exceeds 12 bar then it will
be necessary to adjust the expansion valve
in such a manner that the pressure never
exceed 12 bar.
In normal operating conditions, the coffee
boiler pressure gauge can read anywhere
from 0-12 bar. When brewing,
the pressure should be set to
approximately 9 bar. When the espresso
machine is ready to operate all lights on
the keypads will light up.
NOTE: As the steam boiler reaches operating
temperature you may hear air and steam escaping
from the boiler. This is a normal sound. As the water
boils, air in the boiler is replaced by steam and
exits through the vacuum breaker. As the boiler
get closer to operating temperature the vacuum
breaker closes and the steam is no longer able to
escape. This process allows the air in the steam
boiler to escape and to be replaced by water vapor.
