II. INSTRUCTIONS FOR INSTALLATION

Important: The oven outer panels must be removed to perform the operations described in this chapter. Since the appliance must be switched on to make certain adjustments, exercise the utmost care when working in the

vicinity of live electrical parts.

1. PLACE OF INSTALLATION

• The appliance must only be installed in adequately ventilated premises.

1.1 REFERENCE STANDARDS

• Install the appliance according to the prescriptions of current

safety standards.

2. POSITIONING

• Unpack the appliance and carefully remove the protective film from the outer panels to avoid leaving any trace of adhesive. Use a suitable solvent to remove any adhesive residues.

• Dispose of the packaging as instructed in the chapter on "Safeguarding the environment"

• Refer to the installation diagrams at the beginning of this booklet for the space requirements and connection dimensions of the appliance.

• Clearance of approximately 50 cm must be left between the appliance’s left side panel and adjacent structures in order to provide space for maintenance operations when needed; the right side panel and the rear panel of the appliance must be at least 10 cm from adjacent structures.

• Place the appliance in the required position and adjust the height of the work surface using the adjustable feet.

• The appliance is not suitable for built-in installation.

In the case of discharge direction to the outside or into a central flue (Fig. "1c"), the discharge ducts must NOT present an overall length in excess of 3 metres, must NOT have any reductions in diameter, and must be subjected to periodic inspection and, when necessary, cleaning.

Warning: Since combusted gas (see figure) can reach very high temperatures, check the heat resistant properties of extension ducts if fitted and the filters in the extractor hood to ensure the materials are compatible with the temperature conditions. In addition, periodically check the condition of the filters which, if excessively fouled with fat and dirt, will reduce the efficiency of the suction system and may catch fire.

3.3 INSTALLATION OF ACCESSORIES

Accessories can be easily installed by following the figures below together with the relative key. The screw holes for fixing accessories "A" and "F" are 3.5 mm in diameter and they must be drilled in-situ on the oven cover incorrespondence with the punch marks.

CONSTRUCTION TYPE

Important: Make sure steam from the oven’s drain or adjacent appliances does not enter the aeration vents under the appliance, designed to cool internal components

located at the bottom of the appliance.

3. COMBUSTED GAS DISCHARGE

3.1 FOREWORD

In relation to the combustion technology utilised, gas fired steam/ convection ovens are classified in accordance with their "Construction Type". For each of these types of appliances applicable regulations stipulate a specific type of combusted gas discharge system. Consequently, before installing the discharge system:

a) identify the "Construction type" of your model in Table 1

(technical data) or by checking the appliance identification dataplate;

b) choose the diagram with the type of construction among those shown below, depending on how you intend to exhaust the appliance fumes from the place of installation (e.g. discharge under extraction hood, direct to the outside, or in a central flue).

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 figure) between the top of the discharge pipe and the lowest point of the hood filters. This

5938 034 00

distance is defined on the basis of discharge pipe diameter "D".

specific characteristics given in this section.

HARDNESS FILTER

Water

in le t

^ OPERATING LEVEL (C = Convect, Convection).

The hardness values given in the table are for reducing scaling inside the steam generator and possible cooking compartment washing system. If the available water does not have these hardness characteristics a water softener must be installed. Therefore the Automatic Water Softener with automatic regeneration for installing on the inlet line, can be requested as an accessory; it has a Resin Sterilizer kit (also by request).

HARDNESS AND CHLORIDE FILTERS

The chloride concentration (Cl-) (ppm - mg/l) values with pH (>7) and Conductivity (µS/cm) (measured at 20°C) must be such as to not damage the steel structures inside the oven (only water inlet B). Therefore the characteristics of the available water must be identified in the graph given at the end of this handbook (page

299), if necessary installing at the inlet the type of filter indicated in the relevant area of the values.

The filters indicated are:

- No filter for chloride (Cl-) in the conforming area (Normal)

- Nanofilter

as an accessory on request, called Water Filter.

- Osmotizer. Make sure the water coming out the filter is inside the optimum

area (Normal). These filters also have the function of reducing the water hardness to optimum values (below 5°f), and therefore also act as a water softener.

