Instructions for Use 9

Upute za upotrebu 15

The appliance may be used by children older than 8 years old, elderly persons and persons with physical, sensory or mental disabilities or lacking experience and 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 perform maintenance on the appliance without supervision.

⚠️ Installation should be carried out in accordance with the valid regulations and according to the instructions of the manufacturer and by qualified staff.

In a closed, pressurised system of installation, it is obligatory to install a safety valve on the inlet pipe with a rated pressure of 0.6 MPa (6 bar), 0.9 MPa (9 bar) or 1.0 MPa (10 bar) (see the label), which prevents the elevation of pressure in the boiler 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 water heater and the safety valve, because it will impair the pressure protection of the heater!

⚠️ Before connecting it to the power supply, the water heater must be filled with water!

The heater is equipped with an additional thermal cut-off for protection in case of failure of the operating thermostat. In this case, however, the temperature of the water in the heater can reach up to 130 °C according to the safety standards. During the water supply installation, the possibility of temperature overloads should be taken into account.

⚠️ If the heater is to be disconnected from the power supply, please drain any water from the heater to prevent freezing.

Please do not attempt to repair the water heater yourself. Contact the nearest authorized service provider.

Connection and installation dimensions of the water heater [mm]

CONNECTION TO THE WATER SUPPLY

The water heater connections for water inlet and outlet are color-coded. The cold water inlet is marked in blue, while the hot water outlet is marked in red.

The water heater can be connected to the water supply in two ways. The closed-circuit pressure system enables multiple points of use, while the open-circuit gravity system enables only a single point of use. The mixer taps must also be installed in accordance with the selected installation mode.

The open-circuit gravity system requires the installation of a non-return valve to prevent water from draining out of the tank if the water supply runs dry or is shut down. This installation mode requires the use of a cross-flow mixer tap. As heating water expands its volume, this causes the tap to drip. The dripping cannot be stopped by tightening it further; on the contrary, tightening can only damage the tap.

The closed-circuit pressure system requires the use of pressure mixer taps. 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 relief valve must be equipped with an outlet for atmospheric pressure.

The heating of water in the heater 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 of the safety valve. The drip can be piped to the 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 the existing plumbing does not enable you to pipe the dripping water from the safety valve into the drain, you can avoid the dripping by installing a 3-litre expansion tank on the inlet water pipe of the boiler.

In order to provide correct operation of the safety valve, periodical inspections of the relief valve must be carried out by the user to eliminate any limescale and check if the safety valve is 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 the valve). The valve is operating properly if the water comes out of the nozzle when the outlet is open.

Between the water heater and safety valve, no closing valve may be built in because it could impede the function of the safety valve.

The heater can be connected to the domestic water supply network without a pressure-reducing valve if the pressure in the network is lower than the nominal pressure. If the pressure in the network exceeds the nominal pressure, a pressure-reducing valve must be installed.

Before connecting it to the power supply, the water heater must be filled with water. When filling the heater for the first time, the tap for the hot water on the mixing tap must be opened. When the heater is filled with water, the water starts to run through the outlet pipe of the mixing tap.

CONNECTING THE WATER HEATER TO THE POWER SUPPLY NETWORK

Before connecting to the power supply network, install a power supply cord in the water heater, with a minimum diameter of 1.5 mm² (H05VV-F 3G 1.5 mm²). To do this, the protective plate must be removed from the water heater.

Connecting the heater to the power supply network must take place in accordance with the standards for electric appliances.

To comply with the national installation regulations, an all-pole

disconnect switch must be installed between the water heater and the power supply network.

CAUTION: Before any intervention into the interior of the water heater, disconnect it from the power supply network!

After connecting to the water and power supply, the heater is ready for use.

