plug with wet hands. Keep the plug
and power cord away from liquids.
• Your humidifier has a polarized plug
(one prong is wider than the other),
which fits into a polarized outlet only
one way. This is a safety feature to
reduce the risk of electric shock. If
the plug does not fit, reverse the
plug. If it still does not fit, do not
use the plug in that outlet. Do not
bypass this safety feature.
• If the power supply cord is damaged,
it must be replaced by Arovast
Corporation or similarly qualified
persons in order to avoid an electric

Auto Mode
Auto Mode uses the humidifier’s sensor to
automatically adjust the mist level (or turn it
o) to maintain a comfortable and healthy
level of humidity.
• Auto Mode automatically adjusts the
mist level to maintain 40–50% relative
humidity. You can change the target
humidity level in the VeSync app.
• By default, Auto Mode uses Automatic
Stop. The humidifier will stop misting
when the highest target humidity level is
reached. If the humidity drops below the
target humidity level, the humidifier will
begin misting again.
• In the VeSync app, you can turn
Automatic Stop on/o. If Automatic Stop
is o, the humidifier will keep running on
Low mist level when the highest target
humidity level is reached.
• If Auto Mode is selected when the
humidity is higher than the target
humidity range, the humidifier will not
start misting until the humidity lowers.
Note: The VeSync app is continually updated
and app features will expand.
The VeSync app allows you to access
additional smart functions, including those

Important Tips
Your humidifier must have the correct level of
water in the base chamber to work properly. If
there is too much water in the base chamber,
the humidifier cannot create mist.
• Never pour water directly into the
base chamber. [Figure 3.4] Only add
water to the water tank. The humidifier
will automatically release the correct
amount of water into the base chamber.
• Avoid moving or shaking the humidifier.
[Figure 3.5] This may cause the water
tank to release too much water into the
base chamber.
• Before moving the humidifier, turn it o,
unplug it, and remove the water tank.
• If your humidifier doesn’t produce mist
correctly, check the max water line to
see if there is too much water in the
base chamber. Pour out extra water if
water is over the max line. [Figure 3.6]
Note: The max water line is only for this purpose.
Do not pour water into the base chamber.

CARE & MAINTENANCE
Note:
• All maintenance should be done on a water-
resistant surface, such as a kitchen counter.
• Change the water daily to avoid bacteria growth.
• Use a tissue or cloth to clean the nozzle regularly.
• If not using the humidifier for 1 week or longer,
do not leave water inside. Clean and dry the
humidifier instead.
Note: When pouring out water, hold
down the float to ensure that it does
not fall out of the base chamber.
Note:
• Never immerse the base in water or liquid.
Do not place any part of the humidifier in a
dishwasher.
• Do not use detergents to clean the humidifier.
Cleaning
You should clean your humidifier every
week, and when you’re ready to store it.

Problem Possible Solution
Humidifier doesn’t turn on, or
turns o unexpectedly.
Plug in the humidifier and turn it on.
Add purified or distilled water to the water tank.
Check to see if the humidifier is in Auto Mode. Depending on
Auto Mode settings, the humidifier may automatically turn o
when the humidity level is above the target level.
Little or no mist comes out.
Turn the mist level to a higher setting.
Fill the water tank.
There may be too much water in the base chamber. Empty the
base chamber. Refill the water tank (not the base chamber) and
place the water tank properly onto the base.
Make sure the air inlet on the bottom of the base is not blocked.
The humidifier should not be set on carpet or other surfaces that
may block the air inlet.
Make sure the nozzle is not blocked or clogged.
Make sure the humidifier is on a level surface.
The water temperature may be too low. Turn the mist level to
the highest setting and let the humidifier run for a while, then
adjust to the desired setting.
If the water tank or base was washed with detergent, rinse
thoroughly with clean water to remove any detergent.
Clean the water filter assembly (see page 15) or replace it with
a new one (see page 25).
Humidifier uses water too quickly.
The humidifier uses up water based on the environmental
temperature and humidity. If your environment is cold and/or
dry, the humidifier will run out of water faster.
Humidifier produces an
unusual smell.
If the humidifier is new, unplug and rinse all parts, then place in a
cool, dry place for 12 hours.
If essential oils were diused, clean all parts with white vinegar
(follow the descaling instructions on page 16), and allow the
humidifier to dry.
Clean the water tank and base chamber (see Care & Maintenance,
page 15).
White dust appears around the
humidifier.
We recommend using purified or distilled water to fill the
humidifier. Avoid using water with high mineral content.
Clean the humidifier (see Care & Maintenance, page 15).
