WARNING – When using electric disposers, basic precautions are always to be followed, including the following:

1. Read all the instructions before using the disposer.
2. To reduce the risk of injury, close supervision is required when a disposer is used near children.
3. Do not put fingers or hands into a disposer.
4. Turn the power switch to the off position before attempting to clear a jam or remove an object from the disposer.
5. When attempting to loosen a jam in a disposer, use a long wooden object such as a wooden spoon or the wooden handle of a broom or mop.

8. When not operating a disposer, leave the drain cover in place to reduce the risk of objects falling into the disposer.

Grounding Instructions
This disposer must be grounded to reduce the risk of electric shock in the event of a malfunction or breakdown. Grounding provides a path of least resistance for electric current. This disposer is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. WARNING – 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 disposer is properly grounded. If the plug provided with the disposer does not fit the outlet, do not modify it. See insert for specific information about your new disposer

NOTE: This Food Waste Disposer has been designed to operate on 110 Volt, 60 Hz exclusively. Using any other voltage or Hz adversely affects performance.
IMPORTANT: Read all instructions thoroughly. Keep this guide for future reference.
CAUTION: Be sure to review SAFETY INSTRUCTIONS FIRST PERTAINING TO A RISK OF FIRE, ELECTRICAL SHOCK OR INJURY TO PERSONS before using disposer.

Important Safety Instructions

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS. SAVE THESE INSTRUCTIONS.
WARNING – When using electrical appliances, basic precautions should always be followed, including the following:

1. Read all instructions before using the appliance.

2. To reduce the risk of injury, close supervision is necessary when an appliance is used near children.

3. Do not put fingers or hands into a waste disposer.

4. Turn the power switch to the off position before attempting to clear a jam or remove an object from the disposer.

5. When attempting to loosen a jam in a waste disposer, use a long wooden object such as a wooden spoon or the wooden handle of a broom or mop.

6. When attempting to remove objects from a waste disposer use long-handled tongs or pliers. If the disposer is magnetically actuated, non-magnetic tools should be used.

7. To reduce the risk of injury by materials that may be expelled by a waste disposer, do not put the following into a disposer: clam or oyster shells; caustic drain cleaners or similar products; glass, porcelain or plastic; large whole bones; metal, such as bottle caps, tin cans, aluminum foil or utensils; hot grease or other hot liquids; whole cornhusks.

8. When not operating a disposer, leave the stopper in place to reduce the risk of objects falling into the disposer.

9. DO NOT operate disposer unless splash guard is in place. (Does not apply to the Top Control/Batch Feed units.)

10. For proper grounding instructions see the ELECTRICAL CONNECTION portion of this manual.

11. Step 1. Removal of Old Unit
    Before starting this step, turn off electrical power at the circuit breaker or fuse box. If your old mount is the same as the mount on your new disposer, just reverse the assembly instructions found in section 3. If your new mount system is different, follow these instructions:

12. Use a pipe wrench to disconnect drain line where it attaches to disposer discharge tube (see 1A).

13. Remove disposer from sink flange by turning mount ring to the left clockwise (see 1B). If you are unable to turn the mount ring, tap on one of the extensions from the ring with a hammer. Some mounting systems have tubular extensions. Inserting a screwdriver into one tube will provide additional leverage for turning the mount ring (see 1B). Some disposers may require the removal or loosening of nuts from the mount screws (see 1C). Some disposers may require the removal of a clamp.
    CAUTION: Be sure to support the disposer while performing this step or it may fall when the mounting ring is disconnected from the mounting assembly. If your disposer is hard wired (metal shielded cable not utilizing a wall plug), complete steps C and D. If you utilize a plug-in cord, go on to step E.

14. When disposer is removed, turn up side down and remove electrical cover plate (see 1D).

15. Use screwdriver to remove green ground wire. Remove wire nuts from black and white power wires and separate disposer wires from power cable wires. Loosen screws on cable clamp and separate cable from disposer.

