Warning !!
6.2 Pressure switch adjustment
When the machine is new the filter-holder sump may
not be aligned (perpendicular to the machine itself)
as shown in the figure at the side, however this does
not effect the efficient function of the same.
After a short period of use the sump will gradually
settle into a correct position.
The pressure switch shown in the figure acts to keep the
boiler pressure constant by engaging or de-activating the
electrical heating resistance.
This pressure switch is already calibrated to 1.1-1.3 bar
during the initial machine testing stage, but should a different
working pressure be required, it is possible to vary the
operational field of the pressure switch using the regulation
screw (U); pressure reduction results in a reduction in tempe-
rature, whilst increasing the pressure will also increase the
water temperature. The regulation direction is shown in the
figure and on the pressure switch itself. The pressure varies
by 0.1 atm for every complete screw turn.
A = Position of closed filter-holder with new machine.
B = Position of closed filter holder with machine after a

The measured amounts of coffee may be
modified (by means of volumetric checking) and
memorized as follows:
- press key T5 (of keyboard relative to group
1) and keep pressed for over 5 seconds and
check that all the keyboard leds come on. In
which case, (by operating on the keyboard
relative to group 1) all the units will be
programmed, while by pressing key T5 of
another unit, only the programming of the
unit on which one is operating is possible.
IMPORTANT !! The settings made on unit 1
(operating on the first keyboard) will be
automatically copied on to all the other units.

English
Press the key corresponding to the
measure to be programmed (key T1 for
example) within 30 seconds
(programming time-out).
The led relative to T5 will remain on, on
all keyboards and the led relative to the
measure being programmed will also
come on (on all the keyboards). During
this state and for the entire coffee measure
programming time duration, the solenoid
valve and pump are activated.
Note: If none of the keys are pressed
within 30 seconds, it will automatically
escape from programming mode.
On pressing key T1 coffee delivery begins,
once the required amount of coffee is
obtained press key T1 again or any other
of the keys of the unit keyboard in order to
suspend coffee delivery. The new impulse
value of the measure is thereby memorized
on the EPROM. Both the solenoid valve
and the pump are de-activated thereby
suspending product delivery and all the
keyboard leds go out.
To proceed with a new programming
operation of other coffee measures T2-T3-
T4 (providing that the programming time
out time of 30 sec is not exceeded) simply
repeat the same operations with the same
sequence as undertaken for key T1.
Press key T5 to immediately escape from
the programming stage.
IMPORTANT: Should the “PRE-
INFUSION” function be active (see par.
7.5). Wait until the pre-infusion function is
complete before stopping delivery in
progress.
NOTE: During the programming of a unit
the function of the other units is deactivated
as well as tea dispensing.
To programme the other units, press the
specific programming key of each unit and
carry out the same operations as
undertaken on unit 1. In this case any
variations in the measures are activated
only on the unit on which one is actually
working.

the machine off and then on again.
Lack of volumetric counter impulses
On starting a volumetric control coffee
cycle, the correct function of the volumetric
counter is checked by the reading of the
number of impulses sent by the same to
the micro-controller.
Should no impulses by recorded for a
period exceeding 5 seconds the LED rela-
tive to the selected measure begins flashing
(ie. the led relative to key T4).
After one minute in which no impulses are
recorded (volumetric counter time out), the
measure underway is automatically
stopped.

It is a good idea to rinse the filters (C) and filter holders (D)
every day in hot water, or even better, place them in hot
water and allow to soak for the whole night in order to
dissolve any greasy coffee deposits.
9 - MAINTENANCE AND
USEFUL ADVICE
It is advisable to leave the filter-holder cups inserted with the
coffee dregs for the entire working day to ensure that the
filter-holder is always at optimum temperature.
In order to ensure that the spouts (B) are kept clean and free
of any coffee deposits which may jeopardize yield, we
advise that before starting work in the morning that you put
filter holder (D) in with empty filter (while machine is hot) and
operate the unit several times.
Do not cover the cup-warmer level with any fabrics or cloths
etc.
Do not use any abrasive or corrosive products for cleaning
the bodywork.
In this way any coffee dust which may have been deposited
between the metal filter (B) and the metal filter holder (A) are
removed. This operation must be repeated every day.
The steam nozzles must be cleaned immediately after use in
order to prevent the risk of the formation of any scale which
may block the holes and to ensure that any drinks made
subsequently do not absorb any unpleasant odours.
Frequently check the filter holes (C) and remove any deposits.
Should the water have been left in the ducts for a long time,
it is necessary to allow some water to flow through them in
order to remove any deposits.
Weekly cleaning operations
Cleaning of the unit and spouts: place a teaspoon of specific
coffee machine washing powder into the blind filter supplied
with the machine and apply to the unit to be cleaned using
the filter-holder. Press the unit delivery control button as for a
normal coffee dispensing operation. Suspend delivery after
30 seconds and then repeat the operation 3-4 times. Rinse
out the unit using a normal filter and then undertake a few
dispensing operations using water only. Then prepare a
coffee in order to eliminate any unpleasant odours.

Below-cup seal replacement
Seal (E) needs to be replaced in the event that coffee leakage
is noted between unit (F) and filter-holder (G), or in the event
that on closing filter holder (D) the unit centre is greatly
exceeded.
fig. 10
Remove the spout (B) by loosening the central screw (G).
Remove the spout holder (A) by loosening the two Allen
screws (H).
Then proceed to remove seal (E) using a screw driver.
After removing the seal undertake to clean the slot and then
re-assemble the new seal taking care to insert it with the
chamfered part turned upwards towards the unit itself.

ELECTRICAL CONNECTION
Before connecting the machine to the power point, make sure that
the rating corresponds with the one indicated on the rating-plate of
the power cord.
Normally, the machines are preset for a star connection with ear-
thed centre point.
V415 - 400 3N~
STANDARD Connection
Star connection with earthed centre point.
Delta connection
V240 - 230 3~
V240 - 230 ~
V240 - 230 ~
To change the connection from a star connection to a
delta connection, modify the connections shown in
the diagram (beside) on the power cord, the input
terminal board (A), and the branching terminal bo-
ard (B).
Single-Phase connection
To change the connection from a star connection to a
single-phase connection, modify the connections
shown in the diagram (beside) on the power cord,
the input terminal board (A), and the branching termi-
nal board (B).
Single-Phase Connection with
Three-Core Power Cord
To change the connection from a three-phase con-
nection to a single-phase star connection, change
the power cord and replace it with a three-core power
cord of the HO7RN-F 3x4 mm2 type (SJO 3x10 AWG
for machines used in the USA).
Add the supplied two jumpers (C) to the input termi-
nal board (A) and modify the connections on the input
terminal board (A) and on the branching terminal
board (B) as shown in the diagram (beside).
