The machine should now be heating up (Red light to the right should be on). Keep the
portafilter locked into the group. It will take approximately 10 to 15 minutes for the boiler to
pressurize. You may hear some hissing and gurgling noises as the boiler heats up and the
vacuum break seats; this is normal.
Before Each Use
• Verify the steam and hot water valves are both closed. Your brew lever should be pointing
straight down.
• Place whichever portafilter you intend to use into the group. Turn the power switch on.
Normal Operation
• The top gauge is your boiler pressure gauge. Proper pressure ranges are from .9 to 1.4 bar
maximum as a matter of desired steam capacity. Our technicians set the boiler pressure to
shut off at approximately 1.2 bar before shipment. If you wish to adjust the boiler pressure
of your machine, you can go to the bottom of our web site and click on FAQ, which stands
for ‘Frequently Asked Questions’. There you will find not only a link to explain and show you
how to adjust your pressure stat setting, but also how to make other adjustments you might
want to perform in the future. You can also contact our service department at 800-724-3459
between the hours of 8:00 AM to 5:00 PM EST Monday thru Friday for instructions.
• Although your machine may reach its operating boiler pressure in as little as ten minutes, it
is not ready to make espresso. To make great espresso with thick, rich crema, everything
must be hot: the brew group, the portafilter, and the cup you are brewing into. It will take
between 30 and 40 minutes for the group and portafilter to reach proper brewing
temperature.
• The boiler pressure cycles about 0.2 bar between the high and low point. That is called
your dead ban. For example, if your machine is set so the maximum pressure is 1.2 bar
(green light illuminates), the heating element should come on at 1.0 bar (red light
illuminates). This on-off cycle will occur approximately once every minute and the heating
element will only be on for five to ten seconds.
