How to change the cartridge in your Jacuzzi J-425
Watch the guide or follow the steps.
- 1Switch the spa off at the isolating switch or switchboard; Jacuzzi says always turn the power off before cleaning the filters.
- 2Lift the filter cover up to reach the cartridges, and unclip the ProClarity debris bag and empty it.
- 3Turn each cartridge handle anticlockwise to unscrew it from the wall fitting and lift it out. Filter 1 (ProClarity) is the one nearer the front of the spa.
- 4Pull the filter pin to separate the ProClarity cartridge from its canister, then unscrew the cartridge anticlockwise. Fit a new depth filter (6473-161J) every 3 months; never wash it.
- 5Rinse the pleated cartridges from the top down with a hose, or fit new ones. Reassemble the canister with the pin.
- 6Hold the cartridges under water to let the air out, screw them back in clockwise without over-tightening, refit the debris bag and cover, and turn the power back on.
