4. Installation

4.1. Pre-Installation Steps

1. Disconnect Power: Turn off all power to the pump at the main circuit breaker. Verify power is off using a voltage tester.
2. Drain System: Close all necessary valves to isolate the pump and drain any water from the pump and associated plumbing.
3. Gather Tools: Prepare necessary tools, which may include screwdrivers, wrenches, pliers, and a seal lubricant.
4. Inspect Old Housing: Carefully examine the existing pump housing to understand how it is assembled and identify all components that need to be transferred or replaced.

4.2. Housing Replacement Procedure

Follow these steps to replace the pump housing:

1. Remove Old Housing: Disconnect the plumbing connections to the pump housing. Carefully unbolt or unscrew the old housing from the motor assembly.
2. Transfer Components: Remove and carefully retain the inlet/outlet connection seals, the 6 screws, and threaded blocks from the old housing. These components are typically reused.
3. Clean and Inspect: Clean any debris from the motor face and inspect the impeller and diffuser for damage. Replace any worn or damaged parts.
4. Install New Seals: Apply a silicone-based lubricant to new O-rings and seals (especially the housing and diffuser O-rings from a repair kit like SPXHKIT100) and place them correctly into the new housing.
5. Position New Housing: Carefully align the new SPX3200A housing with the motor assembly, ensuring the impeller and diffuser fit correctly.
6. Secure Housing: Reinsert and tighten the 6 screws and threaded blocks to secure the new housing to the motor. Ensure even tightening to prevent stress cracks.
7. Reconnect Plumbing: Reattach the plumbing connections to the inlet and outlet ports of the new housing. Ensure all connections are tight to prevent leaks.
8. Prime and Test: Once installation is complete, open all valves, prime the pump, and restore power. Carefully check for any leaks around the housing and plumbing connections.

5. Operation

The SPX3200A is a pump housing and does not have independent operational controls. Its function is integral to the overall operation of the pool pump. Once installed, the pump housing facilitates the flow of water through the pump's wet end. Refer to your specific Hayward TriStar or EcoStar pump's instruction manual for detailed operating procedures.

6. Maintenance

Regular maintenance of the pump housing ensures optimal performance and extends its lifespan:

• Regular Inspection: Periodically inspect the housing for any signs of cracks, wear, or damage, especially around connection points and mounting areas.
• Seal Integrity: Check the O-rings and seals for dryness, cracking, or flattening. Replace them as needed to prevent leaks.
• Strainer Basket: Ensure the strainer basket inside the housing is clean and free of debris. A clogged basket can restrict flow and stress the pump.
• Winterization: During winterization, ensure the housing is completely drained to prevent freezing and potential cracking.
