SAFETY INSTRUCTIONS

IMPORTANT SAFETY INSTRUCTIONS. Read and follow all instructions. Ensure all owners/operators of this equipment have access to these instructions. Save all instructions. When installing and using this electrical equipment, basic safety precautions should always be followed, including the following.

• WARNING: Follow all aspects of local and National Electrical Code(s) when installing the CircuPool SJ Series. Disconnect all electrical power during installation & service.

• WARNING: To reduce the risk of injury, do not permit children to operate this device. Service should only be attempted by a qualified professional.

• WARNING : Heavy pool (and/or spa) usage and higher temperatures may require higher chlorine output to maintain proper free available chlorine residuals. The actual amount of chlorination required by your pool can change and varies according to factors not limited to bather load, rain, temperature, dirt, debris, and chemical balance.
  WARNING: Safe operation of the electrolytic Cell requires a minimum water flow rate of 20 gpm. Never operate the unit when the flow of water is restricted. Always turn the unit off when operating any plumbing control valves such as for backwashing, water exhaust, or during the operation of spa or water features. If the operation restricts water flow to the Cell, a build- up of flammable gases will result in hazardous conditions.

• WARNING: We strongly recommend against the use of isolation valves. If full pump pressure is applied to an isolated component, it may be prone to rupture. Turn off all pumps before changing valve positions. Prevent water pressure spikes at Electrolytic Cells.

• Before installation, ensure that materials and equipment used in and around the pool are compatible with the use of chlorinated water and salt. Avoid high chlorine and high salt levels (above the recommended range); it is possible that certain materials and pool (and/or spa) equipment may be susceptible to damage.

• Ensure that the chlorinator operates only when the circulation pump is operating. When installed with a pool equipment timer or control system, wire the Control Module (wall unit) to the load side of the timer clock or control relay.

• If additional chlorine is required (due to heavy bather loads, for example), use Sodium Hypochlorite to maintain an appropriate chlorine residual in the water.

• DO NOT add acid or other concentrated chemicals directly to the skimmer. This may damage the Cell.

• Check the expiration date of any test kits as test results may be inaccurate if used after that date.

• When replacing the Cell, only use replacement Cells having a label that clearly states that it is the replacement for this SJ Series model.

• Proper pool chemistry must be maintained at all times. For outdoor pools, chlorine residuals can be protected from destruction by sunlight with the addition of a stabilizer (cyanuric acid).

• The use of dry acid may damage the salt Cell and is not recommended. When using liquid acid, always add acid to water, never water to acid.

• For proper sanitation, spas must be completely drained periodically. The number of days between COMPLETE SPA DRAINAGE is equal to the volume of the spa water in gallons, divided by 10 times the maximum number of daily spa users. Refill the spa with water and repeat the initial startup instructions on pages 6-8 of this manual.

• Ensure that the SJ Series installation does not constitute a cross-connection with the local potable water supply.

• Consult local plumbing codes.

• Note: Some local codes may require an external grounding source. Check your local ordinances.

• To reduce the risk of electric shock, the ground wire (green wire) on the power cord must be connected to the grounding means provided in the electric supply service panel.

• One bonding lug for US models is provided on the external surface. To reduce the risk of electric shock, connect the local common bonding grid in the area of the swimming pool, spa, or hot tub to these terminals with an insulated or bare copper conductor not smaller than 8 AWG US.

SJ SERIES SYSTEM OVERVIEW
The CircuPool SJ-Series system comes with three main components:

Control Module
This component supplies power to the Cell and allows you to customize the system’s operation in order to meet your pool’s unique needs.

Electrolytic Cell
This component creates chlorine as the water inside passes through and returns to the pool. The Electrolytic Cell (“Cell”) contains a bipolar set of titanium plates that use a low level of DC electrical power to generate chlorine from salt in the water.

