To allow easy access to overload reset button, the

disposer plumbing should be connected with the

electrical control box facing the operator.

When connecting the drain line, place the “P-trap” as

close to the disposer outlet flange as possible.  Do not

connect the drain line to a grease trap, interceptor, or

drum trap.

All horizontal runs should be as short as possible, with

a minimum fall of 1/4 inch per foot.
