The Fan
The fan helps draw in and expel air from the appliance. It runs at all times while the dehumidifier is switched on, helping to distribute dehumidified air around the room. You cannot switch off the fan without stopping the appliance.
Fan Speeds
The dehumidifier fan has two speed settings: "Low" and "High." Press the "Fan Speed" button to toggle between the two speed settings. The higher fan speed increases the speed by which air is expelled from the dehumidifier into the room.
No Fan Sound
You should be able to hear the dehumidifier fan running when the appliance is switched on; an absence of fan sound may indicate a problem. Check that the dehumidifier is plugged in and switched on if there is a lack of sound. The appliance automatically shuts off when the water tank is full.
Advantages of Higher Fan Speed
A higher fan setting results in quicker moisture removal from the air. You might want to put the fan on "High" when you first switch on the dehumidifier, to help bring down the humidity to a level easily maintained on "Low."
