Room temperature may rise 3-6°C during operation.
The dehumidifier does not have a cooler function. Due to heat produced during operation, the room temperature may rise
3-6°C. As a result, the unit may blow warm air, but this is not due to a malfunction. (During winter, the air may not feel warm
as the temperature is below body temperature.)
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 airflow. 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 over 40°C, the unit will operate in blower mode without dehumidifying.
If the temperature is below 1°C, the extracted water is close to freezing disabling the dehumidification, and only the
blower is operating.
The amount of dehumidifying becomes less when the humidity
becomes approximately 40% or less or the room temperature becomes
approximately 35°C or more.
If the humidity becomes approximately 40% or less or the room temperature becomes approximately 35°C or more, the
amount of dehumidifying becomes less because operation is performed with the power consumption of the heater reduced
to a level equivalent to that of LOW mode.
The blown air may cause smell during operation.
An odor may be emitted from the parts inside the dehumidifier when you first use the dehumidifier.
Odorants that cannot be removed by the silver ion filter may be absorbed by the dehumidifier rotor inside the unit.
Odors unique to zeolite (sour smell, burning smell, etc.) may be emitted from the dehumidifier rotor. These odors have
no effect on humans and animals.
If the room contains any of the following items, the corresponding odor will be absorbed by the dehumidifier rotor inside
the dehumidifier. Also, that absorbed odor will be heated by the heater, which may result in a burning like smell or other
abnormal odor.
Examples: Cigarettes, cosmetics, hair dressing products, building materials, new furniture, etc.
Absorption of moisture
Discharge of moisture
How does dehumidification work?
① Air is drawn from the room, moisture is absorbed
by the dehumidifier rotor, and dry air is blown
out.
②
The dehumidifier rotor is heated with a heater,
and the absorbed moisture is discharged inside
the heat exchanger.
③ The discharged moisture is cooled by the heat
exchanger, causing it to transform into droplets,
which is collected in the water tank.
