4.2. Use • The appliance has been designed and perfected under laboratory testing conditions to offer exceptional levels of performance. However, to minimise energy consumption (electricity, gas and water) , we recommend turning the appliance off when not in use for long periods and not using it, for example, with the door open as this may impair the oven's performance. We also recommend preheating the appliance immediately prior to use.
Important: Installation and maintenance of the appliance
and its conversion to a different gas supply, must only be performed by a qualified installer authorised by the manufacturer. • This appliance is intended for industrial use only and is specifically designed to cook food. Any other use of the appliance is deemed improper. The appliance must only be used by trained staff and must be supervised at all times when in use. • Switch off the appliance if it breaks down or malfunctions. • Only contact the technical service centre authorised by the manufacturer for repairs and only use original spare parts. Failure to comply with the above requirement may jeopardise the safety of the appliance and render the guarantee null and void. • When the oven is hot, open the oven door with care to avoid burning your hands. • Do not sprinkle salt on food already in the oven, particularly when using one of the steam cooking cycles (see "Instructions for use"). When batch cooking foods with a high salt content (i.e. seafood), thoroughly wash the oven chamber at the end of the day. • Do not wash the appliance with water jets.
4.3. Cleaning • To minimise the emission of pollutants into the environment, we recommend cleaning the appliance (externally and, where necessary, internally) with products which are at least 90% biodegradable.
4.4 Disposal • The appliance must be disposed of properly at the end of its service life. • The appliance is made from 90% recyclable materials (stainless steel, iron, aluminium, galvanised sheet steel, etc.). These materials may therefore be scrapped in accordance with local waste disposal regulations at a conventional recycling plant. • Make the appliance unusable by cutting off the power cord. Also remove any compartment or interior closure device fitted on the appliance to prevent persons from becoming trapped inside.
• Do not use products containing chlorine (bleach, hydrochloric acid etc.) even diluted, to clean steel surfaces. • Do not use corrosive substances (i.e. muriatic acid) to clean the floor under the appliance. • For more information, refer to the chapter on "Care and maintenance".

II. INSTRUCTIONS FOR INSTALLATION Important: The external oven 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 the appliance’s “live” parts.
1.
INSTALLATION PLACE
• The appliance must only be installed in adequately ventilated premises.
1.1. APPLICABLE STANDARDS Install the appliance in compliance with the safety standards currently in force in the country of use.
2.
POSITIONING
• Unpack the appliance and carefully remove the protective film from the external panels to avoid leaving any trace of glue. Use a suitable diluent to remove any glue residue. • 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. • The LH side of the appliance must be installed at least 50 cm from adjacent units to provide easy access for maintenance, while the RH side must be installed 10 cm from adjacent units made from flammable materials. • 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.
Important: Make sure vapours from the oven’s drain or adjacent appliances do not enter the aeration vents under the appliance, which cool the oven’s internal components.
3.
GAS EXHAUST
3.1. INTRODUCTION Gas-heated Convection-Steam ovens are classified according to their "Construction type" on the basis of the exhaust technology used. Each type of appliance must therefore be fitted with the specific gas exhaust system stipulated by applicable standards. Before installing the exhaust system, you must therefore: a) identify the "Construction type" of your oven model by referring to Table 1 (Technical Data) or the appliance identification label; b) select the appliance construction diagram from those illustrated below featuring the required gas exhaust system (e.g. : exhaust pipe under extractor hood, externally-ducted or centralised flue exhaust system).

