Place the humidifier and cord so that the humidifier will 

not be knocked over.

• 

When not in use, turn the machine off and disconnect 

from power source by removing the plug from the 

outlet.

•  Do not

 overfill the water tank as this may cause electric 

shock.

•  Do not

 use this humidifier in wet environments. 

• 

Keep the humidifier out of reach from children.

•  Do not

 open the base or remove the water level sensor 

for self-servicing.

 unplug your humidifier from the power outlet 

before cleaning your humidifier or detaching the water 

tank from the humidifier base.

 make sure to place the humidifier on a flat, level 

surface before operation.

 fill the water tank with clean water. 

Never

 fill the

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.

To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines.
