Guard the heart of your high-flow pump system with the Pentair Basket, model 400007Z, precision-molded for WhisperfloXF and IntellifloXF pump platforms. This oversized strainer basket intercepts leaves, twigs, and fine particulate before they ever reach the impeller, preserving hydraulic efficiency and preventing premature wear. Formed from a rigid, UV-stabilized material, the basket resists warping, cracking, and chemical degradation even after extended exposure to treated pool water. A keyed alignment rib ensures correct seating every time, so water flows cleanly through the volute without bypass.

Key Benefits

• Upstream Debris Barrier: Captures contaminants ahead of the impeller and volute, preventing blockages that reduce flow rates and strain motor bearings.
• Extended Equipment Lifespan: By filtering out abrasive particles and organic matter, the basket reduces impeller erosion and helps your pump deliver full performance for more seasons.
• Rugged Material Composition: Manufactured from a UV-stabilized, chemically inert polymer that maintains structural integrity under prolonged chlorine and saltwater exposure.
• Integral Alignment Feature: A molded locating rib mates with the volute notch, guaranteeing correct orientation and eliminating the risk of misseating during reassembly.
• Consistent Hydraulic Efficiency: Properly captured debris and a secure basket seat work together to maintain designed flow characteristics, supporting optimal filtration and circulation.

Installation & Operation Tips

1. Press the Start/Stop button on the pump, then shut off the circuit breaker. Disconnect the communication cable from the pump. 2. Release all system pressure. 3. Rotate the lid and locking ring counter-clockwise, then lift them off the pump housing. 4. Pull out the basket, clear away trapped debris, and rinse thoroughly. If the basket shows any cracks, install a new one. 5. Lower the basket back into the housing, lining up the alignment rib on the basket with the corresponding notch inside the volute. 6. Fill the strainer pot and volute with water up to the level of the inlet port. 7. Wipe down the lid, locking ring, O-ring, and the sealing rim of the strainer pot.

Note: Keeping the lid O-ring clean and properly lubricated is critical for maintaining a reliable seal. 8. Place the locking ring and lid onto the pot, confirming the O-ring sits in its groove correctly. Turn the assembly clockwise until the locking ring handles rest in a horizontal position. Note: Verify that the side of the lid/locking ring stamped "Front" faces the front of the pump. 9. Restore power at the circuit breaker and reconnect the communication cable. 10. Open the manual air relief valve on top of the filter and stand well clear of the filter assembly. 11. Allow all trapped air to escape, then start the pump. 12. Continue bleeding air from the filter until a solid, steady stream of water exits the air relief valve, then close the valve.
