Inspection
• Place a thread so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
(The example in the figure shows the thermostat.) • The valve opening temperature is the temperature at which the valve opens and falls from the thread.
• Continue heating. Check the full-open lift amount.
• After checking the full-open lift amount, lower the water temperature and check the valve closing temperature.
• If the measured value is out of the standard value or unusual valve seating condition is found, replace water inlet and thermostat assembly.
