ECONOMICAL CLEAN AIR

The Friedrich electronic air cleaner costs no more to operate than a standard household light bulb. The benefit ts from clean air far outweigh the low operating costs of continuous cleaning. Remember, the more you operate your electronic air cleaner, the cleaner your air will be.

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.

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 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

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.
