3. STARTING AND OPERATION

3.1. Commissioning

3.1.1. 

Shut off the hot water supply of the central water supply system. Before connect the appliance to power source, 

fill the tank up with mains water. To do this, turn on hot water mixer tap

and then tap of cold water supplied to the water heater.

3.1.2. 

Once the water heater is full, the water will flow from the mixer tap. Check the flange for leakages. Center it and tighten

the nuts if necessary.

3.1.3. 

Turn the hot water tap on the mixer off.

3.1.4. 

Connect the appliance to power source.

3.2. Temperature control

3.2.1.

 In models equipped with external control, water temperature can be controlled by a handle connected to the thermostat

in accordance with marks.

3.2.2. 

The temperature is set by using the regulation button clockwise to increase the temperature of heating and counterclockwise

to decrease it.

3.2.3. 

The indicator lamp is constantly lighting during heating phase, and turns off after reaching the set temperature.

3.2.4. 

If an appliance model does not have an external control, temperature can be set by turning the adjusting screw of the

thermostat in the range marked by «+» and «-» signs. To do so, disconnect the water heater from the power supply and remove

the plastic cover of the appliance.

3.2.5.

 It is recommended to install the controller in a position corresponding approximately to 75% of the maximal value. In

this case, the appliance is operated in economy mode significantly reducing the rate of scale formation.

4. MAINTENANCE AND REPAIR WORKS

Attention! Do not try to repair the appliance by yourself. All maintenance and repair works should be carried

out by a qualified technician in conformity with the safety norms and with any provisions set forth in this manual.
4.1. Water Drain

If there is a possibility that the ambient temperature drops below 0°C in the room where the appliance is installed, drain

water from the water heater.

4.1.1. 

Disconnect the appliance from the electrical supply;

4.1.2. 

Make sure that the water in the appliance is of safe temperature;

4.1.3. 

Turn off the tap of cold water supply to the water heater;

4.1.4. 

Turn on the hot water tap on mixer for pressure relief inside the tank;

4.1.5. 

Turn on the T-connector stop valve installed at hot water outlet (marked with red ring) for air access into the tank. If it is

absent, remove the connections at the water heater outlet;

4.1.6. 

Connect drain hose directed into the sewer to the T-connector stop valve installed at the cold water inlet of the water

heater (marked with the blue ring) and open it. If there is no T-connector, connect the hose to water heater inlet;

4.1.7. 

After draining, make sure there is no water inside the water heater.

Freezing of water inside the water heater leads to irreversible changes and defects.

It invalidates all warranty liability on the part of the manufacturer.
4.2. Replacing internal parts

Remove the cap to access the electrical parts.

To work on the thermostat (

T

 Fig. 3), first disconnect it from the power supply cable (

W

 Fig. 3), disconnect the cables

(

Y

 Fig. 3), loosen the screw (

K 

Fig. 3), remove the cable from its housing and remove the support (

S

 Fig. 3).

The product is equipped with dry heating elements (not in direct contact with the water) which, therefore, can be replaced without empty-

ing the appliance.

To intervene on the defective heating element, ascertained using a tester, disconnect the cables (

X

 Fig. 4) and loosen the spring (

M

 Fig. 4). 

Slide out the damaged heating element from its housing and replace it.

The magnesium anode (

N

 Fig. 6) must be replaced every two years, under penalty of warranty invalidation. In case of aggressive water or 

water that is rich in chlorides, it is advisable to check the condition of the anode every year. To replace it, first empty the appliance, loosen the 

5 bolts (

C

 Fig. 5), remove the flange (

F

 Fig. 5) and loosen the anode from the support bracket.

During reassembly, make sure that all components are put back in their original positions.

We recommend replacing the flange gasket every time when reassembling.

Prior to any repair or maintenance procedure, disconnect the unit from power source.

Use original spare parts of the manufacturer only.
4.3. Periodical maintenance

4.3.1. Magnesium anode

The magnesium anode rod is an integral part of the protection system of water tank and heating element against corrosion 

against corrosion.

It’s necessary to check the condition of the magnesium anode rod ANNUALLY.

In case of severe wear, the magnesium anode rod must be replaced.

The warranty for water tank and heating element with the worn with the worn magnesium anode rod (residual volume is less 

than 30%) is not valid.

The magnesium anode rod should be replaced at least once in 24 months (except for the water

heater with the internal tank made of stainless steel).

The magnesium anode rod is a consumable item that cannot be replaced underwarranty.
4.3.2. Safety valve

The safety valve (pressure safety device) must be inspected regularly to check that it is not blocked or damaged. Replace the 

valve or remove limescale deposits if necessary. If the safety valve is equipped with a lever, regular valve correct operation check 

procedure can be performed with its help.

Before cleaning, isolate the appliance from the mains by 
unplugging it or turning the switch off
