6) Read the thermometer just when opening the
thermostat. If this reading, which is the temperature
level at which the thermostat valve begins to open, is
out of the standard value, replace the thermostat
with a new one.
Thermostat valve opening temperature
Standard: Approx. 82 °C (180 °F)
7) Keep on heating the water to raise its temperature.
8) Just when the water temperature reaches specified
value, the thermostat valve should have lifted by at
least 8 mm (0.31 in). A thermostat failing to satisfy
either of the two requirements (start-to-open
temperature and valve lift) must be replaced.
Thermostat valve lift "a"
Standard: 8 mm and over at 95 °C (0.31 in and
over at 203 °F)
