Cleaning the IntelliChlor
b. To acid clean the IntelliChlor SCG blades: Disconnect the AC power from the Power Center.
Disconnect the IntelliChlor SCG cell communication cable from the Power Center.
c. Mix one (1) quart of muriatic acid with one (1) gallon of tap water in a plastic bucket.
Working with muriatic acid can be dangerous.
When cleaning the IntelliChlor SCG always wear rubber
gloves and eye protection. Always add acid to water, do
not add water to acid. Always work in a well-ventilated
area. Splashing or spilling acid can cause severe personal
injury and/or property damage.
d. Screw the cap with washer and o-ring onto the threaded end of the IntelliChlor SCG cell (the cap, o-
ring and washer are provided with the cleaning kit). Place the Intellichlor SCG vertically in a five
(5) gallon bucket. Pour the acid solution (as described in step c) into the IntelliChlor SCG until the
cell blades and salinity probes are just covered. Allow the acid solution to bubble, and to clean the
blades. Note: The acid should only be contained inside the IntelliChlor SCG covering the blades.
Try not to spill the acid on the outside of the IntelliChlor SCG. If acid does spill on the outside of
the IntelliChlor SCG, wash it off with water. A foaming action will begin, which is caused by scale
(calcium carbonate) being dissolved from the blades. If rigorous foaming action does not begin, the
blades do not need to be cleaned (STOP THE CLEANING PROCESS - go on to step "e).
Otherwise, allow the blades to remain immersed in the solution until the foaming has stopped.
However, do not leave acid in the IntelliChlor SCG for more than thirty (30) minutes.
Excessive acid washing will damage the blades.
e. Remove the IntelliChlor SCG from the bucket and place in an empty five (5) gallon bucket. Rinse
the inside and outside of the IntelliChlor SCG thoroughly with clean tap water and inspect. If
deposits are still visible, repeat the acid cleaning process.
f. Rinse the IntelliChlor SCG again with clean tap water and inspect. Once clean, replace the
IntelliChlor SCG and resume normal operation.
g. If the acid wash procedure is necessary, it is recommended that a sample of pool water be analyzed
by a pool professional for excessive calcium hardness (i.e. ideal range is 200 to 400 ppm) and/or
improper water balance.
h. Inspect the inside of the IntelliChlor SCG every two (2) months (or more frequent in hard
water areas). If no scale or debris deposits are observed inside the IntelliChlor SCG after four (4)
months, it is not necessary to continue inspections every two (2) months. 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.
i. Reconnect the IntelliChlor SCG communication cable plug in the Power Center, then reconnect AC
power to the IntelliChlor SCG Power Center.

Winterizing

Very little chlorine production is needed in cold water so long as free chlorine levels are maintained at 2.0 - 4.0
ppm. The IntelliChlor SCG will not produce chlorine below 52° F ±3° F (11° C, ±1.67° C). This low-
temperature cutoff extends the life of the cell. If preventative measures are not taken, freezing water may cause
severe damage to the cell. Prevent freeze damage to the cell by running the pool pump continuously or winterize
the pool by draining water from pump, filter, and all intake and return lines. Remove the cell, clean and store it.

Note: The IntelliChlor SCG acid cleaning kit
(P/N 520670) provides a cap for the IntelliChlor
SCG to allow diluted acid solution to be poured
into the IntelliChlor SCG to immerse the blades
for cleaning.
