4. Setup and Installation
Proper installation is crucial for the efficient operation of your sand filter pump. Refer to the detailed installation guide video for visual assistance.
4.1 Site Selection
Place the sand filter pump on a firm, level surface, as close to the pool as possible. Ensure adequate drainage and protection from direct weather exposure.
4.2 Sand Loading
Before adding filter sand, ensure the standpipe is centered inside the tank. Fill the tank approximately halfway with water to cushion the sand as it is added. Carefully pour 150 lbs of #20 silica sand (0.45-0.55mm) into the tank. Ensure the sand level is below the top of the standpipe.
4.3 Multi-Port Valve Installation
Carefully place the 6-way multi-port valve onto the top of the filter tank, ensuring the standpipe aligns with the opening in the valve. Secure the valve to the tank using the provided clamp and bolts.
4.4 Connecting Hoses and Adapters
The pump is compatible with various pool types and hose sizes. Use the appropriate adapters from the included set for your specific pool setup.
- For above-ground pools, use the 1-1/4" or 1-1/2" clamped hose adapters.
- For in-ground pools, use the 1-1/2" or 2" PVC pipe adapters.

5. Operating Instructions
5.1 6-Way Multi-Port Valve Functions
The 6-way valve allows for various operational modes. IMPORTANT: Always stop the pump before switching the valve position to prevent damage.
Image 5.1: The 6-way multi-port valve, indicating its various settings for pool operation and maintenance.
- FILTER: Normal filtering mode. Water is pumped through the sand filter and returned to the pool.
- WASTE: Bypasses the filter, sending water directly out of the waste port. Used for vacuuming heavy debris or lowering pool water level.
- CLOSED: Shuts off all flow to the filter and pump. Use only when the pump is off and for servicing.
- BACKWASH: Reverses water flow through the filter to clean the sand bed. Water is discharged through the waste port.
- RECIRCULATE: Bypasses the filter, circulating water directly back to the pool. Used for chemical distribution without filtering.
- RINSE: Used after backwashing to flush out any remaining debris from the filter lines before returning to FILTER mode.
5.2 Automatic Timer Operation
The integrated timer allows for automated filtration cycles. It features 9 settings, ranging from 2 to 24 hours.

- Ensure the pump is connected to a power source.
- Rotate the timer dial to select the desired running hours (e.g., 2, 4, 6, 8, 10, 12, 14, 16, 24 hours).
- The pump will automatically start and stop according to the selected schedule.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your sand filter pump.
- Backwash Regularly: When the pressure gauge reads 8-10 PSI above its clean operating pressure, it's time to backwash the filter.
- Rinse After Backwashing: Always perform a RINSE cycle for 30-60 seconds after backwashing to settle the sand and prevent debris from returning to the pool.
- Inspect Connections: Periodically check all hose and pipe connections for leaks and tighten as necessary.
- Winterization: In cold climates, drain all water from the pump and filter to prevent freezing damage. Store the pump in a dry, protected area.
7. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not starting | No power; tripped breaker; motor issue | Check power supply, reset breaker, contact support if motor is faulty. |
| Low water flow | Clogged skimmer/pump basket; dirty filter sand; air leak | Clean baskets, backwash filter, check all connections for air leaks. |
| Water not clearing | Insufficient filtration time; dirty filter sand; chemical imbalance | Increase filtration time, backwash/rinse filter, test and adjust pool chemistry. |
| Leaks at connections | Loose clamps/fittings; worn O-rings | Tighten clamps/fittings, inspect and replace O-rings if necessary. |
