IMPORTANT SAFETY INSTRUCTIONS.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
HOW TO CONNECT ELECTRICITY
If you are not familiar with electrical power and procedures, call a qualified electrician.
DANGER: Improper connection of the equipment-
grounding conductor can result in a risk of electric shock. Check
with a qualified electrician or serviceman if you are in doubt as
to whether the appliance is properly grounded. Do not modify
the plug provided with the appliance if it will not fit the outlet;
have a proper outlet installed by a qualified electrician.
For Models Equipped with a Grounded Cord:
GROUNDING INSTRUCTIONS: This appliance must
be grounded. In the event of a malfunction or
breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a
cord having an equipment-grounding conductor
and a grounding plug. The plug must be plugged
into an appropriate outlet that is properly installed
and grounded in accordance with all local codes
and ordinances. Most houses have electrical outlets
under the sink that are half-hot. This means one
outlet is controlled by the wall switch, while the
other is always hot. The batch-feed or “TC” model
connects to the hot side, while the continuous feed
model connects to the switch side.
INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK OR
INJURY TO PERSONS
The power cord and/or connections must comply
with the National Electrical Code, Section 422
and/or local codes and ordinances.
For Models Not Equipped with a Cord:
If your disposer does not come equipped with a cord,
you can connect it in two ways:
1. Attach a power cord, minimum 18″ in length and
not to exceed 36″ in length. GE Kit #PM3X115
provides the parts needed to make this connection.
or
2. Wire the disposer directly into the house current.
GE recommends that a qualified electrician make
this connection.
To Attach a Power Cord:
GROUNDING INSTRUCTIONS: This appliance must be
grounded. In the event of malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
The power cord (to be installed) must have an
equipment-grounding conductor and a grounding
plug. The plug must be plugged into an appropriate
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
In the absence of local codes and/or ordinances,
the outlet must comply with NEC requirements.
DANGER: Improper connection of the equipment-
grounding conductor can result in a risk of electric shock.
Check with a qualified electrician or serviceman if you are
in doubt as to whether the appliance is properly grounded.
NOTE: Disconnect electric power to disposer circuit before
installation. Turn the circuit breaker to the OFF position or
remove the fuse.
A. Connect the disposer to 110–120 Volt, 60 Hz AC
current only.
B. If a plug-in cord is used, use a three-prong
plug. Ground wire should be attached to the
ground screw in the bottom of the disposer
(end bell).
C.
Use a cable clamp strain relief
connector where power cord
enters the disposer.
To Wire Your Disposer Directly into
the House Current:
GE recommends that a qualified
electrician make this connection.
GROUNDING INSTRUCTIONS:
This appliance must be
connected to a grounded, metal, permanent wiring
system; or an equipment-grounding conductor must
be run with the circuit conductors and connected
to the equipment-grounding terminal or lead on
the appliance.
DANGER: Improper connection of the equipment-
grounding conductor can result in a risk of electric shock.
Check with a qualified electrician or serviceman if you are
in doubt as to whether the appliance is properly grounded.
A. If you use BX cable:
1. Install the cable connector in the hole.
2. Connect white wire to white lead of disposer.
3. Connect black wire.
4. Connect bare ground wire.
If BX cable is not used, provide a separate ground
wire to the nearest grounded connection, using the
screw in the end bell for the ground wire.
B. If your power supply does not include a ground wire,
you must provide one unless metal cable is used.
Attach a copper wire securely to disposer ground
screw and attach other end of wire to the nearest
grounded connection. Use only UL approved ground
clamp. If plastic pipe is used in your home, a qualified
electrician should install a proper ground.
Most houses
have electrical outlets under the sink that are halfhot. This means one outlet is controlled by the wall
switch, while the other is always hot. The batch-feed
or “TC” model connects to the hot side, while the
continuous feed model connects to the switch side.
Trace lead connected to this
blade and attach that lead
to white wire on disposer.
Ribbed
Side
NOTE: When viewing face of electrical plug
with grounding pin at top, the larger left blade
is connected to the identified wire.
READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.

• Channel lock pliers, slip joint • Hammer
• Nut driver
PREPARATION
1. Disconnect electrical power supply to disposer.
2. Remove old disposer or sink flange assembly.
3. Inspect drain line. If it is heavily coated with hardened
grease and accumulations, rout out with a plumber’s
snake.
4. Remove old sealing materials and gasketing from sink
opening, both top and bottom.
NOTE: Top and bottom of sink surfaces must be free
of any materials to prevent leaks.
NOTE: Pay close attention to the order of the sink
flange parts, as they have been correctly assembled
by the factory.
A. Disassemble the sink flange assembly from the
disposer by turning the mount ring to the left
(clockwise) and removing it.
B. Raise the mount ring toward the top of the sink
flange. Remove the cushion mount and the mount
ring. You may want to practice installing the
cushion mount at this point before you are under
the sink.
C. Unscrew the support ring from the sink flange and
remove the fiber gasket. You are now left with the
sink flange and the rubber gasket.
D. The rubber gasket is used instead of plumbers
putty with stainless steel sinks.
E. If no putty is used, insert the sink flange through
the rubber gasket into the sink opening. Do not
turn the flange once it is seated.
F. If you use putty instead of the gasket, form a ring
around the underside of the sink flange. Insert the
flange into the sink opening, press down hard to
squeeze out excess putty. From under the sink,
trim off excess putty flush with the bottom edge
of the sink opening. Use putty sparingly on cast
iron sinks.
G.From underneath the sink,
slip the fiber gasket onto the
exposed sink flange. With
arrows pointing up, screw the
support ring onto the sink
flange and hand tighten until
the sink flange will not move. At
this point you may want to insert the stopper
in the sink and fill with water to check the sink
flange seal and insure there are no leaks.
H.Place the mount ring over
the sink flange and hold in
place while installing the
cushion mount (large side
down). Make sure the
groove on the inside of the
cushion mount fits over the
lip on the sink flange,
similar to putting the lid
on a plastic container.
Run your fingers
around the entire
cushion mount with
slight pressure. Do not press too hard. When the
cushion mount is properly seated, the mount ring
can be pulled downward over the cushion mount
and will be free to turn.
