IMPORTANT WARNING AND SAFETY INSTRUCTIONS
WARNING CHEMICAL BURN HAZARD: Make sure all pumps are switched off at the main circuit breakers at the house before drilling into any pipes. Securely fasten all electrical, water and chemical lines. Locate chemical feed pumps and chemical storage tanks in a safe and secure area.
Strictly follow the acid manufacturers safety and handling protocols including hand, body and eye protection when transferring or handling acid. Safety precautions should be used when handling Muriatic acid to control pH water levels. Muriatic acid can cause serious body injury and damage pool equipment. Extra care must be taken when installing, maintaining and operating acid pump feed systems. Acid is dangerous to handle and should be properly contained, transported, poured, stored, and dispensed.
· Check the pH and sanitizer levels of the water before use. · Periodically use an independent pH and Chlorine test kit to verify that pH
and chlorine is at a safe level. If the pH and Oxidation Reduction Potential (ORP) or Flow Cell sensors are broken, depleted or dirty with oils, lotions, or other contaminants, they can report inaccurate results to the system causing incorrect water chemistry, which could harm people or equipment. · Check the IntelliChem® Controller main status display each day to ensure there are no Alarm messages. See “Troubleshooting” on page 45 for more information.
When using IntelliChem with 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 12 hours (referred to as pool water turnover). However, many factors have an effect on actual pump and filter system run times. Pool size, source of water, direct sun light, indoor/outdoor, screened and 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 an initial run time (starting point) for the pool pump and chlorinating system. Try initially setting the pool pump timer to 12 hours. It will take a few days to get just the right amount pool pump operating time. When the Chlorinator is wired with a pool pump timer (see page 6) results will vary greatly from one pool installation to the next, so this should be discussed with either the pool builder or your pool professional.
Using CO2 for pH Control
Plaster pools and pools using salt-chlorine generators typically cause a slow pH rise which must be managed. With the IntelliChem® controller muriatic acid or carbon dioxide (CO2) is dispensed into the filter system’s return water as needed until the Flow Cell pH sensor detects the proper pH level. Using CO2 for pH control eliminates the need to handle and stored acid and can be a safer method. As CO2 gas is injected into the pool water, it dissolves and creates carbonic acid. This weak acid is very efficient at lowering pH with the added benefit of self-limiting if the CO2 is over-fed.

Overview
The INTELLILCHEM® Water Chemistry Controller is a pH and ORP sensing device that dispenses correct amount of chlorine or bromine, muriatic acid or CO2 gas. The IntelliChem controller provides continual analysis of your swimming pool water sanitation and pH levels, providing real-time status information to dispense the proper amount of muriatic acid (pH reducer) and chlorine or bromine for the correct sanitization and pH balance. The IntelliChem controller operates with or without a salt chlorine generator to provide a self-replenishing supply of chlorine generated from salt. The IntelliChem controller can also connect to carbon dioxide (CO2) liquid gas tanks to lower pH in your swimming pool water. When CO2 dissolves into water it produces weak neutral bicarbonate salts which reduces pH. CO2 is environmentally friendly and produces no secondary pollution into the treated water by salts such as chlorides or sulfates. CO2 does not corrode metal equipment and does not require any special piping. The IntelliChem controller supports Pentair Aquatic Systems (“Pentair”), EasyTouch®, IntelliTouch® and SunTouch® automation control systems for pH and ORP control. The IntelliChem controller also supports IntelliChlor® salt chlorine generator (SCG) to help manage your pool water sanitizer levels. Operating the IntelliChem Controller Before operating the IntelliChem controller, it’s important to test and adjust your pool water chemistry to the recommended pool industry levels found in this manual (see page 19). If you are using an IntelliChlor salt chlorine generator, adjust the salt levels to the recommended levels in the IntelliChlor (SCG) Installation and User’s Guide (P/N 520589). During normal operation, no user input is required, the IntelliChem controller will automatically sense ORP and pH levels. The current ORP and pH levels are regularly displayed on the control panel LCD display. Use the pH Settings or ORP Settings buttons to view or adjust supply levels. The “Auto Setup” feature provides screen prompts for first-time setup or standard configurations such as setup reminder times, calculating feed times, proportional limits and alarms. For details, see page 6. First Balance Your Pool Water IMPORTANT: To help keep your pool water balanced follow these steps:
1. Use a Test Kit (with fresh testing reagents) to measure the pH, alkalinity, and calcium hardness of the pool water. For greater accuracy, Pentair recommends the AcuCheck3 Test Kit to measure pH, chlorine ppm, and alkalinity levels (P/N 745000110). “Balanced” water has proper levels of pH, Total Alkalinity and Calcium Hardness. This “balanced” water is neither corrosive or scaling. The pH (0-14) value is the scale of relative acidity or alkalinity. Recommended pH range is from 7.2 to 7.6. The IntelliChem controller default pH value is 7.5 (see page 12).
2. Be sure the pool chlorine level is balanced. Ideal free chlorine level should be between 1.0 – 3.0 parts per million (ppm).
3. Use the online Langelier Saturation Index (LSI) calculator to diagnose the water balance in your pool or the IntelliChem controller built-in LSI calculator (see page 28-31). Refer to: http://www.pentairpool.com/pool- owner/resources/calculators/langelier/
Note: A Saturation Index value of 0 indicates the water is chemically in balance. If the Index is a minus (-) value, corrosive tendencies are indicated. If the Index is a plus (+) value, scale-forming tendencies are indicated. A Saturation Index value between +0.5 to -0.5 is considered satisfactory in a swimming pool. See Saturation Index menu on page 28.

