1APPLIANCE TECHNICAL SPECIFICATION
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. Water is heated by an electric
element or a heat exchanger in an enamelled thermally insulated vessel 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 vessel is then used for the consumption. The
appliance keeps constant pressure of water from the water main. Is the combination faucet hot water valve
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 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 heat exchanger.

- 5 -
EMERGENCY POWER CONSUMPTION
If no heated water is taken from the appliance, 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 units [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 vessel is
enamelled. A flange is welded onto the bottom of the vessel with a flange lid screwed to it.
A sealing ring is inserted between the flange lid and the flange. Thermo wells 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 vessel. The heat exchanger is only intended
for the heating circuit.

2OPERATION AND FITTING INSTRUCTIONS
2.1 OPERATING CONDITIONS
The appliance 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. Temperature in the
appliance 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 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 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 3).
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.
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.

- 9 -
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 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 appliance must have a safety valve with a membrane spring.
The safety valve must be easily accessible, as close to the appliance as possible. The inlet
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

- 10 -
system. No stop valves can be put between the appliance and the safety valve. During
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 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 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 the recommended drain valve. First, close the water supply 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.
Required pressures - Table 4. We recommend that the hot water distribution from the appliance was as
short as possible to minimise heat losses.

2.4 ELECTRIC INSTALLATION
2.4.1 ELECTRIC INSTALLATION GENERAL INFORMATION
The electric wiring scheme is attached to the water heater on the side of the electric
installation guard (figure 4).
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 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 standards.
The degree of protection of electric parts of the heater is IP 45.
Adhere to the protection against electric shock injury according to standard.

Figure 4
2.5 CONNECTION OF APPLIANCE TO HOT WATER 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

- 12 -
(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 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 (Fig. 1) 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 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.
Figure 5

- 13 -
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 appliance 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 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 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. 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 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 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 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 appliance and in the hot water piping may get frozen but also the water in the entire

- 14 -
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 appliance 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.
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 65 °C) the volumetric water gain is approx.
3% of the vessel 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 appliance
may get heated! If the 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 vessel, as well as free sediments. This has to be performed after one or two years
of operation. Repetitive water heating causes limestone sediment on both the vessel 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 appliance 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 mixing valve battery for hot water must
be open in order to avoid creating underpressure that would prevent water discharge. The
cleaning is carried out through the hole in the flange by: draining the boiler, dismantling the
flange lid and cleaning the vessel. 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.
