1. Fill water reservoir to "MAX" level.
2. Fill milk reservoir to "Max Fill" level and slide it firmly in place.
3. Select a filter and place it on the porta-filter. Place the porta-filter in the unit, locked, and a cup under it. Ensure the frothing tube is pointing inside the cup.

Selecting the Right Cup

Before preparing your beverage, select the right cup size according to the following table:

Selecting the Right Coffee

The Coffee

Coffee should be freshly ground and dark roasted. French or Italian roast ground for espresso is recommended. Pre-ground coffee retains flavor for 7-8 days in an airtight container in a cool, dark area. Whole beans are recommended to be ground just before use. Coffee beans in an airtight container keep flavor for up to 4 weeks.

The Grind

This is a vital step if you are grinding your own coffee. The coffee must be of a fine grind.

• The correct grind should look like salt.
• If the grind is too fine (like powder/flour), water will not flow through under pressure.
• If the grind is too coarse, water flows too fast, preventing full-flavored extraction.

Use a quality grinder for uniform consistency.

Operating Instructions

Filling the Water Reservoir

1. Fill the reservoir with water (do not exceed "MAX" line, do not use warm/hot water). You can use a jar or remove the reservoir to fill.
2. Close the water reservoir lid and place it back tightly in the unit.

Filling the Milk Reservoir

If preparing cappuccino or latte, remove the milk reservoir, open the lid, and pour cold milk (do not exceed "Max" level). Place the milk reservoir back tightly. Cappuccino and Latte buttons will illuminate or pulse.

Choosing the Filter

• For a Single Shot: Use the filter for a single shot of espresso.

2. Turn the filter to the left or right to lock in place.

Filling with Coffee

1. Fill the filter with fresh, fine ground espresso coffee (do not overfill).
2. Tamp and compress firmly and evenly ground coffee. Coffee should be 3mm below top of filter after tamping.
