Note: Most water does not contain enough conductivity for full boil on initial start-up. Units

will need to concentrate the water over a time period (hours to days). It is normal for
the humidifier status to cycle between “Filling” and “Warning – Max Level” indicating
water level is at the top of the cylinder during this time period.
