OPERATION INSTRUACTIONS
1. Install the Handle
1) Unscrew the pre-installed hand screws on both sides of the handle to take the handle
off.
2) Install the handle as illustrated below, please note to align the holes on the handle with
the holes on the dehumidifier.
3) Tighten the 4 hand screws securely until the handles secure tightly against the
dehumidifier.

4
2. Position Your Dehumidifier
For best results, operate your dehumidifiers in an enclosed area. Close all doors and
windows. Place your dehumidifier away from obstructions, and keep it away from anything
that could block airflow into and out of the dehumidifier.
3. Set Up the Drainage
Attaching the included drain hose to the drain outlet on the right side of the dehumidifier
to drain the condensation water automatically by gravity.
NOTE: You can use any other hoses with inner diameter of 5/8 (0.63) inches instead.
Unwind the hose and then direct the other end of the hose down to a suitable drainage
facility, like a bigger external bucket or floor drain. The drainage facility should be lower
than the drain outlet of the dehumidifier. Make sure the hose has no kinks and is
unobstructed, so the water can be drained smoothly by gravity.

4. Plug in Electrical Cord
The dehumidifier needs to be plugged into a GFCI-protected 115 volt outlet rated for at
least 16 amps. Uncoil the power cord and plug it firmly into a suitable outlet.
Note: When the dehumidifier is first plugged into AC power, the control panel display will
light up for a second, which is part of the dehumidifier’s self-diagnosis procedure and no
user intervention is required.
5. Understand the Control Panel
The control panel on the dehumidifier has an LCD screen and 4 buttons. Press the POWER
Button to turn the dehumidifier on. The LCD screen will light up and display the readouts.
(1) What is on the LCD Screen?
Big Font Digital Number (43 on the above illustration) is humidity reading. If no operations
on the control panel, this big font digital number is the humidity reading of the inlet air 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 (34 on the above illustration) is temperature reading of the
IMPORTANT
Please let the dehumidifier stand upright for 24 hours before the first time plugging in.
The dehumidifiers may have been tilted or placed upside down during shipping. Leave the
dehumidifier to stand upright for 24 hours so the oil in the compressor can settle from the
move, not doing so can affect the performance or lifespan of the dehumidifier.

6
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 1) when the dehumidifier is under the 3-minute compressor delay status; 2)
when the dehumidifier is programmed to delay-start (AUTO ON TIMER).
Wet Controller Icon: Wet Controller Icon flickers when the room humidity level (inlet
humidity reading) is 3% lower than the set humidity.
1) 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.
2) 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. When the room humidity
level raises up to 3% higher than the set humidity, the dehumidifier will automatically
restart to dehumidify. That is to say, the dehumidifier will automatically stop or restart to
maintain the 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.
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.

7
Timer Icon: Timer icon illuminates when the timer function is enabled.
(2) Understand the Control Buttons
Power Switch: Press to turn the dehumidifier ON or OFF.
Up Button: Press ⬆to increase the set-point of humidity level or timer.
Down Button: Press ⬇to decrease the set-point of humidity level or timer.
Timing/Function Button: Press once to check the settings. Press and hold for 3 seconds to
enter Timer setting system.
6. General Operation Instructions
(1) Turn the dehumidifier on
Press the Power Switch to turn the dehumidifier on.
(2) Set a desired humidity percentage value
Press ⬆or ⬇button to set your desired humidity percentage value between 1%-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 the inlet
humidity level the user has set. 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 Power Switch to turn the dehumidifier off.
Note: 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.
7. Timer Setting

dehumidifier either starts or stops.
5) To disable the timer function, manually turn ON/OFF the dehumidifier, or set the timer
to 00.
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 feature is one-shot. So 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.
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.
(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.
