Operating the GS/3
Installing the Porta
fi
lters.
Install the porta
fi
lter by
inserting it into the group head and rotate the handle
from left to right. Once the porta
fi
lter is inserted
properly, you can press one of the brewing buttons
on the keypad to start the
fl
ow of water through the
porta
fi
lter. Please refer to the Software Programming
Guide for a description of the functions of the keypad
It is important that the porta
fi
lter is at operating
temperature prior to
fi
lling with coffee. Allow hot water
to pass through the empty porta
fi
lter for a few seconds
before the brewing process to pre-heat the porta
fi
lter.
Note:
It is important to leave the porta
fi
lter installed in
the espresso machine when not in use. The porta
fi
lter
must remain heated for the brewing process to function
correctly.
Brewing Coffee.
It is now possible to remove the
porta
fi
lter to make a coffee beverage. Place some ground
coffee in the porta
fi
lter basket using the single or double
porta
fi
lter basket. Press down on the ground coffee
with the supplied tamper and install the porta
fi
lter on the
GS/3. Press a brew button to begin the brewing process.
Note:
Some users believe it is important to allow water
to pass through the the group head prior to installing
the porta
fi
lter to
fl
ush any remaining coffee oils and
particles from the group head. Some also
fl
ush just after
brewing to do the same. Please experiment to make
the best possible procedure for your coffee. There are
many techniques for brewing espresso. You can
fi
nd
instructions for many techniques on websites, blogs
and forums. Some are even monitored by professional
baristas around the world.

The steam will transfer heat to the liquid raising
its temperature. Be careful not to allow liquid
to overflow in order to avoid severe burns.
Steaming milk for cappuccino’s and other beverages
is very easy but making it just right requires some
skill. Please experiment with various techniques to
fi
nd the best method for your milk. You can
fi
nd many
discussion about the steaming of milk on the internet.
NOTE:
It is important to have a suf
fi
cient volume of
liquid in the steaming pitcher. Therefore if you intend
to steam small amounts of milk it is necessary to use a
small pitcher. If you intend to steam larger quantitles of
milk then it is necessary to use a larger steaming pitcher.
Using too little milk in a steaming pitcher can allow the
milk to be “blown out” of the pitcher. A good rule to
follow is to
fi
ll the steaming pitcher only half full of liquid.
Note:
In order to prevent the heated liquid from being
sucked back into the steam boiler it is recommended
that you purge the steam system after heating any liquid.
Purge the system by opening the steam valve for a few
seconds to allow steam to escape to the atmosphere
from the end of the steam wand. Failure to do so can
cause the heated liquid to transfer from the heated liquid
container to the steam boiler (via vacuum created from
cooling parts). This condition is undesireable and can
cause contamination in the steam boiler.
Preparing Tea and Other hot Drinks.
You may
dispense hot water by using the hot water nozzle. To
dispense hot water press the tea water button (#6).
This button commands the hot water delivery. The
volume of water delivered may be adjusted via the display
(see the Software Programming Manual for further
instructions). The temperature of the water dispensed
may be adjusted by adjusting the mixing valve under the
right side cover of the espresso machine (see machine
description diagram).
