When starting the unit with the cylinder empty, a significant period must pass (which depends greatly on the conductivity of
the supply water and may even be a few hours long) before the rated production is reached. In fact, to achieve a level of
current sufficient to produce the rated thermal power, the salinity and thus the conductivity of the water must reach a
sufficient level through the repeated evaporation and water filling. This obviously does not occur if the machine is started
with cylinder containing water that already has a sufficient level of conductivity.

After having closed the disconnecting switch on the humidifier power
supply line, turn the appliance on by placing the rocker switch in
position

(see Fig. 6.2.1.2).
The start-up sequence is thus initiated, which includes an initial phase
followed by the actual operating phase.
The start-up sequence is highlighted by the illumination of the LEDs on
the control panel, as described in