16. To remove remaining mount system from the sink, loosen mount screws, push mount ring up. Under it is the snap ring. Use screwdriver to pop off ring (see 1E). Remove mount ring, protector ring and gasket from sink flange. Some mounts will require the unscrewing of a large ring holding the sink flange in place. Pull sink flange up through sink and clean off old putty from sink.

IMPORTANT: Unless you have a new home, this is a good time to clean out the trap and drain lines by running a drain auger or plumber’s snake before installing your new disposer. 

Step 2. Dishwasher Connection

If you are utilizing a dishwasher, complete the following procedure. If dishwasher is not to be connected go on to section 3.

1. Make use of a blunt instrument to knock out the plug on the inner body (see 2A). Please take out or grind the knockout plug if it falls into the chamber.
2. Connect dishwasher hose using hose clamp. If hose size is different, you will need a Dishwasher Connector Kit (see 2B). Make sure all plumbing connections are tight and in accordance with all plumbing codes and ordinances. Run water and check for leaks. 

Step 3. Installation of Mounting Assembly

1. Install the sink flange and rubber washer (see 3A).
2. Install the fiber washer, backup flange and mounting ring (see 3B).
3. Install the snap ring (see 3C).
4. Screw in the 3 mounting screws from the bottom (see 3D).

READ COMPLETELY BEFORE STARTING
NOTE: Pay close attention to the order of mount assembly parts, as they have been correctly assembled by the factory. Also, reference the cushion mount detail in illustration 3D below for the proper orientation of the cushion mount.
NOTE: Try practicing this assembly before you get under the sink to get the “feel” of how the parts fit together.

1. Disassemble mount assembly from disposer by turning mounting ring to the left (counterclockwise) and remove.
2. Raise mounting ring toward top of sink flange. Remove mounting seal ring. Remove mounting ring. You may want to practice installing the mounting seal ring at this point before you are under the sink. See paragraph H. Also see the “Important Notice: Mounting Seal Ring Detail.”
3. Unscrew mounting nut from sink flange and remove fiber washer. You are now left with sink flange and rubber washer.
4. The rubber washer is used instead of plumbers putty with stainless steel sinks. Other sinks will require putty.
5. If no putty is used, insert sink flange through rubber washer into sink opening. Do not rotate sink flange once it is seated.
6. If you use putty instead of the washer, form a ring around underside of sink flange. Insert flange into sink opening, press down hard to squeeze out excess putty. From under sink, trim off excess putty flush with bottom edge of sink opening.
7. From underneath sink, slip fiber washer onto exposed sink flange (see 3A). With arrows pointing up, insert backup flange and mounting ring onto the sink flange (see 3B). Install the snap ring onto the sink flange (see 3C). Hand tighten the screws until the sink flange will not move. Tighten mounting screws with the included hex wrench (see 3D). At this point you may want to insert stopper in sink and fill with water to check sink flange seal and insure there are no leaks.
8. Place mounting ring over sink flange and hold in place while installing mounting seal ring (large side down) so the groove on the inside of mounting seal ring fits over lip on sink flange, similar to putting the lid on a plastic container (see 3B, 3C & 3D). Please read important notice below.

Important Notice: Mounting Seal Ring Detail
When the mounting seal ring is installed correctly, the lip of the sink flange fits into the groove on the inside of the mounting seal ring and mounting ring can be pulled downward over mounting seal ring and will be free to rotate. The bottom bead of the mounting seal ring acts as a gasket between the bottom of the sink flange and the top of the disposer. See illustration 3D. 

Step 4. Electrical Connections
Now is the time to record the BATCH NUMBER (located on the bottom of the disposer) onto the warranty card.
IF YOU ARE NOT FAMILIAR WITH ELECTRICAL POWER AND PROCEDURES, CALL A QUALIFIED ELECTRICIAN.
WARNING: Improper connection of the equipment grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service man 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.

Step 5. Attaching Drain Elbow

1. Connect drain elbow to the disposer (see 5A), proceed to step 6 and then connect bottom of the elbow by tightening the slip nut (see 5B).
2. If you are connecting to a dishwasher, return to section 2B. If not, make sure all plumbing connections are tight and in accordance with all plumbing codes and ordinances. Run water and check for leaks. 

