CLEANING YOUR SINK'S DRAIN LINE

We recommend cleaning the line before connecting your new disposer. You can do the job yourself with a drain
auger. Remove the drain trap and, using the auger, clean out the horizontal drain pipe that runs from the trap to the
main waste pipe. Make certain that the auger removes the hardened material that forms at the intersection of the
horizontal pipe and the main waste pipe.

ELECTRICAL SUPPLY

First, remove the fuse or open the circuit
breaker on the circuit you plan to use for your
disposer. Use a separate 15 or 20 amp, 120
volt circuit for the disposer. If you are
replacing a unit, skip to step 4. Next, use 15­20 amp, 120 volt cable to make a connection
from the junction box to the on-off switch.

NOTE: See 10&11 for final electrical connections.

Install a junction box and switch. (Obtain 1/2
H.P., 15-20 amp rated on-off switch and
electrical wiring locally.) Position the switch in
any convenient location, and connect to
junction box. All wiring must comply with
local electrical codes. 14 gauge size wire is the
smallest permissible for use with a 15 amp
circuit, and 12 gauge is the smallest
permissable for use with a 20 amp circuit.

REPLACING AN OLD DISPOSER

FIRST, TURN OFF ELECTRICAL POWER at the service panel (fuse box or circuit breaker box). If the mounting is the same as your new
disposer's mounting, you can use the existing mounting. Follow instructions A, B, D and E, Step 4, then go on to Step 6.

IF YOUR OLD DISPOSER HAS A DIFFERENT MOUNTING THAN
YOUR NEW ONE, GO ON TO INSTRUCTION C.
If your old disposer has the same mounting as your new one, insert the
end of your "wrenchette" or screwdriver into the right side of one of the
disposer mounting ring lugs at the top of the disposer. Then, turn the
"wrenchette" or screwdriver to the left (counter-clockwise) until the lug
lines up with one of the sink mounting assembly screws.

Use a pipe wrench to
disconnect the drain line
where it attaches to the
disposer discharge tube.

CAUTION: Be sure to hold the disposer with one hand while performing this step or
it may fall when the mounting ring is disconnected from the sink mounting assembly.

GO TO INSTRUCTION D.

If your old disposer has a different
mounting than your new one, use a pliers
or adjustable wrench to remove the nuts
on the mounting ring. Then remove old
disposer. (Some disposers have to be
removed by taking off a clamp or by
twisting the disposer to remove it from its
mounting. Easy to figure out.)

Once the disposer is off, turn
it upside down and remove the
electrical plate.

INSTALLING A FIRST-TIME DISPOSER

Use a wrench to loosen the nut at
the top of the "P"-trap.

The nut should be loosened
enough that you can spin it off by
hand.

Next, remove the nut at the top of
the sink strainer and remove the
extension pipe.

Now, push the strainer assembly
up through the sink hole and
remove it.

Now, remove the large-diameter nut at the base of the strainer by placing
the tip of your screwdriver on the edge of the nut. (There are usually
ridges to hold your screwdriver.)