3.2. ACCESSORY INSTALLATION The accessories may be easily mounted using the key and figures below as a reference. The diameter of the fixing screw holes for accessories "A" and "F" is ø 3.5 mm. These holes must be drilled on site where marked on top of the oven.
3.3. GAS EXHAUST SYSTEM WARNINGS Before installing the system, make sure the extraction capacity of the fumes exhaust system is greater than the exhaust gas generated by the appliance, as specified by applicable standards (see point 1.1). In the case of exhaust pipes installed under an extractor hood, make sure the end of the exhaust pipe is positioned distance "2D" from the bottom edge of the filters on the extractor hood as shown in the figure below. This distance is defined by diameter "D" of the exhaust pipe. In the case of externally-ducted or centralised flue exhaust systems (Fig. "9"), the exhaust ducting must NOT exceed 3 metres in length or vary in diameter and must be routinely checked and cleaned. Important: Make sure any extension ducting and the filters inside the extractor hood are made from non-flammable materials since the exhaust gasses generated can reach extremely high temperatures (as shown in the figure). Periodically check the condition of the filters and, if dirty, clean. Filters which are very greasy may impair the performance of the extractor system and even cause fires.

WATER MAINS CONNECTION
(Refer to the installation diagrams at the beginning of this booklet). • The appliance must be connected to the mains power supply in compliance with current regulations. • Before connecting the appliance to the mains supply, make sure that the voltage and frequency shown on the appliance rating plate correspond with that of the power supply. • The appliance must be connected following the instructions shown in the enclosed electrical diagram with the phase wires (L) and neutral (N) connected as indicated on the plate next to the connection terminal board. • The appliance must be permanently connected to the mains power supply with an H05 RN-F type cable. The power supply cable must be protected by a metal or rigid plastic tube. If the appliance is connected by way of an existing lead, do not insert the installation tube in the appliance and make sure the tube has no sharp edges. • A safety cutout switch of suitable capacity with a contact breaking distance of at least 3 mm and a delayed-action T fuse rated at 16 A must be fitted upstream of the appliance. This cutout switch must be installed near the appliance in the permanent electrical system of the premises. • The appliance must be suitably earthed. The earthing conductor must therefore be connected to the terminal marked G on the connection terminal board. The appliance must also be connected to an equipotential system. This connection is made using the stop screw marked E located on the outside of the appliance near the power cable inlet. The equipotential wire must have a minimum cross-section of 10 mm2.
4.1 INSTALLING THE POWER SUPPLY CABLE (Fig. "10") To access the power supply cable connection terminal board, proceed as follows: • Undo screws "V" fixing the terminal board support panel located underneath the appliance on the front LH side. • Feed the power supply cable through cable clamp inlet "B". • Connect the cable to terminal board “A” as shown in the enclosed wiring diagram and fasten with the corresponding cable clamp. • Remount the panel and secure with the fixing screws. The manufacturer declines any responsibility for failure to comply with existing accident prevention standards.
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 cock. Before fitting the filters, pump water through the system to expel any solid particles from the piping.
5.1. WATER SUPPLY CHARACTERISTICS 5.1.1 Water inlet "N". The steam condensation system must be connected to a cold drinking water supply with the following characteristics: total hardness: up to 40°F; pressure: 150 to 250 kPa (1.5-2.5 bar); higher pressure values result in increased water consumption. 5.1.2 Water inlet "B". The steam production system must be connected to a drinking water supply with the following characteristics: total hardness: 0.5 to 5 °F to prevent the build-up of limescale inside the boiler (or oven chamber on models with automatic generation). On request the oven is supplied with an optional water softener equipped with automatic regeneration system which must be installed on inlet line "B". This device is also supplied with a resin sterilisation kit (available on request). pressure: 150 to 250 kPa (1.5-2.5 bar); higher pressure values result in increased water consumption. chlorine ion concentration (Cl -): not more than ~10 ppm (acceptable value) to avoid damaging the oven's internal steel elements. pH: over 7. On request the oven is supplied with a special filtration unit which is installed on inlet line "B". This unit also acts as a water softener by reducing water hardness to less than 5°F. electrical conductivity: 50 to 2000 µS/cm (20°C). Important: Only install the water treatment systems supplied by the manufacturer. Failure to do so automatically invalidates the guarantee. The use of dosing systems designed to prevent the buildup of lime-scale in pipes (i.e. polyphosphate dosing systems) is also prohibited since it may impair the performance of the appliance.

