Modes ¡ EASY DEHUMIDIFYING ¡ LAUNDRY The unit operates intermittently controlling the airflow to remove the damp feeling in the air. (There is no need to set the humidity level) When the room temperature is high, the blower operates to decrease the damp feeling. The unit operates for 12 hours and automatically switches off. 50 0 20 Room temperature is below 27°C - the unit automatically sets the humidity level according to the temperature.
¡ AUTO Information The unit maintains the humidity level by automatically controlling airflow and operating intermittently as necessary. All you have to do is set the humidity level. ¡ The unit turns off when current humidity decreases past the set humidity level, and restarts when the level is exceeded. ¡ The unit operates for 6 minutes continuously regardless of the humidity level immediately after turning the power on.
¡ Drying inside The inside of the unit can be dried to suppress mildew growth on the cooler. On days the dehumidifier is used, drying inside is recommended. Automatic operation To activate drying inside after every use. Press while the unit is on ¡Drying inside standby (Drying inside lamp lit) Manual operation To activate drying inside by pressing a button.
[Lamp Indicator] Tank full light The unit automatically shuts down and indicates with the light and sound that the water tank is full. Empty the water tank. ¡ Tank full light lights (The unit beeps continuously.) ¡ Air flows stops (louvre stops) ¡ Swing monitor turns off ¡ Compressor turns off • After removing the water and replacing the tank, the Tank full light will go off, and the unit will automatically return to operation mode. • When the Tank full light is lit, no operation but ON/OFF is possible.

5. Technical points 5.1 The technical points of the new products 1) Drying inside During dehumidification, moisture accumulates on the heat exchanger. If left, this can lead to mildew growth, which is circulated around the room with the air discharge. Drying inside starts automatically after operation, and dries any moisture inside the unit. 2) Powerful 16-litre/day dehumidifying The uncomfortable damp feeling caused by humidity is something that needs to be removed quickly.
5.2 Operation and Performance Working temperature Defrosting Dehumidification is possible with a room temperature of 1 – 35°C. If the room temperature exceeds 35°C, however, the temperature inside the unit will increase; therefore, the protective device may activate and halt operation in some cases. For this reason, the louvres should be aimed upward.

6. Maintenance Maintenance Do not use detergents, cleaning agents for heat exchange equipment, abrasive powders, chemically treated dusters, gasoline, benzene, thinners or other solvents, as they can damage the unit or the water tank, which may result in leakage. Cleaning Water tank · Main unit Wipe with a soft cloth. Once every three months Photocatalytic filter Soaking the filter in water, and leaving it to dry in the sun renews the performance and prolongs service life.
Removing Water from the Tank The unit automatically shuts down and lights the Tank full lamp when the tank (approximately 4L) is full. Empty the tank. 1 3 Remove the water tank. Open the front door. Confirm that the lid is securely attached to the water tank, and push the tank in. Close the front door. Grasp handle and slide out. ¡ If the lid is not properly closed, you may have problems removing the tank.
Replacing the Air Purifying Filter The air purifying filter is disposable. Make sure to replace the filter when it becomes dirty. Replacing the photocatalytic filter Although the photocatalytic filter lasts roughly 2 years, replace it when: ¡ You have soaked the filter 8 times. ¡ The photocatalytic filter has turned brown due to cigarette smoke or black with dust. Filter life differs on usage and environmental conditions. Remove the front panel and pre-filter to replace the photocatalytic filter.

10. Continuous Water Drainage Necessary items If a drain is available, the unit can continuously drain excess water by attaching a commercially available hose (internal diameter 15mm). The unit can be operated for extensive periods without the need to empty the water tank. CAUTION ¡Commercially available hose (ID 15mm) Long enough to reach the drain. Do not drain water continuously if there is a possibility that temperatures around the hose could drop below freezing point.

11. Troubleshooting Symptom Cause/Remedy The unit blows warm air ¡ Dehumidified air passes through heating coils causing it to warm (this unit is not a cooler). This is not a malfunction. Water does not collect in the water tank (minimal dehumidifying results) ¡ 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 the amount of water collected).
Cause/Remedy Symptom The unit makes noises The operating noise is loud/reverberates ¡ Check to see if the unit is on a slope or uneven surface. ➝ Move to a sturdy even surface. ¡ Check to see if the pre-filter is clogged. → Clean according to the maintenance procedures ¡ Operating the unit in small rooms or in tight spaces sometimes causes the sound to reverberate. ➝ Place a mat underneath the unit.
Precautions The following diagrams indicate circumstances where danger can result from mishandling the unit. WARNING Mishandling may result in fatal or serious injuries. CAUTION Mishandling may result in injuries or damage to your home or property, etc. Meanings of the graphic symbols used in this manual and on the unit are explained below.
CAUTION Do not cover the front or side air intakes or the air outlet with cloth, curtain, etc. Do not drain water continuously if there is a possibility that temperature around the hose could drop to freezing point. This results in poor ventilation and may cause heat generation/fire. Water inside the hose may freeze and prevent the water in the tank from flowing out. The water may leak from the unit and damage surrounding objects. Do not stand on, sit on or lean against the unit.
Precautions (cont.) CAUTION After emptying the tank, transport the unit by grasping the handle firmly. Losing your footing while carrying the unit may cause personal injury or damage to the floor. When using the continuous drainage outlet, make sure to position the hose so that the water drains without obstruction. The water in the tank may leak and damage surrounding objects. When draining water continuously or left unattended for long periods, inspect the unit every two weeks.
