• To reduce the risk of injury, do not permit children to use this product.
• CHLORINE GAS BUILDUP CAN OCCUR WITH IMPROPER WIRING: To reduce the risk of personal injury the iChlor Salt Chlorine Generator (SCG) Power Center/Pack must be installed on and wired to the load side of the time clock, electronically controlled switch, or relay load side so that it will receive power only when the pool pump is on. Otherwise, dangerous chlorine gas buildup can occur. The SCG should never be energized when the pool pump is OFF and water is not flowing through the SCG cell.
• To reduce the risk of injury, service should only be performed by a qualified pool service professional.
• Never operate the iChlor Salt Chlorine Generator (SCG) without proper flow or water circulation. A build-up of flammable gases will result in hazardous conditions.

CAUTION

• iChlor Salt Chlorine Generator (SCG) is intended for use with permanently installed pools and may also be used with hot tubs and spas if so marked. Do not use storable or steel pools. A permanently installed pool is constructed in or on the ground, or in a building such that it cannot be readily disassembled for storage. A storable pool is constructed so that it is capable of being readily disassembled for storage and reassembled to its original integrity.
• When using the iChlor Salt Chlorine Generator (SCG) with a Pentair Control System, always wire the iSCG Power Center/Pack to the pump side of the relay located in the control system load centre. This wiring method does not require a ground fault circuit interrupter (GFCI) to protect the circuit. A green-coloured terminal (or a wire connector marked “G”, “GR”, “Ground” or “Grounding”) is provided within the terminal compartment in the power centre enclosure. To reduce the risk of electric shock, connect this terminal or connector to the grounding terminal of your electric service or supply panel with a conductor equivalent in size to the circuit conductors supplying this equipment. The power supply must be interconnected with the pool pump motor power source. This ensures the SCG and pool pump will switch on and off together.

WARNING

• Salt is an inherently corrosive material. While the levels of salt required for proper operation of the salt chlorine generator (SCG) are relatively low when compared to seawater and other salt solutions, placing any amount of salt in your pool increases the likelihood of corrosion or deterioration of pool equipment and any surfaces used in and around your pool. Metal parts (including metal pools) and certain natural and man-made surfaces are particularly susceptible to corrosion and deterioration when used in and around saltwater pools. Pentair does not represent or otherwise guarantee that the proper use of the (SCG) will prevent corrosion or deterioration of pool equipment and any surfaces used in and around your pool. Consult your experienced pool professional, who should be able to advise you on the proper material selection, installation techniques, and the proper use, care and maintenance of those materials for your specific pool type and location to minimize the corrosion and deterioration that is inherent in and around saltwater pools.

CAUTION

• Use of chemicals other than those recommended may be hazardous. Even proper use of the recommended chemicals can be hazardous. Follow the Chemical Manufacturer’s Instructions.
• To reduce the risk of electric shock, install the iChlor Salt Chlorine Generator (SCG) a minimum of 5 ft. (1.5 m) away from the inside wall of the pool.
• Install the iChlor SCG a minimum of 3 ft. (0.9 m) away from the heater outlet.
• A solid copper, bonding conductor no smaller than No. 8 AWG (8.4 mm) should be connected from the accessible wire connector on the unit to all metal parts of the swimming pool, spa, or hot tub structure and all electrical equipment, metal conduit, and metal piping within 5 ft. (1.5 m) of the inside walls of a swimming pool, spa, or hot tub when the unit is installed within 5 ft. (1.5 m) of the inside walls of the swimming pool, spa, or hot tub.

GENERAL INFORMATION

Salt Chlorine Generator (SCG) Overview
The iChlor® Salt Chlorine Generator (SCG) uses a process known as electrolysis to produce chlorine gas which immediately dissolves into a solution to create Hypochlorite and Hypochlorous acid (a pool and spa water sanitiser) from a low concentration of salt added to the pool water. Hypochlorite and Hypochlorous kill bacteria, oxidize organic material, and kill algae, then revert to salt. The iChlor then reuses the salt and the process starts over again. The iChlor system is comprised of the flow cell and power supply/pack.

WARNING AND CAUTION

• Salt is an inherently corrosive material. While the levels of salt required for proper operation of the iChlor salt chlorine generator (SCG) are relatively low when compared to seawater and other salt solutions, placing any amount of salt in your pool increases the likelihood of corrosion or deterioration of pool equipment and any surfaces used in and around your pool. Metal parts (including metal pools) and certain natural and man-made surfaces are particularly susceptible to corrosion and deterioration when used in and around saltwater pools. Pentair does not represent or otherwise guarantee that the proper use of the SCG will prevent corrosion or deterioration of pool equipment and any surfaces used in and around your pool. Consult your experienced pool professional, who should be able to advise you on the proper material selection, installation techniques, and the proper use, care and maintenance of those materials for your specific pool type and location to minimize the corrosion and deterioration that is inherent in and around saltwater pools.
• The iChlor SCG is designed only to produce chlorine. The iChlor SCG does not monitor or control chlorine levels in the pool or spa water. It is the pool owner’s responsibility to monitor and maintain 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, regularly, the free chlorine level while the pool pump is running, and adjust the iChlor SCG accordingly.
• FOR ALL NEWLY CONSTRUCTED OR RESURFACED PLASTER POOLS: Do not operate the iChlor SCG with newly poured or resurfaced pool plaster. Salt is a corrosive element and severe damage can occur to your pool. Wait at least ONE (1) MONTH after construction to allow the plaster to cure before adding salt and operating iChlor SCG. Follow the pool surface manufacturer’s guidelines for your specific pool. FOR NEW VINYL LINER POOLS, contact the manufacturer for recommended guidelines before adding salt and operating the iChlor SCG.

