Operating intervals:
•
The manufacturer is not recommending using the grinder continuously for a period of time exceeding 12
minutes (or continuously grinding over 1KG of coffee).
•
It is a normal occurrence that during long grinding periods the grinding chamber will heat up. In order to
achieve best grinding results, it is recommended to grind coffee in short intervals of not more than few
minutes each.
Adjusting coffee grind (Fig 5.2)
•
The Aroma II grinder is equipped with step-less grinding adjustment coupled with a revolutionary encoder
micrometric measurement of the grind setting and LCD display
•
The grinding blades’ distance was factory pre adjusted to satisfy different common coffee grinds from super
fine to extra-coarse. The entire range can be achieved by turning the dial over 13 complete turns.
•
Turning the grinding dial counterclockwise will make the grind finer and turning it clockwise will make the
grind coarser. Along with the dial turning the LCD will show different setting reading. On the table below you
can find the different setting corresponding to different coffee grinding:
LCD reading
Coffee Grind usage
Dial turns
(from most fine position)
1-7
Turkish coffee grinding
Most fine to two turns
8-18
Espresso coffee grinding Two turns to six turns
18-25
Filter and French press
Six to nine turns
Over 25
Coarse grinding usage
Nine to thirteen turns
•
Grind a small amount of coffee and test its coarseness with your espresso machine.
•
As coffee beans’ qualities and characteristics are changing from time to time it is recommended repeating this
adjustment once in a while.
Calibrating the encoder measurement and LCD display (Fig 5.3)
•
As a rule, refrain from changing the grind setting position while the grinder is not connected to the electricity.
In the case you suspect the setting display and the actual setting are misaligned please find below a simple
step by step procedure to calibrate the display reading with the actual grinding setting:
o
Close the beans hopper door, grind empty the grinding chamber (till no more noise of grinding is
coming from the grinder when it is operated)
o
Turn the dial knob counter clock wise (Fine direction) till reaching the knob’s mechanical stop (where
the knob can not turn any further)
o
Insert any kind of 1-2mm diameter pin through the reset hole, and gently press the internal reset
button continuously for over 3 seconds.
o
Re-calibration is done! Now, the grinding setting and the display are aligned.
o
Return the grinding setting back to your previous setting (clock wise), while doing so please note that
the display will immediately change from showing ‘– – ‘ to show ‘01’ after a very minimal turn.
