Emerson Garbage Disposal Installation

Roll a clump of plumber's putty in your hands into a long, cylindrical shape about 1/2 inch thick.

Place the putty around the base of the sink flange, directly underneath the lip of the flange. This is the gasket that fits inside the drain hole in the sink.

Insert the flange into the sink and press down on it.

Go underneath the sink and slide the fiber gasket, backup flange and mounting ring onto the part of the flange that extends beneath the sink. Place a thick rubber band around the flange to temporarily hold the fiber gasket, backup flange and mounting ring in place on the flange.

Place a heavy object in the bottom of the sink on top of the flange to help form a tight seal.

Remove the rubber band from around the flange, and slide the snap ring into the notch around the bottom of the flange beneath the sink. Rotate the mounting ring until the screws on the mounting ring line up with the holes in the backup flange, then turn the screws into the backup flange to tighten the seal.

Knock out the dishwasher inlet plug by tapping a screwdriver on the plug with a hammer, then remove the plug from the garbage disposal. The inlet plug is the smaller of the two protrusions on the side of the garbage disposal and is located along the top edge of the garbage disposal unit. (Skip this step if you don't have a dishwasher.)

Remove the electrical cover plate on the bottom of the disposal and pull the wires out, but do not touch the cardboard shield.

Insert a cable connector through the access hole on the bottom of the disposal, then slide the electrical cable through it and into the disposal. Tighten the cable connector.

Connect the wiring from the garbage disposal to the wires leading from your home's main electrical box. Remove about 1/2 inch of insulation from the garbage disposal wires (if needed), then twist them to the wires leading from the electrical box with plastic connector caps. Connect the white wires together, connect the black wires together and wrap the green grounding wire to the grounding screw, then tighten the screw.

Push the wires into the garbage disposal (without moving the cardboard shield), and replace the cover plate.

Connect a tube to the Anti-Vibration Tailpipe Mount on the side of the disposal with a spring-type hose clamp. Emerson provides two tubes for this, one straight and one with a 90-degree elbow; use the one that fits best for your sink.

Hang the disposal on the bottom of the sink flange by lining up the mounting tabs, then turning the mounting ring until all three tabs lock into place.

Connect the plumbing to the garbage disposal unit. Turn the disposal unit until the discharge tube connected to the Anti-Vibration Tailpipe Mount is lined up with the drain trap (the U-shaped part of the drain pipe), then connect the discharge tube to the drain trap and tighten the nut on the drain trap to secure the fitting. If the discharge tube is too long, cut it to fit; if it's too short, buy an extension tube to fit between the discharge tube and the drain trap.

Insert the sink baffle into the drain hole at the bottom of the sink. Fill the sink with water, then drain it to test the connections for leaks.

Restore power to the disposal at your main electrical box.