pH Menu (Continued) pH Sensitivity

The IntelliChem® Controller can adjust the feed times for pH depending on how close the current reading is to the set point. This helps to prevent overshooting and makes it easier for the IntelliChem controller to reach the exact set point. Note: Low = (default) Full dose at 0.5 pH above setpoint. High = Full dose at 0.2 pH above setpoint. Off = Full dose at 0.005 pH above setpoint For example: When set to LOW (full dose at 0.5 above setpoint), if pH setpoint is 7.2 and pH reading is 7.7 or above, a full dose amount is dispensed. As the pH comes closer to setpoint, say 7.45 (0.25 above setpoint – or- half the 0.5 pH value), the dispensed amount will be 1/2 of the specified dosage. And, at 0.05 (1/10th of 0.5 value) above setpoint (7.25), the dosage will be 10% of that specified in the dosage menu. In that case, if the dosage was specified to be 10 ounces, IntelliChem controller will dispense only 1 ounce at a time. This can be confusing because the display appears to not be dosing the full amount; therefore, in the Advanced display mode, the process timer shows “%Dosing 0.1 oz”, the “%” indicates the dosage is reduced due to this Sensitivity feature. In SPA Mode, the leading “s” in “sDosing 0.1 oz” indicates the dose is further reduced by 25%.
To set the pH Sensitivity level: Press MENU – pH Menu / pH Sensitivity

Monitoring pH OK 7.25 %Dosing 0.1 oz

“Dosing” is preceded with a “%” to indicate the dosage is being reduced through the Sensitivity feature.

Spa Mode is activated when the IntelliChem Controller detects that the control system has turned on the Spa. The SPA indicator should be illuminated on the automation control panel. Switching from a large body of water like a pool to a typically a smaller spa automatically reduces the dispensed dosage to 25% of a normal dose. The IntelliChem’s Advanced display precedes the Dosing message with a “s” to indicate it is in this mode. This feature is only available if the IntelliChem Contrroller is connected to a Pentair control system.

pH Alarms

The IntelliChem controller automatically displays a screen message indicating the pH level has reached or exceeded the HIGH (7.8) or LOW (6.8) pH alarm level settings. The IntelliChem controller will automatically set a high and low alarm for the pH level. The Delay time is the amount of time between the detected alarm condition and when the IntelliChem controller displays the alarm message on the main screen. The Delay setting is adjusted in increments of 15 seconds.
To set the pH alarm “High” level and “Delay” time (page 1/2): Press MENU pH Menu pH Alarms / pH Alarms / (page 1/2 is High Level Alarm, page 2/2 is Low Level Alarm) Press to select the alarm, High level and Delay Time (00:50:00).

