The dust/particle sensor can detect large dust (approx. 2.5µm and above) and small particles (approx. 1.0-2.5µm). The particle lamp lights in response to small particles and the dust lamp lights in response to large dust particles.

3 Odor sensor lamp

Indicates the intensity of odors in 3 colors: green, orange, red.

Lamp color: Green (Clean Air), Orange (Low Odor), Red (High Odor)

Names of Parts and Operations (Details)

1 About the LOCK function lamp

Lamp will be lit when the lock function is active. When lit, operations will be restricted. When buttons are pressed, three short beeps will sound.

Note: If the unit is unplugged when LOCK function is active, LOCK function is turned off. The LOCK function lamp (orange) lights up when the function is active.

2 About the dust/particle sensor lamp

• After operation is started, the lamp will light green for the first minute (approx.) regardless of air impurity level.
• The responsiveness of the dust/particle sensor may be poor when airflow rate is high such as "Turbo". This is not a malfunction because the airflow rate is strong and the dust is sucked into the air inlet before it reaches the dust/particle sensor.
• If the responsiveness of the dust/particle sensor is poor, change the sensitivity setting of the sensor. (Refer to Page 15, 16)

3 About the odor sensor lamp

• If operation is started immediately after the power supply plug is inserted, the lamp will light green for the first minute (approx.).
• If odor intensity levels are unchanging, the sensor may not respond even if there is a strong odor in the air.
• The following types of odors may not be detected: pet odors that do not include ammonia, garlic odors, etc.
• As odor perception varies by person, in some cases an odor may be sensed even when the lamp is green. If the odor bothers you, switch to manual airflow rate, and select a high airflow rate. (Refer to Page 12)

The sensitivity of the odor sensor will be determined by odor levels in the first minute after the power supply plug is inserted. Insert the power supply plug when the air is clean (odor-free).

Accessories

• Operation manual (this manual): 1
• Carbon filter: 1 (Attach to the unit before operation. Refer to Page 11)

Preparation Before Operation

1 Positioning the unit in the room

[Diagram: Shows the air purifier with recommended placement distances: At least 40 inches (100cm) away from ceiling, at least 4 inches (10cm) away from wall, at least 12 inches (30cm) away from wall. Shows airflow direction.]

Pointers for good positioning

• Choose a position from where airflow can reach all areas of the room.
• Place on a stable surface. If the unit is placed on an unstable surface, vibrations from the unit may be amplified.
• If interference from the power circuit inside the unit or cables causes disturbance of TV screen images or the emission of static noise from nearby radios or stereos, move the unit to at least 7ft (2m) away from the device. Keep cordless phones and radio-controlled clocks away from the unit also.

Attention

• To avoid staining of walls, position the unit in accordance with the positioning measurements in the illustration. However, note that since this unit draws in dirty air, certain types of wall may become stained even if the measurements are adhered to. In such cases, be sure to maintain sufficient distance between the unit and the wall.
• When used for a prolonged period in the same location, the base of the unit and the floor and surrounding walls may become stained as air is drawn into air inlets near the base of the unit. Periodic cleaning is recommended.

Note:

• If the unit is unplugged when LOCK function is active, LOCK function is turned off.
• The LOCK function lamp (orange) lights up when the function is active.

Adjusting Indicator Lamp Brightness

Indicator lamp brightness is adjustable.

• Press BRIGHTNESS button.
• Each press of BRIGHTNESS button cycles between the settings: BRIGHT, DIM, OFF.

Note:

• This function is useful if the lamps bother you during sleep hours etc.
• The FAN lamps, MODE lamps, and Filter replacement lamp do not turn off even if the brightness is set to OFF. These lamps will be set to DIM.
• If any of the below buttons are pressed when brightness is set to OFF, brightness will change to DIM and return to OFF after about 10 seconds: FAN, UV, MODE.
• If operation is started when brightness is set to OFF, brightness will change to DIM and return to OFF after about 10 seconds.
• If you unplug the power supply plug while the indicator lamp brightness is set to "DIM" or "OFF", the setting will return to "BRIGHT".

