Your Vicks®Humidifier comes fully assembled and ready to use.
First Time Use
Read all instructions before using this appliance. If you have breathing 
difficulties, consult your doctor before using any humidifier.
Filling the Humidifier
1. Unpack Humidifier and remove all packaging materials.
2. Place Humidifier at least FIVE inches away from walls and heat sources, on a FIRM, 
FLAT, LEVEL surface. Place on a water-resistant, non-conducting surface for protection 
from inadvertent spillage. Do not place any object over the Humidifier; it could block 
air openings.
3. Completely unravel power cord. Inspect power cord for signs of damage before use. If 
cord is damaged, DO NOT use product, please call 1-800-477-0457.
4. Keep cord away from heated surfaces and out of the way, where it cannot be stepped on 
or tripped over.
5. Remove Tank using Tank Handle. Turn Tank over and carefully remove Fill Cap by 
turning Fill Cap counterclockwise. Fill the Tank with cool tap water. WARNING: Never 
use hot water — may cause damage to internal components. Do not add 
any type of medication or additive to the water.
6. Make sure the circular rubber Cap Gasket (O-Ring) is in place before replacing Fill Cap 
on Tank (this prevents water leakage). To tighten, turn Fill Cap clockwise.
7. When carrying Tank always use two hands (one on Handle, one on the Fill Cap). Insert 
Tank back into Base. 
Distilled Water Recommended where Hard Water is present
In certain areas, tap water is very hard, containing a higher than normal concentration of 
various minerals. These minerals can be emitted into the air, possibly causing adverse 
reactions in people with breathing difficulties. In such cases, use only distilled or 
demineralized water and clean the humidifier every day.
If you have hard water, you may notice white dust forming on furniture near your humidifier. 
This can easily be wiped off with a damp cloth. To avoid white dust, use distilled or 
demineralized water.
