Resetting the Over-Temperature/Low Liquid Level Safety
Also see Display Messages and Alarms (page 14) and the
Troubleshooting Chart (page 16).
For optimal protection, your Water Bath incorporates redundant over-
temperature safeties. These over-temperature/low liquid level safeties
automatically remove power from the heater in the event that the bath
temperature exceeds their factory set temperature settings.
While these safeties are designed to automatically reset when the
bath returns to a temperature below the factory set safety settings,
we recommend that you take the following actions when the over-
temperature/low liquid level warning is activated.
1. Press to place the Water Bath in the Standby mode.
2. Allow the liquid in the Water Bath to cool to ambient temperature.
3. If the liquid level in the bath is too low, add liquid as required.
4. Press .
