Disassembly and Cleaning
NOTE: TO ENSURE PROPER OPERATION, FILTERS SHOULD BE CLEANED AT REGULAR INTERVALS.
FAILURE TO CLEAN ELECTRONIC FILTER WILL VOID WARRANTY.
1. Turn off unit and disconnect line cord from outlet.
2. Remove fasteners and variable speed control knob from cover assembly.
3. Lift cover from chassis.
4. Remove ground screw from base of chassis connecting chassis to the electronic cell.
Lift cell from chassis, being careful not to bend any of the plates on the electronic cell.
5. The electronic cell may be cleaned in several ways, but the best way is to soak
it in a container of hot water into which has been dissolved a cup of dishwasher detergent or other
cleaner that is safe for aluminum. After soaking for 10-15 minutes, agitate the filter (cell) in the
solution to release some of the particles. Alkaline cleaners, such as our LA-99 heavy duty cleaning
solution, may be used with care. Be certain to read and follow all directions carefully to avoid
damage to the aluminum cell Components caused by harsh chemical agents.
It may be necessary, if the cell is extremely dirty, to repeat the soaking process or to
take a small soft brush to the plates of the cell. If this is done, care should be taken not to damage
the plates or the fine ion wires between the widely spaced plates on the ionizer section of the cells.
After soaking, rinse off all traces of the detergent with clean warm water and allow the excess to
drain off. Before replacing the cell into the chassis, make sure the cell is completely dry. The
electronic cell may also be washed in the normal cycle of a household dishwasher, but caution
should be taken to avoid damage to the closely spaced plates.
6. DO NOT WASH THE CARBON AFTER-FILTER. This filter should be brushed or cleaned with a
vacuum cleaner if any dust is present. This filter should also be replaced when there is an indication
that it is no longer absorbing odors. Normal replacement is approximately every 3-6 months.
