To replace the water filter:

  1. Open the refrigerator door.
  2. At the top of the interior above the control panel, pull out on the bottom edge of the water filter access door panel with "Sub-Zero" printed on it, and rotate upward.
    • It may be necessary to remove the right or left side trim panel to rotate the water filter panel.
  3. Rotate the old filter counterclockwise one-quarter turn, and then pull it out.
    • It is normal for a small amount of water to drip when the filter is removed.
    • Wipe up the water with a paper towel or cloth.
  4. Remove the new filter from packaging and remove the plastic cap.
  5. Insert the new filter into the manifold and turn clockwise.
  6. Once the new filter has been installed, follow instructions on the control panel.
  7. After installation of a new filter cartridge, allow 24 hours to pass. Then discard the first full bucket of ice to help clean the water system and clear air from the line.
  8. For dispenser models, the water line is typically purged before connecting to the unit. However, the first several glasses of water should be discarded after replacing the filter.
