“Scale” is a white crusty deposit that forms in excessively hard water or from pool water that is out
of balance and in a scaling condition. Following the installation of the AquaPure, check the cell once
a month for several months. If the cell is clean, replace and re-check at the end of each swimming
season. If the cell shows excessive scaling, go on to Step 2, Acid Wash Cleaning.
2.
Acid Wash Cleaning.
If the electrolytic cell has a tendency to scale, it is recommended that every two
months the cell be removed and inspected for scale formation and/or debris. Some
fi
lters allow debris
to pass through to the cell which could lodge between the plates in the cell. A small amount of scale
formation is normal. If by looking through the cell it is observed that there is excessive scale formation
between the plates or debris is present, the cell must be cleaned as follows:
a
.
Use a high pressure jet of water from a garden hose. If the cell cannot be reasonably cleaned in
this manner, acid cleaning is necessary.
b. Remove the cell from the plumbing. Replace the cell with the spool piece, if necessary. Remove
the sensor from the port.
c. To acid clean the cell, plug the two adjacent ports. Mix one pint of muriatic acid with two quarts
of tap water in a plastic bucket.
Use the appropriate port plugs on the ports. Do not use the
sensor as damage can result.
d. Pour the acid/water mixture inside the cell. A foaming action will begin, which is caused by
scale (calcium carbonate) being dissolved from the plates. If rigorous foaming action does not
begin, the cell does not need to be cleaned (
STOP THE CLEANING PROCESS- go on to next
step “e”
). Otherwise, allow the cell to remain in the solution until the foaming has stopped.
However, do not leave in acid for more than 1/2 hour. *(Excessive Acid Washing will damage
Electrolytic Cell).
e. Rinse the cell thoroughly with clean tap water and inspect. If deposits are still visible, repeat the
cleaning procedure. Additional acid may need to be added to the solution.
f. Rinse the cell again with clean tap water and inspect. If clean, replace the cell and resume normal
operation.
g. If the acid wash procedure is necessary, it is recommended that a sample of pool water be
analyzed by an authorized AquaPure service representative for excessive hardness and/or
improper water balance.
h. If no scale or debris deposits are observed in the cell after two bimonthly inspections, it is not
necessary to continue bimonthly inspections. However, due to possible changes in pool water
chemistry and
fi
ltering effectiveness, it is recommended that the cell be removed for inspection at
least twice a year.
6.5 Flow/Temp/Salinity Sensor Cleaning
One time per year or as needed.
It is rare but scale formations on the
Flow/Temp/Salinity Sensor sometimes
occur and will affect the accuracy of the salinity test.
1. Remove Flow/Temp/Salinity Sensor from the threaded PVC Tee or 3-Port Cell by turning
counterclockwise or removing the union nut.
2. Brush with a mildly abrasive green
fi
ber household cleaning pad. Contacts should be clean and bright.
WARNING
Inhalation of muriatic acid vapor or contact with skin or eyes can cause serious injury or death. Wear goggles and
rubber gloves, and perform cleaning in a well-ventilated area. Add acid to the water, do not add water to the acid
as splashing could result.
