•
Provide a large enough container, such as a laundry tub
or plastic tank, to hold at least one cell.
•
Mix alkaline base detergent, such as commercial or home
electric dishwashing detergent (either liquid or powder)
with hot water. Follow the instructions on the detergent
package. The water temperature should be between
150°F and 190°F (66°C and 88°C). When using a cold
water detergent, follow instructions included with the
detergent.
NOTE: Be sure to avoid prolonged skin contact with the
solution. Do not splash solution in eyes.
•
Soak the cells in the solution for up to 15 minutes; agitate
the cells up and down. See Fig. 12.

•
Remove the cells from the detergent solution; spray with
hot water as a prerinse, if desired and place cells in
another container of clear hot water (150°F to 190°F
[66°C to 88°C]) for final rinsing. Rinse the cells for five to
ten minutes.
•
Remove the cells from the rinse water. Allow the cells to
drain and dry before energizing them. For optimum water
drainage from tubes, stand the cell on one of its corners.
•
Wipe ionizer wires to remove any deposits remaining on
the wires.
•
Check the collection plates of the cells for any detergent
residue. Repeat the rinse process if there is any residue
remaining. Buildup can reduce the F57 efficiency.
About Discolored Aluminum
Occasionally, the cell or prefilter can seem stained after the
soaking process. When the stain is black or very dark, it is
probably dirt residue and the cell should be rewashed. White
detergent residue can also affect the F57 efficiency and
should be rinsed off. When yellowing appears, it is probably
staining from tobacco smoke or other airborne dirt.
Moderate discoloration does not affect the F57 efficiency.

Cleaning the Cells Using Air
Pressure, Water Pressure or Low
Pressure Steam
The following alternative methods can be used to clean some
contaminants from the F57 cells. See Fig. 13. To prevent
damage to the prefilter, do not use pressure or steam
methods on the prefilter.
• High Pressure Air or Water. Care should be taken to avoid
damage to the cells. If detergent is required with the high
pressure water, use an alkaline base detergent. Do not
use an acid detergent.
• Steam. Extreme care must be taken when steam cleaning
to avoid warping or bending the collector plates of the
cells. Remember that the cells are hot after steam
cleaning and care must be taken to avoid burns. Use only
low pressure or wet steam.
NOTE: Do not use steam at pressure greater than 5 psi
(35 kPa) or temperature hotter than 250°F (121°C).

to remove collected cells contamination.
