Vibration Sensor; Auto Detection; Adjusting Sensor Sensitivity Setting - Hitachi EP-A9000 Instruction Manual

Vibration Sensor

 The sensor detects a fall and impact on the unit. (Installed inside the unit)
 The operation may stop due to tilting of the unit, strong vibrations or impact of a collision.
When the operation stops, "

Auto Detection

 The air purifi er performs automatic operation by detecting room air contamination using the "Odor Sensor" and "Dust
Sensor", and room air temperature and humidity using the "Temperature / Humidity Sensor".
During the fi rst 3 minutes after the power is turned on, the unit will check the air condition of the room.
 The purifi er operates even while it checks the air condition of the room.
During this time, the "Air Sensor" fl ashes green.
 After checking the air condition, the "Air Sensor" will display the room air contamination using the "Odor Sensor"
and the "Dust Sensor".
 If you plug in the power cord in an environment containing contaminated air, the sensitivity of the sensor may be
reduced.
To clean the air of the room, operate in "High" or "Max". Or open a window and unplug the power cord from the AC
outlet when ambient air is clean and plug it back in after 10 minutes.
Adjusting Sensory Sensitivity Setting
 Sensitivity of the "Odor Sensor" and "Dust Sensor" which performs automatic switching of airfl ow rate can be ad-
justed in 3-step fashion.
You can adjust the sensor sensitivity setting as desired.
 The "Odor Sensor" and "Dust Sensor" are similarly adjusted.
