INSTALLATION GUIDELINES

• During the operation of the product, please place the unit at least 2m away from equipments
which involve electric wave such as televisions, radios or wave clocks, in case electrical
interference occurs to such equipments.
• 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.
• Place on a stable surface with sufficient air circulation.
• 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 at least 60cm of space from the wall.
The wall behind the air outlet may become dirty as time passes. When using the unit for extensive
period in the same location, use a vinyl sheet, etc., to prevent the wall from becoming dirty. In addi-
tion, periodically clean the wall, etc.

FILTER GUIDELINES

• Follow the instructions in this manual for correct care and maintenance of the filters.

HOW SHARP AIR PURIFIER WORKS

An air purifier draws in room air from its air intake, lets the air pass through an Active Carbon Filter
(Deodorizing Filter) and a HEPA Filter (dust collection filter) inside of the unit, then discharges the air
from its air outlet. The air purifier unit repeats this process by moving its internal fan.
As air passes through, the HEPA Filter can remove dust particles. The Active Carbon Filter gradually
absorbs odor elements as they repeatedly pass through the filter.
(Odor elements are absorbed by HEPA Filter as well.)
Some odor ingredients absorbed by the filters may become separated and may be discharged through
the air outlet and result in additional odor. Depending on the usage environment, this odor may become
strong in a shorter period than expected.
In this case, purchase the optional replacement filter kit FZ-425SEF.
NOTE
• The air purifier is designed to re-
move air-suspended dust and odor,
but not harmful gases (for example,
carbon monoxide contained in ciga-
rette smoke). If the odor sources
still exist, it cannot completely
remove the odor. (for example,
odors from construction materials
and pet odors).
• It is suggested to open the window
a bit when you are smoking in order
to facilitate ventilation.