Control Panel and Cell Description
The iChlor® Salt Chlorine Generator includes a control panel with buttons, LED indicators and a digital display to control the iChlor and produce chlorine (see page 7). The iChlor measures the water temperature and salt level to produce chlorine at the defined output. If the salt level in the pool water is too low, the cell is turned off until salt is added to the pool. The SCG cell has a self-cleaning cycle which reverses the cell polarity every few hours. This feature turns the cell on and off at regular intervals to minimize calcium and scale buildup and further maximize cell life (see page 8).

System Components
Chlorine production can be varied by either adjusting the output level on the control panel or by varying the number of hours the iChlor is on each day. The unit automatically enters a cleaning cycle every few hours to help 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 be produced.

• Temperature Sensor : To protect the iChlor from potential damage when the temperature of the pool water falls below 52° F, ±3° F (11° C, ±1.67° C), the temperature sensor switches the iChlor off, illuminates the CELL 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 read the 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 continuous operation, will the salt level LED indicator lights 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.

Chloe 30 Power Center
The iChlor® Salt Chlorine Generator power centre converts AC to the low- voltage DC required by the cell. The power centre should be connected to the pool circulation pump electrical source so that the iChlor only operates when the pool pump is on. The Power Center should be mounted vertically on the wall up to 15 ft. (4.6 m) away from the iChlor. The power centre contains a fuse mounted on the circuit board inside the enclosure for additional protection. For information about installation and proper use of the Power Center, see “Power Center Installation Guide” (P/N 520590).

WARNING

CHLORINE GAS BUILDUP CAN OCCUR IF IMPROPERLY WIRED: To reduce the risk of personal injury the iChlor SCG Power Center must be installed on an automation filter pump relay wired to the load side of the time clock, electronically controlled switch, or relay load side, so that it will receive power only when the pool pump is on. Otherwise, dangerous chlorine gas buildup can occur. The iChlor SCG should never be energized when the pool pump is OFF and water is not flowing through the unit.

CAUTION
Switch OFF power to the Power Center before plugging in or unplugging the iChlor.

Chloe 15 Power Pack
The iChlor 15 Power Pack converts AC to the low-voltage DC required by the cell. The Power Pack should be connected to the pool circulation pump electrical source so that the iChlor only operates when the pool pump is on. A 15 ft. (4.6 m) cord connected to the iChlor 15 unit plugs into the Power Pack which plugs directly into a 110VAC outlet. The Power Pack can be mounted vertically on the wall up to 15 ft. (4.6 m) away from the iChlor and contains a fuse mounted on the circuit board inside the enclosure for additional protection. The Power Pack must be connected to a GFCI-protected outlet.

WARNING

CHLORINE GAS BUILDUP CAN OCCUR IF IMPROPERLY WIRED: To reduce the risk of personal injury the iChlor SCG Power Center must be installed on an automation filter pump relay and wired to the load side of the time clock, electronically controlled switch, or relay load side, so that it will receive power only when the pool pump is on. Otherwise, dangerous chlorine gas buildup can occur. The iChlor SCG should never be energized when the pool pump is OFF and water is not flowing through the unit.

CAUTION
Switch OFF power to the Power Pack before plugging in or unplugging the iChlor.

Installation Requirements and Recommendations
The system diagram below shows a typical iChlor® SCG system installation.

Note: Refer to the relevant portions of this Installation and User’s Guide for information regarding the proper placement and spacing of all equipment depicted in the diagram. The diagram is not drawn to scale.
Install Chlorine/Bromine Feeders after the iChlor Cell

CAUTION
To avoid permanent damage to the iChlor SCG cell, in-line chlorine/bromine feeders (such as  Pentair Rainbow® models) MUST be installed AFTER the iChlor SCG cell as shown below.  When using the iChlor SCG with an in-floor cleaning system, it is recommended that a separate return line be used for the cleaner to reduce the increased water pressure stress on the iChlor cell.

Loop Plumbing Diagram

The iChlor® SCG is designed to operate with water flow rates from 20 to 105 gpm (75 to 397.5 lpm). Refer to the pipe manufacturer’s specifications for the recommended maximum flow rate. For flow rates over 80 gpm (302.8 lpm), you must use a bypass loop (as shown below) for best chlorine production. Installations with flow rates over 80 gpm (302.8 lpm) include those that have in-floor cleaning systems or booster pumps. These systems MUST use a bypass loop with the iChlor with a flow control valve that assures that the flow through the iChlor is maintained within its designed operating water flow rates.