Cleaning Tool
This component is unique to the CircuPool SJ Series and allows for simple acid-free maintenance of the Cell. Additional Items Required For Installation (Not Included) PVC Cement, PVC Primer, Hacksaw or Pipe Cutters, Screwdrivers, Permanent Marker, 2x 90° Elbows, and a section of straight PVC Pipe (length depending on your equipment layout)

WATER CHEMISTRY & SALT LEVELS

Preparing the Pool Water
It is important that the pool’s water chemistry is balanced before the SJ- Series is powered on and used. In order for the system to be able to work, there must be a minimum level of salt in the pool water, see “Salt Levels” below. In order to achieve normal pool operation, water chemistry needs to be balanced according to the national standards listed under “Ideal Chemistry Levels” on page 8. DO NOT add chemicals or salt directly to the skimmer. This may damage the Cell. If the system has already been installed, it should not be turned on before adding salt. Additionally, leave the salt chlorinator off any time there is a chance of recently added chemicals going through the salt Cell in a concentrated form. For New Pools / Remodels: Wait 30 days or longer if specified by your builder for plaster to cure before adding salt. For Biguanide (Non-Chlorine) Pools: Ensure any Biguanide-based chemicals have been removed prior to startup.

Ideal Salt Levels & Pool Size
The CircuPool SJ-Series can work within a broad salinity range, from a minimum of 3500 ppm (parts per million), to upwards of 5000 ppm. However, the ideal level for operation is around 4000-4500 ppm. To achieve this level of salinity, use the chart on page 7, which will help you add approximately 35 lbs of salt for every 1000 gallons of water (or 4 Kilograms of salt for every 1000 Liters). If you are unsure of the number of gallons in your pool, double- check with the following equations.

Calculating Gallons (Dimensions in Feet)

Rectangular Pool

Pool Width x Pool Length x Average Depth x 7.5 = Pool Gallons

Round Pool

Pool Diameter x Pool Diameter x Average Depth x 5.9 = Pool Gallons

Oval Pool

Pool Width x Pool Length x Average Depth x 6.7 = Pool Gallons

Example – 15’ x 30’ Rectangular Pool with 3’ shallow end and 6’ deep end.

15 ’ wide x 30 ’ long x 4.5’ Average Depth x 7.5 = 15187 Gallons

IMPORTANT: Before adding salt at any time, ALWAYS perform an independent water test to measure pre-existing salt levels. After measuring for any existing salt content in the pool, add salt according to the chart above. The chart allows you to cross-reference your existing salt level and your pool size to estimate the number of pounds of salt required to achieve 4,000 ppm. Without the right amount of salt, the result will be reduced efficiency and a low level of chlorine production. In addition, operation at low salt levels will reduce the longevity of the Cell.

When adding the salt to the pool, it is best to empty the required salt into the shallow end of the pool and run the filter and pump simultaneously in order to circulate the water and dissolve the salt (the SJ-Series is to remain off during this time period). Do not throw the salt bag into the water as chemicals and inks on the bag can interfere with water balance. Salt may take 24 – 48 hours to dissolve in summer, and longer in winter. Finer granules of salt will dissolve faster than compressed pellets.

The salt in your pool is constantly recycled and does not normally need to be replenished frequently. The loss of salt throughout the swimming season should be small and is due primarily to the addition of extra water to replace water lost from splashing, backwashing, and draining. Salt is not lost due to evaporation. Use only evaporated, granulated, non-iodized salt (Sodium Chloride). The more pure the salt (at least 99%), the better the life and performance of the Electrolytic Cell. Water Softener salt (also known as Water Conditioning pellets) is an economical way to buy large quantities of salt. However, only salt that is at least 99% pure NaCl can be used. Pellets are compressed forms of evaporated salt that may take longer to dissolve. Avoid using salt with anti-caking agents (Sodium Ferrocyanide, also known as YPS or Yellow Prussiate of Soda) that could cause discoloration of fittings and surface finishes in the pool. Do not use Calcium Chloride as a source of salt. Do not use Rock Salt; insoluble impurities mixed with the rock salt can shorten the life of the unit.
TIP : When adding large quantities of salt, independently test the existing salt levels and add in portions, retesting at each stage.

Ideal Water Chemistry Levels

It is important to maintain these chemistry levels in order to ensure that the pool can be enjoyed safely, to minimize the amount of effort required to sanitize the water and to prevent corrosion or scaling. The only unique requirement for a pool with a chlorine generator is the low level of salt (salinity) to be maintained in the water. It may be helpful to provide this manual to any pool professional that you may have performing chemical testing or service, as requirements may vary from brand to brand.

