This is a unique air cleaning technol-
ogy of the SHARP CORPORATION
for breaking down and eliminating
such potential allergens as the fecal
matter or corpses of aerial mites*1,
viruses *2 and mold and bacteria *3
suspended in the air, and has been
substantiated by third-party organiza-
tions both in Japan and overseas.
When there is a high density of Plas-
macluster ions in the air, the smell of
cigarette smoke trapped in curtains
or sofas is eliminated in about 80
minutes, and when clothing is hung in
a place exposed to the direct air ex-
pelled from the unit generating Plas-
macluster ions, the smell of sweat is
reduced to a virtually imperceptible
level in one night (about 6 hours).

IMPORTANT SAFETY INSTRUCTIONS
When using electrical appliances, basic safety precautions should be followed, including the
following:
- To reduce the risk of electrical shock, fire or injury to persons:
WARNING
• Read all instructions before using the unit.
• Use only a 220-240 volt outlet.
• Do not use the unit if the power cord or plug is damaged or the connection to the wall outlet
is loosened.
• Periodically remove dust from the power plug.
• Do not insert fingers or foreign objects into the intake or air outlet.
• When removing the power plug, always hold the plug and never pull the cord.
Electrical shock and/or fire from short circuit may occur as a result.
• Do not remove the plug when your hands are wet.
• Do not use this unit near gas appliances or fireplaces.
• Remove the power plug from the wall outlet before cleaning the unit and when not using the
unit.
Electrical shock from bad insulation and/or fire from short circuit may occur as a result.
• If the power cord is damaged, it must be replaced by the manufacturer, its service agent,
Sharp authorized Service Centre or similarly qualified person in order to avoid a hazard.
• Do not operate when using aerosol insecticides or in rooms where there is oily residue, incense,
sparks from lit cigarettes, chemical fumes in the air or in very high humidity condition, such as a
bathroom.
• Be cautions when cleaning the unit. Strong corrosive cleansers may damage the exterior.
• Only Sharp Authorized Service Centre should service this air purifier. Contact the nearest Service
Centre for any problems, adjustments, or repairs.
• This appliance is not intended for use by persons (including children) with reduced physical, sen-
sory or mental capabilities, or lack of experience and knowledge, unless they have been given su-
pervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure they do not play with the appliance.

IMPORTANT SAFETY INSTRUCTIONS
CAUTIONS CONCERNING OPERATION
• Do not block the intake and/or air outlet.
• Do not use the unit near or on hot objects, such as stoves or heaters or where it may come into
contact with steam.
• Do not lay the unit down when using.
• Always hold the handle on the back of the unit when moving it.
Holding the front panel when carrying may cause it to detach, thus dropping the unit and resulting
in bodily injury.
• Do not operate the unit without the filter.
• Do not wash and reuse HEPA filter .
It not only does not improve filter performance, it may cause electric shock or malfunction.
• Clean the exterior with a soft cloth only.
The unit surface may be damaged or cracked.
In addition, the sensors may malfunction as a result.
INSTALLATION GUIDELINES
• During the operation of the product, please place the unit at least 2 m away from equipment
which are subject to electrical waves such as televisions, radios or wave clocks.
• Avoid a location where the sensor is exposed to direct wind.
The unit may not operate properly.
• Avoid locations where curtains, etc., come into contact with the intake or air outlet.
Curtains, etc., may become dirty or a malfunction may occur.
• Avoid locations where the unit is exposed to condensation, due to drastic temperature
changes.
(Use under appropriate conditions between 0 and 35˚C in the room.)
• Place on a stable surface with sufficient air circulation.
When placing the unit on a heavily carpeted area, it may cause the unit to vibrate slightly.
• Do not install when there is generation of lampblack, such as in a kitchen, etc.
The unit surface may crack or the sensor may malfunction as a result.
• Leave about 60cm of space from the wall.
The wall behind the air outlet may become dirty as time passes. When using the unit for extended
period of time in the same location, use a vinyl sheet, etc., to prevent the wall from becoming dirty.
In addition, periodically clean the wall.
FILTER GUIDELINES
• Follow the instructions in this manual for correct care and maintenance of the filters.

CARE AND MAINTENANCE
FILTER REPLACEMENT GUIDELINES
Depending on the usage environment, air outlet odour may become
strong after several months.
If dust or odour cannot be removed easily, replace the filters.
(Refer to “Please read before operating your new Air Purifier”)
Guide for filter replacement timing
• The following filter life and replacement period is based on the condition of smoking 10
cigarettes per day and the dust collection/deodorization power is reduced by half com-
pared with that of new filters.
We recommend to replace the filters more frequently if the product is used in a condition
significantly severer than normal household use.

TROUBLESHOOTING
Before calling for repair, please review the list below, since the problem may not be a unit malfunction.
SYMPTOM
REMEDY (not a malfunction)
• Clean or replace the filters if they appear to be heavily soiled.
(Refer to E-11,E-12)
Odours and smoke are not
removed.
• The air could be impure at the time the unit was plugged in. (Refer
to E-5) Pull out the plug from the electrical outlet, and insert the
plug one minute later.
The CLEAN-SIGN Light lights
green even when the air is im-
pure.
• The sensitivity of the sensor become unstable when the open-
ing of the odour sensor is dirty or is clogged.
Clean the dust around the sensor opening using a vacuum
cleaner. (Refer to E-10)
The CLEAN-SIGN Light lights
orange or red even when the
air is clean.
• Clicking or ticking sounds may be audible when the unit is gen-
erating ions.
A clicking or ticking sound is
heard from the unit.
• Check to see if the filters are heavily soiled.
Replace the filters.
• Plasmacluster Air Purifiers emit small traces of ozone which
may produce an odour. These ozone emissions are well below
safety levels.
The discharged air has an aro-
ma or odour.
• Is the unit installed in a location that is difficult for the sensor to
detect cigarette smoke?
• Is the odour sensor opening blocked or clogged?
(In this case, clean the opening.) (Refer to E-10)
The unit does not operate when
cigarette smoke is in the air.
• Check to see if the Lights OFF Mode is selected. If so, then
press the Plasmacluster ON/OFF Button for 3 seconds to acti-
vate the indicator lights.
The Plasmacluster Indicator
Light or the CLEAN-SIGN Light
will not activate.
