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 EDGE 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 unit off when operating any plumbing control valves such as for
backwashing, water exhaust, or during operation of spa or water features. If 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 Cell.
•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
EDGE Series model.
•Proper pool chemistry must be maintained at all times. For outdoor pools, chlorine residuals can be protected from
destruction by sunlight by addition of 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 spa with water and repeat initial startup instructions on pages 6-8 of this manual.
•Ensure that the EDGE Series installation does not constitute a cross connection with the local potable water supply.
Consult local plumbing codes.
•Note: Some local codes may require 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.

EDGE SYSTEM OVERVIEW
The advanced compact EDGE salt system utilizes three main components for operation:
Complete System Includes:
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.
Flow / Temperature Sensor: These components ensure that there is adequate salinity & water flow for the Cell
to activate, and monitor the temperature in order to protect the cell.
Additional Items Required (Not Included)
Control Module
Electrolytic Cell
Flow/Temperature
Sensor
PVC Cement, PVC Primer, Hacksaw or Pipe Cutters, Screwdrivers, Permanent Marker

WATER CHEMISTRY & SALT LEVELS
Preparing the Pool Water
It is important that the pool's water chemistry is balanced before the EDGE
-
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 ideal salt level for operation is about 3500 ppm (parts per million), and it is suggested to keep the salinity
between 3000-4500 ppm . To achieve this level of salinity, use the chart on page 7, which will help you add
approximately 30 lbs of salt for every 1000 gallons of water (or 3.6 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 xPool Length xAverage Depth x7.5 = Pool Gallons
Round Pool
Pool Diameter xPool Diameter xAverage Depth x5.9 = Pool Gallons
Oval Pool
Pool Width xPool Length xAverage Depth x6.7 = Pool Gallons
Example –15’ x 30’ Rectangular Pool with 3’ shallow end and 6’ deep end.
15’ wide x30’ long x4.5’ Average Depth x7.5 = 15187 Gallons

7
Adding Salt
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
3500 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 EDGE
-
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 purer 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 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 existingsalt level 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 3000 - 4500 ppm 3000-4500 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) 30 - 50 ppm 30 - 50 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 in as quickly
as 2 hours. Stabilizer should not typically be kept above 50 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. Super Chlorinate (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.

How it works
Think of the EDGE
-
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 1) that the pool water is chemically balanced (see page 8) and 2) that
all installation items are completed (see page 18)
Press the power button on the EDGE controller while the circulation pump is running. This should activate the system and
within moments all LED lights should flash briefly while the system checks its status (if the pump is not running, you may
see the “system error” or “water flow” light). Once the system is on & ready to operate, the blue “on/off” LED will be solid.
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% (6 out of 8 blue lights) and adjust as needed over the initial startup 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 EDGE
-
SERIES, you can achieve the maximum performance for your pool.
There are three main factors that you can control which 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
- Including the amount of salt in the pool and chemicals that affect chlorine demand, such as chlorine stabilizer,
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 is 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 11).
Once the system detects that the Cell needs to be cleaned, it will display a “Clean Cell” warning light, and then will not be
able to create more chlorine until all mineral scaling has been removed from the Cell.
OPERATION

