3. Product Overview and Components
Your Intex pool system combines a powerful sand filter pump with a Krystal Clear saltwater system to provide comprehensive pool water treatment.
An overview of the Intex Krystal Clear Sand Filter Pump and Saltwater System, showing both units connected.
3.1 Sand Filter Pump (Model SX2800)
The sand filter pump is the primary filtration unit, using specialized filter sand to trap debris and impurities from the pool water. It features a multi-port valve for various operational modes.

4. Setup and Installation
Follow these steps for proper setup of your Intex Sand Filter Pump and Saltwater System. Ensure your pool is filled to the recommended level before beginning.
- Placement: Position the sand filter pump and saltwater system on a firm, level surface, at least 2 feet (0.6 meters) away from the pool wall. Ensure the location is dry and protected from direct sunlight and extreme weather.
- Sand Filling: Remove the multi-port valve from the filter tank. Place the standpipe over the bottom center outlet. Carefully pour the correct amount of #20 silica sand (77 lb / 35 kg) into the filter tank. Ensure no sand enters the standpipe.
- Multi-Port Valve Installation: Clean the rim of the filter tank. Carefully place the multi-port valve onto the filter tank, ensuring it is properly seated and aligned. Secure it with the clamp or flange provided.
- Hose Connections: Connect the hoses from the pool's inlet and outlet fittings to the corresponding ports on the sand filter pump. Connect the sand filter pump to the saltwater system using the provided hoses. Ensure all connections are tight to prevent leaks.
- Electrical Connection: Connect the power cord to a properly grounded 120 Volt GFCI (Ground Fault Circuit Interrupter) protected electrical outlet. Do not use extension cords.
- Initial Priming: Before starting, ensure the pump is primed by allowing water to flow into the pump housing. Refer to the detailed priming instructions in the full manual.

5. Operating Instructions
5.1 Sand Filter Pump Operation (6-Function Control)
The multi-port valve on the sand filter pump allows for various operational modes:
- FILTER: Normal filtering mode. Water is pumped through the sand bed, filtered, and returned to the pool.
- BACKWASH: Used for cleaning the sand bed. Water flows in reverse through the filter, flushing trapped debris out through the waste port. Perform when pressure gauge reads high or flow is reduced.
- RINSE: Used after backwashing to settle the sand bed and flush out any remaining dirty water from the valve.
- RECIRCULATE: Circulates water through the pump and back to the pool, bypassing the filter. Useful for distributing chemicals without filtering.
- DRAIN: Drains water directly from the pool through the waste port, bypassing the filter.
- CLOSED: Shuts off all flow to the filter and pump. Use only when performing maintenance or when the pump is off.
Important: Always turn off the pump before changing the multi-port valve position.
5.2 Saltwater System Operation
The Krystal Clear Saltwater System generates natural chlorine from salt added to your pool water. It includes a built-in 24-hour timer for automated operation.
- Add Salt: Add pure, non-iodized pool salt directly to your pool water. Refer to the saltwater system manual for the correct amount based on your pool volume. Allow salt to dissolve completely before operating the system.
- Power On: Ensure the sand filter pump is running. Turn on the saltwater system.
- Set Timer: Use the control panel to set the desired operating hours for chlorine generation. The built-in timer allows for automatic daily cycles, reducing manual intervention.
- Monitor Salt Level: The system will indicate if the salt level is too low or too high. Adjust as necessary by adding more salt or partially draining and refilling the pool.
The saltwater system requires a compatible pump with a flow rate between 700 and 3,200 GPH for optimal performance.
6. Maintenance
Regular maintenance ensures the efficiency and longevity of your Intex pool system.
- Strainer Basket Cleaning: The sand filter pump includes a strainer basket that collects larger debris before it reaches the pump impeller. Regularly check and clean this basket to maintain optimal flow and prevent damage to the pump.
- Sand Replacement: Filter sand typically needs replacement every 5 years, depending on usage and water quality. Refer to the manual for detailed instructions on sand replacement.
- Backwashing and Rinsing: Perform backwashing and rinsing cycles regularly, especially when the pressure gauge on the sand filter pump indicates a high reading (usually 5-10 PSI above the clean operating pressure) or when water flow to the pool decreases.
- Saltwater Cell Cleaning: Periodically inspect and clean the electrolytic cell of the saltwater system to remove any scale buildup. Follow the descaling procedure outlined in the saltwater system manual.
- Winterization: Before freezing temperatures, properly drain and store both the sand filter pump and saltwater system. Refer to the winterization section in your full manual for detailed steps.
