5.12 TROUBLESHOOTING INTRODUCTION
The information contained in the Troubleshooting
chart has been compiled from 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 the trouble should be
systematically analyzed before undertaking any
repairs or component replacement procedures.
A detailed visual inspection is worth performing for
almost all problems and may avoid unnecessary
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 electrical
short circuit, usually apparent by discoloration or a
burnt odor.
Should your problem persist after making the rec-
ommended check, consult your nearest Sullair
Distributor or the Sullair Corporation factory Service
Department.