ATTENTION: Periodical checking according to the filter manufacturer’s instructions is important to maintain its efficiency and avoid the risk of corrosion in the appliance. Level C ovens are convection ovens. If water having characteristics outside those specified is used to create humidity inside the oven, there will be the risk corrosion of the compartment and that present inside it. Carry out regular maintenance of the water softeners and filters to ensure their optimum efficiency. To avoid damage to the appliance, after every periodical regeneration do a filter cleaning cycle without introducing water in the oven. The manufacturer declines any liability in case of incorrect maintenance.

Important: The use of dosing systems designed to prevent the buildup of lime-scale in pipes (i.e. polyphosphate dosing systems) is prohibited since such systems may impair the performance of the appliance.

5.2 WATER DRAIN SYSTEM

- OVEN level A -

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 1 metre and must resist temperatures of up to at least 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%).

C - Oven drain C1 - Safety outlet

min 0,04m

Important:

- Do not obstruct the safety outlet C1.

- Do not connect the safety outlet C1 to the drainage system.

Note:

If water comes out of the AIR-BREAK (safety outlet C1) this means the drain C is blocked. Any elimination of the obstruction must

be carried out by specialised technical personnel.

- OVEN level B and C -

Connect drain fitting “C” to a drain pipe of the same diameter which is between 0.5 and 3 metres in length and is resistant to temperatures of at least 100°C. The drain pipe must be siphoned (height 80 mm) to an open drain “O” (“Air-Break”) or floor grating (see Fig. 12b) in order to prevent any back-flow from the sewage system from reaching the piping inside the oven or oven chamber. Check the hoses and elbows on metal pipes for kinks or pinching along the entire drain line and make sure the drain line has a minimum gradient of 5° to prevent water from collecting inside the system.

Important: The drain system must be installed so that any vapours from the open drain do not enter the aeration vents under the appliance.

For UK and COMMONWEALTH only:

In accordance with "the water supply (Water Fittings) Regulations 1999", it is mandatory that this appliance when installed to the mains water supply has fitted an approved "double check valve" connected upstream of the appliance. Failure to comply with these regulations may lead to the appliance being disconnected.

III. INSTRUCTIONS FOR USE

Before switching on the appliance, read this instruction booklet carefully because it contains important information concerning correct use of the appliance. If you require further information about the oven's features and cooking performance, consult your local dealer.

• Do not place pans or utensils on top of the oven to avoid obstructing the fumes and steam exhaust outlets.

• Do not insert objects (eg, trays) below the bottom of the oven so as not to obstruct the holes of entry or exit of cooling air.

• Periodically (at least once a year) the appliance should undergo a general inspection. For this purpose we recommend taking out a service contract.

• The core temperature probe is a precision instrument and must be handled with care. Avoid knocks, do not apply excessive force when inserting the probe, and do not pull on the lead (take care particularly when using roll-in racks). The guarantee does not

cover damage to the temperature probe caused by improper use.

• When using the mixed cooking cycle, do not exceed cooking temperatures of 200-210°C. Higher temperatures might impair the performance of the oven chamber seals.

• When placing food in the oven leave a gap of at least 40 mm between each pan to facilitate circulation of hot air.

• If the oven is installed near appliances that produce greasy fumes (e.g. fryer), make sure to use the air filter (not supplied), to be placed under the control panel, to protect the internal electronic components.

• During preheating of the oven 20 GN 1/1 or 2/1, insert the trolley (without food) 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.

MODELS with SAFETY SYSTEM (by request) The oven is equipped with a safety system to protect the user against scalding steam when the door is opened wide. Proceed as follows: a) Turn the oven door handle clockwise as far as it will go. The door opens slightly and is arrested by the door safety device. If there is a cooking program in progress it will be interrupted.

b) Turn the handle all the way counter-clockwise to open the oven door fully.

• Do not add salt to foods when inside the oven chamber, particularly during cooking cycles with humidification.

• Do not cook with flammable liquids such as alcoholic spirits.

Attention

If the oven has been installed according to our instructions and using original accessories cooking containers cannot be inserted at a height greater than 1.6 m. If supporting accessories other than the original ones are to be used, do not exceed the above specified height since this could result a spill hazard caused by hot cooking liquids (sauces, oil, melted fat, etc...) contained in the uppermost pans, which are

not visible during handling operations.

3. DESCRIPTION OF THE CONTROL PANEL

3.1 INTRODUCTION

To aid understanding of the operation of the oven, find the folding double page showing the control panel for your model among those included at the back of this handbook and then open it out and keep it open while reading this section. The following headings describe all the functions available on the various models in the range.

