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 specications, power supply, and electrical controls.

Specication Decal

The specication 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. Specication 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 specications 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 ttings

are secure and do not leak.

Electrical Requirements

The electrical wiring on disposers shipped from the factory are

not connected for a specic 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.

ELECTRIC SHOCK! The disposer must be

permanently grounded.

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 ange, pull O-ring down disposer leg,

turn each leg clockwise to raise legs and gain oor clearance.

6. Remove disposer from mounting ange by turning disposer

or loosening bolts as necessary (depending on mounting

ange).

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 ange and turning disposer into ange or tightening

bolts (depending on specic mounting).

3. Adjust legs so unit is supported evenly. Push O-ring up ush

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 ows automatically. Make sure the disposer is

securely mounted and does not leak from any of the connec-

tions.
