Key Features
- Hydro Aeration Technology: Enhances water circulation and filtration, improves water clarity, and increases negative ions at the water surface for improved air quality.
- Easy Installation: Simple setup requiring only hose connections and power plug-in.
- 2100 GPH Pump Flow Rate: Provides a water flow rate of 2,100 gallons per hour (7,949 lph) at the pump, with a system flow rate of 1,600 gph (6,056 lph) in the pool. Suitable for Intex pools up to 12,800 gallons.
- Built-in 24-Hour Timer: Features pre-set cycles from 2 to 12 hours for automatic operation.
- Saltwater System Integration: Utilizes the same process as in-ground swimming pools to maintain clear water with reduced maintenance.
- Advanced Filtering System: Connects directly to the filter pump, automatically generating chlorine from added salt. Includes an intuitive control panel display.

Setup Instructions
- Placement: Position the sand filter pump and saltwater system on a stable, level surface near your above-ground pool. Ensure adequate space for operation and maintenance.
- Hose Connections: Connect the hoses from your pool to the appropriate inlets and outlets on the filter pump and saltwater system. Ensure all connections are secure to prevent leaks.
- Power Connection: Plug the unit into a grounded 120-volt electrical outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI).
- Sand Filling: Refer to the specific instructions for filling the sand filter tank with the recommended amount and type of filter sand (50 lb (23 kg) #20 Silica).
- Initial Priming: Follow the manufacturer's instructions for priming the pump to ensure proper water flow and prevent airlocks.

Operating Instructions
Sand Filter Pump Operation
The sand filter pump offers 6 functions for comprehensive pool maintenance:
- Filtration: Standard daily operation to filter pool water.
- Circulation: Moves water without filtering, useful for chemical distribution.
- Backwash: Reverses water flow to clean the sand filter.
- Rinse: Settles the sand after backwashing.
- Waste/Drain: Drains water directly from the pool.
- Closed: Shuts off all flow to the filter.
Use the built-in 24-hour timer to set automatic operating cycles (2 to 12 hours) for consistent filtration.
Saltwater System Operation
The Krystal Clear Saltwater System converts salt into natural chlorine for pool sanitation. Add pool-grade salt to your pool water as per the system's guidelines. The intuitive control panel allows you to monitor salt levels and select from 3 self-clean modes (6, 10, or 14-hour cycles) for optimal chlorine generation.

Maintenance
- Sand Replacement: The filter sand typically requires replacement every 5 years, depending on usage and water quality.
- Regular Backwashing: Perform backwashing as needed to clean the sand filter and maintain optimal filtration performance. Monitor the pressure gauge for indications of when backwashing is required (e.g., when pressure rises above normal operating levels).
- Strainer Basket Cleaning: Periodically check and clean the strainer basket in the pump to remove debris and ensure unobstructed water flow.
- Saltwater Cell Cleaning: Follow the saltwater system's instructions for periodic self-cleaning cycles or manual cleaning of the electrolytic cell to prevent mineral buildup.
- Winterization: Properly drain and store the pump and saltwater system during off-season or freezing temperatures to prevent damage.

Troubleshooting
If you encounter issues with your Intex Sand Filter Pump or Saltwater System, consider the following general troubleshooting steps:
- Low Flow/Pressure: Check for clogged strainer baskets, dirty filter sand (requiring backwash or replacement), or kinks in hoses. Ensure the pump is properly primed.
- Water Clarity Issues: Verify proper filtration cycles are set, check chemical balance of the pool water, and ensure the saltwater system is generating sufficient chlorine.
- Saltwater System Errors: Consult the system's control panel display for error codes. Common issues include low salt levels (add salt) or cell cleaning required (run self-clean cycle or manual clean).
- Pump Not Starting: Ensure the unit is securely plugged into a working GFCI outlet. Check the timer settings.
