Introduction

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
servicing the Mini Waste Xpress.