ORP Menu Description (Continued)

ORP Sensitivity

IntelliChem® Controller can adjust the feed times for ORP depending on how close the current reading is to the set point. This helps to prevent overshooting and makes it easier for IntelliChem controller to reach the exact set point. Note: Low= (default) Full dose at 50mV below setpoint. High= Full dose at 20mV below setpoint Off= Full dose at 1mV below setpoint
For example: When set to LOW (full dose at 50mV below setpoint), if ORP setpoint is 700 and ORP reading is 650 or below, a full dose amount is dispensed. As the ORP comes closer to setpoint, say 675mV (25mV below setpoint – or- half the 50mV value), the dispensed amount will be 1/2 of the specified dosage. And, at 695 (1/10th of 50mV value) below setpoint (700), the dosage will be 10% of that specified in the dosage menu. In that case, if the dosage was specified to be 10 ounces, the IntelliChem controller will dispense only 1 ounce at a time. This can be confusing because the display appears to not be dosing the full amount; therefore, in the Advanced display mode, the process timer shows “%Dosing 0.1 oz”, the “%” indicates the dosage is reduced due to this Sensitivity feature.In SPA Mode, the leading “s” in “sDosing 0.1 oz” indicates the dose is further reduced by 25%.

Dose Priority: pH Priority or Simultaneous. Depending on how the IntelliChem chemical dosers are plumbed and how much water is circulating in the system where the chemicals are injected into the water stream, it may be preferred to only feed Chlorine when Acid is not feeding. This would be the pH Priority setting.

· Simultaneous allows both chemicals to feed at the same time – and
can be used when both feed systems are not liquid chemicals or the injectors are separated by a safe distance in the water stream. DANGER: Combining liquid acid and chlorine can result in the formation of hazardous and explosive gas.
· pH Priority will always feed acid first, and only during the acid mix time
or general monitoring period will the IntelliChem feed the liquid chlorine sanitizer. If while feeding chlorine, the pH rises above setpoint, the ORP
dose will be stopped and allow acid to feed.

Chlorinator: This screen displays the current IntelliChlor (SCG) status, salt (ppm) levels and error conditions. The hexadecimal status value is decoded and displayed in the brackets on the bottom line; multiple error conditions are shown by sequencing through the messages. This display can be used to determine if the SCG is connected and responding to the IntelliChem. If the IntelliChlor is connected, this display may show “Please wait 2-7 minutes for ppm”. This indicates the IntelliChlor is responding to initial contact but until water flow and sufficient salt level is reached, the IntelliChlor will not respond with further information like salt ppm and status. Sometimes it is helpful to cycle power on the IntelliChlor and wait 10 minutes for the green lights before it will respond with ppm and status information; it may not respond if the Salt or Cell lights are flashing red. If the Configuration / Hardware / ORP Control / Doser Type is set to IntelliChlor, the IntelliChem will control the IntelliChlor as it would a doser, actively turning it on (100%) for chlorine demand, and off (0%) when the ORP reaches the desired set point. For the Chlorinator to work when connected to an Automation controller like the IntelliTouch, EasyTouch, or SunTouch, those units must be configured with the IntelliChlor enabled.

SAT Index Overview

Saturation Index
The Saturation Index (SI), also called the Langelier Index, is a chemical equation or formula used to diagnose the water balance in the pool. The Saturation Index formula is SI = pH + TF + CF + AF – 12.1 (or 12.2 for salt pools). To calculate the Saturation Index, you must first test the pool water for pH, temperature, calcium hardness, and total alkalinity. Refer to a chart for assigned values for your temperature, hardness, and alkalinity readings then add these to your pH value. Subtract 12.1 (or 12.2 for salt pools), which is the constant value assigned to Total Dissolved Solids and a resultant number will be produced. A result between +/-0.3 indicates balanced water. Test results not within these values require chemical adjustments to achieve balance. This formula is more or less reliable but not guaranteed. In some cases, individual readings for pH, calcium, and Total-Alkalinity might be beyond normal recommendations, however, combined within the formula can produce “balanced water.” The SI is useful to pinpoint potential water balance problems.

To access the Sat Index menu: Press MENU / Saturatn Index Press / and /to adjust the Saturation Index values.

