 STARTING AND OPERATION

3.1. Commissioning
3.1.1. 

Before connect the appliance to power source, fi ll the tank up with mains water. To do this, turn on hot water 

mixer tap and then tap of cold water supplied to the water heater. 

3.1.2. 

Once the water heater is full, the water will fl ow from the mixer tap. Check the fl ange for leakages. Center it and 

tighten the nuts if necessary. 

3.1.3. 

Turn the hot water tap on the mixer off . 

3.1.4. 

Connect the appliance to power source.

3.2. Temperature control and activating the appliance function

Press the 

 knob to switch on the appliance. Set the desired temperature by using «+» and «-» 

knobs. Setting level is between 40°C and 80°C. During the heating phase, the LEDs corresponding 

to the temperature reached by the water so far remain lit in a fi xed manner; all subsequent LEDs (up to the set 
temperature) fl ash progressively. 
If the temperature of the water heater drops (for example after hot water has been used) the heating is reactivated 
automatically and the LEDs between the last fi xed light and the light corresponding to the set temperature will resume 
fl ashing progressively. 
The fi rst time the appliance is switched on, it will be set to a temperature of 70°C. 
In the event of a power failure or if the product is switched off  using the 

 knob, set temperature remains memorized. 

During the heating phase, a slight noise may be produced as a result of the water heating process.

Press the 

 knob to switch on the water heater. The appliance has 4 heating modes:

Manual

, 

P1

 (Programming 1), 

P2

 (Programming 2), and 

P1

+

P2

 (Programming 1 and 2) combined. 

Every time the «Mode» knob is pressed, a diff erent operating mode will be selected; the mode 

is indicated by the fl ashing of the corresponding LED on the display. Functions are selected on a cyclic basis, in 
the following order: 

P1

 (Programming 1) —> 

P2

 (Programming 2)—>

P1

+

P2

 (Programming 1 and Programming 2 

combined)—> 

Manual

 —>

P1

 (Programming 1), etc. Programs 

P1 

and 

P2

 are set by default to the 07:00 and 19:00 

time bands, and to a temperature of 70°C. 
The «

Manual» 

function (the 

«Manua

l» LED lights) allows the user to set the desired temperature simply by turning 

the «Set» knob until the desired temperature is displayed (the adjustment interval is 40°C - 80°C). If the knob is pressed, 
the setting will be stored in the appliance memory and the product will begin operating in «

Manual

» mode with these 

settings.
If the «

Manual

» function is used in conjunction with the «ECO» function, the temperature will be set automatically 

by the water heater; this means the «Set» knob will be disabled. If it is moved, «ECO» will appear on the display 
for 3 seconds. If you wish to adjust the temperature, you will have to disable the «ECO» function. The functions 
«Programming 1» («PI» LED lights), «Programming 2» («P2» LED lights) and «Programming 1 and 2» («PI +P2» LEDs 
lights) can be used to program water heating to desirable time (one or two time bands in the day). 
Press the «Mode» button until the LEDs relating to the desired program begin fl ashing to choose this function. After 
that, turn the «Set» knob to select the time band in which you would like hot water to be available (time bands are 
selected in 30-minute notches). Press the knob «Set» to store the time band setting in the appliance memory. 
Next, set the water temperature to the desired level (from 40°C to 80°C). Press «Set» knob to begin water heater 
operation in «

P1» or «P2

» mode. 

If you have selected «

P1

+

P2

», you will need to repeat the time band and temperature setting procedures for the 

second time period. Interval for which there is no set heating time will not be activated. The individual «

P1

» or «

P2

» 

programs are of equal importance and may be confi gured independently for greater fl exibility. 
When one of the programming functions («

P1

», «

P2» or «P1

+

P2

») is operated, the «Set» knob is disabled. If it is moved, 

«Pr» will appear on the display for 3 seconds. If you wish to adjust the parameters, press the «Set» knob.

If one of the programming functions («

P1» or «P2» or «P1

+

P2

») is used in conjunction with the» ECO» function, the 

temperature is set automatically by the water heater. It is therefore only possible to set the desired time band for hot 
water availability. If the «Set» knob is moved, «PLUS» will appear on the display for 3 seconds. 

Warning: 

in any setting procedure, if the user does not perform any actions for 5 seconds, the last setting will be 

stored in the appliance memory.

DOUBLE POWER function

The water heater usually operates at its basic power level. The DOUBLE POWER function activates additional heating 
element to speed up the rate of water heating. To activate it, press the 

 knob. 

To deactivate it, press the same knob 

 again.

ECO function

ECO function starts special automatic cycle of cleaning the water and the inner surface of the water heater from 
bacteria during which the optimum temperature and the rate of water heating is selected, at which most harmful 
bacteria that may be present in warm dead water are killed. 
This function should be applied if the water heater was not used more than 3 days or if you do not heat water above 
70°C. The optimum operating time of this function: 6-12 hours. For power saving, use of ECO function for more than 24 
hours at one-time switching on is not reasonable.
