Before First Use

Cleaning The Appliance

• Carefully remove the appliance from the packaging and remove all packaging materials.
• Remove all accessories from the packaging and from the appliance.
• Remove the water tank.
• Clean the water tank with lid, the milk reservoir with lid, the measuring spoon and the filters as well as the filter holder with warm water and some mild dish-washing liquid. After that, rinse with clear water and dry.
• Also, wipe the body of the espresso machine and the drip tray and grid with a soft, damp cloth and dry all parts.
• Make sure that the milk reservoir is assembled well.

NOTE:

The filter holder and filters are not dishwasher safe.

Initial Use

1. Fill the water tank and the milk reservoir with cold water up to the MAX line.

2. Insert the plug into a wall outlet with a suitable voltage (120V~, 60Hz).

3. Press the Power button, the Power indicator light turns on and the coffee machine starts to preheat automatically. Once the preheating is finished, all the buttons will light up continuously. This preheating process takes about 2 minutes.

4. Place a cup under the brew head. Tum the milk knob and point at the cup. Press and hold the Latte button for 3 seconds. The machine will start to make hot water from the milk tube. Let the hot water flow out of the milk tube for about 8 seconds, then press the Latte button again to stop. This process allows the water to flow into the empty pump for the first use.
   NOTE:
   There will be a loud noise and a little shake when the machine runs for the first time. It’s normal for a 20-bar pump. The noise will decrease with use.

5. Insert the Filter into the Filter holder

6. Insert the fi.lter holder without coffee grounds into the brew head with a 45° movement to the left and tum it to the right to lock it in place.
   The filter holder must be perpendicular to the machine or slightly tilted towards the right. (see image.1)

7. Place an empty cup under the filter holder and press the Espresso button once to brew.

8. After the brewing cycle has finished, pour the water out.
   Now your coffee machine is ready for use.

Preparing the Espresso

Using a cold filter holder, cold filter or cold cup(s) can reduce the extraction temperature enough that it significantly affects the quality of your espresso. We recommend running a brewing cycle without coffee grounds to preheat them before brewing(see steps 5-8 of Initial Use).

Select the filter to be used as follows: (see image.2)

• For a single shot: use the shot filter.
• For a double shot or two single shots: use a double shot filter.
• Insert the filter into the filter holder.
• To insert the selected filter into the filter holder, press the filter down into the filter holder. (see image.3)
•  The filter might be difficult to remove from the holder when you want to change the filter. You can use another filter to pry it out(as shown). (see image.4)
• Fill the filter with coffee grounds using the tamp spoon provided by the machine.
• We recommend 7-9g for single shots and 13-15g for double shots. The amount will vary depending on your preferences and the coffee grounds you use.
• Tamp the coffee grounds with the tamper. The coffee grounds must be pressed evenly to obtain a well levelled and flat surface.
• Remove any coffee residue from the edge of the filter holder.
• Insert the filter holder into the brew head with a 45°movement to the left and turn it to the right to lock it in place. The filter holder must be perpendicular to the machine or slightly tilted towards the right.

Making the Espresso

1. Place pre-warmed cup(s) beneath the filter holder.

2. Press the Espresso button once for a single shot. The Espresso button will flash in blue when brewing.

3. Press the Espresso button twice for double shots. The Espresso button will flash in green when brewing.

4. The machine will start brewing the espresso according to your selection. The machine will turn off automatically and the button will become solid indicating that the cycle has been completed.
   Your delicious espresso is ready to be enjoyed.

   • The flavor of your coffee will depend on many factors, such as the type of coffee beans, degree of roast, freshness, coarseness or fineness of the grind, amount of ground coffee used, and tamping pressure. Experiment by adjusting these factors just one at a time to achieve the taste of your preference.

NOTE:

There will be noise during the operating process. This is normal for a 20-bar pump.

NOTE:

To brew less coffee than the preset serving, press the Espresso button to stop the brewing process when the amount of coffee desired is reached.

Espresso Pressure Gauge

The gauge needle indicates the extraction pressure.

Ideal Espresso Zone

When it is positioned anywhere in the espresso range during extraction, it means the espresso has been extracted at the ideal pressure. (see image.5)

Low-pressure zone
When the gauge needle is under the espresso range zone during extraction, this indicates the espresso has been extracted with insufficient pressure. This can happen when the water flows through the ground coffee is too fast, resulting in an under-extracted espresso that is watery, clod, and lacks crema and flavor. Possible causes for under-extraction include: the grind being too coarse, insufficient coffee in the filter, insufficient tamping, or a combination of any of these. (see image.6)

To resolve this:

1. Select a fi.ner grind setting and retry.
2. Increase the amount of coffee grounds and retry.
3. Increase the tamping pressure and retry.

High-pressure zone
When the gauge needle is above the espresso range zone during extraction, this indicates the espresso has been extracted with too much pressure. This can happen when the water flow through the ground coffee is too slow and results in an over-extracted espresso that is very dark and bitter with a mottled and uneven crema. Possible causes for over-extraction include: the grind being too fine, too much ground coffee in the filter, tamping or a combination of any of these. (see image.7)

To resolve this:

1. Select a coarser grind setting and retry.
2. Decrease the amount of coffee grounds and retry.
3. Decrease the tamping pressure and retry.

Discard the remaining water by removing the water tank and turning it upside down over the sink. It is recommended to empty the water tank between uses. Wash the water tank with soapy water, rinse it well, and wipe it dry.

Descaling

To make sure your coffee maker operates efficiently, to clean the internal pipes, and to preserve the flavor of your coffee, the coffee machine needs to be descaled, cleaned, and maintained periodically. Also, after 500 brew cycles, a descaling warning will be shown. The Power button will flash 5 times to indicate it is time to descale the machine. The descaling warning will appear at every start-up if you do not run a descaling cycle.
However, the frequency of cleaning depends upon the hardness of the water used. The following table gives the suggested cleaning intervals.

Descaling the machine::

1. Mix the water with a descaling agent( 4 parts water to 1 part descaling agent) and fi.ll the water tank up to the Max marking.
   NOTE: Please also refer to the instructions on the descaling agent. Please use a household descaling agent, or you can use citric acid instead of a commercial descaling agent- in this case use 100 parts of water to three parts of citric acid.

2. Place an empty cup or other suitable receptacle on the drip tray.

3. Press and hold the Cappuccino and Latte buttons together for 5 seconds. The machine will start the descaling cycle, and the descaling cycle will run 6 minutes then stop automatically. (see image.17)
