Installation Steps
Step 1-8: Remove Existing Disposer
- Step 1: If replacing an existing disposer, proceed to Step 2. If no existing disposer, disconnect sink drain and skip to Step 9.
- Step 2: Turn off electrical power at the circuit breaker or fuse box. Disconnect the drain trap from the waste discharge tube. Disconnect the dishwasher if it is connected to the disposer.
- Step 3: While supporting the disposer, insert a 1/4" Allen wrench or screwdriver into the right side of the mounting lug and turn. The disposer will fall free.
- Step 4: Flip the disposer over and remove the electrical cover plate.
- Step 5: Disconnect the disposer wires from the electrical supply.
- Step 6: Determine if the new disposer mounting is the same as the old one. If YES, you may skip to Step 15. If NO, continue to Step 7.
- Step 7: Using a flathead screwdriver, loosen the 3 screws on the mounting assembly.
- Step 8: Using a flathead screwdriver, pry off the snap ring (G).
Step 9-11: Install Flange in Sink Hole
- Step 9: Remove the old flange from the sink. Remove old plumber's putty from the sink with a putty knife.
- Step 10: Evenly apply a 1/2" thick rope of plumber's putty around the sink flange (B).
- Step 11: Press the sink flange (B) firmly into the sink drain. Remove excess putty. NOTICE: Property Damage: Risk of long/short term water leakage if not properly assembled.
Step 12-14: Attach Upper Mounting Assembly
- Step 12: Place a weight, such as the disposer, on the sink flange to hold it in place. Use a towel to avoid scratching the sink.
- Step 13: Insert the fiber gasket (C), backup flange (D), and mounting ring (E). Hold these in place while inserting the snap ring (G). Pull the snap ring (G) open and press firmly until it snaps into place.
- Step 14: Tighten the 3 mounting screws (F) evenly and firmly against the backup flange.
STOP! If connecting a dishwasher, remove the drain plug in Step 15.
If not connecting a dishwasher, continue to Step 16.
Step 15: Dishwasher Connection
IMPORTANT: Dishwasher connection only
NOTICE: If the dishwasher connection is made without removing the plug, the dishwasher may overflow.
Turn the disposer (H) onto its side and knock out the drain plug with a screwdriver. Remove the plug from the inside of the disposer with pliers. NOTICE: The drain plug cannot be replaced once it is knocked out.
Step 16-21: Connect to Electrical Supply
(Proceed to Step 22 for corded units)
- Step 16: Remove the bottom cap from the motor by loosening the top nuts with a 7 mm socket wrench.
- Step 17: Install a 3/8" metal cable connector securely and tighten using a screwdriver.
- Step 18: Feed the power cable through the metal cable connector.
- Step 19: Using wire nuts, connect the white (neutral) wires together. Then connect the black (hot) wires together. WARNING: Improper grounding can result in electric shock hazard.
- Step 20: (1) Loosen the green ground screw from the grounding bracket. (2) Secure the ground wire from the power cable to the grounding bracket using the green ground screw and tighten.
- Step 21: Tuck wires into the lower end frame housing and reinstall the motor cap by securely tightening the nuts. Do not overtighten. Secure the power cord by tightening the metal cable connector with a screwdriver.
Step 22-23: Install Discharge Tube
- Step 22: You may need to trim the discharge tube (I) to ensure proper fit.
- Step 23: Slide the flange (K) over the discharge tube (I). Insert the gasket (J) into the discharge outlet. Secure the flange and discharge tube to the disposer with two bolts (L). Although the supplied discharge tube is preferred, a straight discharge tube may be used.
Step 24-26: Connect Disposer to Mounting Assembly with Lift & Latch® and Complete Installation
NOTE BEFORE INSTALLING THE DISPOSAL: Lift & Latch Technology features a lower mounting ring that is fixed with a tab; the lower mounting ring will not turn freely on the disposal. This is intentional for ease of installation and lifting the disposal with two hands. Review how the lower mounting ring tabs interact with the ramps on the bottom of the flange prior to installation.
- Step 24a & 24b: Lift the disposer to align with the flange. Ensure all three (3) mounting tabs on the lower mounting ring are aligned with the lowest part of the three (3) ramps on the flange. Slightly push/compress the mounting gasket against the flange and turn the disposal to the right to slide up the ramps. Verify all three tabs are engaged on the flange ramps.
- Step 24b (continued): Once the lower mounting ring is secure on the flange ramps, the disposal will rotate freely. Rotate the disposal to the right and align with plumbing. Do not turn the disposal to the left as it could fall off the flange ramps. Lock the flange in place by using a 1/4 inch Allen wrench or screwdriver for leverage. Insert the Allen wrench or screwdriver into one of the hooks on the lower mounting ring and turn right until all three tabs are over the ridges on the high side of the ramps.
