power on, open the hot water valve for approx. 20 seconds in order to remove air bubbles
from the system. Then, turn the power on. Open the hot water valve waiting till the device has
achieved full operational readiness (approx. 5 seconds) beginning the process of heating – in
the lower part of display lines will be shown indicating (in percent) the heating power of the
heater. Close the hot water valve. The heating process is automatically turned off – the lines
previously indicating the heating power will disappear from the display.
