RE-1 Replacement Elements for the AF-1
Replacing the filter element is easy. Locate the tabs on the front face of the filter body. Gently pull the front half of the filter body away from the back half (the back half should remain attached to the refrigerator wall). Push the old foam element out and discard. Insert the new foam and reattach the front to the back of the filter body. Press the unit firmly in place. Change the filter element every three to six months as needed.
