Installation Instructions
  1. Select a location for the inline filter that allows for adequate access for easier future filter replacements.
  2. Turn off the water supply to the tubing where the inline filter will be installed.
  3. Remove the existing filter or cut the cold water tubing where the filter will be installed.
  4. Note: Cut tubing square and cleanly. An uneven or rough cut may damage the internal o-ring and cause leaks.
  5. Remove the blue clips on both ends of the inline filter.
  6. Confirm that the water flow matches the flow direction arrow on the cartridge.
  7. Insert the water supply end of the tubing into the quick connect fitting on the end of the filter.
  8. Once the tubing has bottomed in the fitting and cannot be pushed in any further, gently pull back to ensure the tubing is secure.
  9. Slowly turn on the water supply and flush the filter with water into a bucket. Run the water for 5 minutes.
  10. Reinstall the blue clips in the groove on the quick connect fittings on each end of the filter cartridge.
  11. Connect the other appliance end of the tubing to the outlet of the filter. Secure the filter to the back of the appliance or wall using adhesive tape.
  12. Turn on the water and check for leaks. Continue to check for leaks for several days.
  13. Replace your filter cartridge once the media has been exhausted. Exhausted media will have changed in color from green to purple.
