NOTE
: Most water does not contain enough conductivity for full boil on initial startup and after new cylinder replacement.
Units will need to concentrate the water over a time period (up to 24 hours). It’s normal for the humidi

er status to cycle
between “Filling” and “High Water” (max water level) during this time period.
