『SAFETY INFORMATION』
To prevent injury to the user or other people and property damage, the following instructions
must be followed when using the dehumidifier.

support it when the water bucket is full.
2. Do not place the dehumidifier near a heater.
3. Do not use the dehumidifier near flammable gas or combustibles, such as gasoline, benzene,
thinner, etc.
4. Always plug into a grounded outlet properly.
5. Do not use if the power cord is broken or damaged.
6. Do not use the socket if it is loose or damaged.

『CONTROL PANEL IDENTIFICATIONS』
1. Understand the Top Control Panel
The top control panel features a digital display and 6 buttons.
1) Understand the Control Buttons
POWER Button: Press to turn the dehumidifier ON or OFF.
Mode Button: Press to switch the working mode between DH (DEHUMIDIFY) mode and DRY
(Laundry Dry) mode.

4
HUMIDITY Button: Press the HUMIDITY button repeatedly to adjust the set-point of humidity level
between 30%-80% (in 5% increments) during normal DEHUMIDIFY (DH) mode. The digital number
on the display will flash when changes are being made.
NOTE: The HUMIDITY button will be disabled in the DRY-CLOTHES (DRY) mode.
SPEED Button: Press the SPEED button to set the fan speed to FAST or SLOW in the normal
DEHUMIDIFY (DH) mode.
NOTE: The SPEED button will be disabled in the DRY-CLOTHES (DRY) mode.
TIMER Button: Use this TIMER button to set an AOTU-ON or AUTO-OFF timer, between 1-24 hrs.
When timer function is enabled, the system will countdown the time remaining and you can check
the time remaining by pressing the TIMER button once.
LIGHTING Button: Press the LIGHTING button to send the display to sleep status where the digital
display and the backlight of the buttons other than the POWER button and the LIGHTING button will
go off and these buttons will be disabled, while the dehumidifier maintains running status. The
indicator light above the LIGHTING button will light up in this case. Press the LIGHTING button again
to restore the backlight and functions of these buttons.
NOTE: Press and hold the SPEED button for 3-5 seconds, the LCD will show the room temperature
readout in Fahrenheit. 5 seconds later, the LCD will turn back to display the room humidity readout.
2) Understand the LCD Display
The BIG FONT Digital Number is humidity reading. If no operations on the control panel, the
number is the humidity percentage readout of the inlet air the dehumidifier detects which is similar
to the room humidity level. When you are pressing the HUMIDITY button to set the target humidity
percentage value, the digital number will turn to display the setting value and flash.
FULL: The “Full”icon will light up when the bucket is full of water, as a reminder to empty the water
bucket. Empty the bucket and re-install the bucket properly to resume regular functioning.
FAST: The “FAST”icon will light up when the FAN speed was set to high.
SLOW: The “SLOW”icon will light up when the FAN speed was set to low.
DRY: The “DRY”icon will light up when the DRY-CLOTHES mode has been selected.

5
DH: The “DH”icon will light up when the normal DEHUMIDIFY mode has been selected.
2. Understand the Front Display
The front display displays the same content, like humidity readout or error codes, as the digital
display on the top control panel. So you can read the room humidity level on the front display easily,
in a visible distance.
『OPERATION INSTRUACTIONS』
1. Position Your Dehumidifier
·Place the dehumidifier on a smooth, level floor that is strong enough to support the dehumidifier
with a full bucket of water.
·To maintain efficiency, operate the dehumidifier in
an enclosed area. Keep nearby doors and windows
closed.
·Maintain a minimum clearance of 20 cm
(7.9 inches) on the sides and back of the dehumidifier
and 40 cm (16 inches) on the top
of the dehumidifier to allow for proper
air circulation.
·To use the dehumidifier to dry wet clothes,
maintain a minimum clearance of 40 cm
(16 inches) to the air outlet of the dehumidifier to
avoid water dripping into the dehumidifier.
·The recommended ambient operating temperature
is between 5°C (41°F) and 35°C (95°F).
2. Plug in
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
Uncoil the power cord and plug it firmly into a properly grounded 110-120 volt AC outlet.
After plugged in, the control panel will be light up for 1-2 seconds and then goes off, which is the
normal self-diagnose process and does not require any user intervention.
3. Turn the Dehumidifier On
Press the POWER button to turn the dehumidifier on. Typically, the dehumidifier will run in the
default setting of 30% set humidity at low fan speed in the normal DEHUMIDIFY mode.
NOTE: If the dehumidifier does not run automatically and you see the “FULL”icon illuminate, please
remove the water bucket and re-install it properly.
4. Select Working Mode
1) DH (DEHUMIDIFY) Mode
In the DH (DEHUMIDIFY) mode, the dehumidifier will automatically stop and restart based on the
humidity setting, which is called Humidstat Mode, hence maintaining the room humidity within the
range of ±3% of the set point.
For example, the set humidity is 50%, the dehumidifier will automatically stop working when the
room humidity reaches 47%, and then automatically restart when the room humidity raises up to
53%.
NOTE:
When the set humidity level is not at least 3% lower than the room humidity level, the dehumidifier
won’t start, and DH icon will flash.
When the room humidity level has been dropped down to the set-point, the dehumidifier will auto
stop dehumidifying and the DH icon will flash.
If you set the target humidity at 30%, the dehumidifier will run continuously until the water bucket
is full, which is called CONTINUOUS Mode.
To run the dehumidifier in the normal DEHUMIDIFY mode:
·Select Mode: Press the MODE button until you see the “DH”icon light up on the display to select
the normal DEHUMIDIFY mode.
·Check the Room Humidity: when no operation on the control panel, the digital number on the
display is the humidity readout of the inlet air, which is similar to the room humidity level.
·Set Your Desired Humidity: After selecting DEHUMIDIFY mode, press the HUMIDITY button
repeatedly to adjust the set-point of humidity level between 30%-80% in 5% increments. The digital
number will flash when changes are being made. The set humidity needs to be at least 5% lower
than the room humidity. After you have selected the desired value, please wait for 5 seconds until