Pool Water Preparation

Determining Pool Size (Gallons of Water in Your Pool)

• Rectangular Pools : Length x width x average depth x 7.5
• Circular Pools : Diameter x diameter x average depth x 5.9
• Oval Pools : Length x width x average depth x 6.7
• Sloping Sides : Multiply total gallons by 0.85 = gallon capacity

Determining Pool Size (litres of water in your pool)

• Rectangular Pools : Length x width (meters) x average depth x 1000
• Circular Pools : Diameter x diameter x average depth x 785
• Oval Pools : Length x width (meters) x average depth x 893
• Sloping Sides : Multiply total litres by 0.85 = litre capacity.

CAUTION
Never use dry acid (sodium bisulphate) 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 iChlor SCG.

CONTROL PANEL OVERVIEW

Salt Level LED
The 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 of corrosion and deterioration of pool equipment and surfaces.
• Red LED : Low salt. The salt level is between 2600 ppm and 3000 ppm. The iChlor SCG will be producing chlorine 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 SCG will produce chlorine at a “reduced” output rate of approximately 25% less than the output selection. It is highly recommended to add salt. See Note below.
• Red LED (Flashing): Not enough salt. The salt level has fallen below 2000 ppm. The iChlor SCG will not produce chlorine until salt is added. The iChlor SCG is OFF. See Note below.

Note: After every salt addition, the pump should be allowed to run for at least 24 hours for proper dilution. Salinity readings should only be taken, after the dilution period.

Status LEDs

Cell: 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 and will return shortly.
• Red: Chloe is in “Standby” mode (system off, no chlorine production) due to a cold water condition. The iChlor will resume to normal operation mode, including a salinity report, once water temperature rises above 52° F (11° C). In this mode, the display will read “COLD” to indicate the condition.
• Short Red Flash : The unit has detected a malfunction on the temperature sensor, and will indicate it with short red flashes either while the cell is off (LED off), or while the cell is ON (Green LED). The unit will continue normal operation, but the salinity indication might not be accurate until the flow switch is replaced.
• Green (Flashing): iChlor needs to be inspected. The blades may have calcium buildup or any other condition that causes 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 monitoring the 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).

Digital Display
The iChlor SCG Digital Display shows “output %” and cell polarity, during normal operation.

To adjust output percentage:

1. Press either the LESS or MORE button.

2. The output will begin to flash on the digital display. This indicates that the iChlor is ready for the user to change output levels.

3. While output is flashing, press the LESS or MORE button, to change output in 1% increments.
   Note: Press and hold the 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 stop flashing after a few seconds. This indicates the end of the adjustment mode and the iChlor will return to normal operation.

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 the cell is OFF, the character will not be displayed.

More and Less Output Buttons
The MORE and LESS buttons control the percentage of time that the iChlor SCG is producing chlorine while the pump is on.

Note: When an iChlor is connected to a Pentair control system, the LESS and MORE buttons are disabled and iChlor Sanitizer 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 by 1% decrements to 0%.
• Boost Mode On/Off : Press both the MORE and LESS buttons together to turn Boost Mode on or off. Boost Mode sets the iChlor to run 100% for the next 24 hours of pool pump run time. If the time clock switches off the pump cycle and then switches power back on the next day, Boost Mode will continue until 24 hours have elapsed since Boost Mode was turned on or Boost Mode is cancelled by the user.
  In boost mode, the display will alternate between “100%” output and a 24-hour countdown timer indicating the time left on boost mode.

Self-Cleaning
The self-cleaning feature reduces scale buildup on the blades of the iChlor SCG. The self-cleaning feature is factory set to two (3) hours and can be increased to four (4) or five (5) hours by the user.

To adjust the self-cleaning cycle duration:

1. While the iChlor is ON, press and hold the 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.

WATER CHEMISTRY, CONDITIONS AND PRECAUTIONS

This section describes the start-up procedure and operating instructions for iChlor® SCG.

CAUTION
The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in arid regions where pool water is subject to excessive evaporation and is not commonly diluted with fresh water. Dry acid can cause a buildup of by-products that can damage your chlorinator cell.

Pool Water Chemistry, Conditions and Precautions

1. New Pool Water: A recently filled or newly refinished pool may contain undesirable matter. This undesirable matter could interfere with the ability of the iChlor SCG to produce chlorine properly. Make sure the water is tested by a pool professional and properly balanced before switching on the iChlor SCG.
   WARNING
   Salt is an inherently corrosive material. While the levels of salt required for proper operation of the salt chlorine generator (SCG) are relatively low when compared to seawater and other salt solutions, placing any amount of salt in your pool increases the likelihood of corrosion or deterioration of pool equipment and any surfaces used in and around your pool. Metal parts (including metal pools) and certain natural and man-made surfaces are particularly susceptible to corrosion and deterioration when used in and around saltwater pools. Pentair does not represent or otherwise guarantee that the proper use of the (SCG) will prevent corrosion or deterioration of pool equipment and any surfaces used in and around your pool. Consult your experienced pool professional, who should be able to advise you on the proper material selection, installation techniques, and the proper use, care and maintenance of those materials for your specific pool type and location to minimize the corrosion and deterioration that is inherent in and around saltwater pools.

