Dust Sensor · Humidity Sensor; Auto Detection - Hitachi EP-A6000 Instruction Manual

Dust sensor is capable of sensing the dusts in the air such as cigarette smoke, house
dust, pollen, etc.
Dust sensor may fail to sense the dusts stirred up when you lay out or put away the
bedding, which are signifi cantly fewer contaminants than cigarette smoke, etc. In
such a case, the displayed air contamination level may appear to be lower.
Carry out the periodical cleaning every 3-6 months. Otherwise poor performance of
the dust sensor will result.
The humidity sensor fi nds the humidity of room air during operation.
Humidity level should be taken as a guide only.
The indication may differ from hygrometer reading.
Humidity will change as temperature changes.
Humidity level may differ between well-ventilated and ill-ventilated places.
The air purifi er performs automatic operation by detecting room air contamination with "Odor Sensor" and
room air humidity with "Humidity Sensor".
In the fi rst 3 minutes after the power cord is plugged in, the unit will check room air condition and save it
in memory. During the time, the "Air Sensor" indicator and "Humidity Level 50" indicator will blink. After
3 minutes, both the "Air Sensor" and "Humidity Level 50" indicators will go off and the purifi er is now
ready to operate.
You may start the operation in less than 3 minutes after plugging the power cord.
In this case too, the "Air Sensor" and "Humidity Level 50" indicators will continue to blink, meaning the
unit is checking room air condition. After 3 minutes, the indicators will show your room air conditions.
If you plug in the power cord under contaminated air condition, the sensor sensitivity may be reduced. In such a
case, perform High or Max operation. Or you may try to make the room air cleaner by opening a window before
plugging the power cord. If the sensor sensitivity remains low after this, change the sensor sensitivity setting.
