Locate the "+" and "-" (plus and minus) humidity control keys on the dehumidifier's control panel.
Press the "+" or "-" keys until the desired humidity level is indicated on the control panel display. Note that most manufacturers recommend setting the humidity between 35 and 75 percent for normal operation.
Specify how long you want the current humidity control setting to run. Press the "Timer" button to toggle between the "2-Hour" and "4-Hour" options. Indicator lights directly above the "Timer" button show which option is currently selected.
- Adjust the fan speed for your dehumidifier, if desired. Press the "Fan Speed" button to toggle between the "Low" and "High" fan speed settings.