10
Using the Control Module
1) ON/OFF: Use this button to manually activate / deactivate the system on or off.
2) Adjust (Chlorine Output): Press to change the system's power level setting (the rate of chlorine production),
in order to customize operation for your pool's needs.
3) Boost (Chlorine Output): Press to activate/deactivate super-chlorination mode (maximum output for 24
hours of system run time). When pressed, boost mode is activated and the whole LED bar will be on. After
24 hours (of system run time), chlorine output will automatically return to previous setting.
4) Chlorine Output Power Level: Displays the system’s chlorine output level that you have chosen. These LED’s
are also used to display system diagnostics during troubleshooting.
5) System Messages: These LED lights display important information about the operations of your system. If any
of these orange LED lights are flashing or illuminated, please see the Troubleshooting section of this manual.
• CHECK CELL: Inspect for the Cell and soak the Cell in cleaning solution to remove calcium buildup or debris.
• LOW SALT: When this LED is illuminated, salt may need to be added to the pool. First, inspect the Cell for
mineral scaling and clean if necessary. If this does not solve the problem, manually check the salinity of
the pool water and add salt according to the table on page 7.
• SYSTEM ERROR: This LED is illuminated when the system is not able to produce chlorine or a critical fault
has occurred in the power supply. Please refer to the “Troubleshooting” section on page 20.
• WATER FLOW: When this LED is illuminated, the Flow Sensor is not being triggered by water flow. This
causes the Cell to stop generating chlorine. Verify that you have proper water flow without air bubbles in
the Cell housing, and verify that water flow is fully pressing the flow switch away from its resting center
position. In case you have a variable speed pump, increase flow until the LED turns off.

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 “CHECK CELL” light. When illuminated, follow the cleaning instructions below under
"Cleaning the Electrolytic Cell".
The frequency of cleaning depends on yourwater chemistry and the Saturation Index of the water. For most people, cleaning
is only necessary a handful of times per season. More rapid mineral build up is 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
Once substantial deposits have built up on the titanium plates in the Cell, the “CHECK CELL” light will illuminate, and the
mineral scaling must to be removed. The Cell may require cleaning even if debris or build-up is not immediately visible to
the eye. To do so, follow these steps:
IMPORTANT: If mineral build-up is severe, more than one cleaning may be necessary to dissolve remaining solids. Inspect
Cell plates closely with a bright light after cleaning. If you can see any remaining scaling, debris, or physical blockages
through Cell, repeat the cleaning process as needed. If “CHECK CELL.” comes back on soon after cleaning (check a few
minutes after restoring power): 1) verify salinity is in range; 2) ensure Cell is completely full of water during operation;
then 3) clean Cell again.
Before removing the Cell for cleaning or replacement:
1) Turn off all power to all pool equipment, close supply line valves if applicable.
2) Unplug the Cell cable connecting the Cell to the Control Module.
3) Disconnect the Cell by unscrewing the Threaded Collars around the unions where the Cell attaches to the plumbing.
4) Remove entire Cell from between the unions. DO NOT pull or hold the Cell by its cable.
To clean the Cell of mineral buildup:
1) Temporarily remove the O-ring from one end of the Cell.
2) Attach Cleaning Cap (included in box with the system) and orient the Cell vertically with the capped end on bottom.
Place on the ground and stabilize so as to remain upright and prevent spilling.
3) In a separate bucket, mix one part muriatic acid into four parts water. Pour this weak acid solution directly into Cell.
Ensure that the cleaning solution COMPLETELY covers the components the inside of the Cell.
4) Wait for foaming to stop. Allow solution to soak for no more than fifteen minutes.
5) Properly dispose of acid solution, and use a hose to generously flush any remaining debris out of the Cell.
6) Look inside the cell to check that no debris or scaling remains. Repeat steps 2-4 if necessary.
7) Reinstall Cell O-ring, and reinstall Cell into PVC return line.
MAINTENANCE
CAUTION: When cleaning the Cell always wear adequate protection, such as rubber gloves and eye protection.
Always add acid to water, do not add water to acid. Always work in a well-ventilated area. Splashing or spilling acid
can cause severe personal injury and/or property damage.
WARNING: Do not insert anything or use metal or other hard objects to clean the cell, this will void the warranty.

12
General Maintenance
Winterizing
Very little chlorine is necessary at low temperatures. The EDGE Series will not produce normal chlorine levels at
cold temperatures. This feature extends the lifespan of the Cell.
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 which
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 removed. Replacements are easily switched out.
To ensure quality and value, only genuine CircuPool replacement parts may be used.
When the cell has been run for enough hours of operation that it may be nearing the end of its usable lifespan,
the Check Cell LED light will begin to flash. No action is required; the Cell can continue to be used until a solid
warning light occurs. However, enough operation has occurred that you should consider purchasing a
replacement cell. The flashing LED light can be cleared by following the follow the Reprogramming instructions
on the following page.
Whenever a cell is eventually replaced, follow Control Module reprogramming instructions on the following
page.

