Cleaning the IECG Blades
b. To acid clean the IECG blades: Disconnect the AC power from the Power Center. Disconnect the
IntelliChlor Electronic Chlorine Generator 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 IECG 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 cell (the cap, o-ring
and washer are provided with the cleaning kit). Place the ICEG vertically in a five (5) gallon
bucket. Pour the acid solution (as described in step c) into the IECG 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 IECG covering the blades. Try not to spill the acid on the
outside of the IECG. If acid does spill on the outside of the IECG, 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
IECG for more than thirty (30) minutes. Excessive acid washing will damage the blades.
e. Remove the IECG from the bucket and place in an empty five (5) gallon bucket. Rinse the inside and
outside of the IECG thoroughly with clean tap water and inspect. If deposits are still visible, repeat
the acid cleaning process.
f. Rinse the IECG again with clean tap water and inspect. Once clean, replace the IECG 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 IECG every two (2) months (or more frequent in hard water
areas). If no scale or debris deposits are observed inside the IECG 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 IECG communication cable plug in the Power Center, then reconnect AC power to the
IntelliChlor 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 Electronic Chlorine Generator 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 acid cleaning kit
(P/N 520670) provides a cap for the IECG to
allow diluted acid solution to be poured into
the IECG to immerse the blades for cleaning.
