I just ordered a water tank replacement (part# 4838JA2002B) and was looking for installation instructions.
Answer Hello Ray,
There are not install instructions available to send but to replace the water tank on unit here is what you will need to do. Open left refrigerator door. Take out the lower shelf on the door and remove phillips head screw. Remove the cover over the water tank and valve. Remove the upper left hinge cover. Pull unit out and remove the cover over the single 1/4" line. Making sure that water is shut off disconnect the 1/4" water tube. You will then pull the tube out of the opening on the top of the cabinet. Once this is pulled out remove the spring that goes over it. You will then disconnect the water tank inside the refrigerator door and pull the tubing out of the door for the tank. Once removed you will slide the new tube up through the door. You may have to lift hinge out to get through the top of door. Reinstall in reverse.
