3.1 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 accord-
ing to the instructions given in the wiring diagram and fasten the
power supply cable by means of the cable clamp.
The manufacturer declines all responsibility if the applicable
safety regulations are disregarded.
4. WATER MAINS CONNECTION
(Refer to the installation diagrams at the beginning of this book-
let).
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).
4.1 WATER SUPPLY CHARACTERISTICS
The appliance must be supplied with
drinking water
having
specific characteristics given in this section.

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
251), if necessary installing at the inlet the type of filter indicated
in the relevant area of the values.
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
• The appliance must only be installed in adequately ventilated
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. ELECTRICAL CONNECTION
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
identification dataplate correspond with those of the power
supply.
• 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 conduit. If the
appliance is connected by way of an existing lead, do not insert
the cable conduit into the appliance and make particularly sure
that the conduit has no sharp edges.
• 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.
• Appliance maximum leakage current is 1 mA/kW
• 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 earth bonding system.
This connection is made using the stop screw marked
E
located on the outside of the appliance near the power cable
inlet.
The bonding wire must have a minimum cross-section of
10 mm
2
.
