EGRO 55 SERIES TECHNICAL MANUAL 6.1 CALIBRATING MACHINE TO BEANS - DIALING IN 10 GRAMS PLEASE NOTE: This step requires you enter programming. Please refer to section 3 of this manual for guidance in how to enter programming and how to navigate in the programming mode. This step is critical to the proper function of the Egro 55 series machines. It gives the machine an accurate starting point to produce all drinks. It is unique to the roast of espresso or coffee beans.
EGRO 55 SERIES TECHNICAL MANUAL 6.1 CALIBRATING MACHINE TO BEANS - DIALING IN 10 GRAMS - CONTINUED 1 OPERATING MODES 7 4. You have accessed the Grinders submenu. There are four options in the grinder menu, they are described in the diagram above. 5. Place an empty clean paper cup or light container on your gram scale and tare the scale. 6. Scroll (using the number 5 button) to the Grinder L test? 7. Remove the screw holding front door in place and swing the door open. 8. GRINDER LEFT TEST 8.
EGRO 55 SERIES TECHNICAL MANUAL 6.2 ADJUSTING THE GRIND This is the first step in calibrating the machine to the roast of bean which is being served. This will need to be done using the beans that will be served. 1 TIP: Pull a shot first and see how machine is pouring prior to adjusting the grind. STEPS FOR ADJUSTING GRINDER WITHOUT GRINDER ADJUSTMENTS INSTALLED 1. Remove the screw holding the front door closed. Swing the door open. 2. Find the grinders on the inside of the machine.
