Brush or use a high pressure nozzle to blow off the dust.

The water level is approximately six minutes full. Adjust the water level of the water tank, adjust the height of the water tank [adjust the screws on both sides]

The water stored in the humidifier should be replaced once a month to ensure water quality. Clean and smooth water flow.

10. There are two over-temperature protectors in the distribution box. Please do not use it for debugging.

Fixed point = temperature set point +20 ° C ~ 30 ° C
