• Preheat the portafilter by placing underneath the group head. Rinse with hot water from the group head by holding down the double shot button on the front, right hand side of the machine. Dry the portafilter thoroughly before use. Unlike the Dual Wall Filters, the Single Wall Filters have no markings on the underside of the filter. • Place the portafilter into the grinding cradle • Press the FILTER SIZE button according to the filter size (single shot or double shot) you select. STEP 4 - ADJUSTING THE GRIND SIZE • When setting the grind size it should be fine but not too fine or powdery. The grind will effect the rate at which the water flows through the ground espresso in the filter and therefore the taste of the espresso. • If the grind is too fine (looks like powder and feels like flour when rubbed between fingers), the water will not flow through the ground espresso even when under pressure. The resulting espresso will be over extracted, too dark and bitter, with a mottled and uneven crema on top. • If the grind is too coarse the water will flow through the ground espresso too quickly. This will result in an under-extracted espresso lacking in flavor and without the thick crema on the top. STEP 5 - ADJUSTING THE GRIND AMOUNT • When grinding for a Single Wall Filter using a finer espresso grind, you will need to increase the grind amount to ensure the filter is correctly filled. • To increase the grind amount, turn the GRIND AMOUNT dial beyond the DUAL WALL setting to obtain the correct amount of ground espresso. Note: You may need to try step 4 and 5 a few times, slightly adjusting the GRIND SIZE and GRIND AMOUNT dials each time until you reach your desired combination. STEP 6 - GRINDING THE BEANS • Fill the hopper with fresh coffee beans. • Ensure the portafilter is inserted into the grinding cradle. • Ensure the FILTER SIZE button reflects the filter size inserted in the portafilter. • For Auto Start and Stop Grinding - push the portafilter in once to activate the grinding switch, then allow the portafilter to be filled with fresh ground espresso. Note: To stop the auto grinding midway through a grinding cycle, push the portafilter in once, or press the FILTER SIZE button. • For manual grinding - push and hold the portafilter in until the desired amount of ground espresso has been delivered. 57

STEP 5 – ADJUSTING THE GRIND AMOUNT
• When grinding for a Single Wall Filter using a finer espresso grind,
you will need to increase the grind amount to ensure the filter is correct-
ly filled.
• To increase the grind amount, turn the GRIND AMOUNT dial beyond
the DUAL WALL setting to obtain the correct amount of ground espresso.

You may need to try step 4 and 5 a few times, slightly adjusting
the GRIND SIZE and GRIND AMOUNT dials each time until you reach your desired com-
bination.
STEP 6 – GRINDING THE BEANS
• Fill the hopper with fresh coffee beans.
• Ensure the