13
Reprogramming the Control Module
When installing a new cell of the same size –or –clearing the flashing Check Cell LED:
This procedure will reset the system’s internal count of production hours. This should be done in order
to clear the Check Cell light when flashing and any time a new cell (of the same size) is installed.
1. Press the On/Off switch to deactivate the Control Module. (Leaving power on at power source)
2. Hold down the chlorine Adjust button until the LED’s on the chlorine output power graph light
up. Take note of how many LED’s are displayed: 1 LED (EDGE15), 4 LEDs (EDGE25), or 8 LEDs
(EDGE40).
3. Tap the Adjust button once, then let the Control Module sit until the lights turn off.
4. Hold down the Adjust button until the LED’s light back up on the chlorine output power graph.
5. Tap the Adjust button twice (confirm that the same number of LED’s are lit up as on Step #2
above), let the Control Module sit until the lights turn off, then hit On/Off button to turn unit
back ON.
6. Turn off power at the power source (breaker, timer, etc…) for about 30 seconds.
7. Turn power back on at the power source.
8. Allow the salt system and pump to run for at least 5 minutes to calibrate before shutting it off
again.
When installing a new cell of a different size:
If a different size cell is to be used (ex: upgrading to a new Cell of a larger size), the Control Module needs
to be set in order to work correctly with the new Cell size. Follow these instructions to change the Control
Module to the correct Cell Type.
1. Press the On/Off switch to deactivate the Control Module. (Leaving power on at power source)
2. Hold down the chlorine Adjust button until the LED’s on the chlorine output power graph light
up.
3. Press the chlorine Adjust button to set the Control Module to a EDGE15 (1 LED light displayed),
EDGE25 (4 LED lights displayed), or EDGE40 (8 LED lights displayed).
4. Once desired size is chosen, let the Control Module sit until the lights turn off, then hit On/Off
button to turn unit back ON.
5. Turn off power at the power source (breaker, timer, etc…) for about 30 seconds.
6. Turn power back on at the power source.
7. Allow the salt system and pump to run for at least 5 minutes to calibrate before shutting it off
again.

IMPORTANT: If you haven’t already done so, it is necessary to balance the pool's water chemistry before the EDGE
-
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 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 space available and your specific arrangement of
equipment. Double check each measurement before cutting.
Overview
Above are common installation configurations (#1-2). Be sure to avoid any configuration that may potentially allow water
to pass through the Flow Switch, but not the cell (#3-4). The main components of the EDGE-Series are the Control Module,
Electrolytic Cell, and Flow Switch.
INSTALLATION
1)

