it up (fig.

Place the upper unit back onto the water 

tank (fig.

).

4  Using the humidifier

Understand the humidity 

indication

The humidifier is equipped with a built-in 

humidity sensor. You can set the target humidity 

level at 40%RH, 50%RH and 60%RH. The 

ambient humidity level displays on the center of 

the control panel from 20%RH to 95%RH.

Note

• 

A comfortable humidity level is from 40RH% to 

60RH%. 

• 

The accuracy of the humidity indication is 

approximately ±10%.

• 

It takes some time to measure the humidity 

level in the room.

Understand the healthy air 

protect alert and lock

The healthy air protect aler t gives you a timely 

warning when the water tank needs refilling. 

When the water in the tank star ts getting low, 

a red indicator   on the control panel star ts 

blinking to tell you that it is time to refill the 

tank (fig. 

e

). It blinks for 30 minutes. After that, 

the indicator remains on before the water tank 

is refilled with water.
The healthy air protect lock always ensures that 

your humidifier does not work without water 

in the tank. When the water tank is empty and 

needs to be refilled, the healthy air protect lock 

shuts off the humidifier after 30 minutes and a 

red indicator lights up. When you refill the water 

tank properly, the humidifier is turned on again.

Note

• 

In sleep mode, the red indicator does not blink, 

it turns on when the water level is low.
