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) during installation. 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. Ensure that the lowest speed of a variable-speed pump provides sufficient flow.
WARNING: The use of isolation valves are strongly recommend against. 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.
  • If additional chlorine is required (due to heavy bather loads, for example), use Sodium Hypochlorite to maintain an appropriate chlorine residual in the water.
  • Check the expiration date of any test kits as test results may be inaccurate if used after that date.
  • 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.
  • DO NOT add acid or other concentrated chemicals directly to the skimmer. This may damage the Cell.
  • Ensure that the chlorine generator 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 power pack must be grounded.
  • To reduce the risk of personal injury, the power pack must be installed and wired to the load side of the clock or the load side of the relay. Ensure that the chlorinator operates only when the circulation pump is operating.
  • All metal parts installed on site, such as railings, ladders, drainage pipes or other similar hardware located within 10 feet (3 meters) of swimming pools, spas or hot baths, should be connected to the equipment grounding bus, American AWG/ Canadian 6 AWG, with a copper conductor not less than 8.

Please note, the total working hours for a properly-sized chlorine generator should ideally be less than 8 hours total per day. Total working hours can be approximated by total run time multiplied by the chlorine output percentage. If you are using a variable speed pump with long run times (ex: 24 hours a day), be sure to adjust down the chlorine output so as to avoid over-use and over-chlorination (ex: 30% output at 24 hours a day).

WATER CHEMISTRY

CHEMISTRY NOTICE
It is important that the pool’s water chemistry is balanced before the APEX P-CELL 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. In order to achieve normal pool operation, water chemistry needs to be balanced.
IDEAL WATER CHEMISTRY LEVELS

Free Chlorine 1-3 ppm
Combined Chlorine 0
PH 7.2-7.8 (7.5 target)
**Calcium Hardness** 50-300 for vinyl

220-320 for fiberglass
350-450 for plaster
Total Alkalinity| 60-180 ppm
Salt Level| 2600-4500 ppm (3400 target)
Cyanuric Acid| 30-50 ppm
Phosphates / Nitrates| None
Saturation Index| -0.2 to +0.2 (0 target)
Metals| None
TDS| <1000

WATER CHEMISTRY RECOMMENDATIONS
WHEN POOL HAS BEEN IN OPERATION PRIOR TO CELL REPLACEMENT: Double check your pool’s salinity level using independent testing. It is possible that the salinity level in the pool is higher than the previous cell has been reporting, as failing salt cells can incorrectly display low salt levels.
Especially if salt has recently been added because a failing salt cell has been reporting low salt warnings, it is possible to receive high salt warning from a new replacement cell – this does not indicate a problem with a new cell.
Similarly, salt system controls may continue to read the previous salinity levels (if an “average” salinity is displayed). The salinity levels displayed by the system may update slowly over 24 hours of operation.
WHEN POOL HAS NOT BEEN IN OPERATION PRIOR TO CELL REPLACEMENT : If a pool has not been attended to or in operation or due to winter or lack of use, it is especially important to remove any algae / organic debris and balance all water chemistry levels as a first step. While the cell may be used to generate chlorine as long as there are sufficient salinity levels, the sanitation demand otherwise may be higher than the cell’s chlorine generation alone is able to compensate for. If significant “shocking” is required during this startup period, this may be achieved quicker with an external chlorination source.
NEW POOL WATER: Should the pool be newly filled or refurbished, pools may contain undesirable substances. Such undesirable substances may interfere with the cell’s ability to properly chlorinate.
Before turning on the salt system, make sure the water has been tested and that all water chemistry levels are properly balanced. Should the pool be newly resurfaced, consult with the builder for a curing wait time before salt may be added (typically at least 30 days); conventional chlorination may be used in the meantime.
COMBINED CHLORINE : This level should be zero, as it negatively affects disinfection in the water. If a level is measured, it indicates that the sanitation demand (chlorine demand) of the water has been exceeding the rate of chlorine generation of the system. If this is the case, be sure to increase the chlorine output setting and/or system run time appropriately. Combined Chlorine levels also may form when excessive levels of urine and sweat from swimmers.
CYANURIC ACID: This is needed in outdoor pools to help stabilize and maintain proper levels of chlorine. Within two hours, UV rays from the sun will destroy 90% of the unstable chlorine. Cyanuric acid stabilizes the chlorine in the water and prevents UV degradation. Excessive levels, however, can significantly weaken the disinfection performance of chlorine and so should be maintained at the minimum required levels. It should not be used in indoor pools.
NITRATES AND PHOSPHATES : These common substances can cause extremely high chlorine demand, which can deplete the pool of free chlorine.
METALS: Certain metals, such as copper and iron, can cause chlorine loss. In addition, metals can stain your pool or damage the cell.
SALT LEVELS REQUIRED
What kind of salt?
It is important to use only 99% pure sodium chloride (NaCl). Pool salt is commonly found at hardware stores, as well as water softener salt; do not however use rock salt, salt containing more than 1% Sodium Ferrocyanide / Yellow Prussiate of Soda or anti-caking additive, or iodized salt. Salt pellets or granules can be used; smaller grains dissolve faster.
How Much Salt to Use?
Use the table below to determine how much salt is needed. Pool owners must always test the salt level independently before adding salt: most pools contain some salt, depending on the water source and the chemicals used to disinfect it.
A target salt level of 3400-3500 ppm is recommended for optimal water quality.
Low salt concentrations below 2300 ppm or above 6000 ppm will cause the unit to shut down.
IMPORTANT: Before adding salt at any time, ALWAYS perform an independent water test to measure pre-existing salt levels.

