2.2. Hydraulic connection

Note! Installation of safety valve included in the delivery set is necessary.

Do not install any stop valve between the safety valve and the inlet of the tank and do not block the drain hole of the 

safety valve.

Demountable connectors should be used for the water heater connection to the water supply system.

recommended to turn the safety valve no more than 3−4 turns, providing sealing with water-proof sealing material.

3. STARTING AND OPERATION

3.1. Commissioning

3.1.1.

 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.

 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.

3.2.3. 

To do so, disconnect the water heater from the power supply and remove the plastic cover of the appliance.

3.2.4.

 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

Disconnect the water heater from the electricity supply. Remove the appliance cover. To replace the thermostat pull it straight 

out ot the cluster and disconnect from power supply.

Prior to work, the water heater must first be emptied. For models with an autoclave flange, remove the nut (

D 

in Fig. 3), remove 

the flange holder (

S

 in Fig. 3) and open the flange (

F

 in Fig. 3) by pressing it inside. Remove the flange by turning it on its axis.

For models with a flange on the 5 bolts, remove 5 nuts (

C

 in Fig. 4) and remove the flange (

F

 in Fig. 4). The heating element

and anode rod are attached to the flange. During reassembly, make sure that the heating element, flange gasket and the 

thermostat 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 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 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 under warranty.
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.
