Start up
We assume the machine has been properly installed.
Open the water tap and switch on the main electrical switch (not included to delivery).
Turn the on/off switch (Fig. 1 –pos. 7) from position 0 to position 1.
Wait until the boiler pressure gauge (fig. 1-pos.8) reads the working pressure (app. 0.9 bar) and group
display (fig. 1 –pos. 3)reads app. 103°C.
Open the steam handle (Fig. 1 - pos. 1) for some seconds and then close it. This operation avoids milk
resuction into the boiler. Wait until the working pressure has been reached again .
Your machine is now ready to work.

preventing breakdowns or, even worse, personal injuries.
After each use:
• Wipe the steam wand (Fig. 1 - 2) immediately after using with a non abrasive clean damp towel without
touching it directly with any part of the body to avoid injury or damage due to the hot surface of steam
wand end nozzle.
• Do not let the milk bake onto the steam wand.
• Clogged wands and steam valves can be expensive to repair or to replace.
• Burp your steam wand (Fig. 1 -2) immediately after using opening and closing immediately after the
steam valve (Fig. 1 -3).
Caution: Hot steam will come out of steam wand (Fig. 1-2).
Burping the wand will remove the milk residue from the inside of the nozzle.
• Knock used coffee grounds from filter holder and rinse. Re-use or store in brewing head (group) to keep
the filter holder warm. (Please remember to take out filter holders when machine is not operating for
some hours (i.e. at night).
