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 ([Z6] indicator off) or stop the refrigeration by hand using the
REFRIGERATION Pushbutton [K6] 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.
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 [K5] or REFRIGERATION [K6] 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).
Note: If you plan to have more than one consecutive production cycle, you can avoid
the washing between a cycle and the other, making sure you begin with the
clearer mixtures.
Before operating beater, ALWAYS check that beater's fixing knob [7] is
FIRMLY TIGHTENED and the gasket is intact and clear of any fat. Should
the knob accidentally coming lost and falling into the cylinder while
operating, this would cause serious damages to the machine.
