If an error code is displayed, or odd behavior of the unit occurs, the fi rst corrective action should be to “Cycle the
Power”: Unplug the 120Vac power cord and after 5 seconds plug it in again. If this doesn’t clear the fault, proceed with
the “Remedy” in the following table (Table 4). The remedies for each fault code are put in logical order, so proceed one
by one, starting with #1.
If wire harness checking is required, examine the integrity of wires themselves, the connector housings, the integrity of
the terminals as well as condition of the crimps.