15
Installing the Electrolytic Cell and Flow Switch
The Cell and Flow Switch are to be fitted into the return line (horizontally or vertically) as the last pieces 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.
Refer to the overview diagram on page 14 for alternate configurations. For combined pool and spasystems with a spillover,
configurations #2 or #3 allow chlorination for both the pool and spa during spillover but preventing possible over-
chlorination when operating the spa only. Vertical Installation Kits are also available to minimize plumbing space required
and increase ease of installation (sold separately, available at www.circupool.com).
1. Lay out your equipment to ensure there is enough pipe space available.
2. On the pipe where the Cell will be installed, mark two lines 11” apart and then cut the pipe (for 2” plumbing).
3. Unscrew and removed Threaded Collars from Cell. Slide these over the pipe on each side of the cut, then glue each
Union to the cut pipe. Ensure O-Rings are in place on Unions.
-TIP: Glue one Union first, then when gluing second Union use Cell body to gauge the final distance need between
each Union; make small adjustments to second union’s slip connection while glue is still wet.
4. Only after the glue has fully cured, place the Cell into the opening between Unions and tighten the Threaded Collars
(by hand only) to ensure that the Cell fits securely in place. DO NOT OVER-TIGHTEN.
5. Install the Flow Switch next to the Cell. Ensure that any excess glue does not become contact with movable switch.
-IMPORTANT: If positioning the Flow Switch horizontally, you must orient the wires to be facing upwards.
•This portion is threaded and can be turned during service to align arrow with water flow; additional thread seal
tape may be added if necessary.
-IMPORTANT: When positioning the Flow Switch, ensure that there is no valve between the Cell and Flow Switch.
-IMPORTANT: When positioning the Flow Switch, it should be upstream from the cell and there must be at least 6 to
12” (30cm) of straight pipe before the Flow Switch.
-To ensure proper operation, verify that the arrow on the flow switch points in the direction of water flow; the
water flow must depress the hinged activator inside of the Flow Switch.
IMPORTANT: These instructions are for 2” plumbing (typical). For installations using 1 ½" plumbing, you will use 2"-
to-1 ½" reducer bushings to adapt the Cell Unions and Flow Switch. For 1 ½” installations, be sure to note any new or
additional measurements before cutting pipe.
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. When gluing PVC, parts will slip in place easier once glue is applied. Be sure
to apply firm, constant pressure between both glued parts for up to a minute to prevent potential slippage.

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 and Flow
Switch cables can reach the Control Module from the section of pipe selected for
plumbing.
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 above a heater or in tightly enclosed or insulated spaces to avoid a build-
up of excess heat.
Using screws and anchor hardware kit (included), secure the Control Module's
mounting bracket at a comfortable level on a wall or vertical support, at least 3
feet above ground level. Hang Controls on bracket.
Connecting to Power
CAUTION: Power must be shut off at the circuit breaker before performing any wiring. Be sure to follow local and
NEC/CEC electrical codes. It is best that the outlet be wired parallel to the pump so both the unit and pump are working
simultaneously. The system has been designed to easily wire into typical in-ground pool systems. To provide safe
operation, the unit must be properly grounded. The Control Module uses a switch-mode power supply designed to
automatically accept either 120VAC or 220VAC.
Electrolytic Cell and Flow Switch Connections:
The Cell and Flow Switch cables have easy plug-in connectors, which attach easily to the Control Module. Refer to the
diagram below for the location of these connections. Carefully align each connector to avoid damage.
For the Cell, connect the two black wires from the
Control Module to the two Quick-Connects on the
sides of the Cell. Ensure the connections are
perfectly clean of any debris. The two cell cable
wires are interchangeable.
For the Flow/Temp. Sensor, Find the sensor cable
from the Power Supply with the 2 small connect
terminals and connect them to their respective
connectors; these cables can only be connected to
one way to their corresponding sensor connector.

17
Connecting to Power (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.
For operation, the Control Module may be wired in to the pump's power source so that both turn on and off together, or
energized continuously for use with variable speed pumps (Flow switch will control Cell power but lights will remain on).
The Control Module comes with an un-terminated Power Cord (AC Input) which is typically 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, you may
wish to wire the Control Module directly to your power source. This will allow the pump to determine when the Cell is
energized or dormant by activation of the Flow Switch.
Power Protection Mechanisms:
The Control Module’s advanced digital switch-mode power supply has built-in power protection mechanisms. There are
no additional fuses or circuit breakers that you need to access on this unit..
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.

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) reading. 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 correct levels.
Recommendations and Helpful Hints:
Recommended List
• Read and keep your manual in a safe place.
• Increase Chlorine Production when temperature goes up.
• Increase Chlorine Production when number of guests goes up.
• Use Stabilizer (Cyanuric Acid) to protect free chlorine in pool.
• Mount Control Module in shade or out of the direct sunlight whenever possible.
• Decrease Chlorine Production when temperature goes down.
• Take 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 salinity level drop below 3000 ppm.
