Maintenance and Cleaning

The evaporative, wick-type humidifier adds moisture to the air in the form of water vapor, by using a fan to force air through a moistened-filter medium.

To ensure the proper and efficient oper- ation of your humidifier, the following cleaning and maintenance procedures must be followed.

Failure to follow the recommended care and maintenance instructions could lead to a buildup of micro-organisms, including algae, bacteria, and mildew, which may lead to respiratory or other ailments in some individuals.

WARNING

To reduce the risk of electrical shock:

•  Always unplug before cleaning.

•  Do not immerse product in water or other liquid.

Daily Maintenance:

1.Turn off the humidifier and unplug it from electrical outlet.

2.Lift off the fan enclosure and remove the filter.

3.Remove the water tank and tray and carry them to the sink. Pour any remaining water into the sink.

4.Rinse the water tray and tank thoroughly to remove any dirt or sediment. Wipe clean, then dry with a clean cloth or paper towel.

5.Reinstall the water tray and filter, replace the fan enclosure, and refill the water tank with cool tap water as instructed on page 18.

NOTE: To prolong the life of the filter, it is recommended that you turn over the filter each time you fill the water tank.

6.Wipe the fan enclosure, control panel, and cord with a damp cloth or sponge.

Weekly Cleaning:

1.Turn off the humidifier and unplug it from electrical outlet.

2.Lift off the fan enclosure and remove the filter.

3.Remove the water tank and tray and carry them to the sink. Pour any remaining water into the sink.

4.To remove scale caused by hard water deposits and to clean the tank and water tray, these parts can be either cleaned in a dishwasher or washed by hand.

5.Inspect the filter each week. If it becomes hard to the touch, or shows discoloration (caused by

mineral deposits or mold/mildew buildup), it should be replaced. See page 40 for information about ordering a replacement filter.

6.After cleaning and drying all parts, follow the instructions on page 16 to reassemble the humidifier. If the humidifier will not be used for at least two weeks, see the “Storing the Humidifier” section.
