5. OPERATION
CONTROL PANEL
After switching the power on, all the indicators and the screen will be on for 1 second and then off. After
a buzzer, the power indicator will be on and the appliance will be in the standby mode.
Press this button, the appliance will start to operate in the default automatic mode and conduct high
wind operation, with the initial humidity being 50%RH.
Press this button again, the appliance will stop operating, and the fan will close with a delay.
Auto mode - continuously drying mode - sleep mode cycle: press this button to switch between the
modes, with the corresponding indicator lighting up.
●Auto mode:
- When environmental humidity ≥ set humidity +3%, the fan begins working immediately, and the
compressor begins working after 3 seconds.
- When environmental humidity ≤ set humidity -3%, the compressor stops working and the fan
shuts down after a delay.
- Both fan speed and humidity are adjustable.
●Continuously drying mode:
- The appliance continues to operate with an unadjustable humidity level.
●Sleep mode:
- Long plress MODE button ,the sleep indicator lights up and it starts the sleep function.Press
MODE button one time to close sleep function.
-After 10 seconds of null operation in sleep mode, all indicators turn dark gradually and the wind

speed is automatically switched from high to low. Touch any button to awaken the indicator.
- The fault code is not displayed, the wind speed is not adjustable, but the humidity is adjustable.
In auto mode or sleep mode, press this button to adjust the set humidity: every time the button is
pressed, the set humidity increases by 5% within the range of 30%-80%.
Long press of this button shows the current room temperature that is displayed in double eight lights for
5 seconds, after which the screen automatically returns to display the current humidity. If continuously
pressing this button, the room temperature will be unceasingly shown.
Press the TIMER button to active the timing function, then press HUM/TIME SET button to set time
within the range of 0-24 hours. Each press of this button increases the time value by 1 hour, with its
current number displayed on the screen. Set the time to “00” to exit the timer function, and the
indicator light will extinguish accordingly.
After the time is set, the timer LED is on during the timing period, and turns off automatically after the
period is over.
In the non-timing state: press this button to enter the time-setting state, where the digits flash to display
the set time; during the flashing period, press the adjustment button (or up and down buttons) to adjust
the set time (0 ~ 24h).
In the timing state: press this button to display the remaining set time, and press it during the
digit-flashing period to cancel the timing.
In the running state: set the time to turn off the appliance.
In the standby state: set the time to turn on the appliance.
The wind speed is only adjustable in auto mode.In sleep mode and defrosting period,the wind speed can
not be changed. Press this button to switch between the high and low wind speed shown by the
corresponding wind speed indicator.

Long press of this button turns on the child lock function and the corresponding child lock indicator
lights up, and all buttons are locked and cannot be operated. Another long press of this button turns off
this function and the corresponding indicator, and all buttons resume their functionality.
The child lock function is automatically turned off once the appliance is shut down or the power is off.

6.DRAINAGE
EMPTYING THE WATER TANK
When the tank is full, the appliance will emit a buzzing sound, and the “Water Full” light
will get turned on
Press the POWER button to turn off the appliance.
Pull on the water tank to simply slide it out of the body of the appliance.
Dispose the water by pouring it into an area with a drain or outside.
Clean the inside of the tank as well as the outside.
Place the empty tank back into the appliance.
Press the POWER button to resume operation.
If the “Water Full” light does not extinguish, check if the water tank is correctly positioned.
Warning
1. Do not discard water tank magnets and plastic rivets. Otherwise, the appliance will not
automatically stop operating when the water tank is full, and the condensate will overflow and damage
the floor of the room.
2. Please clean the condensate in the water tank before resetting the work mode of the
appliance.

3. If the water tank is dirty, rinse it with clean water. Avoid using detergents, steel balls, chemical
dust removers, diesel oil, benzene, diluents, or other solvents for the cleaning purpose, as they will
possibly cause the water tank to be damaged and leak.
4. Put the empty tank back into the appliance after cleaning. Otherwise, the “Water Full”
indicator may remain red and the appliance cannot resume operation.

7.CONTINUOUS DRAINING
For continuous operation or unattended dehumidification, please connect the attached drain hose
to the appliance. Condensate can automatically flow into a bucket or drain by gravity.
1.Straighten the drainage pipe
2.Insert one end of the drain hose into the cistern hole and connect the other end to bathroom,
outdoor space, bucket-like container, or the prescribed area for drainage.
Warning
1. Please do not block the drain or drain pipe, otherwise the condensate will flow into the water
tank.
2. Please do not bend the drain pipe. The height of the drain pipe should be lower than the
outlet.
3. The drain pipe shall be securely connected to the outlet;

8.MAINTENANCE
Note: before implementing cleaning and maintenance on the appliance, make sure to turn off the
appliance and pull out the power plug to prevent electric shock.
•CLEANING THE AIR FILTER (every two weeks)
Dust collected on the filter restricts airflow, which reduces the efficiency of the dehumidification system
and can cause damage to the appliance if the dust blocks the filter.
The air filter is removable and requires regular cleaning. Do not operate the appliance without an air
filter, as which might cause the evaporator to be contaminated.
1. Take the water tank out of the appliance’s body, and then pull out the filter from the bottom of the
appliance’s rear shell;
2.Use a vacuum cleaner to gently absorb the dust on the surface.
If the filter is very dirty, wash it with water and a soft detergent and dry it thoroughly afterwards.

3.Put the filter back.

9.TROUBLE SHOOTING
1.FUNCTIONING TEMP.
41°F ≤ Ambient temp. ≤ 95°F
When the ambient temperature is lower or higher than the functioning temperature, the appliance stops
operating.
When 41°F ≤ Ambient temp. ≤ 60°F, the compressor automatically defrosts at intervals; during defrosting,
the compressor stops and the fan keeps operating.

10.DECOMMISSIONING
STORAGE
Long-term storage - If you are not going to use the appliance for an extended period of time
(more than a few weeks), it is the best to clean and dry it completely. Please store the appliance
according to the following steps:
1. Press the power button to switch off and unplug the appliance.
2. Drain the remaining water from the appliance.
3. Clean the filter and let the filter dry completely in a shaded area.
4. Collect the power cord at the water tank.
5. Re-install the filter at its position.
6. The appliance must be kept in an upright position when in storage.
7. Preserving the appliance in a ventilating, dry, corrosive gas-free, and safe indoor space.
ATTENTION:
The evaporator inside the appliance must be dried before the device is packed to avoid component
damage and molds. Unplug the appliance and place it in a dry open area for days to dry it out. Another
way to dry the appliance is to set the humidity level more than 5% higher than the ambient humidity to
force the fan to dry the evaporator for several hours.
DISPOSAL
WARNING!!!
Releasing refrigerant into the atmosphere is strictly forbidden!
Do not dispose electrical appliances as unsorted municipal waste, but use separate collection facilities.
Contact your local government for information regarding the collection systems available. If electrical
appliances are disposed in landfills or dumps, hazardous substances can leak into the groundwater and
get into the food chain, which thus impairs your health and well-being.
