CONTROL PANEL AND COFFEE SELECTION

BEFORE FIRST USE 

Before the first use, follow the steps below to rinse and 

preheat the appliance. 

1.  Check and ensure that all accessories are free of damage 

and not missing.

2. Fill the water tank with clean water. The water level should 

not exceed the MAX position. When using for the first time, 

first remove the rubber plug at the bottom of the water 

tank.

3. Align the portafilter with the portafilter bracket (no coffee 

should be placed in the portafilter at this time). Rotate 

the portafilter counterclockwise to lock it in place (place a 

Single-Cup or Double-Cup filter in as needed).

4. Place a cup on the drip plate and plug in the appliance. 

Press the   button. The appliance will start preheating. 

After preheating, the appliance will enter into standby 

mode.

5. Turn the knob to the   position, after a while, steam will 

flow out of the steam tube. The steam tube should be 

aligned with the drip tray.  

6. Press the   or   buttons to rinse the pipes in the appliance. 

Make sure to have a cup on the drip tray to collect the water 

and avoid scalding.

NOTE: 

Do not get close to the portafilter or steam tube to 

avoid scalding when the appliance is brewing hot water.

7. After water stops dispensing, empty the water in the drip 

tray and cup.

8. Thoroughly clean the detachable parts of the entire 

appliance with warm water.

CHOOSING THE RIGHT COFFEE 

GRINDS

Coffee Grinds

The coffee should be freshly ground and subjected to deep 

roasting. You may need to use French or espresso roasted 

coffee beans for espresso coffee. Pre-ground coffee will keep 

its aroma for 7 to 8 days. Coffee stored in a sealed container 

placed in a cool place may retain its aroma longer. Do not 

store ground coffee in the refrigerator or freezer. When coffee 

beans are freshly ground, they will better retain their aroma 

and provide higher quality coffee.

Grind

When making espresso, grinding the beans is a key step and 

can take some practice to master.

 

– The correct grind should look like salt.

 

– If the beans are too finely ground, it may cause the coffee 

to flow intermittently or fail to brew coffee.

 

– If the grind is too coarse, the water will flow through the 

coffee too quickly, which will affect the aroma and taste of 

the extracted coffee.

 

– You can adjust the coarseness of the ground coffee by 

rotating the coffee bean hopper. The grinding position 

necessary will vary depending on the type and quality of 

the coffee beans you use, so you need to make appropriate 

adjustments with each new bean used to achieve the best 

results.

 

– For freshly-roasted coffee beans (within 1 month), the 

grinding position should be set between 5–10. The Double-

Cup (Grind) setting can produce about 0.67 oz (19 g) of 

coffee and the Single-Cup (Grind) setting can produce 

about 0.46 oz (13 g), creating a relatively good coffee 

extraction.

 

– To avoid creating moisture in the coffee bean hopper and 

affecting the grinding and the final coffee taste, do not 

overfill the bean hopper.

To obtain uniform and consistent coffee grinds and make 

a cup of high-quality coffee, be sure to adjust the grinding 

setting according to the type and quality of the coffee 

beans.
