WARNING
Do not use a damaged power cord and plug, or a loose power outlet. This may cause electric shock, short circuit, or fire. Do not damage the power cord and plug. Do not unnecessarily bend, pull, twist, or bind the power cord, place it close to a hot object, place a heavy object on it, trap it between objects, or modify it. •If the power cord is damaged, it must be replaced by
the manufacturer, its service agents, or a similarly qualified person to avoid hazards.
This may cause damage, resulting in fire or electric shock. (Also take care that a pet does not bite the power cord.) Do not repair, disassemble, or modify the unit. This may cause fire or electric shock. For repairs, contact the retail store where you purchased the product. Do not put a wire, pole, other foreign object or a finger into an air inlet, outlet, rotating units or any other opening into the unit. This may cause electric shock or injury.
Use a 220-240 V AC power outlet. Using other than a 220-240 V AC power outlet may cause electric shock, short circuit, or fire. Remove the power plug before cleaning. Also, do not remove the power plug with a wet hand. This may cause electric shock or injury. Remove dust from the power plug regularly. If dust accumulates, humidity, etc. may cause an insulation failure, resulting in fire. If the unit is operating abnormally or fails, stop using it immediately. • The unit does not operate when the power switch
is turned ON.
• The unit, power cord, or plug is abnormally hot. • There is an abnormal noise or vibration during
operation.
• There is a burning smell. • The operating sound is abnormally loud. • Mounting screws are corroded or loose. • The earth leakage circuit breaker trips frequently. • There is another abnormality or failure. Failure to do so may cause fire, electric shock, or injury. Immediately turn OFF the power switch and disconnect the power plug, and then contact the retail store.
Do not allow flammable gas to be sucked inside or use the unit where flammable gas accumulates. (Factory, beauty salon, etc.) This may cause fire. Do not use the unit in a location with the oily smoke of machine oil or other oil. This may cause cracking, resulting in electric shock. Do not place the unit close to flammable objects or objects lit with fire, such as cigarettes or incense sticks. This may cause a fire. Do not stand on, sit on, or lean on the unit, or place objects on it. Do not pull the louvre with your fingers. Do not place in an unstable location. This may cause the unit to topple or fall and cause injury. Do not wipe the unit with benzene or thinner or spray insecticide or other chemicals onto it. This may cause electric shock, fire, or cracking and cause injury. Do not operate the unit when using an insecticide that produces smoke. An accumulation of chemical components may be released from the air outlet, and be harmful to health. After using an insecticide, ventilate the area sufficiently prior to operating the unit. Do not move the unit except by holding the handles. This may cause the unit to topple and fall, or pinch fingers, causing injury. Do not install the unit where water may be spilt onto it or where there is a lot of humidity such as in a bathroom. This may cause electric shock. Should water or other liquid be spilt onto the unit, stop operation and remove the power plug, and then contact the retail store where you purchased the product.
Insecticide
Do not lay the unit horizontally when removing a filter. This may cause dust to enter inside, resulting in fire or electric shock. Do not use a damaged filter or operate the unit while a filter is removed. This may cause dust to enter inside, resulting in fire or electric shock. Do not come close to the main unit while the unit is rotating. In particular take care regarding children. If you are sandwiched between the wall while rotating, it may cause an injury. Place the unit in a location where it will not bump into a wall or furniture while the unit is rotating. This may cause damage to the wall or furniture. Hold the bottom of the inlet panel when installing the inlet panel. If the top of the inlet panel is held, your hand can be trapped causing injury. When using the unit in combination with a combustion appliance, ventilate the room occasionally. Carbon monoxide cannot be removed from the air, so not ventilating the room may cause carbon monoxide poisoning. When disconnecting the power plug, pull it out straight while holding not the cord but the power plug. Failure to do so may cause electric shock or a short circuit resulting in fire. When the unit will not be used for a long time, disconnect the power plug. Failure to do so may cause the insulation to deteriorate, resulting in fire from a short circuit or an electric shock.

<Automatic rotation operation range>
The automatic rotation automatically turns the main unit according to the person’s location detected by the human sensing. The main unit is stopped at any of 1to 5in the figure on the right.
zThe operation range is approx. 90 degrees. It differs from the detection range of the human sensing.
zThe main unit may not turn to face a person when, for example, the human sensing has detected
multiple persons.
zWhen the human sensing detects a person directly in front of the main unit, the main unit is not
moved and remains facing forward.
zThe automatic rotation will not operate when the main unit hits a wall or other object because at
least 20 cm of space was not provided around it, when the main unit hits an object nearby that prevents turning, or when the main unit is restrained from moving.
<Louvre operation range>
The louvre is stopped at any of 1to 3in the figure on the right. 1 When a person is not detected by the human sensing while Normal operation mode is selected
→Air is blown all over the room including far away locations.
2 When a person is detected by the human sensing while Normal operation mode is selected
→Air flow is controlled so that air is not blown directly at a person.
3 When manual operation is selected
→Air flow is controlled so that sufficient air-flow volume is maintained.
Features Human sensing detection
Operations (when Normal Operation Mode is Selected)
The direction to a person’s location is detected by the human sensing. The air inlet and outlet are moved by the automatic rotation and the optimal air flow is created by the louvre according to the person’s location.
z The human sensing detects a person’s location within a range of approx. 150 degrees while turning left and right.
