1PRODUCT TECHNICAL SPECIFICATION
1.1 FUNCTION DESCRIPTION
The heater is designed for the so-called accumulation heating of service water by electric energy, or by
thermal energy through exchanger. Water is heated by an electric element or heat exchanger in an
enamelled thermally insulated tank at the time specified by the electricity supplier. At the time of the
heating, the element is controlled by thermostat on which the desired temperature can be set (ranging
from 5 and 74℃).Once the selected temperature is reached, heating interrupts automatically. Water
accumulated in the tank is then used for consumption. The tank keeps constant pressure of water from the
water main. If the combination faucet hot water valve is opened, water from the water supply conduit
pressed out by cold water pressure flows out of the heater. Hot water flows out through the top part, and
water flowing in remains in the bottom part of the heater. Pressure principle allows hot water withdrawal
at any place from the heater (Fig. 6).
1.2 ADVICE FOR CUSTOMERS
1.2.1 HOT WATER CONSUMPTION
Consumption of hot water in households depends on the number of people, amount of
sanitary equipment, length, diameter and insulation of piping in the flat, or on individual
habits of users. The cheapest option of water heating comes at the time when the
electricity rate is reduced.
Find out in what time intervals your electricity supplier provides reduced tariff and,
depending on that information, select relevant volume and power input of the heater so that
your hot water consumption covered the needs of your household.
1.2.2 ENERGY SAVING
Hot utility water reservoir is insulated by means of top-quality polyurethane foam with zero
CFCs content. Adjust the temperature of the heater's thermostat to that level only that you
need to run your home. Thus you will reduce electricity consumption, as well as the amount
of lime sediments on the walls of the receptacle and on the heat exchanger.

- 5 -
EMERGENCY POWER CONSUMPTION
If no heated water is taken from the tank, a small amount of heat leaks. This loss is
measured for a period of 24 hours at the temperature of 65°C in the heater, and at 20°C in
its ambient area. The resulting value is expressed in units [kWh/24h] and indicates the
amount of power needed to maintain the set temperature.

1.3 DESIGN AND GENERAL HEATER DIMENSIONS
The heater tank is made of a steel plate and tested by 0.9 MPa overpressure. The inside of the tank is
enamelled. A flange is welded onto the bottom of the tank with a flange lid screwed to it.
A sealing ring is inserted between the flange lid and the flange. Thermowells for placing a heating element
and sensors of regulation thermostat and safety fuse are located in the flange lid. An anode rod is mounted
onto the M8 nut. The water reservoir is insulated by means of polyurethane foam. Electric wiring is placed
underneath the plastic removable cover. The temperature of water can be set using the thermostat. In
combined versions, a heat exchanger is welded in the pressure tank. The heat exchanger is only intended
for the heating circuit.

2OPERATION AND FITTING INSTRUCTIONS
2.1 OPERATING CONDITIONS
The tank shall only be used in accordance with the conditions specified on the performance
plate and in instructions for electric wiring. Besides legally acknowledged national
regulations and standards, also conditions for connection defined in local electric and water
works have to be adhered to, as well as the installation and operation manual. The room, in
which the appliance will be operated, must be frost-free. The temperature in the heater
installation location must not exceed +2 °C. The appliance has to be mounted at a
convenient place; it means that the appliance must be easily accessible for potential
necessary maintenance, repair or replacement, as the case may be.
We would like to emphasise that the heater must not be connected to power supply if
work involving flammable liquids (petrol, spot remover) or gases, etc., is performed
nearby.
If water is strongly calcareous we recommend that any of the common decalcifying device
was installed with the appliance, or the thermostat to be set to the minimum operation
temperature of 60oC. For proper operation, drinkable water of adequate quality shall be
used. To avoid potential sediments we recommend that the device was installed together
with a water filter.
2.2 WALL MOUNTING
Prior to mounting, check the loading capacity of the wall and, depending on the type of
masonry, choose a suitable anchorage material, or reinforce the wall, if needed. The water
heater shall only be mounted in vertical position so that the lower edge of the heater was
placed at least 600 mm above the floor (Figure 1). In combined heaters, elbows have to be
attached to the heating water inlet and outlet and, by turning them, the mounting either
from the right or from the left has to be determined (Figure 4). With regard to various types
of carrying masonry and broad assortment of special anchorage material available at the
market, we do not provide heaters with this material. The anchorage system has to be
selected individually, depending on the conditions. We recommend an authorised company
perform mounting on the wall and anchorage, or discuss the anchorage with a professional.

