Safety Signals
This symbol indicates potential personal injury hazards.
Obey all safety messages accompanying this symbol to
avoid possible injury or death.
DANGER indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.
WARNING indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
CAUTION indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury.
Commercial Disposers
InSinkErator
®
manufactures commercial food waste disposers
with motors ranging from 1/2 horsepower through 10 horsepower.
The basic assembly of all SS Series commercial disposers is iden-
tical. However, electrical connections vary depending upon the
disposer specifications, power supply, and electrical controls.
Specification Decal
The specification decal (Figure 1) located on the motor trim cover
indicates
• complete model number (example - SS150-24)
• serial number (includes manufactured date)
• amperage
• voltage
• phase
• horsepower.
NOTE: The correct part sheet (as designated by the complete
model number) must be referenced to order replacement parts.
DANGER
Figure 1. Specification Decal
Prior to Service Call
• Obtain the model number, serial number, voltage and phase
from the customer to prepare for the service call.
• Date of installation.
• Obtain the service history of the disposer.
• Make sure the customer has tried resetting the overload pro-
tector and has checked for foreign objects jammed in the
grind chamber (see “Troubleshooting” on page 25).
• Before troubleshooting for mechanical problems, determine if
the problem is electrical:
• To determine if the problem is in the switch or the dispos-
er, bypass all electrical starting and/or electrical controls
and run the disposer direct.
• Make sure the disposer electrical specifications match
the electric power supply.
• Make sure the motor lead connections are correct for the
corresponding power supply and starting controls.
• Determine if there are electrical problems with other
kitchen appliances. This may indicate a problem in the
building’s electrical circuitry.
After Completing Service
Test the disposer for proper operation and ensure that the fittings
are secure and do not leak.

Electrical Requirements
The electrical wiring on disposers shipped from the factory are
not connected for a specific voltage. Refer to the Standard Motor
Connection Wiring Diagram attached to the inside of the disposer
terminal box cover for the correct voltage connections.
Standard disposer voltages are:
• 115/208/230 volts for single phase electrical power
• 208/230/460 volts for three phase electrical power
NOTE: All amp ratings denote amp draw during a grind load.
NOTE: The disposer motor phase and voltage must be the same
as the line or power supply.

PREPARATION FOR REPAIR
DANGER
ELECTRIC SHOCK! Turn off water and
electrical supply. Discharge capacitor with
1000 ohm jumper wire (1 Phase only). Do
not use a screwdriver to discharge or
capacitor may be damaged.
Removing Disposer
1. Turn off electrical supply and water supply to disposer.
2. Disconnect cold water connection from disposer body water
inlet (if connected).
3. Disconnect waste line from disposer.
4. Remove terminal box retaining screw and terminal box cover.
See “Terminal Box & Trim Band” on page 9. Mark motor lead
wires and electrical supply wires, then disconnect wires and
grounding wire from disposer.
NOTE: Make sure sink can bear weight of disposer before legs
are loosened. In some cases, support disposer before loosening
or removing legs.
5. If equipped with legs and legs interfere with removing dis-
poser from mounting flange, pull O-ring down disposer leg,
turn each leg clockwise to raise legs and gain floor clearance.
6. Remove disposer from mounting flange by turning disposer
or loosening bolts as necessary (depending on mounting
flange).
7. To remove legs, remove black cap plug from bottom of sup-
port leg (Figure 6). Insert slotted screwdriver into open end of
leg support tube and turn stud counterclockwise until free of
upper end bell. Pull leg from disposer.
Installing Disposer
ELECTRIC SHOCK! Turn off water and
electrical supply. Discharge capacitor
with jumper wire (1 Phase only).
1. If unit was equipped with legs, insert leg assemblies through
end cover guide holes. Insert screwdriver into open end of leg
support tube and turn stud clockwise to install. Install O-ring,
washer and cap to each leg (Figure 6).
NOTE: On models SS-150 thru SS-200, legs are optional and rec-
ommended where the disposer is mounted to a thin gauge sink
(16 gauge minimum), dish table, using a #5 mounting assembly
or non-InSinkErator mounting adaptors. On models SS-300 and
above, legs are factory installed and recessed on the unit.
2. Attach disposer to the mounting assembly by positioning in
mounting flange and turning disposer into flange or tightening
bolts (depending on specific mounting).
3. Adjust legs so unit is supported evenly. Push O-ring up flush
with bottom of unit.
DANGER
4. Connect electrical supply wires to the motor leads. Refer-
ence the wiring diagram attached to the inside of the terminal
box or the Wiring Diagrams section of the Disposer Control
Center Installation manual.
5. Reinstall terminal box.
ELECTRIC SHOCK! Make sure electrical
wires are not pinched or damaged when
installing terminal box cover.
6. Connect waste line to disposer.
7. Connect cold water supply to disposer body water inlet (if pre-
viously installed).
8. Turn on electrical and water supply.
9. Test the disposer to ensure the cutting elements revolve
and the water flows automatically. Make sure the disposer is
securely mounted and does not leak from any of the connec-
tions.
