DISASSEMBLE NEW DISPOSER - MOUNTING ASSEMBLY
1. Insert wrenchette (or screwdriver) into one mounting lug and hold lower
mounting ring securely with one hand (see Figure 3-1). With your other
hand, turn mounting assembly counterclockwise to remove mounting
assembly from lower mounting ring.
2. Turn mounting assembly over (see Figure 3-2) and loosen three mounting
screws (A) until you can access snap ring (B).
3. Use screwdriver to pry snap ring off of sink flange. Mounting assembly will
now come apart.

INSTALL FLANGE IN SINK HOLE
Slip one rubber gasket onto sink flange and insert sink flange through sink hole. NOTE: Rubber gasket is preferred sink seal. If sink
opening does not permit use of rubber seal, follow steps below to install flange with plumber's compound.
1. Roll 1/4 pound (4 oz. [113g]) of non-hardening plumber's compound to
make 3/4 inch (1.9 cm) thick rope to seal around sink flange.
2. Apply putty evenly around sink hole (see Figure 4-1).
3. Press sink flange slowly but firmly into sink drain hole to seat evenly on
putty (see Figure 4-2). Use screwdriver or putty knife to scrape all putty
from edge of sink hole.
Do not use plumber's compound on any other disposer connection; it
may harm disposer and cause property damage.

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.
*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.)
If replacing an existing disposer, go to Instruction 6. If this is a first time installation,
skip ahead to Instruction 7.

REMOVE EXISTING DISPOSER
•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.
•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 I I n n s s t t r r u u c c t t i i o o n n 7 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 I I n n s s t t r r u u c c t t i i o o n n 7 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.
