1.3 TRANSPORT OF THE OVEN AND PACKAGING REMOVAL
Upon receipt of the oven and before installing it, check the packaging is intact and there are not visible damages.
Also check that along with the oven you receive also the documentation, consisting of:

• Instructions for installation, use and maintenance
• Chart to check correct installation
• Wiring diagram
• Label ISO 3864-1

Before bringing the oven to the point, where it must be installed, check the following:
The doors are large enough to allow passage of the oven The floor supports the weight.
According to the model of oven, its dimensions and its weight, use suitable facilities to handle goods during transport and installation, able to guarantee stability in order to avoid overturning, falls or uncontrolled movements of the appliance or its components. Keep the oven packed until you reach the site where the oven is going to be installed.
The packaging makes the handling of goods easier and protects the oven from accidental push.
During moving and installation of the oven, the installer must comply with accident-prevention regulations in force at the place of installation (use of safety shoes, gloves, etc.) Remove the packaging taking care not to damage the oven. The adhesive film, that protects the surfaces made of stainless steel can be removed also after you have positioned the oven on the corresponding stand or the support surface.
ATTENTION: Packaging materials and adhesive film are potentially dangerous. For this reason, they must be kept out of the reach of children and properly disposed of in com- pliance with local directives.
You should separate packaging materials (wood, cardboard, plastic…) and dispose of them separately, in compliance with directives in force at installation site.
Note: Take the protective film off the stainless steel parts by hand before starting the appliance.
Do not use abrasive substances and/or metal objects. Clear any adhesive residues using a sponge soaked in solvent.
If the oven is heated up before removing the adhesive film, the removal of the film and cleaning of residues ofglue will be much more difficult.

1.4 INFORMATIVE LABELS
On each oven there are applied some labels, that give important info concerning characteristics of the oven, elec-tric and plumbing connections and eventually the drain connection. On the right hand side panel there is the label A.
The info contained on this label are:

• Name and address of the manufacturer
• Oven model
• Conformity to EC directives.
• Power input (single or three phase).
• Serial number of the oven

Close to the drain there is the label D, containing info concerning drain connection.
In proximity of water connection there is the label E.
Label E indicates water features necessary for a correct functioning of the oven.
Same features are listed at paragraph 2.3 of this manual.
WARNING! After installing the equipment and removing the protective film, clean the stainless steel as follows: clean with a soft cloth or a nylon sponge, soaked in warm soapy water or a mild neutral detergent, rinse with warm water and dry with a soft cloth (this procedure is very important as it avoids the later appearance of stains on the surface of the equipment).
Never use steel sponges because, in addition to scratching the equipment, they leave tiny particles that can trigger the appearance of stains and even oxidation.
The manufacturer declines any responsibility for oxidation resulting from the deficient removal of the stainless steel protective film and its inefficient cleaning. 1.5 POSITIONING OF THE OVEN
The place where the oven will be installed must comply the following requirements:

• Be protected from atmospheric agents and have an adequate air circulation;
• Comply with regulations concerning safety at work;
• Have a room temperature between 5 °C and 35 °C with a humidification not higher than 70%.
• Place the oven and proceed with levelling using adjustable feet.

Keep a suitable distance at the back, in order the label of equipotential clamp is easy to see when the oven has been installed. The same clamp must be easy to access to install equipotential cable after the oven has been installed in compliance with our instructions. Install the appliance in a position that allows access to the right side for installation, maintenance and technical assistance.

2.5 HYDRAULIC CONNECTION – WATER INLET
If the humidification system is installed, the ovens have a water inlet coupling at the back.
Always install an on-off valve between the appliance and the water mains, making sure it is easy to operate.
We also suggest installing a cartridge filter on the water inlet pipe.
Always use a set of new water joints, eventual old joints must not be used again.
Plumbing connection must be always effected with cold water and rigid pipes.
Never use hoses to connect the oven to the water main.
The water must be suitable to human use with the following characteristics:
Temperature: included between 15 – 20°C
Total hardness: included between 4 and 12 °f (French degrees), it is advisable to install a softener upstream from the appliance that will maintain the hardness level at the mentioned values.
Pressure: included between 150 and 250 KPa (1,5 – 2,5 bar).
Attention: higher water pressure values result in increased water consumption and can compromise the correct functioning of some components.
Maximum chloride concentration (Cl-): less than 150 mg/litre.
Chlorine concentration (Cl2): less than 0.2 mg/litre.
pH: more than 7.
Water conductivity: included between 50 and 2000 µS/cm.
Attention: Water treatment systems that bring to different values to the ones above mentioned automatically invalidate the guarantee.
The use of dosing systems designed to prevent the build-up of lime-scale in pipes (i.e. polyphosphate dosing systems) is also prohibited since it may impair the performance of the appliance.

