Setup and Installation

Installation of the Intex Sand Filter Pump is designed to be straightforward. Partial assembly of the multi-port valve to the sand tank is required. Ensure all connections are secure to prevent leaks.

1. Place the pump on a firm, level surface near your pool.
2. Assemble the multi-port valve onto the sand tank according to the detailed instructions in the user manual.
3. Connect the two 1.5-inch (38mm) connector hoses from the pump to your pool's inlet and outlet fittings. Ensure hose clamps are tightened securely.
4. Fill the sand tank with the recommended amount of #20 silica sand (not included). Refer to specifications for exact capacity.
5. Ensure all valves are in the correct position for initial startup (usually "Backwash" for initial rinse).
6. Plug the pump into a grounded electrical outlet.

Operating the Pump

The multi-port valve on top of the sand filter tank allows you to select different operating modes. The digital control panel enables easy scheduling.

Multi-Port Valve Functions:

• FILTRATION: Standard operating mode for filtering pool water.
• CIRCULATION: Circulates water without filtering (useful for chemical distribution).
• BACKWASH: Reverses water flow to clean the sand filter.
• DRAIN: Drains water from the pool.
• RINSE: Used after backwash to settle the sand.
• CLOSED: Shuts off all water flow to the filter.

Digital Timer:

The built-in 24-hour timer allows you to set automatic operating cycles from 2 to 12 hours. This feature ensures consistent filtration and reduces manual intervention.

Hydro Aeration Technology:

This patented technology injects air into the water, improving circulation and filtration. Benefits include:

• Improved circulation and filtration.
• Enhanced water clarity.
• Increased negative ions for improved air freshness around the pool.

Maintenance

Regular maintenance ensures optimal performance and longevity of your sand filter pump.

Backwashing the Filter:

Backwashing is essential to clean the sand filter. Perform backwash when the pressure gauge reading is 3-5 PSI above the starting clean pressure, or when water flow significantly decreases.

1. Turn off the pump.
2. Rotate the multi-port valve to the "BACKWASH" position.
3. Turn on the pump and run until the water in the sight glass (usually clear) runs clear (typically 1-2 minutes).
4. Turn off the pump.
5. Rotate the multi-port valve to the "RINSE" position.
6. Turn on the pump and run for 30-60 seconds to settle the sand.
7. Turn off the pump.
8. Rotate the multi-port valve back to the "FILTRATION" position.
9. Turn on the pump for normal operation.

Figure 8: The pressure gauge indicates when backwashing is needed (typically when the needle moves into the yellow or red zone).

Strainer Basket Cleaning:

Periodically check and clean the strainer basket located on the pump unit to remove debris and ensure proper water flow.

1. Turn off the pump and close any necessary valves to prevent water flow.
2. Unscrew the strainer basket cover.
3. Remove the basket and empty any collected debris.
4. Rinse the basket thoroughly with water.
5. Replace the basket and secure the cover, ensuring a tight seal.

Sand Replacement:

The filter sand typically needs to be replaced every 2-5 years, depending on usage and water quality. Refer to the user manual for detailed instructions on sand replacement.

Troubleshooting

If you encounter issues with your sand filter pump, try the following common troubleshooting steps:

• Low Water Flow: Check strainer basket for debris, ensure hoses are not kinked, verify multi-port valve is in "FILTRATION" mode, and check pressure gauge for high readings indicating a need for backwash.
• Cloudy Water: Ensure proper chemical balance in the pool, check if the pump is running long enough, and perform backwash if needed.
• Pump Not Starting: Verify power connection, check GFCI outlet, and ensure the timer is set correctly.
• Leaks: Inspect all hose connections and O-rings for proper seating and tightness.