2. Superchlorination burns out the swimmer waste that has been combined with chlorine. This frees the chlorine for sanitizing. This is accomplished by raising the chlorine level quickly and dramatically. When the chlorine level is raised to ten (10) times the amount of combined chlorine the pool water is said to have been super chlorinated. As pool water is continuously passed through the iChlor SCG while the unit is powered on, the water inside the iChlor is super chlorinated.
   Note: On initial start-up of a pool, it is best to super chlorinate using an outside source, i.e., use a shock treatment available at your local pool supplier.

3. Chloramines should not be present in pool water. Chloramines are formed when ammonia (which is found in urine and sweat) combines with free chlorine. This ties up the free chlorine in your pool and does not allow the chlorine in your pool to disinfect. Chloramines also burn the eyes and are foul-smelling. Super Chlorinate to remove chloramines at the initial start-up of the pool and as needed to maintain proper levels of free chlorine.

4. Cyanuric acid is needed in outdoor pools to help stabilize and maintain proper levels of chlorine. 90% of un-stabilized chlorine is destroyed by the UV radiation from the sun within two hours. Cyanuric acid stabilizes chlorine in water from UV degradation. When using the iChlor, the cyanuric acid level should be maintained between 30-50 ppm. See Table 2, on page 14. NOTE: DO NOT USE CYANURIC ACID IN INDOOR POOLS.

5. 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 to the iChlor system. The individual performing the TDS test (see page 12) may then subtract the salinity level to arrive at a TDS level that would be compatible with a TDS reading for a non-salt water pool.

6. Metals – Some metals, i.e. copper and iron, can cause loss of chlorine. Also, metals can stain your pool. Metals can also damage the iChlor SCG. Have your local pool professional check for metals and recommend methods of removal.

7. Nitrates and Phosphates 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. Your local pool professional can test for nitrates and phosphates. While a 0 ppm level of nitrates is ideal, the pool owner should make sure that nitrates DO NOT exceed 10 ppm. Phosphates should not exceed 125 parts per billion (ppb).

Optimum Pool Water Chemistry Conditions for Salt Water Pools (using the iChlor SCG)
By the Association of Pool and Spa Professionals (APSP) standards, it is recommended that the following pool water chemistry conditions be maintained on an ongoing basis to help protect pool users, pool-related equipment and surfaces in and around the pool. These values are important to maintaining the pool equipment in proper operating condition and preventing corrosion. For more information, refer to your local agency having jurisdiction, NSPI (National Spa and Pool Institute), the CDC (Centers for Disease Control), or the WHO (World Health Organization).

Chlorine Testing
It is recommended that chlorine test samples be taken from two (2) locations in the pool. Compare the samples. A higher level should be found at the pool return line. The higher level at the pool return line indicates the iChlor® SCG is producing chlorine. Take chlorine samples for testing at:

• The pool return line
• 18 inches (45.7 cm) below the surface and well away from the pool return line

What Type of Salt to Use?
Use salt that is at least 99.8% pure NaCl, and sodium chloride. The preferred and recommended salt is an evaporated, granulated, food-quality, non-iodized salt with no additives. Consult your salt supplier.

• Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS or yellow prussiate of soda). Filling agents can cause some discolouration of fittings and surface finishes in the pool.
• Water conditioning salt pellets are compressed forms of evaporated salt and may be used, but will take longer to dissolve. Such pellets could damage pool plaster and other surfaces in and around the pool.
• Do not use calcium chloride or potassium chloride as a source of salt. (Use sodium chloride only).
• Do not use Rock salt (insoluble impurities mixed with the rock salt can shorten the life of the iChlor.

How Much Salt to Use?

CAUTION
FOR ALL NEWLY SURFACED PLASTER POOLS: Do not operate the iChlor SCG with newly surfaced pool plaster. Salt is a corrosive element and severe salt damage can occur to your pool. Wait for at least ONE (1) MONTH after construction to allow the plaster to cure before adding salt and operating iChlor SCG. Follow the pool surface manufacturer’s guidelines for your specific pool. FOR NEW VINYL LINER POOLS, contact the manufacturer for recommended guidelines before adding salt and operating the iChlor SCG.

Use Table 2 (page 14) to determine how much salt will be needed. Most pools contain some salt, depending on the water source and chemicals used for sanitizing. Therefore, the pool owner must always test salt levels before adding salt. A handheld meter calibrated for NaCl (salt) can be used to determine the salt levels of the water. After the iChlor SCG is powered on, the LED salt level lights will blink from bottom to top for two (2) minutes while it analyzes the pool water, and then the LED indicators will show one (1) of four (4) salt level ranges. See Salt Status LEDs on page 7 for more information.

• 3600 ppm of salt is recommended for optimum water conditions.
• Low salt concentration below 3000 ppm will reduce operating efficiency.
• Low salt concentration below 2600 ppm will cause the unit to reduce production.
• Low salt concentration below 2000 ppm will cause the unit to turn OFF.
• High salt concentrations above 4500 ppm may cause excessive corrosion or deterioration to pool equipment and surrounding surfaces in and around the pool.

Note: Salt measurements will vary between measuring devices (salt test strips, electronic testers, and titration). The salt sensor reading is within +/- 300 ppm accuracy. For more troubleshooting information about high salt levels, see Troubleshooting on page 28.

