1IMPORTANT SAFETY SUGGESTIONS AND PRECAUTIONS
CAREFULLY READ THE INSTRUCTIONS CONTAINED IN THE PRESENT OPERATING INSTRUCTIONS MANUAL
BEFORE INSTALLING AND OPERATING THIS DEVICE. THESE INSTRUCTIONS HAVE BEEN DRAFTED FOR
THE SAFETY OF INSTALLATION, OPERATIONAND MAINTENANCE OF THIS DEVICE.
The present manual of Operating Instructions, placed on the device in the packing and supplied with the Technical
Handbook, the EC’s conformity certification and the electrical tests schedule, is an essential part of the mixer (also
defined, in the present manual of operating instructions, simply with the term, device) and must be preserved for any
future consultation.
The technical handbook must always be given, together with the device, to the Assistance Service’s personnel or to the
technicians, to whom you will eventually request assistance.
In case of selling or transferring to other user, all the above mentioned documentation must be handed to the new user,
so that he can be informed of the operation and relative technical information and safety instructions.
RESIDUAL HAZARD: DURING THE HOT AND COLD MIXING CYCLES, THE
PRODUCT BECOMES VERY HOT (+65...+85°C). SERIOUS HEALTH DAMAGE CAN BE CAUSED BY CONTACT WITH THE LID [5], THE TAP [11] AND
THE DEVICE'S SURFACE [35] TOO. WHEN LID IS OPENED THE MACHINE
STOPS, HOWEVER, THE MIXTURE REMAINS VERY HOT.PLEASE FOLLOW THESE RULES:
Always check that the heating and cooling mixing cycles are completed or the
product’s temperature, as shown on the display, is sufficiently low before opening
the lid or the tap.
Pay attention if an electrical power supply failure (or a blackout) occurs during a hot and cold mixing cycle, as the
mixture’s temperature inside the tub could be still very high and the device thermometer would not be able to display it.
If in doubt whether the mixture’s temperature is sufficiently low, do not open the lid or the tap, unless it is absolutely
necessary. Should this occur, wear protective clothing (gloves, overalls, etc.), in order to avoid direct contact with the
product.
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.
THE USER MUST NOT EXECUTE OPERATIONS WHICH ARE NOT CLEARLY CONTAINED IN THE PRESENT
USER’S MANUAL. ANY OPERATION WHICH REQUIRES TOOLS NOT GIVEN IN THE DEVICE’S EQUIPMENT
IS TO BE CARRIED OUT ONLY BY THEASSISTANCE SERVICE OR BY TECHNICALLY AUTHORISED PERSONNEL.
Always unplug the device before undertaking any operation requiring access to the device’s moving parts (i.e. the
beater).
Any modifying of the electrical supply must be exclusively performed by professionally qualified and certified personnel.
Any use of the machine other than heating and cooling mixture is 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.
Modifying, or attempting to modify this device, can be dangerous and would void any type of warranty.
Always use original spare parts.
In the event of the use of the device being no longer required, deactivate the machine by severing the electric cable (after
unplugging it from wall socket). In addition, follow these recommendations:
- avoid dispersing the freezing gas and the oil contained in the device;

2SAFETY DEVICES
DO NOT ALTER THE SAFETY DEVICES AND DO NOT UTILIZE THE MACHINE IF THE SAFETY DEVICES ARE
DAMAGED OR MALFUNCTIONING.
THE MANUFACTURER IS NOT RESPONSIBLE FOR POSSIBLE DAMAGES CAUSED TO PEOPLE OR OBJECTS BY THE ALTERING OR BYPASSING SUCH DEVICES OR RELATIVE 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.
5
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 magnet [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.
3TECHNICAL DATA
3.1 Technical data plate and CE marking
The technical data plate and CE marking must not be removed. It is placed on the back side of the device and identifies:
- the name and address of the manufacturer [1];
- the designation of the model [2];
- the relative serial number [3] and the year of construction [4];
- the values of voltage and frequency [5];
- the type of cooling [6], the power [7] and current [8] consumption;
- the type and quantity of freezing gas contained [9];
- the values of high and low pressure [10] and the CE marking [11].
3.2 Acoustic pressure level
The average equivalent continuous acoustic pressure level of this device is quoted in the Technical Handbook (Technical
Data section). This data has been measured at 1 meter from the surface of the device and at 1.60 meters from groundlevel, during the device’s functioning.

4CARRYING AND UNPACKING
Note: We suggest you to let the Assistance Service or qualified technicians carry out the transportation, unpacking
and installation.
TO LIFT THE DEVICE ALWAYS USE AN ADEQUATE LIFTING DEVICE.
ATTEMPTING TO LIFT IT MANUALLY IS DANGEROUS AND CAN DAMAGE YOUR HEALTH.
The device’s weight specifications, both inclusive of packaging and net, can be found
in both the supplied documents and on the packaging itself.
To prevent the oil contained in the compressor to flow into the refrigerating circuit, it is necessary to
always keep the device in upright position, both during carrying and during the installation and operation. Always follow the instructions on the packing.
4.1 Transportation of the packed device
The packing has been projected to assure at the device the highest protection.
It is therefore suggested to transport the device while it is packed as near as possible
at the place where it will be installed.
To carry the packed device, use an elevator, or a bench trolley, inserting its forks in the
basement’s holes.
4.2 Unpacking
- WOOD PACKING: unnail the top panel, then separate the lateral panels.
- CARDBOARD PACKING; cut the strips and remove the cardboard from the top;
After having opened the packing, make sure the device isn’t damaged. In case of doubt, do not use it, and call the Seller.
THE OPENING OF THE LATERAL PANEL IS ONLY ALLOWED TO THE ASSISTANCE SERVICE OR TO
QUALIFIED TECHNICIANS AND MUST BE MADE BEFORE CONNECTING IT. MAKE SURE NOT TO DAMAGE THE INTERNAL PARTS OF THE DEVICE.
English
Operating instructions
- Remove both the lateral panels unscrewing the relevant fixing screws [21];
- Find and unscrew the bolts [22] which fix the device’s frame at the packing’s basement;
The outlet of the supply cable is placed on the device’s lower side. During the lifting make sure not to
damage it.
- Lift the device from the basement, possibly working on the lower side, near the wheels, and however, only on the
frame’s carrying parts. Remove the basement, and lean the device on the floor avoiding bumps;
DO NOT insert objects, ropes or brackets for the lifting THROUGH the device, since these could damage
the inside parts.
- Re-close the lateral panels;
- Replace or move the packing, which is produced with entirely recyclable materials (
).
