Next it will be necessary to check the expansion valve. As the coffee boiler heats to operating temperature the pressure
in the coffee boiler will rise. There is an expansion valve behind the drain tray that allows some water to escape during
this process to limit the maximum pressure in the coffee boiler to 13 bar. Please monitor the coffee boiler pressure gauge
during the initial heating process. You should notice the gauge approach 13 bar and stop. If the pressure gauge does not
reach 13 bar or if the pressure gauge rises above 13 bar, then it will be necessary to adjust the expansion valve. Please
follow the next step to properly adjust the expansion valve.