Recommended Pool Chemistry

pH range:

7.2 to 7.6

ORP range:

650 to 750

Alkanlinity:

80 to 120 ppm

Calcium Hardness:

200 – 500 ppm

Cyanuric Acid/Stablizer:

Less than 30 ppm

pH: Chlorine produced by the IntelliChlor SCG is close to Neutral pH. However, other factors usually cause the pH of the pool water to rise. Therefore, the pH in a pool chlorinated by IntelliChlor tends to stabilize at approximately 7.8. This is within APSP standards. If the pool pH rises above 7.8, 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.
Temperature: The pool water temperature can affect the saturation index value. IntelliChem gets the temperature from the EasyTouch, IntelliTouch and SunTouch automation control system. The automation control system must have the POOL or SPA pump running to report the proper temperature to IntelliChem, otherwise IntelliChem will use its own menu’s temperature value. To change the IntelliChem default temperature, select Temp and use the Up/Down arrow to adjust the temperature.

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 7.2 to 7.6. 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 by-products can damage the IntelliChlor SCG

Calcium Hardness Recommended range for calcium hardness is 200-500 ppm. Calcium Hardness levels should be tested weekly. Calcium hardness is the calcium carbonate scale deposited on pool surfaces. The test for Calcium Hardness is a measure of how “hard” or “soft” the water is testing. “Hard” water can have high levels of calcium and magnesium. If these levels are too high the water becomes saturated and will leave calcium carbonate scale deposits (a “white-ish,” crystallized rough spot) on any surface inside the pool. If the levels are too low, the water becomes “soft” and will corrode surfaces inside the pool. Use TSP or Hydroquest 100 to lower Calcium Hardness levels that are too high or add water to the pool which has a lower calcium hardness content. Levels which are too low require the addition of calcium chloride.

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 IntelliChlor system. The individual performing the TDS test may then subtract the salinity level to arrive at a TDS level that would be compatible to a TDS reading for a non-salt water pool.
Note: If a salt chlorine generator is being used for your pool, the salt level is the TDS level of the pool.

INTELLICHEM® Controller Installation and User’s Guide

27
Sat Index Overview (Continued)
Total Alkalinity APSP’s recommended ideal range for total alkalinity is 80 to 120 ppm for “gunite” and concrete pools and 125-170 ppm for painted, vinyl, and fiberglass pools. Test levels weekly and adjust according to your pool professional’s recommendations. Total Alkalinity can be described as a buffer that keeps pH in order. pH depends on the ability of the total alkalinity in the water to withstand the changes in pH. If the total alkalinity is too high, adding acid (similar to pH) lowers the level. Adding a base (e.g sodium bicarbonate) when total alkalinity is low, raises the level. The level of total alkalinity in the water is a measurement of all carbonates, bicarbonates, hydroxides, and other alkaline substances found in the pool water.
Cyanuric Acid: Cyanuric acid is needed in outdoor pools to help to stabilize and maintain proper levels of chlorine. 90% of unstabilized chlorine is destroyed by the UV radiation from the sun. Cyanuric acid stabilizes chlorine in water from UV degradation. When using the IntelliChlor SCG, the cyanuric acid level should be maintained at less than 30 ppm.
Optimum Pool Water Chemistry Conditions for Salt Water Pools (using the IntelliChlor® Salt Chlorine Generator (SCG)
In accordance with the Association of Pool and Spa Professionals (APSP) standards, it is recommended that the pool water chemistry conditions (see page 21) be maintained on an on going 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, liming or other problems. The IntelliChlor (SCG) is warranted to operate properly only if these conditions are met. 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). Recommended pool water chemistry is given below: Free Chlorine: 2.0 – 4.0 ppm. Above 4.0 ppm may cause corrosion of metal components Combined Chlorine (Chloramines): None (super chlorinate to remove all chloramines) pH: 7.2 – 7.8 (USE MURIATIC ACID to lower pH and Soda Ash to raise pH.) Cyanuric Acid: Less than 30 ppm Total Alkalinity: 80 – 120 ppm Calcium Hardness: 200 – 400 ppm TDS (includes salt): 3000 minium to 5700 to 6000 maximum ppm Salt: 3000 – 4500 ppm (ideal 3400 ppm) Metals (Copper, Iron, Manganese): None Nitrates: None – Phosphates: Less than 125 ppb
Using the Langelier Saturation Index (LSI) to Diagnose Water Balance
Use the Langelier Saturation Index (LSI) calculator to diagnose the water balance in your pool. Water with a LSI of 1.0 is one unit above a balanced condition. Reducing the factors by 1 unit will bring the water into equilibrium. To use the LSI calculator, refer to:

