• During operation, with the door open, do not remove the fan cover; do not touch the moving fans and resistors which are still hot.
• The maximum working height, referred to the highest surface level, must be 160 centimetres from the floor. After installing the appliance apply the suitable adhesive symbol (supplied) at a height of 160 centimetres.
• To prevent boiling, do not use containers filled with liquids or food that liquefy with heat, in excessive amounts that cannot be easily kept under control. For this reason, only use trays that let you see inside the container. When extracting a tray containing hot liquid pay attention not to spill any liquid.

ELECTRIC SHOCK HAZARD

• Before performing any cleaning on the appliance, disconnect the power supply (from the safety circuit breaker) and water supply (close the water cock). Let it cool completely.
• Any modification to the electrical system that might be required to install the appliance must be carried out by competent personnel only.
• The power supply system must be fitted with an effective earthing connection according to the regulations in force.
• In the permanent connection to the mains, a protective pole switch must be installed between the appliance and the mains with minimum opening between the contacts of overvoltage category III (4000 V), sized for the load and complying with applicable regulations (automatic circuit breaker).
• If the power supply cable is damaged, it must be replaced by the manufacturer or their technical support service, or in any case by a person with similar qualifications, to prevent any risk.
• The appliance also has electrical components inside, for safety reasons it is forbidden to wash it with water or steam jets especially if aimed at the aeration vents on the metal surfaces of its outer casing.

FIRE HAZARD

• No foods containing easily flammable substances must be cooked, such as alcohol-based foods; self combustion phenomena might occur leading to fires and explosions in the cooking chamber.
• Before using the appliance, make sure that there are no non-compliant objects (e.g. User manuals, plastic bags or other flammable objects) or detergent residues, inside the cooking chamber.

INFORMATION FOR THE USER

• When the appliance is used for the first time it is recommended to run an empty cycle for 40/50 minutes at a temperature of 220/230°C. In this way all unpleasant yet fully normal smells due to heating the thermal insulation enveloping the cooking chamber and the silicone used for its external sealing are dissipated.
• Avoid prolonged permanence on the steel surfaces of foods containing acidic substances (lemon juice, vinegar, salt, etc.) which cause corrosive deterioration.
• The appliance must be cleaned regularly, even daily, to ensure the best functionality and to extend its service life.
• If specific detergents (degreasers) are used for cleaning stainless steel, ensure they do not contain corrosive acid substances (no presence of chlorine even if diluted) or abrasive substances. Carefully follow the instructions and warnings of the detergent’s manufacturer and take precautions such as using adequate rubber gloves.
• Strictly avoid using scouring pads, steel wool and scrapers that may ruin the treated surfaces.

COOKING TIPS

• In placing the food in the cooking chamber, maintain a space of at least 40 mm between trays in order not to excessively obstruct air circulation.
• Do not use trays with sides higher than necessary: the sides form barriers that prevent hot air circulation.
• Preheat the oven every time before cooking to achieve top performance.
• For cooking as consistently as possible, spread the food evenly in every tray taking into account its size, layer or thickness.
• Avoid adding salt to food in the cooking chamber.
• To check correct progress of the cooking cycle use the chamber’s internal lighting: avoid uselessly opening the door, which causes wastes of energy and longer cooking times.

RESIDUAL RISKS

INSTRUCTIONS FOR THE USER

2.1 Control panel

Programming cooking time – The oven is switched on by turning the programmer knob (Fig.1) to the symbol (continuous operation) or to the selected cooking time (up to 120 minutes); in the latter case the end of cooking is signalled by the oven switching off automatically.
Programming cooking temperature – Turn the thermostat knob (Fig.1) to adjust the temperature selected for cooking.
Programming humidity/steam quantity – To generate humidity/steam during the operation of the oven (hot cooking chamber), turn the knob of the automatic humidifier (Fig.1) to the desired value (from 1 to 5). By turning the knob to the • (off) position the humidifier stops working.

Important

• By turning the knob to positions from “1” to “4” the humidifier works by generating humidity/steam (water is fed into the cooking chamber) at automatically adjusted and cyclically repeated time intervals. (A higher number corresponds to a longer time of humidifier operation, therefore greater steam production).
• Turning the knob to position “5” disables the automatic control of the humidifier which works by continuously feeding water into the cooking chamber (continuous humidity/steam production).
• Before turning on the automatic humidifier, stabilize the temperature inside the cooking chamber to a value of at least 120°C in order to optimist the production of humidity/steam.

