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.
z
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 airfl ow.
Use the reading on the unit as an estimate.
z
The unit can operate in a room
temperature range of 1-35°C.
However, if the room temperature exceeds 35°C, the unit
may operate in blower mode or increase the airfl ow. This is
because the temperature within the unit rises causing the
protection mechanism to operate. In order to lower the internal
temperature of the unit, use the unit with the swing stopped
and louvre vertical.
If the temperature is below 1°C, the extracted water is close
to freezing disabling the dehumidifi er, and only the blower
is operational.
z
The defrosting operation is
performed when the room
temperature falls to 15°C or less
In all modes, the defrosting operation is performed
automatically when the room temperature falls to 15°C or less.
Approximately once every 40 minutes at its most frequent,
the DEFROST lamp lights and airfl ow (dehumidifying) stops
automatically, and then the frost that has accumulated inside
the unit will be melted and dropped into the tank.
Please wait a moment as operation will resume in around 5 minutes.
z
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 dehumidifi er is greatly reduced as shown in
the graph below.
Although only a little water collects in the tank, this is not a
malfunction.

How does the dehumidifi er work?
<Heat Pump Cycle>
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 dehumidifi er 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
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