Step 6. Connecting Disposer to Mount Assembly

1. Line up disposer under mounting assembly (see 6A).
2. Turn mounting ring and disposer until drain elbow lines up with trap (see 6B).
3. Turn mounting ring to the right (clockwise) until it locks up tight (see 6C).

Step 7. Operating Instructions
The Anti-Jam Swivel Impellers make a clicking sound as they swing into place. This indicates normal operation.

1. Remove sink stopper. Turn on a medium flow of cold water.
2. Turn switch to ON position; your motor is turning at full speed and ready to use.
3. Scrape in food waste. Down the drain go table scraps, peelings, rinds, seeds, pits, small bones and coffee grounds. To speed up food waste disposal, cut or break up large bones, rinds and cobs. Large bones and fibrous husks require considerable grinding time and are more easily thrown away with other trash. Do not be alarmed that the disposer slows down while grinding. The disposer is actually increasing torque (grinding power) and is operating under normal conditions.
4. Before turning disposer off, let water and disposer run for approximately 15 seconds after shredding stops. This assures that all waste is thoroughly flushed through trap and drain.
5. It is not recommended to use hot water while 7A running disposer. Cold water will keep waste and fats solid so disposer can flush away particles. 

TIPS FOR SUCCESSFUL OPERATION

1. Be sure disposer is empty before using your dishwasher so it may drain properly.
2. You may want to leave the stopper in the drain when not in use to prevent utensils and foreign objects from falling into the disposer.
3. Your disposer is ruggedly built to give you many years of trouble free service. It will handle all normal food wastes, but it will NOT grind or dispose of such items as plastic, tin cans, bottle caps, glass, china, leather, cloth, rubber, string, clam and oyster shells, aluminum foil or feathers.

Replacement Parts

Troubleshooting

Before seeking repair or replacement, we recommend that you review the following:
LOUD NOISES: (Other than those during grinding of small bones and fruit pits): These are usually caused by accidental entry of a spoon, bottle cap or other foreign objects. To correct this, turn off electrical switch and water. After disposer has stopped, remove splash guard, remove object with long handled tongs, and replace splash guard.
UNIT DOES NOT START: Unplug power cord or turn either the wall switch or breaker box switch to “°OFF”± position, depending on your model and wiring configuration. Remove stopper and/or splash guard. Check to see if turntable will rotate freely using a wooden broom handle. If turntable rotates freely, replace splash guard and check re-set button to see if it has been tripped. Re-set button is red and located opposite discharge elbow, near the bottom (see 8A). Push button in until it clicks and remains depressed. If re-set button has not been tripped, check for shorted or broken wire connecting to disposer. Check electrical power switch, fuse box or circuit breaker. If wiring and electrical components are intact, the unit may have internal problems that require service or replacement.

Splash guard not used on Top Control/Batch Feed unit.
IF TURNTABLE DOES NOT ROTATE FREELY: Turn off disposer, then check for any foreign objects lodged between the turntable and grind ring. Dislodge object by rotating table with a wooden broom handle and remove object (see 8B). If no foreign object is present, there may be internal problems.
LEAKS: If the unit leaks at the top, it may be due to:

1. Improper seating of sink flange (gasket centering, putty or tightening).
2. Support ring not tightened properly.
3. Defective or improperly installed cushion mount. If unit leaks at the waste elbow, leak may be due to improper tightening of elbow flange screws.

Cleaning and Maintenance

DO NOT ATTEMPT TO LUBRICATE YOUR DISPOSER!
The motor is permanently lubricated. The disposer is self cleaning and scours its internal parts with each use. NEVER put lye or chemical drain cleaners into the disposer, as they cause serious corrosion of metal parts. If used, resulting damage can be easily detected and all warranties are void. Mineral deposits from your water can form on the stainless steel turntable, giving the appearance of rust. DO NOT BE ALARMED, the stainless steel turntables used will not corrode.
