actively heated. This procedure may be
carried out by brewing some hot water
through the portafilter then turning off the
water flow, before making coffee.
It is important to remember that coffee left
over in the filters 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 filter.
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 flow
out from the filter holder spouts neither
too slowly (drop by drop) nor too quickly
(quick light brown flow). A general rule
is that a double dose should dispense
approximately 25cc or 2 fluid oz. of
espresso in approximately 25 seconds. 8) Dispensing Operations
The Modbar espresso tap is able to
command multiple functions using a
single handle.
We do this by momentarily moving the tap
handle in either the up or down position.
It is possible to set four distinct operations
between seven available operations by the
module keypad.
Short up
The tap handle is raised and immediately
allowed to return to the resting position
Short down
The tap handle is lowered and immediately
allowed to return to the resting position
Long up
The tap handle is raised and held for 2
seconds before being allowed to return to
the resting position
Long down
The tap handle is lowered and held for 2
seconds before being allowed to return to
the resting position
Seven operations available:
- Dose 1;
- Dose 2;
- Dose 3;
- Dose 4;
- Continuous Operations;
- Rinsing;
- Cleaning cycle.
Volumetric Operations (Dose 1, Dose 2, Dose 3,
Dose 4)
Volumetric mode dispenses water until
a preset amount of water is delivered, at
which point the machine automatically
ends the extraction.
The handle back to Position 2 to dispense
at the programmed MEp and/or return the
handle to Position 1 to cease dispensing.
