SAFETY INFORMATION (CONT.)
Power & Cord
· 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.
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.

Caution: Risk of Leaks and Electric Shock
· 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: HOT Water Vapor
· Let nozzles and mist tube cool before touching or cleaning.

WARNING
INGESTION HAZARD: This product contains a button cell or coin battery.
WARNING: CHEMICAL BURN HAZARD.
· DEATH or serious injury can occur if ingested;
· A swallowed button cell or coin battery can cause Internal Chemical Burns in as little as 2 hours;
· KEEP new and used batteries OUT OF REACH of CHILDREN;
· Seek immediate medical attention if a battery is suspected to be swallowed or inserted inside any part of the body;
· Remove and immediately recycle or dispose of used batteries according to local regulations and keep away from children. DO NOT dispose of batteries in household trash or incinerate;
· Even used batteries may cause severe injury or death;
· Call a local poison control center for treatment information;
· Only use with a 3V CR2025 battery;
· Non-rechargeable batteries are not to be recharged;
· Do not force discharge, recharge, disassemble, heat above (manufacturer’s specified temperature rating) or incinerate. Doing so may result in injury due to venting, leakage or explosion resulting in chemical burns;
· Ensure the batteries are installed correctly according to polarity (+ and -);

· Do not mix old and new batteries, different brands or types of batteries, such as alkaline, carbonzinc, or rechargeable batteries;
· Remove and immediately recycle or dispose of batteries from equipment not used for an extended period of time according to local regulations;
· Always completely secure the battery compartment. If the battery compartment does not close securely, stop using the product, remove the batteries, and keep them away from children.
· 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.
Unfortunately, it is not obvious when a button or coin battery is stuck in a child’s esophagus (food pipe). The child might:
· Cough, gag or drool a lot;
· Appear to have a stomach upset or a virus;
· Be sick;
· Point to their throat or stomach;
· Have pain in their abdomen, chest, or throat;
· Be tired or lethargic;
· Be quieter or more clingy than usual or otherwise “not themselves”;
· Lose their appetite or have a reduced appetite;
· Not want to eat solid food / be unable to eat solid food.
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.

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.
· 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.
· 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.

Figure 4.1
· Before moving the humidifier, turn it off and unplug it.
