2. Information about the boiler
2.1 Description of the product
EK-SMART EU is produced with the following powers:
6kW, 9kW, 12kW, 16kW, 18kW, 21kW, 24kW, 27kW.
Advantages of electric boilers: reliable heating, quiet work, not requiring, a separate room for
installation, small dimensions, low price, high level of operational safety, absence of
chimney, no harmful emissions during operation (environmental protection). Smaller power
boilers of up to 9kW may require Single Phase or Three Phase power supply, while boilers of
greater power exclusively require Three Phase power supply.
In addition to standard elements of an electric boiler, the EK Smart EU electric boiler contains:
expansion vessel, circulation pump, safety valve, filling and drainage tap, automatic air vent,
etc.
The device is equipped with a protective assembly unit which guarantees complete safety.
Heating elements and pump valve are turned on through controller in charge of maximum work
optimisation.
Specially designed logarithm measures the time of work of each heating element and
periodically turns off the heating elements which worked the most and turns on those that
worked the least. In this way, equal exploitation of the heating elements is ensured, which
significantly extends the working life of the product.
Algorithm is designed upon the principle of modulation, so, as the boiler approaches the set
temperature, it reduces its power output and thus achieves maximum comfort with minimum
consumption.
Additional equipment: room thermostat is recommended since they significantly increase the
efficient energy use of the product and retain the same comfort with reduced consumption.
Electric boiler may be used:
1) As a principal source of heating (through radiators: in houses, holiday cottages,
apartments...)
2) As an auxiliary/additional source of heating (systems with a heat pump, solar systems,
pyrolytic boiler...)
3) For heating through heat accumulator (accumulation)
In addition to already mentioned inputs and outputs, EK-Smart EU boiler controller also
contains additional equipment and functions which provide maximum comfort and safety to
the end-user with minimum consumption.

9. Boiler commissioning
NOTE: First commissioning must be carried out by an expert – authorised service technician.
- Before commissioning, check the tightness of the hydraulic network. All the valves in the
network, including thermostat if any, must be in a position (open) which enables smooth water
circulation through the boiler and pipe network. The pressure in the system must be within the
limits prescribed by the Instruction.
- Check whether the device is properly connected to the electrical network. Check whether all
switches on the device and turned off (0), and the regulation thermostat is at the far-left position.
- Turn on the fuses in the distribution cabinet of the house electrical wiring.
- Turn on the automation system of the boiler by pressing ON/OFF button.
- If the room thermostat is connected to the boiler, it should also be turned on.
10. Cleaning and maintenance of boiler
WARNING: Material damage caused by unprofessional maintenance!
Insufficient or unprofessional maintenance of the boiler may result in
damage or destruction of the boiler, as well as in the loss of guarantee.
Ensure regular, comprehensive and professional maintenance of the
heating installation.
Protect electrical components and working units from water damp.
- Use only original spare parts of the manufacturer or those approved by the manufacturer.
For damages resulting from the use of spare parts not delivered by the manufacturer, the
manufacturer does not hold any liability.
Cleaning the boiler
- The boiler should be cleaned on the outside using a wet cloth.
The quantity of newly filled water is reduced in the first days after filling, as a result of
heating. It, thus, creates airbags which obstruct the work of the heating installation.
Testing the working pressure
-Working pressure of the new heating installation should be checked daily at the beginning.
In case of need, fill up the heating installation with water and purge it.
- Later, working pressure should be checked once a month. In case of need, fill up the heating
installation with water and purge it.
- Test the working pressure. If the pressure drops under 1bar, fill up the installation with
water.
- Purge the heating installation.
- Check the working pressure again.
Fill up with water and purge the installation
WARNING: Material damage caused by temperature strain. If the
heating installation is filled in a warm state with cold water, it may result
in cracks.
Heating installation should be filled only in cold state (temperature
of the flow is maximum 40°C).
28
SRB
WARNING: Material damage caused by frequent filling up of water!
Due to frequent filling up of the heating installation with water,
depending on the water characteristics the installation may be
damaged by corrosion or lime scale.
Tightness of the heating installation and functional operation of the
expansion vessel should be tested.
- Connect the hose to the filling and drainage tap.
- Fill the hose with water and set the connection of the hose of the filling and drainage
tap.
- Tighten the hose with a hose clamp and open the filling and drainage tap.
- Slowly fill the heating installation. At the same time, monitor the pressure value on
manometer.
- During the filling, purge the system.
- When the working pressure has been reached, close the filling and drainage tap.
- When the pressure value has been reduced by purging, the water must be filled up.
- Remove the hose from the filling and drainage tap.
11. Operating problems and solutions
1. Boiler is working, but the temperature is unsatisfactory?
- Boiler power is insufficient => Increase the power by selecting another group of heating
elements.
- Selected temperature is insufficient => Increase the temperature on the regulation
thermostat.
- There is excess air in the system => Purge the whole system.
- One of the heating elements is faulty => Call the repair service in order to do the
replacement.
- The boiler does not have all three phases => Call a professional to check.
2. Heating is not functioning and the boiler shows a certain temperature?
- A valve or coil in the system is closed and the flow disabled => Check the valves and open
them if necessary.
- Ball valve on voltage/return line is closed => you must open the valves.
- Pump is not working or is blocked for some reason=> Call a professional for repair.