Calculating the Saturation Index
The saturation index is a formula that measures a solution’s ability to dissolve or deposit calcium carbonate and is used as an indicator of the corrosivity of the solution and temperature. A well-balanced water will have a formula result ranging between -0.3 and +0.3 Outside this range, the pool water is considered out of balance, potentially damaging pool equipment or scaling the iChlor SCG. The equation to calculate Si is:

Cyanuric acid in the form of cyanurate ions contributes to alkalinity. Thus, a correction must be made to total alkalinity. We subtract 1/3 of the cyanuric acid level from the reading obtained in the total alkalinity test.

Total Alkalinity – 1/3 Cyanuric Acid = Corrected Alkalinity

This correction can be considerable in established pools with high cyanuric acid levels; for example, at 100 ppm cyanuric acid, the correction amounts to 33 ppm (100 ÷ 3 = 33.3).

TDS Factor
Factors shown to the right are based on the actual measured value for the particular parameter.

Langelier Saturation Index Factors

Note: Use the reading closest to your actual reading in choosing the factor. Total alkalinity in this context refers to the total of carbonate and bicarbonate alkalinity. If cyanuric acid is used, a correction factor must be used (see cyanuric acid Table 1).

CAUTION
FOR ALL NEWLY SURFACED PLASTER POOLS: Do not operate the iChlor® SCG with newly surfaced pool plaster. Salt is a corrosive element and severe salt damage can occur to your pool. Wait for at least ONE (1) MONTH after construction to allow the plaster to cure before adding salt and operating iChlor SCG. Follow the pool surface manufacturer’s guidelines for your specific pool. FOR NEW VINYL LINER POOLS, contact the manufacturer for recommended guidelines before adding salt and operating the iChlor SCG.

1. Check the salt level in the water before adding any salt to the pool.
2. Determine the amount of salt from the following chart.
3. Slowly pour the salt around the outer perimeter of the pool for quick and even distribution. To avoid clogging the filter or damaging pool-related equipment and surrounding surfaces, do not add salt through the skimmer or surge tank.
4. Brush the pool bottom and allow water to circulate for 24 hours to dissolve salt completely.
5. After 24 hours, verify the correct salt level reading by checking the LED indicators on the iChlor and by a separate reliable test method.
6. Power on the iChlor SCG and set the Sanitizer Output level to the proper setting to maintain the appropriate free chlorine levels in the pool water (i.e., within the 2.0 – 4.0 ppm, APSP recommended range).

DANGER
RISK OF ELECTRIC SHOCK, WHICH CAN RESULT IN SERIOUS INJURY OR DEATH. Before attempting installation or service, ensure that all power to the circuit supplying power to the system is disconnected/turned off at the circuit breaker. It is recommended, but not mandatory that the iChlor Power Center be connected to a circuit protected by a ground fault circuit interrupter (GFCI). When using electrical products, basic precautions should always be followed, including the following:

• Grounding (earth bonding) is required. The unit should be installed by a qualified service person and grounded.
• Install to allow access to cell buttons and power centre.
• Read Safety Precautions and Important Instructions (pages i and ii). Before attempting any electrical wiring, be sure to read and follow Safety Instructions. Wiring should only be performed by a qualified professional.
• Install the iChlor unit a minimum of 3 ft. (0.9 m) away from the heater outlet.
• Pipe couplings: Schedule 80, maximum pressure 50 psi at 70° F (21° C).
• Operate the unit with a minimum flow of 20 gpm. For high-flow applications (higher than 80 gpm), use a bypass loop (see page 5) for best flow sensing.
• Provide at least 12 – 18 in. (30.5 – 45.7 cm) of straight pipe in front of the cell inlet.

Chloe SCG Spacer Cell
After new pool construction has been completed, to prevent debris from entering the iChlor® SCG, it is recommended that the iChlor SCG spacer cell (P/N 522965) be installed before installing the iChlor SCG. After the pool system has flushed the debris from the pipes, remove the spacer cell and install the iChlor SCG.

Installing the iChlor Cell Assembly
Install the iChlor cell assembly no closer than 3 ft. (0.9 m) away from the heater outlet, if used. For more information see plumbing diagrams on pages 4 and 5.

Note: For best flow sensing, provide at least 12 – 18 in. (30.5 – 45.7 cm) of straight pipe in front of the cell inlet.

Note: After new pool construction has been completed, to prevent debris from entering the iChlor cell assembly, it is recommended that the iChlor SCG spacer cell (P/N 522965) be installed before installing the iChlor SCG cell. After the pool system has flushed the debris from the pipes, remove the spacer cell and install the iChlor cell.

Note: Pipe couplings: Schedule 80, maximum pressure 50 psi at 70° F (21° C).

To install the iChlor SCG Cell:

1. Using the cut-out template provided with the iChlor, measure how much plumbing will have to be removed to install the cell. Cut the plumbing accordingly.

2. Using PVC glue, mount the PVC couplings to the plumbing pipe. Allow the glue to dry.

3. Mount the cell vertically if possible. Allow access to the cell operator control panel. Install the cell onto the couplings. Ensure the O-rings are seated properly.
   Note: Ensure that the cell has been installed so that there is proper direction of flow through the cell. Refer to the flow direction marking on the side of the iChlor cell.

