How To Install a Garbage Disposal

Continued from page 4

Step 4: Knock out the Dishwasher Plug (continued)

Please refer to the instructions included with your disposal for the proper method of extraction. However, in several models, it is simply knocked out using a screwdriver and a mallet. Remove any pieces knocked out so that they don't jam or damage the disposal. Follow the instructions for your model.

Step 5: Connect the Wiring

Caution: Before proceeding with this step, shut off the power at the fuse box or breaker panel to avoid injury.

There are two ways your disposal may be wired; with an electrical cord or by direct wiring to your home's electrical system. If you are replacing a disposal, then your task is simple, connect the new disposal in the same way as the old.

If your old wiring is not grounded or you are adding a disposer for the first time and there is no electrical service under the sink, then now is where you may need to consult a professional electrician. While adding electrical service or upgrading to grounded wiring may be within the scope of your abilities as a do-it-yourselfer, it is beyond the scope of this article.

Your disposal probably came without an electrical cord. You can disconnect the cord from the old unit. If it is in good condition go ahead and use it on the new disposal. Otherwise, you will need to purchase one.

If your old disposal was direct wired, then it is a simple task to wire up the new unit to the three terminals (hot, neutral and ground).
