C: INSPECTION
Replace the thermostat if the valve does not close
completely at an ambient temperature or if the fol-
lowing test shows unsatisfactory results.
• Inspection method
Immerse the thermostat and a thermometer in wa-
ter. Raise water temperature gradually, and mea-
sure the temperature and valve lift when the valve
begins to open and when the valve is fully opened.
During the test, agitate the water for even temper-
ature distribution. The measured value should
meet the specification.
NOTE:
• Leave the thermostat in the boiling water for
more than five minutes before measuring valve lift.
• Hold the thermostat with a wire or the like to
avoid contacting with container bottom.