5.3 WATER DRAIN SYSTEM (Fig. "12a-12b") 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.

III. INSTRUCTIONS FOR USE Before switching on the appliance, carefully read this instructions booklet, in as much as it contains important information concerning correct and optimum 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 fume and steam exhaust ducts. • Once every six months the burners, the uniformity of their flame and related components must be inspected by a qualified technician. • Periodically (at least once a year) the appliance should undergo a general inspection. For this purpose we recommend taking out a service contract. Some models are equipped with a temperature probe which measures the core temperature of products. This is a precision instrument and must therefore be handled with the utmost care to avoid knocks or damage caused by abrupt insertion or removal of the lead (particularly when using trolley-mounted units). The guarantee does not cover damage to the temperature probe caused by improper usage. • When using the mixed cooking cycle, do not exceed cooking temperatures of 200-210°C which might otherwise impair the performance of the oven chamber seals. • When using the oven, leave a gap of at least 40 mm between each container to facilitate the correct circulation of hot air inside the oven.
Important! Risk of burning. Open the door with due care when the appliance is hot.

When the set cooking time has elapsed the cooking cycle stops automatically and the oven beeps for about one minute to let you know that the cooking cycle has finished. Open the oven door and remove the cooked food. Important! Risk of burning. Open the door with due care when the appliance is hot.
Note: - To silence the acoustic signal before the full minute has elapsed, simply press any button on the control panel or open the oven door. - The cooking cycle may also be interrupted manually by holding the cycle Start/Stop button pressed in for two seconds.
To preheat the oven prior to cooking, proceed as follows: Switch on the empty oven: - set the required cooking cycle; - set the preheating temperature on thermostat TS; - set timer TM to "Cont"; - wait until the preheating temperature is indicated on the oven temperature display, open the oven door and place the food inside. Important! Risk of burning. Open the door with due care when the appliance is hot.
Close the oven door, set the required cooking time on timer TM and, if necessary, readjust the cooking temperature on thermostat TS.
5.11. COOKING WITH TEMPERATURE PROBE (Core temperature probe) This cooking method offers precise control over the core temperature of products. Simply set the required core temperature and the cycle will stop as soon as this temperature is reached.
Important: The temperature probe is a precision instrument. It must therefore be handled with the utmost care to avoid knocks or damage caused by abrupt insertion or removal of the lead (particularly when using trolley-mounted units). The guarantee does not cover damage to the core temperature probe caused by improper usage.
1) Switch on the oven and, if necessary, preheat. 2) Stop the cooking cycle. Remove the temperature probe from its holder and insert in the product, taking care not to force it. Make sure the sensor head is positioned at the heart of the product and close the oven door. 3) Select the required cooking cycle and set the cooking temperature on thermostat TS. Important: do not set timer TM. - The temperature setting immediately starts flashing on display PRB. The preset start setting is 50°C. 4) Press the up and down buttons on probe control PRB to increase or reduce the temperature setting shown on the display.

