During Cleaning / Place of Use
During cleaning, lay a soft cloth on
the fl oor and place the purifi er and
detached components (panel and
the like) on it.
In the first 3 minutes after the power cord is plugged
in, the unit checks the room air condition and saves it
in memory. During the checking period, the “Air Purify”
indicator blinks green. After 3 minutes pass, the blinking
stops and the indicator goes out.
You may start the operation within 3 minutes of plugging
in the unit. In this case too, the “Air Purify” indicator
continuously blinks and, after 3 minutes have passed,
the indicator stops blinking and lights up solidly.

Air Purify
Odor
Pollen
This is a normal operation mode.
The odor sensor detects the degree of air contamination, and airflow rate is switched automatically.
This mode is recommended when you have concerns about room odor.
The odor sensor detects the degree of air contamination and switches to “MAX” operation quicker than when
the unit operates in the “Air Purify” mode.
This mode is recommended when you have concerns about pollen contamination.
The operation with Medium airflow is continued for 20 minutes. Then, the odor sensor detects the degree of air
contamination and automatic operation (at “Silent” or “Med” airflow rate) is continued for another 20 minutes.
After that, these operations are repeated.

Memory Function / Sensors / Auto Detection
Memory Function (Only with the remote controller)
When you stop the operation and then restart, the purifier will resume the operation status before shutdown.
If you operate the purifier for approx. 5 seconds or longer, the operation status will be stored in memory. (If you stop the
operation within less than 5 seconds, the operation status will not be stored in memory.)
The timer setting is not saved in memory.
The saved memory is cleared and the factory settings are restored by unplugging the power plug.
Odor Sensor
The sensor detects odor in air such as cigarette smoke or odor of pet animals. Even when you
feel the air is clean, the purifier may continue the operation if the odor sensor finds any gas
component not removed by the filter.
Any of the following may also be detected by the odor sensor.
Combustible gas when a combustion appliance is running, alcohol, odor of cosmetics, sprays,
vapors, abrupt temperature changes, etc.
P.E-14
Auto Detection
The air purifier unit detects the degree of air contamination in the room with the odor sensor and then starts
automatic operation.
In the first 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 Purify" indicator will blink. After 3 minutes, the "Air Purify" indicator will go off and the purifier
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 Purify” indicator will continue to blink, meaning the unit is checking the room air condition.
After 3 minutes, the indicator will light solidly if the unit is running air purification operations in the Auto Mode.
If you plug in the power cord under contaminated air condition, the sensor sensitivity may be reduced.
