6 Putting the humidifier into operation

6.1 Start-up

Prior to starting the unit up, check the correct connections of the steam pipe, water feed pipe, drainage pipes and electrical cables.

Open the shut-off valve in the water feed pipe and switch the unit on with the black power switch.

As soon as the demand for steam is recognised, the green LED lights up, the contactor is activated and , soon after, water is let into the steam cylinder. As soon as the electrodes in the cylinder are covered with water, it is being heated and the fully automatic operation commences.

During the start-up phase, or after a new replacement cylinder has been fitted, the maximum water level can be attained. When Niveau max. has been reached, the inlet valve closes. This is a normal occurrence during the steam cylinder’s concentration phase. The length of this phase can differ, it lasts until the cylinder has reached the nominal rating. When the Niveau max. is attained it will be indicated by a red flash in the green colour of the LED.
