Frequently Asked Questions - GT15U GORENJE

How do I set the water temperature?

Turn the thermostat knob on the front of the protective cover. You can set it between the '*' frost protection position and the '●' position (approx. 75°C). For optimal economy, use position 'e' (approx. 35°C for GT15). To adjust the maximum temperature, insert a screwdriver into slot 1, remove the button cover, and set the limiter to the desired value: C=35°C, B=45°C, A=55°C, O=75°C. Then replace the cover.

What is the frost protection mode?

Set the thermostat to the '*' position and do not disconnect the power. The heater will maintain water temperature at about 9°C to prevent freezing. If you disconnect the power, you must drain the water heater completely.

How do I install the safety valve?

In a closed pressurized system, install a safety valve on the inlet pipe with a rated pressure matching the heater's label (0.6, 0.9, or 1.0 MPa). The outlet opening must face downward and be in a non-freezing area. Do not install any shut-off valve between the heater and the safety valve. Regularly check the valve for limescale and ensure it is not blocked.

Can I install the heater myself?

No. Installation must be carried out by qualified staff according to valid regulations and manufacturer instructions. All repairs and internal maintenance must be performed by an authorized service provider.

What maintenance is required?

Regular preventive inspections every 36 months by an authorized service provider. They will check the protective anticorrosion anode and remove any limescale buildup. The anode wear and limescale depend on water quality, quantity, and temperature.

How do I drain the water heater?

To drain, disconnect the power and water supply. Open the hot water tap to allow air in. Water will drain through the inlet/outlet pipes. Drain completely if freezing is expected and the heater is not in use with power on.

Why is water dripping from the safety valve?

Dripping is normal in a closed pressurized system because water expands when heated and cannot return to the supply. The safety valve releases pressure. To reduce dripping, install an expansion tank (at least 5% of heater volume) on the inlet pipe. Do not tighten the valve further; that may damage it.

Can I use the heater with a pressurized water system?

Yes. The heater can be connected in a closed-circuit pressure system enabling multiple points of use. You must install a safety valve on the inlet pipe and use pressurized mixer taps. Alternatively, an open-circuit gravity system is possible for a single point of use with a non-return valve and instantaneous mixing tap.

What should I do if the heater is not heating?

First check that the power supply is connected and the thermostat is set above the '*' position. If the indicator light is off, the heater may have reached the set temperature. If it remains cold, contact an authorized service provider. Do not attempt repairs yourself.

How do I clean the exterior?

Use a mild detergent solution with a soft cloth. Do not use solvents, abrasive cleaners, or harsh chemicals.

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. Its technical characteristics are indicated on the label on the bottom of the heater next to the 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 should be installed in a room protected from the onset of freezing conditions and located as close as possible to the points of use. It has to be fitted to the wall using appropriate wall screws with a minimum diameter of 5 mm. With regard to the needs, you can chose execution above the sink (GT 5 O; GT 10 O; GT 15 O) or an execution under the sink (GT 5 U; GT 10 U; GT 15 U).

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.

In a closed, pressurized system pressurised mix taps should be used at the outlet points. To ensure safe operation of the heater a safety valve should be installed on the inlet pipe to prevent elevation of pressure for more than 0.1 MPa (1 bar) above the nominal pressure. The outlet opening on the safety 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.

To avoid water dripping from the safety valve, an expansion tank should be installed on the inlet pipe of the heater with the capacity of at least 5 % of the heater volume.

To ensure proper operation of the safety valve, periodical inspections must be carried out 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 the valve). The valve is operating properly if the water comes out of the nozzle when the outlet is open.

An open-circuit, non-pressurised system requires the installation of a non-return valve at the water inlet to prevent water draining out from the tank in the event of the water supply running dry. This installation mode requires the use of an instantaneous mixing 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.

No closing valve may be built-in between the water heater and return safety valve, because with it the pressure protection would be impeded! 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

The water heater shall be connected to the power supply by an electrical cable fitted with a plug. Should the existing cable replaced by a new, longer cable, the new cable should be connected to the lead and the wires screwed to the connectors. In this

case the water heater should first be disconnected from the power supply.

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! This intervention may only be performed by a trained professional!

The water heater is ready for use once it has been connected to water and power. By turning the thermostat knob on the front side of the protective cover, water temperature can be set between "*" frost protection position and "●" approx 75 °C position. We recommend that the knob be set to position "e" as this ensures the most economic operation of the water heater. This way the water temperature is maintained at approx. 35 °C by (GT 10 and GT 15) and and approx 41 °C by (GT 5). The operation of the heater at this temperature level also results in reduced build-up of calcium and lime, as well as reduced heat loss than is the case at higher temperatures. Due to safety reasons you can optionally set the highest temperature value of water in the heater. Proceed as follows:

a) Insert screwdriver in slot 1 and remove button cover 2, b) Set knob limiter 3 to any desired temperature value,

C: 35^ C
B: 45 °C
A: 55^ C
O: 75 °C
c) Replace knob cover 2 to the knob.

The operation of the heating element is indicated by the light indicator that stays on until the temperature in the tank has reached the set level or until the heater has been deliberately switched off. 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 the water in the tank is maintained at about 9 °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/outlet pipe of the heater.

The exterior of the water heater may be cleaned with a mild detergent solution. Do not use solvents and abrasive cleaners.

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 36 months from the date of installation in order to check the wear of the protective anticorrosion anode and remove any build-up of calcium and lime as required. The build-up of calcium and lime in the water heater depends on the quality, quantity and temperature of water flowing through the heater. The maintenance service provider shall also issue a condition report and recommend the approximate date of the next inspection.

In the event of the heater breaking down, you are kindly requested to contact the authorised maintenance service provider located closest to you. Please do not attempt to carry out any repairs yourself.

Delovanje električnog grejača pokazuje kontrolna svetiljka, koja svetli sve dok se voda u grejaču ne zagreje do izabrane temperature ili do namenskog isključenja. Ako nemate nameru da koristite bojler duže vremena, zaštitite njegov sadržaj od smrzavanja tako da ne isključujete električnu energiju, a dugme termostata podesite na položaj "*". Na tom podešavanju će bojler održavati temperaturu vode na

približno 9 °C. Ukoliko isključite bojler iz električne mreže, morate da ispustite vodu iz njega zbog opasnosti od smrzavanja vode. Voda iz bojlera se prazni kroz dovodnu/ odvodnu cev bojlera.

Spoljašnjost bojlera čistite blagim tečnim sredstvima za čišćenje. Nemojte koristiti razređivače i gruba sredstva za čišćenje.

Efikasno delovanje bez greški i dug životni vek bojlera omogućićete redovnim servisnim pregledima. Za prerđali kotao garancija važi samo ako ste redovno vršili propisane redovne preglede istrošenosti zaštitine anode. Period između pojedinačnih redovnih pregleda ne sme da bude duži od 36 meseci. Preglede mora da obavi ovlašćen serviser koji taj zahvat registruje na garantnom listu proizvoda. Kod pregleda proverava istrošenost protikorozivne zaštitne anode i po potrebi očistiće vodeni kamenac koji se, s obzirom na kvalitet, količinu i temperaturu potrošene vode, skuplja u bojleru. Servisna služba će vam na osnovu utvrđenog stanja preporučiti datum za naredu kontrolu.

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