ATTACH UPPER MOUNTING ASSEMBLY TO SINK FLANGE
5
REMOVE EXISTING DISPOSER
6
You may wish to place a weighted object in the sink to hold the sink flange in place. (Place a
towel under object in sink to prevent scratching.) Reference Figure 5-1 for part identification.
1. Working from under sink, slip rubber gasket and pressure plate over sink flange.
2. Holding rubber gasket and backup ring in place, slip upper mounting ring over sink flange
so it seats against pressure plate.
3. With rubber gasket, pressure plate, and upper mounting ring tight to sink bottom, slide
snap ring onto sink flange until it pops into groove on flange*.
4. Tighten three mounting screws up to sink until mounting assembly is seated tightly and
evenly against sink.
*Placing a thick, wide rubber band around the sink flange (above the snap ring groove) may
help hold parts in place while installing snap ring. (Remember to remove rubber band after
snap ring is installed.)
WARNING
Electric Shock
•Turn off electrical power at fuse box or circuit breaker before re-
moving electrical cover plate.
•Disposer must be grounded. Improper connection can result in
electric shock.
CAUTION
•Do not position your head or body under disposer; unit could fall during removal
or installation.
1. Turn off electrical power at fuse box or circuit breaker.
2. Disconnect drain trap from disposer waste discharge tube with adjustable pliers
(see Fig. 6-1). (Disconnect dishwasher drain connection, if required.)
3. Support disposer with one hand and insert end of wrenchette or screwdriver into
right side of one mounting lug on lower mounting ring (see Figure 6-2). Lift dis-
poser slightly and loosen lower mounting ring by pushing or pulling wrenchette or
screwdriver to left until disposer is free from mounting assembly. (Disposer may be
heavy - provide support.)
4. With electrical supply turned off, turn disposer upside down and remove electrical
cover plate (see Figure 6-3). Loosen green ground screw and remove wire nuts
(see Figure 6-4). Disconnect disposer wires from electrical supply wires. Loosen
screw(s) on electrical clamp connector and remove wires from disposer.
•If the new disposer mounting is the same as old one, remove mounting assembly
from disposer (Instruction 3) and go to Instruction 7.
•If the new disposer mounting is different from the old one (or you wish to replace
the old sink flange) you must complete Steps 5 - 6 (below), and Instructions 2 - 5,
then continue with Instruction 7.
5. Loosen three mounting screws, pry snap ring off with screwdriver, and remove old
mounting assembly (see Figure 6-5). (Some mounting assembly removal requires
additional tools.)
6. Push old sink flange up through sink hole (see Figure 6-6). Use screwdriver or putty
knife to scrape all old compound and other material from edge of sink hole.
If replacing an existing disposer, go to Instruction 6. If this is a first time installation,
skip ahead to Instruction 7.

CLEAN SINK DRAIN LINE
7
Failure to clean sink drain line may result in drain line blockage.
1. Remove P-trap.
2. With drain auger, clear all hardened waste material in horizontal drain line.
PREPARE DISHWASHER DRAIN CONNECTION (IF APPLICABLE)
8
CONNECT DISPOSER TO ELECTRICAL SUPPLY
9
The knockout drain plug should only be removed if you are connecting a built-in
dishwasher to the disposer. NOTE: If the dishwasher connection is made without
removing the plug, the dishwasher may overflow. (Connections must comply with local
plumbing codes.)
Remove Knockout Plug
1. Lay disposer on its side and insert screwdriver into dishwasher inlet so tip rests on
outer edge of knockout plug.
2. Tap end of screwdriver handle with hammer until molded plug breaks loose (see Fig-
ure 8-1).
3. REMOVE LOOSE KNOCKOUT PLUG FROM INSIDE DISPOSER.
Attach Dishwasher Drain Connector
If your dishwasher drain hose is 7/8 inch (2.2 cm) ID diameter, go to Instruction 9. If
your dishwasher drain hose is not 7/8 inch (2.2 cm ) ID diameter, you must attach a
dishwasher drain connector to the dishwasher drain inlet. Follow the installation instruc-
tions with the connection kit. (You will connect the dishwasher drain hose to the con-
nector in Instruction 12.)
If you are not connecting a dishwasher to disposer, go to Instruction 9.
Disposer Circuit Requirements
Ensure the following electrical requirements are met before connecting disposer to switch (see Figure 9-1 for typical direct wired
electrical circuit diagram):
•Remove fuse (or open the circuit breaker) before connecting disposer to circuit.
•If junction box is used, connect the junction box to the switch on a separate 15 Amp, 120 Volt AC circuit with the appropriate cable.
(Use 14 gauge wire with 15 Amp circuit).
•If you install a double receptacle to handle other small kitchen appliances, include a wall switch in disposer receptacle circuit and wire
other receptacle directly to power source.
•This disposer requires a switch with a marked "Off" position (wired to disconnect all ungrounded supply conductors) installed within
sight of the disposer sink opening (1 HP minimum rating).
WARNING
Electric Shock
•Disconnect electrical power at fuse box or circuit breaker before
installing or servicing disposer. Failure to do so can result in
death or electrical shock.
