Operation of the machine
Press the "RESET" pushbutton 1 to operate the machine and ensure that all the motors can be started up.
Press pushbuttons 3 (pump), 5 (stirrer) and 6 (fridge compressor) to start the relative motors. When the
pushbuttons light up, this means the relative motor has started; when the lights are off, this means the
relative motors are stopped.
Caution: pushbutton 3 (pump) can be on or off as required irrespective of the others.
pushbutton 5 is not pressed (stirrer), the fridge compressor (pushbutton 6) will not operate.
Adjusting the pump
To regulate the production of the machine, increases or decreases the speed of the pumps (and hence, the
production of ice cream now) with the handwheel black (pos. T p. 15) placed on the front of the machine.
The pump is displayed by the display of the flow rate 4 L / h and the production of ice cream with 100%
overrun.
(See
The pump flow must be associated with the injection of air into the ice cream to be made manually with the
regulator. See the following pages how.
Display of "viscosity"
-
During operation of the machine, display 7 gives the "viscosity" value for the ice-cream at that particular
moment in time. This numerical value (Ampere), which is low at the start and higher as the ice-cream comes
ready, is only indicative and enables the operator to check that the flow of ice-cream is constant during
production.
The maximum viscosity data is set when the machine is commissioned and if this figure is exceeded
(maximum ice-cream hardness) the ampere system inside display 7 will automatically stop the fridge
compressor for a few seconds and it will then start again once the value returns within normal parameters.
Connection of "hot gas"
-
Press pushbutton 8 to give the go-ahead for injection of hot gas. The quantity of gas injected is adjusted
using the appropriate regulator 9 and display of the viscosity value appears on display 7. Instructions are
given on the following pages.
