is in the Automatic position.
9. Main Temperature Control - Check that the control’s process temperature matches the Limit
and Pump shutdown controls within 2 o C or 10 o F when the machine is warmed up and no
goods have been fed for several minutes. Make sure the temperature reading is not jumpy
or otherwise unstable.
