particles from the group. Some also lush
just after brewing coffee for the same
reason. Please experiment to ind the best
possible procedure for you.
7) Controlling the brew process using volumetric
programming (AV model only)
This espresso machine allows the
volumetric programming of each of the
irst two buttons on each group (numbered
left to right). Please consult the
Software Programming Manual for further
instructions.
8) General notes for coffee preparation
The portailters must remain heated since
they are at the lowest position of the
group itself, and they are partially isolated
due to the rubber gasket between them.
This can be accomplished by leaving the
portailters installed in the machine when
not in use. The portailters may also be
actively heated. This procedure may be
carried out by brewing some hot water
through the portailter then turning off the
water low, before making coffee.
It is important to remember that coffee left
over in the ilters must be removed only
when you need to prepare another cup,
and only at that time should you place a
new dose of ground coffee in the ilter.
The size of the coffee granules is extremely
important in preparing a good cup of
coffee, other than the type of coffee mix
used, quite obviously. The ideal grinding
can be determined by making various
coffees using the amount of ground coffee
that you would normally use for each cup
(we recommend at least 6-7g). The best
grinding is that which allows coffee to low
out from the ilter holder spouts neither
too slowly (drop by drop) nor too quickly
(quick light brown low). A general rule
is that a double dose should dispense
approximately 25cc or 2 luid oz. of
espresso in approximately 25 seconds.
IMPORTANT
To improve the lavor of the espresso, the
temperature of the water in the coffee boiler
and therefore of the groups may eventually
be raised or lowered via the digital display
(please consult the Software Programming
Manual for detailed instructions).
WARNING
DO NOT REMOVE THE FILTER HOLDER WHILE RELATIVE
GROUP IS BREWING HOT LIQUIDS. THE COFFEE BOILER
CONTAINS WATER AT ELEVATED TEMPERATURE. WATER
TEMPERATURE OVER 125°F / 52°C CAN CAUSE
SEVERE BURNS INSTANTLY OR DEATH FROM SCALDING.
