OPERATION INSTRUCTIONS
1. Position Your Dehumidifier
- Install the dehumidifier horizontally to minimize vibration and or noise.
- You can adjust the feet to level the dehumidifier.
To adjust the feet
- Turn the nut in a clockwise direction to loosen the nut loosen.
- Turn the foot in a clockwise direction to get the foot down or turn the foot in a counterclockwise direction to get the foot up.
- Turn the nut counterclockwise to fix the foot.
NOTE
- For best results, operate your dehumidifiers in an enclosed area.
- Close all doors and windows that open to the outside to maximize water removal efficiency.
- Place your dehumidifier away from obstructions, and keep it away from anything that could block airflow into and out of the unit.
2. Position Your Dehumidifier
For optimal outcomes, use your dehumidifier in a confined space. Shut all entryways and windows. Position it clear of obstructions and avoid anything that could obstruct airflow in or out of the dehumidifier.
Note: Place the dehumidifier on a flat surface to minimize vibration or noise.
3. Set Up the Drainage
- Drain by Internal Pump
The dehumidifier has an internal pump that helps to drain the condensation water freely. When using the pump feature,- The Gravity Drain Outlet needs to be sealed by the included stopper.
- Connect the drain hose to the Pump Drain Outlet.
- Place the unattached end of the hose in a sink, bucket, pump sump, or out of a window anywhere that water can drain out safely. (Ensure there are no kinks or other obstructions that will stop the water from flowing.)
NOTE - If you use a bucket or other container for water collection, check it regularly to prevent overflows.
- The drain hose for the water pump can drain vertically up to 16ft. More than 16ft may cause water backup to the pump, resulting in leakage.
- If the drain hose is too long, water may not drain completely, which can lead to stagnant water and mildew buildup inside the hose.
- Before moving the dehumidifier, please remove the stopper from the Gravity Drain Outlet to completely drain the condensation in the internal water tray to avoid water leakage.
- Drain by Gravity
The collected condensation water can be drained by gravity. When using gravity to drain.- Connect the drain hose to the Gravity Drain Outlet.
- Place the unattached end of the hose to a suitable drainage facility. The drainage facility should be lower than the drain outlet of the dehumidifier. (Ensure there are no kinks or other obstructions that will stop the water from flowing.)
4. Plug in the Electrical Cord
To properly operate the dehumidifier, please plug it into a GFCl-protected 115-volt outlet with a rating of at least 16 amps. Uncoil the power cord and securely connect it to an appropriate 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 action is required.
This indicates that the dehumidifier is functioning correctly and ready to operate effectively. You will still need to press the POWER button to turn the dehumidifier on. If not operated for over 50 seconds, the control panel will become dim until pressed buttons are pressed again.
5. Understand the Control Panel
The control panel of the dehumidifier features a user-friendly interface with 4 buttons and an LED screen. Press the POWER Button to turn the dehumidifier on. After turning on the dehumidifier, the LED screen will display the readouts.
humidity percentage value. If no operations on the control panel, this number is the humidity readout of the inlet air that the dehumidifier detects, which is similar to the current room humidity level. When you are pressing the 
or 
button to set the target humidity percentage value, this digital number will turn to display the previous setting value and keep blinking.
The temperature readout of the inlet air, which the dehumidifier detects, is similar to the current room temperature.
illuminates when the timer function is enabled and disappears when the timer function is disabled.
- Fan Icon: It illuminates when the fan is running and disappears when the compressor stops running.
- Water Droplet Icon: It illuminates when the compressor is running and disappears when the compressor stops running.
Note: In the following cases, it is normal if the water droplet icon disappears, which means the compressor stops or does not kick in. - A. The humidity set-point is NOT at least 5% lower than the room humidity readout value (in this case, please double-check your setting);
- B. The room humidity level has reached the set-point, so the dehumidifier automatically stops running;
- C. The dehumidifier was just turned on and may take a few seconds for the compressor to kick in.
- D. The dehumidifier was restarted in a brief moment, and the compressor is under delay protection status.
