Start Your Job
Turn on the dehumidifier
Press the Power Control button to switch on the machine. You may see the
dehumidification light is flashing. Please wait for 3 minutes (180 seconds) until the
machine completes the startup.
Write down the starting time
Please remember to write down the starting time right after the machine
starts, if you want to calculate the usage time.
Set the desired humidity level
• Tap the humidity control button to adjust the setting humidity level. The default
humidity setting is 30%. The adjustable range is from 30% to 90% (See Page 7:
Humidity Control). The machine will try to match the set humidity level and maintain it.
• If you want the machine to work constantly, please adjust the humidity level down
to 30%, and then press “-” (See Page 8: Constant Dehumidification). Tap “+” to exit
constant dehumidification mode.
• If the dehumidifier loses power accidentally, when turned on again, the dehumidifier
will work on the last known configuration.
Dehumidification
• When the machine is dehumidifying, the dehumidification light goes on.
• You may see the dehumidification light is flashing. That means the dehumidification
temporally pauses or the environmental humidity has reached the setting level. Please
wait until the machine completes the startup or until the humidity level rises up again.
• The dehumidifier will control the fan speed according to the environmental temperature
and humidity.
Defrosting
• When the evaporator coil or the environmental temperature is too low, frost may
appear on the evaporator. This will lower the effectiveness of the dehumidification. The
machine will start defrosting until the temperature goes back to normal.
• When the machine is defrosting, the dehumidification pauses. The dehumidification
light goes off, and the defrosting light will go on.
• Do not turn off the machine during defrosting process.
