Frequently Asked Questions
Why does the dehumidifier seem
to collect less water in winter?
A.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.
E
LOW
The dehumidifier
operates regardless
of the humidity level.
REAR

AIR PURIFIER
The unit operates the air
purifier only.
Any swing setting
Turn the

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 LOW
mode.

not touch the swing
louvre.
Do not put the unit near heatgenerating devices (such as stoves,
fan heaters, etc.).
The plastic parts may melt and cause fire.
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.
Use 220V AC power sockets.
Connecting to power sockets other than
220V AC may result in fire and/or electric
shock.
Remove water that has collected
in the tank.
Accidentally drinking the water or using it for
other purposes may cause illness and/or
unforeseen accidents.
4
The internal fan rotates at high speeds, and
such actions may result in injury or
malfunctions.
Do not attempt to repair,
disassemble, or modify the unit.
This may result in fire and/or electric shock.
Refer servicing to your dealer or Mitsubishi
Electric Service Centre.
Should abnormal symptoms occur (a
burning smell, etc.), switch off the unit
and unplug it from the socket.
Continuing to operate the unit may result in
fire, electric shock, or malfunctions.
Contact your dealer or Mitsubishi Electric
Service Centre for consultation.
CAUTION
Do not cover the front or side air
intakes or the air outlet
with cloth, curtain, etc.
This results in poor ventilation and
may cause heat generation/fire.
Do not stand on, sit on or lean
against the unit.
The unit may tip over causing injury.
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 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.
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
air may harm the unit and cause water in the
tank to leak, resulting in damage to property.
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 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
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 point air-flow from the unit
directly at the body .
If air-flow is directed at
the body for long
periods, it may harm
one’s physical
condition and lead to
dehydration.
Keep the supplement cartridge
out reach of children.
Do not disassemble or tear the bag
inside the cartridge.
Make sure children do not swallow the
contents.
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.
Grasp the plug and
remove from the
power socket.
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.
E
Before using the unit
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.
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.
5
Precautions (cont.)
CAUTION
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.
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 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 over-
heating/leakage.
Tips on dehumidifying
Drain the water tank before use
Refrain from opening
doors/windows during operation
Drying laundry indoors
¡Direct the louvres at the laundry.
¡Space laundry to improve airflow.
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.
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.
Use the dehumidifier in
a small, enclosed room.
Maintain room temperature above 16°C
with a heater
¡ 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.
Installing your dehumidifier
Make sure to leave some
space around the unit.
<For use in close proximity to
a wall>
Stop the louvre in the
vertical position. Blowing
air at the wall may cause
staining.

A special deodorant and anti-bacterial agent (antiallergen, anti-virus and sterilization) are contained in
the fibres of the silver ion filter.
Supplement cartridge
Supplied with unit. Set before use.
What is supplement air?
Recognizing the antioxidant qualities of natural herbs,
we put the oil extracted from rosemary, which has
exceptional antioxidant qualities, into the air outlet
cartridge. The fragrance is so slight that it can be hardly
noticed.
The reason washing yellows is because colourless
organic material trapped within the fibres is oxidized by
heat from a drier or the sun’s UV rays. By using the
dehumidifier and drying your washing indoors, you can
keep away the oxidizing effects of heat and UV rays, as
well as benefit from rosemary’s antioxidant properties,
preventing your clothes from yellowing.
Before using 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.
