TROUBLE ANALYSIS
If operational difficulties are encountered, be sure to
perform the preliminary checks before referring to the
Troubleshooting Chart.
•
Verify that the unit is receiving electrical supply power.
• Make sure the fuses in the fused disconnect switches
are intact.
After completing the preliminary checks described above,
be sure to inspect for other obvious problems such as
leaking connections, broken or disconnected wires, etc.
If everything appears to be in order, but the unit still fails to
operate properly, refer to the following Troubleshooting Chart.
Troubleshooting Chart
The Troubleshooting Chart that follows is provided to
serve as an aid for identifying malfunctions that may
occur. Within the chart are three columns:
1. The Problem column describes what the unit is doing.
2. The Cause column identifies the most likely sources
of the problem.
3. The Correction column describes what should be
done to correct the problem.
