CARE AND MAINTENANCECARE AND MAINTENANCE

Frequency of maintenance cycle will depend on the hardness or the impuri
ties 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 lter.
1
Remove the Water Tank and
Humidifying Tray.
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
When using lemon juice,
it is recommended 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 odour and
affect the performance and/or appear-
ance of the unit.
* Do not scrub the Humidi-
fying Filter, rinse gently
under lukewarm water
only.

6

Attach the Humidifying Filter
to the Humidifying Tray, and
replace 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 peri-
ods of time, dry the
Humidifying Filter
completely 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 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.
