back on. You can also take the water tank out and ll water directly into the
tank, and put the water tank back into the main base.
• Check if the rated voltage meets the input voltage, and plug into the
socket. The display will light up and it beeps one time. 1 second later, the
display will turn off, and the “on/off” button will turn red, meaning the
humidier is in standby mode.
• Touch the “on/off” button, the display will light up, and it will start to
work in AUTO mode. The display shows the auto symbol and current
humidity. 10 seconds later, the display shows current temperature, and
then change into humidity. Current temperature and humidity showing will
change once every minute.
• Humidier will decide running humidity based on current temperature as
below.
• Constant humidity: touch the HUMIDITY button and you can select the
humidity from 30%RM to 75%. Touch the button once and it will increase
by 5%RH each time. When it reaches 75%, touch again and the display will
show “—” and the humidier will go back to AUTO mode. After setting
the preferred humidity, humidier will keep the memory and conrm by
ashing 3 seconds. Once the display switches to show current humidity, it
means that the setting is nished, “%” will ash on the display.
– When setting humidity is 1%RH~9%RH higher than current humidity, mist
output speed will run by the lowest (the rst) speed.
– When setting humidity is 10%RH~15%RH higher than current humidity,
mist output speed will run by the middle (the third) speed.
– When setting humidity is 15%RH higher than current humidity, mist
output speed will run by the highest (the fth) speed.
– When current humidity is higher than setting humidity, humidier will
turn into sleep state. Once current humidity is 3%RH lower than setting
humidity, humidier will re-work in previous working mode till water
shortage.

Check and clean particles
in water outlet of water tank
that led to leakage. If no
leaks, replace into base.
The following is not considered faulty operation:
• If your water is very hard (containing abnormally high levels of minerals)
the humidier may produce white dust. This is not a malfunction. The
solution would be to clean the lter more often or use softer water.
• If you stand very close to the humidier, you will hear the gurgling sound
of water. This is normal.
• The humidier operates very quietly but it is not completely silent. Noise
levels less than 35dB(A) is considered normal.
MAINTENANCE
In case the water is hard, meaning the water contains too much calcium and
magnesium, it can cause a “white powder” problem and leave heavy scales
on the surface of water basin, transducer, and inner surface of the water tank.
Scales on the surface of transducer will let the humidier work improperly.
Empty the tank and rell every third day. Before relling, clean it with fresh
tap water or cleaning agents if required by the manufacture. Remove any
scale, deposits, or lm that has formed on the sides of the tank or on interior
surfaces and wipe all surfaces dry.
