Procedure to follow at the end of the working day on all groups or when signalled by the machine.
COFFEE CIRCUIT CLEANING CYCLES
The purpose of the ushing cycle is to remove all traces of grease and scaling deposited when the coffee is dispensed
ailure to ush out the circuit will allow these deposits to solidify This will impair the qualitative performance of the coffee
circuit.
NOTE: the following operations must be carried out when the machine is on and pressurized.
ATTENTION, RISK OF SCALDING: During the wash
cycles, hot water and steam will exit from the groups.
Keep the hands and all other parts of the body well
away until the cleaning cycle has terminated.
If the machine sends the warning message (washes are
requested daily at the programmed hour), "EXECUTE
COFFEE WASHING" will appear on the display.
This request will continue to appear for one hour or until
the wash cycle is performed.
The coffee circuit can be washed in different ways:
• sequential: each group is washed separately and in
sequence. It is therefore possible to continue using the
groups not involved in the washing process
• simultaneous: all groups are washed at the same time.
Note: The simultaneous washing mode lasts 7 minutes.
The single washing mode lasts 7 minutes for each coffee
dispenser group.
A third type of washing cycle can also be effected:
• single The washing cycle can be made on a specific
group without having to wash the remaining ones.
Groups not involved in the washing cycle can still be
used during that time.
Note: The single washing cycle cannot be carried out if the
machine launches a warning message.
Note: If no wash-cycle messages appear and the
machine is used frequently, a wash cycle can be
performed at any time:
Note. Once the wash cycle is underway, it CANNOT be
stopped, even if the machine is switched off.
If there is a power failure, when power is returned the
message "EXECUTE WASHING" will be displayed.
Complete the cleaning operations as described pre-
viously.
The wash cycles performed without request by the
machine can be interrupted by switching off and
switching back on the machine.
Programmed wash cycles that are not carried out will be
memorized by the machine.
NOTES. The technical personnel has the ability to enable
or disable the "block" function.
With "block" enabled, if the washing cycle is not performed
within an hour, the machine prevents beverages from being
dispensed.
To perform the washing cycles, follow the steps on the
next pages.
