1GENERAL INFORMATIONSalt Chlorine Generator (SCG) OverviewThe iChlor Salt Chlorine Generator (SCG) uses a process known as electrolysis to produce chlorine gas whichimmediately dissolves into a solution to create Hypochlorite and Hypochlorous acid (a pool and spa water sanitizer)from a low concentration of salt added to the pool water. Hypochlorite and Hypochlorous kill bacteria, oxidizes organicmaterial, and kills algae, then reverts back to salt. The iChlor then reuses the salt and the process starts over again.The iChlor residential system is comprised of the iChlor cell and Power Center.Salt is an inherently corrosive material. While the levels of salt required for proper operationof the iChlor SCG are relatively low when compared to sea water and other salt solutions,placing any amount of salt in your pool increases the likelihood of corrosion or other deterioration of poolequipment and any surfaces used in and around your pool. Metal parts (including steel pools) and certain naturaland man-made surfaces are particularly susceptible to corrosion and deterioration when used in and aroundsalt water pools. Pentair Water Pool and Spa, Inc. (“Pentair”) does not represent or otherwise guarantee that theproper use of the iChlor SCG will prevent corrosion or other deterioration of pool equipment and any surfacesused in and around your pool. Consult your experienced pool professional, who should be able to advise youon the proper material selection, installation techniques for those materials, and the proper use, care andmaintenance of those materials for your specific pool type and location in order to minimize the corrosion anddeterioration that is inherent in and around salt water pools.The iChlor SCG is designed only to produce chlorine. The iChlor SCG does not monitoror control chlorine levels in the pool or spa water. It is the pool owner’s responsibility formonitoring and maintaining free chlorine levels at the APSP recommended range of 2.0 to 4.0 parts per million(ppm). It is the pool owner’s responsibility to check, on a regular basis, the free chlorine level while the pool pumpis running, and adjust the iChlor SCG accordingly.FOR ALL NEWLY CONSTRUCTED OR RESURFACED PLASTER POOLS: Do not operatethe iChlor SCG with newly poured or resurfaced pool plaster. Salt is a corrosive elementand severe salt damage can occur to your pool. Wait at least ONE (1) MONTH after construction to allowplaster to cure before adding salt and operating iChlor SCG. Follow the pool surface manufacturer’sguidelines for your specific pool. FOR NEW VINYL LINER POOLS, contact the manufacturer forrecommended guidelines before adding salt and operating the iChlor SCG.iChlor SCG ModelsAn iChlor Salt Chlorine Generator system consists of one or more of the following. Note: The output rating for thedifferent iChlor models is listed in the table below. These output ratings are based on 24 hours of run time.ModelPool Size:US Gallon (Liter)Chlorine Produced:lbs.

2Control Panel and Cell DescriptionThe iChlor Salt Chlorine Generator includes a control panel with buttons, LED indicators and a digital display tocontrol the iChlor and produce chlorine (see page 7). The iChlor measures the water temperature and salt level toproduce chlorine at the defined output. If the salt level in the pool water is too low, the cell is turned off until salt isadded to the pool. The SCG cell has a self-cleaning cycle which reverses the cell polarity, reducing calcium buildup.This feature turns the cell on and off at regular intervals to minimize calcium and scale buildup and further maximizescell life (see page 8).iChlor Salt Chlorine Generator (SCG)System ComponentsChlorine production can be varied by either adjusting the output level on the control panel or by varying thenumber of hours the iChlor is on each day. The unit automatically enters a cleaning cycle every few hours tohelp keep the cell free from calcium deposits. This process does not interrupt the production of chlorine. Flow Sensor: A flow sensor assures that there will always be adequate water flow through the iChlor.If the iChlor is not properly plumbed and/or does not receive adequate water flow, no chlorine will beproduced. Temperature Sensor: To protect the iChlor from potential damage when the temperature of the pool waterfalls below 52 F, 3 F (11 C, 1.67 C), the temperature sensor switches the iChlor off, illuminates theCELL light in RED, display “COLD” on the digital display, and no chlorine will be produced. Salt Sensor: Two (2) salt sensor probes in the iChlor are activated each time the iChlor needs to readthe salinity level of the pool water, which happens at power up, and again, every 2 hours of operation.However, only at power up, and after 12 hours of continues operation, will the salt level LED indicatorlights flash in a scrolling sequence for two (2) minutes, to indicate that the iChlor is in analysis mode.Note: After every salinity check, the LED indicator lights will show one (1) of the salinity ranges.For more information, see “Salt Level LEDs” on page 7.Note: The salt sensor reading is within /- 300 ppm accuracy.iCHLOR Salt Chlorine Generator Installation and User’s Guide

