6.8 TROUBLESHOOTING—
INTRODUCTION
The information contained in the Troubleshooting
Guide has been compiled from field report data and
factory experience. It contains symptoms and usual
causes for the described problems. However, DO
NOT assume that these are the only problems that
may occur. All available data concerning a problem
should be systematically analyzed before
undertaking any repairs or component replacement
procedures.
In addition to the Troubleshooting Guide, consult the
Supervisor Controller manual for additional
troubleshooting guidelines pertaining to the
Supervisor Controller.
A detailed visual inspection is worth performing for
almost all problems and may avoid unnecessary
additional damage to the compressor. Always
remember to:
1. Check for loose wiring.
2. Check for damaged piping.
3. 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
representative.
