-
Restore any damaged sections of insulation and insulate with high
temperature aluminium adhesive tape.
-
Carry out the above operations in reverse order to reassemble.
NOTE:
Check that the fans rotation direction is the one
stamped on the adjacent panel.
TT98E: Remove the back panel (fig. 38 part.T) and inner casing (fig. 38
part.S).
- Disconnect the wiring.
- Disconnect the fan wiring and remove the bracket and fan loosening the
3 fastening screws (fig. 38 part.K-Z).
- Remove the back panel of the baking chamber, loosening the fastening
screws.
- Move to a worktop.
NOTE:
BEFORE REMOVING THE FANS, BE SURE TO
NOTE THEIR EXACT POSITION SO AS TO REPLACE THEM
CORRECTLY.
- Loosen the fastening screws on the hub (Fig. 39 part A)
- Replace the fan, taking great care to refit it in the SAME POSITION
AND DIRECTION AS ITS PREDECESSOR and making sure that the
distance between the fan hub and motor base is the same as the one stated
in Fig 39
- To replace the motor, after disassembling the fan, proceed as follows:
- Remove the two screws fastening the motor (Fig. 39 part B)
- Loosen the back band locking the motor (fig.39 part C).
- Replace the motor.
- Fully tighten the two fastening screws of the motor (Fig. 39 part B)
and then tighten the nuts (Fig. 39 part G) compressing the split
washers as much as possible (Fig. 39 part H) so as to avoid excessive
deformation of the motor base.
- Carry out the steps in reverse order to reassemble.
NOTE:
Make sure that the fan rotation direction is the same as
that on the back panel of the baking chamber (fig. 39 part D and E).
NOTE:
If replacing the motor with thermal sensor (T64E:
Tab.C part 30 - TT96E: Tab.D part 46 - TT98E: Tab.B part 51),
remember to refit and restore the electrical connections.
5.12 FAN REPLACEMENT (if any)
After completing the steps in point 5.1, to replace the cooling fan, proceed
as follows:
TT96E TT98E
The fan is placed in the back on TT98E.
- Remove the back panel (fig. 38 part T) and inner casing (fig. 38 part S).
- Disconnect the wiring.
- Remove the fan bracket, loosening the 3 fastening screws (fig. 38
part.K-Z).
- Replace the fan.
- 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).
T64E
On T64E the fan is placed inside the electrical panel and positioned so as
to push air towards the engine compartment.
- Remove the rear panel by unfastening the fixing screws.
- To access the electrical components unscrew the 2 side fastening screws
and turn the side panel.
- Disconnect the fast-ons which connect the fan.
- Unscrew and remove the 2 screws securing the back of the fan.
- Loosen the two front fixing screws and move the fan towards the back
of the oven.
- Replace the fan.
- Carry out the steps in reverse order to reassemble.
NOTE:
Make sure that the fan is positioned so as to push the
air towards the engine compartment.
5.13 SETTING TEMPERATURES
CENTIGRADE/FAHRENHEIT
See chapter 3.2.16.
5.14 ADJUSTING SCREEN CONTRAST
Function not provided .
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.
TO DEGREES
UK/15
There is a pin set in the gear motor compartment. It is a good idea always
to keep a pin set handy.
After carrying out the operations described in point 5.1 above, to change
the pin proceed as follows:
- Remove the belt coupling cover (fig.16 part U) by unfastening the
screws that lock it in place (fig.16 part X).
- Align the holes in the coupling and the belt shaft and remove the broken
pin.
- Insert a new pin (fig.16 part S).
- Carry out the steps 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 (TT96E and
TT98E only)
The oven has two independent pressure switches: one for the right side
(fig.36 part Q) and one for the left side of the oven (fig.36 part P).
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 you detect any failure in the electronic operation, proceed with the
RESET procedure.
T75E - TT96E - TT98E
The RESET operation is useful to reset some parameters to their default
settings. This differs from "DEFAULT FACTORY SETTING" described
below because it does not change current configuration parameters, i.e. it
does not change the para meters on language, time, date, model set and
belt type, nor modifies the current gas parameters nor deletes any stored
baking programs.
Press MENU for the RESET procedure, select HELP and press "OK",
then select RESET and confirm to start the procedure. Press "OK" to
confirm or "RE TURN "to cancel the operation displayed on the screen.
NOTE:
To display the current configuration , see INFO tab under
the CUSTOMER CARE menu .
T64E
If turned off with main switch (fig.29b part.E) to position "0"
simultaneously press the " right" + "left arrows"(fig.29b part. 14 and
15) and press until main switch is turned on (fig.29b part.E) turning
to "1" position. This general reset operation will return the parameters to
their default settings. All settings return to default parameters.
5.18 "FACTORY DEFAULT PROCEDURE"
(only for T75E - TT96E - TT98E)
If you detect any failure in the electronic operation, proceed with the
RESET procedure described in 5.18. If the failure is not resolved or if
the LCD DISPLAY is replaced, perform the "FACTORY DEFAULT
procedure".
This procedure returns the electronic unit to the initial condition ; all data
contained within it are deleted, including the oven's configuration data
(gas parameters, model, etc.). The default operation will launch a
configuration wizard procedure to reconfigure the appliance properly.
The wizard requires the following information:
- language
- date/time
- model (see serial number plate fig. 3 part A)
- belt speed model (standard or fast)
WARNING!
If you are not qualified for even one of the
previous data, DO NOT perform these procedures! Contact the
manufacturer's specialized technical assistance.
WARNING!
Any Programs stored in the memory will be
deleted. Run the "EXPORT USB" procedure described in 3.6.7 to save
programs. Once the DEFAULT procedure is run, re-enter the saved
programs with the "IMPORT USB" procedure described in 3.6.7
