FOODWASTE DISPOSER
REPLACEMENT CONE ADAPTERS
Page 2 of 4 F7543 – Foodwaste Disposer Replacement Cone Adapters
Each year, thousands of commercial
foodwaste disposers reach the age and
condition where it is more practical to
replace than to maintain them.
Adapters are usually required to t
disposers to original cones (including
sink or trough connections). In order to
choose the correct adapter for replace-
ment installation, follow the procedure
below.
PROCEDURE:
STEP 1
Identify Cone type on chart below.
STEP 2
Measure throat opening size of cone
(inside diameter). (Dimension A)
A suggested method is to use two sticks
or pencils. Insert them into the throat of
the cone, sliding them apart until they
touch the sides at the widest part of the
throat. Then remove and measure their
extended length. (Figure 1)
STEP 3
Measure bolt circle diameter (DISTANCE
BETWEEN CENTER OF OPPOSITE
BOLT HOLE). (Dimension B).
If old Disposer is still in place, measure
with calipers or form one from stiff wire.
Bend until ends touch center of oppo-
site bolt heads. Remove and measure
distance between ends. (Figure 2)
STEP 4
When dimensions A & B and Cone Type
have been determined, select proper
adapter from list on facing page.
IMPORTANT: Measure height of old
disposer and check drain size. Compare
to dimensions in specication sheet to
make certain your new disposer will t.
TYPE 1
BOWL TYPE CONE
The Disposer is bolted directly to a
turned-in ange or a loose ring inside
cone.
TYPE 2
CONE W/LARGE FLANGE
The Disposer bolts directly to the ange
on the bottom of this type Cone.
TYPE 3
CONE W/SMALL FLANGE LIP
The Disposer fastens to a small lip on
the bottom of the Cone by one of the
following methods:
1. Two-piece Clamp Rings – spread and
reassemble above cone lip – bolts
fasten to Disposer.
2. Loose Collar Ring slips onto the
Cone before the lip is rolled on the
Cone. The Disposer bolts to the
collar.
3. Molded or hose-type rubber
connector ts over the Cone lip and
is secured by means of hose clamp
type connector.
TYPE 4

Raise Disposer using adjustable support
legs so that the Cone sleeve ts tightly
into a seal in the mouth of the Disposer.

and FD4-150 thru FD4-500. Disposers
with adjustable legs can be used with
this type Cone.
TYPE 5
SLEEVE TYPE CONE
