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

• Theappliancemustonlybeinstalledinadequatelyventilated 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.

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

3.1FOREWORD

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).

3.2WARNINGS 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 distance is defined on the basis of discharge pipe diameter "D".

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.

5. WATER MAINS CONNECTION

(Refer to the installation diagrams at the beginning of this booklet).

When connecting the appliance to the water system with flexible tubes they must be new and not used.

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 allow the water to flow out for sufficient time to flush any solid particles from the piping.

Pressure between 150 and 450 kPa (1.5-4.5 bar).

WATER INLET “N”

Attention (water inlet N)

If the supply pipes provided with the appliance are not long enough for installation, use longer ones with int. diameter at least ø 20 mm and free of elbow unions.

Note:

To check correct water installation, make sure the rotating wash arm (CLEANING SYSTEM) does not turn below 100 rpm (120 max).

^ 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.

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.

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.