6) End of cooking cycle with temperature probe. When the target core temperature is reached, the oven switches off automatically as described in paragraph 5.8 above. 7) Deactivation of temperature probe. (Only possible when the cooking cycle has stopped). Set any cooking time on timer TM to automatically zero any previous temperature probe setting. Likewise, set any temperature setting on probe control knob PRB to automatically zero any previous timer setting. The temperature probe cooking cycle may also be deactivated by switching off the oven.
5) Select: - the required cooking cycle for phase 2; - the required cooking temperature for phase 2; - the required time setting (or probe temperature setting) for phase 2. 6) To set additional phases, simply repeat the steps outlined in points 4 and 5 above to program up to 6 phases. 7) The multi-phase cooking cycle is now set. Place the product in the oven and press the Cooking start button.
5.12. AUTOMATIC MULTI-PHASE COOKING CYCLE
startnol_elux.eps
Functional level 6 ovens enable you to program cooking cycles comprising up to 6 sequential phases. For example: - Phase 1: - Convection, 200°C - Temperature probe, 70°C - Phase 2: - Mixed, 220°C - Length, 40 minutes - Phase 3: - Convection, 250°C - Length, 15 minutes and so forth up to a maximum of 6 phases. The cycle automatically passes from one phase to the next until the program stops on completion of the last phase. The multi-phase cooking program is controlled by the button illustrated below.
The cooking cycle starts at phase 1 (phase led 1 red) and then automatically proceeds to phase 2 (phase led 2 red), and so forth until completion of all the programmed phases. The start of a new phase is also signalled by a brief acoustic signal. On completion of the last phase, the cooking cycle stops automatically as previously described.
5.13. EDITING/DISPLAYING COOKING SETTINGS - Before starting the cooking cycle, you can modify the following cooking parameters: 1) cooking cycle; 2) cooking temperature TS; 3) cooking time TM; 4) probe temperature PRB (instead of cooking time). - Once the cooking cycle has started, you can only modify the cooking parameters by pressing the Parameters view button.
1 2 3 4 5 6 fase_elux.eps
This button is equipped with six indicator leds (one for each phase) which illuminate red or green depending on whether the relative phase is activated or deactivated. Those leds which remain extinguished instead indicate phases which have not yet been selected. To program a multi-phase cooking cycle, proceed as follows:
occhio_elux.eps
In this mode, you can view and change the settings for the active phase (as indicated by the corresponding red phase led). To view or edit the parameters of other phases (if set), you must instead press first the view button and then the phase button.

Etub - Steam boiler temperature thermostat tripped (150°C). Etuc - Oven chamber temperature thermostat tripped (320°C). EFLP - Motorised oven steam vent valve faulty. (Functional level T6 only)
IMPORTANT! If an error code is displayed during a cooking cycle, the oven emits a continuous acoustic warning signal and the cooking cycle is interrupted. Thereafter, the oven may only be used if the cooking cycle selected does not use the damaged component which caused the alarm to trip in the first place. Notify your Technical Service Centre of the alarm code displayed.
6.2.
TURNING OFF IN THE EVENT OF A FAULT
If the appliance malfunctions, switch off the appliance as follows: • Disconnect the mains cutout switch upstream of the appliance and close the water and gas cocks. • Contact a technical service centre with personnel trained and authorised by the manufacturer.
6.3.
CARE AND MAINTENANCE
• At the end of each day clean the oven interior with an oven cleaner, following the product supplier's directions. • Do not wash the appliance with water jets. • Do not use products containing chlorine (bleach, hydrochloric acid etc.) even diluted, to clean steel surfaces. • Do not use corrosive substances (i.e. muriatic acid) to clean the floor under the appliance.
clean_ac_elux.eps
After about 5 minutes, the oven starts to beep. 2) - Open the oven door and spray the oven surfaces with a suitable oven cleaner. 3) - Close the oven door again and wait until the automatic twominute countdown has elapsed on the oven temperature display. When the display returns to zero, the oven automatically starts a ten-minute steam cycle (phase 2), after which the oven beeps again and the "CLEAN" button led switches off. The cleaning cycle is now over. 4) - Open the door and thoroughly rinse inside the oven. For best cleaning results, remove the trolley-mounted unit runners (if fitted) in the oven base and also the lateral air diffusors supporting the oven trays and the fan panel. • To remove the air diffusors from inside the oven, proceed as follows: - Lift the diffusor and rotate to release the two front pins. This done, remove the diffusor by detaching the hooks from the slots in the fan panel. To remount the diffusor, simply repeat the above procedure in reverse order. • To remove fan panel "A" (Fig. "18") from inside the oven, proceed as follows: - Switch off the oven and disconnect from the power supply. - Remove the lateral air diffusors and, using a hex wrench, tighten nuts "D" on the upper threaded bolts until they are flush with the oven ceiling. - Lift the panel and detach from the two lower bolts. - Finally, push the panel down and detach from the two upper threaded bolts.