salt

Note: Salt measurement values will vary depending on the measuring device (salt test strips, electronic testers and titrators). Readings between test sources can be within +/- 300 ppm.
Unsure of your pool size? Determine the size of the pool (gallons of water in the pool)

Rectangular Pools Length x width x average depth x 7.5
Round Pools Diameter x diameter x average depth x 5.9
Oval Pools Length x width x average depth x 6.7
Angled walls Multiply total gallons by 0.85 (estimated)

How to Add or Remove Salt
It is best to add salt in the shallow portion of the pool or in an area with the most circulation, moving around as salt is added to help disperse and distribute the salt so as to prevent it being piled up at the bottom of the pool. Brushing the salt can help it dissolve quickly, though it is not necessary. Keep your pump and filter running until all salt has dissolved; this can take 24 – 48 hours on average.
Do not add salt directly to skimmers or to the main drain. This can shorten the life of the cell due to high salt concentration and reduced pump flow.

INTRODUCTION

The APEX P-CELL consists of an electronic controller mounted on top of a salt cell. The body of the salt cell has an easily accessible flow switch/sensor, as well as threaded connections which allow the P-CELL to be easily attached to plumbing unions.
Electronic Controller: The controller has an LED screen that provides adjustable chlorine output in 10% increments, diagnostics and readings. Additionally, LED indicators will provide warnings to aid in troubleshooting. The controller also has an internal fuse to provide additional protection for the electronics.
Salt Cell: The salt cell is what houses the titanium electrodes, which is where the chlorine generation takes place. When it reaches the end of its lifespan, the salt cell body is replaceable independent of the electronic controls and flow switch/sensors, to help minimize lifetime equipment costs.
Flow Switch / Sensor: Mounted to the salt cell body, the flow switch ensures that water is circulating before chlorine generation is allowed to take place. Additionally, the integrated sensor helps improve system operation and diagnostics. The flow switch is directional and must face the correct direction of water flow.

UnionAPEX P-CELL has self-cleaning cycle, which can reverse polarity and reduce calcium accumulation.
This function turns the cell on and off regularly to minimize the accumulation of calcium and scale and further extend the cell life.
WARNING: Make sure you have disconnected all power before performing any installation, component replacement, or service.
Please read all safety precautions, warnings, and important instructions, including original requirements if replacing a third-party component. Be sure to read and observe the safety instructions before accessing any electrical wiring. Installation must be done by a qualified individual.

SETUP

Replacing a Cell (existing installations):
Please note when the cell is used for aftermarket replacement, it is not normally necessary to install the cell; the cell will connect to existing threaded couplers.

  1. When the entire pool system is off and depressurized, unscrew the female threaded collars from the existing salt cell. Remove the existing salt cell from the plumbing. Ensure that the plumbing union o-rings are in good condition; replace if necessary.
  2. Place the P-CELL between the existing unions and threaded collars, ensuring that P-CELL is oriented so that water will be flowing through it in the correct direction.
  3.  Tighten the existing female threaded collars on to the P-CELL to ensure that the P-CELL fits securely in place. Hand-tighten only, DO NOT OVER-TIGHTEN.

Connecting the APEX P-CELL Cell Cable to the Power Center
Warning: Ensure power is off and disconnected from all equipment before removing or attaching any cables.

  1. Disconnect the existing cell cable from the existing power center.
  2. Before connecting the new cell cable to the power center, align the two (2) pins of the cell power cord connector with the socket on the top of the power supply.
  3. Center and insert the connector. Turn the round socket nut until the connector is locked in place.

