It is possible to engage or deactivate certain
special functions such as PRE- INFUSION,
MIXED TEA and WASHING ALARM which
we shall describe below:

Our software permits measure configuration
so that the relative delivery of the COFFEE
measures through volumetric control is
preceded by pre-infusion. Delivery of the
coffee measure after time 1 (ON) is
suspended for a time 2 (OFF) and is then
resumed for the completion of selection.
On pressing one of the volumetric control
measure keys, the normal delivery cycle is
preceded by a short timed water jet in order
to dampen the coffee pellets before actual
delivery stage.
This function ensures the optimum use of
the coffee pellets.

On the engagement of this function the
water delivered is mixed with cold water on
entry in the boiler thereby ensuring constant
delivery at a temperature of about 96°C.
If this function is not engaged water is
delivered at a temperature of about 100°C
and is highly vaporized.

Start the machine by pressing the main
switch keeping key T5 of unit 1 pressed and
wait for the led relative to key T5 to begin
flashing.
Press keys T1-T2 in order to engage or
deactivate the PRE-INFUSION, MIXED TEA
functions.

To escape from this condition and return to
normal functions press key T5 again.

T1 KEY LED ON : PRE INFUSION : ON
T2 KEY LED ON :  MIXED TEA:

ON

On pressing key T6 the corresponding
solenoid valve is engaged thereby beginning
hot water delivery.

On START a timer is activated which
interrupts the water delivery on reaching the
time set during the programming stage.
The simultaneous delivery of tea or coffee
is possible.

It is possible to interrupt delivery function in
progress before the programmed time is
reached by pressing key T6 again used for
product  delivery.
