Min. values of working pressure**
Values of min. working pressure
at the pump suction port
depending on temperature
0.8 bar at 50 °C
1.2 bar at 90 °C
1.8 bar at 110 °C
** this condition is met for current installations when the initial system pressure is set following the formula (see the Instructions for
solar collectors): p = 1,3 + 0,1·h [bar] where h… is the height from pressure gauge to the middle of collector array [m]