or operating the manual water drain lever under the control panel on all other models. 3) Close the boiler drain after one minute using the relative button or lever. 4) Remove the plastic plug from the boiler inlet tube and pour in 9 litres of pure vinegar. 5) Open the water cock. 6) Run a “steam” cycle for 20 minutes. 7) Switch off the oven and wait 60 minutes. 8) Restart the oven for a further 10 minutes. 9) Switch off the oven again and wait 60 minutes. 10) With the water cock still open, use the corresponding button or lever to open the boiler drain outlet and drain off the vinegar. 11) Switch off the oven. 12) Insert a rubber hose inside the boiler inlet tube and rinse thoroughly until the water flowing out of the drain is clear. 13) Refit the plug in the tube and close the boiler drain (again using the relative button or lever).
19 • Each day wash the stainless steel surfaces with lukewarm soapy water, rinse and dry thoroughly. • When cleaning stainless steel, never under any circumstances use abrasive materials such as steel wool, iron brushes or scrapers, since they may leave ferrous particles on the steel surface, thereby causing it to rust. • If the appliance is not used for long periods, proceed as follows: - Disconnect the electrical power supply and close the water and gas cocks; - Using a cloth soaked in vaseline oil, vigorously rub the stainless steel surfaces until they are well greased; - Periodically air the premises.
6.4.2 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: • Following the instructions described above, fill the boiler with 2.5 litres of descaling liquid and 6.5 litres of water using the boiler inlet tube. • 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.
6.4.
PERIODICAL STEAM BOILER MAINTENANCE (IF FITTED) • The build-up of lime-scale inside the boiler is signalled by illumination of the led shown below.
IMPORTANT Insert a rubber hose inside the boiler inlet tube and rinse thoroughly with water to remove all trace of descaling agent. • Refit the plug in the tube and close the boiler drain (using the relative button or lever). After descaling the boiler, it is a good idea to run a 30-minute steam cycle (C3) with the oven empty.
calcare_elux.eps
When this led illuminates the boiler must be descaled. The manufacturer declines all liability for failure to clean the boiler when specified. 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%); or - a chemical descaler (as instructed below).

Changing the oven bulb (Fig. "20") If the oven bulb burns out, replace as follows: • Disconnect the appliance from the power supply. • Unscrew the four screws fixing ring nut "A" to the light fixture and remove glass shield "V" together with seal "G". • Wrap a clean piece of paper/cloth around halogen bulb "L" to prevent burning your fingers when removing it and replace with one with the same characteristics (12V - 20W - 300°C). • Make sure the safety glass is correctly fitted inside the seal and remount in the fixture. This done, fix the ring nut using the four screws, after first lubricating the seal with non-toxic silicon grease.
Condensation collection tray (Fig. "22") If condensation collection tray “R” fills with water, check the condition of rubber hose "T" or the fitting connecting it to the drain pipe. To do this, detach hose "T" from the hose connector and clean thoroughly. Condensation collection tray “R” may be extracted from the front of the appliance simply by detaching drain hose "T" and undoing stop screw "F" underneath the oven.
22 20 Replacing the oven door seal (Fig. "21") N.B.: The oven door seal is prone to normal wear and should be replaced whenever it starts to harden or crack. To change the oven door seal proceed as follows: • Prise the seal off its seat and remove any trace of old silicon. • Apply silicon sealant to points "1" and "2" along the seal support frame. • Fit the new seal by first pushing inside edge "1" over the corresponding seat edge, taking care to press it round the corners first. • Then, using a hook, stretch outside edge "2" of the seal over the other seat edge.
Cleaning and checking the drain system Periodically clean the drain pipe and check for obstructions which may prevent the water from draining. Cleaning the inner glass panes of the oven door (Fig. "23") Only clean the inner glass panes when the glass is cold and never use abrasive cloths or detergents. To access the internal door cavity, open the internal glass pane hinged to the door. • To do this, open the oven door and rotate upper and lower stops "F" through 180°. For this purpose, insert the rounded end of a table knife in the stop slots. This done, open the internal glass pane. A special latch is mounted on the bottom hinge to limit the opening radius of the internal glass pane.
23 After cleaning, close the internal glass pane so that it is flush against the rubber buffers and rotate the stops back through 180°.
