Important Safety Information
Always follow basic safety precautions when installing and using this electrical equipment.
- Adult Supervision: This product should only be operated under competent adult supervision.
- Electrical Requirements: Ensure the pump is connected to a properly grounded outlet. The pump operates on 240 Volts. Do not use extension cords.
- Water and Electricity: Never operate the pump when people are in the pool. Keep the pump away from the pool edge to prevent accidental submersion.
- Maintenance Safety: Always unplug the pump from the power source before performing any maintenance, cleaning, or servicing.
- Damage Inspection: Regularly inspect the power cord and pump for any signs of damage. Do not use if damaged.
Setup
Follow these steps to properly set up your Bestway Flowclear Filter Pump:
- Positioning: Place the filter pump on a solid, level surface, at least 2 meters (6.5 feet) away from the pool. Ensure it is lower than the pool's water level.
- Hose Connection: Connect the two hoses to the pump. One hose connects to the pump's inlet (marked with an arrow pointing towards the pump) and the pool's outlet valve. The other hose connects to the pump's outlet (marked with an arrow pointing away from the pump) and the pool's inlet valve. Use the provided adapters for 1.25"/32mm or 1.5"/38mm threaded valves.

- Secure Connections: Tighten all hose clamps to ensure a watertight seal.
- Air Purge: Open the air purge valve on top of the filter housing. Once water starts flowing out, close the valve. This removes air from the system.
- Power Connection: Plug the pump into a grounded 240V electrical outlet. Do not turn on the pump until all connections are secure and the pump is primed with water.

Operation
Once the pump is set up and primed, you can begin operation:
- Starting the Pump: Turn on the power switch. The pump will begin circulating water.
- Filtration Cycle: Run the pump for several hours each day to ensure proper water filtration. The recommended run time depends on pool size and usage. For pools with a capacity of 1,100 to 31,800 liters, this pump (5,678 L/h or 1500 gal/h flow rate) is highly effective.
- Monitoring: Periodically check the water clarity. If the water remains cloudy, increase the filtration time or check the filter cartridge.
Maintenance
Regular maintenance is crucial for the longevity and efficiency of your filter pump:
- Filter Cartridge Cleaning/Replacement: The filter cartridge (Type III, ref. 58012) should be cleaned every few days and replaced every 2-4 weeks, depending on pool usage and water quality.
- Steps for Cartridge Replacement:
- Unplug the pump from the power source.
- Close the inlet and outlet valves of the pool to prevent water flow.
- Unscrew the filter housing cap.
- Remove the old filter cartridge.
- Rinse the cartridge with a garden hose if cleaning, or insert a new one.
- Replace the filter housing cap and tighten securely.
- Open the pool valves and plug in the pump.