4. Start the pump and visually inspect for leaks around the couplings.

Connecting the iChlor Cell Power Cable to the Power Center
After the cell installation is completed, connect the iChlor SCG cell’s power cable to the Power Center:

WARNING
Switch OFF the main system power to the Power Center before making any connections.

1. Be sure that AC power is switched OFF before connecting the power cord to the Power Center or the cell may short circuit.
2. Align the four (4) pins of the cell power cord connector with the socket on the bottom of the Power Center and insert the connector. Turn the round socket nut until it locks the connector in place.

Wiring AC Power from iChlor (SCG) and IntelliFlo® pump to IntelliTouch®, EasyTouch® and SunTouch® Control System

When using the iChlor SCG and an IntelliFlo pump (or 2-speed pump) with an IntelliTouch, EasyTouch or SunTouch Control System, the iChlor AC power center wires must be connected to the LOAD SIDE OF THE FILTER PUMP RELAY located in the Load/Power Center (see diagram below). This ensures that the iChlor SCG cell produces chlorine only when the main filter pump is on. This method does not require a ground fault circuit interrupter (GFCI) to protect the circuit.

Note: For non-automation control systems using a time clock, see page 32 for wiring information.

OPERATION

This section describes the start-up procedure and operating instructions for iChlor® SCG. Before starting up and operating the iChlor SCG, the pool in which the iChlor SCG will be used must have been completed and filled with water for at least one (1) month (for plaster pools) and the pool water salt level must be stable and being maintained at 3600 ppm.

Chloe Operation

IMPORTANT! Use of an external Pool Pump Timer is NOT Required The iChlor is designed to supply a sufficient amount of chlorine to sanitize pool water daily. If the pool pump is continuously running and the iChlor is operated 24 hours a day at 100%, more chlorine would be generated than would be needed by most pools (2-4 ppm, per APSP recommendations). The iChlor has its internal timer which cycles the electrolytic cell on and off depending on what per cent the Sanitizer Output is set. For instance, at 100% the cell works all the time while the pool pump is running. When set at 80%, the cell is allowed to rest 20% of the time while the pool pump is running prolonging cell life. To fine- tune iChlor to your pool size just increase or decrease the Sanitizer Output from 1% to 100% of the time. For more information, see Output Buttons on.

• The iChlor SCG is designed to only produce chlorine. The iChlor SCG does not monitor or control chlorine levels in the pool or spa water. It is the pool owner’s responsibility to monitor and maintain free chlorine levels at 2.0 to 4.0 parts per million (ppm) according to APSP recommendations.
• Before attempting to operate iChlor refer to General Recommendations and General Cautions on page 24, and Pool Water Preparation on.

If Using a Pool Pump Timer
The Association of Pool and Spa Professionals (APSP) recommends that all water in a residential pool pass through the filtration system at least once every six (6) hours, four (4) turns every 24 hours (referred to as pool water turnover). However, many factors affect actual pump and filter system run times. Pool size, source of water, direct sunlight, indoor/outdoor, screened/unscreened, filtration system, cold or hot weather, swimmer load, rain, organic debris, algae, etc., are all factors which contribute to either more or less pool pump and filter system run times. Because of these differences, it is extremely difficult to set a standard initial run time (starting point) for the pool pump and chlorinating system. Try initially setting the pool pump timer to twelve (12) hours. It will take a few days to achieve the correct amount of pool pump operating time. When iChlor® SCG is wired with a pool pump timer results will vary greatly from one pool installation to the next, so this should be discussed with your pool professional.

The key points are:

• Operate the pool pump for at least the minimum time needed for good filtration and adequate chlorine production by the iChlor SCG, according to your pool professional’s recommendations.
• While pool pump timers can reduce energy consumption, the pool pump must be running for the iChlor SCG to produce chlorine and must remain running long enough to maintain proper chlorine levels (i.e., 2.0 – 4.0 ppm of free available chlorine).

Note: Exception – For Cold Weather Operation: The unit turns off in water temperatures of 52° F, ±3° F (11° C, ±1.67° C) and below, and will not produce chlorine. This feature extends the life of the cell.

Start-up Procedure (Super Chlorination)
Super Chlorination is recommended before pool start-up. Start with clean, properly chlorinated, pool water from the beginning. The iChlor® SCG will build up a sufficient level of chlorine for sanitation in several hours. However, if the pool water has a high demand from start-up the iChlor will not be able to produce enough chlorine to reach break-point chlorination. So, it is best to super chlorinate using an outside source at the time of pool start- up. Then, wait until the chlorine level has returned to 2.0 to 4.0 ppm before switching on the iChlor.

