Troubleshooting Guide - Ingersoll Rand PL-MANW Mode D'emploi

The 'Conditions', 'Causes', and 'Suggested Corrections' as indicated below and on the following page(s) are only
a guideline for failures that we have found to be most common.
Though this information is provided in this booklet, it is assumed and expected that any personnel involved in the
servicing of an Air Compressor Unit is knowledgeable with this type of equipment. Do not attempt to service a
Compressor Unit unless you are familiar with it, as there are many issues that may come into play, the most
important being personal safety and the welfare of the Unit.
Should you have any questions, or require servicing to your Unit, please contact your local Ingersoll-Rand
Distributor.
Condition:
A. Unit won't start.
B. No or Insufficient Air
Flow.
