CONNECTION TO THE WATER SUPPLY

Connect to the water supply according to the connection markings from the previous chapter.

For safety, it is necessary to install a safety valve or safety fitting on the supply pipe that prevents the pressure in the boiler from increasing by more than 0.1 MPa (1 bar) above the nominal pressure. The drain opening on the safety valve must have an outlet to atmospheric pressure. When heating water in the water heater, the water pressure in the boiler increases to the limit allowed by the safety valve. Since the return of water to the water supply is prevented, dripping from the drain opening of the safety valve may occur. You can direct this water to a drain via a water container placed below the safety valve. The drain pipe installed below the discharge element on the safety valve must be directed straight down and in a location where it does not freeze.

If you wish to avoid dripping from the safety valve, you must install an expansion vessel for sanitary water with a capacity of at least 5% of the water heater's volume on the valve's supply pipe.

For proper operation of the safety valve, it is necessary to periodically perform checks, remove scale, and verify that the safety valve is not blocked. When checking by moving the handle or unscrewing the valve nut (depending on the valve type), you must open the drain from the safety valve. During this, water must flow through the valve's discharge nozzle, indicating that the valve is in perfect condition.

WARNING: Before any access to the interior of the water heater, you must disconnect it from the electrical supply! Access may only be carried out by qualified personnel.

CONNECTION TO OTHER HEAT SOURCES

The water heater allows heating of sanitary water through heat exchange with various energy sources (e.g., central heating, solar energy, ...).

The appliance may be used by children aged 8 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 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. Please do not try to fix any defects of the storage tank on your own. Call the nearest authorised service provider.

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.

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

Before connecting the storage tank to the power supply network, a connection cable with a minimum cross-section of at least 1.5 mm² (H05VV-F 3G 1.5 mm²) for a 3kW heating element and 2.5 mm² for a 6kW heating element (H05VV-F 5G 2.5 mm²) must be installed in it and the protection cover must be removed.

This is done by pulling out the knob on the thermostat axis and unscrewing two screws.

An all-pole disconnect device must be installed in the electric installation to comply with the National Installation Regulations.

WARNING: Before any intervention into the interior of the storage tank disconnect it from the power supply! All interventions must be carried out by qualified staff only!

CONNECTION TO ALTERNATIVE SOURCES OF HEATING

The hot water storage tank enables the water for sanitary use to be heated by alternative sources of energy (e.g. central heating, solar power etc.) by installing a Heat Exchanger.

Examples of connecting the hot water storage tank to various sources of heating are shown in the drawings below.

Image 8: Connection to the central heating hot-water system

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 electric heating element is designed for backup heating of water only. The temperature is set by turning the knob in a clockwise direction to reach the desired temperature level.

* - Protection against freezing, temperature around 10 °C. - Water temperature around 35 °C. eco - Water temperature around 55 °C. - Water temperature around 85 °C.

The thermometer shows the in-situ temperature, whereas by turning the knob on the thermostat the water temperature in the lower part of the storage tank is set. Thus, these two temperatures may vary.

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 alcohol or 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.
