9 ADJUSTING THE FUNCTIONS
ATTENTION: some machine
functions (temperature, language,
etc.) must be adjusted by a
specialised and authorised
technician, while the machine is
operating and with the utmost care;
these operations are described in
the relevant technical manual.
9.1 ADJUSTING THE GRINDER DOSER
Install, adjust and prepare the
grinder doser as described in the
relevant instruction manual.
9.2 TESTING COFFEE DISPENSING
Dispense coffee several times following the
instructions in the relevant chapter and check the
quality of the coffee.
- Dispense the coffee and check that 20-30 cc of
coffee are dispensed in 20-30 seconds.
- If this is not the case, the coarseness of the coffee
must be adjusted on the grinder doser, finer
grinding increases brewing time, coarser grinding
reduces brewing time.
- Make sure that the coffee dispensed has the
following characteristics:
• hazelnut-colour cream
• consistency (fine bubbles)
• cream lasting more than 1 minute
These indications are not binding as
the correct quantity and therefore
the quality of coffee depends on the
type of coffee, type of water and
climatic conditions.
9.3 FINAL DELIVERY
At the end of machine installation, it is necessary to:
- Train the personnel who will use the machine,
preparing a number of test coffees, cappuccinos,
etc.
- Explain how to perform maintenance and cleaning
operations to ensure correct care of the machine.
- At the end of installation, fill in the installation
report.
