  • Manual & FAQs

    Question: What do I do if the nightlight on my unit isn’t lighting up?

    Answer: Make sure the light button is pressed to turn on the color changing light.  Press a second time to stop on the current color. 

    Question: Why is there condensation on my walls, ceiling, windows, etc.? 

    Answer: If there's condensation, then the humidity level in the room or the house is too high, and the air is becoming saturated with water. We recommend waiting to use the unit until the moisture level drops or using the unit on a low setting. A hygrometer can be helpful in determining the actual room humidity.
