Polaris AutoClear SC Salt Chlorinator
® TM
• Super Chlorination burns out the organic
material that has combined with chlorine
which frees the chlorine for sanitizing. This is
accomplished by raising the chlorine level quickly
and dramatically. To super chlorinate the pool
using the chlorine generating device, set the
chlorine production to 100% and then set the
pump and the cell to run for 24 hours.
• Shocking (Superoxidation) is also a means
of burning out the organic material that has
combined with chlorine. This method involves
the manual addition of chemicals to quickly raise
the level of chlorine. When the chlorine level is
quickly raised to 5 - 15 ppm the pool water is said
to have been shocked.
NOTE: On initial startup of a pool, it is best to shock from an
alternate source, i.e., use a shock treatment available at
your local pool supplier.
Never use dry acid to adjust pH in arid geographic
areas with excessive evaporation and minimal dilution
of pool water with fresh water. A buildup of by-
products can damage the electrolytic cell.
• The pH condition resulting from the operation
of a salt water chlorination system is close to
neutral. However, other factors usually cause the
pH of the pool water to rise. Therefore, the pH in
a pool chlorinated by a salt water system tends to
stabilize at approximately 7.6. If the pool pH rises
above 7.6 have a pool professional test to see if
other factors such as high calcium hardness or
total alkalinity are the cause and then balance
accordingly.
• Total Dissolved Solids (TDS) Adding salt
to pool water will raise the TDS level. While
this does not adversely affect the pool water
chemistry or clarity, the pool water professional
testing for TDS must be made aware salt has
been added for the sanitizing system. The
individual performing the TDS test will then
subtract the salinity level to arrive at the correct
TDS level.
• New pool water in a recently filled or newly
refinished pool may contain undesirable
matter which could interfere with the salt water
chlorinator's ability to sanitize properly. Make
sure the water is tested by a pool professional
and properly balanced before turning on the
chlorinator system. New plaster pools have a
constant acid demand for six (6) months. Test
often and maintain a proper pH to avoid excess
scaling of the cell.
• Sequestering Agents can be used to
compensate for source water which may have
unusually high calcium hardness. High calcium
hardness can contribute to scale formation in
the pool. Sequestering agents will help keep
minerals in solution and under some conditions
can prevent scaling from happening. Consult
your pool professional about the use of a
sequestering agent.

4.4 Optimum Pool Water Conditions

• In accordance with Association of Pool and Hot
Tub Alliance (PHTA) standards, we recommend
the following water balance conditions be
maintained on an ongoing basis to protect the
pool finish and the equipment and to ensure the
pleasing appearance of the water. The chlorine
generating device is warranted to operate
properly only if the following conditions are met:
Free Chlorine When using Nature2 pool
sanitizers, check the Nature2
manual for reduced minimum
free chlorine levels. 1 - 3 ppm.
Continuous exposure to levels
above 3.0 ppm may cause
corrosion of pool metals.
Combined None
Chlorine (Super chlorinate to remove all
(Chloramines) chloramines.)
pH 7.4 - 7.6
(Use muriatic acid to lower pH and
soda ash to raise pH.)
Chlorine 10 - 50 ppm
Stabilizer (For outdoor pools only.)
(Cyanuric
Acid)
Total
80 - 120 ppm
Alkalinity
Calcium
175 - 400 ppm
Hardness
Metals (Iron,
None
Manganese)
Nitrates None
Phosphates
None

4.5 Chlorine Testing

Use a home test kit or ask your pool professional to
test your water. It is recommended that chlorine test
samples be taken from two (2) places, described below.
Compare the two (2) samples. A higher level should be
found at the pool return line. The higher level at the pool
return line indicates the salt water chlorinator system is
producing chlorine.
1. At the pool return line.
2. 18 in. (46 cm) below the surface and well away
from the pool return line.
