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,
