1. Use this humidifier only as described in this manual. Other use not recommended may cause fire,
electric shock or injury to persons.
2. Always have water in the water tank when operating the unit.
3. Use only clean, cool tap water to fill the tank. If you have hard tap water, it is strongly suggested to
use distilled water.
4. Be sure the cap of the water tank is firmly tightened.
5. When adding water to the tank, make sure water does not enter the mist output opening.
6. During operation, rotate the mist nozzle so it aims away from children, walls and furniture.
7. This product is intended for household use ONLY and not for commercial, industrial or outdoor use.
8. Do no add medication of any type into the nozzle, base or water tank.
9. Do not cover any openings on the unit or insert objects into any openings.
10. Do not tilt or tip the unit or attempt to empty or fill while in operation.
11. Do not leave the unit unattended in closed rooms as the air could become saturated and leave
condensation on walls or furniture. Always leave the room door / window partly open.
12. To protect against electric shock, do not immerse unit, plug or cord in water or other liquids.
13. This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of shock,
this plug is intended to fit only one way in a polarized outlet. If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician. DO NOT attempt to defeat this
safety feature.
14. Keep the cord away from heated surfaces and areas where it could be walked on or tripped over.
15. Use only a 110-120V AC outlet
16. Close supervision is necessary when any appliance is used by or near children.
17. Turn the unit OFF and unplug from the outlet when not in use, when moving from one location to
another and before cleaning.
18. To disconnect, first turn the unit OFF, grip the plug and pull from the wall outlet. Never pull the plug by
the cord.
19. Do not operate the humidifier in the presence of explosive and/or flammable fumes.
20. Do not place the humidifier or any parts near an open flame, cooking or other heating appliance.
21. Do not operate humidifier with a damaged cord or plug, or if the product malfunctions, or dropped and
damaged in any manner (see warranty).
22. The use of attachments not recommended by the manufacturer may be hazardous.
23. Place the humidifier on a flat, level surface away from direct sunlight.
24. Do not operate if the housing is damaged.
25. A loose fit between the AC outlet (receptacle) and plug may cause overheating and a distortion of the
plug. Contact a qualified electrician to replace loose or worn outlet.
To prolong the life of this humidifier, using distilled water is highly
recommended. Do not add fragrance or oil in the water, it will cause the machine
to malfunction and void the warranty.
It is best to keep the humidity level between 30~50 percent of relative humidity.
The comfort level of humidity will vary from room to room and with changing room conditions.
In cold weather, windows and even some walls may fog or develop frost from excessive indoor
humidity. If this occurs, reduce the mist intensity setting or humidity setting to avoid damage from
condensed water dripping on windowsills.
Too much humidity in the room may allow moisture to accumulate on surfaces where bacteria and
fungi can grow. Moisture that gathers may also damage furniture, walls and wallpaper.
To eliminate excessive humidity, especially in smaller rooms, leave the room door open and adjust
the humidity and mist intensity controls accordingly.

Remove water tank by grasping the housing firmly and pull upwards.
Turn water tank over and turn the cap counter-clockwise to open. Fill with COOL tap water or
Replace the fill cap by turning clockwise – do not over tighten.
NOTE: When carrying a filled water tank, place one hand under for support and do not carry by the mist
nozzle. Do not add fragrance or oil in the water – it will cause malfunction of the unit!
Place water tank back in place, making sure the tank is correctly aligned with the body.
Plug in power source and the Power Indicator will light up.
Press On/Off button, LCD panel will display settings and unit will begin to deliver mist output.
The temperature and humidity sensor is a detachable design. Affix it to the unit or nearby surface to
read ambient room temperature and humidity level.
Adjust the mist nozzle as desired (it turns 360°).
Once the water tank is in place, do not attempt to move the humidifier. If it has to be moved, unplug
the unit and drain water from the base before moving.
Once the water tank is in place or during operation, do not attempt to pick up the water tank. This will
cause excess water to collect in the base and reduce or cease mist output. To move the unit or add
water to the tank, first unplug power and drain water from the base.
Do not point the mist nozzle directly at the hygrostat. Do not spray or pour water on the hygrostat.
This will cause the hygrostat to become defective in reading the correct room humidity level. If wet, it
will read close to 100% humidity and unit will not produce any mist.
During the first few minutes of operation, some mist may escape from the crevice where the water
tank joins the base – this is normal and not a defect.

This unit is equipped with the following protection features:
Water Shortage Protection: If the water within the tank falls below a certain level, the unit will
automatically stop operating.
Humidity Control: When ambient humidity achieves the set humidity level, unit will stop mist output.
Tank Alignment Control: When tank is not properly placed or moved out of position during operation,
unit will automatically shut down.
Save the box for off-season storage.
Clean the tank, reservoir and all part thoroughly and dry before storage.
If water is left in the unit during storage, it may harden and leave deposits that may affect the unit
from operating properly.
Leave the cap of the water tank loose. This will prevent the cap and gasket from sticking together and
prolong the life of the gasket.
