8. Working principle

The humidifier washes the boiler and the hydraulic system completely, removing all the limestone,
to avoid air pollution coming from water, which remained too long in the boiler.
At the same time, the electronic card tests the entire system: water drain, water feeder. It points
out eventual troubles with lights.
If the water change procedure in the boiler is not correct within 5 minutes, the machine stops the
attempt automatically, switches on the failure led but it starts the steam production regularly.
The water input for the production is normally enough to start a minimum production. Then, the
humidifier feeds the water in small quantities between long intervals, until the production reaches
the humidistat's demand.
The humidifier drains completely the hydraulic system every 2 hours of full production or in case of
salt concentration in the boiler too high.
The water's drain uses patented double syphon system to avoid the use of solenoid and enabling to
remove big bit of limestone.
The boiler has also a simple but effective valve which allows the steam passage to the output, but
it stops the water and gives enough pressure at the boiler to eject big pieces of limestone.
