With the unit off and plugged in, press and hold the WIDE SWING button and the POWER ON/OFF button together for at least 3 seconds. A beep sounds and the display shows '12' for 5 seconds. To reactivate, unplug and repeat the procedure.

How do I clean the filter?

Turn off and unplug. Remove the filter from the rear. Use a vacuum cleaner to remove dust. If very dirty, wash with mild detergent in warm water, rinse, and dry thoroughly in the shade before reinstalling. Clean every 2 weeks.

What is the Plasmacluster Ion feature?

Plasmacluster Ion releases positive and negative ions to suppress airborne mold, bacteria, and viruses. It is activated by default in all modes. Press the PLASMACLUSTER button to turn it off or on. Note that it only works when the dehumidifier is running.

Why does the unit stop and the display show a blinking 'H'?

If the room temperature exceeds 41°C, the display shows 'H' blinking and the unit will stop for protection. This is normal. The unit will resume when the temperature drops below the safety threshold.

How do I change the air flow direction?

Press the WIDE SWING button during operation to cycle through positions: Up, Rear, Wide (sweeping), and Off (fixed at current angle). The louver stops moving when you press Off. Do not force the louver manually.

What should I do if the unit is not dehumidifying efficiently?

Check if the filter is clogged (clean it), if the air intake or outlet is blocked, if the room temperature is below 10°C (use with heater), or if doors/windows are open. Also ensure the tank is empty and properly installed.

How do I defrost the unit?

When operated at low temperatures, frost may form on the heat exchanger. The unit will automatically enter defrost mode. During defrost, the fan runs but dehumidification stops. This is normal and the unit resumes automatically once defrosted.

Maintenance

• For safety purposes, turn off and unplug the unit before carrying out any maintenance.
• For clean, sanitary and pro-long use, regular maintenance is recommended.

Water tank (About once a week)

1 Removing and installing the tank lid, tank handle, and tank float.

(1) Detach the tank lid gradually from the left or right toward the opposite side.
(2) Drop the tank handle to the front position as shown in the illustration on the right, and slightly spread out the left and right side arms of the handle so that the shafts come out, and remove the handle from the water tank.
(3) Push the float in the direction ① shown in the diagram and remove it from the hole. With the float in this state, pull it out in direction ②
(4) To reinstall, follow the above procedure in reverse (②→①).
If you do not insert the tank float securely, the tank can overflow, and the unit will not stop. Take due care.

Wash the inside of the water tank.

- After prolonged use, the drain water may cause the tank to go black. If this happens, wash the tank with a sponge, warm water and a mild detergent.

Lever

Wipe the water tank with a soft cloth, and install the tank lid, tank handle, and tank float.

* After having reinstalled these parts, make sure to move the float lever up and down with your finger to confirm that it moves smoothly. If the float sticks, the overflow protection device located behind the lever will not work and the tank may overflow.

Filter

(About once 2 weeks)

* This filter is not intended for air purification.

● A clogged filter will result in reduced dehumidification efficiency and higher power consumption. It can also cause odor.
- If you operate the unit without the filter, dust will accumulate in the unit, which may result in malfunction.

Cleaning the filter

Remove dust and dirt with the corner tool of your vacuum cleaner. If the filter is very dirty, wash it with neutral detergent diluted in warm water. Rinse it off and let it dry well in the shade.

Main body

(About once a month)

Things to remember

The temperature at which the unit can be operated is 5°C to 35°C.

If the room temperature is over 35^ C, the built-in protection system will automatically turn off the unit.

Dehumidifying operation increases room temperature. (The dehumidifier does not have a cooling function.)

The unit generates heat during operation and will become warm. It will blow out warm air, but this is normal and does not indicate a problem with the unit.

Dehumidification capacity will vary based on room temperature and humidity.

● Dehumidification capacity will increase as temperature rises (as shown in the chart on the right).
- In winter when the room temperature is low (below 10°C), use the dehumidifier in combination with a room heater to reduce the drying time.

Wait for 3 minutes before restarting the unit

If the unit is turned off, wait for at least 3 minutes before restarting operation.

If the unit is restarted immediately, the compressor will wait for 3 minutes to start up as part of the unit's self-protection system.
