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 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.
In a closed, pressurised system of installation, it is obligatory to install a safety valve with a rated pressure of 0.6 MPa (6 bar), 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 functioning of the safety valve!
Before connecting it to the power supply, the water heater must be filled with water!
Water can be drained from the water heater through the boiler inlet pipe. For this purpose it is advisable to install a special element or outlet valve between the inlet pipe and safety valve.
⚠️ Please do not try to fix any defects of the water heater on your own. Call the nearest authorised service provider.

CONNECTION TO THE WATER SUPPLY
The water heater connections for the inlet and outlet of water are colour-coded. The inlet of cold water is marked with blue colour, while the hot water outlet is marked with red colour.
The water heater can be connected to the water supply in two ways. The closed-circuit pressure system enables several points of use, while the open-circuit gravity system enables a single point of use only. 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 in order to prevent the water from draining out of the tank in the event of the water supply running dry or being shut down. This installation mode requires the use of a cross-flow mixer tap. As the heating of water expands its volume, this causes the tap to drip. The dripping cannot be stopped by tightening it further; on the contrary, the 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.
The TGRK combined water heater has an additional tubular heat transmitter for heating domestic water using other energy sources (e.g. central heating, solar collector, heat pump). The heating system using an electric heater and the system using the heat transmitter can work simultaneously or individually. The combined water heater is connected to the water pipeline and to an additional energy source.
The inlet of the heating medium into the heat transmitter is labelled with red paint while the outlet is labelled with blue paint.
WARNING: When the temperature of the additional heat source drops and circulation
of water through the transmitter is enabled, uncontrolled reduction of heat can occur in the water heater. When connecting the appliance to other heat sources, the temperature regulation of the additional source must be carried out properly. The temperature switch of the regulation should not be inserted through the connection cable discharger.
The TGRK heater can also be connected to the hot water circulation line. The hot water circulation line allows warm water to always be available everywhere at once.
Connect the return line of hot water to the connection on top of the heater. Before connecting, please remove the plastic cap and unscrew the sealing plug on top of the heater. The return line elements can be purchased at our authorised service providers.
WARNING: The hot water return line must be installed before filling the heater with water. The use of circulation line results in additional heat losses in the water heater.
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 min. diameter of 1.5 mm^2 (H05VV-F 3G 1.5 mm^2 ). 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 poles disconnect switch must be installed between the water heater and the power supply network.

Electric installation
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.
By turning the thermostat knob, water temperature can be set between 25^ C and 65^ C. We recommend that the knob be set to the position "eco" ensuring the most economic operation of the water heater. This way, the water temperature is
maintained at 55 °C while the operation also results in less lime sediment as well as in less heat losses than is the case at higher temperatures. During the operation of an electric heater can hear noise in the water heater. The light indicator shows the operation of the heating element. 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. When the water heater is not in use for longer periods of time, it should be protected from freezing by setting the temperature to " *". Do not disconnect the power. Thus the temperature of water is maintained at about 10 °C. Should you choose to disconnect the power, the water heater should be thoroughly drained before the onset of freezing conditions. 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.
Regular preventive maintenance inspections ensure faultless performance and long life of your heater. The first of these inspections should be carried out by the authorised maintenance service provider about three years from installation in order to inspect the wear of the protective anticorrosion anode and remove the lime coating and sediment as required. The lime coating and sediment on the walls of the tank and on the heating element is a result of quality, quantity and temperature of water flowing through the water heater. The maintenance service provider shall also issue a condition report and recommend the approximate date of the next inspection.
Never try to repair any possible faults of the water heater by yourself, but inform about it the nearest authorised service workshop.
