EXTRACTION Pushbutton [K7]
Press this button to let the ice- cream goes out from the extraction door. This happens by rapidly rotating the beater
COUNTERCLOCKWISE. The refrigerating system is automatically shut down to avoid the formation of ice.
Note: It is always suggested to wait for the end of the cycle ([Z5] indicator off) or stop the refrigeration by hand using
the REFRIGERATION Pushbutton [K5] before commanding the extraction.
To avoid excessive stress, before commanding the extraction, it is necessary to OPEN THE EXTRAC-
TION DOOR.
The [Z7] indicator signals that the beater is in functioning COUNTERCLOCKWISE.
Press this button once again in order to complete the extraction cycle.
BUZZER Pushbutton [K6]
The device features a buzzer which rings when the processing time has come to an end. To activate it, press this button (the
[Z6] indicator lights up).
Digital display
- When the device is not functioning, the display shows the total refrigerating time
previously set (in prime minutes);
- When the device is in refrigeration cycle, the display shows the residual refrigerating
time and a flashing spot;
- when it shows “oo” (two small squares) it indicates a machine failure:
• the lid is not correctly closed;
• the chute with protection flap is not correctly installed;
• a safety device has come into operation. See Section 10 - Malfunctions.
6.3 Production
In devices with water condensation, check that the condensation water’s faucet is open;
- check that the ON/OFF Pushbutton’s indicator [Z1] is lightened. If not, check that machine is plugged in and Main
Breaker is turned on (on “I”);
- Check the lid is closed and the chute with protection flap is in position, otherwise the device will not operate.
NO “oo” (two small squares) should show on the Display;
- press the ON/OFF Pushbutton [K1].
Do not press the BEATING [K2] or REFRIGERATION [K5] Pushbuttons before having introduced liquids
in the cylinder. The beater must not function dry, otherwise it will be damaged.
- before beginning the production proceed with rinsing, washing and sanitization using a detergent and sanitizing
solution (see Sections 7 PRE- WASHING and 8 WASHING).
