11.2 E. Setting valves regulating evaporative cassette irrigation flow.
Adjust the irrigation valves of the evaporative cassettes so their
surfaces are uniformly wet. The empirical value of approximately 1
litre/second for each square metre of irrigation surface is enough to
exceed the water needed for evaporation. it is necessary to ensure the
irrigation of the panels has excess water falling into the water tank.
Excess irrigation water is important to ensure constant and superficial
washing of the panels.

Remark: In the selection sheet of the HEF2 Series you will find the flow rate in L / min of each cassette.
The adjustment is done
with a flat screwdriver.