Some functions are shared by all models, others are available on specific models.

3.2 MAIN CONTROLS

Timer to control cooking time. Digital thermometer/thermostat: to control product core tem-

perature.

3.4 SPECIAL COOKING MODES

Main switch

Cooking cycle/program start/stop.

3.3 MAIN COOKING MODES

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

temperature of 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 250°C).

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 300°C). The regeneration program is composed of a single phase with the following characteristics:

- a special cycle with controlled humidity of 20 % (adjustable if required);

- a preset temperature value of 120°C (adjustable if required);

- use of full power;

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

started, remains active with door open or closed.

Important! Risk of burns.

Open the door with due care when the appliance is hot.

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

superheated steam(temperature from 101°C to 130°).

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.

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

Cook and hold cycle: for long slow cooking, typically for meat (large joints). It can be used in combination with convection, mixed, steam and regeneration modes. Fan operation is intermittent.

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: automatic or semiautomatic oven cleaning cycle (see section 7. CARE AND MAINTENANCE).

5938 034 00

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.

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)

Automatic sequence phases: to execute a 2-phase cooking cycle switching from one phase to the other automatically (LEVEL B e C ONLY).

3.5 ADDITIONAL FUNCTIONS

Set of controls for management of the programs library:

control keys to store, edit or delete cooking programs (LEVEL A only).

Program selector : to find and select the cooking programs stored in the memory (LEVEL A only).

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

probe with 1 sensor MULTIPOINT probe with 6 sensors

The LEVEL A oven is equipped with a MULTIPOINT probe with 6 sensors located at intervals along the wand, enabling the correct temperature to be read in the centre of the product even if the probe tip is not positioned at the product core. Close the oven door.

2) Select the desired cooking cycle and set the cooking temperature on thermostat TS. Important: do not set the cooking time on Timer TM.

3) Set the TEMPERATURE of the CORE PROBE by pressing the following illuminated button twice (button lights up):

Turn the knob clockwise (to increase the value) or counter clockwise (to decrease the value) to set the desired cooking TIME on the small DISPLAY. After 5 seconds the COOKING TIME display stops flashing to indicate that it has been SET.

Note:

In this case there is only one cooking cycle or phase so CURRENT remaining time and TOTAL remaining time will coincide.

4.3.4 SETTING AND USING THE PROBE (TO MONITOR PRODUCT CORE TEMPERATURE)

This temperature probe allows high precision control of the temperature reached at the core of the product being cooked so that the desired value can be set and the cooking cycle stopped automatically when the product core reaches the set temperature.

Important: The temperature probe is a precision instrument and must be handled with care. Avoid knocks, do not apply excessive force when inserting the probe, an do not pull on the lead (take care particularly when using roll-in racks). The guarantee does not cover damage to th core temperature probe caused by improper use.

- The green UTILITY LEDs will light up and one will be flashing.

E.g.: UTILITY selected

(flashing GREEN LED)

- Turn the knob clockwise or counter clockwise to select the utility required - the relative LED will flash (flashing GREEN colour).

- Press button U until the flashing LED relative to the UTILITY selected changes colour (flashing ORANGE colour).

- Wait a further 5 seconds for the LEDs relative to the selected utilities to illuminate steadily (steady ORANGE colour).

- Finally, start the cycle by pressing the START/STOP button.

A complete description of the different UTILITIES available is included in heading 3.4 SPECIAL COOKING MODES (page 42).

Note: If the UTILITIES are not used for 7 seconds they are automatically cut out, signalled by the relative button switching off.

- To cancel one of the following preset UTILITIES (ORANGE steady):

2) Set the desired cooking mode, oven chamber temperature, and cooking time (or, alternatively, core probe temperature) as described in this handbook.

3) Press the "1-2" /

"PHASE" button:

Phase 1 (I) LED

Phase 2 (II) LED

the phase 2 LED switches to RED (active phase) while the phase 1 LED is GREEN (inactive phase); at the same time the cooking modes button LEDs start flashing again to request a new setting for phase 2.

5) Select:

- phase 2 cooking mode;

- phase 2 oven chamber temperature;

- time (or core probe temperature) relative to phase 2;

6) The two-phase cooking cycle has now been set. Place the product to be cooked in the oven and press the START/STOP button to start the cooking cycle. The cooking cycle will start from phase 1 (phase 1 LED RED) and switch automatically to phase 2 (phase 2 LED RED) when the first phase terminates. When the oven switches from phase 1 to phase 2 the operator will be alerted by a brief audible signal. When phase 2 is terminated the cooking cycle will stop automatically as already described.