IMPORTANT : Ensure that the chlorine generator system is setup so as to run in tandem with the circulation system. An external pool pump timer is typically required.
Please note: These P-CELL’s electronic controls are not designed to connect to automation.
Please note : After restoring power the equipment, be sure to visually check whether there is leakage around the cell unions.

CHECK SALT (Green) :This LED status confirms that the pool water’s salinity is within the operational range of 2800PPM – 4500PPM.
CHECK SALT (Red, flashing): This LED indicates that the salinity is outside of operational range (2300 PPM to 2800 PPM / 4500 PPM to 6000 PPM).
CHECK SALT (Red, steady): This LED warning means that the salinity is below 2300 PPM or above 6000 PPM.
CHECK CELL (Green): This LED indicates that the cell is operational and is able to generate chlorine.
CHECK CELL (Red): This LED warning means the cell needs to be inspected. In this state, the cell cannot generate chlorine. The titanium plates may have mineral scaling that needs to be removed.
FLOW (Green): This LED indicates that there is enough water flow to generate chlorine.
FLOW (Red, flashing): This LED indicates that while water flow is detected, the flow of water either just started or is unstable. Continuous detection of water flow for one minute must occur before the FLOW light will turn green.
FLOW (Red, steady): This LED warning means water flow is not detected and/or air is present in the cell.

OPERATION

The APEX P-CELL should be set so that enough chlorine is generated in order to disinfect the pool water every day; this is achieved when the free chlorine level in the pool is maintained between 1 – 3 ppm.
Output Settings and Adjustments
The rate at which the P-CELL is generating chlorine (out of its 100% maximum capability) is displayed on the LED screen. To adjust the output, press the CHLORINE OUTPUT UP (+) or CHLORINE OUTPUT DOWN (-) button. Please note that when you adjust the chlorine output, the system will perform diagnostics for 30 seconds before it resumes chlorine generation.
Making Adjustments at Start-Up
After the P-CELL has been added to the pool system and is operational, take note of what the current Free Chlorine level is in the water, allow the system to operate according to its normal daily schedule for 24 hours, and then re- check the Free Chlorine level. If the Free Chlorine level is too low, increase the P-CELL’s output setting; if the Free Chlorine level is too high, decrease the P-CELL’s output setting. This process usually needs to be performed a number of times within the first week of operation to find your pool’s currently ideal output setting. After this, typically only seasonal adjustments are needed; after periods of heavy use or bad weather, consider using the P-CELL’s SuperCL mode to temporarily boost chlorine output in order to compensate for periods of  temporarily higher chlorine demand.
Please note that if at initial start-up you check the Free Chlorine level and the result is low, consider setting the P-CELL’s output setting to 100% until 1-3 ppm is reached, and then perform the above procedure to find your pool’s currently ideal chlorine output setting. If the initial Free Chlorine level is zero, consider a supplemental chlorine source depending on the pool’s conditions.
Please note that if the pool pump has very long run times or runs continuously for 24 hours, it is likely that the P-CELL will produce more chlorine than most swimming pools’ need (1-3 ppm). This will unnecessarily shorten the lifespan of the cell. Be sure to set the system to the minimum required output setting in order to maintain 1-3 ppm Free Chlorine in the water.

