Part No. 14272 April 2000
MINI WASTE REDUCTION SYSTEM LIMITED WARRANTY
The In-Sink-Erator Mini Waste Xpress, disposer and control centers are warranted against detects in material and workmanship for one year
from the date of installation. The warranty includes parts and labor, provided an In-Sink-Erator 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 specified by In-Sink-Erator).

Introduction
Figure
1-1
The In-Sink-Erator Mini Waste Xpress is a commercial kitchen waste reduction system that utilizes a standard commercial food waste disposer
inline with the Mini Waste Xpress dewatering system. The kitchen waste is ground through the disposer then transferred to the Mini 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 Mini
Waste Xpress is 85% less in volume. (See figure 1 -1 for typical installation.)
PRIOR TO SERVICE CALL
• Obtain the model number, serial number, voltage and phase from the customer to prepare for the service
call.
• Check the service history of the Mini Waste Xpress.
• Make sure the customer has checked for foreign objects jammed in auger area (see troubleshooting).

Defining Problems
DEFINING PROBLEMS
Before troubleshooting for mechanical problems, determine if the problem is electrical.
• Do the Mini Waste Xpress electrical specifications match those of the electrical power supply, control center and
disposer?
• Are the motor lead connections correct for the corresponding power supply?
• If the problem is electrical, determine if there are electrical problems with other kitchen appliances (this may indicate
a problem in the electrical circuitry of the building).
Are the water connections installed correctly?
A hot water supply should be connected to 1/2" copper tube water inlet as specified per local codes.
(In-Sink-Erator recommends installing a shut off valve close to unit).
AFTER COMPLETING SERVICE
Test the Mini Waste Xpress for proper operation and ensure that the fittings are secure and do not leak.
NOTE: Please references the Mini Waste Xpress Parts List (14273) for additional part identification when
Failure to turn off the water and electrical
supply before servicing may result in product
damage or injury.

reliefs.
14. Unscrew two screws securing interlock magnet on
discharge chute and remove interlock magnet (see
figure 1 -4).
15. Install new interlock magnet and secure with two
screws.
16. Install discharge chute.
17. With interlock switch closed, test wires 6 & 7 for
continuity.
• If continuity reads closed, skip to step 18.

DANGER
Electrical Shock
Failure to turn off the water and electrical
supply before servicing may result in
product damage or injury.
1. Turn off power to Mini Waste Xpress at fuse box or
circuit breaker. Turn off water supply to Mini Waste
Xpress.
2. Holding both handles, remove discharge chute by
tilting it upward (see figure 20-1).
3. Remove rear panel by removing the screws securing it
in place (see figure 20-2).
4. Remove cover to control box by loosening the screws
securing it in place (see figure 20-3).
5. Remove the wires to the failed component (timer,
overload or contactor) then remove the component
from the din rail (see figure 20-4).
6. Install new component (timer or contactor) by
snapping it onto the din rail.
7. Wire component as for the specific voltage and phase
as shown on pages 26 through 33.
8. Replace rear panel, control box cover and secure with
screws.
9. Install discharge chute by placing bottom front portion
in first and then tilting back and downward.
10. Turn on power to Mini Waste Xpress at
fuse box or circuit breaker. Turn on water supply to
