Setting Humidity
The humidity level can be set within a range of 30%RH to 80%RH in 5% increments.
When it starts work, it will first automatically detect and show the room's humidity. Press the “UP” button to change the humidity selection in 5% increments. “88” will flash and show the setting humidity.
Press “UP” to increase the humidity by 5%RH.
Press “DOWN” to decrease the humidity by 5%RH. After 5 seconds of no operation, “88” will show the actual room humidity.
When the humidity level is higher or drops to the level you have set, the dehumidifier will automatically begin to work or stop.
When the humidity level is set at 30%RH, the dehumidifier will work in continuous dehumidifying mode.
Timer Setting
This TIMER setting function is designed for you to set a time to turn off or turn on the machine, automatically by the timer.
Press the “TIMER” button to select the timer by 1-hour increment. You can set the timer up to 24 hours. It will start to count down when you start the timer.
Press and hold the “TIMER” button for several seconds to make the selection of the timer faster.
If the time is set to 00, this is called the invalid time. If you set the timer successfully, the light (? or ⏰) will be up. The LED screen will show the remaining time if you press the “TIMER” button, and display the current humidity automatically after a few seconds.
Speed Button
Control the fan speed. Press to select either High or Normal fan speed. Higher fan speed will result in quicker moisture removal. Set the speed high for maximum moisture removal. When the humidity has been reduced and quiet operation is more preferred, set the fan speed back to Normal.
Light Function Setting
In the power-on state, press the “Light” button to turn on or turn off the backlight.
When the light function is powered on, except the “Power” button and the “Lighting” button, other backlight indicators will be off.
LOCK (2S)
When the unit is turned on, press “LOCK” and hold for 2 seconds; the control panel will be locked along with the other buttons. To unlock the control panel, press and hold the “LOCK” button again for 2 seconds.
Power Off Memory Function
The device automatically restores the working state after power on.
If the device is turned on and a power interruption occurred, after starting the unit again, it will keep the previous parameters of setup.
If the device is turned off and power interruption occurred, the device will still be in a power-off status when turned on.
Overflow Protection
When the water tank is full of water, the machine will turn off automatically. The indicator light (WATER FULL ? or WATER FULL ?) will flash. After you empty the water from the tank, the indicator light (WATER FULL ? or WATER FULL ?) will turn off. The machine will restart to work.
Caution: Water tank must be placed in the right position, otherwise, it will cause the water full alarm.
Auto Defrost Feature
When the dehumidifier is running at a lower temperature, the system will automatically determine whether there is a presence of frost. If any frost exists, it will defrost automatically.
Defrost Action
The fan runs at high wind speed when the compressor stops, and the LED screen displays the defrosting symbol.
3. Display Status Description
When the device is currently powered on, before any operation, only the “POWER” light will be up, indicating the device is in “Standby” Status.
Setting light (? or ⏰): If the timer is set up properly, the indicator light will be up. It will flash if the TIMER button is pressed again to check and reset, and go out if the setup is unsuccessful.
Lighting button (?): If the lighting function is powered on, the light button will be on, but other backlight indicators will be off.
High-speed indicator light (FAST ?): If you set the unit to high-speed fan mode, this indicator will light up.
Low-speed indicator light (SLOW ?): If you set the unit to low-speed fan mode, this indicator will light up.
Dehumidification light (DEHUMIDIFY ?): When the machine starts to dehumidify, the indicator light will be on.
Water full indicator light (WATER FULL ? or WATER FULL ?): When the water tank is full, this indicator will be flashing.
LOCK indicator light (?): The indicator will light up if the control panel is locked successfully; otherwise, the indicator will not be on.
When the dehumidifier normally works, “88” will show the current humidity.
4. Instructions for Drying Clothes
The dehumidifier can be used for drying clothes in rainy weather.
Step 1:
Hang the washed clothes in a small space such as a cloakroom, bathroom, or storage room. Note: Keep the unit away from the water drips of the washed clothes.
Step 2:
Open the dehumidifier and set the humidity level at 30%RH. It's best if you let the air outlet of the dehumidifier blow air to the clothes directly.
The drying effect will vary from the thickness of clothes, the number of clothes, and the size of the drying space. Theoretically, the effect will be better when clothes are few, thin, and the space is small.
The drying process would take 3-8 hours, and it is suggested that continuous drainage mode would be more suitable when drying clothes.
