work that was performed, which must be kept for at least ten years. The unit must be placed on a solid, flat, and well levelled surface as large as the
base.
There must be at least 25 cm of space around the unit to allow proper ventilation and the access for cleaning and any necessary
maintenance . Do not put free flames close to the appliance or use them inside the oven or nearby it.
Please be sure that the chamber must be free from any plastic or cartoon or similar objects to avoid danger or flames. You must check also under the
refractory stone.
NOT STOCKABLE NEITHER RECESSABLE EVEN IF PARTIALLY
OVEN INSTALLATION
Place the appliance with the support, in case the oven is equiped with it, in the room where you need to install the oven, paying attention to choose a
position where it can be easily plugged to the power supply network as well as nearby to the operator and appliance protections. Leave enough space
around the unit for its ventilation and for the cleaning. The oven's base and the frame's feet must rest on a solid, flat surface. The frame does not require
to be anchored to the ground. When the appliance has been placed, check with the level by positioning it on the oven first lengthwise and then
crosswise if the appliance is well established. If necessary, screw or unscrew the oven feet.
INFORMATION ABOUT ELECTRICAL PLANT
The electric parts of the oven are as follows:
- 2 thermostats for regulation and controll of the baking room temperature;
- orange switch for baking room internal light;
- detector light for the functioning of regulation thermostat;
- armoured electrical heating elements;
- outer electric terminal block placed on the rear side of the appliance;
- general connection wiring of appliance circuit devices, realized with cables suitable to the heavy
conditions of job and adequate overvoltage limit.
All the AMM ovens can be plugged through a 5x4 mm2 wire.
CONNECTING TO ELECTRICAL NETWORK
The link to the electrical network and put in service of the device must be done by a specialized
and expert technician, following the technical and normative arrangements of the country of
installation. Arrange a line log near the equipment, so that the installed cable, can reach the
power plug. Do not use extension cables, for this link. Install a box to contain the installation
devices. The appliance must be connected to the network power supply through a three-phase
feeding cable, with neutral of adequate length, with a yellow/green line of earth. To the extremity
must be installed a unified CEE socket, in conformity with the standard IEC 309-2 "sockets and
plugs for industrial use" of the type suitable for the feeding tension and for the nominal current
absorbed by the device, as indicated on the electrical diagram and in the section “Technical
Characteristics”. Refer to the information listed on the Technical Data Plate. The specialized
installer must install the following components in compliance with current standards in the Country
in which the unit will be used:
- a wiring cable with suitable electrical socket and plug;
- a disconnection switch;
- a thermal disconnector and differential switch whose sensitivity is suitable to the current leakage
(fig. 1)
from the heating elements. It is user's responsibility to install these components near the location
where the unit has to be installed. The unit must be connected to the ground by means of an
efficient system. Carefully check the conditions and features of the ground system both visually
than with instruments. Repair it if necessary.
Make the connection according to the indicated technical procedures; respect the cyclical
sequence of the connection of the phases and the wire color codes:
- L1 – phase R Position on the Terminal Block: 1
- L2 – phase S Position on the Terminal Block: 2
- L3 – phase T Position on the Terminal Block: 3
- N – Neutral – Light Blue colour.
Position on the Terminal Block: 4-5 linked by bridge
- Earth = protection wire – stripped Yellow/Green color.
For all “F” models, a 5x4-mm2 wire is allowed.
When you have finished connecting the equipment for the oven's power supply protection, make a (fig.2)
functioning test using the instrument for testing the differential switch's efficiency.
Verify that the oven absolutely doesn’t contain any type of combustible or other objects. Check that
the oven can be activated for the preliminary test. Do not remove any protection board from the
oven. Make sure that the unit’s main power switch is on the O/OFF position. Turn the thermostat
knob to set an average temperature of approximately 150° C. Turn the power switch of heating
elements to I/ON, so to heat the oven. Verify that the current is being absorbed and that all the
installed heating elements are correctly functioning. Wait until the circuit is interrupted by the
thermostat and turn off the main power switch to zero. Now the oven's functioning has been
verified. After the equipment has been connected and the functional test of the oven has been
performed, the installer must issue the required declaration that the work has been performed
perfectly.
The appliance must be connected to an equipotential system whose effectiveness
must be verified in accordance with the regulations in force. This connection must
be made between different devices using the appropriate terminal which is marked
with the symbol in the figure. The equipment must be connected to the ground line
(tab.1)
of the power grid. The bonding conductor shall have a minimum cross section of
2.5 mm2. The equipotential terminal is located on the back of the oven.
