This equipment is to be installed to comply with the applicable Federal, State, Local plumbing codes, or the Basic Plumbing Code of the Building Officials and Code Administrators International Inc. (BOCA) and Food Service Sanitation Manual of the Food and Drug Administration (FDA).

The appliance is fitted with two separate water inlets ("B" and "N"). The water lines supplying both inlets must be fitted with a mechanical filter and shut-off valve (keeping with local plumbing codes). Before fitting the filters allow the water to flow out for sufficient time to flush any solid particles from the piping.

4.1 WATER SUPPLY CONNECTIONS

4.1.1 WATER INLET "N".

Attention

The water supply pipe (not supplied) must have a 3/4" dia (20 mm) pipe and must be without elbow fittings.

The steam condensation system must be connected to a cold quality water supply in keeping with local plumbing codes, with

4.2 WATER DRAIN SYSTEM

The oven is supplied with an air-break system to prevent any backflow 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 floor gulley with grating. The flexible 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 flexible hose pipes, do not fit elbows on metal pipes anywhere along the drainage line. Also avoid horizontal sections in which water might collect (minimum gradient 5%).

WARING: BLOCKING THE DRAIN IS HAZARDOUS. Note:

If water flows out of the air-break system (near the oven drainage pipe) remove any obstructions clogging the drain. This water outlet pipe should be extended and directed to the

Main switch

Cooking cycle/program start/stop.

3.3 MAIN COOKING MODES

Air-convection cycle: To roast and gratin with a maximum

temperature of 572°F(300°C) (for 10 minutes max, 483°... 572°F)(251...300°C).

Mixed cycle: superheated steam. Uses the oven chamber heaters and steam generation system at the same time to keep food soft (maximum temperature 482°F)(250°C).

3.4 SPECIAL COOKING MODES

Utilities

Functions useful for the type of cooking to be executed.

Pause phase: set a time in this mode to delay the start of cooking programs or to set a pause interval between two cooking cycles (e.g. for dough proving).

Regeneration cycle: gives ideal humidity conditions for rapid heating of products to be regenerated (maximum temperature 482°F)(250°C). The regeneration program is composed of a single phase with the following characteristics:

- a special cycle with controlled humidity of 60 % (adjustable if required);

- preset temperature of 356°F (180°C)(can be altered if necessary);

- use of maximum power;

- a preset time of 30 minutes (adjustable if required) and once

started, remains active with door open or closed.

DANGER: CAVITY FAN AND STEAM WILL CONTINUE TO

OPERATE WHEN DOOR IS OPEN. WHEN IN REGENERATION CYCLE. OPEN DOOR SLOWLY TO AVOID THE RISK OF BURNS.

Steaming cycle: ideal for steam cooking (operating temperature automatically set at 212°F)(100°C). You can set low temperature steam for gentle cooking of foods in vacuum packs and for thawing (temperature from 77°F to 210°F)(25° to 99°C).

Displaying the humidity value: allows you to display the humidity level of the air-convection, mixed and regeneration cycles.

Digital thermometer/thermostat: to control the temperature in the oven chamber.

5958 931 01

Alternatively to the set cooking time it can also accept Cont cooking time or the core probe.

HOLD

Cook and hold cycle: for long slow cooking, typically for meat (

large piece of meat for roasting).

It can be used in combination with convection, mixed, steam and regeneration modes.

HACCP

HACCP: serves to record the cooking program in compliance with HACCP standards (Hazard Analysis and Critical Control Points). Depending on the system requested you can record

cooking data on a dedicated printer or directly on a PC.

Clean Cycle: semiautomatic oven cleaning cycle (see section 7. CARE AND MAINTENANCE).

USA

Low speed cycle (fan): for delicate cooking such as for baking cakes. Can be combined with any other cycle.

Reduced power cycle (heating): for delicate cooking such as for baking cakes. Can be combined with any other cycle.

3.5 ADDITIONAL FUNCTIONS

Set of controls for management of the programs library:

control keys to store, edit or delete cooking programs.