Tip: Pliers (not included) can also be used to help secure the disposal on the ramps by clasping one end on a hook and the other end on one of the three lobes of the flange. - CAUTION: To avoid leaks and/or potential falling hazard, make sure all 3 mounting tabs are latched over ridges. WARNING: Do not position your head or body under disposer; unit could fall during removal or installation. NOTICE: Property Damage: Risk of long/short term water leakage if all three mounting tabs are not properly engaged on all slide-up ramps and locked in place past the ridges.
- Step 25: Rotate the disposer to align with plumbing and reconnect plumbing (and dishwasher reconnection if used).
- Step 26: To test for leaks, insert the removable sink baffle (M) into the sink opening (B), press down evenly until it snaps into place. Insert the stopper (A) into the sink opening, fill the sink with water, remove the stopper (A) to drain, then look under the sink for leaking water. NOTICE: Property Damage: Risk of long/short term water leakage if not properly assembled. You may need to trim the tube for proper fit. To reduce the potential of leaking, the drain line must be properly pitched (not less than 1/4" of pitch per foot of run) from the disposer to the drain connection, with the drain connection being lower than the disposer discharge. Failure to do so could lead to premature corrosion or leaking due to standing water left in the disposer.
Operating Instructions
- Remove the stopper from the sink opening and run cold water.
- Turn on the disposer.
- Slowly insert food waste into the disposer. WARNING! Position the stopper to minimize possible ejection of material while grinding.
- After grinding is complete, turn the disposer off and run water for a few seconds to flush the drain line.
DO:
- First turn on cold water and then turn on the disposer. Continue running cold water for several seconds after grinding is completed to flush the drain line.
- Grind hard materials such as small bones, fruit pits, and ice. A scouring action is created by the particles inside the grind chamber.
- Grind peelings from citrus fruits to freshen up drain smells.
- Use a disposer cleaner, degreaser, or deodorizer as necessary to relieve objectionable odors caused by grease build-up.
NOTICE: Failure to flush the disposer properly may result in damage to the disposer and/or property damage.
DON'T:
- DON'T POUR GREASE OR FAT DOWN YOUR DISPOSER OR ANY DRAIN. IT CAN BUILD UP IN PIPES AND CAUSE DRAIN BLOCKAGES. PUT GREASE IN A JAR OR CAN AND DISPOSE IN THE TRASH.
- Don't use hot water when grinding food waste. It is OK to drain hot water into the disposer between grinding periods.
- Don't fill the disposer with a lot of vegetable peels all at once. Instead, turn the water and disposer on first and then feed the peels in gradually.
- Don't grind large amounts of egg shells or fibrous materials like corn husks, artichokes, etc., to avoid possible drain blockage.
- Don't turn off the disposer until grinding is completed and only the sound of the motor and water is heard.
User Maintenance Instructions
Cleaning Disposer
Over time, food particles may accumulate in the grind chamber and baffle. An odor from the disposer is usually a sign of food buildup. To clean disposer:
- Place the stopper in the sink opening and fill the sink halfway with warm water.
- Mix 1/4 cup baking soda with water. Turn the disposer on and remove the stopper from the sink at the same time to wash away loose particles.
Releasing Disposer Jam
If the motor stops while the disposer is operating, the disposer may be jammed. To release the jam:
- Turn off the disposer and water.
- Dislodge any object(s) by rotating the turntable, in either direction, with a wooden spoon.
- Remove the wooden spoon. Reach into the disposer with tongs and remove object(s).
- The disposer is equipped with an automatic overload switch. If the disposer is controlled by a wall switch, turn off the wall switch and allow the disposer to cool for a period of up to 20 minutes before turning it back on. If the disposer is controlled by a push button air switch, turn it off and unplug the disposer for a period of up to 20 minutes before plugging it back in. (If the motor remains inoperative, check the service panel for tripped circuit breakers or blown fuses.)
Important Safety Instructions
WARNING: Personal Injury: Do not position your head or body under the disposer; the unit could fall during removal or installation.
Grounding Instructions: For all grounded, cord-connected disposers: 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. 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 you are using does not fit the outlet, do not modify the plug or attempt to force the plug into the outlet - have a proper outlet installed by a qualified electrician.
- This disposer must be properly grounded.
- Disconnect power before installing or servicing the disposer.
- Plug must be inserted into a three-hole grounded receptacle.
- All wiring must comply with local electrical codes.
NOTICE: Do not use plumber's putty on any other disposer connection other than the sink flange. Do not use thread sealants or pipe dope. These may harm the disposer and cause property damage.
WARNING: When using electric appliances, basic precautions are always to be followed, including:
- Read all instructions before using the appliance.
- To reduce the risk of injury, close supervision is required when an appliance is used near children.
- Do not put fingers or hands into a waste disposer.
- Turn the power switch to the off position before attempting to clear a jam, or removing an object from the disposer.
- When attempting to loosen a jam in a waste disposer, use a wooden spoon to dislodge the jam.
