Cleaning The Water Tank
- Remove the water tank and pour out the remaining water in the device.
- Take out the filter and clean it separately with a brush or cotton swab.

- When there are water stains that are difficult to remove, you can add an appropriate amount of mild detergent to soak for 30 minutes and then clean them.
Note: Do not use organic solvents, strong acids, strong alkalis, or other substances for cleaning.
Cleaning The Sealing Ring
If there are objects in the sealing ring of the water outlet of the water tank, it will cause the sealing to be loose and cause water leakage. Please lift the spring, and use a cotton swab to carefully remove the objects around the sealing ring at the water outlet.
Cleaning The Sink
Please clean the sink with a damp cloth or brush.
Notice
It is not recommended to directly rinse the sink with water to avoid water splashing into the base from the air outlet. If water drips into the base, it will directly affect the normal operation of the product.
When cleaning the sink, if you accidentally drop water into the air outlet, do not plug in the device, and place the device on the front. Then let the water drain through the base drain hole, and drain in the ventilated place for 3 days, until the water is fully evaporated, before use.
