A properly functioning filter provides relief for allergy and asthma suffering family members, customers and employees and will ultimately reduce your cleaning and maintenance costs.
How to maintain Friedrich Electrostatic Air Purifiers:
In order to keep the C-90 air purifier operating at peak efficiency, it is important to wash the electronic cell. When the electrostatic plates need cleaning, the C-90B will sound much like a bug zapper. The electronic cell can either be submerged in a bathtub or other suitable container and rinsed, or it can be washed in an automatic dishwasher. If the air is of very poor quality, the efficiency of the electrostatic cell will degrade rapidly, and may necessitate weekly cleaning.
CLEANING - 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 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-fillter can become extremely dirty. With an excessive amount of contamination buildup on the collector plates and the pre-filter, the electronic air filter's effi ciency 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-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.
