anyfuture consultation.
TheTechnical Handbook must always be given, together with the device, to theAssistance Service’s personnel or to
thetechnicians to whomyou will eventually requestassistance.
Incase ofselling or transferringto other user,all the abovementioned documentation mustbe handed to the newuser,
so that he can be informed of the operation and relative technical information and safety instructions.
DO NOT INTRODUCE YOUR FINGERS OR OBJECTS IN THE DEVICE’S LOOPHOLES.
DO NOT REMOVE OR HIDE, FOR ANY REASON, ANY LABEL APPLIED ON THE DEVICE.
NEVER OPEN THE PROTECTING PANELS. THE DEVICE DOES NOT CONTAIN, IN ITS INSIDE, PARTS
WHICH CAN BE OPERATED BY THE USER.
THEUSER MUST NOT EXECUTE OPERATIONS WHICHARE NOT CLEARLYCONTAINED IN THE PRESENT
USER’S MANUAL. ANY OPERATION WHICH REQUIRES TOOLS NOT GIVEN IN THE DEVICE’S EQUIP-
MENT IS TO BE CARRIED OUT ONLY BY THE ASSISTANCE SERVICE OR BY TECHNICALLY AUTHOR-
ISED PERSONNEL.
Always unplug the device before undertaking any operation requiring access to the device’s moving parts (beater,
cylinder or extracting door).
Any modifying of the electrical supply must be exclusively performed by professionally qualified and certified person-
nel.
Any use of the device that is not for the production of ice-cream, ice-cream cake or slush, is to be considered
improper.
Do not connect and/or operate the device when any part is missing, except for specifically mentioned cases.
The device has been made to be operated by adults, prohibit children to play with it.

JECTSBY THEALTERING OR BYPASSING SUCH DEVICES ORRELATIVE CIRCUITS.
2.1 Lid's magnetic sensor
This safety device, featuring an approved type magnet [1] and a magnetic contact [2]
avoids accidents caused by the accidental starting of the beater when the lid is open.
In consequence the device can't operate when the lid is open, and if it is opened
during its functioning the beater immediately stops.
In any case the lid's magnetic sensor MUST NOT be considered a control to be used
for the normal stop of the device.
DURING THE NORMAL USE, THE DEVICE MUST BE STOPPED ONLY
BY USING THE BUTTONS ON THE CONTROL KEYPAD, AND NOT BY
OPENING THE LID.
The magnet [1] and the magnetic contact [2] MUST be assembled as follows: the grooves [3] and the stencilled semicircle
[5] on the bottom of the magneto [1] must coincide with the grooves [4] (marked by a white line down the side) and the
stencilled semicircle [6] on top of the magnetic contact [2]. The device will not work unless all parts have been
correctly assembled in accordance with these instructions.
2.2 Extraction door's grill
Inlarge-sized models,supplied with extractiondoor, a fixedprotection grill[3] prevents,
asfar as possible,fingers or objectsfrom beingACCIDENTALLYinserted inthe chute.
Inorder toinsure normal operationit is notpossible toadjust the fixedgrill as toprevent
fingers and objects from being VOLUNTARILY inserted through the extraction chute
(according to Machines Directive 89/392/CEE and ensuing modifications, Ap-
pendix I, Art. 1.1.2.b, 3rd paragraph).
RESIDUAL HAZARD: DONOT FOR ANY REASON INSERT
FINGERS OR OBJECTS THROUGH THE GRILL OF THE EX-
TRACTION DOOR WHEN THE MACHINE IS IN FUNCTION.

5.4 Connection to the water network (devices with water condensation)
If your device features water condensation, it is necessary to prepare tubes for the feeding and draining of the water.
Do not let water from a TOWER in, unless they have been specifically designed to utilize water from a
tower. Unless otherwise specified, the machine is designed to utilize water from a WELL.
Note: the correct water temperature to operate the machine is specified in the Technical Handbook, Par. “Technical
data”.
The use of below standard tubes and connections may cause water drops, with consequent inconven-
ience for Your laboratory and, if the drop is abundant with squirts, damage the device.
Uselinen-rubber tubesfor water connection,arranged for 15Bar pressures, interposinga valveor a faucet[17]ABOVEthe
delivery pipe; use a 3/4" rubber holder [18], well fixed with a proper band [19] to connect the tubes at the device’s union.
Note: Tubes for the water feeding of households are on the market (ex. dishwashers) which, in addition to being
cheap, feature the requested characteristics and are predisposed with a rubber holder.
The unions are placed on the back panel of the device, they are marked by a plate “H2O” [20] and are labelled with:
IN: INLET of fresh water in the device;
OUT: OUTLET of water used by the device.
Follow the following precautions to avoid damages at the device’s water circuit:
- do not invert the connection of tubes;
- if water in the area presents a high quantity of spur, install a suitable decalcification or filtration device above
the delivery pipe;
- if not otherwise mentioned in the Technical Handbook, the incoming water’s pressure must be compre-
hended between 1.5 and 6 Bar (ideal pressure: 3 Bar). If the pressure in the device is higher, it is necessary to
interpose a pressure limiting device, appropriately regulated, above the delivery pipe.
AVOID CONSTRICTION OR NARROW TURNS OF THE TUBES.
Note: The water outcoming the condensator, though being hot and not drinkable, is not polluted and can be reutilised.
Before storing the device in rooms with a temperature lower to 0°C it is INDISPENSABLE to get rid of the
water in the condensator and in the inlet and outlet pipes. Call the Assistance Service.
5.5 Initial functioning check

