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. 10-100 m

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.

*1 The 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

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 temperature is lower than 1˚C, there 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.

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.)

Wait for 3 minutes before dehumidifying

Room temperature may rise 2-4°C during operation

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.

1The 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.

3The 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.

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.

	Dried (warm) air

Compressor	Water tank

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.

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.

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.

¡The unit draws in dust present in the air, and this may cause the tank to gradually become dirty. If the dirt does not come off easily, wash with cold or warm water, then wipe with a soft, dry cloth.

¡Mildew may form in the tank unless kept clean.

Once every two weeks

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. Perform this every three months.

1 Remove the front panel and pre-filter.

2 Remove the photocatalytic filter.

3 Soak the photocatalytic filter in water.

Soak in cool to lukewarm water for 30 minutes.

Do not use detergent or hot water. Also, do not brush or rub while soaking as this may damage the filter.

Pre-filter

Debris clogging the pre-filter reduces the effectiveness of the dehumidifier. Clean once every 2 weeks.

¡Stains may remain on the filter, but should not affect performance.

¡The filter can be soaked for a total of eight times. After that, replace with a new filter.

1 Remove the front panel and pre-filter.

2 Remove the photocatalytic filter.

3 Clean the pre-filter.

Remove grit with vacuum cleaner

Hose with lukewarm water when excessively soiled. Dry well.

4 Dry the photocatalytic filter.

Dry well in the sun (The performance of the filter renews with soaking, and the photocatalytic effect of the sunlight removes remaining odorants)

Do not hang with pegs as this may damage the filter.

Do not use the filter while wet.

4 Fit the photocatalytic filter.

5 Attach the pre-filter and front panel.

5 Fit the photocatalytic filter.

6 Attach the pre-filter and front panel.

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 Remove the water tank.

Open the front door. Grasp handle and slide out.

<Hold the tank this way>

2 Remove the tank lid, and empty.

Floating element

Tank lid Do not remove or dismantle the float.

3 Reattach the tank lid and replace the water tank.

Confirm that the lid is securely

attached to the water tank, and

push the tank in. Close the front door.

¡If the lid is not properly closed, you may have problems removing the tank.

¡If the tank is not installed correctly, the tank full light will come on, and the unit will not operate.

Note	Do not remove or dismantle the floating element
	in the tank. If it is removed, the unit cannot detect
	when the tank is full, and this could result in
	leakage.

Pour the water out as shown.

15

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.
