PARTS REFERENCE

Before assembling your product, please take a few minutes to check the contents and become familiar with all the parts.

Diagram Description: A diagram illustrates the Intex Saltwater System components. It shows the main unit with numbered parts including the electrolytic cell housing, flow sensor, control station, and various connectors and adaptors.

When ordering parts, be sure to quote the model number and part numbers.

HOW THE CHLORINE IS GENERATED

This product is specially designed for above ground pools. It will destroy bacteria, oxidize bather organics, and control algae, providing a safe, clean, and comfortable swimming pool.

Common salt (sodium chloride) is composed of sodium and chloride. During installation, salt is dissolved in the pool water to make it slightly salty. The pool water flows through the Saltwater System's electrolytic cell (5) to produce chlorine. The chlorine dissolves in the water, instantly destroying bacteria and algae, and oxidizing other organic materials.

The secondary electrolytic cell enhances chlorination and sanitizing power for additional oxidation of water contaminants.

SALT & POOL WATER VOLUMES

Which kind of salt to use:

For use within the European Union, salt must be from an authorized salt supplier registered with the European Chemicals Agency (ECHA) - visit echa.europa.eu.

Use only Sodium Chloride Salts

Use only sodium chloride (NaCl) salt that is at least 99.8% pure. Water conditioning salt pellets (compressed evaporated salt) are also acceptable but take longer to dissolve. Do not use iodized or yellow (yellow prussiate of soda) colored salt. The purer the salt, the better the performance of the electrolytic cell.

Optimum Salt Levels

The ideal salt level is between 2500-3500 ppm (parts per million), with 3000 ppm being optimal. Too low a salt level reduces efficiency and chlorine production. A high salt level may result in a salty taste (above 3500-4000ppm) and can damage the power supply and cause corrosion to pool fixtures. The Salt Table shows the correct dosage. Salt is recycled and only lost when pool water is physically removed; it is not lost due to evaporation.

Adding Salt

1. Switch the filter pump on to start water circulation.
2. Keep the Saltwater System turned off.
3. Determine the amount of salt to be added (see "Salt Table").
4. Evenly spread the salt around the inside perimeter of the pool.
5. Do not add salt through the skimmer to avoid clogging the filter.
6. Brush the pool bottom to speed up dissolving. Do not allow salt to pile up. Run the filter pump for 24 consecutive hours to thoroughly dissolve the salt.
7. After 24 hours, if all salt is dissolved, turn on the Saltwater System, press the button until you hear a "beep", code "00" flashes, and set the desired operating time (see "Operating Time Table").

Removing Salt

If too much salt is added, the unit will beep and display "Code 92" (see "Alarm Codes"). Partially drain the pool and refill with fresh water (approximately 20% of the pool's water) until "Code 92" disappears.

Pool Volume Calculation

* The European Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) requires salt suppliers for on-site chlorine generation to be registered with the European Chemicals Agency (ECHA) and listed on Article 95 list.

INTEX POOLS SALT TABLE

This table shows the amount of salt needed to achieve and maintain the optimal 3000 ppm salt level.

INTEX POOLS CYANURIC ACID TABLE

Cyanuric acid reduces chlorine loss from ultraviolet rays. To maintain clear, clean pool water and maximize device performance, add cyanuric acid. The recommended level is approximately 1% of the salt, e.g., 100 Lbs salt x 1% = 1 Lbs cyanuric acid. If the pool water is dirty, do not add cyanuric acid as it slows sanitation. In such cases, BOOST the pool water. Once clear, add cyanuric acid.

INTEX POOLS OPERATING TIME TABLE (WITH CYANURIC ACID)

This table provides recommended operating times in hours for the Intex filter pump based on pool size and ambient/air temperatures.

MODEL: ECO5220/5230

MODEL: ECO6220/6230

IMPORTANT

The filter pump running time should be 1 hour longer than the required operating time of the Saltwater System.

MAINTENANCE

IMPORTANT

Unplug the power cord before cleaning. Close plunger valves or insert black hat-like plugs in strainer openings to prevent water spillage. After maintenance, plug the power cord back in and open plunger valves or remove plugs.

Flow Sensor Cleaning

1. Unscrew the collar of the flow sensor (6) counter-clockwise and remove it from the electrolytic cell conduit. Refer to "Part Reference".
2. If deposits or debris are visible on the flow sensor surface, wash it with a garden hose.
3. If flushing with water doesn't remove deposits, use a plastic brush to clean the surface and hinge. Do not use a metal brush.
4. After inspection and cleaning, align the flow sensor's locator notch with the connection ridge in the conduit. Turn the collar clockwise to tighten the sensor. Do not overtighten.

Electrodes Cleaning

The electrodes have a self-cleaning function integrated into the electronic control's programming. This usually keeps electrodes working optimally. For hard water (high mineral content), periodic manual cleaning may be needed. For maximum performance, visually inspect primary and secondary electrodes (5 & 4) monthly. The following steps detail cell cleaning:

Inspection and cleaning:

1. Switch off the unit and unplug the power cord.
2. For 1-1/4" (32mm) hose size filter pumps: Unscrew strainer grids and insert hat-like plugs into strainer connectors to prevent water spillage.
3. For 1-1/2" (38mm) hose size filter pumps: Turn plunger valve handles fully clockwise until they stop to close the valves and prevent water spillage.
4. Disconnect the 2 hoses from the Saltwater System. Attach cell covers (9) to the inlet and outlet of the electrolytic cell (3).
5. Unscrew the flow sensor collar (6) and pull the flow sensor from the electrolytic cell (3) housing.

POOL MAINTENANCE & CHEMICAL DEFINITIONS

Preferred Water Chemistry Reading

Consult a local swimming pool dealer for water treatment advice.

• Free Chlorine: The residual chlorine present in pool water.
• Combined Chlorine: Formed by the reaction of free chlorine with ammonia wastes. Result if too high: Sharp chlorinous odor, eye irritation.
• pH: Indicates how acidic or basic a solution is. Result if too low: Corroded metals, eye & skin irritation, destruction of total alkalinity. Result if too high: Scale formation, cloudy water, shorter filter runs, eye & skin irritation, poor chlorine efficiency.
• Total Alkalinity: Indicates the water's resistance to pH change. Adjust total alkalinity before adjusting pH. Result if too low: Corroded metals, eye & skin irritation. Low alkalinity causes unstable pH. Any chemical added affects pH. Result if too high: Scale formation, cloudy water, eye & skin irritation, poor chlorine efficiency.
• Calcium Hardness: Amount of calcium and magnesium dissolved in water. Result if too high: Eye & skin irritation, difficulty balancing water, poor chlorine efficiency. Scale formation can cause cloudy water.
• Stabilizer (Cyanuric Acid): Stabilizers extend chlorine life in swimming pools.

Do not add pool chemicals directly to the skimmer, as this may damage the cell.

Maintaining salt and sanitizer levels above the recommended range can contribute to pool equipment corrosion.

Check test kit expiry dates, as results may be inaccurate if used after the date.

For heavy pool usage requiring increased sanitizer levels, use chemicals based on trichlor, TCCA, or dichloro.
