Calibrating the frothing level F030
Calibrating the frothing function. The dispenser arm features the control to adjust the
cream consistency.
It is adjusted at the factory for a level that is suitable in most cases. If the customer would
like to change the consistency, open or close the valve for no more than ½ of a turn each
time until the desired quality is achieved.
The air inlet and milk outlet circuit can be calibrated to check that the system is operating
at the optimum levels:
F030 Machine test -> Run the first Output Milk test
. The machine will supply water
through the milk outlet EV for 10 seconds, showing the value in the display in cubic
centimetres.
→
The standard value is within the 85 to 90 cc range.
→
The possible range of values is 65 cc
–
100 cc. A value below 65 cc
might be due to an obstruction or leakage of suction products or due to
a damaged pump that cannot operate at the minimum operating flow
rate. It must be inspected before proceeding with the test.
F030 Machine test
→
Run the Air Input test.
In this case, the test involves measuring
the flow rate of the air conduit, passing water through it and measuring a volume in cubic
centimetres. The desired value is approximately 60% of the value of the first test.
•
For example: for a value of 86 cc:
→
A correct value would be around 51.6 cc. A high value is associated
with excess air and a low value is associated with insufficient
air/obstruction or damage to a point or component in the circuit

Filling the machine with soluble products
Check the expiry dates before filling the machine with any product.
Fill the hoppers with soluble products. Do not overload them if the product is not going to be
used immediately.
To fill the machine with soluble products and coffee beans, lift the machine
´s
top lip.
