How do you replace hayward spx1070khr weir assembly?

To replace the Hayward SPX1070KHR weir assembly, first, turn off the pool pump and ensure the system is depressurized. Remove the old weir assembly by gently pulling it out of the skimmer. Align the new weir assembly with the skimmer opening, ensuring it fits securely, and then push it into place. Finally, turn the pump back on and check for proper operation.
