Complete the Installation
Connect the electrical wires, splicing white to white and black to black, then secure the connections with wire nuts. Connect the ground wire to the green screw on the disposal, and replace the cover plate.
Hang the disposal by twisting it into place on the mounting nut. Rotate the disposal until it is properly aligned, then attach the drain arm and dishwasher drainpipe. Run water through the disposal for a few minutes to check for leaks. Then turn the power back on.
Note: The disposal may be heavy, so you might want to build a support base to hold it up.
