HOW ELECTRONIC AIR CLEANERS WORK
Electronic air cleaners are an extremely effi cient, 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 other large
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-fi lter, become electronically
charged as they pass through a powerful electric
fi eld.
COLLECTOR PLATES immediately attract and
hold these "charged" particles much like metal
fi lings 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.

CLEANING
IMPORTANT PRECAUTIONS
Turn off air cleaner before opening top cover to remove
electronic cell and pre-fi lter for cleaning. Always be careful
when handling the electronic cell. Sharp edges and wires
are capable of infl icting 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-fi lter
can become extremely dirty. With an excessive amount of
contamination buildup on the collector plates and the pre-fi lter,
the electronic air fi lter's effi ciency decreases. Also, as dirt
builds up on the ionizing wires, the charge process becomes
less effi cient.
To prevent this loss of effi ciency, the electronic cell and pre-
fi lter 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-fi lter can be cleaned with a mixture
of water and 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 completely and reinsert.
CLEANING THE CARBON FILTER
Occasionally, the carbon fi lter 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 fi lter can no longer remove
odors from the air, it must be replaced (Friedrich part number
616-420-01). THE CARBON FILTER MUST BE IN PLACE
FOR THE AIR CLEANER TO OPERATE.