Cooking with ECO-DELTA: for cooking large pieces of food (5kg and above, e.g. whole turkey, leg of pork, etc.). In this cooking mode a temperature setting of between 1°C and 120°C is chosen. In this case, cooking is moderate and long, because the CHAMBER temperature is automatically adjusted according to that inside the food (CORE PROBE), maintaining a constant difference (ECO-DELTA) between them, from start to end of cooking. E.g:

COOKING: START ...... END

ECO-DELTA = 80°... 80...80... 80... 80°C (set) CORE PROBE = 10°... 11...12... 40... 60°C (set) CHAMBER = 90°... 91...92... 120... 140°C (result)

Air-convection cycle with oven chamber vent open: suitable for very dry cooking cycles; allows evacuation of humidity when necessary (maximum temperature 572°F)(300°C).

Door open indicator LED.

Limescale LED: when this LED starts flashing the boiler needs to

be descaled. Follow the instructions in section 7.

Program selector : to find and select the cooking programs stored in the memory.

Manual water injection into cooking chamber: serves to boost humidity levels during the cooking cycle.

Boiler manual water draining: press this button to drain the water from the boiler.

Important

! To prevent the build-up of lime-scale inside the boiler:  Make sure the water supply corresponds with the required

characteristics - see Installation.

 Always empty the boiler at the end of each day.

Rapid oven cooling: useful for passing from one type of cooking to another that requires a lower temperature; it allows the fan to run and automatic water (TS < 356°F)(180°C) injection even when oven door is open.

4.4.1 AUTOMATIC SEQUENTIAL MULTIPHASE COOKING

Food can be cooked using different temperatures during the cooking cycle (i.e. in several different stages). The oven allows the execution of programs composed of several sequential phases. For example:

- Phase 1: - air-convection cycle 392°F (200°C)

- core probe 158°F (70°C)

- Phase 2: - mixed cycle 428°F(220°C)

- time 40 minutes

- Phase 3: - air-convection cycle 482°F (250°C)

- time 15 minutes and so on up to a maximum of 6 phases. During the cooking cycle the oven advances from one phase to the next one automatically until the cooking program is completed and then stops automatically as soon as the last phase has been terminated.

To set a multiple phase cooking program proceed as follows:

1) Switch on the oven.

2) Set (see heading 4.3 MANUAL CONTROLS):

- cooking mode for phase 1;

- oven chamber temperature for phase 1;

- cooking time (or core probe temperature) for phase 1.

3) Press button P and the DISPLAY will show the flashing value 1 (phase 1) and the description P:MENU.

4) Press button P to open the menu, the option P:ADD PHASE appears on the DISPLAY (it is also possible to select another option from the menu).

phase 1 flashing 1 selected item P : A DD PH A SE

5) Press button P to confirm this option; the DISPLAY will now show a flashing number 2 (phase 2) and some of the MANUAL CONTROL functions will start flashing.

phase 2 flashing 1 2 selected item P : ME NU

6) Set new values, as described in point 2), but this time with reference to phase 2.

7) To set additional phases repeat steps 4, 5 and 6 up to a maximum of 7 phases.

8) The multiple phase cooking program has now been set up. Place the product to be cooked in the oven and press the Start cycle button.

The cooking cycle will start from phase 1 (value 1 flashes in alternation with a dot on the relative DISPLAY) and, when phase 1 is terminated, it will advance automatically to phase 2 (value 2 flashes in alternation with a dot on the relative DISPLAY) and so on until all set phases are completed.

phase 2 in progess 1 2

The transition from one phase to the next is signalled by a short audible signal. When the last phase is terminated the cooking cycle will stop automatically as already described, and the appliance will emit a double intermittent audible signal. To repeat the same multiple phase cycle simply press the START/ STOP button again.

While the cooking cycle is in progress you can skip one or more of the phases as follows:

- press the (>) button one or more times to select the successive phases.

- press button P once and then press it again at the "SKIP PHASE" option to confirm the selected phase and cause it to start.

LOW TEMPERATURE COOKING (EFS-LTC) Cooking at low temperature is a specific cooking procedure especially for beef, e.g. prime rib, beef fillet, top round, tenderloin, but also for other meat items like veal, lamb, venison, turkey, duck, pork, etc The meat cuts can be: strip loin, shoulder, leg, saddle, T-bone steak, rump, fillet, chops, etc. The EFS-LTC is a preset, fully automatic program to obtain matured, tender and uniform cooked food.

