THERMOSTAT CHECK
1. Immerse the thermostat in water, and heat the water while
stirring. Check the thermostat valve opening temperature.
Standard value: Valve opening temperature: 76.5
±
1.5
° C (170 ± 3° F)
2. Check that the amount of valve lift is at the standard value
when the water is at the full-opening temperature.
NOTE: Measure 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:90
° C (194° F)
Amount of valve lift: 8.5 mm (0.33 inch) or more
