Cleaning the SCG Blades
b. To acid clean the SCG blades: Disconnect the AC power from the Power Center. Disconnect the
®
IntelliChlor Salt Chlorine Generator cell communication cable from the Power Center.
c. Mix 0.95 litres (one (1) quart) of muriatic acid with 3.79 litres (one (1) gallon) of tap water in a plastic
bucket.
Working with muriatic acid can be dangerous.
When cleaning the 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 SCG vertically in a 18.9L ( five
(5) gallon) bucket. Pour the acid solution (as described in step c) into the 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 SCG covering the blades. Try not to spill
the acid on the outside of the SCG. If acid does spill on the outside of the 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 SCG for more than thirty (30) minutes. Excessive acid washing will
damage the blades.
e. Remove the SCG from the bucket and place in an empty 18.9L (five (5) gallon) bucket. Rinse the
inside and outside of the SCG thoroughly with clean tap water and inspect. If deposits are still
visible, repeat the acid cleaning process.
f. Rinse the SCG again with clean tap water and inspect. Once clean, replace the 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 300 ppm for pools
and 150 -200 ppm for spas.) and/or improper water balance.
h. Inspect the inside of the S C G every two (2) months (or more frequent in hard water areas).
If no scale or debris deposits are observed inside the 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 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 1-3 ppm
for pools and 3-5 ppm for spas. The IntelliChlor SCG will not produce chlorine below
11° C, ±1.67° C (52° F ±3° F). 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 SCG to
allow diluted acid solution to be poured into
the SCG to immerse the blades for cleaning.
