Proper setup is crucial for the optimal performance of your saltwater system. Follow these steps carefully:
- Placement: Position the saltwater system on a stable, level surface near your above-ground pool and existing filter pump.
- Connection: Connect the saltwater system to your filter pump using the provided hoses. Ensure all connections are secure and watertight.
- Salt Addition: Add non-iodized pool salt directly to your pool water. The required amount will vary based on your pool's volume. Refer to the product specifications for guidance (e.g., up to 7,000 gallons). Allow the salt to dissolve completely before operating the system.
