What is the capacity of the Gorenje TG120NG water heater?

The TG120NG has a capacity of 110.7 liters.

What safety valve should be installed?

A safety valve with a rated pressure of 0.6 MPa (6 bar) must be installed on the inlet pipe. The outlet must be open to the atmosphere and face downwards in a non-freezing area.

Can I install a stop valve between the water heater and the safety valve?

No, do not install a stop valve between the water heater and the safety valve, as it will impair the pressure protection.

How do I fill the water heater before first use?

Open the hot water tap on the mixing faucet and fill the heater until water flows from the outlet. Only then connect to the power supply.

What is the recommended thermostat setting?

The manufacturer sets the thermostat to 'eco' for optimal energy consumption and minimal limescale. It can be adjusted between 10 °C and 65 °C.

How often should the magnesium anode be inspected?

The anode must be inspected regularly as per the warranty certificate (period not exceeding the stated interval). Authorized service providers check wear and replace if necessary.

What should I do if water leaks from the safety valve?

Slight dripping during heating is normal due to thermal expansion. If excessive, check if the valve is blocked. Install a drain funnel or an expansion tank (3 L) to manage dripping.

Can I repair the water heater myself?

No, never attempt repairs yourself. Contact an authorized service workshop for any defects.

What is the heating time for the TG120NG?

Heating from 10 °C to 65 °C takes approximately 3 hours and 46 minutes.

How do I drain the water heater for long-term storage or freezing risk?

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 try to fix any defects of the water heater 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.

Dear buyer, thank you for purchasing our product. Prior to the installation and first use of the electric water heater, please read these instructions carefully.

This water heater has been manufactured in compliance with the relevant standards and tested by the relevant authorities as indicated by the Safety Certificate and the Electromagnetic Compatibility Certificate. The technical characteristics of the product are listed on the label affixed between the inlet and outlet pipes. The installation must be carried out by qualified staff. All repairs and maintenance work within the water heater, e.g. lime removal or inspection/replacement of the protective anticorrosion anode, must be carried out by an authorised maintenance service provider.

INSTALLATION

The water heater shall be installed as close as possible to the outlets. When installing the water heater in a room with a bathtub or shower, take into account the requirements defined in IEC Standard 60364-7-701 (VDE 0100, Part 701). It has to be fitted to the wall using appropriate wall screws with a minimum diameter of 8 mm. A wall with a poor load-bearing capacity must be properly reinforced where the heater will be installed. The water heater may only be fixed upon the wall vertically. We recommend the distance between the water heater and the ceiling is large enough to allow simple replacement of the Mg anode (see dimension G in the Installation Drawing), in order to avoid unnecessary dismounting of the heater during the servicing intervention.

Connection and installation dimensions of the water heater [mm]

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.

CONNECTING THE WATER HEATER TO 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 of 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 manufacturers 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.

UPOZORENJE: Pre svake intervencije u unutrašnjosti bojlera obavezno isključite bojler iz električne mreže!

UPOTREBA I ODRŽAVANJE

Posle priključivanja na vodovodnu i električnu mrežu bojler je spreman za upotrebu. Temperaturu vode u bojleru automatski reguliše fabrički podešen termostat.

Temperatura se može podešavati okretanjem vijka na termostatu u unutrašnjosti bojlera. Područje podešavanja se kreće od 10 °C do 65 °C +5 °C/-0 °C. Ne preporučujemo vam da menjate fabrički podešenu temperaturu jer je to temperatura na kojoj je potrošnja električne energije ekonomična, a taloženje kamenca najmanje. Delovanje električnog elementa za grejanje pokazuje kontrolna svetiljka. Grejač ima na ivici bimetalni termometar, koji se pokreće u smeru kazaljke na satu u desno, kada je u grejaču prisutna topla voda. Termometar okvirno prikazuje temperaturu vode i nije merni instrument. Ako bojler ne nameravate da koristite duže vreme, isključite ga iz električne mreže. Ako postoji opasnost da se voda u bojleru zamrzne, ispustite vodu iz bojlera. Voda iz bojlera se ispušta kroz dovodnu cev bojlera. U tom cilju preporučljivo je prilikom ugradnje između sigurnosnog ventila i dovodne cevi grejanja namestiti poseban "fiting" (T-deo) ili ispusni ventil. Bojler takođe možete da ispraznite i neposredno kroz sigurnosni ventil pomeranjem ručice, odnosno obrtne kapice ventila u položaj kao prilikom proveravanja rada. Pre pražnjenja isključite bojler iz električne mreže i zatim otvorite ručicu za toplu vodu na priključenoj bateriji za mešanje. Posle pražnjenja vode kroz dovodnu cev, u bojleru ostaje manja količina vode koja ističe prilikom odstranjivanja grejne prirubnice kroz otvor grejne prirubnice. Kućište bojlera čistite blagim rastvorom praška za pranje. Ne upotrebljavajte razređivače ni gruba sredstva za čišćenje.

Redovnim servisnim pregledima obezbedićete besprekoran rad i dug životni vek bojlera. Garancija za prerđavanje kotla važi samo ako ste obavljali propisane redovne preglede istrošenosti zaštitne anode. Period između pojedinih redovnih pregleda ne sme biti duži nego što je navedeno u garancijskoj izjavi. Pregledi moraju biti obavljeni od strane ovlašćenog servisera, koji će Vam pregled evidentirati na garancijskom listu proizvoda. Prilikom pregleda, proverava istrošenost antikorozivne zaštitne anode i po potrebi očisti vodeni kamenac koji se, s obzirom na kvalitet, količinu i temperaturu potrošene vode sakuplja u unutrašnjosti bojlera. Servisna služba će vam posle pregleda bojlera, s obzirom na utvrđeno stanje, preporučiti i datum sledeće kontrole.

Molimo da eventualne kvarove ne popravljate sami nego da o njima obavestite najbližu servisnu službu.
