What is a washable photocatalytic filter? Water tank Tank lid Floating element Front door

Back Handle Raise handle to transport

The washable photocatalytic filter has a two-layer construction consisting of a white particle filter and a blue air-freshener filter. The fine particle filter removes pollen* and dust particles. The special air-freshening agent contained in the fibres of the air-freshener filter absorbs odorants such as ammonia. The odor is broken down by photocatalysis renewing the air-freshening properties. As the filter’s particle and air-freshening properties are renewed by simply soaking and leaving it to dry in the sun, the air purifier can be used continuously over a long time. Cigarette smoke and toxins found in smoke, such as carbon monoxide, cannot be removed with this filter. * Diameter of pollen: approx. 10-100µm

If left, this can lead to mildew growth, which is circulated around the room with the air discharge. discharge. Drying inside starts automatically after operation, and dries any moisture inside the unit. 2) Powerful Powerful 16-litre/ 16-litre/day day dehumi dehumidifyin difying g The uncomfortable damp feeling caused by humidity is something that needs to be removed quickly. Mildew can grow and damage the home or clothing when closets, dressing rooms, shoe cabinets, and other spaces where humidity is prone to collect are not dehumidified. A single high-capacity unit is effective in dehumidifying and drying various locations throughout the home, quickly moving from one point to the next. 3) Room humidity humidity and sensible sensible temperature temperature comfortably comfortably controlled controlled The EASY DEHUMIDIFYING mode controls humidity according to room temperature. If the room temperature rises during dehumidification, use CIRCULATION mode (* 1) to lower the sensible temperature. *1 The automatic dehumidification and blower modes operate alternately controlling the sensible temperature and humidity to a comfortable level (50%–60%). 4) Washable Washable photocatal photocatalytic ytic filter The photocatalytic deodoring filter and particle filter are integrated. This filter collects ammonia, the base for household smells, as well as dust, fungus spores, and pollen. It is easy to clean, meaning longer lasting performance.

5.2 Operation Operation and Performa Performance nce Working 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. • If the room temperatur temperature e is lower than than 1˚C, there is is danger of the removed water freezing, making dehumidification impossible, so the fan will start operating.

The unit may display during operation and stop air flow, followed by a change in the operating noise. The unit has stopped the airflow, and is melting internal frost into the water tank. The unit will resume automatically when the defrost operation completes.

Wait for 3 minutes before dehumidifying

Room temperature may rise 2-4°C during operation

The dehumidifier will not operate for 3 minutes when the unit is turned on immediately after being turned off or plugged in. (In order to protect the compressor.) When dehumidifying begins, the operational noise increases. This is not a malfunction.

The dehumidifier does not have a cooler function. Due to heat produced during operation, the room temperature may rise 2-4°C As a result, the unit may blow warm air, but this is not due to a malfunction. During winter, the air may not feel warm as the temperature is below body temperature.

This operation will be performed automatically when the room temperature is approximately 15°C or lower. (When humidity is high, this will occur approximately once every 40 minutes for 5 – 10 minutes.)

How does the dehumidifier work? If you pour cold water into a cup, the air around it becomes cold, causing water droplets to form on the surface of the cup. The dehumidifier takes advantage of this phenomenon to remove moisture from the air. The unit draws air from the room, cools it with its cooling coil, causing the moisture to transform into water droplets. The water droplets fall into the water tank. 2 The dehumidified air is reheated by the 3 heating coil, and then discharged. The humidity of the room is thus reduced by repeating steps 1 , 2 , and 3 . 1

Dried (warm) air Cooling coil Moist air

Compressor

The humidity reading on the unit may differ from a hygrometer in the same room Even in the same room, temperature and humidity levels may differ from place to place. If the hygrometer and the unit are in different parts of the room, the humidity levels are prone to differ. Moreover, humidity levels differ between places that have good and no airflow. Use the reading on the unit as an estimate.

11. Troubleshooting

Symptom

Cause/Remedy

The unit blows warm air Water does not collect in the water tank (minimal dehumidifying results)

¡

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 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). 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. ¡

The unit does not operate (no air comes out) The unit stops Stops after a short time Louvre does not swing

¡

Check to see if the pre-filter is clogged. ¨ Clean according to the maintenance procedures.

¡

Is the unit operating in LAUNDRY mode? ¨ The unit may stop in one hour if the room temperature is about 5°C or less.

¡

Check to see if the unit is in EASY DEHUMIDIFYING, MILDEW 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. properly. ¡ Check to see if the water tank is inserted properly. ¨ Adjust the position of the water tank. ¡

Lights

The unit continues to operate even though it is turned off

Check to see if the unit is in defrosting mode. mode. The unit activates defrosting mode when the room temperature drops below 15 C. The dehumidifier and blower functions stop during defrosting. °

¡

Is the unit set to internal drying mode? This function activates automatically after ending operations.

Check to see if the room is not too large. boundaries (floor space). ¨ Use within effective boundaries ¡ 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. ¡

The humidity level does not reach the level set The hygrometer reading on the unit differs from other hygrometers in the room

¡

Hygrometer readings differ from place to place even if in the same room. Use the unit humidity reading as an estimate.

The louvre does not move as set

¡

Press the Swing louvre switch again.

The water tank contains liquid or white water residue

¡

The residue is from final product product testing at the factory. It is not a result of a malfunction. malfunction.

¡

The residue is from debris in the air. ¨ Clean according to the maintenance procedures.

There is black residue on the inside of the water tank and lid.

46

Cause/Remedy

Symptom

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. ¡

The operating noise is loud/reverberates

The unit makes noises

The operating sound suddenly increases in volume The wind sound changes in volume

The unit produces a simmering sound The unit buzzes intermittently (or the compressor does not activate) When first used

The unit produces an odour

¡

During internal drying

¡

The sound increases when the compressor activates (3 minutes after turning on the unit or during Easy dehumidifier and Automatic modes).

¡

The volume of the sound differs depending on the angle of the louvre.

¡

This is the sound of the refrigerant. The sound can be heard while the refrigerant stabilizes after the unit turns on, changes modes, or stops.

¡

This is the sound of the compressor. In modes that monitor the humidity level, or during drying inside the compressor operates intermittently causing the sound to be heard occasionally. The compressor does not activate after turning the unit off, or for 3 minutes after plugging the unit into a power socket. (This is to protect the compressor from damage.)

¡

The heat converter heats rapidly causing a brief odour. This is not a malfunction.

¡

The moisture expelled from inside the unit may smell due to odorants* that were not caught by the photocatalytic filter dissolving in the water. This is not a malfunction.
