INSTALLATION OF MOUNTING ASSEMBLY READ COMPLETELY BEFORE STARTING.

NOTE: Pay close attention to the order of the mounting assembly parts, as they have been correctly assembled by the factory

1. Disassemble the mounting assembly from the disposal by turning the lower mount ring until it disengages from the ramps on the mounting ring and the sink flange assembly can be removed. Loosen the 3-mount screws until the mounting ring can be moved up to the backup flange
2. Use a flat blade screwdriver under one end of the snap ring to remove it from the sink flange. Remove the mounting ring, backup flange and fiber gasket from the sink flange. Note the sequence of these parts as they are stacked in the correct re-assembly sequence. Keep these parts together and set aside. Note: Mounting assembly can accommodate sink thickness up to 1/2". Extended length sink flange available on MOEN.COM.
3. 
   1. OPTIONAL Flange Alignment: For your convenience, “FRONT” sticker on flange indicates most common logo placement on drain flange above sink. Clean the area around the sink drain where the disposal is to be mounted. Evenly apply ½" thick rope of plumber’s sealant around Sink Flange (B).
   2. Position the Sink Flange (B) in the center of the sink drain opening. Push the sink flange down firmly to make a good seal. Note: Excess sealant will be squeezed out during the installation and should not be cleaned up until installation is complete. DO NOT move or rotate the sink flange once seated or the seal may be broken. Note: Some sink manufacturers may recommend “Non- Staining” plumber’s sealant, check your sink care instructions.
4. Re-assemble the Fiber Gasket (C), Backup Flange (D) and Mounting Ring (F) and Screws (E). From underneath the sink, place the fiber gasket, backup flange and then the mounting ring onto the flange in this order.
5. Using a towel in the sink to prevent scratching, place a weight (or your old garbage disposal) on the sink flange to hold it in place until the sink flange assembly is secured from the underside of the sink. Holding all 3 parts up against the sink, pull the Snap Ring (G) open and press firmly into the groove on the sink flange until it snaps into place. Ensure Snap Ring (G) is locked into place. Failure to properly seat Snap Ring (G) in groove will prevent proper installation.
6. Tighten all three 1½" Screws (E) evenly and firmly against the Backup Flange (D). DO NOT OVERTIGHTEN! Trim off excess sealant in the sink

ATTACHING DISCHARGE ELBOW/ CONNECTING DISPOSAL TO MOUNT ASSEMBLY

7. Install the provided pre-assembled discharge elbow/gasket assembly and flange. Install and tighten two screws evenly with a screw driver. DO NOT RE-USE THE EXISTING DISCHARGE ELBOW AND GASKET AS THE GASKET MAY NOT SEAL PROPERLY. USE ONLY THE NEW ELBOW, GASKET, FLANGE AND SCREWS PROVIDED. DO NOT OVER TIGHTEN!

8. Using a blunt instrument (steel punch or wooden dowel), knock out the entire plug in the dishwasher inlet. Do not use a screwdriver or sharp instrument. IMPORTANT: Do not remove the gasket and place it on the disposal between the elbow and disposal. It must stay on the elbow to make a proper seal. When the plug has been knocked into the disposal, it should be removed using a pair of kitchen tongs and thrown away.

9. If installation requires hardwire electrical connections, proceed to page 11 and complete steps A through G, before proceeding to step 10. If an electrical outlet is available to plug in pre-installed power cord, proceed to step 10.

CONNECTING DISPOSAL TO MOUNT ASSEMBLY

10. Before connecting the disposal to the mounting assembly under the sink, check that the Lower Mounting Ring (I) is in place and the Cushioning Mount (H) is engaged securely around the top lip of the disposal.

11. Align the discharge elbow with the drain connection and hang the disposal by aligning the 3 mounting tabs on the lower mounting ring with the slide-up ramps on the mounting ring

12. Turn the lower mounting ring until all 3 mounting tabs lock over the ribs at the top of the ramps. If you are unable to turn the mount ring by hand, insert a screw driver through one of the tubes on the lower mounting ring to provide extra leverage to turn the mount ring. Use adjustable pliers for final tightening

13. Reconnect the discharge elbow to the drain line. (the reversal of page 3, step A) Use a wrench to secure the drain line where it attaches to disposal discharge tube. DO NOT OVERTIGHTEN. If you are connecting to a dishwasher, go to Step 13. If not, remove any tools, packaging or materials used for installation from the sink. Make sure all plumbing connections are tight and in accordance with all plumbing codes and ordinances (If in doubt, contact a qualified plumber). Run water and check for leaks. Then got to page 11 for the electrical connection.

14. If you are utilizing a dishwasher, complete the following procedure. Connect the dishwasher hose using a hose clamp. A 7/8" inside diameter hose will fit the disposal. If the hose size is different, a Dishwasher Connector Kit should be used.

15.

1. Connect the disposal cord to 110-120 volt, 60 Hz AC current only.
2. This waste disposal is equipped with a factory installed plug-in cord with a three prong grounding plug. If a 110-120 volt, 60 Hz AC grounding outlet is not available, have a proper outlet installed by a qualified electrician, or see section on optional hardwiring in HARDWIRE INSTALLATION section.
3. Outlet must be installed in accordance with local electrical codes. This waste disposal requires that a dedicated switch with a marked “Off“ position. The switch shall be installed within sight of the sink opening or the disposal.
4. If the supply cord is damaged, it must be replaced by a cord assembly available through Customer Service.

