Pay attention not to spill water when cleaning the filter.

3 Preparingtion. the descaling solu-

Citric acid, available at some drugstores, or 100% bottled lemon juice are used for descaling. Choose either one to use, and prepare the descaling solution.

<For using citric acid>

Dissolve 3 teaspoons of citric acid and 2 /2 cups of lukewarm water in a suitable container, and stir well.

<For using lemon juice>

100% bottled lemon juice can be used for descaling. Use only 100% bottled lemon juice with no pulp (strain juice if neces- sary). Combine 1/4 cup lemon juice and 3 cups of lukewarm water in a container large enough to hold the Humidifying filter and stir well.

4Pre-soak the Humidifying filter in the solution for 30 minutes before cleaning.

When using lemon juice, it is recommended to pre- soak longer than citric acid.

5 Rinse the Humidifying filter repeatedly with lukewarm water to remove all the solution resi- due.

Inadequate rinsing may cause odor and affect the performance and/or appear- ance of the unit.

* Do not scrub the Humid- ifying filter, rinse gently under lukewarm water only.

6Attach the Humidifying filter to the Humidifying Tray, and re- place the Humidifying Tray in the unit.

•The Humidifying filter will not fit if placed in backwards. Be sure there is no gap between the Humidifying tray and the unit when the Humidifying Tray is replaced in the unit. The unit may not operate properly if the Humidifying Tray is not properly replaced in the unit.

•When not using the

unit for a long pe- riod of time, dry the Humidifying filter completely before replacing.

7 Plug in the unit, turn power ON, and press the Filter Reset But- ton on the display more than 3 seconds to reset.

You may notice reddish-brown or white deposits forming on the surface of the Humidifying filter. These impurities (cal- cium, etc.) are due to the impurities con- tained in tap water; this is not a defect. Replace the Humidifying filter when it is covered completely in white deposits.