Swimming Pools Spas
Free Available Chlorine 1.0 – 3.0 ppm 3.0 – 5.0 ppm Salinity 4000 – 4500 ppm 4000-4500 ppm pH 7.2 – 7.8 7.2 – 7.8 Total Alkalinity 80 – 120 ppm 80 – 120 ppm Calcium Hardness 200 – 400 ppm 150 – 450 ppm Stabilizer (Cyanuric Acid) 60 – 80 ppm 60 – 80 ppm Saturation Index (LSI) -0.2 to +0.2 (0 Best) -0.2 to +0.2

• Phosphates & Nitrates None (0 Best) None
• Metals None None
• TDS <1200 <1200

CHEMISTRY TIPS
Chlorine Stabilizer (Cyanuric Acid) Stabilizer is needed to maintain proper levels of chlorine; the sun’s UV radiation can destroy unstabilized chlorine as quickly as 2 hours. Stabilizers should be maintained between 60-80 ppm, as excessive amounts can also reduce chlorine effectiveness. Nitrates and Phosphates These chemicals are very common and can cause extremely high chlorine demands and can easily deplete your free chlorine levels to zero. Your local pool professional can test for Nitrates and Phosphates, levels should be at zero. Saturation Index (LSI) A calculated number used to predict the calcium carbonate stability of water. If the index is higher than +0.2, it can cause quick and excessive calcium scaling on the salt Cell. If the index is lower than -0.2, it can cause the water to be corrosive and damaging to metals and minerals in the water, such as the titanium inside the Cell. Metals Metals can cause the loss of chlorine. Also, metals can stain your pool and tint your water. Have your local professional test and recommend methods of removal. Be sure to use a phosphate-free metal remover.

Chloramines / Combined Chlorine Chloramines should not be present in pool water. When organic materials are not fully oxidized by Free Chlorine, Chloramines are formed. This ties up the Free Chlorine in your pool and does not allow the chlorine in your pool to disinfect. Chloramines also cloud pool water and burn the eyes. Superchlorinate (shock) to remove Chloramines at the initial startup of the pool.
pH Levels pH produced by the Electrolytic Cell is close to neutral pH. However, other factors usually cause the pH of the pool water to rise. Therefore the pH in a saltwater pool tends to stabilize at approximately 7.8. This is within national standards. pH levels above 7.8 drastically reduce the effectiveness of the chlorine, and can also contribute to excessive mineral scaling. If high, 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. 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 professional testing for TDS must be made aware that salt has been added. The individual performing the TDS test will then subtract the salinity level to arrive at the correct TDS level.

OPERATION

How it works
Think of the SJ-Series as a chlorine generator; set it to create a steady supply of chlorine for the pool, instead of buying and adding chlorine by hand.
How it works: Using electrolysis, it creates chlorine from the salt molecules (NaCL) in your water in order to sanitize your pool. A small electric charge is applied across a set of titanium plates inside the Electrolytic Cell. This produces Sodium Hypochlorite (NaOCl). In water, Sodium Hypochlorite dissociates into sodium (NA+) and hypochlorite (OCl-) ions. It is the hypochlorite ions that form with the hydrogen (H+) ions (from the water) to form hypochlorous acid (HOCl), which is the active agent that destroys bacteria and algae and oxidizes organic matter. This form of chlorine works quickly in the pipe, leaving only a mild residual in the pool. In addition, the Electrolytic Cell continuously “shocks” the incoming water- burning off any oils, organic matter, or other particles that need to be oxidized. Best of all, the process continuously recycles the salt: after cleaning the pool, the original molecules reform, and the whole process begins again. The salt doesn’t get used up!

Initial Start-Up
Before starting the system for the first time, verify that the pool water is chemically balanced (see page 8) and that all installation items are completed (see page 19) Apply power to the pool pump switch (or timer controls). This should activate the system, and the LED lights will flash for the first few moments as the system initializes. The Power () LED indicator will then remain solid, the Chlorine Output LED indicators will display the selected level, and one of the Polarity LED indicators will be lit. The Polarity lights will alternate every six hours of run time, which minimizes the amount of mineral buildup that may occur and prolongs the life of the Cell.

Once powered on, you’ll want to set its power level (Chlorine Output). To find the optimum Chlorine Output setting, start at a setting of 75% and adjust as needed over the initial start-up period. Measure your available chlorine in the pool after two to three days, and adjust the Chlorine Output level accordingly. If the available chlorine is too high, lower the Output level; if the available chlorine is too low, raise the Output level. It will take a few adjustments to find the ideal setting for your pool. Once set for the pool’s current needs, it should only take minor adjustments of the system’s power level and/or pump run times throughout the season.

