HOW TO CLEAN AND CARE
CAUTION: Before cleaning the unit, turn power off, unplug from the wall outlet and unplug
the AC Adapter plug from the top of the humidifier.
CLEANING THE TRANSDUCER/ULTRASONIC MEMBRANE
The transducer/ultrasonic membrane must be cleaned to remove water mineral deposits when
the red LED is illuminated above the clean transducer/ultrasonic membrane symbol. Failure to
do so may cause reduced or no mist output.
1. Push the 2 side
lock buttons to
remove the top
cover.
4. Clean the transducer/ultrasonic
membrane and float with a 50/50 mix of
white vinegar and water on a cotton
swab. Wipe off with a damp cotton swab.
NEVER touch the transducer/ultrasonic
membrane with your fingers; the natural
oils in the skin can damage the surface.
NEVER submerge the top in water or
any other liquid.
2. Pour out any water
remaining in the
tank.
3. Open the transducer/ultrasonic membrane
door and remove the float to access the
transducer/ultrasonic membrane.
5. After cleaning,
reassemble the
humidifier, fill with
water, plug in, and
turn on.