OPTIONAL STEPS FOR HARDWIRE INSTALLATION

9. Push wires into the disposal and replace the metal bottom plate (do not displace plastic shield with label).

GROUNDING INSTRUCTIONS

(CORDED INSTALLATION):

• This appliance must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. THIS DISPOSAL 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. For corded installation, do not modify the plug provided with the appliance. If the plug will not fit into the outlet, or if you are in doubt as to whether your outlet is properly grounded, call a qualified electrician. WARNING-Improper connection of the equipment-grounding conductor can result in a risk of electric shock.

(HARDWIRE INSTALLATION):

• This disposer must be connected to a ground, metal, permanent wiring system; or an equipmentgrounding conductor must be run with the circuit conductors and connected to the equipment-grounding terminal or lead on the disposer.

ELECTRICAL CONNECTIONS

NOTE: If you are not familiar with electrical power and procedures, call a qualified electrician.

1. Connect disposal into properly grounded outlet (see Grounding Instructions, above).
2. Outlet must be 110-120 volt, 60Hz AC current only. Outlet must be installed in accordance with local electrical codes.
3. If a properly grounded 110-120 volt, 60Hz AC outlet is not available, have a proper outlet installed by a qualified electrician.
4. Outlet must be controlled by a dedicated wall switch with a marked “off” position, and have a proper switch installed by a qualified electrician.
5. Switch must be mounted within sight of sink opening or disposal.
6. If the supply cord is damaged, it must be replaced by a cord assembly available through Customer Service.

OPERATING INSTRUCTIONS

(NOTE: Reference IMPORTANT SAFETY INSTRUCTIONS during operation of the disposal)

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

1. Remove the sink stopper. Turn on a medium flow of cold water.
2. Turn the switch to the “ON” position; your motor is turning at full speed and ready to use.
3. Scrape garbage into the disposal. Down the drain go table scraps, peelings, rinds, seeds, pits, small bones and coffee grounds. To speed up garbage 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. Important: Do not be alarmed that the disposal slows down while grinding. The disposal is actually increasing torque (grinding power) and is operating under normal conditions.
4. Before turning the disposal off, let the water and the disposal run for approximately 15 seconds after shredding stops. This assures that all waste is thoroughly flushed through the trap and drain.
5. Run cold water during the disposal operation. This will keep waste and fats solid so the disposal can properly flush away the particles. It is not recommended to use hot water while running the disposal.

TIPS FOR SUCCESSFUL OPERATION

• Be sure the disposal is empty before using your dishwasher so it can drain properly.
• You may want to leave the stopper in the drain when not in use to prevent utensils and foreign objects falling into the disposal.
• Your disposal is ruggedly built to give you many years of trouble free service. It will handle all normal garbages, 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. These items may cause damage to the disposal and the plumbing system

BATCH FEED OPERATING INSTRUCTIONS

(Model GXB75c)

1. Remove batch feed stopper and turn on a medium flow of cold water.
2. Scrape in food waste.
3. Insert batch feed stopper to start disposal. Using the arrows on the top of the stopper as a guide, align one of the two small slots on stopper with the activation switch inside the neck of the disposal (see 7A). Push down firmly to turn the disposal on. Lift stopper to shut the disposal off.
4. Run water for 15 seconds after grinding stops. This assures all waste is thoroughly flushed through the drain.
5. To fill sink, insert batch feed stopper and align the largest slot (see 7B) with the activation switch. Push down to seal sink without starting the disposal. When medium sized slot (see 7C) in stopper base is lined up with the activation switch, water can drain but tableware cannot be accidentally dropped into disposal. NOTE: Batch Feed Stopper should be hand washed with mild soap. Do not place in dishwasher.

CLEANING AND MAINTENANCE

• DO NOT ATTEMPT TO LUBRICATE YOUR DISPOSAL!
• The motor is permanently lubricated. The disposal is self-cleaning and scours its internal parts with each use. NEVER put lye or chemical drain cleaners into the disposal, 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 or rust.

TROUBLESHOOTING

Before seeking repair or replacement, we recommend that you review the following:

NOISES:

• (Other than those during grinding of small bones and fruit pits): These are usually caused by accidental entry of a spoon, bottle cap, dishwasher knockout plug (page 8, step 8) or other foreign object.
• To correct this, turn off the electrical switch and the water. After the disposal has stopped running, remove the object from the disposal. WARNING: Never put your hands or fingers inside disposal.
• A humming noise with no grinding could be that the turn table is not rotating (see below).

UNIT DOES NOT START:

• Unplug the power cord or turn either the wall switch or breaker box switch to the “OFF” position, depending on your model and wiring configuration.
• Remove the stopper.
• Check to see if the turntable will rotate freely, in either direction, using a wooden spoon.
• If the turntable rotates freely, check the re-set button to see if it has been tripped.
• The re-set button is red and located opposite the discharge elbow, near the bottom. Push the button in until it clicks and remains depressed.
• If the re-set button has not been tripped, check for shorted or broken wires connecting to the disposal.
• Check the electrical power switch, fuse box or circuit breaker.
• If wiring and electrical components are intact, the unit may have an internal problem that requires service or replacement. NOTE: if you are not familiar with electrical power and procedures, call a qualified electrician.

IF THE TURNTABLE DOES NOT ROTATE FREELY:

• Turn off the disposal and the water, then power off.
• After the disposal has stopped running, check for any foreign object(s) lodged between the turntable and grind ring.
• Dislodge any object(s) by rotating the turntable, in either direction, with a wooden spoon and remove the object(s). Unjamming wrench service kit available for order on moen.com part number 1037.
• If no foreign object is present, there may be an internal problem that requires service or replacement.
• After turning the power back on, press the red reset button before resumming use.

LEAKS:

• If the unit leaks at the top, it may be due to:
  1. Improper seating of the sink flange (gasket centering, sealant or tightening). – Re-check the installation.
