BREWER UNIT CLEANING CYCLE
As well as manual cleaning through setting in the “Maintenance” menu, anyway performed without
“Serving”, an automatic cleaning cycle can be set.
After a selection, if a new “Serving” is not detected within 20 seconds, a cleaning cycle is carried out and the
vending machine will be out of service for approximately 60 seconds.
Manual cleaning must be carried out every time new “Servings” are loaded; it is however advisable to leave
the automatic cycle control set at all times.
CHECKING AND ADJUSTING THE COFFEE DISPENSING PARAMETER SETTINGS
In order to get the best possible quality for the dispensed products, the vending machine was adjusted to
the optimum setting at the factory; however in relation to the products used it is advisable to check the
following points:
The water dose, which must be between 35 and 40 cc.
The coffee dispensing temperature, which must be between 78° e 85° C.
The pump by-pass valve setting, adjusted to 10 bar by default.
The dispensing time, which must be between 18 and 20 seconds, considering that a longer time (with the same water
dose) could to clog filters, and a shorter time could alter the by-pass setting towards a higher pressure, and lead to
poorer dispensing quality.
STANDARD SETTINGS
By default the vending machine is adjusted at the factory as follows:
Coffee temperature at the spout, 78-85° C
Instant boiler temperature, 78-82° C
Dispensing time, 18 to 20 seconds
Coffee water dose, 35 to 40 cc
ADJUSTING THE INSTANT BOILER WATER TEMPERATURE
The instant boiler has a dual function: it provides hot water for all instant products by means of its two-way
solenoid valve.
It pre-heats water for the flow-through boiler to avoid the scaling problem typical of such type of boiler.
It is therefore important to have an optimum setting, as a temperature change affects also the final
temperature of the coffee.
To change such temperature the special trimmer on the machine board must be used.
Considering that:
Tightening (clockwise) will increase the temperature
Loosening (anticlockwise) will decrease the temperature
Each complete turn correspond to +/- 0.5° C change
BOILER OVERHEATING PROTECTIONS
The boilers are fitted with safety overheating protections.
The espresso boiler is fitted with two thermo-fuses located above it and sheathed in a special silicone tube.
In the event of failure that could cause boiler overheating, the two thermo-fuses melt, thus disconnecting
the power from the heating element.
After the occurrence of such melting, the problem that caused the malfunction must be identified, corrected
and BOTH THERMO-FUSES MUST BE REPLACED with identical ones or having the same characteristics.
Fuses must never be replaced with others that are not approved by the manufacturer, otherwise hazard
conditions could be created and the manufacturer declines all responsibility.
The instant boiler is fitted with manual reset overheating protection; therefore after having identified and
corrected the cause it is sufficient to press the upper red button to restore the initial conditions.
