• The valve opening temperature is the temperature at which the

valve opens and the falls from the thread.

• Continue heating. Check the full-open lift amount.

NOTE:

The full-open lift amount standard temperature for the water con-

trol valve is the reference value.

• After checking the full-open lift amount, lower the water tempera-

ture and check the valve closing temperature.
