Installing your dehumidifier
Refrain from opening doors/windows during operation
Make sure to leave some space around the unit. At least Stop the louvre in the vertical position. Blowing air 20 cm at the wall may cause staining.
Drying laundry indoors Direct the louvres at the laundry. Space laundry to improve airflow.

Place the unit on top of a mat. This reduces vibration and noise. It also prevents leaving depressions on carpets.
Maintain room temperature above 16°C with an air conditioner ¡ Drying times will vary depending on the nature of the laundry and the room temperature. In low temperatures, drying takes about twice as long as normal. In low temperatures (10°C), drying takes about twice as long as when normal (20°C+). ¡ The airflow is strongest to the top right of the unit.

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

Low Temperature Indicator
The indicator comes on if the room temperature drops below 15°C. Activating Low Temp mode is recommended. DEFROST Indicator
Airflow (dehumidifying) will stop and the frost that has accumulated inside will be melted and dropped into the tank when the indicator is on. Please wait a moment as operation will resume in around 5 minutes. While in DEFROST mode, airflow (dehumidifying) (dehumidifying) and the louvre will stop. The sounds coming from the unit will also change. DEFROST will start automatically when room temperature drops below 15°C (This may be as often as once every 40 minutes).
High humidity warning
The indicator flashes when the humidity in the room exceeds 75%. Activating the dehumidifier is recommended when the indicator is flashing. If the High humidity warning is not used, remove the power plug from the power socket.

Modes ¡
EASY DEHUMIDIFYING
¡
The unit operates intermittently 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.
LAUNDRY
The unit operates for 12 hours and automatically switches off.
The airflow or louvre operation may stop according to the humidity level. 60
y ) t i %50 d ( i l m e u v 0 e H l

Room temperature is below 27°C - the unit automatically sets the humidity level according to the temperature.
¡
LOW LOW
27 30 30
e r u t a r e m p o ) C o m e ( R t °
Room temperature is above 27°C - the unit lowers the humidity level to 50%, then activates the blower. The dehumidifier is reactivated when humidity rises to 60%.
∞ Drain the tank before use.
The unit may stop before the washing dries because of a full tank. n∞ Do not use in conjunction with the OFF o i t timer. a The timer may turn the unit off before the m r washing dries. o f ∞ The following conditions prevent clothes n I from drying well: Room temperature below 15°C, large volume of laundry; laundry not spaced well; clothes of thick fabric and spacious room.
The dehumidifier operates regardless of the humidity level. Airflow is weak.
MILDEW GUARD
¡
The unit lowers humidity levels automatically once a day, suppressing mildew growth. Use the unit within the effective floor space for maximum benefits. ¡ The unit operates intermittently for 2-4 hours a day (24 hours). ON 24 hours 24 hours ¡ The operating time varies depending on the humidity. The unit continues to operate when the humidity does not Standby Standby Repeat decrease. • Humidi Humidity ty 40% 40%!Approx. 2 hours Dehumidifies Dehumidifies • Humidi Humidity ty 50% 50%!Approx. 4 hours
n ∞ Refrain from turning on ventilation fans or opening windows or doors as this lowers performance. o ∞ Mildew growth may still occur due to the fungus type and conditions of the room. i t a E.g. Rooms that contain excessive condensation, bathrooms, and places with bad airflow (insides of m closets and behind furniture). r o f ∞ n This mode does not remove existing mildew. I ∞ Do not use in conjunction with OFF Timer mode. Effects may not be achieved. ¡
LOW TEMP
The unit operates continuously and automatically by controlling airflow according to room temperature. The air flow is strongest below 15 °C. The use of LOW TEMP mode is recommended when the Low temperature indicator is lit.
Information When the temperature is low, condensation may still form on windows exposed to the outside air even when LOW TEMP mode is operating
How is mildew growth
6
Mildew is unable to produce new spores (similar to plant seeds) if dried as mycelia. The Mildew Guard feature applies this principle (However, the suppressed? spores themselves are resilient to dry conditions.). “Identification of Aspergillus and Penicillium”
¡
AUTO
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. n o i t a m r o f n I
Frequent use of exits and room size/conditions may cause the humidity to not reach the set level.
¡
AIR PURIFIER
¡ Pressing the button once displays the set humidify level with the indicator. After 3 seconds, the display Press returns to the current humidity display. ¡
Press again
Pressing HUMIDITY SELECTION while is displayed sets the humidity level. Each time the button is pressed, the humidity setting changes. 70

The unit cleans the air by passing it through the photocatalytic filter. The dehumidifying function function is disabled. n ∞ o i t a m r ∞ o f n I
¡
The air passes through the photocatalytic filter in all modes, cleaning the air even if the air purifier lamp is not lit. Cigarette smoke and toxins found in smoke, such as carbon monoxide, cannot be removed with this filter.
Swing louvre function (how to read the swing monitor)
The louvre can be made to swing. Select from the 4 possible settings to suit the purpose.

This indicates the range of louvre swing. (The louvre and monitor do not move in synchronization.) n o i t a m r o f n I
∞ The level of noise emitted from the unit varies according to the angle of the air-flow. ∞ The louvre may stop up to a maximum of 8 seconds to correct its position, after which it will start
moving again. ∞ If the louvre is knocked out of the desired angle, readjust by following the above steps.
e Stop the louvre in the vertical position when using the unit against a wall. Blowing air at the wall may t o N cause staining.
