TROUBLESHOOTING
Q: I hear the fan turning, but I don't see any mist. Is my humidifier operating properly?
A: Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no " mist" emitted. When
operating normally you will feel only cool air coming from the unit. Monitor the water level in your Tank/ Base. If you notice
a decrease in the Water Tank over 24 hours then the unit is operating normally.
Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the
tank decreasing.
A: Check the water window to see if water is flowing through the system. If the water window does not show any water flowing,
then remove the housing and check the silver screen located on the bottom of the pump to ensure the screen is not blocked.
Also please note, if the humidity level in your home is above 60%, you air is fully saturated and the humidifier will be unable
to put out additional moisture.
Q: The humidifier is not running (the fan is not even spinning), but all (or some) of the lights are on.
A: The water window will change from blue to green when your desired humidity is reached. The unit will then shut off until the
room humidity drops below the preset level or you change the control to a higher humidity setting.
Q: The Advanced Mist™ Humidistat knob was set according to the manual, but the humidifier never seems to turn
back on. Is something wrong?
A: The Humidistat knob may be set too low. Moving the Humidistat knob to the end clockwise
Q: The Advanced Mist™ Humidistat knob was set according to the manual, but the humidifier never seems to turn
off. Is something wrong?
A: The Humidistat knob may be set too high. Reset the Advanced Mist™ Humidistat knob following the instructions under
FEATURES.
Q: My filter has turned light brown and rust colored or has a lot of scaling. Do I need to clean my filter?
A: Probably not. Since your filter has been made with Protec™ antimicrobial the change in color indicates only a mineral
deposit. Soak filter in a sink full of cool water to help break up deposits. The discoloration may remain but will not affect
the humidifier's performance. Your filter should however be cleaned every 1-3 months depending on usage to keep your
humidifier operating properly
Q: My humidifier doesn't appear to be as clean as when I first purchased and/or I'm smelling an unpleasant odor.
What should I do?
A: If you have been using your humidifier regularly for over 30 days, follow the cleaning instructions.
Q: Unit is running but I do not see any visible water movement in my water window.
A: Check to be sure your unit is not out of water. Also check to make sure the pump inlet screen is not clogged.
Q: My unit makes a gurgling sound.
A: When the unit first starts up, there may be air that is sucked into the system which can produce this sound. Please allow 15 to
30 minutes for this to go away.