General Operation
By familiarizing yourself with the operation of the SJ-Series, you can achieve the maximum performance for your pool. There are three main factors that you can control that directly impact the resulting free chlorine level in the pool:

1. The chosen percentage of Chlorine Output on the Control Module
2. Hours of pump run-time each day
3. Water chemistry balance
4. Including the amount of salt in the pool and chemicals that affect chlorine demand, such as chlorine stabilizers, phosphates, nitrates, and more. See “Ideal Chemistry Levels” on page 8 for more important information.

After making the initial adjustments to your chosen Chlorine Output level, additional adjustments are typically only necessary due to changing seasonal temperatures, or changes in pool use and bather load. Like any pool, ensure that your pump runs long enough for all the pool water to pass through the filter 1.5x to 2x a day (usually at least 8 hours). This amount of time is typically more than sufficient for chlorination of the pool, but if the pool has high chlorine demand, running the pool pump longer allows for more chlorination. Measure your water chemistry and chlorine level on a regular basis.
As you use the system throughout the season, make sure that you clean the Cell as frequently as needed (see page 12). Once the system detects that the Cell needs to be cleaned, it will display the Service () LED light, and then will not be able to create more chlorine until all mineral scaling has been removed from the Cell.

Using the Control Module

CONTROLS

1. Chlorine Output Level: The LED indicators display the current level of chlorine output (the rate of chlorine production). This is the system’s power setting that you will choose in order to customize operation for your pool’s needs
2. Power: The green power LED indicator is illuminated during normal operation. If this light is flashing, see pages 21-22.
3. Service: The amber service LED indicator is illuminated as a simple way to let you know when maintenance or service is required, see pages 21-22.
4. Polarity: These LED indicators (one green LED, one amber LED) will alternate automatically every 6 hours of operation as part of the system’s self-cleaning feature.
5. Chlorine Output Control: Press once to raise (+) or lower (-) your Chlorine Output Level. Raising the level past 100% will activate the Super CL boost mode (red LED light).
6. On/Off Switch: Press to activate or deactivate the main system power.
   SAFETY TIP: Always disconnect power at the circuit breaker prior to attempting any service procedure.

Using the Control Module (Continued)
The SJ-Series is designed to be unrivaled in its easy operation and minimal maintenance. Leave the Control Module switch in the “On” position, so that it activates when power is engaged by the pool pump timer or controls. When doing so, the Control Module returns to operation with its last settings. During normal operation, you can select the Chlorine Output Level by pressing the button (+) to increase or (-) to decrease output by one increment. Upon each adjustment, the LED on the Output Control button will illuminate, which indicates activation of the control system, followed by the corresponding change to the Chlorine Output Level LED’s.

As long as you maintain your pool’s salinity above the minimum level, and occasionally clean the cell when necessary, the system’s chlorine generation performance is assured! The system verifies that it is operating normally when its green Power LED indicator stays lit solidly, and if there is an issue, the yellow Service LED indicator will alert you if you need to add salt, clean the cell, or if the system has automatically entered its winter operation mode when cold water conditions exist (see pages 21-22).

SUPER CL MODE
Generally, it is not necessary to “shock” a saltwater pool. Occasionally, however, a large amount of sanitizer may be required to contend with rising chlorine demand, such as high bather loads, heavy rainfall, or other water conditions. In this case, simply activate the SUPER CL MODE. Press (+) to boost the Chlorine Output Level past 100%. The red SUPER CL LED will illuminate, and your system will begin to “super chlorinate” the water for 72 hours of run time. At the end of the SUPER CL boost period, the Output will reduce back to 100%; be sure to re-check your pool’s water chemistry and make any necessary adjustments.

MAINTENANCE

Expected Maintenance
Monitor your pool’s salinity level as frequently as you check your other water chemistry levels. After the system has run for a time, your cell will eventually need to be cleaned due to natural mineral scaling. The system will notify you of this by turning on the Service LED light. Visually check the cell for white mineral scaling, then follow the cleaning instructions below.
IMPORTANT: The frequency of cleaning depends on your water chemistry and the Saturation Index of the water. For most people, cleaning is only necessary a handful of times per season. The more rapid mineral build-up is a sure sign of a chronically high Saturation Index; it is possible for imbalanced chemistry to cause scaling to occur quite rapidly. Consult a pool professional for additional help.