- 10 -
Figure 2
2.3 PLUMBING FIXTURE
Heaters are connected to plumbing fixtures as shown in (Figure 3, Figure 6).
For potential disconnection of the heater, the service water inlets and outlets must be
provided with screw coupling Js 3/4“. The safety valve is mounted on the cold water inlet
identified with a blue ring.
Each hot service water pressure heater must have a safety valve with a membrane spring.
The safety valve must be easily accessible, as close to the heater as possible. The inlet pipes
must have at least the same clearance as the safety valve. Safety valve is placed high enough
to secure dripping water drain by gravity. We recommend mounting the safety valve onto a
branch pipe. This allows easier exchange without having to drain the water from the heater.
Safety valves with fixed pressure settings from the manufacturer are used for the assembly.
Starting pressure of a safety valve must be identical to the maximum allowed heater
pressure, and at least 20 % higher than the maximum pressure in the water main. If the
water main pressure exceeds such value, a reduction valve must be added to the system. No
stop valves can be put between the heater and the safety valve. During assembly, follow the
guide provided by the safety equipment manufacturer.

- 11 -
It is necessary to check the safety valve each time before putting it into operation. It is
checked by manual moving of the membrane from the seat, turning the make-and-break
device button always in the direction of the arrow. After being turned, the button must click
back into a notch. Proper function of the make-and-break device results in water draining
through the safety valve outlet pipe. In common operation, such a check needs to be
implemented at least once a month, and after each heater shutdown for more than 5 days.
Water may be dripping off the drain pipe of the safety valve; the pipe must be open into the
air, pointed down; environment temperatures must not drop below zero. When draining the
heater, use the recommended drain valve. First, close the water supply into the heater. Find
necessary pressure values in the following table. For proper safety valve operation, a
backflow valve must be mounted on the inlet pipes, preventing spontaneous heater draining
and hot water penetrating back into the water main.
Required pressures – Table 4. We recommend that the hot water distribution from the tank was as short as
possible to minimise heat losses.
Table 4
Water heaters must be provided with a discharge valve mounted on the cold service water inlet to the
heater for potential disassembly or repair.

2.4 ELECTRICAL INSTALLATION
2.4.1 GENERAL INFORMATION FOR ELECTRICAL INSTALLATION
Perform the connection according to the scheme. Factory connection must not be changed! (Obrázek 5). In
the electric wiring casing remove the partition corresponding with the input wire diameter of φ8 or φ10
(Figure 4).The degree of protection of electric parts of the heater is IP 44. Power input of electric element is
2000 W.
Figure 4
It is necessary to observe the below requirements during the electric wiring.
•The wiring diagram is attached to the heater on the side of the electric installation
guard (see Fig. 5).
•Connection, repairs, and wiring inspections may only be implemented by a company
(person) authorised to such activity.
•Expert connection must be confirmed on the warranty certificate.
•The heater is connected to the 230 V/50 Hz electrical network using a fixed moving
conductor with a switch that turns off all network poles and the circuit breaker
(protector).
•Installations in bathrooms, laundry rooms, rest rooms and showers, must be in
compliance with standard.
•The degree of protection of electric parts of the heater is IP 44.
•Adhere to the protection against electric shock injury according to standard.
Figure 5

