View head of air and determine need for cleaning inlet diffuser by running
at service flow and then note difference when bypass open. If significantly
different, disconnect valve from tank and clean inlet diffuser. If IRB slime or
iron build-up is present, ozone level may not be adequate, check settings,
check ozone production.

Clean / change CD cell. Flush CD cells completely by pushing warm
RO or soft water through CD cells to dissolve build-up inside. This
can be done using a bulb syringe or large 60cc syringe. Flush until the
water coming out is clear, usually takes 2-3 times. CD cell must be dry
completely before it can be reinstalled or cell will not produce ozone.
Verify ozone production prior to changing CD cell to understand need
for cleaning frequency at each application. Initiate regeneration, attach
tubing to CD cell inlet and disconnect brine elbow during draw cycle
and blow on tubing to detect ozone odor. Check that indicator light is
working.
•
