Weekly Cleaning - Duracraft DH-830 SERIES Owner's Manual

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.
• Remove the Natural Cool Moisture™ filter from the Base.
• Empty any water from the Base.
Failure to remove filter during cleaning will destroy the filter.
STEP ONE:
SCALE REMOVAL
REMOVE AND RINSE TRAY™
1. Fill the Remove and Rinse Tray™
with either:
• 1 cup (8 ozs.) of undiluted
white vinegar
• Use DuraRinse™ Humidifier
Cleaner, part no. AC816,
following the instructions on
the bottle.
2. Let solution stand for 20 minutes.
3. With the vinegar or DuraRinse™
in the Remove and Rinse Tray™
clean all interior surfaces with a soft
cloth or brush to help remove scale.
4. Rinse thoroughly with water to
remove scale and cleaning solution.
NOTE: THE USE OF OTHER WATER TREATMENT PRODUCTS AND CHEMICALS
