Do not splash detergent solution in eyes, and avoid prolonged
contact with skin. Keep detergent and solution out of reach of
children.
c. Before placing cells in washing container, pour in deter-
gent. Use approximately 3/4 cup per cell if container is
about size of cell. Add enough very hot water to cover
cell(s).
d. After detergent has completely dissolved, place electronic
cell(s) in container.
e. Soak cells for 15 to 20 minutes, slosh several times, and
remove.
f. Rinse cells with fine water spray.
g. Fill wash container with clean, hot water and soak cell(s)
for 5 to 15 minutes.
h. Remove cell(s) and let water drain. If water draining from
them feels slippery, detergent still remains. Repeat rinsing
until water from them no longer feels slippery. Inspect for
cleanliness.
i. When both cells have been washed and thoroughly rinsed,
check cells from broken wires and bent collector plates. If
none are found, replace electronic cells and pre-filter in
cabinet. Observe proper airflow arrows on cabinet and cells.
j. Dry cells completely before turning on power to air cleaner.
This can be done by turning on system fan continuously for
approximately 30 minutes before turning on power to air
cleaner.