Calculating the Saturation Index
The saturation index is a formula that relates pH, calcium and alkalinity in the pool water. A well balanced pool water will have a formula result range between -0.5 and 0.5 Outside this range, the pool water is out of balance, potentially damaging pool equipment or scaling the salt chlorine generator. The equation to calculate Si is:

SI = pH + CHF + AF + TF – TDSF

Cyanuric acid in the form of cyanurate ions contribute 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 240 ppm cyanuric acid, the correction amounts to 80 ppm (240 ÷ 3 = 80).

Before installing the IntelliChem controller, read the following instructions.

1. IMPORTANT! If the equipment pad is below the water level of the pool, please install a CHECK VALVE after the heater or use a Hartford Loop. 2. Identify new and existing equipment to be connected. 3. Decide if the sensors will be in a separate bypass line, or if the Flow cell will be used. Caution: If the Flow Cell is being installed, the input water maximum pressure is 25 PSI. 4. Determine the supply voltage, and wire the transformer wires as needed (see page 31). 5. Determine if the control to the equipment uses the same voltage as the supply voltage. All controlled equipment must be compatible. 6. Determine the water-tap points for the flow cell bypass inlet and outlet. 7. Install the Flow Cell away from direct sunlight and on a flat vertical surface. 8. Switch the main house circuit breaker OFF. Connect the supply voltage to the PUMP SIDE OF THE MAIN FILTER PUMP RELAY located in the load/ power center (see page 40 for the IntelliChem controller AC power wiring diagram). This ensures that the IntelliChem controller will only dispense chemicals when the filter pump is ON. Note: The IntelliChem controller must be connected to a separate dedicated circuit GFCI. 9. If using a Flow Cell install the bypass now. 10. Connect the pH and ORP sensors. 11. Test the plumbing for leaks. 12. Switch on the IntelliChem controller for the first time as described below.
   Risk of Electrical Shock or Electrocution! IntelliChem controller must be installed by a licensed or certified electrician or a qualified pool professional in accordance with the current National Electrical Code and all applicable local codes and ordinances.

Plumbing the Flow Cell

Be sure to have a licensed plumber perform all plumbing; this is important, as they will be familiar with all of the codes in the local area.
To connect the Flow Cell to the system plumbing: See page 37 for plumbing diagram.
1. At the equipment pad, switch off the filter pump and release the pressure from the system by opening the valve on top of the filter.
WARNING CHEMICAL BURN HAZARD: Make sure all pumps are switched off at the main circuit breakers at the house before drilling into any pipes. Securely fasten all electrical, water and chemical lines. Locate chemical feed pumps and chemical storage tanks in a safe and secure area.
2. Close all valves to prevent flooding. 3. Attach the IN and OUT tubes to the Flow Cell Inlet and Outlet
(see Tubing Installation Diagram shown below). 4. Run the end of the IN tube to the chosen pressure line. Choose a location
that provides enough space to drill and to tighten the clamp (must be after the filter, but before the heater). Be sure the tube is not pinched or kinked. Mark a spot on the pipe. 5. Locate where the water will be supplied from and returned for each flow cell. The most common location for the water inlet to the flow cell is AFTER the main filter and BEFORE the heater. See page 37. 6. Drill a 3/8″ hole for the flexible tubing fitting on the mark and immediately place the fitting into the pipe. Align pipe clamp with the fitting and tighten the pipe clamp. 7. Run the end of the OUT tube (with the pipe clamp) to the chosen return line. Choose a location that provides enough space to drill and to tighten the clamp (must be after the heater – see page 37). Be sure the tube is not pinched or kinked. Mark a spot on the return line pipe. 8. Drill a 3/8″ hole for the flexible tubing fitting on the mark and immediately place the fitting into the pipe. Align pipe clamp with the fitting and tighten the pipe clamp. 9. Open any closed system valves. Close the filter valve and turn on the circulation system. Check that the system is working properly.

