WARNINGS
The appliance may be used by children older than 8 years old, elderly persons
and persons with physical, sensory or mental disabilities or lacking
experience and knowledge, if they are under supervision or taught about safe
use of the appliance and if they are aware of the potential dangers.
Children should not play with the appliance.
Children should not clean or perform maintenance on the appliance without
supervision.
Installation should be carried out in accordance with the valid regulations
and according to the instructions of the manufacturer and by qualified staff.
In a closed, pressurised system of installation, it is obligatory to install a
safety valve on the inlet pipe with a rated pressure of 0.6 MPa (6 bar), 0.9
MPa (9 bar) or 1.0 MPa (10 bar) (see the label), which prevents the elevation
of pressure in the boiler by more than 0.1 MPa (1 bar) above the rated
pressure.
Water may drip from the outlet opening of the safety valve, so the outlet
opening should be set to atmospheric pressure.
The outlet of the safety valve should be installed facing downwards and in a
nonfreezing area.
To ensure proper functioning of the safety valve, the user should perform
regular controls to remove limescale and make sure the safety valve is not
blocked.
Do not install a stop valve between the water heater and the safety valve,
because it will impair the pressure protection of the heater!
Before connecting it to the power supply, the water heater must be filled with
water!
The heater is equipped with an additional thermal cut-off for protection in
case of failure of the operating thermostat. In this case, however, the
temperature of the water in the heater can reach up to 130 °C according to the
safety standards. During the water supply installation, the possibility of
temperature overloads should be taken into account.
If the heater is to be disconnected from the power supply, please drain any
water from the heater to prevent freezing.
Water can be drained from the heater through the boiler inlet pipe. For this
purpose it is advisable to install a T- element with an outlet valve between
the inlet pipe and safety valve.
Please do not try to fix any defects of the water heater on your own. Call the
nearest authorised service provider.
Our products incorporate components that are both environmentally safe and
harmless to health, so they can be disassembled as easily as possible and
recycled once they reach their final life stage.
Recycling of materials reduces the quantity of waste and the need for
production of raw materials (e.g. metals) which requires a substantial amount
of energy and causes release of harmful substances. Recycling procedures
reduce the consumption of natural resources, as the waste parts made of
plastic and metal can be returned to various production processes.
For more information on waste disposal, please visit your waste collection
centre or the store where the product was purchased.
Dear buyer, thank you for purchasing our product.
PRIOR TO THE INSTALLATION AND FIRST USE OF THE ELECTRIC WATER HEATER, PLEASE
READ THESE INSTRUCTIONS CAREFULLY.
This water heater has been manufactured in compliance with the relevant
standards and tested by the relevant authorities as indicated by the Safety
Certificate and the Electromagnetic Compatibility Certificate. Its technical
characteristics are indicated on the label on the bottom of the heater next to
the pipes. The installation must be carried out by qualified staff. All
repairs and maintenance work within the water heater, e.g. lime removal or
inspection/replacement of the protective anticorrosion anode, must be carried
out by an authorised maintenance service provider.
INSTALLATION
The water heater shall be installed as close as possible to the outlets. When
installing the water heater in a room with a bathtub or shower, take into
account the requirements defined in IEC Standard 60364-7-701 (VDE 0100, Part
701). It has to be fitted to the wall using appropriate wall screws with a
minimum diameter of 8 mm. A wall with a poor loadbearing capacity must be
properly reinforced where the heater will be installed. The water heater may
only be fixed upon the wall vertically. To facilitate future service
interventions, you are advised to install the heater in accordance with the
installation measurements (see Fig. 1).

