which are highlighted in this manual by the wording “CAUTION”; they are related to
the risks of burning, bruising or electrocution when loading and unloading the product,
or when cleaning the machine or using it improperly.
1.3 - Description
1.3.1 - General description
The machine is designed and manufactured specifically to guarantee that:
- all its parts are stable and robustly constructed;
- it is extremely easy to move and re-position, when empty, thanks to its practical
handles;
17
- PROGRAM led: the led (dot on the screen) turns on to indicate that one of the
ten programs is being displayed or is in use for cooking. If none of the dots on
the screen is on, no program is displayed.
5.4 - Program types
To access the touch-screen display function, check that the master switch is set to ON,
that the desired unit of measurement for the temperature has been set (°Celsius or °
Fahrenheit), and make sure that you have filled or added water to the tank up to the

- HEATING ELEMENT led: the led turns on when a cooking cycle is in progress
to indicate that the heating element is on and heating the water. When the
temperature setpoint is reached, the led and the heating element itself both
turn off, and then turn on when required to maintain the water temperature.
5
- the heating is temperature regulated to high precision;
- its working temperature is between 24°C and 99.9°C (75.2°F-199.9°F) with a
precision of +/- 0.2.
1.3.2 - Construction
The machine is made of stainless steel throughout; this ensures that it is hygienic,
unaffected by acid and salt, and highly resistant to rusting.
- The heating unit consists of armoured heating elements located beneath the tank
which transfer their heat to the water in the tank.
- A shut down device when overcurrent or overheating is detected.
1.4 - Intended use
The machine is designed for Sous-Vide (Vacuum-packed) cooking applications with
immersion in water inside a tank.
It is not designed for direct-contact cooking of foods or for any uses other than
cooking food.
1.5 - Improper use
The equipment must only be used for its intended purposes; in particular:
- Do not use the equipment unless it has been properly installed with all its safety
guards in good working order and correctly fitted, to avoid the risk of serious injury.
- Do not access any of the electrical components without first disconnecting the
equipment from the mains power supply: otherwise you risk electric shock.
- Do not start up the equipment if it has a fault.
- Before using the equipment, make sure that any potentially hazardous conditions
have been properly eliminated. If you notice anything unusual in its operation, shut
down the equipment and inform the maintenance supervisors.
- Do not allow any unauthorised personnel to try to resolve the problem with the
equipment.
Emergency response to injury by electric shock consists first of all in breaking the
injured person's contact with the live equipment (because they will probably have lost
consciousness). This is highly hazardous.
In this instance, the injured person is also a live electrical conductor; touching them
directly would mean suffering electric shock.
It would be better to disconnect the mains power supply, or if this is not possible,
move the injured person away using non-conductive materials (a rod made of wood or
PVC, fabric, leather, etc.).
First-aid medical assistance should be provided promptly and the injured person
should be taken to hospital.

1.6 - Specific equipment details
Giving precise details of the "Model", "Serial number" and "Year of manufacture" of
the equipment will allow our technical service staff to provide you with a more rapid
response.
You must cite the model of the machine and its serial number whenever you contact
technical service.
This information is given on the nameplate shown in Fig. 1.
1.7 - Safety guards and devices
CAUTION!
Before using the equipment, make sure that it is correctly positioned and that it is
complete and in good working order.
Check that the equipment is complete and in good working order at the start of each
shift. If anything is lacking, report it to the maintenance supervisor.
CAUTION! There is no water level measuring device: always us the equipment with
the water level up to 4-5 centimetres from the top. If the equipment is used with the
water level in the tank too low, this would affect its operation and the quality of the
cooking process. If it is used with the tank empty, this would lead to overheating and
serious danger of burn injuries and damage to the equipment.
Shutdown device: if the readings of the temperature sensors differ, due to a fault in
either of them, the machine is shut down and an error message is displayed (ERR) or
(PROB).

CHAP. 5 - USE
5.1 - Using the machine
It is good practice to first load the bags containing the product to be cooked and only then
complete filling of the tank with water, so as to avoid exceeding the maximum allowed
level.
Fill the water to no more than the maximum level, and add some vinegar to prevent scale
and deposits building up, to the amount of 1/2 cup per 40 litres of water. Change the
water in the tank at least once a day to prevent deposits, algae etc. forming inside it.
The bags must be completely immersed in the water.
The bags should not occupy more than 30% of the tank's capacity, to ensure there is
sufficient water to deliver heat uniformly to the product.
Always use the cooking lid.
Check the water level regularly, since it can evaporate very quickly.
Once the cycle has completed, turn the machine off with the STOP button on the display.
