Kenmore 1/2 HP Food Waste Disposer Instructions

Remove the Old Food Waste Disposer

• 1

  Unplug the garbage disposal from the wall outlet. If you cannot unplug it, turn off power at the circuit box.

• 2

  Use an adjustable wrench to loosen the nut that connects the P-trap to the extension pipe. Use a screwdriver to disconnect the screws that connect the discharge tube to the disposer.

• 3

  Put one hand on the bottom of the old disposer while you turn the old disposer to the left. The disposer is heavy, so don't let it fall as it disconnects from the sink.

• 4

  Turn the disposer over to remove the cover on the bottom of it. Unwire the electrical cords only if the unit connects directly to the electrical system.

• 5

  Loosen three screws that hold the mounting ring in place under the sink. Pry off all of the gaskets with the tip of the screwdriver. Push the sink flange up through the sink and discard it. Wipe off any plumber's putty that remains around the sink's hole.

Install the New Unit

• 6

  Hold the mounting ring of the new Kenmore garbage disposer in one hand while you insert a screwdriver into a mounting lug. Twist the mounting assembly counterclockwise to separate it from the mounting ring. Unscrew the three screws. Pry off the snap ring carefully.

• 7

  Roll plumber's putty between your hands to make a 3/4-inch thick rope long enough to encircle the top of the drain. Press the sink flange into the sink hole, centering it on top of the putty. Wipe off any excess putty. Set a weight on the flange to help hold it in place until you complete the next step.

• 8

  Connect the top of the sink flange with the bottom by pushing the fiber gasket and metal backup ring over the sink flange in that order. Push the mounting ring flush against the backup ring. Pop the snap ring in place on the flange next. Use the three screws on the mounting ring to hold all these parts in place. Tighten the screws against the underside of the sink.

• 9

  Place the tip of the screwdriver in the dishwasher knock-out hole. Tap it lightly with a hammer. Remove the plug from inside the disposer. Skip this step if you don't have a dishwasher.

• 10

  Pull off the bottom cover of the new disposer. Run the wires of the disposer's cord through the access hole. Wrap the bare wire around the grounding screw on the bottom of the disposer. Tighten the screw. Connect the white wires of the disposer and electric line with a wire nut. Do the same for the black wires. Replace the bottom plate.

• 11

  Hold the disposal's neck against the sink mount. Align the tabs within the mounting tracks. Turn the disposer to the right to lock all three tabs into position.

• 12

  Slide the metal flange over the disposer's discharge tube. Slip a rubber gasket inside the discharge tube. Fasten the flange into the receptacle on the side of the disposer using the screws in the flange. Pull the P-trap nut up and over the lower end of the discharge tube. Tighten the P-trap nut by hand.

• 13

  Slide a hose clamp over the end of the dishwasher's drain hose. Tighten the screw on the hose clamp to secure the drain hose to the dishwasher inlet on the disposer.

• 14

  Run some water through the sink to ensure there are no leaks. Tighten fittings if you see drips.

• 15

  Plug the disposer into the outlet under the sink or turn the power back on. Run water while you check the disposer's operation.
