What does it mean when my Aircare H12 displays alternating “F” and room humidity?

If your Aircare Humidifier is displaying alternating “F” and room humidity, it means the reservoir is empty, and the float isn't activating the switch on the chassis. Fill the humidifier with water and reposition the chassis so that the float and switch are aligned.
