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.

DANGER

NOTE: Terminal box and trim band are removed for all repairs except overload and start capacitor.

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.

Removal

1. Remove screw and terminal box (Figure 8).

2. Remove two screws securing trim band (Figure 9).

3. Spread the trim seam. While pivoting trim band upward and forward, slip band over terminal box bracket and remove band from disposer.

Installation

DANGER

1. Insert trim band onto unit. Secure with two screws and tighten.

2. Install terminal box with overload protector positioned through rubber grommet. Take care not to pinch lead wires in terminal box.

3. Secure with screw.

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

Replacing Water Inlet

NOTE: It is not necessary to remove the disposer to repair water inlet.

Water Inlet Kit part number is 13956.

1. Using a wrench, remove water inlet from upper body (Figure

10).

2. Remove any burrs on water inlet hole.

3. Wrap Teon tape around new water inlet tting and insert tting through water inlet hole from inside of upper body.

4. Place O-ring in groove in water inlet nut. A small amount of grease may be used to hold O-ring in place during installation.

5. From outside of body, attach water inlet nut to water inlet tting. Tighten nut with wrench.

NOTE: Water inlet tting and nut are joined with a left-hand thread.

Commercial Disposers

Replacing Shredder Gasket

1. Remove disposer. See “Removing Disposer” on page 7.

2. Remove screws securing tailpipe and gasket from upper end bell assembly (Figure 10).

3. Remove terminal box and trim band (Figure 10).

4. Remove screws securing body and cover assembly to upper end bell assembly (Figure 10).

5. Lift cover and upper body assembly off upper end bell assembly

6. Separate the upper body assembly from the cover.

7. Remove old gasket. Install new gasket to bottom edge of upper body (Figure 11).

8. Place cover over upper body.

9. Place cover and upper body assembly onto upper end bell assembly. There are two tabs on the inside of the cover. These tabs t into the two side grooves on the upper end bell with the waste outlet aligned with the waste outlet cutout.

10. Secure in place with screws.

11. Install trim band and terminal box. See “Terminal Box & Trim Band” on page 9.

12. Re-install tailpipe gasket and tailpipe using screws (Figure

10).

13. Install disposer. See “Installing Disposer” on page 7.

Replacing Stationary Shredder

Removal

1. Remove disposer. See “Removing Disposer” on page 7.

2. Remove cover and upper body assembly. Perform steps 2 – 5 under “Replacing Shredder Gasket” on page 10.

3. Lubricate the full outside diameter of the shredder ring with penetrating oil.

4. Place a 1”D x 1-1/4”L long piece of pipe or similar sized hex socket over rotating shredder nut (Figure 12).

5. Using a 5/16” thick at bar, rest bar on top of pipe or socket with at end under shredder teeth. Strike jam release bar with a soft non-metallic mallet (rawhide, nylon, leather, wood) to break the seal and remove stationary shredder.

Do not strike stationary shredder or shredder could be damaged.

Installation

1. Clean old silicone and dirt from upper end bell.

2. Apply water resistant silicone sealant around bottom of stationary shredder.

3. Place stationary shredder on upper end bell, aligning one stationary shredder groove with upper end bell weep hole (Figure 13). Strike stationary shredder rmly on alternate sides with soft mallet until securely seated.

Do not use metal hammer or die cast stationary shredder will break.

4. Turn rotating shredder by hand and make sure it rotates freely.

5. Install cover and upper body. Perform steps 8–13 under “Replacing Shredder Gasket” on page 10.
