TROUBLESHOOTING
INTRODUCTION
This Troubleshooting section is provided as a guide
to aid in diagnosing and resolving compressor
problems when they occur. The information
contained in Table 5.1, Troubleshooting Guide, has
been compiled from factory experience and contains
symptoms and usual causes for the described
problems. Each Service Reminder, Warning, or
Fault Message is listed with conditions of when the
problem may occur, a probable cause, and a
suggested solution to the problem. DO NOT assume
that these are the only problems that may occur.
This document cannot address every possible
adverse condition that may occur nor does it provide
every solution for the potential troubles listed. All
available data concerning the trouble should be
systematically analyzed before undertaking any
repairs or component replacement procedures.
Always perform a detailed visual inspection when a
machine problem occurs prior to attempting any
repairs. Doing so may avoid unnecessary repair
and/or additional damage to the compressor.
Always remember to:
a.
Check for loose wiring.
b.
Check for damaged piping.
c.
Check for parts damaged by heat or an elec-
trical short circuit, usually apparent by discol-
oration or a burnt odor.
Should your problem persist after making the
recommended check, consult your nearest Sullair
Distributor or the Sullair Corporation factory Service
Department.
