CARE AND MAINTENANCE
HUMIDIFYING FILTER
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.
1 Remove the Water Tank and
Humidifying Tray.
2 Remove the Humidifying fi lter
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 neces-
sary). Combine 1/4 cup lemon juice and
3 cups of lukewarm water in a container
large enough to hold the Humidifying fi lter
and stir well.
4 Pre-soak the Humidifying fi lter
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 fi lter
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.

Pay attention not to spill water when cleaning the fi lter.
Care Cycle Once a month or when the Filter Indicator Light is on.
* Do not scrub the Humid-
ifying filter, rinse gently
under lukewarm water
only.
6 Attach the Humidifying fi lter 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 fi lter. These impurities (cal-
cium, etc.) are due to the impurities con-
tained in tap water; this is not a defect.
Replace the Humidifying fi lter when it is
covered completely in white deposits.
