while stirring.
• The valve opening temperature is the temperature at which the
valve opens and falls from the thread.
• Continue heating. Check the full open valve lift amount.
NOTE:
The maximum valve lift amount standard temperature for water
control valve is the reference value.
• After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.
• If out of the specification, replace water control valve.
INSTALLATION
Installation is in the reverse order of removal.
