Instructions for use and maintenance

EN

(rigid – non stranded) conductor shall be used for the connection – 

cable 3 x 2.5 mm² (cable 3 x 2.5 mm² 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 appliances remove the plastic 

cover. 

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!

that have one); R - heater; IL - light indicator; F - flange. 

VI. 

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

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.

2 – luminous indicators

3 - Handle for thermoregulator (integrated with the key of the power 

switch).

1.2. 

Switching on the appliance .

The appliance is switched on by means of the appliance 

incorporated in the installation described in subsection 3 of 

paragraph V or by connecting the plug to the electrical socket (if the 

model is with a cord with a plug).

The BOOST function is activated by the power switch button.
The power switch button of the appliance is embossed and is 

marked 



.

To  turn  on  the  BOOST  function,  press  the  button  until  it  stops  and 

then  release  it.  The  button  remains  pressed  and  it  illuminates  in 

red  color,  indicating  that  the  button  is  on  and  the  appliance  will  be 

working at maximum power.

The maximum heating power is marked on the appliance type 

plate.

The button illuminates continuously until the water in the appliance 

gets warm. The button goes out when the set water temperature is 

reached and the thermostat switches off the heater power.

To turn off the BOOST function, press the button until it stops, then 

release it. The button must be stand out and the light signalization 

goes out (if the appliance is in the heating mode), which means that 

the BOOST function is off. The appliance remains in the minimal 

power heater operation mode.

Attention

! The BOOST button illuminates only when the BOOST 

function and the water heating mode are active. When the BOOST 

function is activated and the set water temperature is reached, the BOOST 

button is not illuminating. Indication for active BOOST function is the 

pressed BOOST button.

BOOST

 “ON”

BOOST

 “OFF”

Control lights (indicators)

They illuminate in red color - the appliance is in the heating water 

mode. (If the appliance is in BOOST mode, the BOOST button 

illuminates in red color.)

They illuminate in blue color - the water in the appliance is heated 

and the thermostat switches off the heater‘s power. (If the appliance 

is in BOOST mode, the BOOST button extinguishes.)

Indicators do not illuminate in case of:

no electrical power is supplied to the appliance, or

the temperature protection of the appliance has been switched off - 

see section 2 below.

When the BOOST function is activated, the unit operates at 

maximum power to heat the water. The BOOST function is 

recommended when you want the appliance to reach the set water 

temperature for a short period of time.

Setting the temperature

This function allows you to select the desired temperature. To make 

your choice, turn the handle on the panel by placing the marker in 

the appropriate position (Fig. 2). To increase the temperature, turn 

clockwise.

Place the thermostat knob in position for maximum temperature 

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

month - see 

Annex-I (11)

 Maximum temperature of the thermostat. This 

ensures higher hygiene of the used hot water.

•

Anti-freeze mode

Set the handle to the „MIN“ position according to figure 2. With this 

setting, the appliance maintains a temperature that prevents the 

water from freezing.

 The power supply of the appliance must be switched on.  The 

safety valve and the pipeline from it to the appliance compulsory 

must be secured against frost.

•

Energy-save mode - Position

e

At this mode, water temperature reaches up to approximately 60°С. 

Heat losses are reduced in this way. 

2. 

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.

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).