Sanitizer Output Settings and Adjustments

• Switch on the pool pump switch or pool pump timer. The salt display will blink both LEDs (bottom to top) for two (2) minutes, indicating that it has not checked the salt level yet. After two (2) minutes, the salt will be checked and one (1) of the salt level LEDs will be displayed. If the salinity is below 2600 ppm, the salt display will light the red LOW SALT indicator, and the CELL light will go blank, indicating there is not enough salt in the pool for chlorine to be produced.
• Set the Sanitizer Output to 60% by pressing the MORE or LESS button (see page 8).
• After 24 hours, use a reliable test method to test the pool water for free available chlorine. The ideal range to maintain is 2.0-4.0 ppm. If the free chlorine level of the pool water is too low, increase iChlor run time by pressing the MORE button. If the free chlorine level of the pool water is too high, decrease iChlor run time by pressing the LESS button.
• Due to a varying free chlorine demand of pool water, it may take a few days to determine the number of daily pool operating hours and the “Sanitizer Output” percentage setting (see page 8) for your pool. Continue adjusting as necessary, allowing 24 hours between adjustments until the free chlorine level of the pool water is stabilized at 2.0 – 4.0 ppm, per APSP recommendations.

Operating in Winter
The Chloe SCG switches off and will not produce chlorine in water temperatures of 52° F, ±3° F (11° C, ±1.67°C) and below. This feature extends the life of the iChlor SCG. See Winterizing on page 27.

General Recommendations

• After new pool construction has been completed, before installing the iChlor SCG, install the iChlor Spacer Cell (P/N 522965) to remove debris from the pipes for thirty (30) days and to allow sufficient time for the pool plaster (or other similar material) to properly cure and seal.
• Read and keep this Installation and User’s Guide in a safe place.
• Increase Sanitizer Output level as necessary after heavy rain (outdoor pools) and return to normal afterwards.
• Increase Sanitizer Output level when air and water temperatures rise.
• Increase the Sanitizer Output level when the number of pool users increases.
• Use Cyanuric Acid ONLY as necessary to stabilize chlorine in outdoor pools. NOTE: DO NOT USE CYANURIC ACID IN INDOOR POOLS.
• Once a month take a pool water sample to a pool professional for a complete analysis.

General Cautions

• Do not get fertilizer in your pool. Fertilizers contain nitrates, which cause a high chlorine demand.
• Never use dry acid to adjust pH in arid geographic areas with excessive evaporation and minimal dilution. A buildup of by-products can damage the iChlor SCG.
• Do not add any pool water-balancing chemicals (including salt) unless the iChlor SCG is switched off.
• Do not let the Cyanuric Acid level drop below 30 ppm in outdoor pools. DO NOT USE CYANURIC ACID IN INDOOR POOLS.

MAINTENANCE

Weekly Service

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 bisulphate) to adjust pH in arid geographic areas with excessive evaporation and minimal dilution. A buildup of byproducts can damage the iChlor SCG.

2. 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.

3. Chlorine Test: Test the pool water for free chlorine level with a reliable test method. Maintain the ideal range by adjusting the iChlor SCG Sanitize Output settings. See Output Buttons on page 8.

   • Desired 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 two (2) places in the pool, one at the pool return line, and 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 iChlor SCG 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.

1. Salt Level Test: Check the salt display lights on the unit and check that the green “GOOD” light is on and is not flashing.
   • If the red LOW LED salt light is on. Add salt to the pool water (see charts beginning on page 13).
   • If the salt level does not rise after 24 hours, see Troubleshooting on page 28. To access salinity information through Diagnostic Mode: Press and hold the MORE button for three (3) seconds until the lights scroll across the unit. This means the iChlor has entered Diagnostic Mode. Scroll through the screens using the MORE button until the salinity screen is displayed.
2. Pool Water Sample: Take a sample of the pool water to your local pool store for testing.
3. Cyanuric Acid: Sample the pool water and test for cyanuric acid level using a reliable test method. When using the iChlor SCG the recommended ideal cyanuric acid level is 30-50 ppm.
4. Calcium Hardness: Test pool water for calcium hardness level using a reliable test method. If necessary, adjust according to your pool professional’s recommendations. APSP’s recommended ideal range for calcium is 200 to 400 ppm for pools.
5. Metals Test: It is recommended that the pool water be sampled and tested periodically for the presence of metals such as copper, iron, and manganese. These metals can damage the iChlor SCG and other related pool equipment and should not be present in the pool water. If those metals are present, contact your pool professional.
6. TDS (Total Dissolved Solids): Test pool water for TDS level using a test kit or by having a water sample tested by a pool professional. If necessary, adjust according to your pool professional’s recommendations. APSP standard of 3000 minimum to 6000 maximum ppm (which includes the salt) is recommended for salt pools.

Usage Hours Meter
The iChlor® SCG provides a built-in cell “hours used” meter that reports how many hours iChlor has been operating. The iChlor SCG is designed to operate for approximately 10,000 hours before replacement is needed or roughly five (5) years of average use.

To access the usage meter through Diagnostic mode:
Press and hold the MORE button for three (3) seconds until the lights scroll across the unit. The iChlor SCG will enter its diagnostic mode, showing hours of operation on the display.

Cleaning the Cell Blades

1. Automatic Cleaning: The iChlor has an automatic cell blade cleaning feature that helps remove scale deposits from the iChlor blades. 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 scholar blades show excessive scaling, you need to perform an acid wash cleaning. Proceed to “Acid Wash Cleaning,” Step 2.
   Note: Before acid washing, remove the loose calcium in the cell: Use a garden hose on the jet setting and spray directly into both ends of the cell. Most of this calcium buildup has a slushy consistency and will be blown out of the cell. Once the majority of the calcium has been removed, continue with acid washing which will now be more effective since most of the calcium has been removed.

