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. Floating element Do not remove or dismantle. Do not remove the louvre front door. ¡ The unit draws in dust present in the air, and this may cause the tank to gradually become dirty.
Replacing the Air Purifying Filter The air purifying filter is disposable. Make sure to replace the filter when it becomes dirty. (The filter cannot be washed or reused.) When to replace it Replace the filter when it becomes dirty (brownish) with cigarette smoke, dust, etc. Generally, one filter should last about 6 months. (This will depend on usage conditions.

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. ¡Commercially available hose (ID 15mm) CAUTION Long enough to reach the drain. ¡Pincers Do not drain water continuously if there is a possibility that temperatures around the hose could drop below freezing point.

11. Troubleshooting ¡ For the symptoms listed below, refer to the remedies listed right. 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.
Symptom The unit makes noises Cause/Remedy 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. This results in poor ventilation and may cause heat generation/fire. Do not stand on, sit on or lean against the unit. The unit may tip over causing injury. Do not drain water continuously if there is a possibility that temperature around the hose could drop to freezing point. Water inside the hose may freeze and prevent the water in the tank from flowing out.
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.
