Page 26: Setting The Valve Regulating Irrigation Flow
HEF7 series manual 26 13. Setting the valve regulating irrigation flow Set the valve for the irrigation of the panels to ensure uniform watering of the surface area of the panels. A value of around 1 liter/second for each square meter of irrigation surface is enough to exceed the water required for evaporation. -
Page 27: Setting The Valve Regulating The Bleed-Off Flow
HEF7 series manual 27 Setting the valve regulating the bleed-off flow Water evaporation is caused by a higher water vapour pressure in the evaporative panel than in the air moving across it. Because only the water evaporates, dissolved mineral salts remain in solution, and gradually increase in concentration, despite new water being added to compensate for the evaporation. - Page 28 HEF7 series manual 28 Set the flow of the bleed-off valve by removing the handwheel from its parked position and placing it on the flow meter. It can then be swivelled to set the required flow. Once the flow has been set, place the handwheel in its parked position once again.

Page 29: Start-Up Recommendations
(application in English) The operation of the FISAIR HEF7 Series evaporative humidifier is mainly determined by the irrigation of the evaporative panels. The humidifier will work as such whenever there is a current of air passing through it and the water pump irrigates the panels. -