Operating MODEs

Select a MODE specific to your needs. Airflow rate is adjusted automatically when the unit is running in a MODE.

• Press MODE button.
• Each press cycles between the MODE lamps (green) and FAN lamps (green).

[Diagram: Shows the MODE button cycling through AUTO FAN, ECONO, and WAVE modes, with associated FAN settings (Quiet, Low, Standard, Turbo).]

Usage and Function

AUTO FAN

Automatic airflow rate adjustment

FAN setting ("Quiet", "Low", "Standard", "High*") is automatically adjusted according to the degree of air impurity. Purifying capacity increases as airflow rate rises. If operating sounds bother you, the airflow rate range can be changed. (Refer to Page 15, 16)

* The maximum airflow rate during AUTO FAN MODE is "High", which is less powerful than "Turbo".

Degree of air impurity corresponds to the volume of dust and the intensity of odors in the ambient air.

ECONO

Saving energy

In Power saving mode within ECONO MODE, the FAN setting automatically switches between Quiet and Low only, and power consumption and operating sounds are reduced. If the air is clean for about 5 minutes, Monitoring mode activates while active the fan starts and stops periodically. Recommended for use during sleep hours.

[Diagram: Shows ECONO MODE flow: Power saving mode (FAN setting switches between Quiet and Low). If air is clean for about 5 minutes, Monitoring mode activates (fan starts and stops periodically, dust and odors are monitored). If dust or odors are detected, the cycle restarts.]

• As the FAN setting is limited to Quiet and Low, air purifying capacity is reduced.
• As air in the room is not drawn in when the fan has stopped, the dust/particle sensor and odor sensor reduce in sensitivity. To prevent this reduction in sensitivity, turn Monitoring mode OFF. (Refer to Page 15, 16)
• FAN setting is adjusted automatically. Airflow cannot be adjusted manually.
• Monitoring mode will not activate during UV emission.

WAVE

Providing wave airflow

A gentle air current is created by switching every 5 minutes between the FAN setting Standard and Low to provide a more natural rhythm to the airflow.

Advanced Settings

Changing the Setting

[Diagram: Shows steps 2 and 3 for changing settings: Pressing BRIGHTNESS OFF to cycle through Low, Normal, High. Pressing MODE to cycle between ON and OFF. Pressing FAN/MODE to cycle between 4 levels and 3 levels. Includes instructions to unplug and replug the power supply.]

* If the lamps do not change even after the settings were changed, unplug the unit, wait at least 5 seconds, then re-insert the power supply plug and repeat the above procedure from the beginning.

Troubleshooting

About the Indicator Lamps

Check the indicator lamp and take the following actions.

[Diagram: Shows the operating panel with indicator lamps.]

FAQs

Please check first before contacting us.

Q: Is it possible to see if UV emission is being performed while the UV function is ON?

A: For safety, the unit is structured so that UV emission cannot be seen.

Q: The sensitivity of the dust/particle sensor seems to be poor...

A: If the dust/particle sensor lens is dirty, the sensitivity may become poor, so clean it regularly. (Page 17)

In addition, the reaction time of the dust/particle sensor varies depending on the size of the room.

Adjust in accordance with the Dust/Particle Sensor Sensitivity Setting. (Page 15, 16)

If the airflow rate setting is set to a strong setting like "Turbo", the responsiveness of the dust/particle sensor may be poor. This is not a malfunction because the airflow rate is strong and the dust is sucked into the air inlet before it reaches the dust/particle sensor.

[Diagram: Shows the Dust/Particle sensor.]

Q: Can I clean the dust collection filter?

A: Maintenance of filter is not possible, but can be replaced. Do not vacuum or wash with water. (Reduced performance of the dust collection filter may result) Replace if dirt buildup is severe. (Page 18)

Q: The color of the dust collection filter is changing...

A: The dust collection filter may turn black due to the collection of dust, or turn yellow or brown due to the UV rays, but this discoloration does not affect the dust collection performance. If you are concerned, replace it. (Page 18)