EXPECTED MAINTENANCE

After your P-CELL has been put in to use, the following items should be attended to in order to ensure proper operation and longevity of your cell.
Water Balance
Continue to monitor your pool’s water chemistry balance as normal. Frequent testing is still important in order to proactively address potential issues. However, a properly used chlorine generator system should allow consistent and predictable Free Chlorine levels.
Note: the chlorine generator system is not monitoring and controlling either your Free Chlorine level or any other water chemical levels.
All water chemistry levels are critical to maintain, but with regards to the P-CELL, the following are relevant for the system’s maintenance.
Free Chlorine Level
Your responsibility as the owner of a chlorine generator system is to monitor the resulting Free Chlorine level in the swimming pool, and to keep the system set to an output level that matches chlorine demand of the water so as to keep a 1 – 3 ppm residual level in the water.
You should expect to make seasonal adjustments to the output setting to correspond to rising or falling temperatures. Low temperatures require less chlorination, warm temperatures require more chlorination.
You should expect to make adjustments after events such as bad weather or heavy pool usage. These events can require more chlorination to compensate for more impurities being introduced to the pool. If the need is temporary, the SuperCL mode can be activated to provide maximum chlorine output for 24 hours, after which the system will revert to its previous output setting.
Salinity
Salt in the water is not consumed during the chlorine generation process and does not need regular replenishment. However, pool water gets diluted by rain as well as any type of draining and refilling (not counting evaporation). Over time it would be expected for salinity levels to slow fall. Check your pool’s salinity levels as often as your other water chemistry, and especially after rain storms.
Chlorine Demand
So that your chlorine generator does not have to work harder than necessary, and so that you avoid problematic water chemistry that allows for cloudy or green water conditions, prevent excessive chlorine demand caused by common water chemistry issues such as the presence of phosphates or nitrates in the water (0 best), low or high pH (7.5 target), or low or high chlorine stabilizer levels (typically 30-50ppm).
Saturation Index (LSI)
For your pool system as well as your chlorine generator, ensure a balanced LSI (0 target). This prevents excessive mineral scaling as well as damaging chemical erosion.
Cell Cleaning
The P-CELL is a reverse-polarity self-cleaning electrolytic cell, and should experience the slow accumulation of mineral scaling at a rate comparable to other cells you may be experienced with. Like all salt cells, it eventually may become necessary to clean and remove the mineral scaling from the cell. How frequently this happens is based on your water chemistry’s Saturation Index (LSI), which can change over time; the rate of mineral scaling does not indicate that the chlorine generatoris or is not operational. It is generally recommended that the cell be removed for inspection at least twice a year.
Remove calcium buildup from the cell before acid cleaning: Use a typical garden hose with a powerful spray nozzle, and spray directly into the ends of the cell. Much of the calcium mineral scaling can have a soft consistency, which can be blown out of the cell. This also helps to remove any debris which may have passed through the pool filter and become trapped inside the cell. Once most of the calcium has been removed, continue with acid cleaning, which will now be more effective.
Acid Cleaning: A small amount of scale formation is normal. If a look through the P-CELL reveals scale formation between the titanium plates, the P-CELL must be cleaned according to the following instructions. It is important to take all necessary safety precautions such as: always wear rubber gloves and goggles when handling or using acid; always add acid to water, do not add water to acid.

  • Disconnect the AC power from the power center.

  • Disconnect the P-CELL from the power center, and disconnect the P-CELL from the plumbing.
    Remove the P-CELL’s flow switch from the cell body, and replace it with the cleaning cap included with the cell. Ensure that the o-ring is present between the cap and the flow switch port.

  • Connect the P-CELL to a compatible cleaning stand (available at apexpool.com). Ensure that the cleaning stand’s o-ring is present. Hand-tighten the cell to the cleaning stand.

  • Place the cleaning stand, with the cell attached and upright, down into a 5 gallon bucket in order to contain any spills. Ensure that the assembly is stable.

  • Mix one (1) quart of hydrochloric acid with one (1) gallon of tap water in a plastic bucket.

  • Carefully pour the acid solution down into the cell. Fill the interior of the cell with the cleaning solution, ensuring that the titanium plates are covered.

  • Note: The acid should only be in contact with the inside of the P-CELL. Acid should not come in to contact with any metal components of the cell cable’s connector. Try not to spill acid on the outside of cell. If acid does spill on the outside of cell, please clean it with water.

  • The cleaning solution will begin to foam as it dissolves the mineral scale (calcium carbonate) on the titanium plates. Cell cleaning should typically take 10-15 minutes. If foaming stops within this time, the process is likely complete and you can move to the next step. If foaming still continues after this time, there may be excessively heavy mineral scaling; allow the cell to soak up to 30 minutes, and be sure to very thoroughly rinse the cell out to remove any remaining scale. On rare occasions excessive scaling may require additional cleanings. Do not leave the cell unattended or allow unnecessary cleaning or excess time soaking in acid, as this can damage the titanium plates.

  • Take the P-CELL out of the bucket and put it into a 5 gallon bucket. Thoroughly rinse the inside and outside of the P-CELL with a garden hose and inspect the inside of the cell. If mineral scaling deposits are still visible, repeat the acid cleaning process.

  • After cleaning is complete, replace the P-CELL in the plumbing, ensuring it is fully connected. Reconnect the P-CELL cell cable to at the power center, then restore AC power. The system can return to normal operation.

Advanced: Salinity Calibration (not recommended unless instructed by a professional)
Do not perform this procedure until you have ensured that your cell is thoroughly cleaned and free of mineral scaling and debris. Do not perform this procedure until you have performed multiple independent salinity tests to positively confirm the water’s salinity level; titration testing is recommended. Also remember that differences of +/- 300ppm between different test sources is to be expected. If after these conditions have been met it is required to calibrate the salinity reading, please press “-” and “+” at the same time, and press several times quickly. When the display shows “SALT Tsys:” and a calibration number. This calibration number is inverse, so you will press “+” to lower the salinity, and press “-” to increase the salinity. For example, pressing “+” to make the calibration number 150 will lower the salinity reading by 150ppm. Alternatively, pressing “-” would make the calibration number raise the salinity reading.
