Install the drain hose 

Attach the supplied drain hose to the draining nozzle on the appliance. Direct the hose to the desired area before operating the appliance.

  • If the drain area is located above the dehumidifier, the maximum capacity of the water pump is 16.4ft. If the water is drained downwards, there is no limit for the distance.
  • Press and hold DRAIN button to drain the water manually. The water pump will work for 20 seconds before stopping. Repeat until all water is drained. Drain the water manually before storing or moving the unit.


Do not block the drain hose. The end of the drain hose should not be higher than the outlet hole. If the end of the drain hose is higher than the outlet hole, water will not drain properly and could damage the components of the unit.




  • This unit may have been tilted or placed upside down during shipping. To ensure this device works properly, please ensure this unit is upright for at least 24 hours before initial use.
  • This dehumidifier is designed to operate with a working environment between 41°F (5°C) and 90°F (32°C).

To turn on / off the appliance 

  • Plug in the appliance, the screen will light up. Press POWER button, the unit will start working in continuous mode. The screen displays the environmental humidity. The compressor will start to work 3 seconds after the fan starts working.
  • To turn off the appliance, press POWER button, the screen displays “- -” and the appliance goes into standby mode. The fan will run for another minute before stopping.

To set the timer 

  • Press TIMER button while the appliance is off, the timer indicator will light up. Press DECREASE or INCREASE button to set the time to start the appliance. When the countdown is over, the fan and the compressor will turn on.
  • Press TIMER button while the appliance is running until the timer indicator lights up. Press DECREASE or INCREASE button to set the time to turn off the appliance. When the countdown is over, the fan and compressor will shut off.
  • To display the current temperature, press and hold TIMER button for 3 seconds. After 10 seconds, the screen will display current humidity.

To set the humidity level 

The default set humidity level is 50%RH. To increase or decrease the humidity level, press and hold DECREASE or INCREASE button. The humidity level can be increased or decreased by increments of 5%RH in normal mode.


Environmental humidity and appliance set humidity will decide the status of the compressor and fan as follow:

  • If the environmental humidity ≥ appliance set humidity+3%, the compressor and the fan will start running.
  • If the environmental humidity < appliance set humidity-3%, the compressor and the fan will stop running.

To use the continuous mode 

In continuous mode, humidity setting is invalid. The continuous mode indicator turns on and the screen will display the current humidity. To exit the continuous mode, press CONT. button. The humidity setting is resumed.

Water drainage 

  • When the water pump is full, the water pump will start automatically. The “FULL” indicator will light in red. After 30 seconds, the water pump will stop working and the “FULL” indicator will light off. Press DRAIN button to pump the water out even when it’s not full. The pump will work for 30 seconds and the “FULL” indicator will turn on and off accordingly.


  • The system has auto memory. If there is a sudden power cut during operation, the system restores the last settings before the power cut and will resume operation upon power resumption.

Defrost Function 

  1. The appliance will defrost automatically when it is operating at low temperatures. However, the compressor and the fan will shut off if the environmental temperature is below 41 °F or above 100.4 °F.
  2. After the compressor ran for 30 minutes, the temperature sensor will detect the copper pipe temperature. When the detected temperature is ≤30.2°F in the last 10 seconds, the compressor will stop and start to defrost. The fan will keep working and the defrost indicator will turn on. When the pipe temperature reaches 41°F or the defrost lasts for 15 minutes, the appliance quits the defrosting.

Note: During the defrosting, the indicator light will not be off until the defrosting is over.

Error codes 

In case of malfunction, the appliance will display an error code.

E1 – Temperature sensor fails. The system will work in cycles of dehumidification for 30 minutes and defrosting for 15 minutes. The temperature sensor needs to be replaced. Please call customer service for further support.

E2 – Humidity sensor fails. The humidity adjusting button will not work. The system will work in cycles of dehumidification for 30 minutes and defrosting for 15 minutes. The humidity sensor needs to be replaced. Please call customer service for further support.
