from the move, not doing so can affect the performance or lifespan of the
dehumidifier.

counterclockwise direction to get the foot up;
·Turn the nut in a counterclockwise direction to fix the foot.
NOTE:
·For best results, operate your dehumidifiers in an enclosed area.

(Ensure there are no kinks or other obstructions that will stop the water to flow.)
3. Plug in
·Uncoil the power cord and plug it firmly into a properly grounded 110-120 volt AC
outlet.
·After plugged in, the control panel will light up for 1-2 seconds and then goes off,
which is the normal self-diagnose process and does not require any user intervention.
4. Understand the Control Panel
The control panel on the dehumidifier has an LCD screen and 4 buttons. Press the
ON/OFF Button to turn the dehumidifier on. The LCD screen will light up and display
the readouts as below.
IMPORTANT
Please let the dehumidifier sit outside the box for 24 hours before initial plugging in.

What is on the LCD Screen?
Big Font Digital Number (43 RH% on the above illustration) is humidity percentage
reading of the inlet air that the dehumidifier detects which is similar to the room
humidity level. When you are pressing the ▲or ▼button to set a desired humidity
percentage value, the big font digital number will turn to display the setting value and
flash.
Small Font Digital Number (77°F on the above illustration) is temperature reading of
the inlet air which is similar to the room temperature. However, if the timer function is
being set or has been activated, the small font digital number will turn to display the
timer setting value or time remaining.
Running Icon：Running icon flickers typically because the compressor has not
kicked in. It usually happens ①when the dehumidifier is under the 3-minute
compressor delay status; ②when the dehumidifier is programmed to delay-start
(AUTO ON TIMER).
Wet Controller Icon: Wet Controller Icon flickers when the room humidity level
Running

Controller

6
(inlet humidity reading) is 3% lower than the set humidity.
When you see the "wet controller" icon illuminating while setting up, it typically means
the set humidity level is not 3% lower than the inlet humidity reading. Please make
sure the set humidity value is at least 3% (10% recommended) lower than the inlet
humidity reading.
In Humidistat Mode, if you see "wet controller" icon illuminating after running the
dehumidifier for a while, it means the dehumidifier has got the room humidity down
to the set point and the dehumidifier enters into standby mode.
Defrosting Icon: The dehumidifier begins to defrost when the frost has
accumulated on the interior of the dehumidifier. When the dehumidifier is defrosting,
the fan is running, but the compressor is not, the defrost icon is flashing. The
dehumidifying function will cease until the frost has melted. When defrosting is
complete, the defrosting Icon will disappear and the dehumidifier begins to
dehumidify again automatically.
Note: The frequent defrost process indicates that the room temperature is too cold.
Therefore, if the room temperature is lower than 60°F, please consider adding heat to
promote proper drying.
Fan Icon: The fan icon illuminates when the fan is running.
Water Droplets Icon: The water droplets icon illuminates when the compressor
kicks in, which means the dehumidifier is dehumidifying. When the compressor delays
to start due to the 3-minutes delay system, this icon flickers.
Timer Icon: Timer icon illuminates when the timer function is enabled.
Understand the Control Buttons
ON/OFF Button: Press to turn the dehumidifier ON or OFF.
