Complete Home Filtration Filter Replacement Guide


This is an example setup, please replace the filters in the same order you took them out.

If you are unsure of the order of your filters please contact the service team on 1300 693 458

  1. Remove the UV protective case by unscrewing the screws on the side of the cover.
  2. Turn the system off by turning the three levers to a horizontal position as shown in the above diagram.
  3. Relieve pressure by pressing any one of the three red pressure relief buttons on top of the housings. There will be a small spray of water and the gauges will show a pressure drop.
  4. Loosen the filter housings using the supplied wrench (pull the wrench to the left to rotate the housings clockwise) and remove all three old filters.
  5. Remove all packaging from the new filters and insert the new filters into cartridges A and B. Leave C empty for now. Make sure filters are properly seated in the housings and that your old rubber grommets are seated in the new filter heads.
  6. Tighten all housings with the wrench until reasonably firm. Do not over-tighten, as this will make future filter changes more difficult.
  7. Turn the system back on by returning levers to a vertical position as shown on the above diagram.
  8. Turn on a downstream outside tap (or an inside non-mixer cold water tap if no outside taps are available). Allow water to run for 5 minutes to flush any trapped air or foreign bodies out of the system.
  9. Repeat steps 2-8, replacing only cartridge C. Ensure filters are properly seated in housings and that any rubber ‘O’ rings are seated in place.
  10. Congratulations! You have now changed your Standard CHF filter set.
