    Drying laundry indoors

    Use the dehumidifier in

    a small, enclosed room.

    Maintain room temperature above 16°C

    with a heater

    Installing your dehumidifier

    Make sure to leave some space around the

    unit.

    Operating noise

    Place the unit on top of a mat. This reduces

    vibration and noise. It also prevents leaving

    depressions on carpets.

    ¡Space laundry to improve airflow.

    ¡ Drying times will vary depending on the nature of the

    laundry and the room temperature.

    ¡ The airflow is strongest to the top right of the unit.

  • The water tank may contain water

    residue at time of purchase. This is

    from final product testing at the

    factory and is not due to a defect.

    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 dorants such as ammonia. The odor is broken down by

    photocatalysis renewing the airfreshening 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.

    ¡ 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.

    When the temperature is low, condensation may still form on windows exposed to the outside

    air even when LOW TEMP mode is operating

    ¡

    MILDEW GUARD

    The unit lowers humidity levels automatically once a day, suppressing mildew growth.

    ¡ The unit operates intermittently for 2-4 hours a day

    (24 hours).

    ¡ The operating time varies depending on the humidity.

    The unit continues to operate when the humidity does not

    decrease.

    • Humidity 40%→Approx. 2 hours

    • Humidity 50%→Approx. 4 hours

    ∞ Refrain from turning on ventilation fans or opening windows or doors as this lowers performance.

    ∞ Mildew growth may still occur due to the fungus type and conditions of the room.

    • E.g. Rooms that contain excessive condensation, bathrooms, and places with bad airflow (insides of

    closets and behind furniture).

    ∞ This mode does not remove existing mildew.

    ∞Do not use in conjunction with OFF Timer mode. Effects may not be achieved.

    How is mildew Mildew is unable to produce new spores (similar to plant seeds) if dried as

    mycelia. The Mildew Guard feature applies this principle (However, the

    growth suppressed?

    spores themselves are resilient to dry conditions.).

    ¡ EASY DEHUMIDIFYING

    The unit operates 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.

    The airflow or louvre operation may stop

    according to the humidity level.

    ¡ LAUNDRY

    The unit operates for 12 hours and automatically

    switches off.

    ∞ Drain the tank before use.

    The unit may stop before the washing dries

    because of a full tank.

    ∞ Do not use in conjunction with the OFF

    timer.

    The timer may turn the unit off before the

    washing dries.

    ∞ The following conditions prevent clothes

    from drying well:

    Room temperature below 15°C, large

    volume of laundry; laundry not spaced well;

    clothes of thick fabric and spacious room.

    The louvre swings from the UPWARD position

    through to the REAR position in order to send

    air to all corners of the room.

    The louvre stops in a vertical position. The swing

    monitor turns off.

    To change the louvre to a desired angle, wait

    until the louvre stops, then adjust by hand.

    The louvre moves slowly through the

    last 30° of the swing, as the time

    taken to traverse the rear arc is

    shorter than that for the upward arc

    when moving at a constant speed.

    The swing function is not available.

    Adjust the angle manually (from

    three possible positions).

    When using the low air outlet, do not close

    the louvre, as it needs to open slightly to

    make directional adjustments.

    Move the louvre

    from the sides.

    Depending on the angle of the louvre, some air

    may blow out of the low air outlet.

    5. Technical points

    5.1 The technical points of the new products

    1) Internal drying

    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. Internal drying starts automatically

    after operation, and dries any moisture inside the unit.

    2) Powerful 26-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.

  • 10

    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 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.

    Working temperature

    Wait for 3 minutes before dehumidifying

    Defrosting

    Room temperature may rise 2-4°C during operation

    5.2 Operation and Performance

    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.)

    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.

    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.

    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 effect of the dehumidifier is greatly

    reduced as shown in the graph below.

    Although less water collects in the tank, this is not a malfunction.

    Summer (humidity)

    Winter (dampness)

    * 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 HIGH mode.

