1 Introduction System Description The IntelliChlor™ salt chlorinator uses a process known as electrolysis to produce Sodium Hypochlorite (liquid chlorine) from a low concentration of salt added to the pool water. Hypochlorite kills bacteria, oxidizes organic material, and kills algae, then reverts back to salt. IntelliChlor then reuses the salt and the process starts over again. The IntelliChlor system is comprised of the Power Center and Electrolytic Cell.
2 Electrolytic Cell Controller The electrolytic cell controller includes a control panel with buttons and LED indicators to fully control and produce chlorine. The cell controller measures the water temperature and salt level to optimally produce chlorine. If the salt level is too low (red on salt display), the cell is turned off until salt is added to the pool. The controller has a self-cleaning cycle which reverses the cell polarity, reducing calcium buildup.
3 Power Center The Power Center converts AC electrical current to a low voltage DC current which is required by the cell to perform the electrolysis. The power supply is connected with the pool circulation pump electrical source so that the electrolytic cell only operates when the pool pump is on. The enclosure can be mounted vertically on the wall up to 15 feet away from the cell controller.
4 Loop Plumbing Diagram The IntelliChlor will operate in water flow rates from 15 gallons per minute up to 110 gallons per minute (the limit of 2” plumbing). For flow rates over 80 gallons per minute, it is recommend that you use a bypass loop (shown below) for best chlorine production. Installations with flow rates over 80 gallons per minute are those that have in-floor cleaning systems or boost pumps. These systems should use a bypass loop with the IntelliChlor.
5 Section 1 IntelliChlor Control Panel This section describes the IntelliChlor control panel status LEDs and the More, Less and Boost/On/Off control buttons. Salt Level Status LEDs The salt level is checked daily and is displayed on this section of the unit. • • • Green: Good salt. The water salt level is above 2900 ppm, the cell will produce chlorine. Flash green: Salt is above 4000 ppm. Chlorine is being produced but the pool water may be corrosive to other pool equipment.
6 Operator Control Panel (continued) Sanitizer Output LED Indicators The five LED indicators display as a bar graph to show in 20% increments, the amount of time the chlorine is produced per hour. In BOOST mode, these LEDs scroll in a pattern.
7 Section 2 Operating IntelliChlor This section describes the start up procedure and operating instructions for IntelliChlor. Initial Start up Period For the first 30 days of cell operation, the self-cleaning cycle will be set to 2 hours. After 30 days has elapsed, the unit will automatically set itself to four hour self-cleaning cycle. This feature will clean the cell more often on a new pool installation, then go to a more standard self-cleaning cycle for longer cell life.
8 Startup Procedure (Super Chlorination) Shocking (Super Chlorination) is recommended before pool startup. Start out with clean pool water from the beginning. IntelliChlor will build up a sufficient level of chlorine for sanitation in several hours. However, if pool water has a high demand from the start-up IntelliChlor will not be able to produce enough chlorine to reach break-point chlorination. So, it is best to super chlorinate from an outside source at the time of pool startup.
9 Section 3 User Maintenance This section describes how to maintain the IntelliChlor chlorination system. Daily service. None is needed. Weekly service. 1. Chlorine Test: Test pool water chlorine level with a reliable test kit. Maintain ideal range by adjusting IntelliChlor chlorine production rate. See “Buttons,” on page 6. • Chlorine is 1-3 PPM. Note: Above 3.0 PPM of chlorine may cause corrosion of pool metals and possibly cause damage to associated pool equipment.
10 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. 1. Salt Level Test: Check salt display lights on the unit and check that the green “GOOD” light is on. • If the yellow ADD Salt light is on (see page 5), add salt by following the procedures and charts described on page 14 and 15. • If salt level does not rise after 24 hours, see “Troubleshooting,” page 25.
11 Electrolytic Cell Cleaning 1. Automatic Cleaning. This unit has an automatic cell-cleaning feature (Cell Reversing) that removes scale deposits from the electrolytic cell. Note Automatic Cleaning does not interrupt Chlorine Production. “Scale” is a white crusty deposit that forms in excessively hard water or from pool water that is out of balance and in a scaling condition. If the cell shows excessive scaling, you need to perform an acid wash cleaning. Proceed to “Acid Wash Cleaning,” Step 2. 2.
12 Chemistry You Need to Know 1. Chlorine Stabilizer (cyanuric acid) is needed in outdoor pools to maintain proper levels of chlorine. Most unstable chlorine is destroyed by the UV radiation from the sun within 2 hours. Chlorine stabilizer should be maintained between 50 - 75 PPM. See Table 3, page 16. 2. Nitrates can cause extremely high chlorine demands and will deplete chlorine from your swimming pool. In some cases Nitrates may even lower your chlorine levels to zero.
13 Optimum Pool Water Conditions In accordance with the Association of Pool and Spa Professionals (APSP) standards, it is recommended that the following water balance conditions be maintained on an on going basis to protect the pool finish and equipment and ensure the pleasing appearance of the water. IntelliChlor is warranted to operate properly only if these conditions are met. Free Chlorine: 2.0 - 3.0 PPM. Above 3.
14 Chlorine Testing It is recommended that chlorine test samples be taken from two places. Compare the samples. A higher level should be found at the pool return line. The higher level at the pool return line indicates IntelliChlor is producing chlorine. 1. At the pool return line. 2. 18 inches (457 mm) below the surface and well away from the pool return line. What Type of Salt to Use The purer the salt the better the life and performance of the electrolytic cell. Use a salt that is at least 99.
15 How to Add Salt to the Pool CAUTION: Do not operate IntelliChlor with newly poured pool plaster; salt damage can occur. Wait at least 1 MONTH to allow new pool plaster to cure before operating IntelliChlor. 1. Switch on the pump to circulate the pool water. 2. Determine the amount of salt from the following charts. 3. Slowly pour in the salt around the outer perimeter of the pool for quick and even distribution.
