that the burner fan is underpowered and the fan fails to reach the
expected speed. Also check the pressure switch and its circuit; ensure
that the two air capture metal pipes for pressure switches are clean.
M Electronic card malfunction alarm (
-This indicates a fault in the electronic card directing the burner flame
control. The alarm detects a condition of danger when there is an
abnormal flame when operated: during the cooling process or if the
measured temperature is higher than the set point.
In this case the shutdown procedure takes only 3 minutes (compared
to 30 minutes) after which the oven turns off automatically; the next
time you restart a message is displayed indicating a fault after the last
shutdown.
Contact specialized technical assistance to resolve the cause of the
failure; ensure that no oven component was damaged and
eventually replace it.
The following SIGNALS may be displayed if there are any failures:
N Switchboard over-temperature
-This indicates that the temperature of the electric components
compartment has exceeded the threshold limit. T64G T97G TT98G:
check cooling fan operation (fig. 52 item Y).
P Pressure switch Failure ( TT98G)
-It inspects the integrity of the pressure switch during the start process
.Contact specialized technical assistance to resolve the cause of the
failure; ensure that no oven component was damaged and eventually
replace it.
Q Abnormal shut down (
T75G-T97G-TT98G)
-displayed at start-up and indicates that the oven was previously
turned off incorrectly, and the provisions of paragraph 3.7. were not
followed.
WARNING!
the abnormal shut down signal must not be
taken into consideration ONLY in the following cases:
1. there is a real condition of danger so the oven is switched off
using the emergency mushroom button (fig.29 item O)
2. there is a temporary and sudden interruption of electricity
supply for external causes not caused by the user.
In all other cases follow the procedure to switch off the oven
appropriately, otherwise it will break down permanently!
When there is a signal, the control unit shows the type of signal on the
screen. Press OK (fig. 31 Pos. 15) to acknowledge the visual and
acoustic signal (if any) and the message disappears. If necessary,
finish cooking and contact customer service.
3.7 STOP
T64G:
To stop the appliance, press the STOP button (fig. 31b item 17); the
fan will continue for about 30 minutes to bring down the
temperature gradually and safeguard the duration of the
components; only after this time should the power be disconnected
turning the switch to position "0" (fig. 31b item E).
WARNING!
In an emergency, cut the power by turning
the main switch to "0" (fig. 31b item E).
T75G-T97G-TT98G
To stop the oven, press STOP (fig.31 item18); the fan will continue
for about 30 minutes to bring down the temperature gradually
and safeguard the duration of the components; after this time and
the time required to cool down oven parts, the oven will switch off
by itself.
NOTE:
Avoid abrupt shutdowns. If you need to turn off the
oven before it turns off by itself, wait until the oven reaches
temperatures below 100° C (210° F), then press and hold the
STOP button for a few seconds (fig. 31 item 18), and
"SHUTDOWN" will be displayed; press OK to confirm the
shutdown process and the oven will be disconnected from the
power supply after 1 minute or press RETURN to cancel the
operation and return to the main screen.
WARNING!
In an emergency, disconnect the power supply
by pressing the emergency mushroom head button (fig.29 item O).
NOTE:
After the emergency mushroom head button has been
pressed, (fig.29 item O) it will remain pressed in the safety position
until, once the emergency is over, it is unlocked by turning it
anticlockwise.
3.8 USE
T75G-T97G-TT98G)
After setting the cooking parameters desired, prepare the product to be
cooked on a special support (screen, pan etc.) and ensure it does not get
out from the mesh holes; place it on the conveyor belt from the input
side to the cooking chamber; it will be extracted cooked from the
opposite side.
If you have no experience on the values to be set start cooking at
temperatures of 310° C/590° F (TT98G° C 270/520° F) and 4' cooking
time; then depending on the first cooking result, change the parameters
to find the best ones for your needs; the temperature is generally raised
to increase browning and cooking time is increased. For smooth
cooking results, avoid temperatures higher than those recommended for
the type of product to be cooked.
It takes about 25/35 minutes to reach the right temperature; after the
temperature has stabilized start cooking.
NOTE:
The estimated time required to bring the oven to the
desired temperature shown in the heating process in the messages
bar from T75G T97G TT98G (fig. 30 item 3) is indicative and may
vary considerably with respect to parameters when started .
WARNING!
taken
from the oven with the suitable accident prevention equipment
such as pizza containers etc. (fig.35 item O) with utmost care;do not
operate near oven moving parts if the oven is baking ;all operations
must be performed after switching off the oven.
On T75G T97G and TT98G the cooking phases can be observed
through the glass on the front door. If you need to operate on the
product, for example, to break the bubbles that may be created on pizza
with a puncture tool, carefully open the door using the front handle (fig.
35 item Q).
WARNING!

equipment is not hooked up to the conveyor tape and that body
parts are not dragged inside.
Under no circumstances must any part of the body be inserted into
the chamber, as there is a severe risk of burning or getting caught

is high up with respect to the operator.
4 ROUTINE MAINTENANCE
4.1 PRELIMINARY CONTROL OPERATIONS WARNING!
Before performing any maintenance operation stop the appliance
as described in the procedure in point 3.7 and cut the power
supply, then disconnect the power supply by turning off the power
cable outside the oven. Stop gas supply. Operations must only be
carried out after the oven has been allowed to cool down.
All maintenance operations must be carried out by qualified
technicians using suitable accident prevention equipment. All
precautions are of importance to ensure that the oven remains in a
good state, and failure to observe them may result in serious
damage which will not be covered by the warranty, as well as
causing risks.
4.2 ROUTINE CLEANING
After carrying out the operations described in point 4.1 above, clean
the appliance as follows:
Every day, at the end of operations and after leaving the appliance to
cool down, carefully remove from all parts of the oven, any residues
that might have collected during cooking, using a damp sponge or
cloth and a little soapy water, if necessary. Rinse and dry the areas,
being sure to wipe parts with satin finish in the direction of the finish.
Carefully clean all accessible parts.
NOTE:
Regularly clean the rear vents (fig. 10 item A) for air
intake. A lack of cleanliness can cause parts to overheat.
NOTE:
Clean the belt with a stiff nylon brush.
Slide out the flour trays on the left and right (fig.14 item T); clean and
refit them.
