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.
