What is a washable photocatalytic filter?

The washable photocatalytic filter has a two-layer construction consisting of a white particle filter and a blue air-freshener filter. <Particle filter>

The fine particle filter removes pollen* and dust particles.

<Air-freshener Filter>

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

Information

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. 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 and sensible temperature comfortably 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. *1The automatic dehumidification and blower modes operate alternately controlling the sensible

temperature and humidity to a comfortable level (50%–60%).

4) Washable photocatalytic 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 and Performance

CURRENT

Working temperature

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 temperature is lower than 1˚C, there is danger of the removed water freezing, making dehumidification impossible, so the fan will start operating.

Wait for 3 minutes before dehumidifying

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.

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.

1 The unit draws air from the room, cools it with

its cooling coil, causing the moisture to transform into water droplets.

2 The water droplets fall into the water tank. 3 The dehumidified air is reheated by the

heating coil, and then discharged.

The humidity of the room is thus reduced by repeating steps 1, 2, and 3.

Defrosting

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.

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.)

Room temperature may rise 2-4°C during operation

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.

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.

<Cause>

● Inconsistencies in temperature and humidity

● Difference in location

● Difference in hygrometer precision

5.4 Performance curve When the temperature and humidity are low, the amount of water collected is

decreased.

In winter, because the temperature is lower than in summer, the effects of the dehumidifier decrease dramatically as shown in the graph below. Although less water collects in the tank, this is not a malfunction.

* If the temperature is low, but the humidity is high due to snow or rain, operating the unit in LOW TEMP

mode will yield better results than in LOW mode.
