a. Place electronic cells on sides with ionizer section down

(airflow arrows pointing up) on lower rack of dishwasher.

Use care to avoid damage to the collector plates when placing
the cells in the dishwasher.

NOTE:

For some dishwashers with a center spray arm, it may be

necessary to remove the top basket to fit one or both cells inside.

b. Use detergent in accordance with dishwasher manufactur-

er’s instructions.

c. Allow dishwasher to run through its complete wash cycle.

You may also allow it to run through its complete dry
cycle, although this is not necessary.

The electronic cell will be very hot at the end of the
dishwasher’s cycle. Allow it to cool before handling. Hot
water may accumulate in the tubes supporting the collector
plates. Tip the cells to drain tubes.

d. Dry cells completely before turning on power to air

cleaner. This can be done by replacing cells in cabinet and

turning on system fan continuously for approximately 30 to
60 minutes before restoring power to air cleaner.

e. With some dishwashers it may be necessary to re-run

complete cycle or rinse cycle after cells are removed if
homeowner notices dirt stains or residue inside dishwasher.

2. Manual Washing—The electronic cells may be washed manu-

ally by soaking them in a solution of automatic dishwasher
detergent.

a. Provide suitable container large enough to hold one or both

cells.

b. Select automatic dishwasher detergent that dissolves

readily in hot water. Depending on local water conditions,
some brands may form a precipitation or scum. If a
noticeable scum floats to surface, try another brand. The
brand the homeowner finds gives the best results in his
dishwasher will probably give best results washing the
electronic cells.
