OPERATIONAL CHECKOUT AND TROUBLESHOOTING PROCEDURES
USE OF TROUBLESHOOTING TABLE
Troubleshooting Procedures (Table 1) contains troubleshooting information useful to operators in diagnosing and correcting
malfunctions or unsatisfactory operation of the air conditioner. The table lists the common malfunctions an operator is most
likely to encounter. Corrective actions indicate what steps the operator should take.
The operator should determine the malfunction symptom that most closely describes the immediate situation and then
perform the corrective action steps in the order listed.
This manual does not list all possible malfunction symptoms that may be encountered, nor can it list all possible corrective
actions.
A malfunction or corrective action beyond the scope of the operator's capabilities must be reported to unit maintenance.