Check for leaks and verify the flow sensor indicates flow.
Flow Cell Inlet and Exit Lines 1. It is essential that the supply line be at a higher pressure than the discharge line so the water will flow through the cell at a steady rate in the right direction. 2. Inlet should be installed after filter and before heater. Note: Plumb the INLET before the solar valve. 3. Exit should be installed after heater and as far away from any equipment as possible. Make sure all pumps are OFF before drilling into pipes. Never switch ON chemical feed pumps without the pool filter pump also running. The flow switch is a dry contact only (no current). Use with any other brand of flow switch voids WARRANTY and UL listing.

TROUBLESHOOTING

General Troubleshooting Guide (also see Help Guide on page 47) 1. Run Meter Self-Test (see Configuration menu)
2. Run Probe-Open Test (see Configuration menu) 3. Clear pH and ORP Tweaks (see Configuration menu) 4. Clean Sensors (see Maintenance section) 5. Check chemicals and feed system 6. Take sample of pool water for analysis of CYA, alkalinity, check saturation
index, Balance water 7. Replace Sensors 8. Repeat above steps
General Guidelines – pH or ORP not able to reach setpoint
This may be a common issue that can easily be resolved by increasing the amount of chemical dispensed each day. If the pH Sensitivity is set to “Low” (the default), IntelliChem will only administer the full dose at 0.5 from setpoint. If it seems to be stuck 0.3 from setpoint, you’re only getting 3/5 of the programmed dose. Change the Sensitivity to “High” and you’ll get the full dose at 0.2 pH or greater from setpoint. Or, turn pH Sensitivity OFF only turn it on if you’re overshooting the setpoint. Increasing the dose would essentially do the same thing. Increase the dosage as well as the dose-limit and reduce the mix time so you still get all 8 doses in the filter run time.
Diagnostics Self Test and Error codes
The overall functionality of the IntelliChem can be verified by running the self test. Access this feature in the Configuration/Diagnostic menu. The test verify the LCD display, front panel LED indicators, push buttons, flow switch input, doser motors, relays, the RS-485 communication, and the meter. Warning! This test will turn on the doser, so be sure that the tubing is installed in a safe manner so that the chemicals will be safely contained.

Refill the chemical supply container and set the gauge to the appropriate corresponding level. This alarm indicates level is low and should be refilled. If non-fluid supply sources are used, like CO2 and SCG, you can set a reminder in the pH/ORP Supplies 2/2 menu that will trigger this alarm as a reminder to change CO2 canisters or clean the SCG plates. The reminder is reset either in the Supplies 2/2 menu or the pH/ORP Settings button.
Increase filter time and increase dose size. This may be the result of the ORP Sensitivity setting. If the sensitivity is set to “Low”, you may not have a sufficiently sized dose to reach the setpoint. Try turning Sensitivity to “High” or “Off”.
Check overall water chemistry using the Saturation Index calculator or have water tested by a professional pool service person or dealer. Also, check that the dose dispensing device is operating properly and that your supply tank is full.
Overshooting ORP may simply be a result of Cyanuric acid in the pool which suppresses the ORP during the sunlight hours and releases chlorine at night. It may also be that dose size is set too high with insufficient mix time. Turning ORP Sensitivity to “Low” may help reduce overshooting.
Overshooting pH may be due to the dose size being set too high with insufficient mix time. Turning pH S ensitivity to “Low” may help reduce overshooting. Test overall water chemistry using the Saturation Index calculator. Low Total Alkalinity may contribute to rapid pH swings and make controlling water nearly impossible. Consult your pool professional. Check overall water chemistry using the Saturation Index calculator or have water tested by a professional pool service person or dealer. Also, check that the dose dispensing device is operating properly and that your supply tank is full.
Increase filter time and increase dose size. This may be the result of the pH Sensitivity setting. If the sensitivity is set to “Low”, you may not have a sufficiently sized dose to reach the setpoint. Try turning Sensitivity to “High” or “Off”.

NO FLOW DETECTED

No Flow

Check pump, flow cell, filter, and valves.

Ensure the pool pump is turned on, that valves are properly positioned, and that sufficient water is being directed to the flow cell. Make sure the flow switch is closed (shorted) which indicates flow.
Warning: This is a Safety Device. Do not operate the IntelliChem with the flow switch bypassed. Water flow must be present to ensure chemicals are mixed adequately to avoid dangerous gasses and high concentrations of chemicals near people or pool equipment.

