1TECHNICAL SPECIFICATION OF PRODUCT
1.1 FUNCTION DESCRIPTION
The water heater as well as the storage tank (thereinafter the appliance) is designed for accumulation
heating of service water using electricity or thermal energy via an exchanger (for the combined design
only). Water is heated by an electric element (or a heat exchanger) in an enamelled thermally insulated
accumulator at the time defined by the power supplier. The element is at the time of heating controlled by
a thermostat the temperature of which can be adjusted continuously (within the range between 5°C and
74°C). 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 appliance.Hot water flows out through the top part, and water flowing in
remains in the bottom part of the appliance.Pressure principle allows hot water withdrawal at any place
from the appliance (Figure 5).
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 appliance 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 a top-quality polyurethane foam with
zero CFCs content. Adjust the temperature of the appliance'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 electric element's pit.

- 5 -
1.2.3 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 appliance, and at 20°C
in its ambient area. The resulting value is expressed in [kWh/24h] and indicates the
amount of power needed to maintain the set temperature.
1.3 DESIGN AND GENERAL DIMENSIONS
The vessel is made of a steel plate and tested by 0.9 MPa overpressure. The inside of the receptacle is
enamelled. A flange is welded onto the lower bottom of the receptacle with a flange lid screwed onto it. A
sealing ring is inserted between the flange lid and the flange. Thermo wells for thermostat sensors and
thermometer installation are placed in the flange lid. Anode rod is mounted on 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. Heat exchanger(s) is/are
welded onto the pressure tank.

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 appliance has to be mounted
at a convenient place, it means that the appliance must be easily available for potential
necessary maintenance, repair or replacement, as the case may be.
We would like to emphasise that the appliance 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 devices
was installed with the appliance, or the thermostat to be set to 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
appliance shall only be mounted in vertical position so that the lower side of the appliance
was placed at least 600 mm above the floor (Figure 1). In appliances, 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 appliances with this material. Th
e 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
Connection of appliances to plumbing fixtures is illustrated on (Figure 4, Figure 6). For
potential disconnection of the appliance, the service water inlets and outlets must be
provided with scre
w coupling Js 3/4“. Safety valve is mounted on the cold water inlet
identified with a blue ring.
Each hot service water pressure appliance must have a safety valve with a membrane spring.
Nominal clearance of safety valves is defined in the standards. The appliances are not
equipped with a safety valve. The safety valve must be easily accessible, as close to the
appliance as possible. The input pipes must have at least the same clearance as the safety
valve. The 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 appliance.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 appliance 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

- 11 -
appliance and the safety valve. During the assembly, follow the guide provided by the safety
equipment manufacturer.
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 to the right. 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 appliance 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 appliance,
use a recommended drain valve. First, close water input into the appliance. 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 appliance draining and hot
water penetrating back into the water main. We recommend that the hot water distribution
from the appliance was as short as possible to minimise heat losses.
Required pressures - Table 3. We recommend that the hot water distribution from the appliance was as
short as possible to minimise heat losses

2.4 ELECTRIC WIRING
2.4.1 ELECTRIC INSTALLATION GENERAL INFORMATION
Perform the connection according to the scheme. Factory connection must not be changed! (Figure 5)In
the electric wiring casing remove the partition corresponding with the input wire diameter of ∅8 or ∅10
(Figure 4). The degree of protection of electric parts of the appliance is IP 45. Power input of electric
element is 4000 W.
Figure 4
It is necessary to observe the below requirements during the electric wiring:
•
The electric wiring scheme is attached to the appliance on the side of the electric
installation guard (Figure 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 appliance is connected to the 3/N/PE ~ 230V/50Hz electric network using a fixed
moving conductor with a switch that turns off all network poles and the circuit
breaker (protector).
•Installations in bathrooms, lavatories and showers must comply with the standards.
•The degree of protection of electric parts of the appliance is IP 45.
•Respect the rules of protection against electrical injuries in accordance with
Standards.
Figure 5

2.5 CONNECTION OF APPLIANCE TO HOT WATER HEATING
SYSTEM
a) Water heating by electric energy
After the appliance 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 appliance has to be switched off. In combined versions, the
stop valve on the inlet to the exchanger has to be closed, which prevents heating 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 a 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 of heating using the heat exchanger depends on the temperature
and flow of water in the hot water heating system. An appliance 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 appliance). The valves have to be as close to the appliance as possible to
avoid higher thermal losses.

- 14 -
Figure 6
2.6 FIRST COMMISSIONING
After connecting the appliance 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
appliance 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 appliance to
the water main and electrical power system, and after checking the safety valve (following
the instructions attached to the valve), the appliance can be put into operation.

Procedure of putting the appliance into operation:
1. Check both water and electric installation; for storage tanks, check the installation to a hot water
heating system. Check proper placement of operating and safety thermostat sensors. The sensors
must be inserted all the way in; first the operating and then the safety thermostat.
2. Open the hot water valve on the combination faucet.
3. Open the cold water inlet valve to the appliance.
4. As soon as the water starts running through the hot water valve, the appliance is filled and the
valve can be closed.
5. In case of a leakage (flange lid), we recommend fastening the flange lid bolts.
6. Fasten the electric installation cover.
7. When heating service water with electric energy from the hot water heating system, turn the
electricity off and open the valves of heating water input and output, possibly de-aerate the
exchanger.
8. When commencing operation, flush the appliance 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 appliance 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 appliance 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 service 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 appliance 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 appliance
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 appliance 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. Repetitive water heating causes limestone
sediment on both the tank walls and chiefly the flange lid. The sedimentation depends on
the hardness of water heated, its temperature, and amount of hot water consumed.
We recommend checking and cleaning the tank from 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 the company in charge of service affairs clean and
exchange the anode.
When discharging water from the appliance, the combination faucet valve for hot water
must be open in order to avoid creating under pressure that would prevent water discharge.
This has to be performed after one or two years of operation. The 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 vessel 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 appliance (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.
