- Carry out the steps in reverse order to reassemble.
NOTE: make sure that the rotation direction is the same as
shown on the panel (fig. 38 part U).

SETTING
TEMPERATURES
CENTIGRADE/FAHRENHEIT
The control unit can be set to display temperature in Centigrade or in
Fahrenheit. When changing from one setting to another, once the
dip-switch has been set to the position required the variation will
become operative as soon as one of the key is pressed, or the first
time the image displayed on the monitor is refreshed.
After carrying out the operations described in 5.1 above, to change
the settings proceed as follows:
- Unfasten the control panel fixing screws (fig. 21 item H).
- Change the dip-switch (fig. 21 item 3) on the control panel LCD
monitor to OFF or ON according to the temperature scale you wish
to use, as follows:
N°
OFF

degrees Centigrade

- - Perform the above operations in reverse order to reassemble.
5.14 ADJUSTING SCREEN CONTRAST
After carrying out the operations described in 5.1 above, to adjust the
screen contrast proceed as follows:
- Unfasten the control panel fixing screws (fig.21 item H).
- Using a small screwdriver, turn the adjustment screw (fig.21 item
B) to obtain the required contrast.
- Perform the above operations in reverse order to reassemble.
5.15 REPLACING THE BELT DRIVE PIN
The belt shaft is driven by a safety pin, calibrated to break in the
event of excessive drive stress.
After carrying out the operations described in 5.1 above, to replace
the pin proceed as follows:
- Remove the belt coupling cover (fig.16 item U) by unfastening the
screws that lock it in place (fig.16 item X).
- Align the holes in the coupling and the belt shaft and remove the
broken pin.
- Insert a new pin (fig.16 item S).
- Perform the above operations in reverse order to reassemble.
WARNING! Only use original replacement pins, as they are
made of a special material designed to guarantee breakage in the
event of excessive stress.
If other materials are used there is a severe risk of being dragged
by the belt.
5.16 PRESSURE SWITCH REPLACEMENT (TT98E only)
The oven has two independent pressure switches: one for the right
side (fig.36 part.P) and one for the left side of the oven (fig.36
part.Q). In case of a lack of ventilation, it serves to de-activate the
heating elements on the corresponding side (if there is an anomaly in
the CEILING temperature, look for it on the left side, while for
FLOOR anomalies, look on the right side).
To replace, carry out the operations described in point 5.1, and
proceed as follows:
- Open the electrical panel from the side concerned, following the
procedure described in point 5.3.1.
- Disconnect the electrical connections and air pipe.
- Replace the pressure switch.
- To refit, carry out the above steps in reverse order, taking care to
connect the component correctly.
5.17 GENERAL RESET PROCEDURE
If any electronic malfunctions are encountered, or when one of the
electronic cards is replaced, it is advisable to carry out a general
reset.
Access the parameters menu by pressing the OK and down arrow
buttons simultaneously for 5 seconds (fig. 29 items 13 and 10).
Press the up-down-right arrows simultaneously for 5 seconds (fig.
29 items 9, 10 and 11) to carry out a general reset, which restores the
parameters to the default values (this will be confirmed by a number
of beeps).
The reset also zeros the clock, which will have to be reset.

5.18 DISPOSAL
When the oven or spare parts are dismantled, the various components
must be separated according to type of material, and then disposed of
in conformity with current laws and regulations.
The presence of a barred mobile container indicates
that within the European Union electrical components
are subject to special disposal at the end of their
working life. This rule applies not only to this device,
but also to all the accessories marked with this
symbol. These products must not be disposed of
together with normal household waste.
