

item 3.2 of paragraph  V, or by inserting the plug into an 

electrical socket (for models with cord with a plug).

Operation modes:

1. 

Position (

) anti-freezing mode 

WARNING: The electrical power supply of the device 

should be switched on. The safety valve and the pipe 

connecting it to the device must be secured against freezing.

2. 

Position (

) maximum temperature

3. 

Position  (

) at this mode the water temperature 

reaches about 60°С. In this way heat losses are reduced.

4. 

Light indicator – at heating mode it is lit in red, and it 

is lit in blue when the water has been heated up and the 

thermostat has switched off.

5. 

Regulator knob – for temperature setting

Water heaters with electrical-mechanical POP-UP 

operation:

1. 

Push the knob to pop-up 

Fig. 7а

.

2. 

Set the temperature of the water heater 

Fig. 7b

This 

setting allows for gradual temperature adjustment.

3. 

Push the knob to retract 

Fig. 7c

 WARNING! Once a month set the knob to the 

position ‘maximum temperature’ for a period of 24 

hours (unless the device is constantly operated in this mode). 

Thus you will ensure better hygiene of the heated water.

VI. 

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. This is cost for the user.
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. 

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. 

Environmental protection instructions.

Old electric appliances contain prescious 

materials and must not be disposed with 

the domestic waste! Please make your 

active contribution to the protection of the 

environment and dispose of the appliance 

in the stations organized for the purpose (if 

available).
