3.2 WARNINGS REGARDING THE FLUING SYSTEM
Before installation check, on the basis of the contents of the reference standard, to ensure that the volume aspirated by the fumes exhausting system is greater than the volume of combusted gas produced by the appliance (see point 1.1).
If the solution of combusted gas discharge under an extractor hood is chosen, observe the distance (shown in the fi gure) between the top of the discharge pipe and the lowest point of the hood fi lters. This distance is defi ned on the basis of discharge pipe diameter "D".
In the case of discharge direction to the outside or into a central fl ue (Fig. "1c"), the discharge ducts must NOT present an overall length in excess of 118"(3 meters), must NOT have any reductions in diameter, and must be subjected to periodic inspection and, when necessary, cleaning.
Warning: Since combusted gas (see fi gure) can reach very high temperatures, check the heat resistant properties of extension ducts if fi tted and the fi lters in the extractor hood to ensure the materials are compatible with the temperature conditions. In addition, periodically check the condition of the fi lters which, if excessively fouled with fat and dirt, will reduce the effi ciency of the suction system and may catch fi re.

ATTENTION:
- The periodic check of fi lter functionality, according to that indicated by the manufacturer, is important to avoid compromising appliance operation and to prevent the risk of corrosion.
- For good operation of the water softeners and fi lters make sure to regularly service them.
Note: The softener (Automatic Water Softener) with automatic regeneration has a kit (Resin Sterilizer) for sterilization of the resins (additional request).
- To prevent damaging the appliance, at every periodicregeneration do a fi lter wash cycle without introducing water in the oven.
- The manufacturer declines any liability in case of incorrect maintenance.
Attention:
Caution: the use of polyphosphates can cause adverse reactions regarding the waters PH and conductivity levels. It has also been linked to the creation of foam
that can also have adverse reactions on the water level circuit in a boiler. Therefore, the manufacturer does not recommend their use for scale control.
CHECK SUPPLY PRESSURE INPUT "CWI1" AND "CWI2"
The pressure measured upstream of the oven (and downstream of any WATER FILTRATION SYSTEMS installed). Must be greater
than 150kPa (1.5bar/22psi) and need not be greater than 450kPa (4.5bar/65psi) measured in in dynamic conditions, I.e. during a cleaning phase.
5.2 WATER DRAIN SYSTEM
The oven is supplied with an air-break system to prevent any backfl ow from the drainage system from reaching the oven’s internal circuits and the cooking chamber. The presence of this system means that the drain pipe can be connected directly to the mains drainage system or routed to a fl oor gulley with grating. The fl exible drainage hose or rigid pipe can be directed to the side or rear of the appliance if the oven is not positioned against a wall; this line must not be directed towards the front of the ap­pliance to prevent interference with roll-in grid racks. The drainage pipe internal diameter must be no smaller than the oven drain outlet (1 1/4"), no longer than 3 feet (1 metre) and must resist temperatures of up to at least 212°F (100°C). Avoid restrictions in the case of fl exible hose pipes, do not fi t elbows on metal pipes anywhere along the drainage line. Also avoid horizontal sections in which water might collect (minimum gradient 5%).

III. OPERATING INSTRUCTIONS
Before starting the appliance, carefully read this handbook. The instructions and information given in it are important for correct and optimum oven use.ANY POTENTIAL USER OF THE EQUIPMENT SHOULD BE TRAINED IN SAFE AND CORRECT OPERATING PROCEDURES.
• This appliance is intended for collective use only and is specifi cally designed to cook food. Any other use will be considered "improper use" and will void the warranty and manufacturer liability.
• To avoid obstructing the fume and steam discharge pipes, do not place pans or utensils of any kind on the oven.
• Do not place objects (e.g. pans) under the bottom of the oven, so as not to obstruct any cooling air inlet or outlet holes.
• Have the appliance fully checked periodically (at least once a year). For that purpose, it is advisable to stipulate a maintenance contract.
• The core probe is a precision component. Absolutely avoid impacts, forcing when inserting, and pulling of the fl exible cable (in particular when using the trolley-mounted structures). The
warranty does not cover the replacement of core probes damaged by improper use.
• Nel ciclo di cottura misto si consiglia di non superare la tempe­ratura di 392-410°F (200-210°C). Valori superiori possono ridurre l'effi cienza delle guarnizioni di tenuta cella.
• When arranging food inside the oven compartment, keep a space of at least 40mm between trays, to ensure better circulation of hot air.
• If the oven is installed near appliances that produce greasy fumes (e.g. fryer), make sure to use the air fi lter (not supplied), to be placed under the control panel, to protect the internal electronic components.
• During preheating of oven 20 GN 1/1 or 2/1, insert the trolley (without food) or the special accessory (not supplied) to close the bottom opening between the compartment and door. This prevents steam from coming out and into the control panel with consequent damage to the electronic board.
Do not salt food inside the oven, in particular with humid
cycles.
• Do not place fl ammable liquids (e.g. spirits) inside the oven during operation.
Attention!
The maximum height at which the trays are placed in the oven does not exceed 1.6 m. This applies if it is installed according to the instructions and with the use of original accessories. Whenever using supports different from ours, do not exceed the above-mentioned height when installing the oven. Otherwise there could be the risk of spilling hot cooking liquids (sauces, oil, melted fat, etc.) contained in the high trays and not visible during handling.