CONNECTION TO THE WATER SUPPLY
The water heater connections for the inlet and outlet of water are colour-
coded. The inlet of cold water is marked with blue colour, while the hot water
outlet is marked with red colour.
The water heater can be connected to the water supply in two ways. The closed-
circuit pressure system enables several points of use, while the open-circuit
gravity system enables a single point of use only. The mixer taps must also be
installed in accordance with the selected installation mode.
In a closed, pressurized system (Fig. 2) pressurized mix taps should be used
at the outlet points. To ensure safe operation of the heater a safety valve
should be installed on the inlet pipe to prevent elevation of pressure for
more than 0.1 MPa (1 bar) above the nominal pressure. The outlet opening on
the safety valve must be equipped with an outlet for atmospheric pressure. The
heating of water in the heater causes the pressure in the tank to increase to
the level set by the safety valve. As the water cannot return to the water
supply system, this can result in dripping from the outlet of the safety
valve. The drip can be piped to the drain by installing a catching unit just
below the safety valve. The drain installed below the safety valve outlet must
be piped down vertically and placed in an environment that is free from the
onset of freezing conditions. To avoid water dripping from the safety valve,
an expansion tank should be installed on the inlet pipe of the heater with the
capacity of at least 5 % of the heater volume.
To ensure proper operation of the safety valve, periodical inspections must be
carried out to remove limescale and make sure the safety valve is not blocked.
To check the valve, open the outlet of the safety valve by turning the handle
or unscrewing the nut of the valve (depending on the type of the valve). The
valve is operating properly if the water comes out of the nozzle when the
outlet is open.
An open-circuit, non-pressurized system (Fig. 3) requires the installation of
a non-return valve at the water inlet to prevent water draining out from the
tank in the event of the water supply running dry. This installation mode
requires the use of an instantaneous mixing tap. As the heating of water
expands its volume, this causes the tap to drip. The dripping cannot be
stopped by tightening it further; on the contrary, the tightening can only
damage the tap.
No closing valve may be built-in between the water heater and return safety
valve, because with it the pressure protection would be impeded!
The heater can be connected to the domestic water supply network without a
pressure reducing valve if the pressure in the network is lower than the
nominal pressure. If the pressure in the network exceeds the nominal pressure,
a pressure-reducing valve must be installed.

Before connecting it to the power supply, the water heater must be filled with
water.
When filling the heater for the first time, the tap for the hot water on the
mixing tap must be opened. When the heater is filled with water, the water
starts to run through the outlet pipe of the mixing tap.
The GBK combined water heater has an additional tubular heat exchanger for
heating domestic water using other energy sources (e.g. central heating, solar
collector, heat pump).
The heating system using an electric heater and the system using the heat
exchanger can work simultaneously or individually. The combined water heater
is connected to the water pipeline and to an additional energy source. The
inlet of the heating medium into the heat exchanger is labelled with red paint
while the outlet is labelled with blue paint.
WARNING: When the temperature of the additional heat source drops and
circulation of water through the exchanger is enabled, uncontrolled reduction
of heat can occur in the water heater. When connecting the appliance to other
heat sources, the temperature regulation of the additional source must be
carried out properly.
The GBK heater can also be connected to the hot water circulation line. The
hot water circulation line allows warm water to always be available everywhere
at once. Connect the eturn line of hot water to the connection on top of the
heater. Before connecting, please remove the plastic cap and unscrew the
sealing plug on top of the heater.
WARNING: The hot water return line must be installed before filling the
heater with water. The use of circulation line results in additional heat
losses in the water heater.
CONNECTING THE WATER HEATER TO THE POWER SUPPLY NETWORK
Before connecting to the power supply network, install a power supply cord in
the water heater, with a min. diameter of 1.5 mm2 (H05VV-F 3G 1.5 mm2 ). To do
this, the protective plate must be removed from the water heater.
In the electrical installation, please install a disconnect switch to separate
all poles from the power supply network in accordance with the national
regulations.

CAUTION: Before any intervention into the interior of the water heater, disconnect it from the power supply network! This intervention may only be performed by a trained professional!
USE OF THE HEATER
After it has been connected to the water and power supply grid, the heater is
ready to be used. When connected to the power supply, the heater runs in
standby mode. In the standby mode, the heater maintains the water temperature
of 10 °C.
The figure below shows one of the models of the electronic regulator. As the
heaters may come with various types of equipment, this manual may describe
functions and equipment that are not part of your heater.

