MAINTENANCE
The best way to determine how often the humidifier needs maintenance is to remove the steam chamber and inspect it after the first
year of operation. Potable water carries a variety of minerals and other materials in a mix that varies from location to location. This
variation in water quality, combined with the hours of operation and duty cycle, determines the frequency maintenance required.
