THERMOSTAT CHECK
1. Immerse the thermostat in water, and heat the water while stirring. Check the thermostat valve opening temperature.
  • Standard value: 82 ± 1.5°C (180 ± 34.7 °F)
2. Check that the amount of valve lift is at the standard value when the water is at the full-opening temperature.
noteMeasure the valve height when the thermostat is fully closed, and use this measurement to compare the valve height when the thermostat is fully open.
Standard value:
  • Full-opening temperature: 95°C (203 °F)
  • Amount of valve lift: 8.5 mm (0.335 inch) or more
