# 5 MOUNTING ASSEMBLY
Follow these instructions to install a #5 sink flange to a
standard 3 1/2 - 4 inch sink opening.
1. Unscrew the three backup screws (6) until they are
flush with the upper mounting flange (5) surface. Pry
the retainer ring (7) free from the strainer flange (2)
with a screwdriver and separate all mounting assembly
parts (2 - 7).
2. Form a 3/4" thick ring of top grade oil base putty
around the sink opening (use non-hardening putty).
Insert the strainer flange (2) into the sink opening and
press firmly in place. Clean away any excess putty.
3. From underneath the sink, place the strainer flange
gasket (3), backup flange (4) - flat side up, and upper
mounting flange (5) over the strainer flange and hold
them up to the sink. Snap the retainer ring (7) into the
groove on the strainer flange to hold the mounting
parts in place.
4. Tighten the three backup screws evenly until the backup
flange draws snugly against the underside of the sink
and the strainer flange is held securely in place.
5. Place the body flange (9 - lugs upward) over the lip of
the mounting flange (10) and fit the mounting gasket
(8) onto the lip.
6. Place the mounting gasket (11) on the disposer body
flange. Secure the mounting flange (10) to the disposer
body flange with six screws (12) provided.
7. Raise the disposer to the upper mounting flange (5) so
the body flange (9) is positioned with the lugs to the
right of the screws.
8. While supporting the disposer, turn the body flange (9)
to the right until all three lugs are engaged in the
mounting flange (5). Swivel the disposer to align the
discharge outlet with the drain trap. The disposer can
be turned 360 degrees.
9. Align the disposer to the plumbing connection and
insert the service wrench into the left side of a lug and
continue to turn the body flange to the right (approxi-
mately one quarter turn) until it locks onto the notches
on the upper mounting flange.

Special In-Sink-Erator Mountings
4. From the bottom, insert two screws through opposite
sides of the flat gasket (3) and mounting flange, into the
threaded fasteners in the existing flange. The flat gasket
is used only in the #6 mounting assembly. The screws
should protrude about 1/4 inch below the mounting
gasket.
5. Position the disposer beneath the mounting gasket and
raise it to engage the two protruding screws in the dis-
poser body flange keyhole slots. Secure the remaining
screws and position the disposer correctly for the plumb-
ing connections. For 3-10 H.P. disposers, adjust the legs
to support the disposer.
When installing an In-Sink-Erator commercial disposer to a non-In-Sink-Erator style sink bowl, a special mounting adaptor kit
is required. The special mountings are described in the Mounting Adaptor Selection Guide (for more information, call 1-800
558-5712). Figures 6-8 show examples of non-In-Sink-Erator style sinks. (Mounting instructions are included in each special
mounting adaptor kit.)

Drain Line Connections
To allow easy access to overload reset button, the disposer
plumbing should be connected with the electrical control
box facing the operator.
When connecting the drain line, place the “P-trap” as close
to the disposer outlet flange as possible. Do not connect the
drain line to a grease trap, interceptor, or drum trap.
All horizontal runs should be as short as possible, with a
minimum fall of 1/4-inch per foot.
Water Supply Connections
When connecting the disposer to the incoming water supply,
use as few elbows and tees as possible. Connect to the cold
water line only. All water line fittings are 1/2" NPT except the
sink bowl nozzles (1/2" compression).
Install the flow control valve, water solenoid valve, and the
syphon breaker according to the direction of the flow arrows
marked on each valve body (see Figure 9).
NOTE: A syphon breaker must be installed above the sink
flood plane per local plumbing codes.
