WEEKLY CLEANING

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 min- erals is heavy, follow the CLEANING THE HEAT- ING ELEMENT instructions. Set the Power Unit aside.