Cleaning the Electrolytic Cell
As a natural result of the electrolytic process which creates chlorine from salt molecules, a white mineral build-up is attracted to the titanium plates in the Cell. The reverse polarity self-cleaning feature helps to inhibit such build-up and scaling. However, the attraction of minerals is inevitable, and eventually, it must be removed. To do so, follow these steps:
Note: Cleaning the Cell is only necessary to remove an excessive build-up of minerals on the plates. A light coating of minerals does not impede performance.
When removing the Cell for cleaning or replacement:

1. Turn off all power, and close supply line valves if applicable.
2. Unplug the Cell cable connecting the Cell to the Control Module.
3. Unscrew the Cell Cap (around the Cell cable) from the Cell Housing.
4. Slide Cell Plate Assembly away from the Cell Housing. DO NOT pull or hold the Cell Plate Assembly by its cable.

To clean the Cell of mineral buildup:

1. Slide the cleaning stick between titanium plates and connection brackets to loosen and dislodge any mineral buildup or scale.
2. Ensure that the O-Ring and its channel are clean and securely seated.
3. Reinstall the Cell into the Cell Housing, carefully aligning the Cell’s raised key into the Housing’s matching slot. Reattach the Cell Cap only hand-tight (do not use a wrench).

General Maintenance

Winterizing
Very little chlorine is necessary at low temperatures. The SJ-Series will automatically reduce its chlorine output in cold water conditions, and will not produce chlorine at very cold temperatures. Below 60° F, the Service LED indicator will be illuminated. This feature extends the lifespan of the Cell. Additionally, housing end-caps are available, which allow you to continue to run water through the plumbing without the Electrolytic Cell in place. (sold separately, available at www.circupool.com). If you “close” your pool for the winter, you can continue to follow all standard procedures for your local area.
The Electrolytic Cell will be damaged by freezing water just as your pool plumbing would. In areas that experience severe or extended periods of freezing temperatures, be sure to drain all water from the pump, filter, supply, and return lines before any freezing conditions occur. The Control Module is capable of withstanding any winter weather and does not need to be removed.

Spring Start-up
When opening the pool after a period of inactivity, do not power on and use the chlorine generator until the pool’s water chemistry has been balanced and brought to ideal levels. Salt must be added if water has been drained over the winter. Replacing the Cell When the titanium blades inside the Electrolytic Cell have reached the end of their lifespan, replacements are readily available so that the whole system does not have to be replaced. Replacements are easily switched out. To ensure quality and value, only genuine CircuPool replacement parts may be used

INSTALLATION

IMPORTANT: If you haven’t already done so, it is necessary to balance the pool’s water chemistry before the SJ-Series is powered on and used. See pages 6 – 8 for more information. The following are guidelines for the typical installation using 2” plumbing, which should be performed by a qualified individual. If 1.5” plumbing is present, reducers (not included) can be used to adapt the system; be sure to note the changes to any listed measurements or dimensions that the addition of reducers may cause. Your installation may vary depending on the space available and your specific arrangement of equipment. Double-check each measurement before cutting.

Overview

CAUTION: Ensure that the pool pump and all electrical power are turned off before installation.
TIP: Lay out your equipment and wiring to confirm placement and measurements first before cutting and gluing.
TIP: Be sure to clean & smooth cut pipe. Clean all parts with PVC Primer. When gluing PVC, parts will slip in place more easily once glue is applied. Be sure to apply firm, constant pressure between both glued parts for up to a minute to prevent potential slippage. Allow for glue to dry after each step.
IMPORTANT: These instructions are for 2” plumbing (typical). For installations using 1 ½” plumbing, you can simply use 2″-to 1 ½” reducer bushings (not included) to adapt the ports of the Cell Housing. For 1 ½” installations, be sure to note any new or additional measurements before cutting the pipe.