    ¡ The values shown on the graph were measured at

    constant temperature and humidity and do not

    reflect values obtained in actual usage conditions.

    1.

    Outline of Control

    (a) Lowering the temperature once a day ‘suppresses’ mildew growth.

    (b)

    The dehumidification time changes depending on how much the temperature was lowered (40%: 2 hours, 50%: 4 hours).

    2. Under the following conditions, mildew guard will clear the time count and restart with initial settings.

    Mildew guard starts with dehumidifier operations by turning ON the compressor and fan regardless of the present

    humidity or time.

    (a)

    The power is turned ON when mildew guard is selected (i.e.: power button is turned ON or ON timer time is reached).

    (b) Mildew guard is selected with the MODE button.

    (c) Mildew guard is reactivated by operating the air purifier button (Air purifier ON → OFF).

    (d) Mildew guard is run for 24 hours.

    3. While mildew guard is operating, the dehumidifier is deactivated under the following conditions.

    (a) Current humidity below 35% detected followed by 2 hours of below 40%.

    However, the accumulated time is cleared if the current humidity breaches 41% for 3 consecutive minutes during the count.

    (b) Current humidity below 45% detected followed by 4 hours of below 50%.

    However, the accumulated time is cleared if the current humidity breaches 51% for 3 consecutive minutes during the count.

    4. After being deactivated in step 3, if the humidity level reaches 71%, the dehumidifier is automatically activated and runs

    until the level drops below 65%. Below 65%, the dehumidifier remains deactivated until the humidity level again reaches

    71% (limiter dehumidifier operation).

    5. Mildew guard mode is disabled in the following cases.

    (a) The mode button is used to activate Low Temp mode.

    (b) The selection button is used to activate the previously set mode (EASY DEHUMIDIFYING/LAUNDRY).

    (c) The air purifier button is used to activate AIR PURIFIER mode

    6 Internal drying

    1. Controls

    (a) Prevents the growth of mildew by drying the moisture accumulated on the heat exchanger when the dehumidifier is

    OFF.

    (b) Internal drying operation does not depend on having a full water level.

    (c) The following operations are performed during internal drying operation.

    2. Start conditions for internal drying operations

    (a) Automatic internal drying mode - This mode starts when the Mildew guard elite button is set to ON, and any of the

    following conditions are met.

    • The Power button is turned OFF.

    • The OFF timer time is reached.

    • The LAUNDRY mode completes operations.

    (b) Manual internal drying mode - This mode starts when the Mildew guard elite button is operated while the following

    condition is met.

    • The Power button is turned OFF.

    3. Operating details

    (a) The following indications are displayed during Internal drying operation

    • LED indicator: Only mildew guard elite lamp flashes, others off

    • LCD panel: All off

    (b)Internal drying operates according to the following steps

    • Step 1: Moisture is allowed to drip from the heat exchanger. The louvre is positioned upwards at 90˚.

    • Step 2: Moisture on the heat exchanger is dried with air.

    • Step 3: Moisture on the heat exchanger is dried with heat.

    • Step 4: The heat exchanger is cooled if the temperature rises too high.

    • Step 5: Internal humidity is discharged in Step 4, and the louvre moves to the closed position.

    (c) Step 3 does not perform the tube temperature or room temperature check that accompanies a microprocessor reset,

    and jumps directly to Step 5.

    (d) Mechanisms operated in the above steps (* are deemed EEPROM data.)

    (e) Internal drying operation does not stop even if tank full is detected.

    Recheck Steps 3 to 5

    No problem

    *If error indicators are lit, see Error Indications

    and Corrective Actions on page 29.

    Replace board

    * If the customer complains that the unit won’t dehumidify, make the following checks before starting to repair the coolant

    circuit:

    1 Clogged filter, or dust: ➞ Action: Clean.

    2 Low-temperature, low-humidity operating environment:

    ➞ Action: See the explanation of the graph on page 11, or move the unit to a kitchen or bathroom and request

    verification of its performance.

