boiler.

In case that the pressure in the water mains is over the value 

pointed out in the above paragraph I, then it is necessary to 

assemble a pressure reduce valve, otherwise the water heater 

would not function properly. The Manufacturer does not assume any 

liability for problems arising out of the appliance’s improper use.

3. 

Water heater's electrical connection 

(fig.3)

 ATTENTION! Before you switch the power supply, make sure the 

appliance is full of water.

3.1. 

Models fit with power supply cord combined with a 

plug

 shall be plugged in a socket. The boiler can be disconnected 

from the power supply by unplugging.

 ATTENTION! The wall-plug must be properly connected to a separate 

electrical circle that is provided with a protector. It must be earthed.

3.2. 

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) (20A for power > 3700W) 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 ( )

3.3. 

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 mm

2 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. 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 (L) terminal 

•

the neutral, to the (N) 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 3.3 of 

paragraph  IV, or by inserting the plug into an electrical socket (for 

models with cord with a plug).
Clarification to 

Fig.5

:

1 - Light indicator 
2 - Regulator handle

Lamp (1) is on when the boiler is switched on in water heating 

mode. Lamp (1) switches off when the water reaches the preset 

temperature and indicates that the appliance is not in operation.

Temperature setup

This setup allows the gradual setting of the desired temperature, 

achieved by using a handle on the control panel.

Protection according to the temperature

.

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.

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.

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.

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).
