Sharp KC-830U Humidifying Filter, Preparing the descaling solu- tion, For using citric acid

CARE AND MAINTENANCE

When cleaning the unit, be sure to first unplug the power cord, and never handle the plug with wet hands. Electrical shock and/or bodily injury may occur as a result.

HUMIDIFYING FILTER

Care Cycle

Once a month or when the Filter Indicator Light is on.

Frequency of maintenance cycle will depend on the hardness or the impurities of the water that you use; the harder the water the more often descaling will be necessary.

Pay attention not to spill water when cleaning the filter.

1 Remove the Water Tank and

Humidifying Tray. (See E-15)

2 Remove the Humidifying filter from the Humidifying Tray.

Avoid spilling water from the Humidifying Tray.

3 Preparing the descaling solu- tion.

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 1/2 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 necessary). Combine 1/4 cup lemon juice and 3 cups of lukewarm water in a con- tainer large enough to hold the Humidify- ing filter and stir well.

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

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

5 Rinse the Humidifying filter re- peatedly 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 Hu- midifying filter, rinse gently under lukewarm water only.

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

•The Humidifying filter does not need to be oriented in any particular position(forward/backward, up/down)

•When not using the unit for a long period of time, dry the Humidi- fying filter com- pletely before replacing.

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

You may notice reddish-brown or white deposits forming on the surface of the Humidifying filter. These impuri- ties (calcium, etc.) are due to the im- purities contained in tap water; this is not a defect. Replace the Humidifying filter when it is covered completely in white deposits.
