Opening-temperature of Thermostat Valve
1. Push down the thermostat valve and put the thread between the
valve and the valve seat.
2. Put the thermostat and the thermometer in the container and
increase the temperature of the water gradually.
3. Take the thread, and float the thermostat in the water. As the
water temperature rises, the valve will open, and the thermostat
will separate from the thread. Measure the temperature at this
moment.
4. Continue to increase the temperature and read the temperature
when the valve opens approximately 8 mm (0.3 in.).
5. If the measurement is out of the factory specifications, replace
the thermostat.
