1.3 General boiler safe work instructions
General safety instructions
This device is not intended for use by persons with limited mental or psychophysical
capabilities, as well as by inexperienced persons including children. Children above 8
may handle this device only if an adult is present or if they are instructed for date
handling and are aware of all hazards.
Non-compliance with the safe work instructions may result in severe injuries, death,
material damage, and may jeopardize environment.
Before assembling the boiler professional inspection and control testing of the
electrical installation is required.
All works on the electrical installation should be performed by a competent and
authorized person in accordance with relevant regulations.
Commissioning, maintenance and repair may only be performed by an authorized
service technician.

4
Ensure technical approval of the installation in accordance with the relevant
regulations.
Danger due to compromising one’s own safety in case of need, e.g. in case of fire
Never put yourself in a life-threatening situation. Your safety should always come
first.
Damage due to errors in operating the boiler
Error in operating the device may cause bodily injuries or material damage.
Ensure that only persons who are able to use this boiler adequately have access to it.
Errors in operating the boiler may cause injuries and/or damage to the installations.
Assembly and commissioning of the boiler
Assembly of the boiler should be carried out only by authorized service technician.
The commissioning of the boiler should always be performed only if there is
appropriate pressure in the installation, while the working pressure must be in
accordance with the data of manufacturer. Do not close safety valves in any case, as
the material damage that may be caused by high pressure will thus be avoided.
The boiler should be installed only in a room in which water cannot freeze.
Do not use or store flammable materials (paper, thinner, paint, etc.) near the boiler.
Maintain safe separation distance from the boiler, in accordance with the regulations
in effect.
Life-threatening risk of electric shock
Electrical connection works should be done by authorized service technicians. Please
comply with the connection scheme.
Prior to works on electrical installations disconnect the power supply and ensure that
it may not be accidentally connected again.
The device must not be assembled in damp premises.
Maintained/check-up
We recommend that you sign a contract on inspection/maintenance with an expert
company, so that the inspection and necessary maintenance of the device may be
carried out once a year.
End-user of the boiler is responsible for ensuring that the hearing installation is safe
and environmentally friendly.
Adhere to the safe work instructions in the section
Spree parts
No liability shall be accepted for damage caused by use of spare parts which have not
been delivered by the manufacturer.
Use only original spare parts.
Damage to the system as a result of freezing temperatures
In case of freezing temperatures, protect the heating system from freezing. Heating
water should be drained at the lowest point of the heating system.
Instructions for service technicians
Inform the end-users about the manner of work and the maintenance of the boiler.
Warn the end-users that they must not make any change or repairs on their own.
Ensure that the children do not use this boiler without supervision and not play with it.

5
Hand over boiler technical documentation to the end-user.
Environmental protection/Disposal of waste
Dispose of packaging in an environmentally friendly manner.
Dispose of the boiler in an environmentally friendly manner at the recycling spot.
Cleaning of the boiler
Clean the boiler on the outside with a damp cloth.
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.

2.2 Electro-boiler models
It is important to emphasise that the boilers of 6kW and 9kW are produced in
two versions, with Single Phase and Three Phase connector. The boilers with Single Phase
connectors are EK 06 Smart MONO EU and EK 09 Smart MONO EU, boilers with Three
Phase connectors are EK 06 Smart EU and EK 09 Smart EU. When purchasing the product,
you should emphasise which connector you want. Subsequent “reconnections” are not
approved by the manufacturer.
2.3 Declaration of conformity
We declare that these boilers have been examined in accordance with the Directives 2006/95/EC
(Low Voltage Directive - LVD) and 2014/30/EU (Electromagnetic Compatibility Directive -
EMC).