4.4.1 MULTIPHASE
Food can be cooked with different modes during its cycle and therefore in different phases. The oven enables programs consisting of several sequential pha­ses (up to a max. of 15 phases). During cooking, going from one phase to the next occurs automatically, until automatic stopping of the program with completion of the last set phase. A cycle with several phases is set by carrying out the following operations:
1) switch the oven on;
2) Set for PHASE 1:
- cooking mode (humidity if necessary);
- compartment temperature;
- cooking time (or alternatively the core probe temperature).
3) Press the "Phase" button and then the "Add new phase" button.
4) For PHASE 2 and following, set as per PHASE 1. When there are several phases, these will be listed, giving the relevant settings (an arrow will scroll the next ones which are not displayed).

4.4.4 ECODELTA
The ECO DELTA function enables cooking without har­ming the food with high temperatures; this ensures more gentle and more even cooking, with less weight loss. This is an advanced cooking method, where the oven compartment temperature varies according to the core temperature of the food.
The operator can select a Delta value of between 33.8°F e 248°F (1° e 120°C); it is advisable to set a value between 68°F e 158°F (20°C e 70°C), and a value between 50°F e 210°F (10°C e 99°C) for the Core Probe. The oven compartment temperature is automatically adjusted in order to always be higher than that in the core of the product.

The graph shows an example with a set Delta of 122°F (50°C) where the compartment temperature increases, keeping this dif­ference of 122°F (50°C) constant with respect to the core probe. This type of cooking is slower than the conventional cooking method but has the advantage of obtaining better product results and quality. This type of cooking is ideal for large pieces of meat.

