A detailed visual inspection is worth performing for
almost all problems. Doing so may prevent unnec-

Always remember to:
1. Check for loose wiring.
2. Check for damaged piping.
3. Check for parts damaged by heat or an electrical
short circuit, usually apparent by discoloration or
a burnt odor.
Should the problem(s) persist after making the rec-
ommended check, consult your nearest Sullair rep-
resentative or the Sullair Corporation.