4.3.11 Delta Cooking

This is an advanced method of cooking, by which the oven chamber temperature varies in function of the core temperature of the food. The operator is able to select a delta value between 1°C < 120°C, we recommend using between 20°C < 70°C. The chamber

temperature will be adjusted to automatically remain above the rising core temperature exactly by the set value.

This type of cooking is ideally suited to large joints of meat. How to use it: Manual cooking mode.

1) Select the cooking mode, Ex.

2) Set a target core temperature value,

3) Go into advanced utility functions (Bottom row on Control

Panel) and select

Combi.

press the U button and turn the knob to select it so that it flashes (ORANGE flashing).

Press the U button again so that the UTILITY changes colour (GREEN flashing) and is thus cancelled.

- To cancel the other UTILITIES set another cooking cycle. In case of cycle already started, stop it, keeping the START/ STOP button pressed for 2 seconds before cancelling the UTILITY.

4.3.10 COOKING WITH TWO PHASES IN AUTOMATIC SEQUENCE

(LEVEL B and C ONLY) Level B ovens allow the execution of cooking cycles composed of two sequential phases. For example:

- Phase 1: - air-convection 200°C

- probe 70°C

- Phase 2: - mixed cycle 220°C

- 40 minutes The oven switches automatically from phase 1 to phase 2. To set a two-phase cycle proceed as follows:

1) Switch the oven;

5938 034 00

ECO - Delta.

At this point you will see on the oven temperature display

25 °C

which is a Delta value (you can change it by highlighting the temp area and turning the dial to reach the desired Delta – for example 50°C.) Close the oven door and press the start button to activate the cooking cycle. The core temperature of the meat may be for example 14 °C when the cooking cycle is started, the oven temperature will go to 75°C, (50°C above core temp), and then keep rising as the core temperature rises, maintaining a difference of 50°C(As the core temperature of the meat rises by one degree so too does the oven temperature). The two temperatures will displayed in the lower line on the display. If you selected a final core temperature of for ex. 67 °C, the final oven chamber temperature will be 117 °C at the end of the cooking cycle. This cooking method is much slower than the ‘normal ‘ way of cooking but the benefits are higher yields and better quality.

4.4 AUTOMATIC CONTROLS LEVEL A ONLY

Introduction: the automatic controls make it possible to perform

cooking cycles in special modes and also to store cycles after manual setting. For information on manual setting procedures refer first to heading 4.3 MANUAL CONTROLS.

Note:

If the oven is switched off after you have set up a cooking cycle manually the data you have entered will be lost since, in manual mode, the controller does not store the cooking cycle. To store manually set cooking programs for future use proceed as described in the following headings. The cooking cycles (or RECIPES) and programs (e.g. CLEAN) are managed by means of the following commands:

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 LEVEL A oven allows the execution of programs composed of several sequential phases. For example:

- Phase 1: - air-convection cycle 200°C

- core probe 70°C

- Phase 2: - mixed cycle 220°C

- time 40 minutes

- Phase 3: - air-convection cycle 250°C

- time 15 minutes and so on up to a maximum of 7 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.

4.4.6 USING PRESET PROGRAMS

Undeletable preset programs provide several standard service functions. The oven is supplied with the following preset programs:

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 oven 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 oven (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.

4.3.9 UTILITIES).

Major advantages:

• Excellent food quality.

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

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

5938 034 00

• 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 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 1:

Before cleaning the compartment with the CLEANING SYSTEM remove the grease filter (if present). 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:

In case of complete emptying of the detergent and/or rinse aid containers or emptying of their supply tubes, the

CLEANING

SYSTEM cycle must be started after firstly doing the CLEAN 1

cycle, then the same or other cycles. This operation allows the pipes to be refilled with the appropriate liquids and the cleaning cycles to be done correctly. If the CLEANING SYSTEM is not used for long periods, it is necessary to do a cleaning cycle (CLEAN 1) with water instead of detergent and rinse aid before and afterwards, to flush the respective supply pumps.

Note 2:

When setting a cooking cycle, press the P button twice and select the menu item FIND BY NUMBER OR FIND BY NAME, or press P, holding it down for a few seconds to exit setting and proceed as follows.

