Before installing, check local plumbing codes. AFW is not responsible for anything resulting from improper installation or installation that does not follow local codes.

Each installation of a whole house filter will be different, depending on the system ordered and the application it is being used for. Read through entire instructions before beginning. These instructions provide a guideline on how to install your new system. If you do not have the proper tools or abilities, a local plumber should be contacted to install the system for you.

  1. Shut off water supply to house
  2. Locate the water line point of entry into the house
  3. Determine installation location. Ensure plenty of room for access for later filter changes, and locate in a position where it can be mounted if possible. This will provide extra support to the system
  4. If the system is completely assembled, remove the canister(s) from the bracket and lid assembly. This will make installation easier
  5. If lid(s) are not mounted to the bracket use screws provided to attach the bracket to the housing lid(s) so that it matches your plumbing setup. (I.E. If your plumbing flows left to right, attach the lid(s) to the bracket so that the inlet is on the left side, if your plumbing flows right to left, attach the lid(s) so the inlet in on the right side.)
  6. Cut out the required amount of pipe to install the filter system. Some people prefer to plumb in a bypass loop as well
  7. Wrap the supplied hex nipple (white fitting with threads on both sides) with teflon tape or pipe seal
  8. Using the prepared hex nipple, connect the shut off valve to the inlet side of the filter
  9. Using the appropriate connections, connect to the inlet and outlet of the water filter to your plumbing. Make sure all connections are sealed against leaks
  10. Check the O-ring(s) in the top groove of the filter housing. Make sure there are no kinks or nicks. If everything looks good, lubricate the O-rings with a silicon based lubricant (vegetable oil may be used as a substitute, DO NOT use Vaseline)
  11. Filter order will depend upon the number of filters on the system. A general rule is that the sediment filter will go first, a carbon filter will go last, and any specialty filters will go in the middle. Ensure all housings are tightened down.
  12. Ensure the shut off valve on the system is closed, and slowly open the main water line. Ensure there are no leaks from the shut off valve
  13. If no leaks are present, open the shut off valve and ensure there are no leaks anywhere else on the system
  14. If any leaks are discovered, shut the water off immediately and correct the problem

Filter life on the system depends on water usage and water quality, as well as filter configuration and contaminate levels, but generally you will want to change your filters every 6 months. If you notice reduced pressure in your house it is a good bet the filters are clogged and need changed. If you have a lot of dirt in the water, the sediment filter may need changed more often than other filters.
