4. Start up
Locate the Portafilter you wish to use. Your machine came with two- a smaller, single portafilter as well
as the larger, double portafilter (left). The single is meant to create about one ounce of espresso at a time,
and the double creates about two ounces- a double. The double portafilter can also be used to make two
singles at one time.
The first time you lock the portafilter in place, you might find that it takes significant force to get it
tight. The proper position should have the portafilter handle pointing roughly straight towards you,
perpendicular to the front of the machine. This properly seats the gasket and shower screen into place.
Leave the portafilter in place while the machine is warming up. This allows the portafilter to warm up the
same as the rest of the machine.
Place a few cups that you will be using on top of the machine. The heat from the machine’s normal
operation will preheat the cups which will in turn keep your beverage warm as you enjoy it.
CAUTION: Do not place items on the top of the machine that are prone to drip or spill or might be
sensitive to heat. Temperatures on top of the machine reach about 63° C ( 145° F).
4.1. Start up: plug the machine
Plug the machine into a surge suppressor capable of handling 10 amper (not included). The outlet must be
properly grounded and should be protected with a GFCI (ground fault circuit interrupter).
Make sure that the Manual Control Lever if in the fully-down position, pushed back nearly against
the front of the machine. Turn the Power switch to position ON. The Power Lamp will illuminate,
indicating that the machine is getting power and the Heating Element Activity Lamp activity indicate
the element is warming up water boiler.
CAUTION: Electrical surges can damage the Vibiemme Domobar electronics. Surges can also damage
the heating element. Damage caused by electrical surges is not covered by the warranty.
4.2. Start Up: boiler warm up
As the machine begins to warm up you may notice a slight hissing sound coming from inside the machine.
This is normal. It is the antivacuum valve. This valve opens as the machine cooled off the last time it was
used to allow air to be drawn into the boiler to prevent a high vacuum being formed which can damage
the machine. When the machine starts up, it takes a little pressure to close this valve, and until it closes
completely it may hiss slightly.
Wait about five minutes for the boiler to gain some heat.
CAUTION: While the boiler is coming up to pressure for the first time you should stay close by to monitor
its progress to be sure that all is as it should be.
WARNING: The Grouphead and other external parts will get hot enough to cause burns.
Use caution when using the machine and if there are any small children in the home (or adults
not accustomed to such appliances) make sure that they are aware of the dangers. Shiny chrome
surfaces invite curious hands!
