7.1 INTRODUCTION
This troubleshooting guide is intended to aid service/maintenance personnel in isolating the
cause of a fault in a RECON Water Heater. The troubleshooting procedures contained herein
are presented in tabular form on the following pages. These tables are comprised of three
columns labeled: Fault Indication, Probable Cause and Corrective Action. The numbered items
in the Probable Cause and Corrective Action columns correspond to each other. For example,
Probable Cause No. 1 corresponds to Corrective Action No. 1, etc.

OnAER communications via a portable computer.
When a fault occurs in the unit, proceed as follows to isolate and correct the fault:
