"Reset" Procedure - Nordcap MORETTI T75G Mode D'emploi

- Carry out the steps in reverse order to reassemble; use high
temperature lubricant to refit the 4 screws on the burner head
Repair the damaged insulation containment.
- After connection when the oven is on, perform a gas leak test with
particular attention to areas operated with a spray leak detector, which
does not cause corrosion. Never use open flames to identify gas
leaks.
- Switch off the appliance.
- Remove the protective guard (fig.20 item M)
- Close the electrical panel following the steps in section 5.3.4.
5.16 REPLACING
COMPONENTS
After carrying out the operations described in section 5.1 above, to
replace components,of the combustion chamber proceed as follows:
- Remove the burner cover (fig. 20 item M).
- Remove and replace the component.
WARNING!
If you replace the VENTURI cone, use a
large screwdriver to adjust the gas at X = see technical data TAB.
1 for the gas type (paragraph) 3. Check X with a GAUGE for
accurate results and fix the seal on the gas regulator with a red
heat-resistant paint.
- After replacing any component of the combustion chamber, reset the
following on the gas valve:
- Open the gas tap.
- Loosen the retention screw inside the gas valve output pressure
takeoff (fig. 27 item T)
- Connect the pressure gauge correctly reset to the pressure takeoff.
- Turn the appliance on as indicated in the instructions.
- At start-up the pressure value initially varies; wait until the burner is
lit, then check the pressure at that point. The value must be 0 mbar on
the gas valve, otherwise remove the cap (fig. 28 item U) and adjust
the screw below (fig. 28 item Z) until the pressure value reaches 0
mbar.
- Turn the appliance off as described in the instructions.
- Remove the pressure gauge.
- Fasten the retention screw (fig. 27 item T) and replace the cap on the
gas valve (fig. 28 item U)
- After connection when the oven is on, perform a gas leak test with
particular attention to areas operated, with a spray leak detector,
which does not cause corrosion. Never use an open flame to search
for gas leaks.
- Switch off the appliance.
- Fix the seal on the gas regulator cap with red heat-resistant paint.
- Reassemble the burner cover (fig. 20 item M) and ensure there are
no holes where unfiltered air can flow (T75G).
5.17 COMBUSTION CHAMBER REPLACEMENT SHIELD
T75G-TT98G
After carrying out the operations described in section 5.1 above, to
replace the combustion chamber shield, proceed as follows
T75G: Remove the rear panel (fig.38 item D) by unfastening the
fixing screws.
- Disconnect the motor electrical connections.
- Remove the braid clamping strips by unfastening the
fixing screws.
- Move the insulation and dismantle the rear cooking chamber panel by
unfastening the fixing screws.
- Unfasten the 4 locking screws and remove the shield from the fan air
intake hole.
- Remove the belt and blowers as indicated for the front shield
- in section 5.2.1., unfasten the 4 locking screws and remove the shield
from the fan air intake hole.
- Carry out the steps in reverse order to reassemble (see section 5.2.2).
- Restore any damaged insulation sections and insulate with high
temperature aluminium adhesive tape.
TT98G: Remove the back panel (fig. 52 item T) and inner casing (fig.
52 item S).
- Disconnect the wiring
- Electrically disconnect the fan and remove the fan bracket by
unscrewing the 3 fixing screws 3 (fig. 52 item K-Z).
- Remove the back panel of the cooking chamber, loosening the
fastening screws.
- Replace the shields and when you refit on the screws and nuts, use
high temperature lubricant .
- Carry out the steps in reverse order to reassemble.
COMBUSTION CHAMBER
NOTE:
The shields are partially visible if you open the oven's
front door on TT98G, for partial inspection (fig. 16 item S) and by
inspecting below the lower blower right to left

"RESET" PROCEDURE

If any electronic malfunctions are encountered, or when one of the
electronic boards is replaced, it is advisable to carry out a general reset.
T75G-TT98G:
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 cooking 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
and for parameters
PARAMETERS , both found under the CUSTOMER CARE menu.
T64G:
With the appliance switched off and the main switch (fig. 31b item E)
set to "0", press the "Right arrow" + "Left arrow" (fig.31 b item 14
and 15) together and holding them down, enable the main switch
(fig.31b item E) moving it to position "1". This general reset operation
will return the parameters to their default settings. All settings are reset
to factory values.
The positive outcome of the operation is shown in the control panel,
which will show rSt ("Reset") for a few seconds, followed by the
preset gas parameter, which will flash. Use the "Up/Down Arrow"
keys to scroll through the list of predefined gas types (G20, G25, G30,
G31, uLPG) through to the type of gas for which the oven was
designed (see gas rating plate, fig. 2 item G) and press OK to confirm
(fig. 31b item 16). If it is necessary to use a different set of gas
parameters, select the letters GAS which allows the setting to be
configured manually, as described in 3.4.4.
NOTE:
It is possible to view the current gas configuration for
some instants from the control panel when the equipment is being
switched on. At this stage, the software version installed on the
control panel is also viewed. To view the gas parameter setting,
follow the procedure 3.4.4.
5.19 "FACTORY DEFAULT PROCEDURE"
for T75G-TT98G)
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 item A)
- belt speed model (standard or fast)
- type of gas (methane or LPG) (see serial number plate fig. 3 item
H)
NOTE:
- gas parameters
shown in TAB. 1 for the type of gas per country of installation!
Modify them with the up/down arrow keys to mark the parameter
and use "+" and "-" to modify them.
WARNING!
previous data, DO NOT perform these procedures! Contact the
manufacturer's specialized technical assistance.

save programs. Once the DEFAULT procedure is run, re-enter the
saved programs with the "IMPORT USB" procedure described in
3.6.7
To start the process, press MENU, select HELP and press "OK" to
enter the FACTORY DEFAULT, and confirm. Press "OK" to confirm
