Setup Instructions

IMPORTANT

• The Saltwater System requires a separate filter pump [300~1000 gph (1136~3785 lph)] to drive the water and function properly.
• The Saltwater System must be installed as the last piece of pool equipment in the water return line to the pool as displayed below. This location extends the life of the titanium plates.
• Remove any large debris and particles such as leaves, sand, insects and bugs from the pool water first.

1. Assemble the above-ground-pool (AGP) and its filter pump according to their installation instructions.
2. Take the Saltwater System and its accessories out of the packaging.
3. Place the Saltwater System in line after the filter pump.
4. Connect the connector hose (2) to the Saltwater System inlet with a hose clamp (3).
5. Go directly to step 6 if your pool is empty. If your above-ground-pool is filled with water, unscrew the strainer grids from the strainer connectors and insert the black hat-like plugs into the connectors, before installing the saltwater pool system.
6. Disconnect the water return hose from the filter pump connection and connect it to the Saltwater System outlet.
7. Connect the connector hose (2) to the filter pump outlet connection with a hose clamp (3). Tighten securely.
8. Remove the black hat-like plugs that prevent water from flowing out of the pool. Now, return the strainer grids to the strainer connectors.

Salt & Pool Water Volumes

Which kind of salt to use:

A specific type of salt must be used in swimming pools to protect the equipment. When buying salt, check that the salt conforms with the EN16401 standard for Chemicals for use in swimming pools. Consult your local pool store or contact the salt manufacturer if you need help with verifying you have the correct salt. Do not use iodized salt, salt containing anti-caking agent (E535) or yellow (yellow prussiate of soda) colored salt.

When choosing the pool salt for use within the EU, please also note that the European Chemicals Agency (ECHA) requires that salt (sodium chloride) be used from registered/authorized manufacturers listed in the ECHA Article 95 List in accordance with the Biocidal Product Regulation (BPR, Regulation (EU) 528/2012). For more information, please consult ECHA's website at https://echa.europa.eu/information-on-chemicals/active-substance-suppliers.

Use only Sodium Chloride Salts

Use only sodium chloride (NaCl) salt that is at least 99.4% pure. It is also acceptable to use water conditioning salt pellets (the compressed forms of evaporated salt). However, it will take a longer time for them to dissolve. Salt is added to the pool water and the electrolytic cell uses the salt to create sodium hypochlorite. The purer the salt the better the performance of the electrolytic cell.

Optimum Salt Levels

The ideal salt level in the pool water is between 2500-3500 ppm (parts per million). The optimal level is 3000 ppm. A too low salt level will reduce the efficiency of the Saltwater System and result in low sodium hypochlorite production. A high salt level may generate a salty taste to the pool water (this may occur at a salt level above 3500-4000ppm). Too high salt level may damage the power supply and cause corrosion to the pool metal fixtures and accessories. The Salt Table page of this manual shows the correct dosage of salt needed.

Adding Salt

1. Switch the filter pump on to start the 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 proper amount of salt around the inside perimeter of the pool.
5. Avoid clogging the filter. Do not add salt through the skimmer.
6. Brush the pool bottom to speed up the dissolving process. Do not allow salt to pile up on the bottom of the pool. Run the filter pump 24 consecutive hours to thoroughly dissolve the salt.
7. After 24 hours and if all the salt is dissolved, turn on the Saltwater System, press code "00" flashing and set the saltwater pool system to desired operating time (see "Operating Time Table").

Removing Salt

If too much salt has been added, the unit will beep and display "Code 92" (see "Alarm Codes"). You will need to lower the salt concentration. The only way to do so, is to partially drain the pool and refill it with fresh water. Drain and refill approximately 20% of the pool's water until the "Code 92" disappears.

Pool Volume Calculation

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 is a chemical that reduces the loss of chlorine in water due to ultraviolet rays. To maintain the pool water clear and clean, and to maximize the performance of the device, add cyanuric acid to the pool. We recommend that the cyanuric acid level be maintained at approximately 0.35% of the salt, i.e. 100 Lbs (45 Kgs) salt x 0.35% = 0.35 Lbs (0.16 Kgs) cyanuric acid. If the pool water is dirty, filthy or grimy, DO NOT add chlorine stabilizer (cyanuric acid) as this will slowdown the sanitization time of the device. Under this condition you must BOOST your pool water, refer to BOOST cycle steps. Once the pool water has been restored to clear and clean conditions you may add cyanuric acid.

Intex Pools Operating Time Table (with Cyanuric Acid)

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

IMPORTANT

The filter pump running time should be 1 hour longer than the required operating time of the Saltwater System. NOTE: If an Intex filter pump has a timer on the GFCI, the maximum run time is 10 hours. The timer will need to be manually reset in order to extend the operating time.

LED Code Chart

IMPORTANT

When Code "90" alarm is shown, ensure the timer of the filter pump is set one (1) hour longer than the Saltwater System. If the filter pump does not have a built-in timer, the filter pump needs to be turned on/off manually every day.