4.4.7 DELETING A RECIPE OR PROGRAM FROM THE MEMORY

1) Press button I to switch on the oven.

2) Press button P .

RECIPE NAME 01 COOKI NG POTATOES

selected option P : CO NF I RM

6) Press button P again and hold it down for a few seconds to exit the programs.

4.4.8 PASSWORD The PASSWORD function must be enabled by changing several parameters; for that purpose request the assistance of our After-Sales Service.

The PASSWORD allows the following functions to be locked in order to limit oven use (one or more by request):

- Disables the temporary modification of automatic programmes, including the special PreHeat, Low Temperature cycles and Recipes.

- Manual cooking cycles are made unusable.

- Prevents final modification, saving or cancellation of the automatic programmes. Once the PASSWORD is enabled, the oven is locked (after switching on) against the use of the above functions; a password must be entered to unlock it. To enter a password:

1) press button twice P and select the item PASSWORD, press P again, and the display shows:

_******* factory-set oven password

(8 characters formed of 8 empty spaces)

2) Press P (oven unlocked) and select CHANGE PASSWORD with the arrow button “v” (down).

3) Press P, the item New PASSWORD appears, enter the password (alphanumeric 8 characters or less) like entering the name of a recipe (see par. 4.4.4 STORING RECIPES or PROGRAMMES).

4) Press P, the item CONFIRM PASSWORD requests confirmation of the password entered by typing it again, then press P. After a short beep signalling successful operation, or a long beep if failed, the oven goes to the initial switching on status and is thus unlocked. To lock it again, just switch it off. To change a password repeat the previous operations from point 2). To quit the menu, if the PASSWORD is not known, switch the oven off and then on again.

9) - Open the oven door and rinse the interior of the chamber.

To facilitate the oven chamber cleaning procedure, remove the guides for roll-in racks located at the bottom of the cooking chamber and open the suction wall.

• To open the oven compartment suction wall A (Fig. 2) proceed

as follows:

- switch the oven off and disconnect the power to the appliance;

- undo (1a) screw B2 completely with a screwdriver,

- insert the tip of a screwdriver in slot B and prise (1b) inwards to

open the wall, unhooking it from the pegs B1 at the back.

To remove the suction wall completely follow these instructions:

- unscrew nut C1 with a hex wrench (2).

- lift (3) the suction wall to disengage it (4) from the lower pin C

of the oven chamber;

- lower (5) the wall to disengage upper pin D and then withdraw

the wall completely (6).

• When cleaning stainless steel, never use abrasive tools such as steel wool, wire brushes or scrapers, since they may leave ferrous particles which will promote rusting on the steel surfaces.

• If the appliance is not to be used for long periods, proceed as follows:

- Disconnect the electrical power supply and turn off the water and gas cocks; .

- Using a cloth soaked in vaseline oil, vigorously rub the stainless steel surfaces to apply a light protective film;

- Periodically air the place of storage.

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:

- pure vinegar (100%);

- a chemical descaler (as instructed below).

The oven must be switched on prior to descaling the boiler.

7.1.2 VINEGAR CLEANING METHOD

1) Close the water supply cock.

2) Empty the boiler by pressing the drain button

To refit the suction wall, repeat the steps in reverse order and retighten nut C1.

• If present, clean the oven compartment grease filter (not supplied) at least every three cooking cycles.

• If present, clean the air filter (not supplied) at least once a month, removing it from underthe control panel. Failure to clean the filter may affect its performance and impair cooking.

• Each day wash the stainless steel surfaces with lukewarm soapy water and then rinse and dry thoroughly.

3) Close the boiler drain after one minute by pressing the above button.

4) Remove the plastic cap from the boiler filler pipe and pour in 8 litres (6-10gn) or 16 litres (20gn) approx. of pure vinegar.

5) Open the water cock.

6) Run a “steam” cycle for 16 minutes.

7) Switch off the oven and wait 60 minutes.

8) Restart the oven in steam mode for a further 2 minutes.

9) Switch off the oven again and wait 60 minutes.

10) With the water cock open, re-open the drain outlet and drain off the vinegar (press the above button).

11) Switch off the oven.

12) Insert a rubber hose inside the boiler filler pipe and rinse thoroughly until the water flowing out of the drain is clear.

13) Refit the filler plug and close the boiler drain (press the above button).

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.