Installing the Electrolytic Cell
The Cell is to be fitted into the return line as the last piece of equipment the water passes through before returning to the pool: always after the pump, filter, heater (if applicable), etc. If a heater is present, all equipment must be a minimum distance away, per heater manufacturer recommendations. Lay out your equipment to ensure adequate pipe space, and that the Cell cable (approximately 10’) can reach back to where the Control Panel will be installed. The Cell should be positioned 6” above the highest plumbing point (includes filter ports or height of heater, if present), installed in the return line using two 90° elbows (not included) and two straight pieces of PVC pipe as risers (not included). The Cell must be installed horizontally with ports facing down. When positioning the Cell, the inlet side of the Cell Housing is imprinted with an arrow pointing up.

1. After determining the section of plumbing to install the Cell, measure out and mark the selected area. Cut a gap in the plumbing, so that you will be able to glue two 90° elbows on either side of the gap with a center-to-center distance of 5 ½”. Using standard 2” elbows, usually, this gap is approximately 8 ⅛”.

2. Glue each 90° elbow to the end of each pipe stub on either side of the cut gap; ensure correct center-to-center distance.
   TIP: Dry-fit riser pieces into Housing, and use the ends of the risers as a guide to align 90° elbows.

3. Glue each riser into the top of 90° elbows.

4. Glue Cell Housing down onto risers, ensuring that the Cell is level.

5. Ensure that the O-Ring is seated into the receiving channel in the Cell Housing. Slide the Cell into the Cell Housing, making sure to carefully align the raised key on the plastic head of the Cell with the matching slot in the clear Cell Housing. For a watertight seal, slide the Cell Cap into place and only tighten by hand- do not use tools or over-tighten, do not use lubricants on O-Ring

Wiring (Continued)
Wiring to Power Source: Always double-check the voltage of your power source. Connection to improper voltage can: a) cause severe damage/harm, or b) cause lights and screen to power on without system function. The SJ-Series is shipped from the factory with a 240 VAC configuration. If 120VAC is needed, move the internal jumpers as shown on page 18 (the white wire on the power cord becomes neutral). If unsure, seek professional advice. The Control Module comes with an un-terminated Power Cord (AC Input) which must be connected to an external timer, which will turn the pump and Control Module on and off together. Have the Control Module wired to the load side of the timer by a qualified person? See the following diagram for typical wiring

In some parts of the United States and Canada, the Control Module must be connected to a circuit protected by a Class A ground fault interrupter (GFI). Check local codes before connecting. For use with Variable Speed Pumps: When used with variable-speed or other electronically controlled pumps, use a timer to coordinate SJ run time with full-flow pump operation. Power Protection Mechanism: The Control Module has a power protection mechanism and an external Fuse Reset button located on the underside of the unit. If the Control Module has input power, but displays no power, press the external Fuse Reset button.

At this point, this installation of your equipment is complete. If the water has not yet been prepared, then you are ready to begin adding salt and balancing your water chemistry, see pages 6-8. Turn the Control Module to the Power Off mode until enough salt has been dissolved in the water.

Installing the Control Module
Mount the Control Module as close to the pump and filtration system as possible. For safety concerns, do not install the Control Module within 10 feet of the pool edges, and follow all applicable codes. Verify that the Cell cable can reach the Control Module from the section of pipe selected for plumbing. Using the mounting template as a guide, install screws at a comfortable level on a wall or vertical support, at least 3 feet above ground level. Once the screws have been secured, align the holes on the back of the Control Module and mount to the screws. The Module is fully rated for outdoor use; common sense considerations such as minimizing direct exposure to rain, sunlight, water runoff, and lawn sprinkler systems will enhance longevity. As with most electronics, avoid placing the controls in tightly enclosed spaces to avoid a build-up of excess heat. Do not mount it above the heater, if present.
TIP: Do not operate the unit until all salt is dissolved in pool water and salinity is verified between 4000-4500 ppm.

Wiring
CAUTION: Power must be shut off at the circuit breaker before performing any wiring. Be sure to follow local and NEC/CEC electrical codes. The system has been designed to easily wire into typical in-ground pool systems. To provide safe operation, the unit must be properly grounded and bonded. For operation, the Control Module must be wired into the pump’s power source so that both turn on and off together (see diagram on page 17). For variable speed pumps, use a timer to coordinate SJ run time with full-flow pump operation.

