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
cleaning agent 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. (See Carbon Filter Reorder Form packed with this unit or contact your
nearest Friedrich dealer.) Under normal operating conditions the carbon filter should be
replaced every 3-6 months. THE CARBON FILTER MUST BE IN PLACE FOR THE AIR
CLEANER TO OPERATE.
CLEANING THE ELECTRONIC CELL
The simplest method of cleaning the electronic cell is to use an automatic dishwasher.
The dishwasher provides the correct cycle of wash, rinse and dry. Water temperatures
normally found in dishwashers will not harm the cell.
1. After turning off the air cleaner, remove the cell and gently place on the dishwasher
rack with airflow arrows pointing up. In some dishwashers, it may be necessary to
remove the top rack. BE EXTREMELY CAREFUL WHEN PLACING ON
DISHWASHER RACK TO NOT DAMAGE IONIZER WIRES OR BEND
COLLECTOR PLATES.
2. Use any available household dishwasher detergent recommended for use in your
appliance and follow manufacturer’s instructions.
3. Not all dishwashers may be capable of holding the electronic cell. Be sure to
compare the internal size of the dishwasher to the dimensions of the electronic
cell (16" high x 12 1/2" wide x 4 1/2" deep.) All parts of the dishwasher must be
able to move freely.
4. Take care to avoid damaging the cell when removing it from the dishwasher.
GENTLY LIFT THE CELL STRAIGHT UP TO PREVENT DAMAGE TO IONIZER
WIRES AND COLLECTOR PLATES.
5. The cell may be hot when removing it from the dishwasher. Allow to cool or wear
protective gloves. Make sure that all water is drained off when removing the cell
from the dishwasher.
6. If dirt stains or detergent residue remain after washing, it may be necessary to
rewash the cell or switch detergent.
7. The electronic cell must be COMPLETELY dry before replacing it in the air cleaner
for use.
