Power & Cord
Electromagnetic Fields (EMF)
• Ensure that the plug fits properly
into a polarized socket.
• 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.
• Do not handle the power cord or
plug with wet hands. Keep the plug
and power cord away from liquids.
• If the power supply cord is
damaged, it must be replaced by
Arovast Corporation or similarly
qualified persons in order to avoid
an electric or fire hazard. Please
contact Customer Support (see
page 27).
• Unplugging the power cord
will disable remote control of
the humidifier and temporarily
disconnect the humidifier from
VeSync and other third-party apps.
This humidifier complies with all
standards regarding electromagnetic
fields (EMF). If handled properly and
according to the instructions in this
user manual, the appliance is safe
to use based on scientific evidence
available today.
Swallowing can lead to chemical burns,
perforation of soft tissue, and death.
Severe burns can occur within 2 hours
of ingestion. Seek medical attention
immediately.
SAFETY INFORMATION (CONT.)
• Only add essential oils to
the aroma pad.
• Do not add essential
oils, supplemental water
treatment liquids, or water
filters into the water inlet
tank, base chamber, or
water tank.
Caution: Risk of Leaks
and Electric Shock
• Place sticky tape around both sides
of the battery and dispose of it
immediately in an outdoor trashcan
or recycle safely;
• Store spare batteries securely;
• Empty recycling units on a regular
basis;
• Use non-transparent containers to
keep the batteries out of view.
This product contains a coin/button
battery.
WARNING: CHEMICAL
BURN HAZARD.
KEEP OUT OF REACH
OF CHILDREN.

These sorts of symptoms vary or
fluctuate, with the pain increasing and
then subsiding.
A specific symptom to button and coin
battery ingestion is vomiting fresh (bright
red) blood. If a child does this, seek
immediate medical help.
The lack of clear symptoms is why it is
important to be cautious with “flat” or
spare button or coin batteries in the
home and the products that contain them.
Be aware that even used button or coin
batteries may cause injury.
Unfortunately, it is not obvious when
a button or coin battery is stuck in a
child’s esophagus (food pipe). The
child might:

VeSync App Functions
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.
The VeSync app allows you to access
additional smart functions, including those
listed below.
Note: The VeSync app is continually updated
and app features will expand.
• Do not place the humidifier on an
inclined surface.
• Do not add water directly into the
base chamber or mist tube. Only
add water to the water inlet tank
or directly into the water tank. The
humidifier will automatically deliver
the correct amount of water into the
base chamber.
• Do not remove the water inlet tank
during filling.
Remote Control From Your Phone
• Turn the humidifier on/o.
• Cycle through mist levels.
• Turn Auto Mode on/o.
• Set a target humidity level.
• Turn Sleep Mode on/o.
• Turn the display lights on/o.
Monitor Humidity Levels
• Check current humidity levels in the
humidifier’s environment.
Set Timers & Schedules
• Program individual timers or create a
schedule for your smart humidifier.
Third-Party Voice Control
• Compatible with Amazon Alexa and
Google Assistant™ for voice commands.
Figure 4.1
• Avoid moving or shaking the
humidifier. [ Figure 4.1 ] This may
cause the water tank pump to
deliver too much water into the base
chamber or reduce the amount of
water in the base chamber.
• Before moving the humidifier, turn it
o and unplug it.
