Use
Setting the water temperature is done by pressing one of the buttons located under the
display marked with “–” or “+” signs (pict. 1) in the range from 30
O
C to 60
O
C.
Detecting by the heating system bigger flow than the 2.9 l/min will result in switching it on
what is signalled with brighter lighting of the display. The drop of the flow below the point of
turning on will result in turning off signalled with decreasing of the brightness of the display.
When the water flow through the heater is too strong in relation to the set temperature, the
display will signal it displaying the “–” signs alternatively with the set heating temperature.
In case when the inlet temperature exceeds 40
O
C, the heater will turn off to the moment
when the feedwater temperature drops below 46

C.

Efficiency of warm water depends on the temperature of inlet water.
Cleaning the water filter
In a situation when the filter is partially or fully blocked, follow the steps:
1. Disconnect the power supply
2. Unscrew the fastening screw located at the bottom of the casing (pict. 1), then take the
casing off holding it in such a distance from the heater so that the belt cable connecting
the display with the heater was not stretched, and then disconnect the cable by taking
out the plug from the socket marked “DISPLAY” (pict. 2).
3. Close the control valve (marked 1).
4. Open the plug of the control valve (marked 2).
5. Take out mesh filter (marked 3).
6. Remove dirt
7. Insert mesh filter
8. Close the valve plug.
9. Open the flow on the control valve and check the watertightness of connections.
10. Connect the belt cable to the display plate (pict. 2).
11. Close the casing
12. Perform the air relief of the heater, and then start it according to chapter “Start-up”.
