Setup Instructions
Follow these steps to set up your Flowclear Filter Pump:
- Positioning the Pump: Place the filter pump on a solid, level surface at least 6 feet (1.8 meters) away from the pool. Ensure it is lower than the pool's water level to facilitate proper water flow.
- Connecting Hoses: Attach the two hoses to the pump's inlet and outlet ports. Connect one hose from the pool's water outlet to the pump's inlet (marked 'A' or 'IN'). Connect the second hose from the pump's outlet (marked 'B' or 'OUT') to the pool's water inlet. Secure all connections with the provided clamps.
- Installing Filter Cartridge: Unscrew the filter pump lid and insert the Type I-H filter cartridge. Ensure it is seated correctly. Replace the lid and tighten securely.
- Priming the Pump: Before plugging in, ensure the pump is filled with water. Open the air release valve on top of the pump until water flows out, indicating that air has been purged. Close the valve.
- Power Connection: Plug the pump into a grounded 110-120V electrical outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI).

Operating Instructions
The Flowclear Filter Pump is designed for simple operation:
- Starting the Pump: After setup, ensure the pump is primed and all connections are secure. Plug the pump into the GFCI-protected outlet. The pump will begin circulating water.
- Using the Timer: The pump features an energy-saving plug with a built-in timer. Refer to the timer's specific instructions for setting desired operating durations (up to 10 hours). This allows the pump to run automatically and shut off after the set time.
- Daily Operation: Run the pump for several hours each day to ensure proper filtration. The exact duration depends on pool size, usage, and water condition.

Maintenance
Regular maintenance is crucial for the longevity and efficiency of your filter pump:
- Filter Cartridge Cleaning: Unplug the pump before performing any maintenance. Unscrew the filter pump lid and remove the filter cartridge. Rinse the cartridge thoroughly with a garden hose to remove accumulated debris.
- Filter Cartridge Replacement: Filter cartridges should be replaced every two weeks, or more frequently depending on pool usage and water condition, to maintain optimal filtration performance.
- Inspecting Hoses and Connections: Periodically check hoses for kinks, cracks, or leaks. Ensure all clamps and connections are tight.
- Winterization: Before freezing temperatures, disconnect and drain the pump and hoses. Store all components in a dry, protected area.