3Power CenterThe iChlor Salt Chlorine Generator power center converts AC electrical current to a low-voltage DC electrical currentwhich is required by the cell. The power supply should be connected with the pool circulation pump electrical sourceso that the iChlor only operates when the pool pump is on. The Power Center should be mounted vertically on thewall up to fifteen (15) feet away from the iChlor. The Power Center contains a transformer, fuse, connector to the celland the AC electrical current wiring configuration with the DC electrical current output cable to the iChlor. A fuse ismounted on the circuit board inside the enclosure for additional protection. There are no other controls or lights on thePower Center. For information about installing and proper use of the Power Center, see the “Power Center InstallationGuide,” (P/N 520590).CHLORINE GAS BUILDUPCAN OCCUR WITHIMPROPER WIRING: To reduce the risk ofpersonal injury the iChlor SCG Power Centermust be installed on an automation filter pumprelay wired to the load side of the time clock,electronically controlled switch, or relay loadside, so that it will receive power only when thepool pump is on. Otherwise, dangerous chlorinegas buildup can occur. The iChlor SCG shouldnever be energized when the pool pump is OFFand water is not flowing through the unit.Before pluggingor unplugging theiChlor SCG to the Power Center, firstswitch off the AC power to the PowerCenter.iChlor SCG Power Center(Model PC 100)iChlor 15 Power PackThe iChlor 15 Power Pack converts AC electrical current to a low-voltage DC electrical current which is required bythe cell. The Power Pack should be connected with the pool circulation pump electrical source so that the iChlor onlyoperates when the pool pump is on. A 15 ft. cord connected to the iChlor 15 unit plugs into the Power Pack whichplugs directly into a 110VAC outlet. The Power Pack can be mounted vertically on the wall up to fifteen (15) feet awayfrom the iChlor. The Power Pack contains a transformer, fuse (1.5 AMP 250 V, 3 AG), connector to the cell and the ACelectrical cord with plug. There are no other controls or lights on the Power Pack. The Power Pack must be connectedto a GFCI protected outlet.CHLORINE GAS BUILDUPCAN OCCUR WITH IMPROPERWIRING: To reduce the risk of personal injury theiChlor SCG Power Center must be installed on anautomation filter pump relay and wired to the loadside of the time clock, electronically controlledswitch, or relay load side, so that it will receivepower only when the pool pump is on. Otherwise,dangerous chlorine gas buildup can occur. The iChlorSCG should never be energized when the pool pumpis OFF and water is not flowing through the unit.First switch OFFAC power to thePower Pack before plugging in orunplugging the iChlor 15.iChlor 15 ExternalPower PackiCHLOR Salt Chlorine Generator Installation and User’s Guide

7CONTROL PANEL OVERVIEWiCHLOR SALT CHLORINE GENERATOR Salt Level LEDCERTIFIED TONSF/ANSI 50The iChlor SCG checks the pool water salinity regularly and displays the levels as follows: Green LED: Good salt. The pool water salt level is between 3000 ppm and 4500. Green LED (Flashing): Salt level is above 4500 ppm. The salt level is high which increases the risk ofcorrosion and deterioration of pool equipment and surfaces in and around the pool. Red LED: Low salt. The salt level is between 2600 ppm and 3000 ppm. The iChlor SCG will be producingchlorine at reduced efficiency. It is highly recommended to add salt. See (*) Note below. Red LED (Flashing) Very low salt. The salt level is between 2000 ppm and 2600 ppm. The iChlor SCGwill produce chlorine at a “reduced” output rate of approximate 25% less than output selection. It is highlyrecommended to add salt. See (*) Note below. Red LED (Flashing): Not enough salt. The salt level has fallen below 2000 ppm. The iChlor SCG will notproduce chlorine until salt is added. The iChlor SCG is OFF. See (*) Note below.Note (*): After every salt addition, pump should be allowed to run for at least 24 hours for proper dilution. Salinityreadings should only be taken, after the dilution period. Status LEDsCell: Shows the status of the iChlor. Green: iChlor is operating normally and producing chlorine.No Light: iChlor is off and not producing chlorine. It may be in an off-period of the sanitizing cycle andwill return on shortly.Red: iChlor is in “Standby” mode (system off, no chlorine production) due to a cold water condition. TheiChlor will resume to normal operation mode, including salinity report, once water temperature rises above52 F (11 C). In this mode, the display will read “COLD” to indicate the condition.Short Red Flash: Unit has detected a malfunction on the temperature sensor, and will indicate it withshort red flashes either while the cell is off (LED off), or while the cell is ON (Green LED). The unit willcontinue normal operation, but salinity indication might not be accurate until flow switch is replaced.Green (Flashing): iChlor needs to be inspected. The blades may have calcium buildup or any othercondition that cause a lack of conductivity. The iChlor is not producing chlorine.In this mode, the display will read “CELL” to indicate the condition.Flow: This light indicates the status of water flowing through the iChlor. Red: Insufficient water flow through the iChlor, no chlorine is being produced.Green: Sufficient water flow to produce chlorine.Short Flickering: Short flickering: iChlor is in communication with an IntelliFlo pump, and it is monitoringthe pump status. This short flickering will be present as long as there is communication with the pump,either with no flow (RED FLOW LED) or with good flow (GREEN FLOW LED).- Continue to Next Page iCHLOR Salt Chlorine Generator Installation and User’s Guide

