• For disposal of the packing, see the section "The Environment"
• For the overall space required and connection dimensions,
refer to the installation diagrams given on the
fi
rst pages of this
instruction handbook.
• The left side of the appliance must remain at least
50
cm
from
other surfaces to enable maintenance operations, whereas the
right side and back must remain
10 cm
from any surface.
• Position the appliance on a
fl
at surface and, if necessary, adjust
the height of the worktop by means of the adjustable feet.
• The appliance is not suitable for built-in installation.
Attention:
Make sure the steam coming from the oven di-
scharge or adjacent appliances does not reach
the aeration vents (for cooling internal compo-
nents), located at the bottom of the appliance.
3. ELECTRICAL CONNECTION
• Connection to the electrical power supply must be done in
compliance with the current national and local regulations.
• Before connecting, make sure the voltage and frequency match
that given on the dataplate.
• The appliance must be connected to the power supply in a
permanent way. Connection must be made with an H05 RN-F
type cable. The power cable must be installed in a metal or rigid
plastic pipe without any sharp parts.
• An omnipolar switch of suitable capacity with contact opening
distance of at least 3 mm must be installed ahead of the appliance.
This switch must be installed in the building's permanent electrical
system, in the immediate vicinity of the appliance.
• A device (interlocked plug, lockable switch or similar devices)
lockable in the open position during maintenance must be installed
ahead of the appliance.
• Appliance max. leakage current is 5 mA.
• The appliance must be connected to an effi cient earthing system.
For that purpose, the connection terminal block
has a terminal with the symbol
for connecting the earth wire.
The appliance must also be included in an equipotential system.
This connection is made with the setscrew marked
E
, located
externally near the power cable entry.
The equipotential wire must have a section of at least 10 mm
2
.
3.1 POWER CABLE INSTALLATION
To connect the power cable to the appliance, proceed as follows:
Model 6 - 10 - 20 GN
• Remove the left side panel.
• Connect the cable to the terminal block as shown in the wiring
diagram attached to the appliance, and secure it with the special
cable gland.
The manufacturer declines any liability if the current national
and local regulations and possible safety regulations are
not respected.
4. WATER CONNECTION
(See the installation diagrams at the beginning of this handbook)
When connecting the appliance to the water system with
fl exible tubes they must be new and not used.
The oven has two separate inlets ("B" and "N") for the supply water.
The supply pipes of both inlets must be equipped with a mechanical
fi lter and shutoff cock. Before installing the fi lters, it is advisable
to let a certain amount of water fl ow in order to clean the pipe of
any solid particles.
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 SUPPLY WATER CHARACTERISTICS
The appliance must be supplied with
drinking water
having the
specifi c characteristics given in this section.
HARDNESS FILTER
The
hardness
values given in the table are for reducing scaling
inside the steam generator and for the oven compartment cleaning
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
chlorine concentration (Cl-) (ppm - mg/l)
values with
pH
(>7) and
Conductivity (µS/cm)
(measured at 20°C) must be
such as not to harm the steel structures inside the oven (water
inlet B only).
For that purpose it is necessary to identify the characteristics of
the available water on the graph given on the last pages of this
handbook (page 299), and if necessary install at the inlet the type
of fi lter indicated in the relevant area of values.
The fi lters indicated are:
- No fi lter for chloride (Cl-) in the conforming area (Normal)
- Nanofi lter
as an accessory on request, called Water Filter.
- Osmotizer.
Check that the water coming out the fi lter is inside the optimum
area (Normal).
These fi lters also reduce the water hardness to optimum values
(below 5°f), and therefore also act as a softener.