Awaiting FLOW DELAY

Flow Delay

pH has priority

PH Priority

This is not an alarm, only a message indicating that water chemistry control will commence after this count-down timer expires. To allow pool water to stabilize and time for chemicals to activate, a minimum of 15 minutes is required to get accurate readings. The Flow Delay is set in the Configuration/Delays menu. It is the combination of the Power- On and Flow- Switch delay settings. As a convenience for the pool service person, you may bypass the delay by holding the Up Arrow button for 3 seconds. Please give time for the water to stabilize before expecting proper operation of the equipment.
This is not an alarm but a message that pH is feeding (acid) and that ORP (chlorine) is on hold until the acid feed is finished. This is enabled in the Configuration/Dose Priority menu on systems where the acid and chlorine may be injecting near the same point in the plumbing and the installer has decided, for safety reasons, to only feed one chemical at a time.

Tweaking pH (Calibrating Sensor)
Measure the pH using a standard test kit by taking several readings and averaging the results. To Tweak the pH sensor see page 12.
Tweaking ORP (Calibrating Sensor)
Always make sure the pH is at the set point before calibrating ORP. Always control at PPM levels greater than 1.0 PPM when using ORP sensors.
IMPORTANT: For best results the ORP should be at the ORP set point when calibrating. For best results the PPM should be at the desired level when calibrating ORP. To Tweak the ORP sensor see page 15.

MAINTENANCE
Winterizing: The Flow Cell sensors must be protected from freezing conditions. If the pool is winterized, plan to remove and store the sensors (as described above) as part of the normal pool winterizing process. The Flow Cell and related plumbing must be drained as well.
Water Chemistry Always test water chemistry with a quality manual test kit. Therefore, it may be preferable to calibrate pH using commercially available reference solutions. If required, use the IntelliChem Tweak pH feature to periodically adjust the pH reading (see above and page 12). It’s important to note that changes in pH, cyanuric acid concentration, total dissolved solids, and use of additional or alternative sanitizers will all affect the primary sanitizer residual level relative to ORP. Maintain total alkalinity on regular basis to ensure pH stability. To maintain a consistent sanitizer residual in parts per million (ppm), periodically adjust the ORP level.
Sensor Maintenance: The Flow Cell sensors must be clean and free from oil, chemical deposits and contamination to function properly. After saturation in pool or spa water, the sensors may need to be cleaned on a weekly or monthly basis depending on bather load and other pool specific characteristics. Slow response, increased need to calibrate pH, and inconsistent readings are indications that the probes are in need of cleaning.

INTELLICHEM® Controller Installation and User’s Guide

52
MAINTENANCE (Continued)
Cleaning the Flow Cell Sensors: To clean the ORP and pH sensors, turn off the AC source power to IntelliChem at the GFCI switch. Disconnect the probe connectors from the Flow Cell, unscrew the probe and carefully remove them from the Flow Cell. Clean the reference junction (the white ring at the bottom of the probe body) with a soft toothbrush. A household liquid dish washing detergent may also be used to remove any oil. Rinse with fresh water and reinstall probes. If properly cleaned probes continue to provide unstable readings or require excessive calibration, the probes should be replaced. Probe exposed to atmospheric conditions will cause the probe tips to dry out. Store the sensors with the included plastic sensors storage caps if removed from the Flow Cell for more than one hour. If the storage caps have been misplaced, store the probes individually in small glass or plastic containers with clean water covering the sensor tips. Store sensors in a location that will not be subjected to freezing temperatures.
Sensor Care
Contamination of the sensing elements often results in slow response and inaccurate readings. Clean the elements by the following procedures: pH and ORP Sensors
1. Wash electrode tip in a liquid detergent and water. Carefully use a soft bristled toothbrush to wash the electrode tip and white sensing ring.
2. Rinse after cleaning. To reinstall the flow cell (see page 33). Hand tighten to sensors to secure in place.
3. Make sure the O-ring is installed on sensor. 4. If the cable is longer than needed, it should be coiled neatly and attached
under the enclosure. pH Sensors Only
5. Attempt to clean the sensor with liquid detergent first. 6. If this is not successful, swirl the tip of the sensor in a 5 parts water and 1
part muriatic acid solution for 10 – 20 seconds. 7. Rinse again and reinstall.
WARNING Do not rub hard the glass element in the sensor or use sand paper or other polishing material to clean. HANDLE ELECTRODE CAREFULLY Sensors contain external and internal glass elements. Do not drop or otherwise subject the sensor to vibration, physical impact, or freezing conditions. ANY TYPE OF BREAKAGE IS NOT COVERED UNDER WARRANTY.
pH and ORP Sensors: pH electrodes sense the acidity of the water and work with any acid or base. The blue bands on the cables identify the pH sensors. The red bands on the cables identify ORP sensors. Each sensor is also identified on the sensor body. ORP electrodes are used to monitor the Oxidation Reduction Potential (ORP is sanitization quality of the water) of a given solution. The sensing element of the ORP electrode is made of a precious metal such as platinum or gold. Sensors: IntelliChem measures the following sensor measurements with the listed characteristics:
pH Range: 4.00 to 9.99 ORP Range: 0 to 999 mV Flow Switch: This input measures if a switch is open or closed. Open is no water flow. A closed switch indicates flow.

