TROUBLESHOOTING
37
8.1 INTRODUCTION
The following information has been compiled
from operational experience with your package.
It identifies symptoms and describes probable
causes for problems. However
DO NOT
assume
that these are the only problems that may occur.
The collection of operational data concerning
possible trouble should be analyzed to prevent
complete compressor breakdown. An example
of this would be the vibrations signature in-
crease of a damaged bearing or the efficiency
decrease of a dirty heat exchanger.
A detailed visual inspection should be per-
formed for all problems. Always remember to:
1. Check for loose wiring.
2. Check for damaged piping.
3. Check for parts damaged by heat or an electri-
cal short circuit, usually apparent by discolor-
ation or a burnt odor.
Should your problem persist after making the
recommended check, consult your nearest Sull-
air representative or the Sullair Corporation.
