“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 filters 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. To acid clean the cell, mix one quart of muriatic acid with one gallon of tap water in a plastic
bucket.
Always add acid to the water, never add water to the acid. Always wear eye protection
and use rubber gloves. Always work in a well ventilated area.
c. Immerse the cell in the solution. 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 “d”
).
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).
d. Rinse the cell thoroughly with clean tap water and inspect. If deposits are still visible, immerse
the cell again in the solution for further cleaning. Additional acid may need to be added to the
solution.
e. Rinse the cell again with clean tap water and inspect. If clean, replace the cell and resume normal
operation.
f. 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.
g. 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 filtering 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 by turning counterclockwise.
2. Brush with a mildly abrasive green fiber household cleaning pad. Contacts should be clean and bright.
3. Thoroughly rinse the Flow/Temp/Salinity Sensor with clean tap water. Replace and resume normal
operation.
4.
Turn power off and back on in order to recalibrate and reset Flow/Temp/Salinity Sensor. Reset
anytime Flow/Temp/Salinity Sensor is unplugged
