Steam Making Method

Note: During steam production, if need stop the steam output, just turn the 

knob back to the preheating and cooling state.

When the power indicator “     ” and coffee indicator “     ” are always on, can 

enter the steam selection mode. Turn the knob to steam making status “     ” 

position, the boiler continues to heat, and the coffee light flashes white and 

red alternately. After heating to the steam set point, the coffee light (red 

light) is always on,enter the milk foaming mode,the maximum time for 

foaming milk is 120s.

Note: The cup with milk needs to be placed at the steam pipe outlet 

immediately after the red light is always on.

1.After steam preheating done, rotate the knob to steam making “     ” 

position, if you need to stop steam production halfway, just rotate the knob 

directly back to the preheating and cooling state.At this time, after 5S, the 

system automatically pumps water at full speed to the preheat spot of 

brewing coffee according to the temperature rise detection; No need to 

pump water if below the preheat spot of brewing coffee. If need make 

steam, just repeat the steam production procedure again, rotate the knob to 

the steam making “     ” state, which can make steam. During steam 

production, the power indicator “     ” and coffee indicator “     ” (red light) 

are always on, and the boiler and water pump perform corresponding 

actions according to the procedure. After milk foaming, need clean the 

foaming device, steam pipe foaming nozzle in time to avoid milk scaling to 

block the foaming nozzle and air inlet of the foaming device.

Caution

2. Exit steam mode
A.Rotate the knob to steam preheating “     ” state, after 5S, the system 

automatically pumps water at full speed to the preheat spot of brewing 

coffee according to the temperature rise detection; no need to pump water 

if below the preheat spot of brewing coffee. Avoid over high and over low 

temperature coffee during coffee brewing; Enter the coffee preheating cycle 

mode.(The indicator light is always on when cooling state).
B.Turn the knob to the standby “     ” mode, enter the brewing coffee 

standby mode directly.

Note: This operation may affect the coffee temperature and the effect.

During brewing coffee--- please pay attention to the following problems to 

avoid scalding and powder frying:

1.In the normal coffee brewing process, do not open the coffee box (handle) 

immediately after brewing, need turn the knob to the preheating and cooling 

state position “     ” before open --- take away the coffee cup first, and then 

unscrew the coffee handle.
2. After the steam is finished, do not make coffee immediately. 10s later, brew 

coffee again (if the steam making time is too long, please cool the boiler twice 

more --- that is, let the machine pump water automatically for cooling --- 

see “steam making” for details).

3.During operation, pay attention to the water level in the water tank , avoid 

draining the water in the water tank and let the water pump form a vacuum, 

which makes it difficult for the machine to pump water --- if this problem 

occurs  (if  it  is  difficult  to  pump  water,  turn  the  knob  to  the  preheating  and 

cooling position “     ” for many times or put in/ take out the water tank for 

many times and continuously, to let the water pump discharge the air and 

avoid the problem of back pressure).

4.Coffee temperature: Extraction require water temperature 90-93℃; the cup 

temperature 73.0---82.0℃; Steam production time should not be too long--- 

Prevent  excessive  milk  temperature  from  affecting  the  effect  of  preparing 

coffee.

Note: In order to make the next coffee making more cleaner and purer, it is 

necessary to clean the coffee powder residue and coffee residue in the outlet 

head regularly!!!

The lower end of the 

outlet head ---need 

clean the coffee residue
