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.
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 .

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.