“End of cooking” programmer warning light – The green light of the programmer (Fig.1) indicates that the oven is working and that the cooking time is active.
Control thermostat warning light – The orange warning light of the control thermostat (Fig.1) turns off every time the programmed temperature is reached in the cooking chamber. It switches on again when the thermostat is triggered to re-establish this temperature.
Automatic humidifier warning light – The orange warning light of the automatic humidifier (Fig.1) indicates that the water solenoid valve is operating and therefore humidity/steam is being produced in the cooking chamber.
Internal oven light – With the oven in operation, the internal light is always on.
To turn off the oven – Place the “end of cooking” programmer and thermostat knobs in the off position. After use, close the water shut-off tap upstream of the appliance and disconnect it from the power supply.

2.2 Baking
For cooking, pre-heat the oven to the desired temperature before inserting the food. When the oven has reached the required temperature, introduce the food and check the cooking time. Turn off the oven 5 minutes before the theoretical time to recover the stored heat.

• Convection cooking (dry heat) – Switch the oven on and turn the thermostat knob to the desired temperature.
• Convection cooking + humidity/steam (dry heat + damp heat) – Switch the oven on. Turn the thermostat knob to the desired temperature and the automatic humidifier knob to the selected amount of humidity/steam.
• Defrosting – Switch the oven on and turn the thermostat and automatic humidifier knobs to off (•).

CLEANING

3.1 Manual cooking chamber cleaning
For hygienic reasons it is good practice to clean the cooking chamber on a daily basis, at the end of every day the oven is used. Correct cleaning also prevents the formation of corrosive phenomena inside the chamber, as well as preventing the danger of accidental combustion due to any grease and food residues accumulated over time.
To aid cleaning remove the side grilles. The cleaning detergents must not contain abrasive substances or substances of acid/corrosive nature. In case of lack of appropriate detergents it is sufficient to clean the cooking chamber with a sponge soaked in warm soapy water or warm water and a little vinegar. Rinse with plenty of water (use the suitable shower if available) and dry well with a soft cloth. The side grilles must be cleaned separately and fitted back on. When cleaning is completed leave the oven door slightly open.
3.2 Semi-automatic cooking chamber cleaning
Spray specific degreaser for stainless steel on the internal walls of the cooking chamber, on the side grilles, on the fan covers (do not spray onto the fans through the grille) and on the internal door glass.
Let the product act for about 20 minutes with the door closed.
switch the oven on adjusting the temperature at 100-120°C.
Run a cycle with 100% steam (automatic humidifier knob in position “5”) for about 15 minutes. Upon completing the cycle switch off the oven, let the cooking chamber cool and rinse it with plenty of water (use the suitable shower if available).
Dry by running a heating cycle adjusting the temperature at 180-200°C for about 10 minutes (repeat the cycle if necessary).
When cleaning is completed leave the oven door slightly open.
3.3 Cleaning the fans
The fans must be regularly cleaned with appropriate descaling products. All their parts must be thoroughly cleaned, eliminating any limescale. The fan cover must be removed to access fans. When cleaning is completed fit the cover back on operating in reverse order.
3.4 Cleaning the door gasket
For hygienic and functional reasons it is good practice to clean the door gasket at the end of every day the oven is used. It must be accurately washed with warm soapy water. It must be rinsed and dried with a soft cloth. Any scaling or food residues must be removed with special care, without using sharp metal tools that might irreparably damage the gasket.
3.5 Cleaning the door
The internal glass of the cooking chamber door may be cleaned using the same type of degreaser used for manually cleaning the cooking chamber; otherwise, a normal (non toxic) glass cleaning product may be used. A common glass detergent may be used also to clean the external door glass. In any case one may simply use warm soapy water. After rinsing dry the glass surface well with a soft cloth.
Should opaque spots form between the two glass panes, these may be removed as they are inspect able.
3.6 Cleaning the external casing
The outer steel surfaces must be cleaned with a cloth soaked in warm soapy water or mixed with a little vinegar, they must be rinsed well and dried with a soft cloth.
Should you wish to use specific products on the market, these must comply with the cleaning requirements set out in the “Information for the user” paragraph.
It is worth remembering that the counter supporting the appliance, or the floor surrounding the appliance area, should also be cleaned without using acid corrosive substances (e.g. muriatic acid) since the vapours released by them might corrode and deteriorate the outer steel shell and cause irreparable damage to the electrical components inside the appliance.
3.7 Inactivity period
Should the appliance not be used for a long extent of time, it is good practice to disconnect it from the power supply (act on the safety magnetic circuit breaker located upstream of the appliance) and water supply. It is recommended to clean it with care internally (cooking chamber) and externally, paying special attention to removing any salt residues which might lead to corrosion on the steel surfaces.
It is also recommended to protect the appliance with oil-based spray products (e.g. Vaseline oil) which form an effective protective film when sprayed on the surfaces.
Leave the door of the cooking chamber ajar.
Adequately covering the appliance, finally, allows it to be protected from dust.
