PROGRAMMING
Programming dosifications
To change the factory set dosages, set the Program/Run toggle switch to the “Program” (right) position.
Depending on the dosage you wish to change (1 cup or 2 cups), fill the filter-holder with the proper amount
of ground coffee and place in the group head infusion unit of the machine. Press the corresponding dosage
push-button and hold for approximately 3 seconds. The brew light will be flashing. Once the desired amount
of coffee is achieved press any of the dosage push-buttons to save the new setting in memory. Return the
“Run/Program” switch lever to the “Run” (left) position.
NOTES:1. This operation must be repeated for each dosage you wish to reprogram.
2. The push-buttons which were not reprogrammed will continue using the previous dosage
sets.
3. The “Continuous dosage” is not programmable.
Pre-infusion programming
Pre-infusion causes a non-programmable amount of brew water to be injected into the bed of coffee at
the beginning of the brew cycle; thus wetting the coffee, this is followed by a short delay, followed by the
programmed amount of dispense.
In order to check whether or not the pre-infusion has been turned on, turn the programming switch (14)
to the “Program” (right) position. If the pilot lamp (F) comes on, pre-infusion is on. To eliminate the pre-
infusion, press the continuous dosage button (E) until the pilot lamp (F) turns off; then return the programming
switch to the “Run” position.
