Frequently asked questions
Trouble Shooting
Investigate the problem once again before requesting repairs.
Question Answer
1. The dust sensor does not
change from the red (green)
lamp.
This is due to dusts built up in the dust sensor.
Vacuum dusts from the air inlet with a crevice nozzle of a cleaner and then manually operate the unit for
a while. The sensor will go back to normal.
2. The sensitivity of the dust
sensor seems to be bad (or
too good).
This is because react time of the dust sensor differs depending on the size of room.
If the unit is installed at the lower position of a room, reaction to smoke of cigarettes or others may be
bad. Re-install the unit at the higher place such as on a shelf. If the sensitivity is still bad, adjust the
sensor with sensitivity settings.
3.
Can I wash the
deodorization catalytic unit?
Is replacement necessary?
The deodorization catalytic unit cannot be washed.
(The unit will be ruined.)
Vacuum dusts with a cleaner without removing from the main unit. Replacement is not necessary.
4. What to do if the ionizer
wires are cut?
If the ionizer wires should be cut, replacement is necessary.
Contact your dealer.
5. Is not a problem to use
while the cleaning sign is
blinking?
While the cleaning sign is blinking, electric dust collection and deodorization functions remarkably
deteriorate as electricity supply to the ionizer wires and streamer discharger stops for safety.
Be sure to inspect inside until the sign turns off.
(Blinking is not a problem from a safety viewpoint.)
Case Check Measure
Does not operate.
Is the power plug unplugged? Securely insert it.
Is the front panel correctly set? Securely set it.
Are the battery of the remote controller dead?
Replace with new battery. (page 5.)
The four airflow rate displays, LL

(High) are flashing at the same time.
Is there any foreign matter in the air outlet? Remove the foreign matter.
For other cases, contact your dealer.
Air does not come out.
Cleaning effect is not obtained.
Is the unit installed at a location where the
flow does not pass or are there obstructions
close to the unit?
Remove the obstruction.
Is there too much dust in the pre-filter or
pleated filter?
Clean or replace. (pages 5, 6, 9)
Is too much odors or smoke being generated?
For this case, contact your dealer.
Television screen is distorted.
Is a television or radio installed within 2m of
this unit or is an indoor antenna being used
close to this unit?
Separate the television, radio and indoor antenna from
this unit by 2m or more.
Is the power cord or antenna of the television
or radio close to this unit?
Separate the power cord and antenna of the television
or radio as much as possible away from this unit.
Is the plasma ionizer securely set? Securely set it.
Is dust adhering to the ionizing line of the
plasma ionizer (resin part)?
Clean the plasma ionizer. (pages 11, 12.)
Has water entered into the spurt hole
moistening the negative ionization assembly?
If the negative ionization assembly is dry, the sound will
go away.
Odor is coming from the air outlet.
Is a large amount of odor being generated
temporarily? (Many people smoking or
grilling meat.)
If operated, the odor will gradually go away.
Have you moved the main unit to another room?
Odor from the original room may smell.
If the pre-filter or plasma ionizer dirty? Clean it. (pages 9, 11, 12, 13.)
The cleaning sign does not turn
off or blinks again even after
cleaning the plasma ionizer.
Is the plasma ionizer set securely? Securely set it.
Are not droplets left in the opposing pole
plates or other places?
Wipe off droplets.
Are not bits of tissue left in the plasma ionizer?
Remove bits of tissue.
Did you rinse and soak the plasma ionizer
well after washing the plasma ionizer with
detergent?
Soak well.
Are not the ionizer wires cut? Contact your dealer.
Crackling, buzzing, and
fizzes sounds are audible
during operation.
The streamer discharger makes a fizzes
sound.
This is not abnormal.