2. Acid Wash Cleaning: If the iChlor blades show a tendency to scale, it is recommended that every two (2) months the iChlor be removed and inspected for scale formation and/or debris on the iChlor blades. High-hardness areas may require more frequent cleaning. Some filters allow debris to pass through to the iChlor, possibly lodging between the blades. A small amount of scale formation is normal. If by looking through the iChlor it is observed that there is excessive scale formation between the blades or debris is present, the scholar must be cleaned as follows:

   • Use a high-pressure jet of water from a garden hose. If the blades cannot be reasonably cleaned in this manner, acid cleaning is necessary.
   • To acid clean the iChlor SCG blades: Turn off power to the Power Center, then disconnect the iChlor SCG from the Power Center.
   • Create a 1 to 4-part solution of acid and water. Mix one (1) quart of muriatic acid with one (1) gallon of tap water in a plastic bucket.
     Note: The iChlor® SCG Acid Cleaning Kit (P/N 523103) provides an acid washstand for the iChlor SCG to allow the diluted acid solution to be poured into the iChlor SCG to immerse the blades for cleaning.

WARNING

• Screw the acid wash stand onto the threaded end of the iChlor cell, making sure the O-ring is properly installed on the acid wash stand (the acid wash stand and O-ring are provided with the acid wash kit [P/N 523103]). Place the iChlor vertically in a five (5) gallon bucket. Pour the acid solution (as described in step c) into the iChlor until the cell blades are covered. Allow the acid solution to bubble, and clean the blades. Note: The acid should only be contained inside the iChlor covering the blades. Try not to spill the acid on the outside of the iChlor. If acid does spill on the outside of the iChlor, rinse it off with water. A foaming action will begin, which is caused by scale (calcium carbonate) being dissolved from the blades. If rigorous foaming action does not begin, the blades do not need to be cleaned (STOP THE CLEANING PROCESS – continue to step “e”). Otherwise, allow the blades to remain immersed in the solution until the foaming has stopped. However, do not leave acid in the iChlor for more than thirty (30) minutes. Excessive acid washing will damage the blades.

• Remove the iChlor from the bucket and place it in an empty five (5) gallon bucket. Rinse the inside and outside of the iChlor thoroughly with clean tap water and inspect. If deposits are still visible, repeat the acid-cleaning process.
  Cleaning the Cell Blades (Continued)

• Rinse the iChlor again with clean tap water and inspect. Once clean, replace the iChlor and resume normal operation.

• If the acid wash procedure is necessary, it is recommended that a sample of pool water be analyzed by a pool professional for excessive calcium hardness (i.e. ideal range is 200 to 400 ppm) and/or improper water balance.

• Inspect the inside of the iChlor every two (2) months (or more frequently in hard water areas). If no scale or debris deposits are observed inside the iChlor after four (4) months, it is not necessary to continue inspections every two (2) months. However, due to possible changes in pool water chemistry and filtering effectiveness, it is recommended that the cell be removed for inspection at least twice a year.

• Reconnect the iChlor SCG to the Power Center, then turn on AC power to the iChlor Power Center.

Winterizing
Very little chlorine production is needed in cold water so long as free chlorine levels are maintained at 2.0 – 4.0 ppm. The iChlor will not produce chlorine below 52° F ±3° F (11° C, ±1.67° C). This low-temperature cutoff extends the life of the cell. If preventative measures are not taken, freezing water may cause severe damage to the cell. Prevent freeze damage to the cell by running the pool pump continuously or winterize the pool by draining water from the pump, filter, and all intake and return lines. Remove the cell, clean and store it.

TROUBLESHOOTING

Use the following troubleshooting information to resolve possible problems with the iChlor® SCG.

WARNING
Switch OFF the main system power to the iChlor SCG cell before servicing.

Note: Switch the power off to the unit before attempting service or repair. Always remove AC power to the Power Center when plugging or unplugging the iChlor SCG cell into the Power Center.

TECHNICAL DATA

System Specifications – 110 VAC and 230 VAC Wiring

• Circuit Protection: Two-pole 20 AMP device at the electrical panel
• Input: 95-130 VAC, 50/60 Hz, 220 Watts (2 AMP) or 220-240 VAC, 50/60 Hz, 220 Watts (1 AMP)
• Output: 22-39 VDC @ 7.5 AMPS maximum from the Power Center

Note: A TIME CLOCK must be used if the iChlor SCG is used in “stand- alone” mode without an automation control system. When using the iChlor SCG and an IntelliFlo pump (or 2-speed pump) with an IntelliTouch®, EasyTouch® or SunTouch® Control System, the iChlor SCG AC power centre wires must be connected to the LOAD SIDE OF THE MAIN FILTER PUMP RELAY located in the load/power centre (see page 22 for diagram). This ensures that the iChlor SCG cell produces chlorine only when the main filter pump is on. This method does not require a ground fault circuit interrupter (GFCI) to protect the circuit.

IMPORTANT: When using iChlor SCG with an IntelliTouch Control System, it is recommended to wire the Power Center to the pump side of the relay located in the IntelliTouch Control System Load Center. This method does not require a ground fault circuit interrupter (GFCI) to protect the circuit.
