WEEKLYCLEANING

We recommend cleaning the humidifier once a week, more often if you have hard water or notice a build up of impurities or detect unpleasant odors.

NOTE: THE USE OF OTHER WATER TREATMENT PRODUCTS MAY DAMAGE THE FILTER OR HUMIDIFIER.

Cleaning involves two steps SCALE REMOVAL and DISINFECTING. Be sure to perform these in the proper order to avoid harmful chemical interactions.

•First, turn off and unplug the humidifier.

•Remove the Water Tank and Motor Housing.

•Remove the Natural Cool Moisture® filter from the Rinse-to-Clean®Base.

•Discard any residual water from the Base.

•Clean all outside surfaces with a dry, soft cloth. DO NOT USE WATER. THIS MAY DAMAGE THE HUMIDIFIER OR CAUSE ELECTRIC SHOCK.

NOTE: Remove filter before cleaning

Failure to remove the filter during cleaning will destroy the filter

STEP ONE:

SCALE REMOVAL

3.With the vinegar or DuraRinse® in the Rinse-to-Clean®Base clean all interior surfaces with a soft cloth or brush to help remove scales.