    3 Request checking whether the unit is in an automatically-stopping operation mode such as “AUTO” or “EASY

    DEHUMIDIFYING”, etc.

    ➞ Action: Verify to dehumidify in “HIGH” operation mode. (See pages 5 – 7.)

    11. Troubleshooting

    Symptom

    Cause/Remedy

    The unit blows warm air

    Water does not collect in

    the water tank (minimal

    dehumidifying results)

    The unit does not operate

    (no air comes out)

    The unit stops

    The humidity level does

    not reach the level set

    The unit continues to operate

    even though it is turned off

    The hygrometer reading on

    the unit differs from other

    hygrometers in the room

    The louvre does not move as set

    The water tank contains

    liquid or white water residue

    There is black residue on the

    inside of the water tank and lid.

    Louvre does

    not swing

    Stops after a

    short time

    ¡ 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 is low.

    Low room temperature/humidity reduces dehumidifying

    effectiveness.

    ¡ 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.

    ¡ Check to see if the unit is in EASY DEHUMIDIFYING,

    MILDEWGUARD, or AUTO.

    ➝ The unit is automatically controlling the dehumidifier, fan, and

    standby times.

    ¡ Check to see if the pre-filter is clogged.

    ➝ Clean according to the maintenance procedures.

    ¡ Check to see if the water tank is full.

    ➝ Empty the water tank and return it to its original position.

    ¡ Check to see if the water tank is inserted properly.

    ➝ Adjust the position of the water tank.

    ¡ Is the unit set to internal drying mode?

    This function activates automatically after ending operations.

    ¡ Check to see if the unit is in defrosting mode.

    The unit activates defrosting mode when the room temperature

    drops below 15°C. The dehumidifier and blower functions stop

    during defrosting.

    ¡ Check to see if the room is not too large.

    ¡ 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.

    ¡ Hygrometer readings differ from place to place even if in the

    same room. Use the unit humidity reading as an estimate.

    ¡ Press the Swing louvre switch again.

    ¡ The residue is from final product testing at the factory. It is not a

    result of a malfunction.

    ¡ The residue is from debris in the air.

    ➝ Clean according to the maintenance procedures.

    Symptom

    Cause/Remedy

    ¡ 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 unit

    makes

    noises

    The operating

    noise is

    loud/reverberates

    The operating

    sound suddenly

    increases in volume

    The wind sound

    changes in volume

    The unit

    produces a

    simmering sound

    intermittently (or

    the compressor

    does not activate)

    The unit

    produces

    an odour

    When first

    used

    During

    internal

    drying

    ¡ The sound increases when the compressor activates (3 minutes

    after turning on the unit or during Easy dehumidifying 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.

    electric shock and/or fire

    caused by an electric leak.

    Do not use the unit in narrow,

    enclosed places such as inside

    closets, between

    pieces of furniture, etc.

    This results in poor

    ventilation and may cause

    heat generation and/or fire.

    Do not use combustion appliances

    in the path of the

    air outlet.

    This may cause

    incomplete combustion

    in the appliance.

    Do not use the unit in places where

    chemicals are used (such as

    hospitals, factories, laboratories or

    beauty salons).

    Chemicals and solvents evaporated in the

    Do not use the unit for special

    purposes, such as preservation of

    food, art or scientific

    works.

    This may negatively affect

    the quality of the items stored.

    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.

    The water may leak from the unit and damage

    surrounding objects.

    Do not use the unit in places

    that may be subject to oil or

    flammable gas leakage.

    Such a leak around the unit may cause

    combustion and fire.

    Do not remove the

    Styrofoam from the

    floating element.

    The floating element will not

    be able to detect a full tank

    resulting in water leakage, which may

    damage surrounding objects or cause

    electric shock and/or an electric leak.

    Do not wash the unit

    with water. Do not

    use the unit where it
