Setting the coffee water temperature (flow-through boiler)
The optimum temperature is set at the factory; should any
adjustments and small changes be necessary, proceed as
follows: Check the upper flow-through boiler temperature, which
must be between 94° and 97° C. This way the dispensing
temperature will be 78° to 84° C.
Such temperature must be considered as optimum.
If that is not the case, adjust the temperature using the trimmer
1
on the electronic board located at the back of the cabinet next
to the machine board.
It must be taken into account that:
Tightening will decrease the temperature
Loosening will increase the temperature
Make very small adjustments and check the dispensing
temperature. The instant boiler inlet water temperature is
determined by the instant boiler temperature, as pre-heated
water is sent to the flow-through boiler to reduce to a minimum
the scaling problem typical of such boilers. For adjustments to
the instant boiler see paragraph
Boilers
.
ADJUSTING THE POD HOLDER CLOSURE
In order to dispense a perfect coffee with the pod brewer it is
very important to have a perfect setting on the closing position.
The system is adjusted to the optimum setting at the factory,
however in the event of disassembly for cleaning and/or
replacing filters and gaskets it may be necessary to readjust the
settings; in this case proceed as follows:
To increase tightness between gasket
1
and filter
2
rotate the
pin clockwise using an 11 mm spanner.
To decrease tightness in the case of excessive interference the
pin must be rotated anticlockwise.
After the adjustment, the system is self-locking.
PERIODIC CLEANING OF THE FLOW-THROUGH
BOILER
At least once a year, or not later than 10000 selections, the
flow-through boiler must be cleaned and if necessary descaled;
at the same time the sealing gasket must be replaced.
In order to remove the boiler it is advisable to extract the brewer
unit from the machine.
Before any operations the vending machine must be
disconnected from the power supply, and the unit must cool
down completely. Disconnect the hydraulic circuits, disconnect
the electrical connectors, completely undo the fastening screws
and remove the unit from the machine. Remove the two
securing keys from the upper boiler.
Proceed to cleaning, descaling and any replacement of worn components; thoroughly rinse and reassemble in the
reverse order of disassembly.
