Safety Information
Always read and follow all safety instructions provided in the full manual before installation and operation. Ensure the pump is connected to a grounded power source. Do not operate the pump if it or the power cord is damaged. Keep children away from the pump during operation.
Setup and Installation
Before beginning installation, ensure all components are present. The pump is pre-assembled for quick setup. You will need to add approximately 8.5 kg of #20 silica sand (0.45 to 0.85mm) or Bestway Polysphere pool filtration spheres to the filter tank (not included).
Components Included:
- Bestway Flowclear Sand Filter Pump
- ChemConnect Sand Filter Pump Diffuser
- Hoses and clamps for connection
Installation Steps:
- Place the pump on a solid, level surface near your pool.
- Fill the filter tank with the recommended amount of filter media (sand or Polyspheres).
- Connect the hoses from the pump to your pool's inlet and outlet ports. Ensure all connections are secure to prevent leaks.

Operating Instructions
The Flowclear Sand Filter Pump features a 6-position valve for various operational modes. Always turn off the pump before changing valve positions.
Valve Functions:
- Filter: Normal filtering operation. Water flows through the filter media and returns to the pool.
- Closed: Shuts off all flow to the filter and pool. Use for maintenance or when the pump is not in use.
- Rinse: Used after backwash to rinse the filter media and send water to waste.
- Drain: Drains water directly from the pool to waste, bypassing the filter.
- Backwash: Reverses water flow through the filter to clean the filter media and send dirty water to waste.
- Circulate: Circulates water through the pump and back to the pool, bypassing the filter media. Useful for chemical distribution.

For optimal water clarity, it is recommended to operate the pump for a few hours daily, depending on pool size and usage. Many users find success running the pump for 2 hours before swimming and 2 hours after.

Maintenance
Regular maintenance ensures the longevity and efficiency of your sand filter pump.
Routine Cleaning:
- Backwashing: When the pressure gauge indicates a higher-than-normal reading (typically 5-10 PSI above starting pressure), it's time to backwash the filter. This reverses the water flow to clean the sand.
- Rinsing: After backwashing, always perform a rinse cycle to settle the sand and remove any remaining dirty water before returning to filter mode.
- Pre-filtration Basket: Periodically check and clean the pre-filtration basket to remove large debris like leaves and hair, preventing them from entering the main filter tank.
If using Polysphere filtration spheres, they can be washed and reused multiple times, offering a convenient and cost-effective alternative to sand.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow / Poor filtration | Dirty filter media; Clogged pre-filter basket; Air in the system; Incorrect valve setting. | Perform backwash and rinse; Clean pre-filter basket; Bleed air from the system; Ensure valve is set to "Filter". |
| Water not clearing | Insufficient filtration time; Improper chemical balance; Filter media needs replacement. | Increase pump run time; Test and adjust pool chemicals; Consider replacing sand (every 3-5 years) or Polyspheres. |
| Pump not starting | No power; Tripped circuit breaker; Motor issue. | Check power connection; Reset breaker; Contact customer support if motor issues persist. |
