Installation, Operation, and Care of

MODEL FD500 FOOD WASTE DISPOSER

SAVE THESE INSTRUCTIONS

GENERAL

The FD500 disposer features removable hardened steel components and reversible rotation with
grinding in both directions. The disposer is self-feeding, making it unnecessary to force the food waste
into the grinding mechanism.

The FD500 food waste disposer utilizes hardened
steel cutter blocks (1, Fig.1) mounted to a rotating
flywheel (4, Fig.1) and a stationary shredder ring
(2, Fig. 1) to grind food waste to a small particle size
for discharge through waste lines. With the motor
running and flushing water turned on, food waste is
reduced to grinding size by the rotating "hi-bulk"
cutter (3, Fig. 1). Grinding occurs as the food waste
is forced against the shredder ring by the cutter
blocks and the centrifugal force due to rotation.
The flushing water aids the grinding action and
discharges ground food waste into the waste line.

Control groups and accessory groups are available to suit each installation.

INSTALLATION

Immediately after unpacking the disposer, check for possible shipping damage. If the disposer is found
to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, test the electrical service to make sure that it agrees with the specifications on the
disposer data plate.

Use legs and temporary blocking to support the disposer during installation to avoid excessive stress
at welded or soldered cone to table connection.

ASSEMBLY

To attach the disposer assembly to the cone, see Figs. 2 and 4. Remove the ten screws holding the
clamp ring halves in place and remove the clamp ring halves. Raise the disposer into position using
the adjustable legs to bring the disposer into firm contact with the cone flange. Do not place the weight
of the disposer on the cone.

Turn each adjustable foot as required to complete height and level adjustments.

– 2 –

Assemble the clamp ring halves using the ten screws and tighten screws finger tight. Rotate disposer
to the desired position. Tighten the ten screws evenly to form a water tight joint.

For an accessory group D installation, use the mounting flange (1, Fig. 3) included with accessory
group D. See Fig. 3 and the accessory group data sheet.

The disposer is furnished with a waste discharge outlet flange (7, Fig. 5) threaded with a standard 3"
IPS tapered thread. Install waste lines with the shortest possible run and best fall. If possible, use a
fall of

1

⁄4" per foot. The waste exit must be lower than the waste outlet (Fig. 2). The waste lines must
be thoroughly cleaned. Ream burrs from cut pipe ends and use fittings which will permit unrestricted
flow. Drum traps and grease traps must NOT be used.
