2. Remove all accessories from the packaging and from the unit.
3. Remove the water tank.

the filters and the filter holder in a mixture of mild detergent and water. Rinse and
dry each thoroughly and place them back into the unit.
5. Wipe the body of the coffee machine and the drip tray and grid with a soft, damp
cloth and dry all parts.
6. Make sure that the milk reservoir is assembled well.
1. Fill the water tank and the milk reservoir
with cold water up to the “MAX” line of the tank.

5. Plug the appliance into the appropriate outlet.
4. Adjust the hot water outlet position, turn it point at the cup.
6. Press the Power button, all the indicators flash and the coffee machine starts to
preheat automatically. Once the preheating is finished, all the indicators will light
up continuously. This preheating process takes about 2 minutes.
3. Place the filter holder without coffee grounds into the brew head ensuring it is
properly locked. The filter holder must be perpendicular to the machine or slightly
tilted towards the right.

There will be a loud noise and little shake when the machine
running first time. It's normal for a 20bar pump. The noise will
be weak in the future using.
HOW TO USE
8
7. Place an empty cup under the brew head. Turn the milk knob 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.
8. Dispose of the water in the cup and place it back in the unit, and press the
Espresso button once to brew.
9. After the brewing cycle has finished, pour the water out.
Now your espresso coffee machine is ready to use.
Note:
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 to run a brewing cycle without coffee grounds to preheat them before
brewing (see steps 5-8 of Initial Use).
PREPARING THE ESPRESSO
hold for
3sec.

HOW TO USE
9
1. Select the filter to be used as follows:
FOR A SINGLE SHOT – use the filter for a single shot of espresso if using
ground coffee, or use the E.S.E. filter if using E.S.E. (Easy Serving Espresso)
pods.
2. Remove the filter holder and fill the filter with coffee grounds using the measure
scoop provided with the machine.
3. Using the tamping part of the measure scoop, push the coffee grounds down
wards as far as the tamper will go to. The coffee grounds must be pressed
evenly to obtain a well levelled and flat surface.
FOR A DOUBLE SHOT OR TWO SINGLE SHOTS – use the filter for a double shot
of espresso. By placing two small cups underneath the filter holder, you may
prepare two single shots of espresso at once.
We recommend 7-9g for single shot and 13-15g for double
shot. The amount will vary depending on your preferences
and the coffee grounds you used.
Tip:
Clean any excess coffee from the rim of the filter holder to
ensure proper fit under brew head.
Note:
E.S.E

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, dose of ground coffee,
and tamping pressure. Experiment by adjusting these factors
just one at a time to achieve the taste of your preference.
