How electronic air cleaners work
Electronic air cleaners are an extremely efficient, cost effective method of removing indoor air contaminants. Unlike
standard media that merely block relatively large particles, electronic air cleaners attract and hold particles so small
that an electron microscope is needed to see them.
The PRE-FILTER catches lint, hair and large dust
particles, as room air is drawn in through the rear
grille by the powerful 3-SPEED FAN.
In the IONIZING SECTION of the ELECTRONIC
CELL, billions of microscopic particles, too small
to be caught by the pre-filter, become electronically
charged as they pass through a powerful electric
field.
COLLECTOR PLATES immediately attract and
hold these "charged" particles much like metal filings
are attracted to a powerful magnet. The
accumulated particles are permanently removed
from the air and cling to the metal plates until
washed off.
Finally, an ACTIVATED CARBON FILTER removes
most household odors and fumes as the clean air
is circulated back into the room.

IMPORTANT PRECAUTIONS
Turn off air cleaner before opening top cover to remove
electronic cell and pre-filter for cleaning. Always be careful
when handling the electronic cell. Sharp edges and wires
are capable of inflicting wounds. Care should also be taken
when cleaning because of extremely hot water and
potentially harmful effects of detergents on your skin.
The collector plates of the electronic cell and the pre-filter
can become extremely dirty. With an excessive amount of
contamination buildup on the collector plates and the pre-
filter, the electronic air filter's efficiency decreases. Also, as
dirt builds up on the ionizing wires, the charge process
becomes less efficient.
To prevent this loss of efficiency, the electronic cell and pre-
filter must be cleaned regularly. How often will depend on
actual usage. Cleaning will be more frequent if the air cleaner
is operated continuously or under severe conditions.
CLEANING THE PRE-FILTER
Remove the pre-filter and shake out or brush off the
accumulated dust and lint. If this is not adequate, a vacuum
may be used or the pre-filter can be cleaned with an all
purpose alkaline detergent based cleaner to remove tobacco
smoke and cooking grease stains. A thorough rinsing is
required after each cleaning.
After cleaning, allow to dry and reinsert.
CLEANING THE CARBON FILTER
Occasionally, the carbon filter will need cleaning. Use a
stream of air or a vacuum to remove the dirt. THE
CHEMICAL AND ODOR ABSORPTION CAPABILITIES
CAN NOT BE RESTORED. When the carbon filter can no
longer remove odors from the air, it must be replaced
(Friedrich part number 616-420-00). THE CARBON FILTER
MUST BE IN PLACE FOR THE AIR CLEANER TO
OPERATE.