THE FATS CONTAINED IN THE ICE-CREAM MIXTURESARE IDEALFOR THE GROWTH OF BACTERIA, WE
RECOMMEND TO WASHAND CLEANWITH THE MAXIMUM CARE EVERYPART INCONTACT WITH PROD-
UCT, WHEN THE USE OF THE DEVICE IS SUSPENDED.
7.1 Simple washing and hygienisation
Note: Duringthe washing, thedevice could become noisier.
- Pour cool water in the cylinder, detergent and disinfecting solutioncompatible with foods,up to 1/4 of its volume;
- Close the lid and press the BEATING Pushbutton [K2] letting the beater functioning for a brief time;
During the washing operations and in particular during the rinsing, it is useless to activate the beating
for long periods. The missing of lubrication could damage the beater or cylinder.
DO NOT function the beater by pressing the REFRIGERATION/WHIPPING Pushbutton [K5] to avoid a
useless activation of the refrigerating plant, which would freeze the water.
Do not function the EXTRACTION Pushbutton [K7] since it would cause a violent upwards leak of the
washing liquid.

7.3 Accurate washing
THESEOPERATIONS MUSTBECARRIED OUT ONLYWITHTHE BEATER
AND THE LID REMOVED FROM THE DEVICE AND WITH THE SOCHET'S
MAIN BREAKER ON “0”.
TAKE CARE NOT TO ALLOW WATER ORANY LIQUID INSIDE THE MA-
CHINE.
Two or 3 times per week and in any case as provided by in force laws, we suggest to wash and clean with extreme care all
parts of the device in direct contact with the product, during which all components which can be disassembled must be
removed from the device (ref. Par. 7.2) and separately washed. Use cool water and a detergent integrated for foods; then
rinse with cool water.

Before reassembling the components, accurately wash the fixed parts of the device:
- the extraction pipe and the safety grill, utilising the featured brush;
- the upper deck and the inside of the cylinder;
- the front panel, with particular attention for the extraction door, the relative frame and the basin support zone.
7.4 Reassembly
THESE OPERATIONS MUST BE CARRIED OUT ONLY AFTER DISCONNECTING MACHINE FROM
MAIN POWER!
- Assembleblades[31]on beater'ssupports[6]partially screwingscrews[36].Blades
willbe subsequently adjusted.
Carefully place beater into the cylinder, taking care to keep it
vertical without dropping it.
- The slot on the beater's hub [27] goes into the shaft clutch [28];
- FIRMLY tighten beater's fixing knob [7];
Before tightening knob [7], always check that the gasket [G] is
in perfect conditions and in place, an that is clear of any fat as
to prevent knob from accidentally coming loose. Should the
knob fall into the cylinder during production cycle, it would
cause serious damage to the machine.
Note: Gaskets must be periodically replaced (ref. Par. 8.1).
- put lid in place, insert pin [25];
- install the chute [9] beneath the extraction door [14], by screwing the knob [16];
- fix basin support [10] on the front panel with knobs [16];

8MAINTENANCE
Themachine requires a verylimited maintenance. Periodically, wesuggest to:
- check the good conditions of the machine's parts (ref. Par. 7.3);
- check that electric power cable is not damaged;
- Try the efficiency of the safety devices (ref. Par. 8.2).
Itis thenuseful tomaintain theexternal panelsclean and thesurrounding area.Dust, paperfragments orother smallobjects
may penetrate in the machine through the ventilation loopholes (in particular if equipped with air condensation and rapidly
compromise its correct functioning.
The inside parts, to which the user MUSTNOT accede, must be checked by theAssistance Service (ref. Par. 8.3)
8.1 Maintenance during the components disassembling

G
G
Checkthe integrity ofgaskets (indicated with[G] in thefigure) and substitutethose that
aredeteriorated.
Use exclusively original, compatible with food, rubber gaskets. The spare bag
containsa complete series ofgaskets approved bythe manufacturer.
To correctly replace the gaskets it is necessary to:
- remove the old gaskets by using a sharp tool, possibly non-metallic, paying attention not to scratch the seating of the
gasketsthemselves;
- clean the seatings and the gaskets from any kind of grease before inserting the new gaskets.
A yearly preventive replacement of all wearing parts and all gaskets is recommended. We suggest you to always keep a
spare supply: to order it, reference to the Spares Section contained in theTechnical Handbook.
8.2 Check of safety devices
Every three months, check that all safety devices on your machine are in perfect working order:
- openthe lid andremove thebeater;
- check that the protection grill [3] is well fixed and not damaged;
- close lid and supply the machine;
- turnbeating on(beater's shaft will start). Thenopen thelid. Provided thatthe lid’smagnetic contactis correctly working,
the beater’s shaft will stop immediately and the Display will show “oo” (two small squares).
If the machine’s functioning is as described, the safety devices are efficient.
THE MACHINE MUST NOT BE USED IF ONE OR MORE OF THE SAFETY DEVICES SHOULD
RESULT DAMAGED OR MALFUNCTIONING!