The heater equipped with the “Eco Base” electronic regulator enables the
setting of water temperature, display of water temperature and error
diagnostics.
In addition to the “Eco Base” function, a heater with the “EcoSmart” also
enables the smart mode of the heater, which reduces the consumption of
electrical energy.
Switching the heater on/off
The water heater can be switched on by holding the 2 button for about 3
seconds. By holding the 2 button for about 3 seconds again, the heater goes
into standby.
Operating the heater – manual setting
Temperature is set by pressing button 2 until you get the desired temperature
level (preset temperature level is 57 °C):
| – Freeze protection, temperature about 10 °C
---|---
| – Water temperature about 35 °C.
| – Water temperature about 57 °C.
| – Water temperature about 75 °C.
Once the maximum level “ ” is achieved, pressing the 2 button returns the
temperature to the first setting ” “.We recommend the ” ” setting. This
setting is the most energy efficient. The temperature of water is about 57 °C,
while limescale production and heat loss will be smaller than in case of
higher temperature settings. The functioning of the electrical heater is
indicated by a red control light 3 (only in
the “Exobases” models) which stays on until the water in the heater reaches
the set temperature or until the heater is switched off. The temperature of
water in the heater is indicated on the display 1 .
If the heater will not be used for a longer period of time, please protect its
contents from freezing by setting the temperature to the ” ” position. At this
setting, the heater will maintain the temperature of water at about 10 °C.
Functioning of the heater in the “EcoSmart” mode (only in the “EcoSmart”
models)
This mode is appropriate especially if you have well-established hot water
consumption habits (e.g. showering every day at approximately the same time).
To start the heater in the “EcoSmart” mode, you first have to start recording.
During the recording time, the electronic regulator remembers your habits and
takes them into account while heating the water after the recording period has
ended. The recording takes place for 7 days. The “EcoSmart” mode reduces the
consumption of electrical energy.
- Pressing button no. 4 will begin the recording of your habits. The green control light 3 will flash during the recording period. Once recording concludes after 7 days, the recording regime will begin running automatically. The green control light 3 will light up when the heater is functioning in the “EcoSmart” mode.
- By pressing 4 again, you can switch off the recording or the “EcoSmart” function. The heater resumes to the basic mode of operation. The water is heated to the set temperature.
- The “EcoSmart” function can be resumed by pressing button no. 4 . If the regime has already been recorded (if the recording was not interrupted), the regime will begin running and the green control light 3 will light up. If the recording was interrupted, a new 7-day recording period will begin and the green control light 3 will again begin flashing.
- If the electronic regulator has recorded the regime but the user’s hot water consumption habits have changed, a new recording period must be started. It can be started by holding button no. 4 . The recording period lasts 7 days.
The Anti-Legionella Function
If the water in the heater does not reach 65 °C for 14 consecutive days, the
anti-legionella function heats the water to 70 °C and maintains this
temperature for 120 minutes.
Indication of errors
In case of error, control lights start to flash on the display 1 .

E44| • Dry start| • Repeated 4x quick pulse of the control light on the
display 1 .| • Fill the heater with water.
• The error is deleted by switching off the heater or by holding button 2 for
3 seconds.
Emptying the heater
If you are planning to unplug the heater from power supply, please drain out
all the water to prevent freezing. Water can be drained from the heater
through the boiler inlet pipe. For this purpose it is advisable to install a
T- element with 0an outlet valve between the inlet pipe and safety valve.
Before draining, please unplug the heater from the power supply, open the warm
water handle on the mixing tap and drain the warm water. When the water in the
heater is cooled, close the flow of cold water into the heater and unscrew the
flexible pipe on the warm water outlet. The heater can now be drained through
the outlet valve on the inlet pipe. After draining the water through the inlet
pipe, a small quantity of water remains in the heater. When refilling the
heater with water it is recommended to open the warm water tap on the mixing
tap and let the water run for at least two minutes through the outlet pipe
(the water stream should be steady, medium strength, about as thick as a
pencil).
MAINTENANCE
Clean the exterior of the heater using a soft cloth and mild detergent
intended for cleaning smooth varnished surfaces. Do not use detergents that
contain alcohol or abrasives.
With regular service inspections you will ensure faultless functioning and
long life of the heater. Tank corrosion warranty applies only if all the
prescribed regular inspections of the protective anode wear have been made.
The period between regular inspections should not be longer than stated in the
warranty certificate. Inspections should be carried out by authorised service
providers that will record each inspection on the warranty statement of the
product. Upon inspection the service provider will inspect the amount of wear
on the anti-corrosion anode and, if necessary, clean the limescale that
accumulates depending on the quality, quantity and temperature of the water
inside the heater. The service provider will also recommend the date for the
next inspection depending on the condition of the heater.
Please do not attempt to fix any defects of the heater by yourself. Call the
nearest authorised service company.
