• 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 fi lled or newly refi nished 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.
• 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 Spa Professionals (APSP) standards, we recommend the following water
balance conditions be maintained on an on-going basis to protect the pool fi nish and the equipment and to ensure the
pleasing appearance of the water. The Jandy
conditions are met:
Free Chlorine
Combined Chlorine (Chloramines) None (Super chlorinate to remove all chloramines.)
pH
Chlorine Stabilizer (Cyanuric Acid) 10 - 50 ppm (for outdoor pools only)
Total Alkalinity
Calcium Hardness
Metals (Iron, Manganese)
Nitrates
Phosphates

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.

4.6 Salt (NaCl Sodium Chloride)

4.6.1 When to Add Salt

Add salt to the pool if the salt is too low (see Table 1). For a new pool or newly resurfaced pool it is recommended to
wait at least 30 days (surface should be completely cured) before adding salt. Follow the pool surface manufacturer's
guidelines for your particular pool. For vinyl and fi berglass pools, salt can be added at start up.
® AquaPure ® Ei is warranted to operate properly only if the following
TM
1 - 3 ppm. Continuous exposure to levels above 3.0 ppm may cause
corrosion of pool metals.
7.4 - 7.6 (Use muriatic acid to lower pH and soda ash to raise pH.)
80 - 120 ppm
175 - 400 ppm
None
