8. MAINTENANCE
WARNING: the maintenance instruction contained here are for the use of qualified
maintenance and service personnel only. Maintenance or service by unqualified
personnel may create damages to the appliance and/or injury to the operator.
To perform maintenance and service in most cases it is necessary to remove safety
enclosures. This makes accessible some live conductors and/or parts in motion.
Before removing any safety enclosure check that the main plug is disconnected from
the socket of the switchboard and put the plug in an easily to-be-checked position by the
personnel.
8.1 ERROR INDICATOR
The electronic thermo-regulator can detect various malfunctions, for details see 5.6.
8.2 SAFETY THERMOSTAT
If the chamber temperature exceeds 500°C., the safety thermostat is activated and closes
the gas valve. The safety thermostat is reset manually and is at the external side of the oven
electric board or on the left side of the control panel under the conveyor.
To correct the error, disconnect the plug from the electric panel, close the gas valve and wait
until the chamber cools down.
Remove the right side panel of the electric board and press the red push-button on the
thermostat. Reset will take place only when the chamber temperature has gone below the
temperature of 500°C.
Since the safety thermostat is activated only in case of serious damages (for instance if
the gas valve ON/OFF is blocked open), before starting the oven again check carefully the good
working of the same and perform the required reparations.
