OVERVIEW
FISAIR HEF7 evaporative humidifiers essentially
work in accordance with the irrigation of the
evaporative panels. Humidification occurs whenever
there is an air current passing through and the water
pump irrigates the panels.
[Note] In order to eliminate superficial dust on the
panels, and to prevent its transmission to occupied
areas, the water irrigation pump should be left
operating for 6 hours with no air flow, to wash the
panels. Subsequently, the water used for washing
should be drained before normal start-up.
WATER CONNECTIONS
• Connect the water network supply to the ½” filter in Y,
and this to the solenoid supply valve.
• Connect the common outlet for the 50mm diameter
drain / overflow / constant bleed-off to the drainage
network.
• The water outlet connection to the drain must have a
water trap or seal, as shown in the figure, large enough to
overcome system pressure in order for the tank to drain
completely, for hygiene reasons. The system has the
normal slope of any drainage line.
Water trap for positive pressures
Hmin. (mm)= P(Pa)/10

Note 1: The water level should never be below the
foot of the pump water. The level below this foot of
water will damage the pump irreparably.
Note 2: It is very important that the maximum
temperature of the basin feed water does not
exceed the 25-30ºC range as the saturation
efficiency performance could be affected.
