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.

5
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
Wet
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.

5. General Operation Instructions
(1) Turn the Dehumidifier On
Press the ON/OFF button to turn the dehumidifier on. Typically, the dehumidifier will
run in the default setting with set humidity 30%.
(2) Set a Desired Humidity Percentage Value
Press ▲or ▼button to set your desired humidity percentage value between
10%-98% in increment of 1 %. 40%-60% is a general humidity setting guide. After
selected the target value, press Timing/Function Button to confirm your setting, or let
the setting be registered automatically after 5 seconds of no operations on the control
panel.
Note:
The dehumidifier with a humidistat will stop and start automatically to maintain room
humidity level within a range of ±3% of the set point.
For example, if the set humidity is 50%,
·when the inlet humidity level the dehumidifier detects is 47%, 3% lower than the set
humidity, the dehumidifier will automatically stop and enter into "wet controller"
mode.
·when the inlet humidity level the dehumidifier detects raises to 53%, 3% higher than
the set humidity, it will automatically restart.
·However, if the set humidity level is equal to or lower than 30, the dehumidifier will
enter CONTINUOUS MODE where the dehumidifier will run continuously.
(3) Turn the Dehumidifier Off
Press the ON/OFF to turn the dehumidifier off.
Note:

8
To protect the compressor, the fan will continue to operate for 5 seconds after the
dehumidifier has shut off. So please do not disconnect the power cord to force the
dehumidifier to stop. Always use the power button.
(4) Water Drainage
During normal operation, this dehumidifier will automatically drain by the force of
gravity. If you want to move or store your dehumidifier, wait at least 10 minutes to
allow the dehumidifier to completely defrost, then lean the dehumidifier gently
towards drain to ensure that it is completely drained.
6. Timer Setting
The TIMER function enables you to either delay AUTO-ON or delay AUTO-OFF the
dehumidifier in the choice from 1 hour to 24 hours.
·Setting an AUTO-ON timer: When the dehumidifier is off, selecting Timer will turn
the dehumidifier on in the hours that will be set.
·Setting an AUTO-OFF timer: When the dehumidifier is on, selecting Timer will turn
the dehumidifier off in the hours that will be set.
Follow the below steps to set the TIMER:
·Press and hold the Timing/Function Button for about 3 seconds, until you see the
TIMER icon lights up and the small font digital number changes into 00 Hand flashes.
·Adjust the timer setting by pressing ▲or ▼button repeatedly to change the
delay timer at 1-hour increments, up to 24 hours.
·After selected the target timer value, press Timing/Function Button to confirm your
setting, or let the setting be registered automatically after 5 seconds of no operations
on the control panel.
·The small font readout will count down the time remaining (8,7,6, etc.) until the
dehumidifier either starts or stops.
·To disable the timer function, manually turn ON/OFF the dehumidifier, or set the
timer to 00 H.

Note:
·Before entering the AUTO ON TIMER setting, make sure power is being supplied to
the dehumidifier.
·For the AUTO ON setting, please turn on the dehumidifier to select a desired
humidity level.
Otherwise, the humidity maintained will be the same as the previous setting.
·You can only set AUTO ON timer when the dehumidifier is off or set AUTO OFF timer
when the dehumidifier is on, but not be able to set both AUTO ON and AUTO OFF
timer at the same time.
·The TIMER will ONLY function one time instead of cycling the dehumidifier on or off
indefinitely.
·The TIMER function will be disabled when the dehumidifier has been powered on/off
manually.
·Set the timer as 00, the timer function will not be activated.
7. Connect the Dehumidifier to an External Pump to Drain
Make sure your dehumidifier is turned off and unplugged before the
following operations:
Run the drain hose from the Gravity Drain Outlet down into the external pump (The
drain hose nor the external pump can be above the Gravity Drain Outlet).
NOTE:
·If the pump has a water full signal cable, connect it to the External Pump Terminal on
the dehumidifier, then the dehumidifier will auto stop when the pump is full to avoid
leakage. However, connecting a water full signal cable is not a must for using an
external pump to drain.
·Not all the output signal of the external pump compatible with this dehumidifier.
If the external pump output signal compatible with our dehumidifier
When the pump is full, the dehumidifier stops working and displays E5 and the

10
external pump starts to drain the water out. After the pump drained, the dehumidifier
will automatically restart.
When the dehumidifier displays an E5 error after confirming the compatibility with the
pump signal, it typically because the drain hose or the water pump is blocked. Please
turn off the dehumidifier and troubleshoot, and then restart the dehumidifier after
troubleshooting.
If the external pump output signal NOT compatible with our dehumidifier
After connecting the output signal cable to the dehumidifier, the dehumidifier does
not work and displays an E5 error and the pump does not work, which indicates the
external pump output signal is not compatible with our dehumidifier.
In this case, please disconnect the signal cable from the dehumidifier, turn off the
dehumidifier and then restart the dehumidifier. The dehumidifier will automatically
eliminate the Error code and resume working.
8. Smart Functions
(1) 3 Minutes Compressor Delay Mechanism
To avoid any damage to the dehumidifier, the dehumidifier will not start operation
following a complete cycle until after 3 minutes. Operation will automatically start
after 3 minutes. In other word, if you turn the dehumidifier off and then restart it
immediately, the compressor will not kick in until 3 minutes later. During this period,
you can see the RUNNING icon flashing on the LCD screen until the compressor kicks
in.

11
(2) Auto Defrost
When the frost builds up on the evaporator coils, the compressor will cycle off and the
fan will continue to run until the frost disappears. When the dehumidifier is defrosting,
you can see the DEFROSTING icon light up on the LCD screen.
(3) Auto-Restart
If the dehumidifier shuts off unexpectedly due to power outage, the dehumidifier will
restart with the previous function settings automatically when the power resumes.
(4) Temperature Protection Function
When the room temperature is higher than 113°F, the dehumidifier will automatically
enter into HIGH-TEMPERATURE PROTECTION SYSTEM where the LCD screen displays
an "HH" message and the compressor stops.
When the room temperature is lower than 40°F, the dehumidifier will automatically
enter into LOW-TEMPERATURE PROTECTION SYSTEM where the LCD screen displays
an "LL" message and the dehumidifier stops working.
Note: When you see HH or LL message under normal circumstances, please contact
the customer service at [e-mail] to get technical support.

MAINTENANCE
To avoid possible electric shock, ensure to turn the dehumidifier off and
disconnect the plug from the power source before performing any cleaning or
maintenance.
1. Cleaning the Dehumidifier
Clean the dehumidifier housing with a soft damp cloth. Do not submerge or place
water on the dehumidifier or control panel. Water may damage the electronic
components of the dehumidifier. Do not use chemical solvents such as benzene,
alcohol, gasoline or other heavy-duty cleaners. The surface may become damaged or
deformed.
2. Cleaning the Air Filter
The working performance of the dehumidifier will be greatly reduced if the filter
becomes blocked. The air filter should be cleaned approximately every 2 weeks and
may require more frequent cleaning if there is significant dander or fur in the air. The
air filter is located behind the inlet grill.
Follow the steps below to clean the filter:
·Unscrew the hand screw on the top of the inlet grill, open the inlet grill and take the
filter out.
·Use a vacuum cleaner with a soft brush attachment to remove any large debris or
dust build-up from the filter.
·Wash the filter in lukewarm, soapy water, below 40°C (104°F), or use a neutral
cleaning agent.
·Rinse the filter with clean water and dry thoroughly.
·Re-install the filter.
NOTE: DO NOT operate the dehumidifier without a filter because dirt and lint will clog
it, hence reducing performance.
