• “” lights up when the dehumidifier has been plugged in but not turned on yet.
• “” shows the current room humidity. When you press the”” or “” button to set the target humidity, it will turn to display the previous setting value and keep blinking.
• ““lights up when the fan is running and lights off when it stops running.
• ““Flickers typically because the compressor is not kicked in. It usually happens when the dehumidifier is under the 3-minute compressor delay status, or the dehumidifier is programmed to delay-start (AUTO ON TIMER).
• “” lights up when the setting humidity is 10%, and the dehumidifier enters into continuous mode.
• “” flashes when the dehumidifier is defrosting. The dehumidifier will defrost when frost accumulates on the interior of the dehumidifier. The fan keeps running when defrosting, while the compressor is not. The dehumidifying function will cease until the frost melts. “” will light off when the defrosting is completed, then the dehumidifier begins to dehumidify automatically.

NOTE: Frequent defrost process indicates that the room temperature is too low. Therefore, if the room temperature is lower than 60°F, please consider adding heat to promote proper drying.

““Lights up when the pump is in good condition. It will light up once you turn on the dehumidifier. It flashes when the pump is working to drain the water out.

“” and “” will blink when the ambient humidity value is lower than or equal to the preset humidity value. After 30 seconds, the compressor and fan stop working. The dehumidifier will automatically restart when the ambient humidity exceeds the preset value.

Setting

Power

Press the “power” button to turn the dehumidifier on. When the dehumidifier is on, the “” indicator lights off, and the “” indicator lights up.

Check the Room Humidity

Check the room humidity readout (““) on the control panel.

Set a Desired Humidity Percentage Value

Press the “” or “” button to preset your desired humidity level. The humidity level can be set within a range of 10%RH(Relative Humidity) to 90%RH(Relative Humidity) in 1%RH increments. The setting humidity needs to be at least 5% lower than the room humidity. After setting the target humidity, press “” or wait 5 seconds to confirm.

NOTE:

• The dehumidifier will stop and start automatically to maintain the room humidity level within a range of ±5% of the preset target humidity.

For example, if the set humidity is 50%:

When the detected humidity is 45%, 5% lower than the preset humidity, the dehumidifier will automatically stop and enter into standby mode, the compressor stops working, and the indicators “” and “” flash.

When detected humidity rises to 55%, 5% higher than the preset humidity, the dehumidifier will automatically restart.

• If the preset humidity is equal to or higher than the room humidity, the dehumidifier will not start.
• If the preset humidity level is 10%, the dehumidifier will enter continuous mode and run continuously.

Timer Setting

The “” function enables you to either delay AUTO-ON or delay AUTO-OFF the dehumidifier in the range from 1 hour to 24 hours. Press “” and “” to adjust the timer by 1-hour increments.

• Setting AUTO-ON timer: When the dehumidifier is off, press “” to set a timer to automatically start the machine.
• Setting AUTO-OFF timer: When the dehumidifier is on, press “” to set a timer to automatically shut down the machine.

NOTE:

1. Before setting the AUTO-ON TIMER, make sure the dehumidifier is plugged in.
2. For the AUTO-ON setting, please turn on the dehumidifier to set a desired humidity level. Otherwise, it will maintain the previous setting of humidity.
3. You can only set the AUTO-ON timer when the dehumidifier is off, or set the AUTO-OFF timer when the machine is on. It is not able to set both AUTO-ON and AUTO-OFF timers at the same time.
4. The timer will ONLY function one time instead of cycling the dehumidifier on or off indefinitely.
5. The timer function will be disabled when the dehumidifier has been powered on/off manually.
6. Set the timer to 00, and the timer function will not be activated.

Drainage Setting

During operation, it will automatically pump the water out via the drain hose when the pump reservoir is full. No need for manual intervention.

Before moving the dehumidifier, press “” to empty the pump reservoir to avoid water spillage.

“” will blink when the pump is draining. The pump will stop working automatically in 40 seconds and stop blinking when the pump reservoir is almost empty.

NOTE: Please press “” to empty the built-in reservoir first to avoid water leakage while moving the dehumidifier.

Turn the Dehumidifier off

Press “power” to turn the dehumidifier off. When the machine is turned off, the “” indicator lights up, and the “” indicator lights off.

NOTE: To protect the compressor, the fan will continue to operate for 5 seconds after the dehumidifier shuts off. So, please do not disconnect the power cord to force the dehumidifier to stop. Always use the “power” button.

Smart Functions

3 Minutes Compressor Delay Mechanism

To avoid any damage to the dehumidifier, the unit will not start working in a 3-minute complete cycle. In other words, 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 “” indicator flashing on the LCD screen until the compressor kicks in.

Auto Defrost

When the frost builds up on the evaporator coils, the compressor will stop working, and the fan will continue to run until the frost melts. When the dehumidifier is defrosting, you can see the “” indicator light up on the LCD screen.

Auto Drainage

Thanks to the built-in pump, the dehumidifier will drain the condensation water automatically.

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.

The timer function will not be retained, and you need to reset it.

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 shows “-H” and the compressor stops working.

When the room temperature is lower than 40° F, the dehumidifier will automatically enter into LOW-TEMPERATURE PROTECTION SYSTEM, where the LCD screen shows “-L” and the dehumidifier stops working.

Drainage

Pump Drainage

During operation, the dehumidifier will automatically pump the water out via the drain hose when the pump reservoir is full. No need for manual intervention.

Before turning on the dehumidifier, make sure the hose has been connected to the drain outlet properly.

NOTE:

Place the unattached end in a sink, drain, bucket, or outdoors – anywhere that water can drain out safely. (Ensure there are no kinks or other obstructions that will stop the water from flowing.)

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 up to 15ft vertically. More than 15ft may cause water flow back to the pump and result in water leakage.

Continuous Drainage

NOTE:

1. Please make sure the connections are securely connected to avoid water leakage.
2. The hose should be lower than the drain outlet to avoid backflow.
3. The hose cannot be distorted or have substantial twisting.

Maintenance

WARNING:

Ensure the dehumidifier is turned OFF and unplugged before cleaning or maintenance.

Machine Cleaning

Wipe 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 machine.
