1.6 FILLING OF THE INSTALLATION
The electric heating unit is provided with a ball valve to ll the
heating installation up to 1 - 3 bars. During operation, in case
the pressure decreases in the system (because the air is remo-
ved from the system) to the minimum value of the above men-
tioned pressure, open the ll valve to supplement with water.
Turn the ll valve anticlockwise to supplement with water and
clockwise to close it. The electric heating unit operates usually
at 1-1,5 bars. After lling, close the ll valve (“g. 4 - Water
lling valve”).
