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 alert gives you a timely
warning when the water tank needs refilling.
When the water in the tank starts getting low,
a red indicator on the control panel starts
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.