The program comprises 4 main phases:

PREHEAT, SEARING, MATURE, HOLD. Set the program as indicated below for the pre-sorted programs. When the word LOAD appears on the large display, after the PREHEAT phase (If necessary change the already set cooking chamber temperature) PLACE the food in the air-o-steam and insert the 6 Point Multi Sensor, core probe. (If necessary change the already set probe temperature). Close the door and start the cycle by pressing the START button again. The SEARING (sealing of the food by dry heat) phase starts, followed by the suddenly Cool Down for subsequent slow cooking; in the MATURE phase (responsible for tenderising the meat) the relevant duration flashes on the large display of the core probe (press any button and the duration disappears). This is followed by the final HOLD phase to keep the food on a certain temperature. The entire LTC cycle (including the HOLD phase) can last for a max. of 24 hours.

One or more phases can be skipped, going to the next phase (see SKIP PHASE in par. 4.4.1 AUTOMATIC SEQUENTIAL MULTIPHASE COOKING); this is useful, for example, when cooking is started (SEARING phase) with another appliance (e.g. fry top) and is to be completed in the air-o-steam (MATURE and HOLD phases). The MATURE phase cannot be skipped; this means that if only the HOLD phase is to be used just set the relevant UTILITY (see par. 4.3.10 UTILITIES).

USA

Major advantages:

• Excellent food quality.

• Standardized procedure LTC guarantees repeatable results year-in - year-out.

• Typical roast aroma, juiciness from centre to the rim.

• Uniform colour and perfected evenness in the degree of doneness.

• Fast maturing process - time saving and use of fresh cut.

• Significant less cooking shrinkage, 5-8 % (depend on food quality and selected core temperature).

• Remarkable gain of portions for selling.

• Dramatic energy-saving due to the intelligent EFS - LTC program.

CLEANING SYSTEM (AIR-O-CLEAN) This system executes an automatic oven chamber cleaning procedure using suitable detergents according to the level of soil detected; the program has four different cleaning cycles.

CLEAN 1 Soft (light) For fresh soil deriving from low fat cooking (e.g. after a STEAM cooking cycle)

CLEAN 2 Medium (normal) If the oven chamber is only moderately soiled and after cooking fatty foods.

CLEAN 3 Strong (intensive) If the oven chamber is very dirty due to cooking of high fat foods (e.g. roasted chicken, sausages).

CLEAN 4 X-Strong (super intensive) For heavy grime resulting from very high fat foods (e.g. roasted chicken, sausages) also with dry residues (baked-on food).

F00...---> F19... (recipes) These are the 20 pre-stored recipes of the main international dishes. For further information see the relative recipe book.

Proceed as follows to use preset programs:

Note:

The CLEANING SYSTEM cycle will commence when the temperature automatically reaches 70°C in the oven chamber. Before carrying out a CLEANING SYSTEM cycle make sure the containers (located under the control panel) are supplied with cleaning products of the required type: refer first to section 7. CARE AND MAINTENANCE.

Warning:

If the detergent and/or rinse aid containers are empty or the relative supply lines are empty, before starting the CLEANING SYSTEM cycle a preparatory cycle must be executed. This allows the supply pipes to fill with the required liquids and ensures the subsequent cleaning cycle is performed correctly.

7.1 PERIODICAL MAINTENANCE OF THE BOILER

• The build-up of lime-scale inside the boiler is signalled by

illumination of the LED shown below.

When this LED illuminates the boiler must be descaled.

The manufacturer declines all liability for failure to clean the boiler when necessary. Moreover, the repair or replacement of scale-damaged parts is not covered by the guarantee if the characteristics of the water supply do not comply with those stipulated (see corresponding paragraph).

The boiler may be descaled using either:

7.1.3 DESCALER CLEANING METHOD

If you decide to descale the boiler using a chemical product, follow the directions provided by the product supplier. For example, when using ECOLAB's “STRIP-A-WAY” descaler, proceed as follows:

• Follow the instructions given in the previous paragraph and supply the following product quantities via the boiler filler pipe:

- 2 litres of descaler liquid plus 6 litres of water (6-10gn).

- 4.5 litres of descaler liquid plus 11.5 litres of water (20gn).

• Run a “steam” cycle for 12 minutes.

• Switch off the oven and wait 40 minutes.

• Reopen the boiler drain outlet and proceed as described in the paragraph above.

IMPORTANT Insert a rubber hose inside the boiler filler pipe and rinse thoroughly with water to remove all traces of descaling agent.
