Children should not clean or perform maintenance on the humidifier without supervision.
Not for commercial use. Household use only.

Caution: Risk of Leaks and Electric Shock

Do not add essential oils, supplemental water treatment liquids, or water filters into the water tank or base chamber. This will damage the humidifier and cause leaks. Only add essential oils to the aroma pad.

Electromagnetic Fields (EMF)

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.

Power & Cord

Ensure that the plug fits properly into a polarized socket.
Do not handle the power cord or 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 or fire hazard. Please contact Customer Support