Electrolytic Cell Connection: The Cell cable has a plug-in connector, which attaches easily to the Control Module. Press the plug in firmly to ensure that the connector clicks into place across the length of the plug. Refer to the diagram below for the location of these connections. Fuse Reset Button: For protection, the Fuse Reset will trip in the event of a power surge. If the power switch is in the On position, but the controls are not illuminated, depress the rubber cover of the Fuse Reset Button until you feel a click. Bonding: A lug used for bonding is attached to the bottom of the SJ- Series Control Module. The Control Module must be bonded with an 8 AWG bare copper wire to the pool bonding system

VOLTAGE CONVERSION

Always double-check the voltage of your power source. Connection to improper voltage can: a) cause severe damage/harm, or b) cause lights and screen to power on without system function. All service should only be attempted by a person with appropriate electrical skills, with all equipment disconnected from power. The SJ Series is shipped from the factory with a 240 VAC configuration unless specially ordered. If 120VAC is needed, move the internal jumpers as shown below. If unsure, seek professional advice. \The voltage terminals can be accessed by opening the SJ Control Module; remove the two torx screws (T10) on the left and right side of the blue case to do so. The small Terminal Block is located in the corner of the Control Module. The factory voltage setting is the 240V configuration, with a wire jumper inserted between the second and third terminals. The Control Module can be made to accept 110V by adding a jumper (second wire jumper included with the manual packet) and reconfiguring them as shown above right, with two jumpers instead connecting the first & second terminals and the third & fourth terminals.
NOTE: Only jumper wires between screw terminals should be moved or reconfigured. No other wires should be moved or loosened. Ensure all connections are tight before returning the unit to service.

INSTALLATION CHECKLIST

• Cell housing installed and glued into pipe work.
• O-Ring seated in Cell Housing, Cell aligned with and inserted into Cell Housing, and Cell Cap screwed in place hand tight (Do not use wrench).
• The Control Module is affixed to the wall and wired correctly.
• Cell cable connected to Control Module.
• You have checked and confirmed that the Control Module switches ON and OFF concurrently with the filter pump (or when used with variable speed pumps is only energized during high water flow.)
• You have checked all connections and joints for leaks.
• Sufficient salt has been added fully dissolved and circulated throughout pool water.
• The pool has properly balanced water chemistry

HELPFUL HINTS
For more detailed information and useful tips, visit www.circupool.com/help.
Proper operation of the chlorine generator can be easily verified by checking the lights on the control panel. However, if the pool remains cloudy, or the chlorine residual tests low, then the chlorine being produced is being lost due to high chlorine demand or improper water conditions. To reduce the chlorine demand, check the pH and Stabilizer (Cyanuric Acid) readings. Check for phosphates and nitrates, which commonly contribute to severe chlorine demand. If tests show correct, then a shock treatment with an oxidizer agent is advised. Generally, superchlorination is not necessary if the pool is maintained at the correct levels.

Recommendations and Helpful Hints
Recommended List

• Read and keep your manual in a safe place.
• Increase Chlorine Production when the temperature goes up.
• Increase Chlorine Production when the number of guests goes up.
• Use a Stabilizer (Cyanuric Acid) to protect free chlorine in the pool.
• Mount the Control Module in the shade or out of direct sunlight whenever possible.
• Decrease Chlorine Production when the temperature goes down.
• Take a pool water sample to a Pool Professional at least once per month.

Not Recommended List

• Do not allow fertilizer anywhere near your pool. Fertilizers are one of many sources that contain Nitrates or Phosphates which cause severe chlorine demand in pool water.
• Never use dry acid to adjust pH. A build-up of by-products can damage the Cell.
• Do not add any chemicals (including salt) to the skimmers.
• Do not let the salinity level drop below 3500 ppm.

Definitions
Algae are Plant-like organisms that grow in water. Especially active in summer conditions, where chlorine disinfectant level is too low to destroy them. Algae may be green, brown, pink, or black (Black Spot) in color. Chlorine Demand The amount of chlorine that should be added to the water to provide proper bacteria and algae control. Chlorine Residual The amount of chlorine left over, after the “demand” has been met. Combined Chlorine Weak chlorine is combined with the contaminants in the water. Free Chlorine Active chlorine in the water with the potency to destroy contaminants. Shock Treatment The removal by means of oxidation of those materials that have chlorine demand. Superchlorination An extra large amount of chlorine is added to the water.
