4. Instructions for the installer
The following instructions are aimed at the qualified installer, to ensure that he carries out the
installation, adjustment and maintenance operations as correctly as possible and according to
current legal regulations. Any operation must be performed with electrical power cut to the
appliance.
Before using the appliance, carefully remove the special adhesive film protecting the parts in
stainless steel. Do not leave any glue residues on the surfaces. If necessary, remove them at once,
with an appropriate solvent.
Fitting the feet - The feet are inside the appliance and must be secured on the four threaded holes
on the base. If necessary, the height of the feet can be adjusted by screwing or unscrewing.
Positioning - Position the appliance perfectly horizontally on a table or similar support (the table or
support must be at least 85 cm above the floor). Position it at a distance of not less than 10 cm
from the side and rear walls, to enable natural ventilating air to circulate freely around it.
The appliance is not suitable for embedding and for grouped positioning with other identical
appliances.
Electrical connection - The appliance must be connected to the electrical mains according to
current legal regulations. Before making the connection, make sure of the following:
-
the voltage and frequency values of the power supply system match the values on the
"technical data" plate affixed on the appliance;
-
the limiting valve and the system are able to support the appliance's load (see the
"technical data" plate);
-
the power supply system has an adequate earth connection according to current legal
regulations;
-
a omnipolar switch with minimum between-contacts aperture of the overvoltage category
III (4000 V), sized to the load and conforming to current legal regulations, is fitted between
the appliance and the mains in the direct connection to the mains;
-
the omnipolar switch used for connection is easy to reach when the appliance is installed;
-
the yellow/green earth wire is not interrupted by the switch;
-
the power supply, when the appliance is operating, must not deviate from the rated voltage
value by ±10%;
-
make sure that after inserting the power supply cord into the terminal block it does not
come into contact with any of the cooking range's hot parts.
-
if the supply cable is damaged then it must be replaced by the manufacturer or by your
technical support or by a qualified person to avoid any risk.
Connection to the water mains - (for ovens predisposed to humidifier solenoid-valve)
The appliance must be fed with softened drinking water, with pressure in the range from 100 to
200 kPa (1.0 - 2.0 bar). Water must have hardness from 0.5°F to 3°F (it is suggstible to use a
softener as to avoid the malfunction of the fan, the breakage of the heating element and to
reduce the formation of lime inside the cooking chamber). Connection to the water mains should
be made through the threaded 3/4" solenoid-valve on the rear (on the bottom) of the appliance,
fitting in between a mechanical filter and an on/off tap (before you connect the filter, allow a
certain quantity of water to flow out in order to drain any waste from the pipe).
Connection to water tank - (for ovens predisposed to water pump)
To replace electrovalve with water pump (in ovens with optional predisposition to pump), follow
the steps below listed (image 1):
1)
Remove back cover from oven.
2)
Disconnect wiring cables from electrovalve.
3)
Disconnect water tube (3) from electrovalve, pressing e keeping pressed the edge of black
linking (quick insertion).
4)
Remove the electrovalve unscrewing the screw that fix it to oven’s frame.
