Warranty
WASTE XPRESS SYSTEM LIMITED WARRANTY
The InSinkErator® Waste Xpress®, disposer and control centers are warranted against defects in material and
workmanship for one year from the date of installation. The warranty includes parts and labor, provided an
InSinkErator Factory Authorized Service Center performs the service. This warranty does not apply if the failure
is due to: faulty or improper electrical installation, faulty or improper plumbing installation, product abuse or
misuse, accidental damage, clogged drain lines, improperly sized unit (as specifi ed by InSinkErator).
Introduction/Typical Installation
INTRODUCTION
The InSinkErator® Waste Xpress® is a Foodservice
kitchen waste reduction system that utilizes a standard
Foodservice disposer in line with the Waste Xpress
dewatering system. The kitchen waste is ground
through the disposer then transferred to the Waste
Xpress where it is compressed. After the waste is
compressed, the liquids are sent down the drain line
and the solid waste exiting the Waste Xpress is 85%
less in volume (see Figure 1 for typical installation).
Important – These installation instructions are for
the benefi t of the installing contractor. InSinkErator
and/or InSinkErator Factory Authorized Service
Centers do not make original installations. For technical
information not covered in these instructions,
contact the supplier, an InSinkErator Field Sales
Representative, or InSinkErator Foodservice Sales
and Service at 1-800-845-8345.

FEATURES
COMPACT SIZE
The Waste Xpress® is designed to fi t under a 34" high
commercial kitchen table.
WASTE REDUCTION
Reduces volume by 85%.
SAFETY INTERLOCK
The Waste Xpress is equipped with safety interlock
on the discharge chute (see Figure 2). This interlock
prevents the system (disposer & Waste Xpress) from
operating unless the discharge chute is properly seated.
DRAIN CONNECTIONS
• Water outlet should be routed directly to a fl oor drain
(and as close to the Waste Xpress as possible).
• The 2" NPT waste inlet connection can be mounted
on either side.
• The 2" NPT water outlet connection can be mounted
on either side.
• For trough or high water fl ow applications, connect
both Water Outlet connections for optimum
cabinet drainage.
• All drain lines must be a minimum 2" NPT in diameter.
CONSTRUCTION
Stainless steel construction (for physical size see
Figure 3).
WASTE MIX
The Waste Xpress can process non-food waste such
as paper, light and rigid plastic or food wrappings when
mixed with a minimum of 50% food waste.
PROPERTY DAMAGE
Plastic wrap, cans, silverware, rubber, glass and
crockery cannot be processed.

WX-101A Control Features/Mounting Control Center
The WX-101A Control Center is UL® approved for use
with InSinkErator Waste Xpress food waste reduction
systems. The control center operates the disposer and
Waste Xpress. Its main functions are:
• To start and stop the disposer/Waste Xpress system.
• To reverse the direction of the disposer motor
automatically upon restart.
• To start the water fl ow to the disposer.
• To allow water fl ow for several minutes to fl ush the
drain line after the disposer is turned off.

FEATURES
SINGLE BUTTON OPERATION
Disposer and Waste Xpress are controlled by simple
ON/OFF button operation.
AUTOMATIC REVERSE
The disposer motor will reverse its direction of
rotation automatically upon restart. To avoid motor
damage, a delay feature prevents reversing until
the post fl ush is complete.
ELECTRICAL SHOCK
• Ensure that Waste Xpress voltage and phase match
that of the electrical supply, control center &
disposer. Check nameplate for specifi cation.
• Electrical connections should be made by a
qualifi ed electrician and should comply with all
local codes.
• Turn off electrical supply to Waste Xpress,
control center & disposer before attempting to
work on it. Test with a volt meter or circuit tester
to ensure that power is off.
• Do not operate unit with panels removed.
• All components (disposer, WX, control center
and solenoids) must be carefully and permanently
grounded.
• A properly fused disconnect must be installed at
Waste Xpress, control center & disposer electrical
supply source.
• Use only NEMA 4 watertight electrical connectors
when connecting to junction box.
MOUNTING THE CONTROL CENTER
Use the fl anges at the back of the control center
enclosure and only mount panel in the upright vertical
position (door hinge is on the left). See Figure 4.
Locate control center within sight of disposer per
local codes.
WATER SHUTOFF DELAY (POST FLUSH)
After the motor is turned off, the water continues to
fl ow for up to 10 minutes. The length of this post fl ush
is controlled by the water shutoff delay timer. The post
fl ush helps ensure that ground food waste is fl ushed
out of the drain line.
AUTOMATIC TIMED DISPOSER SHUTOFF
This water saving feature allows the system to run for
10 minutes before it automatically shuts off and must
be manually restarted.
LINE DISCONNECT SWITCH
The switch on the front panel of the control center
disconnects the line voltage. It interlocks with the front
cover so that the cover cannot be opened unless the
switch is in the off position.
LOW VOLTAGE CONTROL
Control operates on a 24 V solid state control circuit.
ENCLOSURE
Stainless steel NEMA 4 construction.
WX TIMER HOT WATER SPRAY ADJUSTABLE
Factory set for 2 minutes off 10 second on controls hot
water spray for cleaning of screen.
If box is mounted to the sink table, recess the box so
that the buttons do not extend beyond the table’s edge
(see Figure 4).

Installing Disposer
PERSONAL INJURY
• For safe operation, The minimum required distance
from the table top or trough to the mounting fl ange
is 6 inches for standard body disposers
(as specifi ed by UL). See Figure 5.
• Moving shredder parts may cause serious injury if
a hopper or cone is not properly installed.
PROPERTY DAMAGE
To avoid excess vibration, InSinkErator
recommends a minimum countertop thickness
of 16 gage stainless steel.
DISPOSER MOUNTING
The disposer can be mounted to the sink or trough
using a standard InSinkErator mount or an
InSinkErator mounting adaptor.
CLEAN THE DRAIN LINE
With a drain line auger, clear away all hardened waste
material in the horizontal drainpipe running from the
drain trap to the main waste line.

NOTE: The InSinkErator #5 Sink Flange can not be
used with the Waste Xpress system.
NOTE: InSinkErator must approve attachment to a
non-InSinkErator sink.

InSinkErator Mounting Assemblies
STANDARD MOUNTING ASSEMBLY
1. Place mounting fl ange (1) over the existing collar
adaptor connection lip or sink bowl fl ange (this may
require some force).
2. Push the mounting fl ange up out of the way and fi t
the groove in the mounting gasket (2) onto the
connection lip. Make sure the gasket is fully seated
on the fl ange.
3. Push the mounting fl ange down over the mounting
gasket, fi tting the threaded mounting fl ange fasteners
into the recesses in the top of the mounting gasket.

(2) Mounting Gasket
(3) Flat Gasket
4. From the bottom, insert two screws through opposite
sides of the fl at gasket (3) and mounting fl ange, into
the threaded fasteners in the existing fl ange. The
fl at 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 disposer body fl ange keyhole slots. Secure the
remaining screws and position the disposer correctly
for the plumbing connections. If disposer legs are
included, adjust the legs to support the disposer.

SPECIAL INSINKERATOR MOUNTING ASSEMBLIES
When installing an InSinkErator Foodservice disposer to a non-InSinkErator sink bowl, a special mounting adaptor
kit is required. The special mountings are described in the Mounting Adaptor Selection Guide (for more information,
call 1-800-845-8345 or go to www.insinkerator.com). Figures 8-10 show examples of non-InSinkErator style sinks.
(Mounting instructions are included in each special mounting adaptor kit.)
