1. pH Level Test: Test the pH level of your pool water with a reliable test method. If necessary, adjust

according to your pool professional’s recommendations. APSP’s recommended ideal range for pH is

7.4 to 7.6, although 7.2 to 7.8 is an acceptable range under APSP’s guidelines.

Note: Never use dry acid (sodium bisulfate) to adjust pH in arid geographic areas with

excessive evaporation and minimal dilution of pool water with fresh water. A buildup of

byproducts can damage the IECG.

Total Alkalinity Test:

Test the pool water for total alkalinity with a reliable test method. Adjust

according to your pool professional’s recommendations. APSP’s recommended ideal range for total

alkalinity is 80 to 120 ppm.

Chlorine Test: Test the pool water the free chlorine level with a reliable test method. Maintain ideal

range by adjusting the IntelliChlor Electronic Chlorine Generator Sanitize Output settings. See “More

and Less Output Buttons,” on page 8.

• Defined Free Chlorine is 2.0-4.0 ppm, per APSP recommendations.

Note: Above 4.0 ppm of chlorine may cause excessive corrosion of metal components and

possibly cause damage to associated pool equipment.

Note: It is recommended that free chlorine readings be taken from samples of pool water taken

from two (2) places, one at the pool return line, the other well away from the pool return line.

Compare the test results. A higher free chlorine level should be found at the pool return line.

The higher free chlorine level at the pool return line indicates IntelliChlor Electronic Chlorine

Generator is producing chlorine.

Monthly Service

To ensure that the correct chemical balance is maintained in your pool, it is important to perform the following

recommended salt and pool water tests every month using a reliable test method.

Salt Level Test: Check salt display lights on the unit and check that the green “GOOD” light is on

and is not flashing.

• If the yellow “CHECK SALT” LED light is on (see page 5), test the pool water salinity using a

reliable test method. Add salt if necessary to bring the salt level to 3000 - 3500 ppm by following

the procedures and charts described on page 13 and 14.

• If salt level does not rise after 24 hours, see “Troubleshooting,” page 33.

• If the red LOW LED salt light is on, no chlorine is being produced. Add salt to the pool water

(see charts beginning on page 13).

Pool Water Sample: Take a sample of the pool water to your local pool store for testing.
