➒ CONNECT DISPOSER TO ELECTRICAL SUPPLY
Electric Shock
• If you are not thoroughly familiar with electric
power, contact a qualified electrician to
connect disposer to electrical circuit.
• Disconnect power before installing or
servicing disposer.
• If three-prong, grounded plug is used, plug
must be inserted into three-hole, grounded
receptacle.
• Do not modify plug provided with unit (if
applicable).
• Improper connection of equipment
grounding conductor can result in 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 or 20 Amp, 115 Volt circuit with the appropriate cable. (Use
14 gauge wire with 15 Amp circuit, and 12 gauge wire with 20 Amp circuit).
• Batch feed disposers do not require a separate wall switch - switch is built into disposer and disposer is wired directly into 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).
Connect Disposer to Electrical Supply/Ground Disposer
Follow these instructions to direct wire the disposer. (If adding a cord
and plug, follow the directions included with the cord and plug).
1. Remove electrical cover plate from bottom of disposer and pull out black and white
wires (see Figure 9-1). DO NOT REMOVE CARDBOARD INSULATION SHIELD.
2. Run electrical cable through access hole (A) on bottom of disposer (with 1/2" conduit or
3/8" flex and secure with clamp connector).
3. Strip wires back approximately 1/2 inch. Connect white (neutral)
electrical wire to white disposer wire, and black (hot) electrical wire to black disposer
wire with wire nuts (see Figure 9-1). Insulate wire connections with electrical tape, and
push connections into
disposer housing without displacing cardboard insulation shield. Do not reinstall
electrical plate until disposer is properly grounded.
• All wiring must comply with local electrical
codes.
• Do not attach ground wire to gas supply pipe.
• Disposer must be connected to grounded,
permanent wiring system, or circuit
conductors must be accompanied by
equipment-grounding conductor and
connected to equipment grounding terminal
or lead on disposer.
• Do not reconnect electrical current at main
service panel until proper grounds are
installed.
If the circuit you are using is grounded at the service panel, attach the
ground wire to the green ground screw (B) in the electrical cover plate
opening and secure the electrical plate (C) (see Figure 9-1).
If the circuit you are using is not grounded at the service panel, complete steps 4 and 5 (below).
4. Attach length of copper wire at least as thick as supply wire to green ground screw (B)
and run wire out through electrical plate opening. Secure electrical cover plate (C).
5. If cold water pipe is continuous metal from sink to ground, attach free end of ground wire
to your cold water pipe (use UL listed ground clamp). (If a nonmetal pipe is used in your
home water connections or water supply pipe, a qualified electrician must install proper
ground.)
Grounding Instructions for Cord Connected Units
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. If this appliance is equipped with a cord having an equipment-grounding
conductor and a grounding plug, the plug must be plugged into
an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
9-1
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 appliance is properly grounded.
If plug is provided with the appliance, do not modify it - if
it will not fit the outlet, a proper outlet must be installed
by a qualified electrician.
CONNECT DISPOSER TO MOUNTING ASSEMBLY
Clear any objects from inside the disposer grind chamber before mounting the disposer to
the sink.
1. P osition disposer with three mounting tabs (A) aligned in position to slide ov er mounting tracks (B) (see Figure 10-1).
2. Lift disposer , insert top end (mounting gasket) into mounting assembly , and turn lower mounting ring to right (with
wrenchette or screwdriver) until mounting tabs lock over ridges (C) on mounting ring tracks (see Figure 10-2).
(MAKE SURE ALL THREE MOUNTING TABS ARE LOCKED OVER RIDGES.)
Disposer will now hang by itself. (NO TE: If a remov able sound baffle is included with disposer , push baffle into sink
opening with “cupped” side upward.)
ATTACH DISCHARGE TUBE TO WASTE DRAIN LINE
Determine the appropriate installation based upon previous installation or plumbing configuration: Threaded Discharge or Bolted Discharge.
Threaded Discharge Tube Installation
If replacing existing disposer, remove and discard existing discharge tube. (Unit will not seal
properly with old discharge tube.)
1. Slide n ut (A) over discharge tube (B), pushing nut o ver elbow into position (see Figure 11-1). The supplied discharge
tube has a beveled end to match the discharge outlet. Do not use supplied washer or gasket for this installation.
2. Screw n ut onto threaded outlet and tighten with adjustable pliers. DO NOT O VERTIGHTEN.
3. Rotate disposer so that discharge tube is aligned with drain trap . (To prevent leaks , do not pull or bend discharge tube
to drain trap.) If discharge tube is too long, cut off as much of tube as necessary with hacksaw (make sure cut is
straight and clean.) If discharge tube is too short, you can purchase an extension from a hardware store. (Disposer
must remain in vertical position to prevent vibration.)
4. Place P-trap nut, then be veled washer (not supplied) on bottom of discharge tube and tighten on drain tr ap. (If y ou
have a double sink, use separate drain tr aps for both sides. )
5. Ensure lower mounting ring is securely lock ed over ridges on mounting flange.
Threaded Straight Discharge Installation
Although the Discharge Tube installation is preferred, if a straight discharge tube is to be
connected to the disposer, follow the steps below. NOTE: If existing straight discharge tube
lines up with discharge outlet, you may use the nut (A) and the flanged gasket (B) to make
the connection, rather than cutting the end of tube as described below (see Figure 11-2).
1. With a hacksaw , cut off flanged end of str aight tube, removing as little as poss.
2. With tapered side of bev eled washer toward disposer , slide nut (A) and be veled washer (C) o ver straight tube (see
Figure 11-3).
3. Rotate disposer , allowing straight tube to slide into discharge outlet a minim um of 1/2” past edge of outlet. (Disposer
must remain in vertical position to prevent vibration.)
4. Tighten nut with adjustab le pliers to secure discharge tube. DO NOT O VER TIGHTEN.
5. Ensure lower mounting ring is still locked on mounting flange .
Bolted Discharge Installation
1. Place metal flange (D) o ver discharge tube (see Figure 11-4).
2. Secure metal flange and discharge tube to disposer with screw .
3. Complete Steps 3 - 5 from Threaded Discharge T ube Installation, above .
CONNECT DISHWASHER DRAIN (IF APPLICABLE)
Connect the dishwasher to the disposer through an air gap (A) (see Figure 12-1). (Most dishwasher
manufacturers recommend that the discharge water runs through an air gap to prevent backflow and/
or dishwasher contamination. Ensure knockout plug is removed (see Instruction 8). Plumbing connections must comply with local codes.
A. If you have a 7/8" diameter dishwasher drain hose, use a hose clamp to attach the drain hose to
the dishwasher inlet. (Verify that hose you are using is rated for dishwasher use.)
B. If you have already attached a dishwasher drain connector to your dishwasher drain hose (for drain
hose other than 7/8" diameter), use a hose clamp to attach the drain hose/connector to the dishwasher inlet on the disposer.
