2. Support disposer, insert the end of the wrenches into the right side of the mounting lug, and turn. Disposer will fall free.

3. With the electrical supply turned off, flip the disposer over and remove the electrical cover plate. Save cable connector if applicable.

4. With the electrical supply turned off, disconnect the disposer wires from the electrical supply.

5. Loosen the 3 screws on the mounting assembly.

6. Using a screwdriver, remove the snap ring.

7. Remove flange from the sink.

Electrical Connections

WARNING: ELECTRICAL SHOCK

• Disconnect power before installing or servicing the unit. Test the circuit with a voltmeter or circuit tester to ensure the power is off.
• Use only a properly grounded and polarized electric outlet.
• Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
• Installation must conform to all local electrical codes.
• All control centers and disposers must be grounded.

WARNING
PERSONAL INJURY/PROPERTY DAMAGE If the electrical installer is not experienced in electrical installation, we recommend seeking competent professional assistance. Disposer or accessory damage due to improper installation is not covered under warranty. All installations must comply with local electrical codes.

• Turn the disposer over and remove the electrical cover plate. Pull out wires. DO NOT REMOVE CARDBOARD SHIELD.

• With the electrical supply turned off, insert the cable connector (not included) and run the electrical cable through the access hole on the bottom of the disposer. Tighten the cable connector.

• Connect white to white and black to black or red with wire nuts (not included); ground wire to green grounding screw. The unit must be grounded for safe and proper installation.

• Push wires into the disposer (do not displace the cardboard shield) and replace the electrical cover plate.
  Final Installation

• Rotate the disposer around. Place the rubber gasket on the end of the discharge tube and slide on the metal flange from the reverse end. Place assembled discharge tube in the tailpipe mount opening and secure it with the screw provided.

• Hang the disposer by aligning 3 mounting tabs with slide-up ramps on the mounting ring.

• Turn the mounting ring until all 3 mounting tabs lock over the ridges on the slide-up ramps.

• You may need to trim the tube for proper fit. Reconnect plumbing (and dishwasher or direct water connection if used). Make sure the tailpipe mount is straight.

• Insert stopper into sink opening. Fill sink with water, then test for leaks.

Operating Instructions

I mportant – The model LC-50 is designed specifically for light commercial use. Examples of these applications include grocery/convenience store delis, fast food restaurants, office/church kitchens, and bed and breakfast inns. Use of this disposer in applications other than those named above may void your warranty.

OPERATING THE DISPOSER

1. Remove the stopper from the sink opening and run a strong flow of cold water.
2. Turn on the wall switch to start the disposer.
3. Slowly insert food waste into the disposer and 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’S AND DON’TS
DO …

• First, turn on a moderate to strong flow of cold water and then turn on the disposer. Continue running cold water for a few 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.

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 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.

WARNING: PERSONAL INJURY

• 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, remove an object from the disposer, or press the reset button.
• When attempting to loosen a jam in a waste disposer, use the self-service wrenchette.
• When attempting to remove objects from a waste disposer, use long-handled tongs or pliers.
• To reduce the risk of injury by materials that are expellable by a waste disposer, do not operate the disposer without the Quiet Collar Sink Baffle in place.
• Do not put the following into a disposer: clam or oyster shells, caustic drain cleaners or similar products, glass, china, or plastic, large (whole) bones, metal (such as bottle caps, steel shot, tin cans, or utensils), hot grease or other hot liquids.
• Do not dispose of the following in the disposer: paints, solvents, household cleaners and chemicals, automotive fluids, and plastic wrap.

WARNING: ELECTRICAL SHOCK Improper connection of the equipment-grounding conductor can result in a risk of electric shock.

• This disposer must be properly grounded.
• Do not attach the ground wire to the gas supply line.
• Disconnect power before installing or servicing the disposer.
• If the three-prong grounded plug is used, the plug must be inserted into a three-hole ground receptacle.
• All wiring must comply with local electrical codes.
• Do not reconnect the electrical current at the main service panel until the proper grounds are installed.

CAUTION: PROPERTY DAMAGE
Do not use plumber’s putty on any other disposer connection other than sink flange. Do not use thread sealants or pipe dope. These may harm the disposer and cause property damage.
