z For the symptoms listed below, refer to the remedies listed right.
Symptom
The unit blows warm air.
Water does not collect in the water
tank (minimal dehumidifying results).
The unit does not operate
(no air comes out and the
louvre does not swing).
The unit stops.
Stops after a
short time.
The unit continues to operate
even though it is turned OFF.
The humidity level does not
drop to the set level easily.
The hygrometer reading on
the unit differs from other
hygrometers in the room.

z The unit blows out warm air because dehumidified air passes through
the re-heater. (There is no cooler function.) This is not a malfunction.
z Check to see if the temperature/humidity is low.
At first, confirm the current humidity. Low humidity reduces dehumidifying
effectiveness. (In winter, the dry air makes the humidity low, and the
amount of water collected is decreased.) This is not a malfunction.
z Check to see whether the power cord is off.
g Plug the power cord fully into the power socket.
z Check to see if anything is blocking the air intake or outlet.
g Remove the obstruction.
z Check to see if the operation is performed in ECO AUTO and EASY mode.
g The unit automatically switches from dehumidification to air
blowing and stops.
z Check to see if operation is being performed in the MILDEW GUARD mode.
g This operation ends automatically when the humidity drops
and will stop in 4 hours as minimum.
z Check to see if the pre-filter is clogged.
g Clean according to the "Maintenance" procedures.
z Check to see if operation is being performed in the INTELLIGENT
LAUNDRY mode.
g If the room temperature drops to approximately 5°C or below, the
operation will stop in approximately one hour. The reason for this
is that if the room temperature is too low, it becomes difficult to
remove moisture from the laundry and humidity does not change. P10
z Check to see whether water tank is full.
g Empty the water tank and return the water tank to its original position. P19
lights.
z Check to see if the water tank is inserted properly.
g Adjust the position of the water tank.
z Check to see if the unit is in DRYING INSIDE operation.
The unit starts DRYING INSIDE operation automatically after
ending normal operations.
z Check to see if the room is too large.
g Use the unit for the specified area range.
z Check to see if the windows and doors are opened too often.
g Try to keep the room closed during operation.
z Check to see if steam producing appliances such as kerosene
heaters are on in the vicinity.
z Hygrometer readings differ from place to place even if in the
same room. Use the unit humidity reading as an estimate.
z Press the SWING LOUVRE switch again.
z When the power lamp is ON, it operates intermittently.
z When the operation ends, the louvre closes.
z The residue is from final product testing at the factory and is not
a malfunction.
z The residue is from the dirt in the air.
g Clean according to the "Maintenance" procedures.
