Setup and Installation

  1. Positioning the Pump: Place the filter pump on a solid, level surface near your above-ground pool. Ensure it is at least 2 meters (6.5 feet) away from the pool edge and protected from direct sunlight and rain.

  2. Connecting Hoses: Connect the inlet and outlet hoses to the pump and the corresponding ports on your pool. Use the provided adapters if your pool has 3.2 cm valves. Ensure all connections are secure to prevent leaks.

  3. Installing Filter Media: Open the transparent lid of the pump. Carefully place the Polysphere filter balls inside the filter chamber. Ensure the chamber is filled according to the pump's capacity, typically 240g for this model.

  4. Securing the Lid: Once the filter balls are in place, securely fasten the transparent lid. Hand-tighten the black ring to ensure a watertight seal.

  5. Initial Priming (if necessary): Before plugging in, ensure the pump is filled with water. This may involve opening a small air release valve or allowing water to flow from the pool into the pump until it is full.

Operating the Filter Pump

Once installed and primed, the filter pump is ready for operation:

  1. Power On: Plug the pump into a grounded electrical outlet. The pump will begin circulating water, filtering out debris.

  2. Run Time: The recommended daily run time for optimal filtration depends on pool size and usage. For pools compatible with this pump (1,100 to 31,700 L), typically 4-8 hours per day is sufficient.
  3. Monitoring Filtration: The transparent lid allows you to visually inspect the Polysphere filter balls. If they appear dirty or the water flow decreases, it's time for cleaning or replacement.

Maintenance

Regular maintenance ensures the longevity and efficiency of your filter pump:

  • Cleaning Polysphere Filter Balls:

    Disconnect the pump from power. Open the lid and remove the Polysphere balls. Wash them by hand with clean water until they are free of debris. Do not machine wash. The balls are reusable and can last 4 to 6 months with proper care.

  • Replacing Filter Balls: Replace the Polysphere balls when they can no longer be effectively cleaned or if filtration performance significantly degrades.
  • Inspecting Hoses and Connections: Periodically check hoses for cracks or damage and ensure all connections remain tight to prevent leaks.
  • Winter Storage: Before winter, drain all water from the pump and hoses. Clean the filter balls and store the pump in a dry, frost-free location.
