Here is the PDF Manual To Install Garbage Disposal at home.
Step 1: Turn OFF the Circuit Breaker:
The first step of any job that involves dealing with electronics should always be turning off the circuit breaker. Disconnect the power cord from your old waste disposal if you are replacing it.
Always remember to do this before you start dealing with electronic devices as negligence towards this step can lead to fatal consequences.
Step 2: Disconnect the Previous Kitchen Waste Disposal Unit:
Position a bucket under the sink and disconnect the drainpipes attached to the previous disposal. Then disconnect the disposal from flange assembly. Remove the sink strainer and flange and scrape off any excess putty.
Step 3: Secure the Flange:
Before installing the new disposal unit, make sure to firmly secure the fitting that will ensure proper working of disposal unit by holding it under the sink. For this, first put the plumber’s putty around the sink hole at least ½ inch thick.
Press the drain flange firmly and cover it with a towel. Now put the waste disposal unit or any other heavy object on top so that the flange remains fixed.
Step 4: Position the Mounting Assembly:
On the underside stack up the fiber gasket and mounting ring and slide onto the flange under the sink. Now, install the snap ring into the groove or on the drain fitting by pulling it open and snapping into place.
Step 5: Tighten the Mounting Assembly:
The mounting assembly, which consists of the flange and mounting ring sandwiching the drain needs to be firmly tightened to lock the waste disposal into place.
It has three mounting screws, using a screwdriver tighten them by applying even pressure. Be sure to tighten until extra plumber’s putty oozes out of the drain however, over tightening will remove all the plumber’s putty and drain seal will be broken. Use a rag to remove the excess putty which seeped out during tightening.
Step 6: Remove the Plug:
Now comes the electrical portion of our ‘how to install a garbage disposal’ guide. First and foremost, knock out and remove the drain plug from the inlet on the disposal present at the bottom.
Step 7: Make Wire Connections:
Now, connect the wires from the disposal to the power cord wires appropriately; white with white, black with black and the green ground wire to the green ground wire. Now replace the cover plate of the inlet after tucking the connected wires into disposal electrical box.
Additional Step: If your dishwasher is to be connected with the garbage disposal unit, then first remove the plug from the disposal inlet present at the top using a hammer and screwdrivers. Now, remove the knockout plug inside the dishwasher nipple on the disposal unit.
Step 8: Mount the Disposal:
Mount the garbage disposal to the system by aligning the top collar on the disposal with mounting assembly of sink drain. For this purpose, rotate the top collar so that the mounting ears at the bottom of mounting assembly engage with the disposal.
Step 9: Make Connections with the Drain:
To connect the drain, insert the gasket in the discharge outlet and connect the discharge tube with the sink drain waste trap by rotating the disposal so that the two are aligned.
If your dishwasher has to be connected with disposal then attach the dishwasher hose with disposal nipple. Make sure to properly connect all these pipes because the consequences of carelessness can be quite messy.
Step 10: Firmly Secure the Disposal:
Lock the disposal into place by tightening the rotating cam collar on the disposal with the mounting assembly.
You can either use screwdrivers or wrenches for this step. A clear ‘click’ can be heard which indicates that your disposal is firmly locked into place.
Step 11: Test your Piece of Work:
Test whether you have correctly installed the garbage disposal or not. Turn On the circuit breaker and check your work by first running water through it. If there are any leaks, that means you haven’t properly connected the pipes, find out the location of leaks and fix them.
Afterwards, throw some organic waste like fruits and vegetable peels into the disposer to check the functioning of its motor. If all is well, then take a moment to appreciate how well you have learned how to install a garbage disposal and relish on your success.
