HOWEVER, THE MIXTURE REMAINS VERY HOT. PLEASE FOLLOW
THESE RULES:
Always assure that the heating cycle is complete or the product’s temperature,
(as shown on the display), is sufficiently low before opening the lid or the tap.
Attention, if an electrical power supply failure (or a blackout) occurs during a
heating cycle, 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.

NEVER OPEN THE SIDE OR BACK PANELS. THE DEVICE DOES NOT CONTAIN, IN ITS INSIDE, PARTS
WHICH CAN BE OPERATED OR SERVICED 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 A QUALIFIED SERVICE THECNICIAN.
Always unplug the device before undertaking any operation requiring access to the device’s moving part s (i. e. the
beater).
Any modifying of the electrical supply must be exclusively performed by professional electrician.
Any use of the machine other than heating and cooling mix is considered improper.
Do not connect and/or operate the device when any part is missing, unleas instruted in the operators manual.
The device has been made to be operated by adults, keep away from children.
