Protect the ring by snapping the round clip springtime or break ring into the groove on the flange tailpiece.

3. Tighten Up the Installing Ring Setting Up
Tighten down the installing setting up by tightening the 3 mounting screws, tightening each a little at a time to progressively apply also pressure.

9. Look for Leakages and Correct Procedure.
Activate the water and also run it via the disposal to inspect all connections for leaks. If there are leakages, tighten any kind of loosened drain links. Plug in the disposal to the wall electrical outlet and make certain the circuit power is activated.