- Defrosting icon: It illuminates when the dehumidifier detects frost on the interior. During defrosting, the fan operates while the compressor does not, and the defrost icon flashes until the frost melts. The dehumidifier will automatically begin to dehumidify, and the “Defrost” icon will disappear once the defrosting process is complete.
Note: Frequent defrosting indicates that the room temperature is too low. It is recommended to add heat when the room temperature is lower than 60°F for proper drying. - CONTINUOUS MODE: This icon illuminates when the humidity set point is 10%, which means the dehumidifier will dehumidify continuously.
- Power/Purge: Press once to turn the power on and off. Press and hold the Power button for 5 seconds to activate the Purge function (Purge function means to manually drain condensate from the pump).
- Up and Down Buttons: Press to increase or decrease the set-point of the humidity level.
- Timer Button: Press to check the settings and set the AUTO on/off timer.
6. General Operation Instructions
- Turn on the dehumidifier
- Press the Power Button to turn on the dehumidifier.
- Set a desired humidity percentage
- First of all, read the current room humidity readout on the left of the display and remember that value. Then, press the 8 or G down button to adjust the humidity set-point in increments of 1 %. The set humidity value needs to be at least 5% lower than the current room humidity readout value.
- Note: The humidity set-point is between 10% and 90%. A humidity setting between 40% and 60% is recommended for optimal comfort. Last, after selecting your target value, wait for 5 seconds for the setting to register automatically. This will ensure that your desired humidity level is set and maintained.
- Then, the dehumidifier will automatically stop and restart to maintain the room humidity level within a range of ±3% of the set point. For instance, if the set humidity is 50%, the dehumidifier automatically stops when the room humidity reaches 47% and then automatically restarts when the room humidity rises back to 53% or higher.
- Turn the dehumidifier off
- Press the Power Button to turn off the dehumidifier.
- Note: To protect the compressor, the fan will continue to operate for 30 seconds after the dehumidifier shuts off. Use the power button to stop the dehumidifier rather than forcibly disconnecting the power cord.
7. Timer Setting
It enables you to either delay the auto-on or auto-off function of the dehumidifier from 1 to 24 hours.
- Set AUTO-ON: When the dehumidifier is off, press the Timer button to set a desired time it begins to work.
- Set the dehumidifier AUTO-OFF: When the dehumidifier is on, press the Timer button to set a desired time it shuts off.

- Press the Timer Button and the Timer icon and value
, light up and flash. - Adjust the timer setting by pressing the Timer button repeatedly to change the delay timer at 1-hour increments, up to 24 hours.
- After selecting the target period, just wait for about 5 seconds to let the setting register automatically.
- The digital readout will count down the remaining time until the dehumidifier either starts or stops.
- To disable the timer function, manually turn the dehumidifier on/off, or set the timer to .
, light up and flash.Note
- Before entering the AUTO ON TIMER setting, ensure that power is being supplied to the dehumidifier.
- For the AUTO ON setting, please turn on the dehumidifier to select a desired humidity level. Otherwise, it will be the same as the previous setting.
- Set the AUTO ON timer only when the dehumidifier is off, or set an AUTO OFF timer when the dehumidifier is on, but not be able to set both the AUTO ON and the AUTO OFF timers at the same time. The AUTO ON/OFF function won’t be cycling.
- The TIMER function will be disabled when the dehumidifier is powered on/off manually.
- Set the timer, as the timer function will not be activated.
Smart Functions
- 3 Minutes Compressor Protection Mechanism
It prevents the dehumidifier from starting immediately after a complete cycle to avoid any potential damage. The compressor will start automatically after a 3-minute delay. During this time, the Fan icon is illuminated continuously on the LED screen, and until the compressor kicks in, the water droplets icon illuminates. That’s to say, if the dehumidifier is turned off and then restarted immediately, the compressor will not kick in until 3 minutes later. - Auto Defrost
The compressor cycles off when frost builds up on the evaporator coils, and the fan will continue to run until the frost disappears. Meanwhile, the DEFROST icon will light up on the LED screen during the defrosting process. - Auto-Restart
If the dehumidifier shuts off unexpectedly due to a power outage, it will restart with the previous function settings automatically when the power resumes.
