GENERAL INFORMATION

DANGER

CAUTION indicates a potentially hazardous

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.

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 identical. 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.

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 protector 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.

PREPARATION FOR REPAIR

Commercial Disposers

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 disposer 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 support 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.

4. Connect electrical supply wires to the motor leads. Reference 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.

DANGER

6. Connect waste line to disposer.

7. Connect cold water supply to disposer body water inlet (if previously 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 connections.

ELECTRIC SHOCK! Make sure electrical wires are not pinched or damaged when installing terminal box cover.

Installing Disposer

DANGER

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 recommended 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.

1. Remove screw and terminal box (Figure 23).

2. Insert a at blade screwdriver between capacitor clip and capacitor and gently pry capacitor from bracket.

3. Mark and remove lead wires from capacitor terminals. If ag connectors are not present, cut lead wires approximately 1" from terminal on capacitor.

4. Set ohmmeter to highest scale. Connect ohmmeter probes to capacitor terminals (Figure 25).

• If meter does not move, capacitor is open. Replace it.

• If meter needle jumps to zero and stays there, capacitor is shorted. Replace it.

• If meter needle jumps to zero and slowly rises toward innity, capacitor is working.

Installing Capacitor

1. Reconnect wires to capacitor (ag connectors if present - otherwise solder into place).

2. Snap capacitor into place on bracket.

3. Install screw and terminal box (Figure 23).

ELECTRIC SHOCK! A charged capacitor will hold an electric charge until it is discharged or shorted out. DO NOT touch capacitor terminals or electric shock may occur.

TROUBLESHOOTING

DANGER

Commercial Disposers

Disconnect power before troubleshoot-

ing or servicing the disposer.

Troubleshooting problems other than those listed in this section should be performed by qualied service personnel. Any troubleshooting performed by untrained personnel could result in electrical shock or damage to the disposer.

Problem Cause Solution

Disposer will not start but water runs. Overload protector tripped. Allow 5 minute cooling period and reset overload

Overload protector burned out; open circuits.

Stator burned out; open windings

If the problem is electrical:

• To determine if the problem is in the switch or the disposer, 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 corresonding 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.

following steps:

1. Insert the dejamming bar (slot down) through the sink opening. Place the slot over one end of the raised bars found on the top of the rotating shredder.

2. Using an adjustable wrench or a pipe wrench for leverage, twist the dejamming bar back and forth to free the jam. The rotating shredder should move freely when the jam is released.

3. Remove all foreign matter that caused the stoppage.

4. Allow the disposer to cool for 3-5 minutes after it stops running. Press the red reset button to reset the overload protector. Never strike the reset button with and object.

5. If the disposer remains inoperative after following these steps, contact the nearest InSinkErator Factory Authorized Service Center. Call 1-800558-5700 to obtain the telephone number of the nearest center.