Saltwater System Stationary Mounting

Some countries, especially in the European community, require the product to be secured to the ground or to a base in a permanent upright position. Check with your local authorities to determine if there is a regulation in your area regarding above-the-ground swimming pool filter pumps. If yes, then the product can be mounted to a platform using the two holes located in the base. See drawing below.

The product can be mounted on a cement base or onto a wooden platform to prevent accidental tipping. Total assembly must exceed 18kg.

Diagram: A drawing shows the base of the saltwater system with two mounting holes, indicating a spacing of 62 mm.

1. The mounting holes are 6.4 mm in diameter and spaced 62 mm apart.
2. Use two bolts and lock nuts with a maximum of 6.4 mm in diameter.

Maintenance

IMPORTANT

Unplug the power cord before cleaning your system. Also insert the black hat-like plugs in the strainer opening to prevent water spillage. After completing all maintenance tasks, you must plug the power cord back in and remove the plugs.

Titanium Electrode Cleaning

The titanium electrode has a self cleaning function incorporated into the electronic control's programming. In most cases this self cleaning action will keep the electrode working at optimum efficiency. If the pool water is hard (high mineral content) the electrode may require periodic manual cleaning. To maintain maximum performance, we recommend that you open and visually inspect the titanium electrode (7) monthly. The following steps provide instructions on how to clean your cell.

Inspection and cleaning:

1. Switch off the unit, unplug the power cord from the electrical socket.
2. To prevent water from flowing out of the pool, unscrew the strainer grids from the strainer connectors and insert the hat-like plugs into the strainer connectors.
3. Disconnect the 2 hoses from the Saltwater System (see drawings 1~3).
4. Unscrew the titanium electrode plug collar, disconnect the plug from the titanium electrode (7) (see drawing 4).
5. Unscrew the cell nut, remove the titanium electrode from the cell housing (see drawing 5).
6. Place the titanium electrode in a container and pour kitchen grade vinegar into the container until the titanium electrode is immersed. Soak for 1 hour and then flush with a high-pressure garden hose (see drawing 6).
7. Reverse steps 3, 4, 5 and 6 to reconnect the electrolytic cell.

Diagrams: Six diagrams illustrate the steps for cleaning the titanium electrode, showing disconnection of hoses, plug collar, cell nut, immersion in vinegar, and flushing.

Maintenance (continued)

Intex® Test Strips (Packed with the Product)

The Test Strips can test the "Free Chlorine", "pH", "Calcium Hardness" and "Total Alkalinity" levels at the same time. We recommend that you test the water chemistry weekly, and maintain the chlorine concentration at 1.0-3.0 ppm.

Directions and Use

1. Dip the entire strip into the water and remove immediately.
2. Hold the strip level for 15 seconds. Do not shake excess water from the strip.
3. Now compare the strip pad to the color chart on the packaging label. If necessary, adjust the chemical level in the pool water. It is very important, to use the proper technique when testing the water's chemical level. Read and follow the written strip instructions carefully.

Long Term Storage

1. Disconnect the power cord from the electrical outlet.
2. After the pool is completely empty, disconnect the Saltwater System from the hoses by reversing the installation instructions.
3. Air-dry the unit before you store it. This might be a good time to visually inspect and clean the electrolytic cell.
4. Store the unit and accessories in a dry place. The temperature should be controlled, between 32 degrees Fahrenheit (0 degrees Celsius) and 97 degrees Fahrenheit (36 degrees Celsius).
5. The original package can be used for storage.

Pool Maintenance & Chemical Definitions

Consult with local swimming pool dealer for water treatment.

• Free Chlorine - Is the chlorine residual present in pool water.
• Combined Chlorine - Is formed by the reaction of free chlorine with ammonia wastes. Result if too high - Sharp chlorinous odor, eye irritation.
• pH - A value that 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 degree of the water's resistance to change in pH. It determines the speed and ease of pH change, so always adjust total alkalinity before adjusting the pH level. Result if too low - Corroded metals, eye & skin irritation. Low alkalinity will cause the pH to be unstable. Any chemical added to the water will have an affect on pH. Result if too high - Scale formation, cloudy water, eye & skin irritation, poor chlorine efficiency.
• Calcium Hardness - Refers to the amount of calcium and magnesium dissolved in the water. Result if too high - Eye & skin irritation, difficulty balancing water and poor chlorine efficiency. Scale will form and will cause the water to become cloudy.
• Stabilizer - Stabilizers extend the life of chlorine in swimming pools. (Cyanuric Acid)

Do not add pool chemicals directly to the skimmer. This may damage the cell.

Maintaining a salt and sanitizer level above the recommended range can contribute to the corrosion of the pool equipment.

• Check the expiry date of the test kit as the test results may be inaccurate if the kit is used after that date.
• If, due to heavy pool usage, it is required to increase the sanitizer level, then use a chemical based on trichlor, TCCA or dichloro.