8 Digital DisplayThe iChlor SCG Digital Display shows “output %” and cell polarity, during normal operation.To adjust output percentage:1. Press either LESS or MORE button.2. Output will begin to flash on the digital display. This indicates that the iChlor is ready for the user to changeoutput levels.3. While output is flashing, press LESS or MORE button, to change output in 1% increments.Note: Press and hold LESS or MORE button to change output in larger increments (5% jumps).4. Once the desired setting is programmed, and the user stops changing the setting, the digital display will stopflashing after a few seconds. This indicates the end of the adjustment mode and the iChlor will return to normaloperation.Cell polarity indicator:Cell polarity is displayed as a small rotating character on the left-side of the output % display. Clockwise rotation indicates Forward polarity on the blades. Counterclockwise rotation indicates Reverse polarity on the blades. Rotating feature also indicates chlorine production. If cell is OFF, character will not be displayed. More and Less Output ButtonsThe MORE and LESS buttons control the percentage of time that the iChlor SCG is producing chlorine while thepump is on.Note: When an iChlor is connected to a Pentair control system, the LESS and MORE buttons are disabled and iChlorSanitizer Output is controlled by the automation system. MORE Button: Increases the output of the cell in 1% increments up to 100%. LESS Button: Decreases the output of the cell in 1% decrements to 0%. Boost Mode On/Off: Press both the MORE and LESS buttons together to turn Boost Mode on or off. BoostMode sets the iChlor to run 100% for the next 24 hours of pool pump run time. If the time clock switches off thepump cycle, then switches power back on the next day, Boost Mode will continue until 24 hours has elapsedsince Boost Mode was turned on or Boost Mode is canceled by the user.In boost mode, the display will alternate between “100%” output and a 24 hour countdown timer indicating thetime left on boost mode.Self-CleaningThe self-cleaning feature reduces scale buildup on the blades of the iChlor SCG. The self-cleaning feature is factoryset to two (3) hours, and can be increased to four (4) or five (5) hours by the user.To adjust self-cleaning cycle duration:1. While the iChlor is ON, press and hold LESS Button until “3 Hrs” is displayed.2. Using the MORE or LESS Buttons, the cycle duration can be set to 3, 4 or 5 hours.iCHLOR Salt Chlorine Generator Installation and User’s Guide

9WATER CHEMISTRY, CONDITIONS AND PRECAUTIONSThis section describes the start-up procedure and operating instructions for iChlor SCG.The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in aridregions where pool water is subject to excessive evaporation and is not commonly dilutedwith fresh water. Dry acid can cause a buildup of by-products that can damage your chlorinator cell.Pool Water Chemistry, Conditions and Precautions1. New Pool Water: A recently filled or newly-refinished pool may contain undesirable matter. This undesirablematter could interfere with the ability of the iChlor SCG to produce chlorine properly. Make sure the water istested by a pool professional and properly balanced before switching on the iChlor SCG.Salt is an inherently corrosive material. While the levels of salt required for proper operation ofthe iChlor SCG are relatively low when compared to sea water and other salt solutions, placingany amount of salt in your pool increases the likelihood of corrosion or other deterioration of pool equipment andany surfaces used in and around your pool. Metal parts (including steel pools) and certain natural and man-madesurfaces are particularly susceptible to corrosion and deterioration when used in and around salt water pools.Pentair Water Pool and Spa (“Pentair”) does not represent or otherwise guarantee that the proper use of theiChlor SCG will prevent corrosion or other deterioration of
