Weekly Cleaning; Scale Removal - Honeywell HWM910 - ENVIRACAIRE Warm Moisture 2 Gallon Humidifier Owner's Manual

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.

• 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

minerals is heavy, follow the CLEANING THE

Unit aside.