2.5A HYDRAULIC DIAGRAM

3.1 REPLACING SPARE PARTS
The replacement of damaged parts must be done only by qualified personnel.
To request the manufacturer parts to be replaced must be provided the oven model and serial number.
These data can be found on the rating plate attached to the oven (see par. 1.4).
Before starting to replace spare parts make sure, for safety reasons, that the electricity main switch is off and that the water on-off valve are closed.

3.2 CHECKING THE FUNCTIONS
After completing the installation of the oven is necessary to perform a leak test to the water network.
The installer must check with suitable measurement instruments that the air noise emissions have a level of sound pressure type weighed A, less than 70 dB (A).

The label ISO 3864-1 here on the side must be stuck on a visible surface, 1,6 mt height from the ground.
On floor models, the label is already stuck in the suitable position.
On table models, the label is supplied along with the documentation and must be stuck after installation on a visible part of the appliance at 1.60 mt from the ground.
The installer must verify proper operation of the oven, providing the necessary instructions to the customer and give this instruction manual that the user must follow carefully.
IMPORTANT:
Before the operator turns the oven on and uses it for any cooking or washing cycle, it is necessary that the installer or a qualified technician checks all the connections have been done up to the instructions stated in our manual.
The technician or the installer must therefore check as follows:

• The oven must stand (horizontal position) and be fixed on a stand or a shelf, that can guarantee stability.
• Wiring connection must be effected according to the directives and the feed cable section must be no lower than the one indicated in the manual.
• Pressure and hardness of the water must comply the values indicated in this manual;
• If the oven is supplied with drain pipe, this must be connected properly and the materials used should withstand the working temperature.

After you have checked everything, open the water on-off valve, eventually the gas on-off valve and the protection switch, all installed upstream.
The installer must check the proper functioning of the oven and give to the operator necessary instructions for a correct use of the oven, and also verify that the operator owns a copy of this manual.
At the end the installer must fill in and sign the chart for correct installation and give it to the customer, who will keep it for all warranty period of the oven.

INSTRUCTIONS FOR A SAFE USE OF THE OVEN

• Ensure the oven is on a stable position and safety devices installed upstream are efficient.
• Always use adequate protection gloves to introduce or pull out the trays.
• Always pay maximum attention to the floor, that due to cooking steam could be slippery.
• In order to avoid burns, never use trays or containers with liquids or fluids over a level that can be easily controlled at sight.
• Don’t put trays or other kitchen tools on the oven.
• Periodically have a check with technical service and replace eventual damaged parts, that could alter the proper functioning of the oven or be a danger.
• Often clean the oven following the instructions stated in this manual.

MAINTENANCE

All external stainless steel parts should be:

1. cleaned with clear, soapy water;
2. rinsed with water;
3. dried thoroughly.

It is absolutely forbidden to use scrapers, metal soap pads and other common steel tools as they could besides scratching the surface, deposit iron particles that, oxidizing would cause rust to form.
DO NOT WASH THE APPLIANCE WITH JETS OF WATER
DO NOT USE PRODUCTS TO WASH THE STAINLESS STEEL PARTS, WHICH CONTAIN CHLOR (BLEACH, CHLORINE ACID) EVEN IF WATERED DOWN.
The oven cooking chamber must be cleaned from residues of food and fat at the end of each cooking process.
The juices and fat that drip from the food and fall to the bottom, are conveyed to the drain in the centre. To clean the oven, use a degreasing product suitable for stainless steel, a spray-on product for instance, that covers all areas, especially the back of the suction conveyor.
The fan must be kept clean to avoid grease and fat from depositing on the blades causing motor revolutions to decrease leading to a reduction in the flow of air and dangerous mechanical stress to the motor itself.
When the appliance is not used for long periods of time :

1. Turn the main switch off
2. Close the water on-off valve (both installed upstream from the oven);
3. Leave the door open so air can circulate and prevent bad odors;
4. With a cloth spread a thin protective layer of Vaseline oil on all stainless steel surfaces;

9.1 WHAT TO DO IN CASE OF A BREAKDOWN AND/OR EXTENDED PERIOD OF NON USE
If the oven does not work properly, breaks down or if the safety thermostat triggers, switch the oven off, discon- nect the electricity and water supply and notify the technical assistance service.

All work of installation, maintenance and repairs should be carried out exclusively by qualified and authorized personnel.
10.1 REMEDIES TO COOKING HITCHES
If cooking is uneven:
Check that there is at least 3 cm between the food cooking and the tray above it: if there is less space it will not allow correct ventilation of the food to be cooked. Make sure that the foods to cook are not against each other which would prevent correct ventilation between them.
Cooking temperature might be too high, try with a lower temperature. If the food cannot stand direct contact with the hot air it must be put in suitably deep G.N. containers.
If the food is dry:
Reduce cooking time.
The temperature must be adequately lowered. Remember that the lower the temperature is the less weight will be lost.
The combined cycle for a humidity rich cooking environment was not selected.
The food was not greased with oil or juices before it was put in to cook.
