WEEKLY CLEANING We recommend cleaning the humidifier once a week, more often if you have hard water, notice a build up of impurities or detect unpleasant odors. 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 Base. • Empty any water from the Base. NOTE: REMOVE FILTER BEFORE CLEANING. Failure to remove filter during cleaning will destroy the filter. STEP ONE: SCALE REMOVAL STEP TWO: DISINFECTING BASE 1. Fill the Base with either: • 1 cup (8 oz) of undiluted white vinegar or • Use DuraRinse® Humidifier Cleaner, part no. AC-816, following the instructions on the bottle. 2. Let solution stand for 20 minutes. 3. With the vinegar or DuraRinse® in the Base clean all interior surfaces with a soft cloth or brush to help remove scale. WATER TANK/BASE 1. Fill the Water Tank with: • 1 teaspoon of household bleach and • 1 gallon of water Pour some of this solution into the Base. 2. Let solution stand for 20 minutes. 3.
