② Startup conditions
(a) When operation is on while LAUNDRY operations are selected
(b) When LAUNDRY operations are selected by operating the LAUNDRY switch
③ Stopping condition 1
(a) Average humidity and temperature are measured 30 minutes after starting LAUNDRY operations, and every 10
minutes from then on.
(Average humidity and temperature updates are performed at the same time as humidity measurements.
Once every 15 seconds)
(b) A shows the average temperature when the average humidity is 50% or less. (0~39˚C)
(c) B shows the time elapsed until the average humidity is 50% or less after starting LAUNDRY operations. (B 40)
(d) After measuring A and B mentioned above, dehumidifying operations are then performed only for time Y
calculated by the following equation.
NORMAL Stop time Y = Elapsed time B × (1.4 - Temperature A /100)
HEAVY
Stop time Y = Elapsed time B × (1.5 - Temperature A /100)
Example) The shortest stop time is as follows. (When the temperature = 30˚C)
The shortest stop time Y = 40 × (1.4 - 30/100) = 44 minutes
Therefore, the shortest time before stopping after starting LAUNDRY (NORMAL) operations is 84
minutes.
④ Stopping condition 2
(a) After starting LAUNDRY operations X Hours elapsed (Where X is the E2PROM data modification range of
integers form 1 to 12 where 12 is the default)
(b) Stopping condition 2 is applied in the following situations.
- After starting LAUNDRY operations, when humidity does not reach 50% or less after X hours have elapsed
- When B+Y X hours under stopping condition 1
⑤ The time count during tank full detection is as follows.
(a) Before detecting 50% or less for stopping condition 1 : Time count stop
(b) After detecting 50% or less for stopping condition 1
: Time count continues
(c) Stopping condition 2
: Time count stop

8. Technical points
„ The amount of dehumidifying becomes less in winter.
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 only a little water collects in the tank, this is not a malfunction.

Room temperature (°C)
z The values shown on the graph were measured at constant
temperature and humidity and do not reflect values obtained
in actual usage conditions.
„ Points to be aware of
z Room temperature may rise 2-4°C during operation
Unlike an air conditioner, the unit is not capable of cooling a whole room. Using the unit in a closed room will instead cause the
room temperature to rise.
Ԛ
How does the dehumidifier work? <Heat Pump Cycle>
Cool air Warm air
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.
Ԛ
Cooling coil
The dehumidifier takes advantage of this phenomenon to remove moisture from the air.
Cool air
Air in room
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 Air passed through the re-heating coil is heated and blown out from an air outlet.
(The air outlet varies depending on the operating mode.)
The humidity of the room is thus reduced by repeating steps ①, ② and ③.

„ Tips on Drying Laundry
How to Hang Clothes
z Fully extend the clothes to remove any wrinkles.
z Leave space between clothes to allow air to
easily pass through them (Guideline for spacing:
Approximately 5 cm)
z Hang any difficult to dry items in positions where
wind can easily come into contact with them.
Clothes placed close together will take time to dry.
<Drying takes a long time in the following cases>
z When there are a lot of clothes
z When the room temperature is low
The drying time required at a low
temperature (approximately 10°C)
is around twice that at a normal
temperature (approximately 20°C).
z When the room is large
18
How to Blow Air at Clothes
z Use the swing louvre to blow air onto all of the
clothes
Clothes places in locations that are not exposed to
the wind will take time to dry.
z When there are a lot of clothes
Change the hanging positions of the clothes during
drying to ensure air is blown onto all of the clothes.
About the Room for Hanging Clothes
z Hanging the clothes in a small enclosed room
and dehumidifying. It allows for very efficient
dehumidifying and quick drying.
z When the room temperature is low such as
during the winter
Drying becomes
easier if you also use
a heater to raise the
room temperature to
approximately 16°C or
more.

→ The unit is automatically switching dehumidifying, blowing, and stopping.
z Check to see if the silver ion filter is clogged.
→ Clean according to the maintenance procedures.
Stops after
a short time
Indicates
Indicates
24
z Is operation being performed with the unit set to LAUNDRY NORMAL or HEAVY?
→ If the room temperature is approximately 5°C or less, operation stops after
approximately 1 hour. If the room temperature is low, it becomes difficult for
water to evaporate from clothes because the humidity does not change.
z Is operation being performed with the unit set to DEO-DRY?
→ This operation is designed to end after approximately 1 hour.
z Check to see if the water tank is full.
→ Empty the water tank and return it to its original position.
z Check to see if the water tank is inserted properly.
→ Adjust the position of the water tank.
z 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.
The unit continues to operate
even though it is turned off
z Even if the POWER switch is turned off, the blower fan rotates for
approximately 2 minutes to prevent the temperature inside the unit from
rising. Wait until the blower fan stops before removing the power plug.
z Is the unit set to drying inside mode?
This function activates automatically after ending operations.
The humidity level does not
drop easily
z Check to see if the room is not too large.
z Check to see if the exits to the room are open.
→ Refrain from opening doors/windows during operation.
z Check to see if steam producing appliances such as kerosene heaters are on in the vicinity.
The hygrometer reading on
the unit differs from other
hygrometers in the room
z 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
z Press the Swing louvre switch again.
The water tank contains liquid
or white water residue
z The residue is from final product testing at the factory. It is not a result of a
malfunction.
There is black residue on the
inside of the water tank and lid.
z The residue is from debris in the air.
→ Clean according to the maintenance procedures.

