1IMPORTANT SAFETY ADVICES 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, OPERATION AND MAINTENANCE OF THIS DEVICE.
The present manual of Operating Instructions, placed on the device in the packing and supplied with the Technical
Handbook, the CE conformity certification and the electrical tests schedule, is an integral part of the batch freezer
(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 informations 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.
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 THE ASSISTANCE SERVICE OR BY TECHNICALLY AUTHORISED PERSONNEL.
Always unplug the device before undertaking any operation requiring access to the device’s moving parts (beater,
cylinder or extraction door).
Any modification of the electric supply must be exclusively performed by qualified and certified personnel.
Any use of the device that is not for the production of ice- cream, ice- cream cakes or slush, has 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.
Modifying, or attempting to modify this device, can be dangerous and would void any type of warranty.
Always use original spare parts.
It is important to adopt the following precautions to avoid damages to the cylinder, to the beater or any
other mechanical part:
- Do not drop them and do not expose them to bumps;
- do not operate the refrigerator when the beater is not in the cylinder;
- do not operate the device dry, with a bad quality of mixture or in a quantity lower or higher than that one
recommended: the liquids in the cylinder, in addition to the lubrication of its surface, keep the beater cool,
uniforming its temperature.
- The beater and the cylinder are disposal built and paired with precision: for this reason they are very sensible to
temperature changes, that may cause eventual damages to the mechanical parts of the device. NEVER expose to
abrupt temperature changes the parts subject to refrigeration: DO NOT pour water (hot or cold) in the cylinder
immediately after ice- cream has been produced.
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;
- carry out the draining and/or recycling according to the local provisions of the law currently in force on this matter.

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.
2.2 Extraction door's grill
A fixed protection grill [3] prevents, as far as possible, fingers or objects from being
ACCIDENTALLY inserted in the extraction pipe. In order to insure normal operation it
is not possible to adjust the fixed grill as to prevent fingers and objects from being
VOLUNTARILY inserted through the extraction pipe (according to Machines Directive 89/392/CEE and ensuing modifications, Appendix I, Art. 1.1.2.b, 3
graph).
RESIDUAL HAZARD: DO NOT FOR ANY REASON INSERT
FINGERS OR OBJECTS THROUGH THE GRILL OF THE EX
TRACTION DOOR WHEN THE MACHINE IS IN FUNCTION.
The user is warned of the above RESIDUAL HAZARD (89/392/CEE and ensuing
modifications, Appendix. 1, Art. 1.1.2.b, 3
affixed next to the extraction door.
rd
paragraph and 1.7.2) by a label [30]
DO NOT HANDLE OR REMOVE THE GRILL [3] FROM ITS
SEATING IN THE EXTRACTION DOOR!