(The human sensing lamp flashes green while the human sensing is performing the detection operation.)
z The human sensing measures the indoor temperature in the room and determines the direction to a person’s location from variations in
the temperature.
z The human sensing operates only when the main unit is stopped and faces forward.
(The human sensing does not operate when the automatic rotation is operating or the main unit faces a direction other than the forward direction.)
 A person cannot be detected in locations such as the following.
z Outside of the detection area z Where there is an obstacle (furniture or other object) to the main unit
 A person cannot be detected correctly in cases such as the following.
z When there is something that changes the temperature
significantly within a short period of time (e.g., television, air conditioner, refrigerator)
z When the room temperature or the temperature of the floor and
walls is high (rough guide: 30°C or more)
z When the room temperature or the temperature of the floor and
walls is low (rough guide: 8°C or less)
z When skin is not exposed because the person is under a blanket
or wearing a lot of clothes
z When the heat source cannot be detected such as when there is a
small child or pet or a person wearing a lot clothes
z When the distance to the person is short (rough guide: 0.5 m or
less)
z When the distance to the person is long (rough guide: 6 m or
more)
z When the person is not moving much
<When the human sensing cannot detect a person>
z When the human sensing cannot detect a person and none of the above apply, perform the
check described in the following procedure. (Perform the check when the room temperature is 15 to 28°C.) 1
Turn ON the power switch and stand in the position indicated by “A” in the figure on the right.
2 When the human sensing turns right and passes you, move to the position indicated by
“B” in the figure on the right.
→Operation is normal if the main unit is moved to face you (position indicated by “B”) by
the automatic rotation.
<Turning off the human sensing> P.14
When operation is started, the human sensing begins detection. The human sensing turns left and right while the main unit remains facing forward. After completing one left and right movement (takes approx. two minutes), the human sensing determines the direction to a person’s location. <When a person is present>
1 The main unit is turned toward the person’s location automatically and then stopped by the
automatic rotation.
2 The louvre controls the air-flow direction so that air does not blow directly at the person. 3 Contamination is monitored while removing the dust in the area around the person. 4 When contamination in the room is detected by the PM2.5 Sensor and odor sensor, the air
volume is changed automatically.
After approx. 15 minutes, the main unit is turned to face forward and then stopped by the automatic rotation. The human sensing turns left and right again to detect the direction to a person’s location.
z If more than one person is detected, the automatic rotation stop position is
determined automatically depending on the number of persons and the direction to the persons.
<When a person is not present>
1 The louvre controls the air-flow direction so that air is blown over the entire room while the
main unit remains facing forward.
2 Contamination is monitored while removing the dust in the entire room. 3 When contamination in the room is detected by the PM2.5 Sensor and odor sensor, the air
volume is changed automatically.
After approx. three minutes, the human sensing turns left and right again to detect the direction to a person’s location.
About Human Sensing, Automatic Rotation, and Louvre
The human sensing turns approx. 150 degrees in the left and right directions to detect the direction to a person’s location.
The air inlet and outlet are moved by the automatic rotation which moves the main unit according to the person’s location. The optimal air flow is created by the louvre in order to clean the area around the person.
Air flow is controlled so that air is not
blown directly at a person.
Air is blown over the entire room.

1. Blower fan
(motor) does not
rotate (power
does not turn
ON).
• How to determine whether the DC motor has a malfunction
The following table shows the values for a normal motor that was measured with a
multimeter.
Themotorhasamalfunctionifanyvalueisverydi󰀨erentfromthenormalvalue.
Measurement method (pin number of P107 and P108 connectors)
Tester + terminal Tester - terminal Tester measurement mode Normal value Malfunction diagnosis
Pin 1 (red) Pin 4 Resistance Innity
Motor internal circuit breakdown
Pin 6 (white) Pin 4 Resistance 10sofkΩ Motor internal circuit breakdown
Pin 7 (yellow) Pin 4 Resistance 10sofkΩ Motor internal circuit breakdown
Pin 8 (blue) Pin 4 Resistance Innity Motor internal circuit breakdown
Pin 4 (black) Pin 1 Diode 0.5 to 2 V Motor internal circuit breakdown
Any pin Outer casing of motor Resistance Innity Motor insulation breakdown
The above is the diagnostic method for when the motor is isolated.
Regardless of the rotation state, do not test the motor when the connectors are connected.
2. Dust is not
collected (air
volume is low).
3. Deodorizing is
not performed
(deodorizing
performance is
low).
4. The odor monitor
does not work.
5. The PM2.5
monitor or dust
monitor does not
work.
Is an operation mode lamp
lit when you press the
operation switch?
Check the continuity of the current fuse.
The current fuse has blown.
Replace the power supply control circuit board.
* Pull out the power plug before checking.
Check the connection cables and connectors
of the display operation circuit board and
power supply control circuit board.
Check the output voltage at the
connectors P107 and P108 of the power
supply control circuit board within 45
seconds after turning ON the power.
If 280 VDC is not output normally between
the pins 1 and 4, 15 to 19 VDC is not output
normally between the pins 6 and 4, and 1 to
6 VDC is not output normally between pins 7
and 4, replace the power supply control circuit
board. If the voltages are output normally,
replace the blower motor (pin 4 is GND).
