ALTERNATE CELL CLEANING METHOD
If an automatic dishwasher is not available or not of suffi cient size to accommodate the cell,
a large container capable of holding the electronic cell can be used.
1. Mix an automatic dishwasher detergent with hot water in a ratio of 4 oz. of detergent
to one gallon of water. Water temperature should be between 150° F and 170° F. Be
careful to avoid prolonging skin contact with solution and DO NOT splash solution in
the eyes.
2. Soak the cell in the solution for about 15 minutes. The solution should be agitated in
some way every 2 to 3 minutes by sloshing or stirring the solution.
3. Remove the cell from the cleaning solution and place in a clean container of hot water
(150° F to 170° F) for rinsing and let set for 10 minutes.
4. Remove the cell from the rinse water and allow to drain and dry before using.
5. If there is any detergent residue remaining, rinse again, since it may affect the effi ciency
of the air cleaner.
NOTE: The ionizer wires may become so dirty that an occasional cleaning is
recommended. With a damp cotton ball, wipe the ionizer wires by placing the wire
between fi nger and thumb.
Occasionally, after the cleaning process, the cell may seem stained. If the stain is black
or very dark, it is probably detergent residue and should be rinsed off at once. If yellowing
appears, it is probably stain from tobacco or other smoke. The yellowing does not affect air
cleaner effi ciency. Use an ammonia-based detergent to clean tobacco tar and other smoke
residue from the collector plates.
After the cell has been washed, check for broken ionizer wires and bent collector plates. If
broken wires are observed, return unit to Authorized Warranty Station for wire replacement. If
bent collector plates are observed, carefully straighten with a screwdriver or other fl at object.
BE CERTAIN THAT NO TWO COLLECTOR PLATES ARE TOUCHING AS THIS WILL
CAUSE AN ARC AND PREVENT THE AIR CLEANER FROM OPERATING PROPERLY.
The operation light will not light and the electronic cell will not function.
Remember that the electronic air cleaner has a cell key which prevents the cell from being
positioned incorrectly. If the cell seems stuck when being inserted or the access cover will not
fi t securely, check to be sure that the cell is being positioned properly. If excessive force is used,
the cell or air cleaner unit could be damaged. Airfl ow arrows point toward fan motor.
If the cell is placed into the air cleaner while still damp, the indicator light may not come
on until the cell is dry, which would normally take about two hours. If the cell is energized
and annoying snapping sounds occur, the cell should be removed from the air cleaner and
allowed to thoroughly dry.
