Cleaning (Continued)

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.
