CONNECTION TO THE WATER SUPPLY
The water heater connections for the in-flowing and out-flowing water are colour-coded. The
connection for the supply of cold water is coloured blue, while the hot water outlet is coloured
red.
The water heater may 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 purchased 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 an instantaneous 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 return 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. 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
the 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 located in the 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 return
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 relief valve, periodical inspections of the relief
valve must be carried out by the user. To check the valve, you should open the outlet of the
return 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.

5 - Closing valve
H - Cold water
T - Hot water
Between the water heater and return safety valve no closing valve may be built-in
because with it the function of return safety valve would be impeded.
The water heater may be connected to the water network in the house without reduction
valve if the pressure in the network is lower than 0.5 MPa (5 bar). If the pressure exceeds
0.5 MPa (5 bar), a reduction valve must be installed. Prior to the electric connection the
water heater must obligatorily be filled with water. By first filling the tap for the hot water upon
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.
CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK
Before connecting to power supply network, install a power supply cord in the water heater,
with a min. diameter of 1,5 mm2 (H05VV-F 3G 1,5 mm2). For it the protection plate must be
removed from the water heater.
The connection of water heater to the electric network must be performed according to
standards for electric installation. Install a disconnect switch (separating all poles from the
power supply network) between the water heater and the permanent power connection, in
compliance with the national regulations.

Manual temperature setting:
- Use the key and select the operating mode (yellow control lamp under is on).
- The display always shows the last setting of the water temperature; except on first turn on
of appliance when factory setting 35ºC is displayed.
- Use the or key to select new temperature. By pressing the key you increase/
decrease the temperature by 1ºC. Holding the key will speed up the process.
- After required temperature is set display flashes for 3 seconds and then shows the current
temperature again.
- In case of interruptions in power supply, the appliance resumes operating with the settings
adjusted before the interruption.
INDICATION:
• Control lamps:
- Heating element operation : Green control lamp:
- the heating element is on – the lamp is on
- the heating element is off – the lamp is off
- Mg anode : Red control lamp:
- the lamp is off – anode is active
- the lamp is on – anode may be worn out
Warning! When the water heater is out of use for longer
period of time, the signal lamp may indicate that the

Freezing protection:
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.
Discharging water from the water heater:
Water is discharged from heater via the inlet pipe. To 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 same position as for checking the operation. Before discharge, make
sure the heater is disconnected from the power supply, 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
MAINTENANCE
The external parts of the water heater may 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 authorized
maintenance service provider about two 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 product 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 authorized service provider.
