a
uTomaTic regulaTion lock
You can stop the operation of the automatic regulation,
for whatever reason it might be necessary.
The grinding wheels remain at the distance reached at
the time when you stop the operation of the automatic
regulator.
c
hecking The wear of grinding wheels
The function intended to check the grinding wheels will
display the warning message “Grinding wheels worn out”
as soon as you power on the machine when the grinding
time is increasing too much compared to the grinding
time stored with the new grinding wheels.
When you replace the grinding wheels, please reset the
average grinding time you have stored by means of the
corresponding menu.
s
ofTware regulaTion of The grinding cycle
If you should change the distance to a considerable
extent for any reason whatsoever, e.g. in order to service
the grinding machines, you can act manually by setting
the change you wish via software.
This value is expressed in 1/6 of a turn of the grinding
wheel ring nut.
- to increase granulometry (coarser grinding), the auto -
matic regulation occurs in one single operation;
- to decrease granulometry (finer grinding), the auto -
matic regulation occurs when the coffee grinder motor
is operating.
Attention! In case of a change to a large extent, the
doser chamber is filled, coffee is released and it is
recommended to pick it up to avoid clogging the
brewing unit.
SET UP
s
elecTion of reference
The led of the reference selection will turn on when you
select the grinder-doser on which you wish to act.
The selection is established by default and it can not be
changed .
c
offee dose
The maximum coffee dose the brewing unit can use is 9
grams.
The dose shall be regulated first by manually acting on
the coffee doser lever.
w
aTer dose
The water quantity to be dispensed, expressed in volu-
metric counter pulses (cdv), is established according to
the type of selection. After having set the water value on
the reference selection, the machine will require the user
to enter the brewing time.
B
rewing Time
The coffee dose and water quantity being the same, the
grinding degree will directly affect the brewing time.
If you change this value, the automatic grinding regula-
tion system will act to align the actual time with the one
required.
During the normal operation of the machine, you can
keep the optimal regulation of the grinding degree by
constantly monitoring this time.
o
Ther selecTions
The pre-selected layout will define the dose of a well-
defined selection. For any non-reference selection, the
brewing time is a value that can not be modified and it is
associated with the reference selection.
w
aTer dose
You can define the water quantity (expressed in cdv) to
be dispensed on this selection via software. The coffee
dose and the brewing time will remain those defined for
the reference selection..
INSTANT DISPENSING
Every single instant mixer is supplied by a direct current
pump on the boiler.
The pump rotation speed and flow rate are controlled
electronically to guarantee the best dose constancy and
accuracy.
The water dose for every single selection is established
on a time basis.
Every single mixer can use single or double nozzles, the
cross section of which will vary according to the water
dose required; nozzles are identified by different colours
according to the flow rate you can reach.
The upper nozzle is conceived in such a way that it can
provide for a high flow rate. The lower nozzle can guar -
antee the flow necessary to wash the mixer optimally.
The dose table is intended to specify factory settings
(water and powder doses) and the type of nozzle (colour
/ single or double) used for every single pump.
In case of disassembly of the instant shelf, pay attention
to the position of the nozzles assembled on every single
mixer.
