Organics Recycling System
Service Manual
Introduction
The InSinkErator®Grind2Energy™Organics
Recycling System is a non-sewer waste handling
system that processes food waste through a
specially designed Grind2Energy grinder.
The food waste is ground, then transferred to
an on-site holding tank where it is stored until
ready for pickup from a liquid waste hauler
for transport to an anaerobic digester where
it is converted into renewable energy such as:
electricity, heat, or Compressed Natural Gas
(CNG).
This Service Manual is intended for Authorized
Serve Agents of Grind2Energy and its
Technicians only. The intention of this manual is
to give the service Tech the ability to diagnose
the Grind2Energy Organics Recycling System
for any problems our customers encounter.
The process G2E will use is to replace larger
components of the system (i.e. Grinder, Pump,
and Controller) as whole components. But in
cases where the small component can be
replaced with less time, then those components
will be provided for those replacements. Our
intent is to recover from a down system, and
back to a fully operational system with one
service call. This philosophy is called One-and-
Done, and provides the customer with peace
of mind that they are supported by the highest
quality service network possible, offering as little
system operational down time as is necessary.

General Information
Prior to Service Call
• Make sure the customer has tried resetting the overload
protector and has checked for foreign objects jammed in the
grind chamber (see
Troubleshooting on page 16).
• Before troubleshooting for mechanical problems, determine
if the problem is electrical:
- To determine if the problem is in the switch or the
grinder, bypass all electrical starting and/or electrical
controls and run the grinder direct.
- Make sure the grinder electrical specifications match the
electric power supply.
- Make sure the motor lead connections are correct for
the corresponding power supply and starting controls.
- Determine if there are electrical problems with other
appliances. This may indicate a problem in the building’s
electrical circuitry.
- Determine that the rotary shredder is rotating in the
direction marked on it by arrows.
After Completing Service
• Test the grinder for proper operation.
• Ensure that the Grind2Energy system is operational per
Manufacturer Specification.
• Ensure that all fittings are secure and do not leak.
