Symptom

Cause/Remedy

The unit blows warm air

Water does not collect in

the water tank (minimal

dehumidifying results)

The unit does not turn on

(no air comes out)

The unit keeps turning off

The humidity level does

not reach the level set

The hygrometer reading on

the unit differs from other

hygrometers in the room

The louvre does not move

as set

The water tank contains

liquid or white water residue

There is black residue on the

inside of the water tank and lid.

Louvre does

not swing

¡ Dehumidified air passes through heating coils causing it to

warm (this unit is not a cooler). This is not a malfunction.

¡ Check to see if the temperature/humidity is low.

Low room temperature/humidity reduces dehumidifying

effectiveness. Confirm the current humidity reading (in winter,

the air is dry reducing dehumidifying effects to zero). This is

not a malfunction.

¡ Check to see if the power cord is correctly plugged.

➝ Plug the power cord properly into the power socket.

¡ Check to see if anything is blocking the air intake or outlet.

➝ Remove the obstruction.

¡ Check to see if the air filter is clogged.

➝ Clean according to the maintenance procedures.

¡ Check to see if the unit is in FULL AUTO, MILDEW GUARD, or

AUTO.

The unit is automatically controlling the dehumidifier, fan, and standby times.

¡ Check to see if the water tank is full.

➝ Empty the water tank and return it to its original position.

¡ Check to see if the water tank is inserted properly.

➝ Adjust the position of the water tank.

¡ Check to see if the unit is in defrosting mode.

The unit activates defrosting mode when the room temperature

drops below 15°C. The dehumidifier and blower functions stop

during defrosting.

¡ Check to see if the room is not too large.

➝ Use within effective boundaries (floor space).

¡ Check to see if the exits to the room are open.

➝ Refrain from opening doors/windows during operation.

¡ Check to see if steam producing appliances such as kerosene

heaters are on in the vicinity.

¡ Hygrometer readings differ from place to place even if in the

same room. Use the unit humidity reading as an estimate.

¡ Press the Swing louvre switch again.

¡ The residue is from final product testing at the factory. It is not

a result of a malfunction.

¡ The residue is from debris in the air.

➝ Clean according to the maintenance procedures.
