A sound is heard.
• Are UNIT1 and UNIT2 correctly set?
Insert UNIT1 until it clicks.
Insert UNIT2 completely to the end.
• Is dust adhered to UNIT1 and UNIT2?
• UNIT2 makes a hissing sound caused by the streamer discharge
during operation.
Depending on the usage conditions, the sound becomes lower or the
sound quality may change, but this does not indicate any problem
with operation.
If the sound persists, change the installation site of the unit.
The lamp lights up or blinks.
• Is there any obstacle in the air outlet?
Disconnect the power plug and remove the obstacle. Reconnect
the power plug and turn the power on.
If the present condition does not change or you can not remove
the obstacle, consult your dealer.
• Are UNIT1 and UNIT2 set correctly?
Insert UNIT1 until it clicks.
Insert UNIT2 completely to the end.
• Are water drops, detergent, or bits of fibre left in UNIT1 and
UNIT2 after cleaning?
After cleaning, wash UNIT1 and UNIT2 well so as not to leave
detergent or bits of fibre, and completely dry them.
• Are the ionised wires cut?
Check the ionised wires. Consult your dealer for replacement with
new ones.
• Did you press the filter reset button for 5 seconds?
Even if the pleated filter is replaced, unless you press the filter
reset button for 5 seconds, the filter lamp does not go off.
Other
• This is a mark made by the streamer discharge and is not abnormal.
• Is a TV or radio installed within 2m of the unit or is an indoor
antenna used close to the unit?
• Is the power supply cord or the antenna of the TV or radio close
to the unit?
Move the unit as far away from TVs, radios and antennas as
possible.