Temperature of water in the appliance is automatically controlled by the thermostat which is adjusted by the manufacturer. The adjustment can be modified by turning the adjustment screw upon the thermostat in the inner of the water heater. The adjustment range reaches between 10 °C and 65 °C +5 °C/-0 °C. We do not recommend any change of the manufacturer's adjustment, thus this ensures the most economical consumption of electric energy and the smallest excretion of lime-stone. The operation of electric immersion heater is shown by pilot light. On the casing of the water heater a bimetal thermometer is mounted, pointing clockwise (to the right) whenever there is hot water in the water heater. The thermometer only gives an approximate temperature of water and is not a measuring device.

When the heater shall not be used during a longer time, it must be disconnected from the electric network. At any risk for freezing of water in the water heater, the water must be emptied from it. Water from the heater is drained through the inlet pipe of the heater. For this purpose, a special fitting (T-fitting) must be mounted between the relief valve and the heater inlet pipe, or a discharge tap. The heater can be discharged directly through the relief valve, by rotating the handle or the rotating valve cap to the same position as for checking the operation. Before discharge, make sure the heater is disconnected from the power supply, and open the hot water on the connected mixer tap. After discharging through the inlet pipe, there is still some water left in the water heater. The remaining water will be discharged after removing the heating flange, through the heating flange opening.

The external parts of the water heater can be cleaned with a mild detergent solution. Do not use solvents and abrasives.

With regular service inspections you will ensure faultless functioning and long life of the heater. Tank corrosion warranty applies only if all the prescribed regular inspections of the protective anode wear have been made. The period between regular inspections should not be longer than stated in the warranty certificate. Inspections should be carried out by authorised service providers that will record each inspection on the warranty statement of the product. Upon inspection the service provider will inspect the amount of wear on the anti-corrosion anode and, if

necessary, clean the limescale that accumulates depending on the quality, quantity and temperature of the water inside the heater. The service provider will also recommend the date for the next inspection depending on the condition of the heater.

Never try to repair any possible faults of the water heater by yourself, but inform about it the nearest authorised service workshop.

USE AND MAINTENANCE

After connecting to the water supply and electrical mains, the water heater is ready for use. The water temperature in the heater is automatically regulated by a factory-set thermostat.

The temperature can be adjusted by turning the screw on the thermostat inside the water heater. The adjustment range is from 10 °C to 65 °C +5 °C/-0 °C. We do not recommend changing the factory-set temperature, as it is the temperature at which electricity consumption is economical and limescale deposition is minimal. The operation of the electric heating element is indicated by a control light. The heater has a bimetallic thermometer on its edge, which moves clockwise to the right when hot water is present in the heater. The thermometer gives an approximate indication of the water temperature and is not a measuring instrument. If you do not intend to use the water heater for an extended period, disconnect it from the electrical mains. If there is a risk of the water in the heater freezing, drain the water from the heater. The water from the heater is drained through the inlet pipe. For this purpose, it is advisable to install a special "fitting" (T-piece) or drain valve between the safety valve and the inlet pipe during installation. You can also empty the heater directly through the safety valve by moving the lever or rotating cap of the valve to the position used for checking operation. Before draining, disconnect the heater from the electrical mains and then open the hot water tap on the connected mixing faucet. After draining the water through the inlet pipe, a small amount of water remains in the heater, which flows out when removing the heating flange through the heating flange opening. Clean the heater casing with a mild solution of washing powder. Do not use thinners or abrasive cleaning agents.

Regular servicing will ensure flawless operation and a long service life for the water heater. The warranty for the tank against corrosion is valid only if you have performed the prescribed regular inspections of the sacrificial anode wear. The interval between regular inspections must not exceed the period specified in the warranty statement. Inspections must be carried out by an authorized service technician, who will record the inspection in the product warranty card. During the inspection, the technician checks the wear of the anticorrosion sacrificial anode and, if necessary, cleans the limescale that accumulates inside the heater depending on the quality, quantity, and temperature of the water used. After the inspection, the service department will recommend the date of the next check based on the condition found.

Please do not attempt to repair any faults yourself; instead, notify the nearest service department.
