NOTE: THE USE OF OTHER WATER
TREATMENT PRODUCTS, CHEMICALS,
SOAPS, DETERGENTS OR ABRASIVE
CLEANSERS NOT RECOMMENDED IN THE
MANUAL MAY CAUSE DAMAGE TO THE
HUMIDIFIER OR AFFECT PERFORMANCE.
We recommend cleaning the humidifier weekly, more often if you have hard water
or 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. Wait at
least 10 minutes for the unit to cool.
• Remove the Water Tank.
• To remove the Power Unit, pull the Latch to
release (found under the Water Tank) and lift the
Power Unit (Fig. 6). Turn upside-down to check
condition of heating element. If build-up of
minerals is heavy, follow the CLEANING THE
HEATING ELEMENT instructions. Set the Power
Unit aside.
• Empty any water from the Base and Removable Tray.