4.4.6 FSC (Food Safe Control) The FOOD SAFE CONTROL (FSC) is a device enabling the
microbiological SAFE condition of the food to be controlled during cooking. Depending on the chosen food category (HIGH risk or STANDARD risk), during cooking the FSC recognises the moment when the food reaches an acceptable sanitisation level for its SAFE consumption. The cooking results can be shown on the DISPLAY. The process requires strict compliance with proper food processing practices according to the rules of hygiene, before and after cooking. Cooking using the FSC does not sanitise bad or deteriorated food, which remains so even after cooking.
To use the FSC, set a cooking cycle as described above. Always insert the CORE PROBE even with TIMED cooking cycles.
The FSC is composed of 2 categories:
FSC-STANDARD risk cooking: for foods having a low contamination level. (e.g. whole pieces of beef)
FSC-HIGH risk cooking: for foods having a high contamination level. (e.g. roulades of meat, mince­meat, poultry, pork, fi sh)
Set the HIGH or STANDARD risk category in the UTILITIES drawer and press "START" to start.
In this way, cooking with the FSC starts; if the safe condition is reached during cooking, a confi rmation will appear next to the FSC symbol:
F: 0.0
The Pasteurization factor F with value reached will also appear (if set).
If, on the other hand, cooking does not end in a safe condition, the FSC warns with a dialogue window and requests ending of the cycle automatically or manually by the user. At the end (in one way or the other), the following will appear:
FSC  for positive result FSC x for negative result
1) Remove the core probe "A" from its seat "B" and insert it in the product without forcing excessively, making sure the tip (the sensitive part) is positioned near the centre of the product.
A
B
MULTIPOINT 6-sensor core probe The oven is equipped with a MULTIPOINT core probe with 6 sensors along the entire stem, for correctly measuring the product core temperature even if the tip is not completely in the centre.
- Close the door and press the START button.
2) Stopping the cycle. When the required product core tempe- rature is reached the oven stops automatically and the elapsed cooking cycle time is displayed.
3) Core probe mode deactivation. Set a cooking time on the Timer whereas it is the opposite when the time is set.
The core probe mode is also deactivated when the oven is switched off.
Note:
With vacuum packed food products it is necessary to use the special external core probe (accessory available on request), to be connected to the USB socket. For its use, see the instructions included with the accessory.
. This action automatically cuts out the core probe,
4.4.7 CORE PROBE USE
(PRODUCT CORE TEMPERATURE CONTROL) The core probe allows accurate control of the core temperature of the product being cooked. This enables setting of the required value ( from 50°F to 210°F) (from 10°C to 99°C) and automatic stopping of cooking when that value is reached.
Attention: The core probe is a precision component. Absolutely avoid impacts, forcing when inserting, and pulling of the fl exible cable (in particular when using the trolley-mounted structures). The warranty does not cover the replacement of core probes damaged by improper use.
After selecting the time icon select that of the core probe and press START to start the cycle.
- Wait until the compartment temperature fi eld indicates reaching of preheating (the message LOAD appears).
- Open the door and introduce the product to be cooked.
Attention! Risk of burns. Always open the door with caution when the oven is hot.
5954 00J 02
4.4.8 END OF COOKING
At the end of the set time, the cooking cycle automatically stops and the oven buzzer sounds continuously. The display shows the message:
COOKING FINISHED !
Several parameters such as the following are also displayed:
- total time
- FSC a bar with relevant result will appear if set.
Open the door and remove the product.
Attention! Risk of burns. Always open the door with caution when the oven is hot.
Notes:
- The buzzer can be stopped in advance by carrying out any operation on the control panel or by opening the door. The cooking cycled can be manually stopped by keeping the STOP button pressed for a few seconds. A cycle identical to that just completed can be repeated by pressing the START button again.

4.3.9 SPECIAL CYCLES
The special cycles appear on the AUTOMATIC mode main screen, and are as follows:
- Low Temperature Cooking
- Proofi ng
- Reheating
LOW TEMPERATURE COOKING (EFS-LTC) Low temperature cooking is a specifi c cooking procedure par-
ticularly recommended for beef, such as entrecote, rump and llet, but also good for other types of meat, including veal, lamb, venison, turkey, duck, pork, etc. The meat cuts can be: roast-beef, shoulder, leg, saddle, steak with bone, rump, fi llet, cutlets, etc. The EFS-LTC is a completely automatic preset program, for obtaining tender and evenly cooked food.
Use the buttons under the list to view the relevant items for better management of Presets.
To upload, download or delete Presets it is necessary to open the drawer and press the required button:
The program comprises 4 main phases: PREHEAT, SEARING, MATURE, HOLD.
Select AUTOMATIC
Press the button
Set the program by entering the SEARING temperature, then enter the core probe fi nal temperature and press
START .
During the Preheating phase it is advisable to place the core probe outside the compartment.
After the PREHEAT phase (if necessary modify the compartment temperature already set) LOAD the food in the oven and insert the 6-sensor MULTIPOINT core probe (if necessary modify the core probe temperature already set). Close the door to start the cooking cycle. The SEARING (dry heat sealing of the food) phase starts, followed by quick oven cooling (CoolDown) for subsequent slow cooking with the MATURE phase (for tenderising the meat). This is followed by the food temperature HOLD phase. The entire EFS-LTC cycle can take several hours. One or more phases can be skipped, going to the next phase; this is useful, for example, when cooking is started (SEARING phase) with another appliance (e.g. frytop) and is to be completed with the oven (MATURE and HOLD phase). The MATURE phase cannot be skipped.
MULTITIMER By selecting MultiTimer mode it is possible to do an automatic
cooking cycle in several times with the selected cooking MODE Presets (e.g. Fish >Steamed). For operation and information regarding the MultiTimer, see the section of the same name 4.4 MANUAL > 4.4.2 MULTITIMER.
5954 00J 02
Main advantages:
- Excellent quality of the food.
- The standard LTC procedure guarantees repeatable results from year to year.
- Typical roast fl avour; succulence of the food from the centre to the edge.
- Uniform colour and perfectly even cooking.
- Quick maturing process, time-saving and possibility of using fresh cuts of meat.
