Troubleshooting

Frequently asked questions
Question
1. The dust sensor does not
change from the red (green)
lamp.
2. The sensitivity of the dust
sensor seems to be bad (or
too good).
3. Can I wash the
deodorization catalytic unit?
Is replacement necessary?
4. What to do if the ionizer
wires are cut?
5. Is not a problem to use
while the cleaning sign is
blinking?
Trouble Shooting
Investigate the problem once again before requesting repairs.
Case
Does not operate.
The four airflow rate displays, LL
(Quiet), L (Low), M (Standard) and H
(High) are flashing at the same time.
Air does not come out.
Cleaning effect is not obtained.
Television screen is distorted.
Crackling, buzzing, and
fizzes sounds are audible
during operation.
Odor is coming from the air outlet.
The cleaning sign does not turn
off or blinks again even after
cleaning the plasma ionizer.
Photocatalytic Air Purifiers
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.
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.
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.
If the ionizer wires should be cut, replacement is necessary.
Contact your dealer.
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.)
Check
Is the power plug unplugged?
Is the front panel correctly set?
Are the battery of the remote controller dead?
Is there any foreign matter in the air outlet?
Is the unit installed at a location where the
flow does not pass or are there obstructions
close to the unit?
Is there too much dust in the pre-filter or
pleated filter?
Is too much odors or smoke being generated?
Is a television or radio installed within 2m of
this unit or is an indoor antenna being used
close to this unit?
Is the power cord or antenna of the television
or radio close to this unit?
Is the plasma ionizer securely set?
Is dust adhering to the ionizing line of the
plasma ionizer (resin part)?
Has water entered into the spurt hole
moistening the negative ionization assembly?
The streamer discharger makes a fizzes
sound.
Is a large amount of odor being generated
temporarily? (Many people smoking or
grilling meat.)
Have you moved the main unit to another room?
If the pre-filter or plasma ionizer dirty?
Is the plasma ionizer set securely?
Are not droplets left in the opposing pole
plates or other places?
Are not bits of tissue left in the plasma ionizer?
Did you rinse and soak the plasma ionizer
well after washing the plasma ionizer with
detergent?
Are not the ionizer wires cut?
Answer
Measure
