WARNINGS
The appliance may be used by children aged 3 and older and persons with physical, sensory or
mental disabilities or lacking experience or knowledge, if they are under supervision or taught about
safe use of the appliance and if they are aware of the potential dangers. Children aged from 3 to
8years are only allowed to operate the tap connected to the storage tank.
Children should not play with the appliance.
Children should not clean or maintain the appliance without supervision.
The installation should be performed in accordance with the valid regulations and the instructions of
the manufacturer. It should be performed by a professionally trained installation expert.
It is obligatory to install a safety valve with a rated pressure of 0.6 MPa (6 bar), 0.9 MPa (9 bar) or
1.0 MPa (10 bar) – see the label – on the inlet pipe of the hot water storage tank to prevent the
elevation of pressure in the tank 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 non-freezing 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 hot water storage tank and the safety valve, because it will
impair the pressure protection of the storage tank!
Before connecting the heater to the power supply, the storage tank must be filled with water!
The storage tank is protected in case of failure of the operating thermostat with an additional thermal
cut-out. In case of thermostat failure water in the storage tank may reach the temperature of up to
130°C in accordance with safety standards. The possibility of such temperature overload should be
taken into consideration in the execution of plumbing.
Should you choose to disconnect the power, the storage tank should be drained thoroughly before the
onset of freezing conditions.
Water from the storage tank is drained through the inlet pipe of the tank. For this purpose, a special
fitting (T-fitting) with an outlet valve must be mounted between the safety valve and the inlet pipe.
To avoid hazard, damaged power cord may only be replaced by the manufacturer, authorized service
technician, or other authorized person.
In the electrical installation, please install a disconnect switch to separate all poles from the power
supply network in accordance with the national regulations.
Please do not try to fix any defects of the storage tank 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.

CONNECTION TO THE WATER SUPPLY
Connection to water supply should be made according to the markings for the connections, as defined in the previous Chapter.
For safety reasons the supply pipe must be fitted with a safety valve or, alternatively, a valve of the safety class that prevents the
pressure in the tank from exceeding the nominal pressure by more than 0.1 MPa (1 bar). The outlet opening on the safety valve must
be equipped with an outlet for atmospheric pressure. The heating of water in the storage tank 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 opening of the safety valve. The drip can be piped to a 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.
In case you want to avoid water dripping from the safety valve, an expansion tank for domestic water with at least 5 % of the volume
of the storage tank should be installed on the inlet pipe of the storage tank.
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. 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 valve). The valve is operating properly if the water comes out of the nozzle when the outlet is open.
Image 2: Closed (pressure) system
The storage tank can be connected to the domestic water supply network without a pressure regulator if the pressure in the network is
lower than the nominal pressure (see the label). If the pressure in the network exceeds the nominal pressure, a pressure regulator
must be installed.

CONNECTION TO THE POWER SUPPLY NETWORK
The heater is powered directly from the heating system control unit with a regulation voltage of 220–240 V, 50/60 Hz. To connect the
electric heater and the superordinate control unit (heat pump, gas boiler, solid fuel furnace, oil boiler etc.), a connecting cable must be
installed with a diameter of min. 2.5 mm2 (H05VV-F 3G 2.5 mm2), so the protective cover must be removed. Cable connection, which
is carried out directly to the clamps of the thermostat and grounding to the heater flank, is shown in the sketch below.
The built-in thermostat of the electric heater is pre-set to the maximum (75 °C). When setting the superordinate control unit, you are
limited to this temperature. If the limit temperature is exceeded, the built-in thermostat in the hot water storage tank will be shut off.
An all-pole disconnect device must be installed in the electric installation to comply with the National Installation Regulations.
CAUTION: Prior to any intervention in the interior, the hot water storage tank must be disconnected from power supply!
Interventions may only be carried out by authorised professionals!

USE AND MAINTENANCE
The hot water storage tank is ready for use once it has been connected to water and electricity and other heating sources. The usual
main sources for heating domestic water are central heating or solar power; in this case any regulation of water heating is performed
in the heating system.
The built-in electrical heater is only intended for auxiliary heating of water and is controlled by an external unit.
In case of exposure to sub-zero temperatures, the water should be drained from the storage tank thoroughly before the onset of
freezing conditions. Water from the storage tank is drained through the inlet pipe of the storage tank. For this purpose, a special fitting
(T-fitting) with an outlet valve must be mounted between the safety valve and the inlet pipe. Before discharge make sure the storage
tank is disconnected from the power supply, close the inlet of cold water into the storage tank, open the hot water tap on the
connected mixer tap and wait for the water in the storage tank to cool down. After discharging through the inlet pipe there is still some
water left in the storage tank.
The external parts of the water heater may be cleaned with a soft cloth and mild cleaning fluids. Do not use cleaning fluids containing
abrasives.
Regular preventive maintenance inspections ensure faultless performance and long life of your storage tank. Tank Warranty is subject
to regular inspections of the wear of the protective anode. The period between individual regular inspections should not be longer
than specified in the Guarantee statement. Inspection should be carried out by an authorised maintenance service provider recording
the inspection on the Guarantee Certificate of the product. During the inspection, the wear of the corrosion protection anode will be
inspected and any limestone built up in the interior of the storage tank, depending on the quality, quantity and temperature of used
water, will be removed as required. After inspecting the storage tank, the maintenance service provider will also recommend the date
of the next inspection according to the ascertained status.
Please do not try to fix any defects of the storage tank on your own. Call the nearest authorised service provider.
