REMEDY (not a malfunction)
• Have the batteries been depleted?
• Are the batteries inserted correctly?
• Is a fluorescent lighting in the room flickering due to service
life?
• Clean or Replace the filters if they appear to be heavily soiled.
(Refer to E-12,E-13)
• The air could be impure at the time the unit was plugged in.
(Refer to E-9)
• The sensitivity of the sensors become unstable when the
opening of the odor sensor or dust sensor is dirty or is clogged.
Clean the dust around the sensor opening using a vacuum
cleaner. (Refer to E-11)
• When in Clean Mode ( or Ion Control Mode), the Plasmacluster
Indicator Light color will not change.
• Clicking sound is emitted when the unit is in the Ion Control
Mode, and ticking sound is emitted when the unit is generating
ions.
If the sound is irritating, set the unit away from you.
• Check to see if the filters are heavily soiled.
Replace the filters.
• Plasmacluster Air Purifiers emit small traces of ozone which
may produce an odor. The amount of ozone emitted by the ion
generator is very little which is below the safety levels set by
the IEC 60335-2-65, and it is harmless to the human body.
• Is the unit installed in a location that is difficult for the sensor to
detect cigarette smoke?
• Are the dust or odor sensor openings blocked or clogged?
(In this case, clean the openings.) (Refer to E-11)
• After replacing filters, connect the power cord to an outlet and
press the Filter Reset Button on the remote control. (Refer to
E-12)
• Check to see if the Lights OFF Mode on the Remote Control is
selected. If so, then press the Lights ON/OFF Button on the
Remote Control to activate the indicator light.
(Refer to E-10)
REMEDY
Fan motor disconnected or abnormal.
Operation stops.
• Pressing the POWER ON/OFF button will reset the error
display, but if error occurs again, contact the shop where you
purchased the unit.
