Care and Cleaning

CAUTION: ALWAYS TURN OFF THE POWER SWITCH AND DISCONNECT
THE POWER CORD FROM THE ELECTRICAL OUTLET BEFORE CLEANING.

Daily Maintenance:

1.

Lift the Water Tank from Base and empty all water from the Reservoir. Remove the Tank Cap
and drain any water from the Water Tank. Wipe it clean with a soft, damp cloth. The Mist
Nozzle should be removed during cleaning to prevent damage.

2.

Do not

immerse the Base in water. Gently wipe the Reservoir with a soft, clean, wet cloth.

Do not

attempt to remove or in any other way modify the Water Sensor. 

Use care

when

wiping around the Water Sensor; it is delicate and can be easily damaged. Rinse the Water
Tank with lukewarm water after each use. For storage, wipe dry with a soft, clean cloth. Keep
water away from the Air Outlet.

3.

Do not

use detergent to clean any water-containing parts of the humidifier. Detergents and

the film they leave behind can affect the output of the humidifier. 

Do not

use abrasive

cleansers or brushes.

4.

Do not

leave water in the Water Tank or Reservoir 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.

Weekly Maintenance:

1.

Thoroughly clean humidifier every week using a solution of bleach and water (one teaspoon
of bleach in one gallon of water). Fill tank partially with this solution, let stand twenty (20)
minutes, shaking vigorously every few minutes, drain and rinse with clean water until the
bleach smell is gone. 

Do not

use detergents as they will interfere with performance of the

humidifier.

2.

Wipe the Reservoir with a soft cloth dampened in the solution. Rinse area thoroughly before
proceeding.

3.

If mineral deposits are evident around the Nebulizer and Water sensor, clean their surfaces
with a soft, clean cloth and a small amount of undiluted white vinegar. If necessary for
removal of mineral deposits, mix a solution of 50% white vinegar and 50% water and fill
the base with enough solution to cover the Nebulizer. 

Do not

use detergents. 

Do not

immerse the Base in water. Allow it to soak for an hour. Then use a cotton swab to gently
loosen build up on the Nebulizer. Rinse out the Reservoir and wipe clean. 

Do not touch

Nebulizer with bare fingers

as any fingerprints or other residue can affect mist output.

Be careful not to damage the Water Sensor.

4.

All surfaces should be thoroughly cleaned with water prior to reuse. The Tank Cap can be
soaked in a solution of 50% white vinegar and 50% water if necessary to remove deposits.

End of Season Maintenance

1.

Follow above weekly cleaning procedure at the end of the humidification season, or when
the humidifier will not be used for several days, being sure to dry all parts. Allow the Water
Tank to air dry before storing. 

Do not

store with water inside.

2.

Leave Tank Cap partially loosened during storage to prevent Tank Cap and Gasket from
sticking together. This will prolong the life of the gasket.

3.

Clean the Tank and Base after long periods of storage.
