∞
Empty the water tank before operating the unit. The unit may stop before the clothes are dry due to a full tank.
∞Do not use in conjunction with OFF Timer mode. The unit may stop before the clothes are dry.
∞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.
∞When the room temperature is below 5°C, less water evaporates from the
clothes, decreasing the amount of temperature change. Therefore the unit is
unable to detect the state of the laundry and may turn off after 1 hour.
∞Restart the unit if it turns off before the laundry dries (except when the temperature is
below 5°C).

Current Level of Humidity
The current humidity indicated by the dehumidifier may sometimes
differ from the humidity indicated by an ordinary hygrometer but this is
not a malfunction.
1. If the air temperature at the location where the dehumidifier is
installed and the place where the hygrometer is located differ, the
relative humidity will also differ.
2. The flow of air (ventilation) also affects the humidity, which may
differ for objects around the periphery and depending on the
installation location, etc.
This dehumidifier has no cooler function. In fact it emits
some heat causing the room temperature to rise by 2 to
4°C. The unit may produce warm air, but this is not due to
a malfunction.
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.
The size of a room that can be dehumidified differs depending on the house structure and room style, etc.

What is relative humidity?
Relative humidity is the mass of
water vapor present in the air
expressed as a percentage of
the mass that would be present
in an equal volume of saturated
air (100%) at the same
temperature. The dehumidifier
and an ordinary hygrometer
indicate this relative humidity.
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.
2The 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.

Wait for 3 minutes before dehumidifying
Room size guide

Heating during operation
4.2 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.

4.4 Performance curve
Relationship between dehumidification and room temperature/humidity
The lower the temperature and humidity, the smaller the quantity of dehumidifying as shown on the graph.
•The dehumidification quantities shown on the graph were measured at constant temperature and humidity, and do
not reflect actual usage conditions.
•In winter, the air is so dry that dehumidification is almost impossible.
•Operation in low temperatures
Operating the LOW TEMPERATURE mode produces greater dehumidification than when on HIGH for
days when the temperature is low, but humidity is high due to snow or rain.

turns the power source to OFF.
<Current setting: 2A>
(2) Motor protector................Current flow exceeding 1.7A with compressor surface temperature of approx.
(Overload relay)..............100°C shuts down compressor operation.
The compressor will also shut down when malfunctions or other problems
cause the current flow to exceed 4.7A.
(3) Control circuitry ...............The room temperature thermister senses temperature below about 0°C, and
shuts down the compressor.
(4) Thermal fuse ...................When blower motor temperature exceeds 134°C due to blower locking or other
malfunctions, blower operation shuts down.

4Mildew Guard mode
(a) Alternately activates/deactivates compressor or blower according to current humidity/time. (Fan rank is as shown in 2)
(b) Operates dehumidifier when Mildew guard mode is activated or every 24 hours after activation.
(c) Dehumidifier is deactivated when the following parameters are breached. (Compressor and blower stop)
•2hours of below 40% elapses and below 35% is detected.
•4hours of below 50% elapses and below 45% is detected.
*However, if the humidity rises above the given levels for more than 3 minutes, the accumulated time returns to zero.
(d) If the humidity rises to 75% after deactivation, the dehumidifier automatically operates until the humidity is brought down to 65%.
(e) If 24 hours elapse from the time the unit was turned on, all accumulated time counts for all humidity levels are reset.

1Humidity set operation
(a) Compressor and blower fan operation will switch by current humidity and set temperature.
2Specifications shared at all operation modes
(a) Dehumidifying will not start for about 2 seconds when turning the operation power on with the swing stopped. (However, humidifying
will begin immediately when pressing the swing louvre switch within 2 seconds of turning the power on.)
(b) The compressor and blower fan will operate for about 7 minutes after turning on the operation switch or activating the compressor,
regardless of humidity or temperature levels.

5Easy Dehumidifier
(a) Modifies humidity setting or operates CIRCULATE mode (blower only mode) according to the room temperature.
(b) Switches temperature table every 60 seconds to prevent the blower from turning on and off at the 3-minute restart for the coloured
section in the chart below. (51% – 59%)
(c) When the room temperature is above 29°C (temperature rising) or 27°C (temperature decreasing), CIRCULATE mode operates with the
humidity below 50%. The unit activates the dehumidifier when the humidity rises above 60%, and returns to CIRCULATE mode when
the humidity drops below 50%.
