Setup Instructions

Visit www.intexdevelopment.com/support/videos for the latest instructional video.

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. 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.

Installation Steps:

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. 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. If the pool is empty, proceed to step 6.
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. Reinstall the strainer grids to the strainer connectors.

Salt & Pool Water Volumes

Which kind of salt to use:

• Use only Sodium Chloride (NaCl) salt that is at least 99.8% pure. Water conditioning salt pellets (evaporated salt) are also acceptable but may take longer to dissolve.
• Do not use iodized or yellow (yellow prussiate of soda) colored salt.
• Salt is added to the pool water, and the electrolytic cell uses the salt to create sodium hypochlorite. Purer salt leads to better performance.

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 sodium hypochlorite 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.
• Refer to the "Salt Table" for correct salt dosage. The salt is constantly recycled.

Adding Salt:

1. Turn on the filter pump to start water circulation.
2. Keep the Saltwater System turned off.
3. Determine the amount of salt to be added using the "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.
7. Run the filter pump for 24 consecutive hours to dissolve the salt.
8. After 24 hours, if all salt is dissolved, turn on the Saltwater System. Press the button, then 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". Partially drain the pool and refill with fresh water (approx. 20%) until "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 reduces chlorine loss due to UV rays. Maintain cyanuric acid levels at approximately 0.35% of the salt level (e.g., 0.35 lbs of cyanuric acid for 100 lbs of salt). Do not add cyanuric acid if the pool water is dirty. If the water is dirty, BOOST the pool water first. Once clear, add cyanuric acid.

Intex Pools Operating Time Table (with Cyanuric Acid)

This table provides recommended operating times for the Saltwater System based on pool size and ambient temperatures.

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

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

Maintenance

IMPORTANT: Unplug the power cord before cleaning. Insert black hat-like plugs in the strainer opening to prevent water spillage. Plug the power cord back in and remove the plugs after maintenance.

Titanium Electrode Cleaning

The titanium electrode has a self-cleaning function. In most cases, this self-cleaning action maintains optimum efficiency. If the pool water is hard (high mineral content), manual cleaning may be required periodically. Inspect the titanium electrode (7) visually monthly.

Inspection and cleaning steps:

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

Diagrams: Six numbered diagrams illustrate the steps for removing and cleaning the titanium electrode.
