Digital Water Bath:
water bath temperature has reached 100ºC.
Over Temperature Protection
In the unlikely event that the programmed hi-limit and the user adjustable hi-limit thermostats fail, there is a
third over temperature thermostat. The thermostat is located underneath the water bath's bottom panel
attached to the pan. If the water bath fails to heat with the "HEAT ON" lamp lit and the user settable hi-limit
thermostat set to the fully clockwise position, it will be necessary to reset the secondary over temperature
thermostat. To do so, proceed as follows:
1.
Disconnect power cord from outlet.
2.
Drain bath
3.
Remove bottom panel.
4.
Locate the thermostat underneath insulation. The thermostat has a small button that needs to be pressed
in to reset the thermostat.
5.
Once the thermostat is reset, reposition insulation, reinstall the bottom panel, plug the power cord back
into the outlet and verify the unit is heating again.
6.
If the water bath still fails to heat, contact Barnstead International customer service for further assistance.
