DECAFF DISPENSING CYCLE
When the machines are supplied (whenever the decaff
funnel is available), the decaff flap is locked
As required by the location, you may decide to unlock
the flap in order to be able to pour decaffeinated coffee
or alike manually
It is necessary to make sure that no other type of prod-
ucts is poured.
A magnet arranged on the flap for pouring decaff coffee
will signal to the machine by means of a sensor on the
door that the flap has been opened.
The following message will flash on and off on the dis-
play:
Decaff
The selections based on decaffeinated coffee are dis-
pensed without acting on the grinder.
The brew cycle is the same as the espresso coffee cycle.
If the decaff dispensing cycle is cancelled before dis-
pensing, the “decaffeinated” pre-selection is cancelled.
The machine will rotate the brew unit to discharge the
decaff power that has been poured.

MILK DISPENSING CYCLE
As soon as the drinks are required to be prepared with
milk, the steam solenoid valve is opened (EVVAP) and
the milk pump activated.
Milk is heated and emulsified with air.
At the end of the selection, a small hot water quantity
(opening of the ELAV solenoid valve) is conveyed to the
milker nozzle for a partial wash cycle.
A partial wash cycle is not intended to replace the
necessity to disassemble the milker nozzle for sani-
tising purposes regularly
