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 as follows (fig. 1a-1b-1c), 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).

5938 036 01

Electrolux Professional AOS062GCP2, AOS201GAP1 Owner’s Manual

			USA
3.2 WARNINGS REGARDING THE FLUING SYSTEM		CONSTRUCTION TYPE	1b
Before installation check, on the basis of the contents of the		CONSTRUCTION TYPE
		B13
reference standard, to ensure that the volume aspirated by the		B13
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 762"(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 0.14"(3.5

4. ELECTRICAL CONNECTION

•A fused disconnect switch or main circuit breaker (customer furnished) MUST be installed in the electric supply line for the appliance. It is recommended that this switch/circuit breaker have lockout/tagout capability. Before making any electrical connections to this appliance, check that the power supply is adequate for the voltage, amperage, and phase requirements on the rating plate.

•A safety cutout switch of suitable capacity with a contact breaking distance of at least 3 mm must be fitted upstream of the appliance.

The cutout switch must be installed near the appliance in the permanent electrical system of the premises.

•The appliance must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.

The grounding conductor must therefore be connected to the terminal marked Gon the connection terminal board. The appliance must also be connected to an earth grounding system.

This connection is made using the stop screw marked E located on the outside of the appliance near the power cable inlet.

The grounding wire must have a minimum cross-section of 8 AWG (10 mm2).

RATING PLATE

4.1 INSTALLING THE POWER SUPPLY CABLE

To access the power supply cable connection terminal board, proceed as follows:

Model 6 - 10 - 20 GN

•Remove the left side panel.

•Connect the power supply cable to the terminal board according to the instructions given in the wiring diagram and fasten the power supply cable by means of strain-relief fitting (not furnished with the oven).

Failure to comply with safety rules and regulations relieves the manufacturer of all liability.

The manufacturer requires when stacking units each appliance have its own branch circuit protection. An oven unit stacked with an blast chiller unit should have a separate protection for the upper and lower units.

5. WATER MAINS CONNECTION

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

This equipment is to be installed to comply with the applicable Federal, State, Local plumbing codes, or the Basic Plumbing Code of the Building Officials and Code Administrators International Inc. (BOCA) and Food Service Sanitation Manual of the Food and Drug Administration (FDA).

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 valve (keeping with local plumbing codes).

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

Pressure between 22 and 65 psi (150-450 kPa).

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 3/4" (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).

5.1 WATER SUPPLY CHARACTERISTICS

The appliance must be supplied with drinking water having specific characteristics given in this section.

^ 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 68°F)(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 107), 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 50ppm)(5°fH), 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.
