7.5 SPECIAL FUNCTIONS
It is possible to engage or deactivate certain
special functions such as PRE- INFUSION,
MIXED TEA and WASHING ALARM which
we shall describe below:
PRE-INFUSION
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.
MIXED TEA (HOT WATER)
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.
WASHING ALARM
This function acts to indicate, after 10
minutes from the start of the delivery of the
cappuccino or milk, the following signal
“Run Milk Clean” and the alternating
flashing of the LEDs corresponding to keys
T6 and T7 which indicate that a milk or cap-
puccino has been prepared and the milk
section therefore needs to be cleaned.
To temporarily cancel the alarm function
press key T6 or T7.
CAPPUCCINO MACHINE
CLEANING
Cleaning to be undertaken when the “Run
Milk Clean” message appears with the
alternating flashing of the LEDS
corresponding to keys T6 and T7.
Take a 1 litre container full of cold water.
Remove the milk suction pipe from the
container and place inside the container
itself.
Press keys T7 anf T5 at the same time (on
the keyboard activated for the “service”
functions) this engages the milk delivery
function, the water flow will clean the cap-
puccino machine.
Once all the water has been suctioned, stop
delivery by pressing key T7.