- 13 -
2.5 CONNECTION OF INDIRECT HEATER TO HOT WATER SYSTEM
a) Water heating by electric energy
After the heater is connected to electric network, the heating element starts heating water. The element is
turned on and off by a thermostat. After reaching the temperature set, the thermostat switches off the
electric circuit and thus discontinues water heating. The control light signals if the element is in operation
(light is on) or if it is off (the light goes out). In case of longer operation without using the heated volume,
the thermostat has to be set to position 5°C to 8°C (set the “snowflake” symbol on the thermostat selector)
to avoid its freezing, or electricity supply to the heater has to be switched off. In combined versions, the
stop valve on the inlet to the exchanger has to be closed at the inlet to the heat exchanger which prevents
heating the water in the hot water heating system.
b) Service water heating via thermal energy through heat exchanger
Closing valves of the heat exchanger must be opened which ensures heating water flow from the hot water
heating system. Together with THE closing valve, it is recommended to install an air outlet valve at the inlet
to the heat exchanger in order to bleed the heat exchanger as needed, in particular before the beginning of
the heating season (Figure 3). The time it takes to heat up using the heat exchanger depends on the
temperature and flow of water in the hot water heating system. A combined heater is made in universal
design – depending on the need of connecting the closing valves to the heating element either from the
right, or from the left.
It is recommended to install stop valves on the heating water inlet and outlet (for possible
dismantling of the heater).
The valves have to be as close to the heater as possible to avoid
higher thermal losses.

- 14 -
Figure 6
2.6 FIRST COMMISSIONING
After connecting the heater to the water supply, the hot water heating system, the electric
network, and after testing its safety valve (based on the valve manual attached), the heater
may be put into operation. Before opening the power supply, the tank must be filled with
water. The process of first heating must be executed by licensed professional who has to
check it. Both the hot water outlet pipe and safety armature parts may be hot.
During the heating process the pressurised connection water that increases its volume due
to heating must drip off the safety valve. In non-pressurised connection water drips off the
overflow combination faucet. When heating is finished, the set temperature and the actual
temperature of consumed water should be roughly equal. After connecting the heater to the
water main and electrical power system, and after checking the safety valve (following the
instructions attached to the valve), the heater can be put into operation.

- 15 -
Procedure of putting the heater into operation:
1. Check both water and electric installation; for combined heaters, check also the installation to
the hot water heating system. Check proper placement of thermostat sensors. The sensors
must be inserted all the way in; first the thermostat and then the safety fuse.
2. Open the hot water valve on the combination faucet.
3. Open the cold water inlet valve to the heater.
4. As soon as the water starts running through the hot water valve, the heater is filled and the valve
can be closed.
5. In case of leakage (of flange lid), we recommend that the flange lid bolts are fastened.
6. Screw down the electric installation guard.
7. When heating service water with electric energy from the hot water heating system, open the
heating water inlet and outlet valves, possibly de-aerate the heat exchanger.
8. When commencing operation, flush the heater until the cloudiness in the water is gone.
9. Make sure to fill in properly the warranty certificate.
2.7 PUTTING OUT OF SERVICE, DISCHARGE
If the hot water heater is put out of service for a longer time, or if it is not going to be used it
has to be drained and disconnected from the electric supply network on all poles. The switch
for the supply lead or the fuse cut-outs have to be shut off.
At places with permanent risk of frost the hot water heater must be drained before the cold
season starts if the appliance remains out of service for several days and if the power supply
is disconnected.
Drainage of utility water shall be performed after closing the shut-off valve in the cold water
supply piping (through the discharge valve for safety valve combination), and with
simultaneous opening of all hot water valves of connected fittings. Hot water may outflow
during the drainage! If there is a risk of frost it has to be considered that not only the water
in the hot water heater and in the hot water piping may get frozen but also the water in the
entire cold water supply piping. It is therefore advisable to drain all fittings and piping that
carry water, up to the part where the house water meter is installed (connection of the
house to water main) which is not jeopardised by frost. When the tank is to be used again, it
has to be filled with water and one needs to make sure that the water flowing out at the
hot water valves did not contain any bubbles.

