Adding Water to Humidifier:
If the air gets dry, add water to the humidifier tray to add moisture to the air.
(1) Remove the bottom cover.
Hold both ends of the cover and pull toward you to remove the
cover.
(2) Pull out the humidifier tray and add water.
After adding water, gently push the plate back inside and
replace the bottom cover. Be careful not to spill the water, as
spilled water may cause staining, corrosion, or damage.
*If the humidifier capacity is not sufficient, use a humidifier
available on the market.
*The humidifier tray holds approximately 3 pints (1300cc) of
water. The time water lasts varies from 10 to 15 hours, so
check the water level occasionally.
Caution:
G The humidifier tray and the surrounding area are hot when the unit is on. To avoid burns, do not add
water to the tray while unit is on.
G Avoid adding water when the room is susceptible to condensation.
G If the water overflows from the water level hole when adding water, do not add any more water.
Care of Unit Exterior:
Dampen soft cloth with warm water, wring water out well and
wipe the unit.
Caution:
Never use volatile substances such as benzine or thinners, as
they cause fading of paint or deformation of resin.
Care of Air Filter:
Always clean the air filter when the filter indicator lamp starts blinking.
I The filter indicator lamp starts blinking when the dust accumulates on the air filter. In this event, turn
the unit off immediately, wait until the unit cools off and clean the filter.
I Even if the lamp is not blinking, if you think the filter is dirty, clean the filter while you are cleaning the
room (approx. once a week). This will ensure comfortable use.
I The air filter may be removed. Clean both sides of the filter with a
vacuum cleaner or a duster.
I If the filter is greasy, wash quickly with detergent, shake water off and
dry completely.
I After cleaning and drying, replace the filter securely.
