The filter might be a litter tight and hard to take it out from Portafilter when you want to change
the filter. You can use another filter to pry it out.(see image.1.1).
NOTE:

Making the Espresso
Preparing the Espresso
01. Make sure the steam knob is on “OFF” position.
02. Place pre-warmed cup(s) beneath the Portafilter.
03. Press the single or double button for desired volume.
The default amount of single espresso is approx. 35ml.
The default amount of double espresso is approx. 70ml.
The flavor of your coee will depend on many factors, such as the type of coee beans, degree of roast, freshness,
coarseness or fineness of the grind, dose of ground coee, and tamping pressure. Experiment by adjusting these
factors just one at a time to achieve the taste of your preference.
A cold Portafilter, filter and cup can reduce the extraction temperature enough to significantly aect the quality of
your espresso. We recommend to ran a brewing cycle without coee ground to preheat them before extraction.
01. Remove the Portafilter and fill the filter with coee grounds using the tamp spoon provided with the
machine.
* We recommend 7-9g for single shot and 13-15g for double shot. The amount will vary depending on your
preferences and the coee grounds you used.
02. Tamp the coee grounds with the tamp spoon. The coee grounds must be pressed evenly to obtain a well
levelled and flat surface.
* Remove any coee residue from the edge of the Portafilter.
03. Insert the Portafilter into the brew head with a 45°movement to the left and turn it to the right to lock it in
place. The Portafilter must be perpendicular to the machine or slightly tilted towards the right.

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

Continue as follows
01. Press the steam button. The steam button will start to flash if the temperature is not high enough to make
steam. Once the preheating has finished, the Steam Button will light up.
02. Turn the steam knob slightly counterclockwise to eliminate
any condensation from the wand then turn the knob o again.
(see image.3.1-3.2)
03. Place the jug, half-filled with cold milk, under the steam wand.
04. Place the steam nozzle just below the surface of the milk. If it is inserted too
deep, the milk will not be frothed; if it is not inserted deep enough, big
bubbles will be produced and then disappear immediately.It is important to
keep the Steam Tube not at the centre but close to the edge of the jug, with
an appropriate angle to produce a stronger vortex. (see image.4.1-4.2)

05. Turn the steam knob to position. The steam will come out of the steam wand.
Frothing Milk
8 | [email protected]
To prepare a traditional cappuccino or latte, we recommend:
- using cold, fresh whole milk. The density of the frothed milk will depend on the milk fat content.
- using stainless steel, circular, rounded milk jugs, narrower at the top, with a spout, necessary to make
cappuccino decorations.
Before starting, it is important to slightly move the steam wand outwards in order to insert the jug directly under
it and facilitate the movements required to froth the milk correctly.

The entire operation should last no longer than 3minutes, because the machine will stop
making steam automatically after 3minutes of continuous steaming.
NOTE:

06. Once the desired frothing has been achieved, the steam nozzle must be pushed deeper to heat the milk well.
07. Once the desired result has been achieved, turn the steam knob to “OFF” position to stop dispensing steam
and remove the jug.
08. Press the steam button again to quit the steam mode. Pour the frothed milk into the coee.
09. Turn the steam knob on to eliminate any residue milk from the wand then turn the knob o again.
10. Do not make coee immediately after frothing milk. The temperature of boiler is too high, and the machine
is under the over-heating protection. Under the protection, the single and double button will flash if you
press either of them.
Over-heating Protection
After having used the steam wand and exited the steam function, the machine is under the over-heating
protection. Under the protection, the single and double buttons will flash simultaneously if you press either of
them, indicating that the boiler needs to be cooled o in order to reach the precise espresso brewing temperature.
Please proceed as below 4steps to cool down the machine:
a. Under the over-pressure protection, turn the steam knob to position to make hot water.
b. Let hot water come out from the steam wand to cool down the boiler.
c. Once the temperature of boiler is cool down, all the buttons will fully illuminated.
d. Return knob to the “OFF” position, and the coee machine is ready for the next brew.
To froth the milk correctly, the steam nozzle must always be in contact with the milk and not
with the froth. Therefore, as the layer of froth increases, the jug must be slightly raised trying to
keep the Steam Tube in contact with the milk, without touching the bottom of the jug.
NOTE:
It is advisable to always keep a hand on the rounded part of the jug to feel the temperature
increase of the unfrothed milk.
NOTE:
To make the froth more compact, it is advisable to lightly tap the jug on a flat surface after
frothing.
NOTE:
WARNING The steam wand may be very hot during and after use. To avoid burns, move it only by
placing your fingers on the rubber tip fitted on the steam wand.

Set the volume of single shot:
01. Keep pressing the single button for 3seconds, the machine will beep 3times quickly and start to brewing.
02. Press single button again once desired volume of espresso has been extracted. The machine will beep 3
times slowly to indicate the new volume of single shot has been set.
