gorenje GT 5-15 Electric Water Heater
WARNINGS
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 provide.
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.

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
OPERATION AND MAINTENANCE
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 ” ***** ” 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 °С
B: 45 °С
A: 55 °С
O: 75 °С
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.
