# 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.

NOTE: Special mounting instructions are included in the

#5 Short Mounting Kit.

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.
