5 ATTACH UPPER MOUNTING ASSEMBLY TO SINK FLANGE You may wish to place a weighted object in the sink to hold the sink flange in place. (Place a towel under object in sink to prevent scratching.) Reference Figure 5-1 for part identification. 1. Working from under sink, slip rubber gasket and pressure plate over sink flange. 2. Holding rubber gasket and backup ring in place, slip upper mounting ring over sink flange so it seats against pressure plate. 3. With rubber gasket, pressure plate, and upper mounting ring tight to sink bottom, slide snap ring onto sink flange until it pops into groove on flange*. 4. Tighten three mounting screws up to sink until mounting assembly is seated tightly and evenly against sink. Sink Flange Rubber Gaskets (2)** Pressure Plate Upper Mounting Ring *Placing a thick, wide rubber band around the sink flange (above the snap ring groove) may help hold parts in place while installing snap ring. (Remember to remove rubber band after snap ring is installed.) Screws (3) Snap Ring If replacing an existing disposer, go to Instruction 6. If this is a first time installation, skip ahead to Instruction 7. 6 REMOVE EXISTING DISPOSER **NOTE: One rubber gasket is on sink flange above the sink and one is on the sink flange under the sink. WARNING Electric Shock •Turn off electrical power at fuse box or circuit breaker before removing electrical cover plate. •Disposer must be grounded. Improper connection can result in electric shock. CAUTION •Do not position your head or body under disposer; unit could fall during removal or installation. 1. Turn off electrical power at fuse box or circuit breaker. 2. Disconnect drain trap from disposer waste discharge tube with adjustable pliers (see Fig. 6-1). (Disconnect dishwasher drain connection, if required.) 3. Support disposer with one hand and insert end of wrenchette or screwdriver into right side of one mounting lug on lower mounting ring (see Figure 6-2). Lift disposer slightly and loosen lower mounting ring by pushing or pulling wrenchette or screwdriver to left until disposer is free from mounting assembly. (Disposer may be heavy - provide support.) 4. With electrical supply turned off, turn disposer upside down and remove electrical cover plate (see Figure 6-3). Loosen green ground screw and remove wire nuts (see Figure 6-4). Disconnect disposer wires from electrical supply wires. Loosen screw(s) on electrical clamp connector and remove wires from disposer. •If the new disposer mounting is the same as old one, remove mounting assembly from disposer (Instruction 3) and go to Instruction 7. •If the new disposer mounting is different from the old one (or you wish to replace the old sink flange) you must complete Steps 5 - 6 (below), and Instructions 2 - 5, then continue with Instruction 7. 5. Loosen three mounting screws, pry snap ring off with screwdriver, and remove old mounting assembly (see Figure 6-5). (Some mounting assembly removal requires additional tools.) 6. Push old sink flange up through sink hole (see Figure 6-6). Use screwdriver or putty knife to scrape all old compound and other material from edge of sink hole. 4 7 CLEAN SINK DRAIN LINE Failure to clean sink drain line may result in drain line blockage. 1. Remove P-trap. 2. With drain auger, clear all hardened waste material in horizontal drain line. If you are not connecting a dishwasher to disposer, go to Instruction 9. 8 PREPARE DISHWASHER DRAIN CONNECTION (IF APPLICABLE) The knockout drain plug should only be removed if you are connecting a built-in dishwasher to the disposer. NOTE: If the dishwasher connection is made without removing the plug, the dishwasher may overflow. (Connections must comply with local plumbing codes.) Remove Knockout Plug 1. Lay disposer on its side and insert screwdriver into dishwasher inlet so tip rests on outer edge of knockout plug. 2. Tap end of screwdriver handle with hammer until molded plug breaks loose (see Fig- ure 8-1). 3. REMOVE LOOSE KNOCKOUT PLUG FROM INSIDE DISPOSER. Attach Dishwasher Drain Connector If your dishwasher drain hose is 7/8 inch (2.2 cm) ID diameter, go to Instruction 9. If your dishwasher drain hose is not 7/8 inch (2.2 cm ) ID diameter, you must attach a dishwasher drain connector to the dishwasher drain inlet. Follow the installation instructions with the connection kit. (You will connect the dishwasher drain hose to the connector in Instruction 12.) 9 CONNECT DISPOSER TO ELECTRICAL SUPPLY WARNING Electric Shock •Disconnect electrical power at fuse box or circuit breaker before installing or servicing disposer. Failure to do so can result in death or electrical shock. Disposer Circuit Requirements Ensure the following electrical requirements are met before connecting disposer to switch (see Figure 9-1 for typical direct wired electrical circuit diagram): •Remove fuse (or open the circuit breaker) before connecting disposer to circuit. •If junction box is used, connect the junction box to the switch on a separate 15 Amp, 120 Volt AC circuit with the appropriate cable. (Use 14 gauge wire with 15 Amp circuit). •If you install a double receptacle to handle other small kitchen appliances, include a wall switch in disposer receptacle circuit and wire other receptacle directly to power source. •This disposer requires a switch with a marked "Off" position (wired to disconnect all ungrounded supply conductors) installed within sight of the disposer sink opening (1 HP minimum rating). 5
