First time machine start-up
Once the machine has been properly installed:
* Turn on the water supply.
* The coffee boiler(s) will automatically begin to fill.
* Locate the group caps and loosen the bleed screw 1/4 turn until a water bead is visible.
Once a water bead is visible, re-tighten the bleed screw snugly.
* Once the groups have been bled, turn the main power switch to the FILL position. Within 6
seconds, the rear (steam) boiler will automatically begin to fill .
* Once the rear (steam) boiler has filled, (check the sight glass to ensure the rear boiler has
filled to the appropriate level, between 2/3 - 3/4 full), turn the main power switch to
the RUN position.
* While the boilers are heating, press any dispense switch and ensure the pump pressure
(bottom scale of the gauge) reads 9 bar while dispensing. Adjust if necessary.
* Wait for the boilers to heat fully indicated by the coffee boiler heating light going off and the
top scale of the pressure gauge reaching 1.2 - 1.5 bars.
Pre-infusion
Pre-infusion is the dampening of the coffee grounds allowing them to expand in the portafilter prior
to the actual brewing process beginning. This seems to improve the coffee flavor of single shots.
To program the machine to pre-infuse, perform the following:
* Turn the main power switch to the OFF position.
* While holding the
far left
(single ristretto) button on the left most keypad turn the power
switch to FILL.
* The light above the “Swirl” button will illuminate indicating that the control box has received
the pre-infusion command.
To disable pre-infusion, perform the following:
* Turn the main power switch to the OFF position.
* While holding the
second
button on the left most keypad turn the power switch to the FILL
position.
* The light above the “Swirl” button will illuminate indicating that the control box has received
the pre-infusion command.
Programming
* Using the left most keypad, depress and hold the continuous pour (swirl) button for about 5
seconds.
* Once all of the lights on the keypads begin blinking press the button you wish to program.
* Once the desired volume has been reached, (measure from the bottom of the crema),
push the button again.
* Repeat this procedure for each button.
*
Any programming performed on the left group will carry over to all of the groups to the
right. After programming the left group, verify that groups to the right are dispens
-ing the proper volume. You can also individually program the right groups without
affecting the others.
