Installing the ice maker
- Remove the plug from the inside of the freezer compartment with a putty knife or flat blade screwdriver.

- Peel off the label covering the ice maker hole on the back of the refrigerator, then remove the foam from the hole with the needle-nose pliers.

- Push the water inlet tube into the small hole on the back of the refrigerator. Rotate while inserting the tube until the flat surface of the inlet tube is tight against the back of the refrigerator.

- Secure the water inlet tube to the back of the refrigerator with two of the provided chrome head screws with washers.

- Insert the two ice maker mounting screws (the screws with white heads) into the holes in the freezer wall. Turn each screw clockwise five times. Do not tighten the screws completely.

- Use needle-nose pliers or a flat-blade screwdriver to remove the terminal cover located at the top of the freezer by first pulling down one side of the cover, then pulling down the other side.

- With the ice maker in one hand, plug the wiring harness connector into the terminal located at the top of the freezer panel. The connector only fits one way.

- Make sure that the water inlet tube is sitting inside the fill cup, then tighten the screws.

- The ice maker is level when the gap between the freezer wall and the ice maker is the same at the top and bottom.

- Reinstall the freezer shelf and set the ice storage bin on the shelf.

- Locate the pre-punched holes at the bottom right corner of the back panel of the refrigerator.

- Connect the wiring harness to the water valve, making sure that the connection is tight.

- Grasp the other end of the plastic tube and push it firmly into the quick-connection on the valve until it bottoms out.

- Clean the back of the cabinet with a commercial household cleaner, ammonia, or alcohol before applying the clamps.
Connecting the Ice Maker to the Water Supply
- Disconnect the refrigerator from the electric wall outlet.
- Remove the parts in the water line kit that you purchased for this purpose.
- Connect the end of the water supply line to the household cold water line behind the refrigerator. Choose a location for the valve that is easy to access.
- We recommend that you connect it to the side of a vertical water pipe.
- Remove any burrs resulting from drilling the hole.
- Take care not to allow water to drain into the drill. Failure to drill a ¼” hole may result in reduced ice production or smaller cubes.
- Fasten the shutoff valve to the cold water pipe with the pipe clamp, then tighten the pipe clamp screws until the sealing washer begins to swell.
- Do not over-tighten, or you may crush the tubing.
- Make sure the tubing is fully inserted into the valve.
- Unscrew the plastic cap from the water inlet valve and discard it.

- Slide a brass compression nut, then a ferrule (sleeve), onto the water supply line.

- Push the end of the tubing into the water inlet Insignia NS-IMK20WH7 Ice Maker Kit valve as far as it will go, or ¼-inch, then secure the water supply line to the back panel of your refrigerator with a steel clamp and screw at the location shown on the illustration.
- Coil the excess water supply line (about 2-½ turns) behind the refrigerator and arrange the coils so they do not vibrate or wear against any other surface.
- Turn on the water supply at the shutoff valve and tighten any connections that leak.
- Reconnect the refrigerator to the electric wall outlet.
- To turn on the ice maker, lower the wire signal arm.
- Slide the ferrule (sleeve) into the valve inlet and finger-tighten the compression nut onto the valve.
Using your Automatic Ice Maker
- Remember that water quality determines the quality of ice.
- The ice maker should not be connected to softened water. If the water softener has problems, chemical substances can damage the ice maker.
- To turn off the ice maker, raise the wire signal arm until it locks in the “up” off position.
- When the ice storage bin is full, the wire signal arm will hit the ice cubes, and the ice maker will automatically shut down.

- If you store ice cubes for too long, they may produce a peculiar smell.
- To eliminate the smell, empty the ice storage bin, wash it out, then replace it.
- The ice maker will produce more ice cubes. Shake the ice storage bin from time to time to ensure that the ice cubes separate from each other.
Maintaining your ice maker
Use mild detergent in warm water to clean the ice storage box, then rinse and dry it. Turn off the ice maker when you clean your refrigerator or plan to be away for a short period. If you are going away for an extended period, turn off the water supply valve.

FAQs
Q: Is this kit compatible with any refrigerator?
Ans: No. Only a few Insignia top-freezer refrigerators that are ice maker-ready—that is, already equipped with ports and brackets—are compatible with the NS-IMK20WH7. To verify compatibility, see the user manual or the model number of your refrigerator.
Q: Does this ice maker need a water hookup?
Ans: Indeed. You could want a longer water line or expert installation if your refrigerator is not close to a water supply.
Q: How much ice does the kit produce daily?
Ans: Depending on usage and freezer temperature, the NS-IMK20WH7 can generate up to 3 to 4 pounds (1.3 to 1.8 kg) of crescent-shaped ice every day.
Where does the ice go after it’s made?
Ans: Underneath the freezer’s ice maker, the ice falls straight into the attached ice bin.
Can I use this kit with a bottom-freezer or side-by-side fridge?
Ans: No. Unless otherwise noted, this kit is incompatible with side-by-side or bottom-freezer versions.
Do I need a separate water filter?
Ans: A water filter is not included in the kit. Installing an inline water filter is advised if your home has sediment problems or hard water in order to extend the life of the ice maker and enhance the quality of the ice.
