Scale Removal - Duracraft DH-890 Series Owner's Manual

W E E K LY C L E A N I N G
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
• 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.