Appendix A: 2016 IntelliChem Controller Configurations
Starting in 2016, there are now three IntelliChem Controller system configurations that are intended to make the initial setup easier:
1. P/N 521357 ­ Includes just the controller, flow cell, and probes. This system is NSF approved.
2. P/N 522621 ­ Includes the controller, flow cell, probes, and a 4 gallon acid tank with a new Stenner 50 GPD pump mounted to it. The pump has a 15 foot cable that plugs into a new dedicated spot on the IntelliChem motherboard for easy setup.
3. P/N 522622 ­ Includes the controller, flow cell, probes, and 4 gallon acid and chlorine tanks with new Stenner 50 GPD pump mounted to them.
Older IntelliChem Controller systems can be upgraded to this new style with the following part numbers:
· P/N 522474 ­ Upgrades older non-pump containers (521378 & 521397) with the new tank mounted Stenner pump.
· P/N 522478Z ­ Upgrades older IntelliChem Controller motherboards to allow use with new acid and chlorine tanks with tank mounted pump.
· P/N 522472 ­ Acid tank with tank mounted pump.
· P/N 522473 ­ Chlorine tank with tank mounted pump.
Please note that Pentair always recommends 1:1 dilution when using full strength muriatic acid. When mixing, remember to always add acid to water.

The new Stenner pump uses the same programming as the 50 GPD wall mounted Stenner pump that was shipped with IntelliChem from 2012 to 2014. The 50 GPD tube in the new Stenner pump has a higher burst pressure rating (80psi) than the discontinued #5 Stenner tube (25psi).

Installing the IntelliChem Tank with Pump (P/N 522472 & 522473)
1. Find a suitable location to secure the tank to the equipment pad. The tank needs to be within 10′ of the IntelliChem Controller, 10′ of the return plumbing, and away from equipment that may be damaged by the chemical or vapor.
2. Secure the tank to the equipment pad with four bolts. 3. Cut off 1-2′ of tubing and connect the black suction fitting of the tank to the
inlet (right) of the pump. See Figure 1. Do not overtighten the nuts. 4. Install the injection fitting in the return plumbing, after all equipment. 5. Use the remaining tubing to connect the outlet (left) of the pump to the
injection fitting. Note: Do not overtighten the nuts.
Upgrading a Chemical Container with Pump Kit, Using P/N 522474
1. Be sure the Chemical Container is secured to the equipment pad, and in a suitable location within 10′ of the IntelliChem Controller.
2. Remove the four screws and block-off plate. 3. Install the motor shroud with four screws. See Figure 1. 4. Mount the pump on the motor shroud with four screws. See Figure 1. 5. Cut off 1-2′ of tubing and connect the black suction fitting of the tank to the
inlet (right) of the pump. See Figure 1. Note: Do not overtighten the nuts. 6. Install the injection fitting in the return plumbing, after all equipment. 7. Use the remaining tubing to connect the outlet (left) of the pump to the
injection fitting. Note: Do not overtighten the nuts.