Cause/Remedy
z Since the unit uses two fans and two motors in addition to the cool air function, the
operating sound becomes loud compared to models without a cool air function. This is not
a malfunction. If the operating sound bothers you, use the unit set to DEHUMIDIFYING LOW.
z Check to see if the unit is on a slope or uneven surface.
→ Move to a sturdy even surface.
z Check to see if the silver ion filter is clogged.
→ Clean according to the maintenance procedures.
z Operating the unit in small rooms or in tight spaces sometimes causes
the sound to reverberate.
→ Place a mat underneath the unit.
z The sound increases when the compressor activates (approximately 3 minutes
after turning on the unit or during automatic operation ( DEHUMIDIFYING AUTO)).
z Is operation being performed with the unit set to DEHUMIDIFYING LOW?
→ When the room temperature becomes 35°C or more, operation is performed
with the same amount of wind as HIGH in order to protect the compressor.
z The volume of the sound differs depending on the angle of the louvre.
z 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.
z This is the sound of the blowing route changing. The unit sometimes makes
sounds when the operating mode changes or the blowing route changes during
operation.
z 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.)
When first used
z The heat converter heats rapidly causing an odour. This is not a malfunction.
• During internal
drying
• During

WARNING
Do not damage or modify the power
cord or plug. Do not use power sockets
in which the plug fits loosely.
Do not attempt to repair,
disassemble, or modify the unit.
Do not modify, bundle, twist, bend or heat the
power cord. Do not place under objects or use
with the end close to the plug bent.
(Keep pets from biting the cord.)
This may result in fire and/or electric shock.
Refer servicing to your dealer or Mitsubishi
Electric Service Centre.
The cord may be damaged resulting in fire,
electric shock or heat generation.
Do not plug many power cords
into one power socket.
This may result in fire, electric shock or
malfunctions.
Do not start/stop the unit by
plugging/unplugging the power cord.
This may result in fire and/or electric shock.
Do not put the unit near heat-generating
devices (such as stoves, fan heaters, etc.).
Exclusively use 220 to 240 V AC
power sockets for the power supply.
Failing to do so may result in a fire and/or
electric shock.
Wipe dust off the power plug and
insert the plug firmly.
If the plug is not fully inserted into the socket,
dust may gather on the connectors which may
cause fire and/or electric shock.
Should abnormal symptoms occur
(a burning smell, etc.), switch off
the unit and unplug it from the
socket.
The plastic parts may melt and cause fire.

Do not insert your fingers, bar, or
things that burn easily
such as paper into an
air outlet or air intake.
Do not touch the
swing louvre.
Continuing to operate the unit may result in
fire, electric shock, or malfunctions. Contact
your dealer or Mitsubishi Electric Service
Centre for consultation.
There is an internal heater, and such actions
may result in a fire, electric shock, burn, or
malfunction. Also, the internal fan rotates at
high speeds, and such action may result in an
injury or malfunction.
Accidentally drinking the water or using it for
other purposes may cause illness and/or
unforeseen accidents.
Remove water that has collected in
the tank.
CAUTION
Do not cover an air outlet or air intake
with laundry, cloth, curtain, etc.
This results in poor ventilation
and may cause heat
generation/fire.
Do not put vases or any other
objects filled with water on the unit.
Water may leak into the unit adversely
affecting electric insulation and cause
electric shock and/or fire by short-circuiting.
Do not wash the unit with water.
Do not use the unit where it is
likely to come in
contact with water.
Exposure to water may result in fire or electric
shock caused by an electric leak.
Do not use the unit where it may
be exposed to direct sunlight or
other weather conditions.
(This unit is for indoor
use only.)
This may cause overheating, 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.
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 point airflow from the
unit directly at the body for a
prolonged period of time.
Be especially careful when using the unit
where there is someone who is
unable to adjust the humidity
(infant, child, or elderly
person).
If air-flow is directed at the body for long
periods, it may harm one’s physical condition
and lead to dehydration.
Do not stand on, sit on or lean
against the unit. Do not pull the
unit by the air outlet.
As the unit is on wheels, it may move, tip
over, or fall causing personal injury.
Do not remove the Styrofoam
from the floating element.
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
that may be subject to oil or
flammable gas leakage.
Such a leak around the unit may cause
combustion and fire.
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 air may harm the unit and cause
water in the tank to leak, resulting in
damage to property.
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 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.
Keep the continuous drainage lid
out reach of children.
Failing to do so may result in the lid
being accidentally swallowed.

Precautions (cont.)
CAUTION
Install the unit in a location
where the floor is flat and stable.
If the unit falls over, the water collected
in the water tank may leak damaging
surrounding objects and in turn
result in fire or electric shock caused
by an electrical leak.
Before moving the unit always
switch it off, unplug it and
remove water from the water
tank.
Moving the unit with water in its tank
may cause the water to leak and
damage the surrounding objects and
in turn result in electric shock and/or
an electric leak.
After emptying the tank,
transport the unit by grasping
the handle firmly.
Losing your footing while carrying the
unit may cause personal injury or
damage to the floor.
Grasp the plug and remove from
the power socket.
Switch the unit off and unplug
from the power source when
cleaning it.
When the unit is on, the internal fan
rotates at high speeds and may cause
injury.
Unplug the unit from the power
source when not using the unit
for an extended period of time.
Otherwise it may cause fire and/or
electric shock caused by an electric leak.
When draining water
continuously or left unattended
for long periods, inspect the unit
every two weeks.
Do not allow debris to clog the filter/
hose as this may cause overheating/
leakage.
When using the continuous
drainage outlet, make sure to
position the hose so that the
water drains without obstruction.
The water in the tank may leak and
damage surrounding objects.
When removing the plug from the power
socket, do not pull on it diagonally
or by the cord as this may cause the
projections/wiring to be damaged
resulting in a short circuit, electric
shock or fire.
Use the unit with caution in
rooms where the walls, furniture
and art work are vulnerable to
dry air, as it may cause cracks
and warping.