- 16 -
2.8 INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE
During the heating process the water that increases its volume during the heating must drip
off the safety valve outlet (in non-pressurised connection this water drips off the
combination faucet valve). In full heating (about 65oC) the volumetric water gain is approx.
3% of the tank capacity. The function of the safety valve has to be checked regularly (based
on the information contained in the attached safety valve manual). In common operation,
such a check needs to be implemented at least once a month, and after each heater
shutdown that exceeds 5 days.
Caution! In doing so, the cold water supply pipe and the connection fitting of the tank may
get heated! If the hot water heater does not work, or if hot water is not withdrawn, no
water shall drip off the safety valve. If water drips, then the pressure in the supply piping is
either too high, or the safety valve is defective. Please call a specialised plumber
immediately!
If water contains too many minerals, an expert has to come to remove the scale that forms
inside the tank, as well as free sediments. This has to be performed after one or two years of
operation. Repeated heating causes lime scale settling on the receptacle walls and mostly on
the lid of the flange. Lime scale settling depends on hardness of heated water, its
temperature and on the volume of hot water used.
We recommend checking and cleaning the tank from lime scale and eventual replacement
of the anode rod after two years of operation. The anode life is theoretically calculated for
two years of operation; however, it changes with water hardness and chemical composition
in the place of use. Based on such an inspection, the next term of anode rod exchange may
be determined. Have a company in charge of service affairs deal with the cleaning and
exchanging of the anode.
When discharging water from the heater, the mixing valve battery for hot water must be
open in order to avoid creating underpressure that would prevent water discharge. Cleaning
is carried out through the hole in the flange by: draining the boiler, dismantling the flange lid
and cleaning the tank. A new sealing has to be used for re-fitting. Since the inside of the
heater has special enamel, the surface of which must not get in contact with a scale
removing agent – do not work with a lime pump. Remove the lime layer with a timber and
suck it off, or wipe it off with a clout. After that, the appliance must be rinsed thoroughly and
the heating process is checked the same as during the initial putting in operation. Do not use
any abrasive cleaning agents or dye thinners to clean the outer shell of the heater (such as
cellulose thinner, trichlor, and the like). For cleaning use a wet clout and add a few drops of
liquid cleaning agent for household applications.

4IMPORTANT NOTICES
4.1 INSTALLATION REGULATIONS
-Without a confirmation of performed electrical installation issued by an authorised company, the
warranty certificate shall be void.
-Check and exchange the Mg anode regularly.
-You have to apply for approval of a local power supplier to connect the heater.
-No stop valves can be put between the heater and the safety valve.
-If the overpressure in the water main exceeds 0.48 MPa, a pressure control valve must be mounted
before the safety valve.
-All hot water outputs must have a combination faucet.
Adjusting the thermostat knob to the left backstop does not mean permanent shutoff of the
heating element. When the heater is in use without blocking the daily rate, we do not
recommend the temperature to be set above 55°C. Select the "ECO

-Before filling the heater with water for the first time, it is recommended to fasten the flange
connection nuts of the tank.
-It is not allowed to handle the thermostat, aside from temperature resetting with a control button.
-All electric installation handling, adjustment and replacement of the regulation elements shall only
be performed by an authorised service company.
-The thermal fuse must not be turned off! In case of thermostat defect, the thermal fuse interrupts
electric power input to the heating element if the water temperature in the heater exceeds 90 °C.
-As an exception, the thermal fuse may also switch off due to water overheating caused by
overheating the hot water heating system boiler.
-We recommend you operate the heater with one type of energy.
Both the electric and water installation must follow and meet the requirements and
regulations relevant in the country of use!
