A NOTE ABOUT HUMIDITY
It is best to keep the humidity level at about 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 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 and
walls, especially wallpaper.
To eliminate excessive humidity, especially in small rooms, leave the room door open
and adjust the mist intensity control setting.
MAINTENANCE
CAUTION:
Always be sure that the appliance is unplugged and switched OFF
before cleaning or attempting to store the item. NEVER PLUG OR
UNPLUG UNIT WITH WET HANDS.
DO NOT leave water in water tank or water basin when unit is not
in use as it may result in the build up of mineral deposits and
bacteria that can inhibit the output efficiency of the humidifier.
PLEASE NOTE that if water remains in the water tank for more
than a day or two, bacterial growth is possible.
ALWAYS use fresh cool water when using unit.
NOTE:
When removing water tank, water may accumulate under vapor lid and on the
bottom of the water tank. It is recommended to have a dry cloth ready to dry wet
surfaces.
DISINFECTING THE WATER TANK AND WATER BASIN
1. Fill water tank with 1 teaspoon of household bleach in 1 gallon of water. Let
stand for twenty minutes, shaking vigorously with two hands every few minutes,
drain and rinse with clean water until the bleach smell is gone. Dry with a clean
cloth or paper towel.
2. Wipe the water basin with a soft cloth dampened in the bleach and water
solution. Rinse the water basin with cool water to remove any bleach smell. DO
NOT IMMERSE WATER BASIN IN WATER.
3. Wipe all exteriors surfaces of the base with a soft, dry cloth. Do not immerse the
base in water or use water to clean the base. An electric shock may result or the
humidifier may be damaged.
